im about to get a vh45 but all i could find for my price range was a vh45 from a 96 q45. i have searched and heard people saying that 94 and 95 vh45's are the best and the only difference with the 96 is it doesnt have vtc. is there some reason people dont use 96 vh45's or are they just as good as the 94s and 95s. also it will be boosted.

Main reason people don't like the 96s is because of the VTC and the harness/electronics are different than the other years, which means the ECU can't really be tuned.

If you were going to use a standalone and you don't care about VTC, then a 96 engine might suit you well. I would also imagine you could convert a 96 engine to run on a 90-95 ECU, the sensors and whatnot all put out the same outputs and are otherwise the same.

Internally, they're not any different.

If I had a preference, I'd personally try and find a 90-92 engine and replace the chain guides and convert to S2 injectors. You gain the sodium filled exhaust valves, which is a nice feature on a boosted engine!

Im going to try to get the porsche cayenne intake to work instead on the spider intake which is why im wanting a 94 or 95 motor unless the siamese intake ports dont matter. If i could get a porsche intake to work on a 90-92 engine that would be sweet.

I don't think the Siamese intake ports would really matter, in terms of having them match up to the intake.. I can't think of another reason that the 94+ engine would work better than the early ones.

now i just need to find a 90-92 motor for around $700 which i cant seem to find anywhere.
