contorted fungus 0 Posted February 28, 2009 Report Share Posted February 28, 2009 just been thinking , if i use a turbo at low pressure would i need spacer gasket as the supercahrged boys dont seem to use one until they get to about 10 psi. aiming to possibly use a diesel turbo so as to get boost from about 2000 rpm and not 3-4000 rpm like most people get. just wanting to get some help with the setup to use as torque is more important than horsepower.

Bobtrude 0 Posted February 28, 2009 Report Share Posted February 28, 2009 There are a lot of treads in this forum regarding turboconverting. Look in the members rides and projects and garage engine tuning section and you could learn just abut everything there is to know . To answer your questions: If u want no or little lag you should use a small turbo, but you would have to use the right one. A garrett gt3071r would give u what u want. But buy the wrong one and it wont have the muscles to give u boost in the high revs. Your setup depends on how much u want to spend. Look around and make your own kit. If u want my recomandation I would go for a Kinetic turbokit, with the C2 software. Then u can change turbo, cams etc as u like and the chip will "adapt". Good luck, and remember: turboing your car WILL make you want more . Link to post Share on other sites
contorted fungus 0 Posted February 28, 2009 Author Report Share Posted February 28, 2009 i had read that the small turbo from the escort cosworth is good for little lag what rpm does the gt3071r start making full boost. would a spacer gasket be needed at 8 psi or will it be something i can add later Link to post Share on other sites
MaidenVR6 26 Posted February 28, 2009 Report Share Posted February 28, 2009 10psi is no problem without a spacer. Your VR6 engine is 2800ccm, not 2000ccm like a Cossie.So a cossie turbo will not work that well on the high revs. It will choke.Buy a cheap Garrett T series turbo with AT LEAST a AR70 exhaust house.

Bobtrude 0 Posted March 1, 2009 Report Share Posted March 1, 2009 Agreed. I think the gt3071r will start boosting at 2000ish and have full boost before 3000. cant remember but think thats what been said on the forum. . . . . Some people like to have a little lag, or the car might get "too aggressive". if that makes any sense . Link to post Share on other sites

Correct :-)Some people like to have a little lag' date=' or the car might get "too aggressive". if that makes any sense . [/quote']Also true :-)The way I see it, you get on average a 3 to 3500 rpm range with turbos (twin and compound turbocharging ignored for now). You can have that window of oppurtunity from 2500, but falls off past 5500, or you can have it kick in at 3500 and last until 7K.I know which I prefer. Having had the 3071 on mine, it was a pain in the arse, mainly because it's FWD and a turbo that spools that quickly not only potentially wrecks gearboxes, it also just spins the front wheels pretty much all the time in the wet....and yes, that's with an LSD and good tyres.You pays your money and takes your choices ;-) Link to post Share on other sites
