EJ255 into a Porsche Boxster

kcpaz · 08-31-2010, 04:03 AM

So this is the first step. Engine is bolted to the 6 speed transaxle via custom adapter plate. Next is fabricating motor mounts and other operating systems.

The donor car is a 2000 Boxster S that I purchased with a blown motor. The plan is to build this car to compete in NASA's TTS and ST2 classes, with the primary goal of testing the conversions for reliability prior to offering them to the general public.

The goal is for the car to weigh no more than 2300lbs wet without driver, and have a power-to-weight ratio of no less than 8.7:1 in order to fit into the designated classes.

The body will have flared quarter panels and fenders to accomidate 315mm tires out back, and 275mm tires in front...

Rear fender flares are also bonded on...

New body work in front too...

Test fit the engine today to see how it fits. It's almost like it was meant to be. It almost looks like the turbo might be able to fit in the stock location on the engine, although that's not what I will be doing on this car. There is almost 6 inches between the crank pulley and the engine bulkhead which is WAY more than the stock M96 engine.
Next is motor mount fabrication.

kcpaz · 08-31-2010, 04:08 AM

Prototype motor mount/cradle is finished. It mounts using factory hardware locations, and requires no chassis modification or welding. The bottom of the cradle also acts as a skid plate of sorts since the oil pan sits about a half inch lower than the stock oil pan.

kcpaz · 08-31-2010, 04:10 AM

Turbo and supporting pieces. The turbo is a twin scroll GT3076R

*sprut*. Why the choice of a Subaru mill? Cost/aftermarket?

The Subaru motors are FAR SUPERIOR to the M96 Porsche engines in every way. The Subaru engines are lighter, make more power, are cheaper to maintain, cheaper to buy, more reliable, and more compact.

Because a reliable M96 rebuild and turbo setup would cost almost $40k.

This man knows what he's talking about. Plus, in the end, you would still be stuck with a heavy, bulky, and complicated M96 that was NEVER intended to be boosted.

Jake Raby can build you a reliable, fully forged, low compression, updated IMS, nickisil cylinder liner engine ready for boost for around 25k. TPS makes a turbo kit, but it's another 15k.

I agree that this is a great option, there are quite a few 914s with Suby power running around. You may be able to source some parts from Renegade. How much do you think you will end up spending with this set up? They only thing that makes a race prepped M96 attractive is being able to keep stock ECU.

There is even a Porcshe technician trying to put a LS3 in a Boxster.

That is a loaded question. A lot of it depends on how the kit is built. I'll have more defined figures after I finish the first test car and the first street version of the kit

Yeah I know Brad. Last time I talked to him, he said he was getting close but is trying to keep everythying a secret until it's done.

BTW, this isn't my first Subie Powered Porsche Conversion...
