Hey joe,

You could ask a couple of guys that live right here in town. Tom Egan has one. It's the blue one with 968 handles, mirrors and a custom CF RS spoiler, pictured on the Renegade website. You can contact him through the Alabama chapter PCA. He's the registrar. You can also talk to Robert Duff(944LT1 here on Rennlist). He has one that he did himself. Here's his website. V-8 conversion .

I have to agree with the previous post on supercharging... It's your parogative, but why spend in excess of $10k for converting to a V-8 reliably when you can have the best of all worlds by supercharging it. You will spend half the price, if that, as well as save weight, save that glorious Porsche engine, weight distribution and respect of purits RL'ers.

And as much as I would admit to LOVING a V8 powered 944, personally, I've always been a fan of driving forced induction cars myself. Blower whine is exotic to say the least!

Does anyone know how much power a blown S2 makes from a kit??

... a blown droptop is sounding like a plan for my future. Right next to the planned 914 project car, the 951 I'm getting in 4 days (first Porsche, by the way).... ok, well I'll stop there

I want to make a V8 mid-engine 944! Like that one that was in Turbo magazine a couple of years ago. Perfect to get the weight over the back wheels for accelration, that car did 9-sec. 1/4-mile runs or so. And the mid-engine would be perfect for handling on the track as well !!!

Sorry Danno, I guess it must fit if somebody has done it but it seems like you would have to be careful on the 3 - 4 shift as you might get your elbow into the belts!!??

Im just gonna join the camp in this thread of "Youre worried about maint, yet want to spend an easy $12,000USD for a swap?"

I imagine that $12k would pay for MANY years of maint....

And 41k miles isnt all that much for a 91 you know... On average thats 2 years driving. Im going to seattle to pick up my shiny 196k mile TURBO so what are you fretting about?

if youre s2 engine is running fine, why change? your car will handle very diffenitly unless the weight is the same, and not only that you will dramatically decrease the value, of your car, and if and when you sell, you will not get half of what its worth.

Supercharge ....

I am not a huge fan of the v-8 conversions on any car... Why? Its cheating .. You can make any V8 fast so that doesnt get my respect but a Turbo S2 that would get respect... Its just my nature to like the original engine in the car no matter how moddified it is if its orginal then its cooler

A few of you have mentioned the change in weight distribution. The renegade site claims that the actual weight distribution is less than a 1.5% change. The LT-1 does not weigh that much more than a 944 engine.

The following is a cut and paste from the RenegadeHybrids website. I am not trying to advertise for them just want to put the information out there about weight distribution.

"Contrary to popular opinion, the superb handling characteristics of the 944 are not decreased by the addition of the V-8 powerplant. In normally aspirated versions of the 944, the weight distribution changes less than two percent. In the turbo cars, the change is less than 1.5 percent. A typical characteristic of a stock 944 is a slight "push" or understeer under acceleration. We have found that with the added weight of the V-8 the "push" condition actually diminishes. Furthermore, the more manageable torque and predictable horsepower allows the driver to easily transfer weight from front to rear allowing for increased car control."

One thing Harry mentioned was resale, there have been a number of these on Ebay and to the best of my knowledge none of them have sold. I believe I watched one go up three times without so much as a bid. I think that if you are going to do it you better be prepared to have the car a long time or take a gigantic loss on it (which you do with almost any modified car).

OK, this has got me wondering. In other pro-conversion threads I have read, the claim is that the motors are the same weight. Are they the same, or are they 300lbs more? Has someone officially weighed all of this?

Your S2 must have been loaded with every accessory option for the difference to only be 300lbs between the two cars. Just from the size of the camaro verses the S2, I would guess the difference would be much, much more. Plus, from personal experience since I have owned a few (yes, including a Z28 and a Trans Am), I know GM is not known for building lightweight vehicles.

We oughtta get a truck weigh station to allow us to drive a a Z28 and a 944 onto a weigh scale and get the definitive answer............

I guess that's why he asked us not to ask why.

(Does that make sense?)

Personally, I think he just likes American V8s. Nothing the matter with that...in their place. I like 'em too, in American cars.

Also, I agree the value of the car will be greatly lessened. S2s may not be cosidered collectable yet, but I think the value of clean unmolested examples will start to rise eventually.

Hey Bigbass,

Why don't you just throw in a nice 602 Ci V8. Or maybe a Bugatti W 16 Quad turbo engine in there? Or even maybe, just glue two V12's engines, throw that baby in there and you'll have a great handling V-24 Engine'd 944. Sound good?

I found this on the 89 S2:

http://www.supercars.net/cars/1989@$Porsche@$944%20S2g.html

According to that site, the S2 curbweight is 2985lbs.

Your camaro is definetly lighter than I would have guessed, but I think the S2 is lighter than the quoted turbo weight of 3100-odd pounds.

Oh well, this is all moot anyway, it's all "apples to oranges" .
