im in the middle of trading my del sol seats for an itr manifold and throttle body. i dont have a mic on me to measure the diameter. is there any other way i can tell if its a legit ITR TB?

 

on the back of the manifold on the driver side it will say P73

 

here are the pics that the other guy sent me...

 

yea, i know about the manifold saying p73 (i should have posted it sorry). but what about the TB? im pretty sure there is a diameter difference but i dont have a mic with me to check out the size. are there any other differences?

 

Its an itr but check the stamp in the back p73

 

looks like a itr mani too me but check for the p73. and ask him what happened to the throttle cable bracket...lol

 

ok, i get the stamping but is there any physical way to check n make sure its an itr throttle body?

 

Doesn't an ITR IM have smoother-looking runners than normal?

 

from what i read, it is straighter on the runners where the b16 was sort of at an angle.

i posted this same question on the itr forum and not a single response.

well, looks like ill take a gamble and trade. either way the manifold itself should be a nice upgrade.

 

yea it does have smoother runners and plenum.
this is a usdm b16a2 im

 

well, i picked up the manifold but there is a difference. i didnt see any p73 stamping on the back. i got it home and it lined up with my obd0 pr3 manifold. i will take it to work tomorrow and match it up with a b16 intake manifold gasket.

 

Looks like a OG Skunk2 manifold to me.

 

would there be a downside if it were a skunk2 manifold? from what i remember the skunk2 manifold was similar to the itr, right?

 

might be a blox

 

i have heard of blox and skunk2 being copies of the itr manifold. well here are some pics i just took with my iphone.

obd0 PR3 intake manifold


New manifold...

 

looks good...still better then a b16 mani

 

well i don't think its necessarily an itr, but it's still an equivalent upgrade i would think. i agree that it very likely might be an older style sk2 manifold. it looks extremely similar to a skunk 2 replica i bought sometime ago anyway.

 

Did you buy this manifold for your B16A? If so, there is a pretty good chance you will lose power with it.

 

i didnt buy it, i traded my set of del sol seats for it. it will either go with my LSV or my JDM ITR motor for later on after its rebuilt.

no b16 motor for me, just a b16 head. so will i still loose power even though its not a B16 and im running an obd1 LSV?

 

This. Stick to a P30 manifold for the b16.

The manifold you have is most certainly not an OEM ITR manifold but it is a copy. Older Skunk2 or blox

 

how would i loose power running this on my LSV? i thought i would gain at least some high end power?

 

oh lol, didn't see your post. Try both to be honest. What does your lsv build consist of? Check out the all motor forum, I've seen more than a few threads where the P30 manifold does better than the ITR.

 

It's for the most part a stock lsv. No actual performance parts. I'm saving up for a complete build up of my jdm b18c. Just gathering parts here and there, the main purpose of my lsv was to get the car set up and be ready for the new motor after it's ready to go in.

 

well my buddy put an old school skunk2 mani on his lsv and it seemed to gain more high end power

 

That's what I got from some postings online, but u haven't ran one of these before.
