If you don't port match it, it will do virtually nothing at all.

You should also have an aftermarket intake.

The B16 is probably a little big for that motor. There wont be any hp gains until after your rev limiter, and in the low RPM, you'll actually lose power, although throttle response may improve at partial throttle.


A B18A1 throttle body would be a better match, again, assuming you are going to port match the maifold and you have an aftermarket intake.

early b16's and b18a's throttle body is the same size as the d-series if i remember right, so depending if you got the early gen 58mm or the later 92-00 60mm tb, if you got the 58mm one its the same, if you got the 60mm one portmatch the manifold to the tb, and if you already have the basic bolt on's get a dyno tune and it will help....

Im looking at getting a LS 60 mm t.b to use on my performerX mani for a z6….
What mm size is the performerX the way it comes?
Is it hard to port match it? Let me know!

Is it simple for me to use my own sensors from my y8 t.b? thanks….

Wrong... D-series has 56mm

guess that will suffice... i myself use a 60mm tb. maybe i'll upgrade it to 62 or 65mm. i can even use a 70mm from a mustang, but i don't know if that would be no good for a n/a engine.

i just picked up the throttle body port matched the intake mani and put it on since my car is not tuned properly yet (soon to be tuned with crome) still running virgin p28 with the y5 so i cant really tell but when i get it tuned i will let you know if it made a difference once i get into high rpm right now i can really feel it picks up way faster but low rpm still is laggin because vtec engagment isnt intil 5500 and the vtec e motor doesnt like that :(

Get the 60mm gasket. It will bolt directly on if same OBD. No need for any modification.
MAP sensor doesn't need to be exchanged, they are the same.

Only thing different is that the FITV is present on OBD1 vehicles.
Shouldn't be a problem if your OBD2 I believe.
