throttle body upgrade

[JC-GSX]

Is it possible to use the 1g throttle body with 2 vacuum lines on the top and 2 on the side or only the one with 4 lines on the top. Thanks for the help.

The 1st one you refer to(2 on top & 2 on th side) SUCKS its from a 90. DONOT get it. Get the 91-up(4 on top).

True. Only use 91 and up.

i have a jdm throttle body it only has 1 line on it. do i keep that one on or do i put the throttle body on there from a early 92. i think that one has 4 or 5 thanx

what happens if I use the 90 throttle body?

supposedly it wont work, the vacuum lines wont work but if yer like me and removed all the emissions crap then I dont see how it would matter.. I have a 92 on my car though just to be safe

so should i use the jdm one with 1 line or should i go with the 92 with 4 or 5

91-94 with the 4 ports on top if what a 2g person would upgrade to.. the 1st gen guys dont need to upgrade unless your pushing some serious power

well i bought a jdm motor i am going for low 12s. the throttle body that came on the motor has 1 line. i really dont care about emissions. i have the old motor witch was out of a 91. should i swap the 91 intake with the jdm throttle body because it dosent have all the emissions on it. or take the 91 throttle body and intake and just put the whole thing on my motor. what do you think would be better. thanx
