Dannymik Posted September 27, 2003 Report Share Posted September 27, 2003 Anyone have any ideas from other vehicles or an aftermarket part for a throttle body on a 3100 SFI? Also how many mm's is the factory one? Thank you for your help! Quote Link to comment Share on other sites More sharing options...
Redfox340 Posted September 27, 2003 Report Share Posted September 27, 2003 52mm was the stock size. Any performance site for the 3100 including N-, J-, and W-Bodies will have bigger diameters. - Erik Quote Link to comment Share on other sites More sharing options...

Redfox340 Posted September 27, 2003 Report Share Posted September 27, 2003 So these would bolt right on with no problems? Thanks I don't see it as a problem, since GM loves interchangability. But, there may be a question of bolt-up if you change Generations of engine / intakes. Check will Robby, Vegeta or anyone who's done a TB update. - Erik Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted September 27, 2003 Report Share Posted September 27, 2003 Yeah, you would have to get one for a 3100. The 3.1L TB is different than the 3100, yet the same size. I know of a place that makes 62mm TBs for a 3.1L, but I dont know any for 3100, but any N-body site or something like that prolly has them Robby Quote Link to comment Share on other sites More sharing options...
The Burning Rom Posted September 27, 2003 Report Share Posted September 27, 2003 http://www3.sympatico.ca/fjpeters/throttlebodies.htm They have a 62mm TB for the 3100. I'm ordering a 62mm for my 3.1 from there. Their TBs are better because they are new machined throttle bodies. Not bored like RSM's. Quote Link to comment Share on other sites More sharing options...
god910 Posted September 27, 2003 Report Share Posted September 27, 2003 I just emailed them and asked them if they could machine me one w/ N2OHHH ports in it. If so, Black Sunshine might just be getting a bigger mouth. Quote Link to comment Share on other sites More sharing options...
The Burning Rom Posted September 27, 2003 Report Share Posted September 27, 2003 Problem with TGP applications is that the inlet on FDP's throttle body is round. The end of the IC to TB pipe on the TGP is oval shaped, and made of steel. So it's not like the pipe will be able to "form" itself to the round TB I am going to either machine an oval inlet for the one I'm getting...or chop up a stocker and modify the oval inlet for the FDP TB. The good thing about the FDP TB is that the inlet is just screwed on. You can remove it and put whatever you want on there. BTW, I already talked with Franz at FDP about this issue.

Did they bore it out at all? All they say is that it was ported and polished. :? Quote Link to comment Share on other sites More sharing options...
kfahn Posted September 27, 2003 Report Share Posted September 27, 2003 very true...i sent an e-mail asking for details about the machining of the TB. Quote Link to comment Share on other sites More sharing options...
nerfbars Posted September 28, 2003 Report Share Posted September 28, 2003 If they didnt put a bigger throttle plate in it then there not really increasing air flow mass by much, maybe just speeding up the flow a tiny bit. I like the idea of the machined 62mm throttle body better. I wonder if the machined one still has the ports for the coolant lines? Quote Link to comment Share on other sites More sharing options...

It says that in their description....and I don't see any fittings in the picture You don't need those anyway...unless of course you drive your car a lot in VERY cold temps.

nerfbars Posted September 29, 2003 Report Share Posted September 29, 2003 Define cold temperatures, I do drive my Cutllass all winter long. Has anyone done the bypass mod and driven in 0 degree weather a lot? Quote Link to comment Share on other sites More sharing options...
