Searched:...nada on this/my set-up.

I have a stock block, JDM B16a, and stock JDM B16a head. My Mods in bio ...teh basics

I want to purchase a new intake mani. and I found a good deal on a typhoon im by AEBS w/ 65mm inlet.

What size tb should I go with for this? I was thinking 64mm or should I have it matched to 65mm???

I am also going to p/p the head, dual valve springs /titanium retainers/ 3 angle valve job/ stage 2 cams....in teh future

Or can I just have my stock B16a tb bored to 65mm for this typhoon im?

 

Come on...I see you lookin', but I don't see you replyin'!?!?

lol, that's what my stock B16a tb is right now right? "What you talkin bout willis?"

Wouldn't that run like **** if the inlet on the new intake mani is 65mm?

*confused*

 

Stock B16 is 58mm, GSR is 60mm, ITR is 62mm. The fact that the inlet is bigger than the bore of the TB is not a big deal.

 

Edlebrock makes a 65mm TB I just picked one up from Jegs ---&gt;http://www.jegs.com/cgi-bin/nc...r=361 for $319 it comes with a TPS and a Gasket, but not MAP.... I bolted it on wednesday night and it works like a champ... I can't wait to see what the actual differance it made on a real dyno, the butt dyno can feel a big differance

 

I would use a 62mm TB also and tune for the most average hp between 6k and 9k. A 65mm throttle body will benefit you the more on your b16 to fill the cylinder above 9000 rpms, IMO. But it varies with each b16 engine combo.

So why not go with a 64/65mm over the ITR?

So I should only go bigger than 62mm if I'm revvin past 9k?

I hear ya. I tried a stock 60mm TB, a 62mm TB/ITR manifold combo, and a bored ITR 70-65mm TB with aebs manifold on a cammed b16. I just compared how big you need to go in relation to engine speeds. I peaked over 800 rpms higher, with a 70-65mm ITR tb/aebs mani compared to a stock ITR TB/mani combo, but didn't make any more tq or even peak power with the bigger inlet. Your cam profile, header, and tuning affects where the motor will breathe the best.

Personally, i would rev a b16 with a combo where it breathes better...at higher engine speeds.

 

Thanks for info bro

I think I'll be going with the 62mm tb. That gives me +4mm over my stock B16 tb, so with some good tuning and the new im, I should see some decent gains...and when I get my head work done all the better

More info still welcome, would still like to know of all ya set-ups on the im/tb combos and what gains at what rpms you guys are gettin'. Pros and cons

 

no problem. my stock B16 throttle body off my 2000 Si was 60mm on the throttle plate side. the first gen b16's have a 58mm.

Start off with the 62mm TB and work your way up as trial and error.

Yeah I can always bore it if I need some more uummph later on after cams and head work

 

I have a Spoon 70mm TB for sale, IM me if you're interested.

 

yea, the first gen (cable trans.) B16's have the 58mm, the other B16's have 60mm. just send your TB to maxbore for $100 and he will do what you want. usually cheaper than an ITR TB.

 

Theres a guy on here in the classifieds that can bore ur stock b16 tb to 64 all the way thru and make a new throttle plate all for like 100 bucks.I'll probably be doin that

 

yea, maxbore.com, same guy i was referring to
