1G Throttle Body Mod

[Knaackers]

I was wondering if there is such a thing has a 1g Throttle body swap on a 2G Eclipse GST? If so, how much horse or a differnece is it? and where is the best place to find one? What year?

Does it have to be from a Eclipse or talon? Does it matter if its from a turbo engine or not? does it matter if its a Automatic one or Manuel?

It has to be from a '91-'94 turbo DSM.. not the earlier ('89 to early '91). Whether it's an automatic or manual doesn't matter.

Turbo Eclipse/Talon/Laser are all the same.

 

[Knaackers]

you know which one would be cheaper perhaps?

 

[Turbocharged]

They would both cost the same. They are the exact same throttle bodys on mechanically identical cars. I got mine off the trader for $45.

Would there be any reason to do this mod to a 1990? I mean to swap out the 90 TB with a 91-94. Are they all the same size... and the 90 isn't as compatible for the swap or what? Just wondering. Thanks.

I was talking about 91-94 turbo DSMs btw

 

[Turbocharged]

91-94 is 60 mm
95-99 is 52 mm
And I thought I remember reading that the 90-91 TB was 58 mm. I dont remember where I read this so someone correct me if im wrong.

Just an update for anyone who is interested. I found out the hard way that a 91'-94' Throttle Body will NOT fit on a 1990 DSM. If anyone can prove me wrong please do so.

Actually the TB fits fine, but the TPS is different and will not fit with the 1990 Fuel Rail (they bump into eachother so the TB can't seal to the Intake manifold). Using the 1990 TPS on the 91'-94' Throttle Body is not an option either.

Also, from what I can tell the 1990 TB is only slightly smaller than the 91'-94' Throttle Body... it looks like 60mm to me, but it could be only like 59mm or so.

Yeah... the 1990 TPS is actually smaller than the 91'-94' TPS... so putting a 1990 TB on a 1992 car wouldn't be a problem. But my situation is the reverse... I'm trying to put a 91'-94' TB on a 1990 car... and for some reason the bigger 91'-94' TPS doesn't allow the TB to fit. But from your other post it looks like you just replaced the o-rings on the 1990 TB and got it to seal? Let me know.

Yep... that would be me. Well it was me. The car's sold now.
