Help needed, adapting ITB's

[bbq1988]

Hey guys, im planning on adapting a set of ITB's from a Nissan SR20DET (N14 Gti-R) to my 3S-G, i will be measuring it up this weekend, im lacking on abit of the technical knolage of them (vacuum pressures and MAP sensor stuff) so if anyone could lend their brain i would apreciate the help.

Also the Size of the ITB's are 45mm (same as blacktop?)

TPS is gunna fun with the nissan ones, kinda silly really, when blacktop are the same size and its been done plenty of times.

Just creating yourself more headaches, search guff about ITB's on 4age 16v's. Myself and plenty of others have been over it plenty of times.

Also garagedori.com has good threads on it. Read all you can so you know what youre getting yourself into first.
