6.0 Litre V8 Ls2 into 944 Turbo

I have started a new thread on this, as I didnt want to hijack the other one, well more than I already have !
To all those who are interested in the whole V8 into 944 idea read on... to those that are rivet counters and think that a V8 in a 944 is the work of the devil.....well read on anyway!
We have been talking about this conversion for a couple of years now - basically its transplanting a 6.0 Litre LS2 V8 engine, as found in the Vauxhall Monaro into a 944 Turbo.
We bought a renegade hybrids "kit", threw half of it in the skip, and made the rest work. The problems were that of making it right hand drive, keeping the air con, keeping the PAS, and keeping a brake servo.
To that end, we used a scrap 944 turbo, and put the bits in. Its a non running mock up, but proves on the whole the conversion can be done - with a degree of sympathy to the car. We like to make things look like they should of been there!
So, down to the nitty gritty. The LS2 is a simple engine, and very capable. We have been tuning to various levels Vauxhall Monaros and Pontiac GTO (US derivative) since they were new. In terms of reliability, we tuned new cars
from 2004 - we have a lot of customers that have done in excess of 60k miles with no issues, and a few that have topped 100,000 miles, still with no issues.
Thats from mild tuning such as an exhaust and remap, to cam changes and forged internals with superchargers. Those who have been to see us will have seen a car park strewn with Monaros - we have seen and worked on well over two thirds of the cars imported.
So, reliability will not be an issue - in the 944 we would run a mild cam and expect around 450bhp. At that power level the engine will go on forever - reliability is key with a project like this .
We can introduce torque management into the PCM (ECU), meaning that the drivetrain can have less stress low down.
The 944 would retain the factory LSD gearbox and drivetrain, weight distribution is almost the same as the 944. with a very slight increase in weight to the front.
In terms of price, thats a tricky one. We would not do the first one on a customers car - there is always the possibility of a problem that cannot be solved, and we will not "develop" the project on someones car, with the inevitable outcome of keeping the car for months or years at a time.
We would supply the conversion in a car, as a finished MOT`d and taxed car. We would include the car in the price, it would be a 1989 ish M030 model, we have a few (three at present) available from stock. After we have done the first one, and proved the conversion as reliable and fun, we could then price for converting a customers car.
Finally the price, £19,995 will buy you a 1989 ish 944 Turbo, with a 6.0 Litre engine pushing 450 bhp. Thats the first one only. Finshed, with an MOT, road tax, inc vat. No risk on your part, if it doesnt work and cannot be done,
then thats that, but we are more than confident that it can be done, having done most of the development work already.

It will be an awesome car - on track or off!

Put my Mother on e-bay today. £19,995 reserve. [8|]

This is crying out to be done. Come on someone. Mark K, go on. You know you need to do this. [:D]
 
Do you think you will ever offer it as a kit Andy? Bring in your own 944, take home a 94LS2-8?. I'm of the opinion that the 944 is still a highly underated performance car, but that those 'in the know' tend to spend time and money on them, and keep them for a considerable length of time, 'improving' the car in stages, and monitoring the progress at each stage - that, for me, is what 944 ownership is all about. Unfortunately, I would also have thought that those 'outside of the know' would feel that £20k is pretty expensive, for a car of 80's design and engineering, albeit with a stonking great V8 and torque to pull a house! Good on you guys though, can't wait to see/hear/ride in one!

GROUP BUY???[:D]

- Edited as after re-reading my post I thought it came over a little negative, which is not at all what I wanted my post to feel. I just hope the 'kit' option might be available some day?
 
Andy, first off. WELL DONE THAT MAN....
I had heard that there was a "plan" afoot in your workshop, but nothing concrete was mentioned.
I too had looked into this conversion, BUT on a 968.
Im not a Porsche "purist" in the way it has to be a Porsche engine, + the fact the LS series of engines are almost the same weight as a 968/944 engine just helps ..The fact a LS engine produces a heathy amount of extra bhp is a big bonus...
There have been quite a few in the USA that have been done to some degree of success. But nobody had ventured into a RHD version.
The one big challenge i could see was the routing of the exhaust manifolds, am i correct.. To miss the steering shaft etc..
Anyway. I shelved the idea to hope one day in the not too distant future something might just happen, It looks like its about too...???????[:D][:D][:D][:D]
I hope somebody goes for this. then you can get down to producing a "kit" of parts for a conversion..
I think this could be "where some £££" might be.
Im of the same thoughts that a £20K 944 "turbo" is a lot of ££££££££££
But if a kit was supplied + the purchaser was to supply there own engine + car, then it could be viable. So long as the kit is reasonably priced...
Itd BLOW all those supercharged 968,s into the weeds....+ youd have great reliabilty....

Ill look forward to developments...Go for it...
 
Blimey.........that sounds like a plan [8D]

Having been impressed by one of those engines in a big heavy Monaro, I think it would make for a fantastically responsive package in the nimbler 944 shell. Well done on keeping the idea alive.

Did you take any pics of the mockup engine in the scrapper car? It would be interesting to see it in place even if it's not pretty, but please warn MarkK so he can look away first :ROFLMAO:

 
Whoosh!

I have to say, this is something I could be very interested in, but £20k for a 944 ... that's a LOT. Purely out of interest, how much would it cost to take a stock 944 turbo up to this sort of power figure? For that matter, how much do Monaros change hands for these days? I understand that development work isn't cheap, and this does include all the labour to do the conversion, but £20k puts you in some pretty tasty machinery on the second-hand market.

VERY interesting to know that it can be done tho'. Pictures would be great, particularly if they show the in-s and out-s of getting it to work with RHD. And if engines are readily available at the price pauly mentions (where do you get that figure from BTW pauly?) then I could easily see fitting one being a future project for me ...

Keep us posted andye. And thanks for proving it can be done!


Oli.
 
As much as some of us still want to achieve some big results out of the i4 motor, I also can see why this conversion
Would be very enticing. I know of someone that is building a Widebody version with an LS7 motor which should be
Fairly rapid!

To digress somewhat, I know that the Brake Booster presents a problem for RHD conversions but I seem to remember someone
On Rennlist changing this setup and that it would work for a RHD car. He built a pretty basic but effective looking mount.
I'll see if I can find a link or some pics.

Oh, and it's a 'HOLDEN' MONARO thanks very much. Born and bred in Australia. :)

 
I'm sure I'm not alone in not liking the idea of fitting a Vauxhall engine to our lovely Porsches. ("Holden" if you prefer).

Just to throw the proverbial spanner in the works- would it be possible to fit a Porsche engineered V8, such as the 400BHP unit out of the Cayenne/ Panamera?? (Assuming it is economical to purchase such an engine from a written off car).
 
A 928 V8 would suit me, although I dont know if its possible? I have seen a 948 but it didnt have a deal in common with a road car, so whilst it will fit, it might not be possible to make it 'work'.
 
Hi All,

The benefits of this conversion are that significant performance gains can be achieved with considerable (and proven) reliability for what is comparatively a modest cost.

Using a late V8 from a Cayenne would be prohibitively expensive because it would require total ground up development.

The LS1/LS2/LS7 engines offer bullet proof reliability, respond extremely well to tuning and have been proven to fit into the 944 Turbo engine bay. By utilising all the LS tuning experience, the risks of having to venture into territories unknown are removed.

There are known and documented issues with 3.x Turbo conversions and they can be very expensive to build and develop. Barry Hart has already explained the difficulties in using the 3.0 block for high performance turbo application.

A moderately tuned LS2 will make a very reliable 450bhp and will easily achieve 100,000+ miles with only basic servicing. All this makes its possible to achieve a genuine 450bhp 944 Turbo for a fixed and known cost with no surprises or frequent returns to the supplier (to correct issues and unaddressed development problems not identified during the project build).

What else will deliver 450bhp, 1380kg, 0-60 in 4 secs and 180+ mph top speed with the handling agility and balance of the original 944 Turbo? Add to that, what else can really achieve the same performance and dynamics for less than £20k?

It's a fabulous and exciting concept. [:)]

Regards,
Andrew
 
Andrew,,
Just do it.....Fabulous.
So whats wrong with fitting a Holden engine into a Porsche,,,,,,,,,, NOTHING...
So its not a Porsche engine, but seeing as a V8 Porsche engine wont actually fit then find the next best thing....Holden POWER.....[:D][:D][:D][:D]
At a Track day last year i chatted to a chap there that had fitted a LS engine into a TVR Cerbera. It was THE fastest car on track all day long + it sounded awsome....[:D][:D][:D][:D]

400bhp ++++ in a lighweight 944/968 chassis, that makes for one heck of a toy....

Andrew, just out of interest do you know what sort of MPG a Monaro is getting.???
 
Hi Dave,

I drove a 5.7 CV8 for 3 months and managed an average of 17 - 20 mpg. I could get 30mpg on a long run cruising at around 70mph (engine just ticking over). That car was not standard, hence a standard car should be more economical.

The latest LS3 engines (as found in the Corvette C6 and Vauxhall VXR8) are probably more fuel efficient.

Regards,
Andrew
 
Cheers Andrew.
I bet you had some FUN in the 3 months you had it.
How many rear tyes did you "go through".????[;)][:D][;)][:D]
 
a truly mouth watering prospect ...................

better lock my cheque book away !!

go for it Andy

ps would really enjoy having the conversation with my insurance company along the lines of "well I have just put a V8 in my car and the bhp has only doubled - please be gentle with me!"
 
I love this idea and if I ever end up with a spare £20k in my piggy bank I would certainly consider it. The LS2 weighs no more than the original engine and is very compact, the problems I understand from folk who have considered putting a 928 engine in a 944 are such things as size, complexity and the weight which would put out the balance of the car of course.

As for insurance when I was pondering this around 18 months ago I did enquire of A-Plan what the premium would be. Amazingly it was only around the £380 mark iirc for a 5000 miles pa policy. [:)]
 
This is fantastic news! I have been dreaming about this for many years and even went to visit the Renegade Hybrid guys when I was on a business trip to Las Vegas a few years back...I wrote it up for the club mag. Over the ensuing years things have got a bit nasty in the States with RH getting involved in arguments over ownership of the idea. Another group has now started producing fitting kits and downloadable 'how to do it' manuals...check out 944v8s.com.
The stumbling block for me has been the lack of technical expertise and the concern that the fitting kits were for LHD cars. So I'm really pleased that someone in the UK is offering this service. Have you a website where I can see more about what you do? Where are you based.? I have a 996 cab which might just go as collateral for financing this project!![:D]
 
It sounds great, not sure how long the gearbox will last but sod that. 450bhp would just be a starting point, I am sure Andy can tell you what kind of power you can get out of that engine. I remember being at a track day last year when a matt black RX7 was running round with I think a supercharged LS. It was rather fast!!
 
Hi Tom,

Gearbox longevity will not be an issue as the torque can be managed via the PCM to ensure that it is delivered in such a way to not overly stress the drive train components (drive shafts get the hardest time on the 944 Turbo along with 1st and 2nd gear). The 944 Turbo gear box is very strong and is equipped with case hardened 1st and 2nd gear components, hence will suit the application well.

A great deal of knowledge and experience has been accumulated programming the PCM module (ECU) enabling the car's performance and durability compromise to be optimised. The GM V8 small blocks (LS series) are very compact; incredibly strong and durable and capable of delivering incredible power and torque. 1000bhp has already been achieved with a twin turbo conversion (hence, there is even an upgrade path if 450bhp is not enough!).

Whilst the 944 Turbo is now well over 20 years old, it's hard to beat its chassis dynamics and handling (physics is physics whether it's the 80's or 2010!) Adding modern engine technology & modern engine management would considerably enhance what a great car the 944 Turbo still is. I believe it's potentially a very cost effective way of achieving 100,000+ miles of high performance 450bhp motoring (where track days would present little stress to the engine)!

Regards,
Andrew
 
This for me makes a lot of sense. I can remember seeing my race car body shell when it was bare metal with the cage welded in. The body shell is by far and away the best thing about these cars IMHO, as Andrew knows all to well the 944 chassis has proven itself for many many years in competitive racing all over the world. With correct preparation its as safe and strong as any tin top race car. Some of you may know Cieran Brewer or seen the horrific crash he had a couple of years back. It was about as big an impact as is it is possible to have on a UK race circuit. The fact he survived with only minor injuries is testament to how strong these cars are. IMHO the base is definitely there for a 400 or 500 Bhp monster.

Andrew do you reckon with one of these motors it would be possible to beat Michael Caine's Castle Combe lap record of 1:06.59 in a TVR Tuscan (highly modified saloons sports and gt), the production based record is 1:11.26 in an albeit I bet still modified Ferrari 360.
