Most of you know I've been wanting to build a good normally aspirated (NA) engine for quite some time. I have been talking to Jeremy at the Performance Factory for over a year, and finally things worked out... It was completed yesterday!

I was fortunate to find an '06 revup engine with the dreaded oil consumption disease that was for sale. I bought it and took it over to Jeremy's shop so he could work on the engine while I still drove my G35 Coupe. That worked out well and things got rolling. I took my car over a little later and Jeremy swapped the new engine in, along with a new flywheel and clutch, and got everything running.

I wanted to use good parts for my engine. Some of you might think that some of the fasteners and gaskets are overkill for an NA engine. You might be right, but I wanted to build it with these parts. There is also a possibility that I might throw a bottle of Nitrous in the trunk some day... and I wanted to know that everything would be safe if I did.

As far as I know, this is one of the first NA RevUp motors built to make power at high RPM. It presented a few extra problems along the way. Fortunately, I have been a beta tester for UpRev's Osiris Tuner package and it (along with Jared's help) solved a few extra problems.

Here's a list of the new parts that went into this build. I really have to thank Jeremy at the Performance Factory for his help with this project. In a lot of ways, this engine is an extension on his original NA motor, but with a few modernizations and updates. His advice was just as important as his building and tuning skills

I know everyone wants to see the dyno chart, so here it is. After the dyno break-in my G35 made 312 rwhp on the Performance Factory's DynoJet. Good numbers for a completely new NA engine. Jeremy also took the time to go for a ride with me and do a little street tuning to make sure everything was tuned to perfection. Next time Jeremy says hold it in gear to 8,000 I'll probably look up for cars first... That was a lot of fun!


Here's where I found my Engine... Under Joe's workbench... mine is the one on the left... a perfect 222222 waiting for someone to come along and pick him up... It's a 2006 RevUp with less than 5,000 miles on it... Very nice motor... Thanks, Joe!


Here's a shot of Joe and Christian helping me load in onto the back of a truck... Hey, I helped... I had to stop and take a picture, though...


Here you can see that my engine made it to the Performance factory... Jeremy, "The Captain" didn't think I was really going to take this picture...


Here's a shot of my parts as they are close to being assembled.


Couple of shots of my JE Pistons. They were custom made by JE to Jeremy's specs for the best combination of power and their ability to run on 93 octane gasoline.




Main Studs...


Short block assembled...


Cylinder head...


Heads assembled with cams...


Here's a shot of my engine bay after everything was done. All that work and new parts and it doesn't really show... it's good news, actually... You wouldn't ever know anything had been changed.


I've always wanted better gauges. Oil pressure and water temperature gauges are pure necessities to me... and I wanted an air/fuel gauge so I could easily tell if anything changed in the A/F area. I finally decided on an A-Pillar gauge set because there really isn't a better place to put gauges in a G35. I'm happy that I got it because the gauges are very easy to read and they line up with the A-Pillar perfectly so they don't restrict my vision.


To say that my car is fun to drive is the understatement of the century! The new engine revs freely to 8,000 and just loves the 4.08 rear gears. It pulls much, much, much harder than it ever did before. It is a blast to drive now. I realize NA engines are not for everyone, but it's exactly what I was looking for!

This is really just the start of this project... there are a few more things to try... hoping to get one or two of them done before Jeremy relocates, but I may have to make the trip up to NC some day. Thanks, Jeremy! I really, really appreciate all your time and hard work!

I see you left the stock air box on, any reason? I was thinking of going back to mine. Is all 3 gauges autometer, if so what kind. I think they would much with the factory dash

Awesome job!!!!! What was your final compression?
Your motor with out a doubt will be the strongest NA motor here once it is completely broke in. Once you get more mileage I'm sure you will pick up some more hp. Great work!!!!!

Thanks...

I remember Jeremy saying that that particular dyno chart started at about 3000 rpm and peak power was around 7500 rpm. He revved it to 8000 most of the time, but I'm not absolutely sure about that particular sheet.

When Jeremy built his NA motor he tested lots of intakes... None made more power than the stock air box... that was good enough for me... thinking about making one change in the intake system, though.

All three gauges are AutoMeter... water temp, oil pressure, and Air/Fuel...

It was designed to have 11.7. I don't know if it was ever actually calculated manually during the build.

I think these NA built motors are the biggest secret on the forums... I know you're loving yours, too... Thanks for posting your threads... lots of good information...

You're right, Adam... I am just loving driving it...

Thanks also for your big NA thread... I read through it more times that you can imagine...

jb, congrats on getting your car done and now its time to enjoy it. What do you think about the cams? PM me if you want

Hey where is more pic?! Congrat!!! damm hopefully economic gets better so i can start play with my engine.

jb, I just realized you went with 500cc injectors. Were you reaching 100% with the stock injectors? Also, comparing your power band to mine I have some dips between 1500 rpm and 3000 rpm then it smooths out and your power band seems to come on pretty smooth all the way to your peak. I remember Jeremy had similiar dips in his power band to mine as well. Do you think the haltech is the reason your power band comes on so smooth? As far as your VTC angles, did you have to advance the cams to their maximum between idle and 5500 rpm or does the stock advance work with these cams? Thanks for your input and sharing the details on your build!!!
