Engine is nearly complete, just rounding up the last little parts here and there, as it sits now:

B17a1
P30 OS pistons (11:1)
CTR Cams
ITR Intake Manifold
Megan 4-1 or DC 4-2-1 Header (these were just laying in my friend's garage, so I'm gonna use one of 'em cause I'm sure they're both better than a stock piece)
Everything else is stock, or unrelated
Will be tuned at Church here in SoCal


I have an obd1 b16a throttle body which could be used. Obviously it's small when compared to the ITR IM. Was on an engine which blew up and there were metal shavings in the IM and TB. Those are clean now but there's still metal in the FITV, I gotta see if that can be cleaned. I'd sorta like to ditch the FITV though so having a TB w/o one would be nice. If I use this TB I'll probably send it to Maxbore.


I also have the stock 92-93 GSR TB. This one is about 1-2mm smaller than the b16a piece listed above. I could send this TB to maxbore and it doesn't have the FITV, so that's good. But it does have some other BS on it (some throttle damper thing that came on G2 integras) which would be nice to ditch.


I'd be interested to see what everyone suggests for me. I was thinking maybe just a stock ITR piece? But I'm having trouble finding info about different throttle bodies. I need something stock, stock looking or at very very minimum CARB legal. Just looking to build a fun reliable motor for track days. I'm looking to focus on improving my driving before I worry about squeezing every last hp out of this (so I'm not looking for the most fancy, best-in-the-world parts, just want to make the smartest decisions given what I need). Any help would be greatly appreciated.

Thanks!

 

the stock 60mm will be fine upto about 190whp then a 62-64mm with a help a bit. that motor properly built can make 210+ on pump gas and be OEM reliable.

 

Thanks for the reply. Will having a larger throttle body do any harm? Or just not add anything at the moment? I don't really want to use either of the TB's I have now because of the accessories on them (I don't want any of that stuff). So I am trying to find a TB with MAP and TPS sensors (opposed to firewall mounted MAP)but no FITV and am unsure what my options are. I realize my swap isn't gonna make tons of power, so I don't NEED something large, but it seems the only TB's which satisfy my above wishes are also much larger than needed by my motor.
