Does anyone know if the Accel 58mm tb will work on all years?

85-92....I read somewhere that the Accel piece will work on all years by changing the throttle bracket. I have a chance to buy one for a good price The tb is from an 88 model my car is a 90. will it work? Im going to give Tim at LPE a call when they open. Just wondered if anybody knows.

Thanks,
Mike

I dont know for sure, but I do know the years are 85-88, and 89-92. Judging from that I'd say it wouldnt work. I dunno how difficult it is to change the throttle bracket.

85-88 tb works on 89-92 but not the other way around because of the later tb's lack of idle ports

To add to this, you will have to change the THROTTLE CABLE since they are different. I bought a like new 89-92 58MM ACCELL for $300 that I use on my car, and I also use an 89-92 TPI throttle cable. HTH's

Thanks for the help everyone!

88SS6SPEED...Thats what i was told this morning you did the reverse of what IM trying to do. Did you have any problems with the TV cable connection? would i need to swap that also?

BTW...Thanks for the tip on the Walbro pumps!

IM seriously thinking of buying a new one from summit. I dont know by the time i buy a new cable and swap them out.

Hey Mike, back when I had the 2004r in my car, I used the TV cable from a 90-92 tpi with 700r4. I think that the TV cables are the same, all the T.B. have the same TV cable hook-up connection. The 85-88 and 89-92 TPI throttle cables also hook-up the the GAS PEDAL the same way, the ONLY difference is the end that differs from 85-88 to 89-92 TPI. So, you should be fine once you get the correct cable for the particular T.B. No problems on the WALBRO PUMP info, glad to help a fellow car guy. SS-ya

88SS6SPEED...Thanks for clearing that up I think I finally understand the differences between the two.

I didnt end up getting the Accel unit though. I bought the BBK/Edelbrock one from Summit. IM hearing good and bad about them.
