Ok guys I'm expecting to hit upwards of about 205-210whp on my type R next month and I have a Skunk2 IM and I was wondering if I should bore out my throttle body to 70mm or keep 64...or something in between??

 

its 62 if its stock

you can take it to 64, otherwise stock works fine

 

know anyplace that sells a 64mm TB or that bores them out??

 

Spoon makes a tapered 70mm to 64mm (iirc). Kenji knows a guy in CA who does good work though.

 

I hear RC does good work?? not sure though...what's the price on the spoon TB?

 

70 to 62 on the spoon.

Dude, spend your money elsewhere

 

K, I stand corrected. Kenji does know some guy who did his though that's good, if you really want a bored out TB.

 

well I thought the skunk2 intake manifold had a 64mm opening????

 

ericks racing is 70 to 68

ITR opening is 64 as well, but since the itr tb is good enough to make well
over 200whp why bother doing that first??

 

well I am already in the process of ordering my other parts...
cams, pistons, valvetrain, etc.........
so I was wondering if I would see any huge difference in power for the 175 or so to bore out the TB???

 

hey, if you got money to burn, send some my way

 

http://www.ericksracing.com has some that are 70-68mm taper bore..... if you insist on getting one.

I dunno how much good they'll do though, without port matching the IM and boring the interior of it too.....

 

yea a friend at honda is rebuilding my motor.....taking it out and getting the head ported and the header ported etc.......honing the block and putting in pistons etc......

 

you should get overbore pistons.

 

You got a gsr head?

 

what's the point???? I mean I know the labor isn't too much more but is there much of a difference...
no I have a type R head.....

yes there is a difference.
overbore is better.

and why did you get the skunk manifold?????

 

only got the skunk2 because my ITR was sold with my direct port kit etc...and I got a descent deal on the skunk2 and they had it in stock and everything 275

 

stock manifold is under 220 new
and imo its better than the skunk

 

well they had it in stock and he replaced it as they uninstalled on the nos crap that was sold...so oh well..it's a done deal..I know there is barely any difference in the 2 manifolds...but the question remaind...stock TB is fine? and go for the overbore CTR pistons? 81.25

 

yes on the 81.25
