Turbo charging a S6

[thainy77]

I can't see my engine lasting too much longer without a top end re-build and when that happens i think i would prefer a total re-build.

Has anyone done it? what do you all think the pro's and con's would be? Lees strain on the engine but heat from the turbo etc. And what would be the difference from super charging it? i'm a bit of a car mechanic numpty so any advice would be appreciated. I'd like to go in eyes wide open if i went this route.

Wilder were talking about doing a turbocharged SP6 but they've been quiet for a while, but if you ask phil james (bosscerbera on here) what's happening with the wilder turbo installs I'm sure he'd be happy to talk it over with you.

If you are hell bent on going down the turbo route then I concur with Jools, however I just can't imagine how anyone will get the 2 turbos mounted and manage to suitably negate the subsequent heat radiation. The engine is cantered over towards the chassis on the side of the exhaust manifolds and there is little room to start with. I had to get my headers ceramic coated and then build in aluminium heat shields to protect the heater matrix, chassis rails, engine mount, bell housing and the gearbox. That's with using a centri blower. The turbo's could be lagged but that will need to be maintained and especially if the car is used during inclement weather. Wilder may have all this well planned out and accounted for so do drop Bosscerb a line.

The supercharged option? From my experience there is only one company out there that have succesfully already done it and are almost finished doing another. Then there is another company I understand have an installation under develpment with at least one car (both the above car owners are PHer's). So may I suggest you also contact STR8-Six and Racing Green to discuss the Supercharger option.
But one thing is for sure, either route will NOT be a cheap upgrade to get the power. And it also costs a lot further if you take steps towards preserving your investment from melt down.

Good luck

Thanks for the info guys. The post above was the sort of thing i was after, i know there would be an issue with heat and the cost would also be an issue but if i did do this i would have it all worked out prior to starting the project with my garage.

Has anybody else got some more pro's and con's?

Thanks again.

If the car really needs a re-build, get it re-built to the standard spec or replace whatever it actually 'needs' then sell it on and don't make the mistake (like i did) of throwing money at it to make it faster. It will never be as good as you'd like it to be. I bought a Noble, for a 1/3 of what i spent on the T350 I upgraded the intercooler and exhaust, re-mapped it and now it has got roughly 95bhp and 100lb/ft of torque more than my TVR had. Also handles like a sports car should (just my experience and opinion)

Why would he want to sell it on after the engine rebuild? They're seldom as good as we'd like them to be which is what drives owners to modify and upgrade to achieve the improvements they need/want. Doesn't necessarily mean he wants to desert TVR.

My thoughts fwiw would be to build for boost by fitting a nice set of pistons and rings and some decent rod bolts. A lot of other stuff could remain stock unless they are known to be weak in which case you'd change them anyway. So this part of the build needn't cost much over the normal expected build costs.

As for turbo's, I'd cast a single manifold and probably run 1 or 2 turbo's off it but space being the issue it may be easier to run a single front mounted turbo. A decent single turbo is getting on for £1200 but that's a lot les then a S/C. You would need an aftermarket mappable ecu and spend some time thinking about heat management, ie bigger coolant system and radiator, more airflow, good heat insulation/shielding/air gaps. All common sense stuff but not always applied. It's a do'able project and needn't cost the earth.

He mentioned the engine may need re-built and talks about doing upgrades, my opinion on it (after owning one for 2+1/2 years) is not to waste money trying to find extra power or improve it, either drive and enjoy it the way it is or sell and try something different.

Errr, I could be misunderstanding, but doesn't this thread http://www.pistonheads.com/gassing/topic.asp?h=0&a... imply you're looking into another large upgrade yourself?

I can see both points and am definately going in to this with my eyes wide open. It may not happen for a few months yet, who knows, but i will definately be keeping the TVR.

I see it as more of a hobby, all be it an expensive one, and what i don't spend on the car would only get wasted on rubbish anyway.

I will be getting with my indy within the next few weeks to see what they come up with regards to the turbo issues.

Nope i was just bored and curious if it had been done as the new m600 due out is going to be a v8. My car is fast enough as it is with 475 ponies
