The small turbos we have spool and hit peak torque just before 3k rpm, so the power hits pretty hard and things will start breaking (like they did for me, ringland failure) if you’re trying to hit 350-400+whp (27-30+psi). I went down the route of building the engine and it’s been quite a process because there haven’t been many of these built. But it’ll be a pretty great track car once it’s finished.

Exactly. I got a bigger turbo for that reason and we'll tune her to smooth out the power band especially early on to minimize failure.

Can I just say HOLY SHIT on your setup? That's insane

Nice build, Im assuming you've been to the strip with all of that work invested?

I guess 12.83 stands as the World's Fastest N20 with apparently way less work/modification.

Hoping one day, someone with big mods will post a slip.

I'd heavily disagree on the less work aspect. Let us not forget that the JB4 was tuned by the driver and how dangerous it was for the engine. Just saying.

Very fair statement. I wonder if we can break into the 12's without going to such extremes.

I think it's possible with guys running upgraded rod bolts and turbo on an ethanol mixture.

Agreed. With a 13.4 coming so easily with good tires and Dinan sport, I wouldn't be surprised to see mid-high twelves from a solid FBO build.

I ran 13.2 on just Bolt ons stage 2 tune and e30. It was also 84 degrees with 70% humidity lol. I just dove head first and purchased my rod bolts. Planning on going 6758

Do you have an Ig to follow your build?
Im currently trying to do as much as possible to mine but I cant seem to find a shop that will work on my n20 plus at the moment I do not have momey like that I am still a college student 😂

D041987 · 02-19-2019, 05:02 PM

Unfortunately No. Not big into the social media. Car was just a fun project and I did not document or take many pics of the build :-( Maybe one day I will post but I am rarely on here. Might be selling car soon as well. Want to get a good jeep as a daily and buy an older E30 and swap in a M52 Turbo to get 400-500 whp for cheaper/ fun experience.

Before you do, can you get some videos and post 'em up in this thread? Would be cool to hear how a 430WHP N20 runs
