Default TB swap

Is there throttle body out there for the 92 */c engines? i know that the series 2 can use a N* or a ls1. could I use a N* or could i use a TB off a 94 or 95 bonne? and what else would i need to do to compensate for the higher flow.

You should just got for the whole 94-95 top swap. There should be some info on here on how to go about doing it.

You mean this one by irish?

The simple answer on the TB is no. The long answer is that there are things you can do to your existing TB. Search for TB or Throttle Body topics by me in the Performance and Brainstorming section. Or search on 'shaved throttle shaft' or similar terms.

In the long run, the TB bore is pretty well matched to the inlet of your SC. You won't gain much until you open that up, and the Gen2 M62 isn't efficient enough to have that pay off.

Start looking at KNOWN power-adding mods like valvetrain components, custom PCM, performance trans, etc to begin with. Unless you have a spare TB and a good machinist. If so, go for it now. Plenty of pics posted.

sorry for posting pretty much the same thing, in the first one i meant the */c. But thank you for your input. Im just looking for different ideas, i have a lot of misc parts just laying around for all my old cars, including a TB out of a 93 or 94 i forget witch but i dont have a good machinist around here anymore. I usually just take every thing apart and learn from them.

thanks again
