wheel horse power?

it's just an estimate, no one knows because no one's dyno'd before and after from stock to those modifications.

it doesn't really matter. they're primarily supporting modfications to other things.

pretty good gain for under $200. now i just have to find a 2.3 tb and maybe intake. that guy on ebay is useless, and no yards seem to have 2.3l engines around here.

[whiterider00]

does anyone know if the throttle body on the high output 2.3l (lg0), and low output (ld2) were both 56mm, or just the high output? theres a couple listed on ebay, but they dont specify h.o. or not. and when i asked the seller, all he said was its the 2.3l tb. im starting to hate ebay.

seems like some i would be interesting on doing

[whiterider00]

wow, so much help i dont know where to begin.

maybe someone can answer this question then. are the tbs from cars with automatic trans the same as manual trans? theres a tb listed from 2.3l engine on ebay that says itll interchange with tb in a grand am, achieva, and beretta with a manual trans.

im really hoping to get the throttle body around the same time as my cams and whatnot, but i cant seem to get a straight answer from anyone on ebay, or any sort of answer on here. ive searched online, wikipedia (for what its worth lol) and some on the forum, but cant really find if theres any difference in the engines/trans. any help is really appreciated.

well, searched more, and found 1 response in 1 thread on quad4forums stating that the h.o. and l.o. 2.3l have the same tb. however, thats not really enough for me to buy one, just to return it if it isnt what i want. i wouldnt think there would be a difference in tb size on the same general engine, but who knows. is there anyone who has proof that the low output and high output 2.3l engines share a 56mm tb?

hopefully i dont sound like an idiot asking this question over and over. i had assumed it was the same tb on both engines, but there really is no written proof that i could find.

All 2.3l quad 4 engines have the 56mm TB. no worries there. Do you have a junk yard near by?

[whiterider00]

a couple, but none have the tb. found a cpl on ebay for $40 shipped. one has a 60 day warranty too, so ill go with that.

If possible, make sure it comes off of a LG0 Quad Four. Those are the easiest to adapt to a 2.4 because all of the sensors, vac lines, and throttle cables line up almost perfectly with the stock 2.4 tb.
