Guest Azel Posted May 10, 2002 Share Posted May 10, 2002 Hey, finally my area of expertise! This swap has been done before in a 240Z. It was done in Australia, Owen has some pics of the swap in a magazine somewhere, maybe you can ask him to scan them? Didn't know the details of the project but the motor was running a T78 single turbo. I have a Q45. According to the techs, the heads on the very first '90 Q45 were the best and the '94 had the best block. Don't know why, but that's what I've been told. 5 PSI is conservative and should be ok on the stock compression, but remember the VH45DE's pistons are light-duty cast and in any case of detonation and you'll need new forged pistons, rods and most likely a new block as the pistons will probably fly right through the block. Also, the rod bolts are 8mm which isn't really suitable for a forced-induction application. Personally, if I were to do this swap, I'd get custom pistons, rods and higher pressure valve springs on the exhaust side. This way you could safely run up to 10PSI. But before you proceed with forced-induction, this motor can make 315 hp, 330 lb.ft with nothing more than exhaust and Jim Wolf ECU. It's a great engine, but there might be easier, cheaper alternativees but if you are really serious about this swap, then I wish you the best of luck.

Guest Aaron Posted May 11, 2002 Share Posted May 11, 2002 OK, I have been planning my car for several months, and due to taking over most of my grandparents farm, it looks like it will be next year before I get to start on the car. The car is an 82 ZXT. I want to do something unique and different, so I have considered putting a Infiniti 4.5L V8 in the car. The 290 HP that that motor put out just is not enough for me so I was thinking about putting a turbo on it. The engine is a 4 valve, dual overhead cam all aluminum engine. Online, I have seen it supercharged and pushing 600hp, but the kit for that is like $7000. My questions are: 1) What would need to fabbed (I am not scared of fabrication) for a single turbo setup? Header, exhaust, intake/intercooler plumbing, etc. 2) The engine comes factory with 10:1 compression. I was thinking maybe 5 PSI boost. Is this reasonable?. Will a lower compression be required. 3) What kind of power would this combo put out? My car will be a fair weather driver/toy. I am not planning any serious racing, but would love to drive it accross country, so if my setup will not be reliable, I will not do it. Thanks in advance.
