Turbocharging the LT5 in 2015 - ZR-1 Net Registry Forums

rkreigh · 11-24-2015

I'm a definite turbo junky and although the LT5 isn't the best candidate I'd love to TT the car. fabricating the manifolds and plumbing is a big cost. I think modifying the 93-95 manifolds would help there.

study the LPE, SGC, Callaway, and Mallet TT LT5 and you can see good examples of the "plumbing"

the megasquirt makes a very good starting point.

although I would splice it into the wiring so the factory ECM is there to improve integration with the car.

I'd also recommend E85 and some nice head studs with the AES liners as I believe it would improve HG sealing or stretch the liners and groove the heads as LPE did (expensive and difficult!!)

the LT5 heads are very efficient but flow limited so turbos make sense.

I've been running around in a TT C5 (TTix kit) and I can tell you the torq from a good tt is a thing of joy.

I don't agree that it has to be a 50k build either. but it's not easy or cheap when you add up the parts and if you have to pay someone to fab up the pipes you are into a huge cost.

do some searches and I've posted up quite a bit on the TT Z subject.
