A couple of years ago I needed a project and started looking for something i could build into a midmounted track car or even a certified road car. A rather untidy looking 914 appeared on trademe in the south island (NZ) The car had been part of a consignment of vehicles that had been imported and the chap had a few difficulties and they ended up being auctioned off. I purchased the car six or eight months later and had it delivered up to the North Island for a couple of hundred dollars more than i paid for the car. I had just sold a lotus seven replica sports car so went to see a friend about starting the 914 project

returf
Well the thing i did wrong was to go to his work with all this money in my pocket, as there in the corner of his shop lay another of my childhood dream cars, an e type jaguar. ten minutes later I owned the jag and had no money left to move on the 914. So it was back to my shed and find a place for the 914 to stay for the next wee while until I could finish the e type Click to view attachment

I cobbled together a good ole four poster to sit the 914 on and there it stayed for 18 months

With the Jaguar finished it was time to bring the 914 down Click to view attachment

I spent some time looking at pictures of great looking 914's on google images and in particular the wide body race cars the likes of Sheridans and papa smurf. I printed a couple of photo's out and stuck them to the door for inspiration

Now down here in New Zealand Porsche six cylinder engines are very hard to get and when they become available you have to pay mega dollars for them so It was an easy decision to go the v6 or v8 path. For no other reason than locality and price I purchased an ls1 , computer and engine loom for the project.
After the first cut of sheet-metal things got a bit easier and before I knew it the motor fitted in the hole!!Click to view attachment
About this time i started thinking about gearboxes. Again Porsche boxes are hellish dear if you can find them so I found a Renault UN1 as that's what one of our local car builders uses behind his Lexus v8 powered lambo kit cars. Next step was to fabricate a good sounding exhaust

What a way to waste time and money but man the sound was awesome.

Wow, you've got a couple of nice projects there. How about posting a couple of pics of the finished Jag? I like E-types and the Minilites look great on it.

What did the Renault UN1 come out of? I've never heard of that transmission. Its must be rated for some pretty good torque if you're putting it behind an LS1.

the un1 trans comes out of the Renault 25gtx. they are fairly strong boxes and pretty inexpensive ( 3-500 $ ) they will hold up to 350 ft/lbs ok with over 400 hp

However!!!!!!!

cont-However!!!!
My son came out to the shed one night and said" the dollars high dad, wouldn't this go good with a turbo? " Good on ya boy. Two weeks later a package arrives with a lovely big hair drier inside. And this is what i mean in my previous post about a waste of time and money fabricating those crossover headers

Now this poses the next hurdle to overcome. It will definitely destroy the Renault box. Maybe if I just drive it gently I fleetingly thought! yea right.
Porsche boxes are'nt getting any cheaper. but wait! what about the six speed subaru box? the track boys are getting huge hp to the ground around the world. The hunt was on and i started looking around the local area. Luckily a bloke a few kms away makes the Saker Sports cars and converts the 4wd subaru boxes to 2wd for his cars and pointed me in the direction of a very low km 6 speed.
returf
Next on the agenda was to organise a clutch , pressure plate and flywheel for the now somewhat increased power level expected.I got on to a bloke in Auckland that races high powered Subarus and is a very clever engineer and between the two of us ( that is me measuring and him making) he came back with a flywheel of beautyClick to view attachment This was cnc'd out of chrome moly and then gear cut and hardened. absolutely brilliant job from midway motorsports thanks Jase!
db9146
BEAUTIFUL E-type!!! Love it. Mean and classy at the same time.

Yea, I've read a number of posts where guys are buying up the Saker parts to convert the more readily available 4WD Subaru boxes into 2WD for mid-engine use. I've been thinking about using one behind a 3.6 Porsche. The G50 Porsche transaxles are too expensive and you have to run them inverted. That's why I was asking about the UN1.

You are absolutely right on the flywheel.

I'll be watchin' your progress!!!!!

Dave Short here uses the un1 in his lambo replica's with really wide tyres and 1400kg car. As i said he runs about 400 hp through a supercharged 1uz toyota v8 and with road driving and no crazy dumping of the clutch it lives quite happily.
returf
Right, the next thing that needed to be taken care of was an adapter plate for the Subie box to mate to the LS1. this proved not to be a big deal but care was needed to drill the holes in the right place. a piece of 20mm steel was profile cut, cleaned up, marked, checked and drilled. Click to view attachment
then install the clutch and pressure plate and bring them together. Look who's watching the progress, lil ole e type.Click to view attachment
returf
with the engine and gearbox mounted together it was time to move on with mounting the other necessary bits like intercooler and pipework[attachment

gazing upward it became obvious that there might be a small problem with axle alignment and then there's the issue of 4 stud hubs and average brakes in the rear. mmm what to do?? the approach I had to take was fix the whole lot at once sooo.
replace the hub with that from a wrx front setup, cut the trailing arm off at the tube and extend it by 90mm rearward and 60mm outward. done!! Now I can use standard length subaru axles that have the right alignment, bolt on the vented front rotors off any high performance Subaru and adapt 4 piston calipers.

returf
At about this time I decided that the e type thing had run it's course and put it on the market. Because I had done some very bad things to the e type like fitting a 302 windsor v8 and toyota 5 speed box, eliminating all the things jag lovesr desire in their e type ( oil leaks) the jaguar purists were'nt lining up to buy it. Instead a sharp eyed gentleman from Australia spotted it and travelled the distance to purchase it. Now I had all this money to spend on the project car where would i start??Click to view attachment

why am I such an impulsive person when I've got money
returf
About this time I am starting to stare blankly at the project when I get a visit from a mate of mine that had started as a tutor in Motorsport. One thing led to another and he made the suggestion that his students could benefit from something a little out of the ordinary to develop their skills as motorsport fabricators. Well impulsive I may be but supportive of the need to foster young minds I am also! This also meant I now had timelines to meet with regard to the mechanicals and Brent set me up with a whiteboard list of things to get done before their term started. I had to purchase a set of adjustable coil overs and some new struts and hubs for the front. Seeing as we now have 5 stud hubs for the rear we might as well have 5 studs for the front. I got a set of nissan sylvia uprights that had GTR discs adapted to them. 325mm vented rotors and 4 piston calipers ought to stop this little sucker!!Click to view attachment
My son had being doing a lot of study on suspension so has been advising me as to the correct setup for steering arms, bottom arms and control arms ( seems a little odd really, all these years he's never listened to me but now I'm supposed to listen and do whatever he says )
Another of my friends was in around the same time and looking at the car he stated "it looks just like an rx7 to me front on" followed by " give jonesy a ring he has an old GT1 front lying around that has had a biff, it might fit" Well he wasn't too far wrong as it happens

Master cylinders, brake lines were next on the agenda. After a quite bizarre quest of trying to re-invent the braking system I came to my senses and succumbed to a willwood hung pedal box complete with brake bias. Does any one else out there in project land waste time and money trying to save money?? arrghClick to view attachment

So the list got shorter and eventually the car was needed over at UCOL Motorsport to get things happening. Brent wanted me to drive the car into their workshop under it's own power

so this is the sunday before d:)

So to recap so far: engine, gearbox, axles, brakes, suspension; Everything's All Sorted!! well not quite! What about shifter, throttle, radiator to get this thing driving. Now many of you guys wont understand this, but i've been driving for forty years with a gear shift on the left hand side of my left leg and doing the steering thing with one strong right arm. All of this training isn't about to go west so I just moved the seat over a little to the right and tucked a cable shifter between the seat and drivers door. So at this stage we get interrupted buy my son who starts pointing out that to go fast in this world we must consider aerodynamics. Silly old me, I just thought you added horsepower. Now we're talking of things like full length undertray, splitters and diffusers!! not to mention wings kaynards and a few other foreign words. Ok Ok hows this for a startClick to view attachment
returf
The big day arrives for me to take the 914 to start getting the cage done ( man this really makes me laugh as you will see ) I front up and all the students come out to meet and see what their next project may be. I explained the concept and what the end result should be (a GT2 car for a start ie something to compete with quite fast evo's and the like). I turned around for a moment and look what they had doneClick to view attachment

so I thought I had better chain myself to the motor to keep track of it Click to view attachment

but No!! that did'nt stop the little beggars

Oh well it's another day tomorrow. I wonder what that will bring??
returf
It's amazing what constitutes stripping a car ready for a cage means!!! I turn up the next day and caught the boys stealing the underseal!!

No I should'nt be so mean. These guys are doing a fabulous job to meet with their tutors standards. Everything has now been removed and the plan is to get the shell blasted

with the underseal gone the only small bit of rust can be measured for a plate to repair and strengthen. Not too bad for a 73 car really
returf
With the body ready it was delivered to one of my good friends that owns Supreme Blast and Paint in Palmerston North for the sandblasting. All the Work that the ucol boys did removing everything meant the body could be lifted by three people comfortably. Wouldn't it be great if you could magically strap the powerplant in and go racing with this weight!! Click to view attachment

While the body was getting blasted the boys had no rest with the paint getting stripped from the doors, bonnet and boot (well that's what we call each opening down here. but in the case of the 914 it should have been the boot and bonnet if we start from the front I suppose?

Now I've known Darryl the sandblaster for 50 years. We met at school and are still good friends. He races cars as well, in fact he races anything he touches so I suppose it shouldn't have been a surprise to get the Porsche back the very next morning all clean and etch primed. I reckon he looked at me and thought I better get it done quick, as he might run out of time and courage to pilot this damn thing. Anyway, thanks buddy Click to view attachment

When I had the car together before taking it to UCOL Motorsport, I sat in it with my race helmet on and decided we may have to lift the roof to get adequate clearance. Brent and I were tossing some ideas around and one was to explore the possibility of dropping the floor section under the drivers seat. The phone goes the next morning after the car came back from the blasters " I think we should make a new floor section right accross" I'll come and have a look I replied. " No I'm just letting you know we cut the floor out already" semi stunned silence from my end " Oh and you don't have to worry about the diagonal for the rollcage hitting the bulkhead either. Thats not there now as well" Click to view attachment

well I suppose the car is getting lighter!!

They will be calling me flintstone now
returf
Brent, the Tutor looks on admiring his handywork in the previous shot. The new floor is just sitting in place while we ponder making a new strengthening tunnel for the fuel and brake lines to go through. The new floor has allowed the movement of the seat closer to the centreline. This will help in the weight distribution and as one of my other clever mates pointed out. " once he gets his bum in the seat the c.g. will lower more than the 50mm you dropped the floor" cheeky sod!!
returf
Another view shows the drop section of the floor. there will be another flat sheet of alloy to go under this as a single piece from the from splitter[attachment=15510

returf
I had cut away the rear towers to allow the shocks to clear (remember the trailing arms have been extended ) So a set of strengthening boxes were made up to fill the gap and support the towers.

Thats going to be quite a rocket ship.
I've autocrossed a 500bhp LS6 powered 914, and I stood next to it while it was going 180mph on a dynojet.

I am definitely enjoying watching your progress!
Thanks for sharing.

Thanks Chris . While you're there and given your experience with racing 914',s do you have any starting point suggestions for the anti rollbar sizes?
Mike
Racer Chris
My 1.8L race car has a 32mm (1 1/4") hollow front bar.
I would think that's also appropriate for a car like yours.
If you have a limited slip differential a small rear bar is also a good idea.

Thanks Chris, that's a big help as I probably wouldn't have guessed at that big for the front.

things are moving along well over at the UCOL workshop so I thought I should contribute a little. My task was to exchange the rather original looking rubber trailing arm bushes for some nolathane onesClick to view attachment
returf
You can see by the last photo how much the weltmiester strengthening plates have shrunk!! My school teachers had the same problem with my socks too! funny that! Hopefully the nolathane will do the job. I see on some of the 914 sites there are some quite fancy poly bronze bushes available in the USA but alas, mention 914 down here and you get some funny looks .

What tires and what springs/shocks are you planning to install?
Will the car see much track time? or is it just for the street?
returf
Definitely only a track car now, I'm going to run full slicks, 285 wide on rear and 255 front on 18" rims x 10.5 and 9.5. The springs I have at the moment are 336lbs and 448lbs The mechanical leverage point at the rear is altered with lengthening of the rear attaching point of the shock on the swing arm (shock lays over a bit more ) and the front bottom arms are also longer. Coupled with these alterations, we are hoping to generate a large amount of downforce with the aero so it will probably be a bit of realtime R&D to get the right spring rates. My son tells me if we can't stop roll to a large degree we will wipe the skirts diffuser and splitter off the car.
Racer Chris
I thought it was full track prep with the undertray and such.
As far as I know I have the only front sway bar kit stiff enough for your application.
My car rolls approximately 3 degrees at the limit on Hoosier bias ply cantilever slicks.
But its lighter and has a little lower CG than your car will.
However, I can't stiffen the front bar any more until I re-install the rear bar.
It already lifts the front inside tire under some circumstances.

The motion ratio doesn't change all that much with the longer arms, but if I'm not mistaken, the front effective spring rate goes up and the rear goes down.
You'll need to keep the rear spring rate a little soft to maximize grip for acceleration, so the car doesn't turn around on you. I would be tempted to use the same springs front and rear at first.
returf
Not too much happened today I can take photos of, but reports of a new roof being rolled up are making me keen for another photo op. Will post as soon as possible
returf
Well I've been a bit loath to add this next post as I have to admit to a fail. I went to see how the roof was getting on a couple of days ago and the UCOL boys had been busy. The roof that was folded up incorporated a raised center section that had the makings of a real neat looking and functional air scoop for the intercooler intake. I gave Brent a hand to tweak it a little and stood back, squinted just a little to imagine it finished and opened a beer.Click to view attachment
Click to view attachment
The next thing on the discussion agenda was the venting arrangement of the radiator. "not too big, not too small, just right" were my instructions. I get home and am explaining to my son how good this is going to function when reality smacks me in the chops. What was I thinking!!, moving all that hot air from the radiator, catching at least a third of it and channeling it to my intercooler.
I phoned a very clever friend of mine that happens to be a design engineer and has worked in the aircraft industry. "Thank goodness you stopped" i think was the quote. He kindly explained to me how to use the hot energy from the radiator as a helper in our aero package and as polite as I've ever heard anyone tell me, how we had created unwanted drag and unwanted heat transfer to the project. Yes, double jeopardy ( or in my words Stuffed up")
At least the crossover headers will have a neighbour on the "wall of waste"
I finally broke the bad news to a fairly and justifiably unhappy camper last night with long gaps in the conversation. I'm sure he'll come around ( i wonder what that brown box at my door is, it seems to be ticking)

Now just a thought before it get's hung up on the wall of waste??

The boys have been modifying engine stands to form a rotisserie so the welds and other engineering work will be easier. This week should see a big push to get the cage more complete and all the body tie points welded in

A visit to the UCOL Workshop was in order this morning. The Guys have been busy on the roll cage, having made the main hoop and the two forward laterals

Click to view attachment

We ( that is the collective We, of me, myself and I ) have decided to run with the original roof structure, so have made the cage fit under the roofline. We ( being all the others and probably excluding the other "We" that was previously mentioned) may end up making a steel or composite roof later on in the project.

I think all the guys are really starting to get into the build

After a little trimming, the twin fan and shroud arrangement looks right at home. These should suck harder than ... I mean cool very efficiently. We are waiting for a bonnet vent to arrive before the final placement of the radiator mount

Click to view attachment

We will also be drawing air into the front of the radiator via a new hole in the front panel that will be sealed to the fibreglass front but first will have to fill the hole underneath where the air con radiator was.
