Dubai944

In the UAE we were hp/weight classes which was fine except being FIA GT, engine swaps weren't possible anyway as the block had to have same number of cylinders and be from the same manufacturer as stock.

In Australia the only serious categories I could run a V8 in are capacity -weight based, so the top class for one category example which allows engines up to 6 litres has very few restrictions on engine mods but have to weigh at least 1100kg. 600+hp motors are the norm. From past experience I know that the 944 can be competitive with a bit less power if setup and driven well so getting over 500hp might make it worth it, but you are limited to 6 litres. What you describe might work if it is destroked enough.

6 liters is plenty to do the job.

Is the 1100kg with driver or without (2425lbs)?

No matter, you won't be under weight, though you could get it real close if you put it on a serious diet.

[QUOTE=Ruthie512;10000393]~$10,500 for a 400whp V8? That's a lot more than I expected./QUOTE]

Because it's a lot more than is required :-)


$11k will get you a destroked TI rodded LS3 with all the goodies making 550RWHP. Includes complete FI system, TB, Computer, Wiring harness, and Drive-by-wire gas pedal.

Actually the exact weight for the category is 1125kg including driver. My car is currently 1240kg including an 85 kg driver and 1/2 fuel so I could try and loose some of the 115kg (about 250 pounds).

Not sure how much the 16v engine weighs with the supercharger currently on it, but I imagine I would gain some weight with LS rather than loose it. I can't loose much more weight on the car without cutting the front and rear off. I might be able to loose 5kgs myself though if I cut down on my essential vitamin consumption

The thing is every time I look at it I figure I would probably end up slightly overweight, slightly underpowered and still be behind a lot of the cars on aero and suspension mods, so the right car would be more like what you are building at the moment, not a full bodied 944....but that type of work is out of the budget for me right now.

TonyG

The LSx is 430lbs approx + clutch assy. Pull out your engine. Weight the car. Then order the LSx engine combo that will put you just at the power for the HP/WT calcs.

okey, dokey, I'll just duck down to the garage and do that now..

All good info, thanks. I will store it away for future planning.

TonyG

Sorry

I meant that if you're going to go the V8 route... then pull the engine and weight the car. See where you're at and add about 450lbs to that, plus your weight (the driver). Then backwards calculate for your class, what's the max power you can have.

Then order the LSx engine that gives you that approximate power level.

No matter the power level... you can get the engine in about 2-3 weeks.

Duke the main factor for me was I could not run a reliable 310rwhp 2.5l without blowing headgaskets every season. That was a $2-3k recurring expense. The LS swap has a high initial buy-in, but then if you totally lunch a 400whp LS motor a good shortblock is only $1-2k away.

I'll be swapping in an entire Vette drivetrain to a 928 to kill 10 birds with one stone. The 944 chassis to get the Vette 6-speed and Torque tube takes some serious fabrication. We're working on a swap kit as we go.....

Ugh... Don't I know it...

There are a couple out there. Here is one that uses the transaxle:

I have been very close to selling my 951 engine and putting an I5 in, but I will probably wait until next winter. However, I would be doing the newer 20V 2.5L VW I5 from the Jetta/Rabbit. These motors are $500 in junkyards, 25% have forged cranks, make 400whp on stock internals with low boost, and are pretty much the best flowing VAG heads out there. A company in Vegas called Iroz Motorsports is working on a kit for swapping into Audi's. I will be working with him to come up with a kit for swapping into 944's. The motor is extremely compact since it uses the timing chain on the rear of the motor and all accessories are mounted on the side with an offset pulley drive. It's 5" shorter than an AAN engine (20.25" to the front of the pulley; only 2" longer than a 1.8T) so it would give you LOTS of room in the engine bay. Marc Swanson at EFI-Express is developing a plug-and-play VEMS ECU for it. Marc also has a bellhousing adapter that will work as he recently swapped a 1.8T into a 944 for a Lemons car.

The more I talk about it the more I want to do the swap now....

I've been looking at a 2.7 conversion based on the diesel block... I mean, go big or go home

Seriously, all the dyno curves I have been looking at suggest a rather peaky power delivery pretty much regardless of the turbo set up. Not sure this is worth the hassle compared with a 3.0 8V, at least for road use.

[quote=TonyG;10000406]That truly is a fantastic Deal Tony. But don't forget to include the cost of the conversion pieces too. I think it's currently $5K from Renegade? I don't know how much from the others.

95ONE

This is the main reason for me and so many others. The head gasket issue gets very old, very fast. But, the 3.0 block with the thicker deck shows hope.

I got to ride in a 2.6L tallblock UrQ with around 650whp a few weeks ago, it was insane to say the least. Also rode in a 2.3L (7A built block) that had a quick spool valve on a HTA 35R and that had a super smooth and useable power range.
