I have a 98 Gsr block (stock Internals) with a 98 ITR head (stock internals).
I have no problem with that part of my engine, the part thats killing power is the intake system. Its off a 1st gen B16. So i have a undersized TB and the Intake manifold isnt as good.

I was originally going to go with a JG edelbrock Intake manifold, i was told it was too big and better for turbo's. I have been told to get a stock ITR intake mani, or a Skunk 2. Is there anything else out there thats maybe a bit better?

Now for the throttle body, I was thinking about the 65mm edelbrock one, or the 68mm Holley one. Is there that much of a increase over the extra 3mm? Its going to cost me a extra few dollars but i dont really want to spend it if its not all worth it.

Any thoughts on what Intake Mani, and Thorttle Body would be best for my setup?
I dont have any plans for boost in my future, maybe some internal work down the road later.

Thanks,

-Eric

 

from what ive heard the aebs gsr manifold is coming out soon mid or late january.

 

ITR intake manifold with ITR TB and a 3" shortram CAI..

 

I think you're only going to need an ITR TB for your application right now. ITR/Skunk2 IM are proven. Then just get a short ram or CAI, then you're good.

 

the cheap way is a aebs intake manifold and a gsr or itr t-body

the nicer option is a ported itr intake manifold with a bored out itr throttle body

you will need to make sure that you have a way to tune your air fuel ratio because both of those parts will make the car run leaner

 

Get an AEBS, and stock ITR TB, or bored out GS-R TB. (as has been said)

However I would recomend a J's Racing intake, or a Comptech Icebox.

 

what's the bore on an ITR and GSR throttle body?

60mm for GSR, 62mm for ITR

 

the actual intake wouldnt make that big of a difference

i would just get a short 3" intake arm with a K&N filter

 

So it seems like the majority is sugesting i go with the ITR TB and Intake Mani.

Thanks, ill look in the classifieds and on ebay for the TB, Intake mani i already have a hookup.

So which is it...? Shortram, or CAI...?

Actually, I have experience w/ both and short ram does give better throttle response but tends to get sluggish up top... With CAI, low-end seems to be a little diminished, but top end pulls hard... Especially when the runners open up...

Think about what you are saying. A short ram is SHORTER, and has less bends than, say, a AEM CAI style intake. Top end is actually much better with a short ram intake....dynos don't lie.

I was just explaining how it "feels"... Maybe I shoulda been more clear... I haven't dyno tested either one, however my cars "feels" stronger with the CAI...

 

ah yes, yee ole bum dyno. it's all good man.

Yeah gotta love that butt dyno... May not be accurate, but sure makes feel a whole lot better about some purchases...

what is your redline?..

the advantage of the shortram is above 8000 RPM, so if you are staying under that or barely going past that to 8400 RPM then a CAI is for you...

 

Well, I'm running a stock P-72 ecu so the redline is 8100-8200rpm... But I usually shift around 7800... Stock rod bolts don't like 8000 grand and above revs...

 

Sweet ive got a couple 2.75" Short Rams, everyone said they were Junk, I almost bought a AEM CAI.

Ill guess ill stick with the Short Ram!

Thanks for all the Info guys

ok, guys your saying that the short ram make more H.P...? above 8k..?

 

what's killing you too is your stock internals on your GSR block with ITR head.

gsr pistons in an itr head will yield a low *** compression. get jdm itr pistons. cheap, seal well, and will make alot more power than your gsr's.

 

you people are so funnie, the best intake is no intake. haha.... n/a... doesn't matter your engine can only suck in so much. 1.8L. your stock one is fine. unless your running turbo. you don't need it. and even if you did when out and buy one. it might even make your car even slower. you want the more free flow with the most velocity.
