Does anyone know if i can take the single turbo from the 84-89 300zx and put it on a 93 model. Im thinking if the exhaust manifold can be interchangeable. Anyone try this or is it impossible lol ???

Anything's possible with an absurd amount of money. Your idea is completely and utterly retarded, though. Do some research. VG30ET in the Z31 is SOHC, you have DOHC, so the manifolds aren't bolt-on. Have you popped the hood on your 93 Z32? Have fun trying to pipe to a single turbo. And if you did, I'd hope you'd select a turbo larger than a T3... that'd be a whole lot of work for, ultimately, an overall loss in horsepower. Seriously... research. twinturbo.net is your friend.

and if you truly wanted to push through with this idea, neglecting Zlovers advice, they did offer a VG30DET but not in the states, so you could try and source those manifolds, otherwise go custom. but it will be expensive and not worth it.

And research will lead to an understanding that the VG30DETT was designed essentially as independent 1.5L inline 3 cylinders with a common crankshaft... the engine truly benefits from twin turbos. All the attempts to go single on the 300ZX have resulted in a horrific cost-to-horsepower ratio, and I've never seen a single one do more than 600-something rwhp, whereas there are several 1000+ rwhp Twin Turbos.

what i got from his OP was that he wanted to replace one of his two turbos with one from a z31. it's hard to tell though.

The turbo won't properly install into the Z32's exhaust system... you'd need custom downpipes, to say the least. There are dozens of aftermarket turbo options available for the Z32 that will allow you to reach any reasonable horsepower goal with no fabrication. Something tells me you have a long way to go before upgrading turbos though. (Not to mention, stock Z32 turbos have pushed Z32's to over 400rwhp, in recent times.)

zlover4life i think u helped me with my oil problem from a pre thread u may still know i have my motor out and replaced a few things fixing the problem. i just got done cleaning the engine bay by hand scrubing like crazy. sanding and its painted now . oh i have an N/A . i know i will want more power nothings unrealstic somewhere like 350-400rwhp but not from none turbo i gotta go tt

lol there's a bigger problem than the "will it bolt up" issue. the VG30DE doesn't take boost. the compression is just too high. boosting them typically yields disappointing results and short engine life. turbo swap or sell and buy are pretty much your only GOOD options. tons of other options, but none of them are good.

KasbeKZ, you're on a roll lately... except for the post in the "midwest members" thread.

To build your NA motor to handle turbos would be a drawn out waste of money. Other than pistons, the NA wrist pins are also considerably weaker, the oil jets on the inside of the block are positioned differently, the TT heads flow much more air, you'd need manifolds, you'd have to tap the block for oil, you'd need injectors, etc.

That's also ignoring the extremely different intake piping.

Get a TT front clip - comes with everything you need to put an TT motor into your NA. Then all you'd need is a TT fuel pump and control unit and other small bits (exhaust, for example).

By the way, given the amount of time and money it takes to do a TT swap, unless your chassis is in GREAT shape or you have a sentimental attachment to it, it generally makes more sense to buy a TT.
