Just wondering if a skunk2 70mm throttle body with a s2 intake manifold would be too much air for my ctr motor or should i step it down to 68mm?

 

Any other mods done to the motor?

 

just a intake dc header and exhaust

 

2.5" exhaust if that matters

i plan to tun a 190lph fuel pump and the new s2 composite fuel rail too

 

i would also like to know im running a ITR motor though thanks! (motor has memfab whale ***** intake and toda tbelt thats it)

 

Seeing as your a CTR and you have a high compression already and some pretty decent cams id say bolt it up and get a street tune and you should see some good results. On my B16 I had I/H/E/TB/IM/S2S2 Cams and after I got my tune I was very impressed.

 

did you use the 70mm TB what intake tube did you use?

 

I would not use a 70mm on a mild NA setup. 68mm is a great NA TB. I would stay away from the skunk2 unless they fixed there sticking problem. I hated that.

 

i sell brand new blox 68mm or 70mm throttle bodies, essentially the same as skunk2 except it doesn't get recalled every year because of problems, $230 shipped to anywhere in the 48 states

Sticking problem?

 

When i had mine, if i was to completely close the throttle (example WOT then take your foot off), you would have to give it good force to get it to open again. It was fine at first but then just got annoying, if you adjusted the bump stop it wouldnt be fully closed. The problem was that the plate was to big for the TB area. Weither or not they fixed that problem i dont know, i just stay away from them now.

 

ive also heard some bad things about the skunk2's but my good friend has a 70mm on his h22 and no probs at all. if that helps or hurts the thread any

 

haha thanks guys but now i still don't know i'll probably end up going with a 70mm i'll talk to the guys at skunk2 and see what they have to say

 

Is a 70mm TB to big for a ITR motor? (NA)

 

i wouldnt get it i like the 69mm taper bore..The 75-69mm taper which is force fed as you accelerate eliminates any bog that you experience from a big straight bore throttle body, and ive seen dyno charts, its does make a difference.

Yeah, I hear ya on that. My friend bought a skunk2 intake manifold for his B16 one time and it was choking the **** outta the motor. Even after we brought it to a dyno (a well known dyno, too) they couldn't even get the numbers it was pulling with the stock manifold on it.

Put the stock mani back on it and it they got the same numbers again.

After that, I said skunk2 for shifters 'n such, not for air flow parts . I'm gettin my shifter skunk2.

 

sorry whats that and who offers one BDL?

 

BDL only has a tapered 74-72 TB. There 68 and 70 are straight through. I dont think any company maxs them off the shelf like that unless it was a bored out stock TB (like Maxbore. RPM might have them but even then i dont know for sure.

 

skunk2....70mm and port matching IM
