4.15L NA VQ Engine Build with Rebello and Zcargarge
BTW, do you have any dyno graphs of your car with the ITB comparing it to the original setup?
300+ LB/FT ................................ wow, just wow
. It seems that the MD spacer is the way to go with NA VQ35DE setups. You also picked up some decent power with the long tubes as well.
Congrats man. That must be very fun to drive
. Thanks for the comparo charts as well as sharing your build with the community

#'s look good Gabe, enjoy!
I'll try and make the graph again, I don't have 2 printouts side by side though. Only copy of the run files is pausing my dyno video where I zoom in on the graph.

Alright if you see this graph you'll see how it works with me explaining the Xs.
@5000 +20-25WHP (1st X)
@5500 +20-25WHP (2nd X)
@6000 +25WHP (3rd X, one near the big 300)
@6500 +20WHP (4th X)
@7000 +10WHP (5th X)
@7250 +35-40WHP (6th X)
@7500 +20-25WHP (7th X)
@7700 + 25-30WHP (8th X)
If you follow the Xs from left to right you'll see the gains.
The big 300HP mark is just showing where 300WHP starts from 6000-7700RPM is all about 300whp peaking at 315.
Keep in mind the tune isn't really complete because this was before any midrange tuning and the top end was just quickly made because the 9PM curfew for noise had to put a stop to the tuning that night and I took it home. I predict its got some more on the top end and you'll see even more under the curve later on too once they have time to tune it fully.
Let me know what ya think, I'll relay this to my thread and if you can figure out a better way of explaining it let me know haha.
not to mention you cannot compare cams on a stroked motor to cams on a non stroked. Completely different animals. The striker inherently let's a "big" cam behave more like a "smaller" one

Thanks for the kind words everyone.
Kevin - thanks for the graph. I'll respond to you on your thread.
I'll try to take some vids this week and post them up, but here is one from the other day. Not very fun and exciting but might as well show you guys since I have it.
5th gear pull from 60-100.

Zcar also modified the popcharger stuff so that I can have the heatshield and duct back on since my radiator and shroud was in the way. Also had to use a Ztube for now as oppose to the Samco one since there was a gaping hole in it.


They also found a great location for installing the oil catch can.

Congrats Gabe, really happy for you! There's another 20-30whp in a proper intake now for sure, considering we found 20 with a stock displacement, stock compression engine.
Couldn't be happier with the results our headers netted and with how the overall build is working out for you. Rebello sure did a fantastic job on the engine build!

Sasha - Congrats on becoming a Sponsor and thanks again for the headers. Yeah, I'm happy the way it turned out and so far it's running great without any mechanical issues.
I may very well fulfill your dreams of the 1/4mi pulls this 4/7 
Yeah, still working on the intake. We'll try out the 3" MAF first and then try some new intake parts in the near future.
