I honestly believe most people would be amazed at how little "SMOG" related components are on today's engines. They are pretty damn efficient.

Agreed I was hoping to pull off all sorts of smog equipment on my Boxster. Found a few things but not all that much. Even cats are pretty lightweight so I didnt gain too much wieght savings going straight pipes.

Brad,
A couple of observations/inputs/questions; Appears as though there's some room at the back of the motor. Is it possible to move the motor back a bit to give you some room in the front for a water pump or a remote drive water pump/AC? An LS2 water pump is about 2" shorter than the LS1; perhaps it might fit if you have the option to move the motor back a bit? Utilizing the stock type water pump would avoid a lot of custom remote drive stuff. I dont know how feasible it is to move the motor/trans back; are the drive flanges lined up with the hubs (front to back)? As for the height, the trans mounting would probably dictate that.
I suppose it's a bit early in the process to start asking a bunch of questions; sorry 'bout that. Untill you get the motor and trans mated together, it will be hard to get an exact position. At least the good news is that the damned thing seems to fit! Keep us abreast of your progress.

One of the problems with mounting a V8 longitudinal in the MR2 chassis is the ultrashort wheelbase of a Gen2 MR2 (biggest car of the 3 generations made) @ 94.5" Compare to a pantera at 98.4" (ford 315 cleveland small block, ford to ZF bellhousing, ZF transaxle).
I don't know what the wheelbase of the boxter is, but given your planned location for the LS1, I was wondering where your axle output flanges are on the transaxle, in relation to the rear wheel arches?
I am not sure of your adaptor plate thickness, so I am assuming its sandwhiched between the engine and trans.

No, no, no, please do not move the motor back as keeping the 50/50 is up most important.

Best you stick with something safe like a Miata or MR2. Wouldnt want you to hurt yourself. Move along and leave the "giving a shit" to us who are up for the challenge of putting 400 HP down effectively in the Box. (IMG:style_emoticons/default/happy11.gif)

I went to Marina yesterday expecting to see some black boxster boasting a TTOD, but he wasn't there. Did you send it down to Brad to have that V8 installed already?

I was delayed coming out of China then Narita airport - got last seat on a flight to Hawaii and then found another flight home. So I didnt get home until midnight Saturday. I was still asleep at 10 AM SUnday. But V8 is definitely on the menu if Brad figures out cost effective conversion.

I cannot move the engine back any further than what you see. The BoxsterS has BAD axle angles to begin with.. moving it back further would compound the already extreme axle angles they have from stock (IMG:style_emoticons/default/sad.gif)
The custom remote drive stuff: Mezier. They are just south of me in Escondido. They have an LS series electric pump with remote block off plates and a thermostat complete.

What drive angles do you anticipate having? THis was a problem I had to deal with on my own project. I found in my research that having more than 4 or 5 degrees will cause annoying vibration in the CV joints. I also found that having 0 degrees on a rear wheel drive car that does not have steering rear wheels is not desirable either, 1 to 3 degrees is the preferred angle. This keeps the vibration and wear down. A small angle also keeps the joints from creating dimples in the races.
A high angle creates vibration and excessive wear. CV joints have a lot of sliding friction, and tend to get hot. This is why special grease is required.

I needed some inspiration today.. and I was dropping off the BoxsterS for a roll cage.. thought I'd pop the hood off the current SCCA World Challenge car being finished up at the shop to snap some pics of how the belt arrangement works and to look at some "go fast" parts for the LS1 engine. This is a 750hp LS series engine. I would like to use this intake manifold, they cut it down right where the throttle body attaches.. this would allow me to run the throttle body under the stock Boxster engine lid (IMG:style_emoticons/default/clap56.gif)
Boxster V8 conversion !!!, Goto last few pages and see the LS1 being fit!!!
