What are your symptoms? I'm about to do a smoke test in the next month or two.

I read about Paige Baker's blue Z, and supposedly the destruction of her engine was caused by the cracked exhaust manifold. It sat for 2 years, and now it's a built beast like yours.

Well for starters I noticed a rich condition on bank 2. At first it wasn't that bad but now my plugs are fouled and you could hear an exhaust leak. I'm now trying to decide what to do next if I should possibly put a stock motor back in and sell the car or design my own turbo kit using a 6466 precision turbo.. Much time and money wasted kinda puts a bad taste in your mouth when even thinking about going with another turbo kit..

After talking with Charles and cjm, it appears the greddy manifolds have the same issue. So now I have a built motor and awesome fuel return system with No boost... lol

Not sure if the GTM manifolds are the same for DE/HR/VHR like I read the Greddys are, but this might be worth looking into.

Somebody has got to be able to make a set of GTM replicas here in the States. I bet there are a lot of Z/Gs with this same problem.

This is an inherent issue with Cast iron manifolds... Sucks bro...

Hey thanks for the help but at this point I really don't know if I want anything gtm on my car. I'm looking at a set of oem exhaust manifolds on ebay and use that instead of anymore cast..

I don't think anyone with a 370z has done a precision 6466 T4 with a 3" charge pipe on a built motor.

IMO, the route I'd like to take is to figure out how to retrofit a new pair of snails and manifolds to the existing kit. It's fine the way it is besides a few improvements here and there. It might be cheaper and less time consuming, and the result is still a nicely boosted car.

Other route is to part the entire kit and switch over to F.I. TT kit. That would be my other option if all else fails. I can't fund any of this unless I sell the house and live in a small box - not a problem since I'm still single with no kids haha.

It's a real shame because if it wasn't for the exhaust manifolds cracking its a very good kit..

Quick Google search points to some stainless steel custom turbo headers. Maybe get some quotes? I don't know much, nor am I able to pursue anything let alone keeping it maintained.

To be honest I would consider a bp kit over the FI mainly because of cost.. It would just be too hard to replicate the ones we have now with no guarantee it would work or anything..

COSMO

Not to mention the new z should be out next year and it is supposed to be forced induction so there's no telling what these guys are going to do who currently make turbo kits for our cars..
