#1 I've got to agree with some of the other posters about going bigger. The 3.6 and 3.8L engines have just about the same foot print as the 2.5 and 2.7L, but MUCH more power. This sounds like a very expensive project. I personally would go with a bigger engine to get the most bang for your buck.

Have you considered going air cooled instead of the newer water cooled engines? The last generation of air cooled engines are from the 993 and they were pretty powerful too, more so than the modern 2.5 and 2.7L. I'm just thinking that it might help to simplify things quite a bit to not have to worry about front mount radiators (although an oil cooler might be required). Older 911 engines are even simpler and would be an easier install. I'm not sure how much power the 901 and 915 transmissions from the MR Porsche 914 would take, but you can probably mate up a lot of the 911 engines to those transmissions for the MR layout.

First of all, good luck w/ your project! Its sounds very cool. Kinda like a german SHOgun (you remember that one don't you? Its a Ford Festiva w/ a SHO Yamaha v6 mounted in back)

I believe Suncoast is having a sale on engines w/ no core needed. You could pick up one of these, get your boxster (w/ a blown engine or rms leak etc. ) and not have to find a crashed one. You could then sell off all the rest of the pieces or ???

Take lots of pics and document everything!!!

I got your back on this one...


Perhaps the next project will be the infamous construction of a silk purse from the sow's ear...

I still think this is the way to go--968 Turbo S engine

http://968turbo.homestead.com/Number3.html




This was the "mystery car". I spoke to Gerd Schmid at the Porsche racing department and he told me the car was in England. I searched for two years and finally Gary Hill gave me a lead and sure enough, it was in England. The car is black with pink and purple blobs and is affectionately known as "Bubbles". It was purchased new in March of 1994 and raced in the 1994 BPR series, driven by Erik Hendriksen and Justin Bell.



The car is currently being maintained by Russell Lewis, owner of RSR Engineering (Porsche garage) and contributor to "911 & Porsche World" magazine. Russell tells me that the car has 7000 km on it and has never been crashed. Other reliable sources indicate that the car has had many "incidents" and blown engines. Another source once told me that the car was totalled and all that was left were parts, but we know this is not true. So maybe this car is still a bit of a mystery!



Russell says the car has all the endurance mods including 120 litre fuel tank, air jacks, leightweight parts and engine output increased to 440 bhp!

If he wants neck snapping acceleration and money isn't an object why not convert to electric? At least after the substantial outlay the car would be inexpensive to operate... Love the RS engine, the specs are eye popping, however, I'd rather have said engine in the 968RS.

Woooo

Nice turnout.

I feel bad for those who are interested in such things as silk purses and sold out shelby!

Anyway, thanks for the feedback about the larger displacement engine. How close is the sizing on this? I know that VW's VR6 engines had the same size block in the 2.8 and 2.9L models, but how close can these larger ones be? Keep in mind that this car weighs pretty close to nothing and it does need to stay on the road, so I'm not looking for insane power. Before I decided on this flat 6 route I had almost purchased an old 928 with an 8 cylinder engine just to be unreasonable. Then I decided smaller is better.

Another thing I was worried about with the larger engines is, it needs to be MR and not RR to preserve handling, and I need to keep the engine in front of the rear axle but behind the firewall.

The most expensive part of this (sadly) is purchasing the Porsche parts for it. The body modifications and the installation of the motor should come out to be well less than the price of the engine and transmission. I am drawing up all the plans for the modifications to the frame on AutoCAD 2009, which should make things reasonably precise. I know I should buy the engine and tranny I need first so...

What engine do you feel I should use?
