1g Throttle Body Question

[john]

What years had the 60mm throttle body? Are they a direct replacement for a 2G? What are they worth when buying one ($)? Thanks, John.

60mm on the left 52 mm on the right.

The second generation Eclipse Turbo ('95-'99) comes with a smaller throttle body (TB) than on the earlier Eclipse Turbo. The 1G Eclipse Turbo ('91-'94) came with a 60mm TB plate, while the 2G Eclipse Turbo TB plate is 52mm in diameter. The TB on the 2G Turbo can be swapped for the larger 60 mm 1G Turbo TB with a minimum of modifications.

Thanks, I got confused when searching. Someone was selling their 90 as a 60mm and I thought it was the 91-94 that had it. What are they worth when purchasing?

Depends if it comes with a working FIAV and an ISC motor and all those goodies. Try and find one with a good FIAV otherwise youll have idle surge.

The 90 is a 60mm, but you don't want it. You will need to port out the intake manny opening a bit to make us of the extra 8mm also. I paid $100 for a 1G TB a long ass time ago, I don't know what they go for nowdays.
