Looking into a VH swap and I have a question....

[chaosdrifter06]

I'm looking into taking the path of the VH for my 91 300ZX. My question is how much power can I get just swapping it into the car with a ECU tune, exhaust, and cams? Feel free to correct me if I'm wrong. I know the VH45 comes around 278 horsepower stock and based from experience with American V8s, things such as exhaust systems and cold air intakes create significant gains. Is this the same for the DOHC 4.5?

with a rather bad missfire my vh45 put down 270whp on a dyno dynamics dyno at the wheels...with a good tune and no missfire i suspect over 300 is doable.

Is the torque at or over 300 as well on a good near stock tune? I hear the VH45 has excellent torque, from about 2k on...

its close and proly you could get that with a dynojet pull...but a bone stock ecu trim tune will not get you there.
