NWP Big Bore 75mm Throttle Body Kit Review
As soon as I heard about the release of this kit I was stoked. I have been looking for new ways to improve performance out of my NA G Coupe without boosting and I have basically every bolt on already. The day it was available for sale I purchased it!
I installed the thing as soon as it was delivered to my house. Initial reaction was that everything felt and looked solid. no flimsy materials and everything provided for a direct bolt on.
Only thing you will need is a 3.5" to 3" reducer coupler if you're using a stock intake or sometime you can stretch the 3" coupler over the throttle body. whatever works.... It is a perfect fit with stock plenum or the kinetix velocity manifold. it does not touch the hood.
Once the throttle body was installed, I started the car up and initially it threw the check engine light. I performed the ecu reset, idle relearn and the codes were gone and have not come back. You can immediately feel a power gain even with the stock intake. I could feel the car rev much more responsively, but I felt that I could get even more power out of this thing. I had a custom 3.5" furookie type intake fabbed up and paired it up with a JWT pop charger and wow this thing really woke up! The car definitely needs a good tune at this point but even without it the good ol' butt dyno says this thing is well worth the money.
I cut the throttle body warming hoses off also because i didn't want random empty hoses showing.

I don't have a dyno, but my butt dyno says there is some gain up top. I've come to know my top end really well from the hundreds of passes at the strip. Above 6000rpm, it has more pull. Nothing mind blowing, but I know it's there.
When I installed it, I also had a CEL with a high idle. Did all of the reset procedures and worked well.
Not sure what happened the other day. I did a total of 8 laps around the Nurburgring. 4 "slow" and 4 fast laps. After I was completing all of my laps, the high idle came back for some reason. No biggie. I just did the TB reset procedure and it was back to normal. Also, the black plastic part of the TB rubs against my hood.

i am interested in where you had your intake Fabricated and if maybe another could be made and sent my way

Whats the bore of our stock throttle body? Also anyone know if a throttle body spacer is any good on our platform? I got a pretty hefty set of bolt ons on my 06 6mt g35. K&N drop in, Z tube, Kinetix upper plenum, Motordyne MREV2 lower plenum Motordyne ART test pipes, and Borla Cat back exhaust. I feel like im bottle necking at the throttle body and don't know if a spacer will do the trick to increase velocity after the throttle body or what? any suggestions. Oh Im also buying Osires UpRev standard tune soon once I decide on the final intake mod.
