So. A short outline to get the thread going:
I planned on building this motor for my mk4 gti. I got out of hand and things spiraled out of control. I sold the gti sans the engine and picked up a 1974 914. My dad has already built two teeners, so being familiar with the general ins and outs of the chassis really helped me (and will continue to) to plan things out. also, thanks dave. you rock bro.

Engine Build, bottom to top:
Goal: 500whp
06A 1.8t block (bored to 83mm with a TQ plate)
FSI stroker crank
Dowel pinned timing sprocket
stock mains
ARP main studs
ACL rod bearings
Brute con-rods from PagParts
wiseco stroker pistons
ARP head studs
AEB large port (early) head
Supertech valves (inconel and black nitride)
Cat gold valve springs
new oem lifters, new exhaust guides, new cam chain tensioner
Cat 3658 cams from QED
Pagparts Vbanded manifold
PTE5857. Billet, Ball bearing, Vbanded housing
tial 38mm wastegate
custom intake manifold (in the works)

Lugtronic ECU
ID1000cc injectors

Suspension and brakes:
Bilstein shocks
weltmeister springs in the rear
stock torsion bars up front
911 front spindles and 5lug
coleman 12in vented rotors front
girling 4piston brake calipers front(off an old volvo)

Chassis plans
914-gt steel flares
some old sweet race bumper with a big inlet for my radiator


tons of work to come. I think i'm off to a good start. the bay has been cut open and the rear reinforced to get ready for custom mounts. next stage is to really start cleaning things. I'll do the suspension after that, which will allow me to fit the engine/transmission in the correct location. cooling wont be a big deal. I could definitely use some input on intercooling.

so, now on to the pics. camera phon action is a must

Thoughts? I know they'll be a ton of those "why?" replies. In short: When building a 500hp motor, what better way to enjoy it than with a mid engine, RWD chassis?

I'm not gotta ask why, put an aba 16v turbo in one a bit ago. Amazing little power plants.

What are you thinking for transmission?
joedubs
012 from a passat 1.8t. Not sure what clutch and i havn't gotten a diff yet. Theres a guy on passatworld making 450whp through one of these transmission though. should be a fun little car with some 245's out back.

Joe,

I got my flywheel/clutch setup from ecstuning.com, and had the Quaiffe and trans drop shipped to Jim @ Shine racing for the install.$$$$$$$

Just read through the thread again:

I could definitely use some input on intercooling.

Yup, that's the problem every time. On my first build about 10 years ago, I used a turbo 1.8 8v w/ audi 5k internals. Total low buck engine, but it was effective. I hacked up the rear trunk much as you have so storing the targa was already out of the question. I ended up mounting an intercooler in the back of the trunk and cutting out the whole area between the rear taillights. I tried mounting it horizontal under the engine grill but it didn't drop temps very well there.

Charge temps were ok but not great. Only 15psi on boost though.

With the 16v, I simplified the exhaust which opened up some room. pipe off the turbo into a cherry bomb and straight back to the passenger side of the bumper with a supertrap. This opened up the whole area under the rear bumper for another intercooler. I ended up running 2 in series. One in the rear trunk and one behind a ventilated bumper. Better, but still not what I want.

I'm pretty sure the only way to do it right is a water to air IC with the water radiator up in the front trunk.

I think it will be awesome. The 901 tranny is only good to 350hp, then it will break. You should look into a 915 from a 911 if you want it to last. Also buy 930 axles or you will break CV's, especially after you add flairs and bigger tires.

yeah, as i said, i'm going with the 012. it'll be nice since 1) its been used up to 450+, 2) its cable shift, and 3) its hydro clutch.

which reminds me, what are you thinking for a master cylinder? I'm trying to figure something out that retains the stock pedal cluster. At this point it involves a bell crank :|
Jaxdream
You may want to try a Tilton pedal setup , a few guys that do the subby conversion use this as it simplifies a lot with brakes and clutch and they run a air to water IC with a front trunk mounted radiator as well . Those have tryed to do the rear setup but just couldn't get the temps down enough, the front cooling setup will yield the best results . Hate to see you bang your head trying to get the rear to do what you want, the areodynamics of the rear will not yield enough air flow for good cooling. Any ways , good luck with your conversion , it do look to be a good idea.

I kept the stock pedals and did exactly that; bellcrank with a Wilwood master for the hydraulic clutch.

One of your earlier posts is probably where I got the idea. The overriding theme I'm shooting for with the whole car is that it looks "normal" but REALLY isn't.

On the up side, it'll offset the weight of the alternator AND the driver.

ooooh its fine. I subscribe to the "overkill" factor. :-D
its the first time i've EVER assembled a motor. I went through the whole process of clearancing things, gapping the rings, installing pistons/rods, torquing everything etc. We'll see what happens when she fires up i guess.

Built myself an engine cradle. motor mounts will come next.

Inspiring. Wait, that's an engine stand and the bottom of a table saw isn't it? Git her done!

I'm thinking tomorrow I need to get started on my subframe...

I'm getting there. Going to figure out a way to hold the engine up level after i bolt the trans to it so that i can build my mounts. Tonight after work i'll build a wooden stand for the subframe instead of using buckets/jackstands and a worktable.
I'm happy with the progress so far.

He said he is using a passat tranny a few posts above yours....if you had read that...

For intercooling, search out Marty Snyder here...or MSDS.

He has a turbo car with a really decent intercooler design in a 914....it takes up most of the rear trunk.

So, since everything fits... its time for me to do some tweaks. Pulling it all back out tomorrow morning. Then its resto time.
Thoughts?
Andyrew
Awesome!!!! I plan on doing a 2.8 w/ the FWD trani as well!!!! Im thinking i'll start late summer!

I have a 1.8T in my A4 Audi quattro w/ the APR stage 3 package, Dyno'ed at 255AWHP on a puny GT28r. Those little motors are amazing!!!

FYI Im running the south bend stage 4 clutch and think it'll hold 300awhp pretty good. I've got the 16lb SPEC flywheel and LOVE it. But this is a daily driver. I havent heard good things about the fidanza flywheel, lots of chatter.



PS LOVE your engine cradle!

joedubs
Thanks for the comments.
I daily an a4 1.8t as well (though mine is an auto). thinking about doing a manual swap since volkswagen sucks at making auto's and my car drive like craaap.

I think im going to do a clutchnet 6puck sprung clutch with their lwfw. the price is right (a shade over 600 for the combo) and the 6puck should hold fine for my goals. I really think the trans is going to be my weak point.

Did some grinding last night. A lot of that BS sheet metal is gone from the engine bay. I ended up wiring wheeling a hole through my wheel well due to a thin spot in the hell hole. Looks like i'll need to do some hell hole repair (i didn't think it was that bad).
Andyrew
It is possible that your going to run into a weak point on the trani. You could Cryo treat the gears and such.

I've got a friend who has the quattro trani at 630awhp on the drag strip that holds just fine, but thats dispersing the load. The trani's are supposed to be the same internally, just different tail pieces.

I think that you might be OK because your just not going to hook up in 1st or 2nd. (I know thats my problem on my v8 conversion w/ 2nd and third... at 400lbs of tq).


Are you running the 4 or 6 trani?


Are you on Audizine? my user id is the same.
joedubs
its the 4trans.

joedubs on audizine and vortex. build thread is posted in the 1.8t tech forums on vortex. getting some good feedback over there.
joedubs
ohh man... here we go
i took my dads 911t out today for a spin. that little -6 loves to rev. I'm really starting to rethink the whole coolant and forced induction setup going into my teener. a -6 would be such a good time, and i'd probably destroy fewer transmissions. give me input!! its not too late to turn back!
Andyrew
NOO!! Those 1.8's are Godly!!! A properly setup turbo on a built engine and they just rev forever!! My STOCK BLOCK w/ my APR stage 3 revs to 7.2k all day long! The built heads that rev to 8.5 and are matched with a simliar size turbo as yours are just insane!

The plus side here is that parts will be WAY cheaper than the porsche products and way easier to find. All you have to do is keep your boost ~ 15psi and youll have plenty of power to run circles around your dads 911 and still have an amazing drive.

The good thing about these new turbo's and a fresh engine like this is with a good tune, the turbo's are extremely predictable! Unlike the older jurnal bearing turbo's that are hit and miss and could take forever to spool or could catch and bring out the tail, these new turbo's are just heavenly.

Go through with it. The end result will be amazing. I'd start for 350whp, then crank up the boost as needed..



Do a search for a4 HTA3076... That should show you the potential of these engine's.. Then keep in mind, your car will have 1200 less lbs and 10% less drivetrain loss (and 50% less traction..)
rohar
You can't punk out now, your progress is the only thing keeping me going at my current pace. Besides, Andrew has a major point. There's just nothing like hitting 7k rpm over and over and over again in these lightweight little beasties. If you're impressed with the 911, you will be amazed with a 1.8t 914.

ok ok.... we're back on track.

sorry for the lack of updates. I've been busy as hell between work and planning the wedding.

Been fiberglassing and bondo-ing. I've got 8 hours into the bodywork on ONE quarter (not including the metal work). i started fiberglass on a second fender but didnt add enough hardener (apparently) and it never hardened. i hate bodywork.
Andyrew
Fiberglass? Those are steel flares no?

Yes they are steel , see where he has tacked them to the steel body ???

Fiberglass reinforced body filler.... I'm using that for the first coat, just to ensure that there isn't any thick spots and to prevent the filler from shrinking as much as possible.

Its doubtful that the filler will see much stress, if any; so it may not be necessary... but ohh well. i only want to do it once.
joedubs
soooo.... i'm still around and still plugging away. winter should be fun with some time in the garage.

Flares are in place


Found some rot




looked good before

not so much (must have been 20ga sheet tacked in place)


so i cut it out




patch bent


drivers side cut out


patch




more progress soon.
joedubs
Still alive, nearly 1 year later :banghead:
I haven't gotten a ton done on the car....
My Dad, Brother in law, and I had someone ask us to redo his track car, and I couldn't turn down the opportunity to work on one of these:

It turned out pretty nice:


Not long after that I had my wedding to attend... so things were sorta hectic between last minute planning and then the honeymoon and such.
anyway, heres how the porsche currently sits. Things are calming down (though my wife convinced me to go back to school which means all my free/car time now has to get split for school work too). I'm hoping to dive back in and get things together. the suspension is set to go on (control arms are cleaned/painted, brakes are ready, I have new shocks/springs.) though I just need some little BS parts. I'd LIKE to have the car rolling with the motor bolted back in it sometime soon.

Martin Schneider had a really good turbo conversion kit he offered for 914s. You can contact him at MSDS Martin Schneider design systems, and he could tell you about it. He covered all of the bases with his kit

IDK about his wife but mine didn’t think I needed to spend money on my 914 for anything but maintenance and gas and spend the rest on her/us.

Joedubbs sold it to a guy in Philly and then I purchased it. I cut out the (poorly built) roll cage and I'll have the rear trunk bulkhead fixed. Dubbs cut out all the engine shelf so it's not really good for an air cooled engine so I'm putting in a 6 cylinder Subaru engine & Suby trans. I had made a deal with dubbs to trade the original bumper for the imsa bumper and steering wheel. I gave him the parts but he never gave me the bumper. Promised them to me for over 6 months but never delivered. It should be assembled next spring.
jockellis
Okay, it is next spring now. How’s it going?
