Throttle bodys question...

[Jon]

Ok, getting ready to do an intake mani swap on my F22A1 and am having some trouble finding an intake manifold with a throttle body, so I'm going to have to piece it all together.

My question is what is what throttle body will bolt up to a H23 plenum, besides an H23 tb?

[Granite CB7]

^for the plenum, any H22 or H23 will work, and same goes for the t/b's too. Both plenums are stamped "P13" (H22), and the F22a t/b will not swap over. If you end up w/ actual H22 parts, make sure they are OBD1.

[Jon]

So a H22 TB bolts up to the H23 plenum, just that I need to make sure that the H22 is OBD1, got it!
I had a few people telling me the H22 would not bolt up to the H23 plenum , guess I just need to stop talking to them...

Any others bolt up to the H23 plenum?

what about the s200 tb??

[Jon]

what about the s200 tb??

An S2Ks TB bolts up? What year? I know a guy who owns a 2001 and I know where he parks it at night

[bruno8747]

H22A OB1 or OBD2 fits the same

B-series fits

D series fits

S2000 fits

S2K fits, make sure its not the drive-by-wire TB (04 and up, I think).

The question was direct. It could also be helpfull in this thread. You suggested to a reader to look for free information on port and polishingS so since you do porting and polishing for a living, I asked you a question. Despite the head set-up (which BTW I am doubting you can even answer) please help us learn how CFM through porting and polishing translates to HP.

I know you aren't made of time, but a general writeup on some engine theory stuff sure would make a nice addition to our technical library, and you certainly know more to back it up than I do. I for one would appreciate that. Of course, if it doesn't get answered first.

No problem. Let's just see where this goes. I wish we could have gone into engine building theory sooner, but that never really came out of any of the threads. Now that I know what he does for a living and the fact that he is also a machinist, this should be fairly easy for him to discuss.

Thanks for the info guys. Maybe I will try to hunt down a 01 S2K TB to stick on my H23 plenum.

Now here is another question, how would one deal with a TB that is OBD2?

[IAmTheNight]

I don't know if OBD2 matters, but I have an S2k throttle body on my car. The only problems I had from installing it are not being able to adjust idle speed because the S2K TB doesn't have the adjustment screw at the top, there's a MAP sensor hole that you have to cover, and the coolant lines have to be rerouted because there's no fast idle thermo valve. It's a bit tricky, but it'll work.

What does your car idle at?

[IAmTheNight]

1100-1200

Has it effected gas mileage any (probably not, just thought I would ask)?

I might get a couple of different TBs and play with them.

my h23 tb provided me power to 6800rpms.
