vortech supercharing a griffith 500

[ihatesissycars]

The chap who bought my itb's knows someone in europe somewhere that is fitting an ls2 to a griff. He said its going a treat! Corvette sump fits perfectly, the front of engine sits behind the crossmember no problem. Really all you need is to make your own engine and gearbox mounts and get your prop lengthend by something like 3" and it will go in with out further mods. The only bummer is that you'll need to make your own manifolds which if thats the only tricky bit then its an easy install. After its in just plumb the furl and cooling systems in to the original griff stuff then thrash away!

Hi lads, thanks for all the advice, you've effectively told me that the best way to get 450-500 reliable and relatively cheap bhp from a supercharged rv8 is to fit an ls7 chevvy..... So as I'm a very accomodating type of bloke, that's what I'm gonna do. I'll spend the summer with the 5 litre and make my winter project the conversion to the 7litre, so I'll be in touch. I'll just have to concentrate on supercharging the 911 along with the flat nose and lambo doors......

GOOD MAN!!!!!!!

You have to keep us updated on this one!

[georgiex]

Don't worry, you're not getting off the hook that lightly, I'll be asking where to put this n buy that.....

[ihatesissycars]

Awe feck! No worried, i'm sure the we can come up with an answer for any questions or probs you come accross.

Wise choice, although I doubts its as easy as some suggest....especially the trans ??

If sticking with a std LS1/6/2 motor, then Id say the T5 could probably survive for quite a while.
It would certainly be the easiest and cheapest way to begin the conversion.

Then when it breaks, look for upgrades ( ie Tremec TKO or T56, although the latter is huge )

Check here. Jellison, and I think a couple of other members have don the LSx zcnversion already in their Chimeras.

I think Jellison is also registered on this forum.

I saw a website of a Brit guy who has put a 500hp V8 Chubby in a Seight kitcar, and took it to tour the USA. Talk about overkill, I bet he was brickin' it when dicing with them big semis on the freeway, bit of Fast and Furious 'between the wheels' stuff.

You really need to look into this a lot more closely. Whilst I like my chevy's I realise there isn't anything like a free lunch. A chevy ls7 conversion and gearbox plus all the rest will cost you a lot more then tuning your rover even if you do a full rebuild on it.

That said, once you've invested in the new brand and spent loads it has more potential.

From another tvr owner fitting an ls2.

"The LS2 (6000cc) is 100mm lower than the RV8, giving ample place for a
compressor on its top... Normal crate is with Corwette alusump, a
perfect fit in the frame.
The width is the same as you see from the photo, the block itself is
longer, but the coolantpump and balancerwheel is a much shorter build
leaving the removable crossmember untouched. The Engine/gearbox (TKO600)
is shorter than the old one, I had to order a new driveshaft 80mm longer
than the old one! 1330 racing crosses and 3" tube - bulletproof!

An LS7 (7000cc)will be even better, (adding $10k to the total budget),
but I would not stand a chance having it accepted by the authorities
her. Also you will not find place for the rather big oiltank following
the drysump system. In the trunk perhaps..
A 3" exhaust system will also be a problematic fit, remember the
original and sports-exhaust for our 500's are 2" in the silencer area

But working the solutions around this would be fab!

The LS2 can be cammed another 100 hp - without even touching the GM
engine controller!! Documentet by Hot Rod mag

And now you have the LS3 entering the market, identical to the LS2 but
6200cc and 435ps.

I would stay clear of the older packs as the LS1/6 (5700cc) to have the
advantages of the newest tech.

Theres no place for the A/C under the hood whatever type you choose.
Eventually a smaller alternator - I don't know. We are just above
freezing her, new fallen snow yesterday, so I don't care "

I thought he used a t56 but its actually a TKO but so far its a bolt in job with no chassis mods, the only really time consuming thing being the exhausts.

While an LS7 might be a little bling, IMO its a total waste of money.


You could build a nice 427 using the "older tech" parts for less money, and make the same power, if not more.

The key is value for money. If I could make say 600bhp n/a using old tech parts, for less money than a totally standard LS7....

Why would anyone in their right mind spend the extra on a standard LS7 ?


When it comes to LSx stuff, the list of goodies out there is almost endless. You dont need to buy the most expensive, newest stuff, to go fast.

[HairbearTE]

100% right there Stevie. The best deal around at the mo has to be the 440hp LS2 crate with the victor intake for around $5500, nearly a third of what the LS7 costs. spend $8k on it and you're gonna be getting more power for your $13.5k than the LS7 for sure. I dont think we should knock the LS7 though, Ti rods (albeit not the finest Ti rods) and CNC heads on a road car has to be a good thing in my opinion. The new Z06 was quite a bold step construction and materials wise for GM and thats good to see. Now if they can only ditch the fibreglass leaf springs they might really be onto something!

[stevieturbo]

Not really...no sense buying a crate motor, then throwing half the bits away.


Just buy a proper motor from the start, with all the right bits.
