Anybody know what the market is like with N18 (2011-2013) internal upgrades? I am currently on Manic Stage 3 and dyno'd 261whp 271wtq.
I'm at about 22 psi on a K04 and would like to do some upgrades soon to the Rods and Pistons. Eventually want to run 25psi or so. Only choice with some research I see is JMTC R-Forged Pistons N18.

Didn't really see anything with Rods.
Also, any options for a clutch? OS Giken is nice but way too expensive.
Anyone have some input in these areas?

Thanks a lot

 

There is a very thorough thread HERE that might help answer some of your questions.

 

Thanks! Great thread.
Anyone have information on Clutches?

 

I chose Giken --- good reputation to match the high price! No issues so far ---

You might want to check the various rod / piston mfg's web sites, then find a distributor. I ended up with a CP / Carrillo set for my N14. Altho, my OEM set handled a dyno'd 280WHP for 3+ years. Maybe I was just lucky?

 

That impressive on the stock internals, did you use meth and what was your AFR? Did you change you stocks before they blew?

Using HFS4 50 - 50 WMI. Original dyno --- http://www.accessecu.com/dyno/ Only Mini at the Surgeline facility. Note that AFR is just under 12 and boost is 14 - 17. Another chart from 17 - 20 wasn't put on line. That one was 282WHP, similar linear curve. Most recent dyno not on vendors website, but can be seen at --- https://www.northamericanmotoring.co...a-stuff-2.html post # 28, Best run not available, but close enough to these. Yes, internals were changed to prevent a disaster, knowing another tune was coming with 28PSI. Since then, turbo was replaced. Next dyno should be a bit over 300 with 30PSI.

I'll be at ThunderHill Raceway for the Mini event on Valentine's Day. Expect to dyno there. Are you planning on attending, or sending a co. rep? Usually a big crowd. Long drive from Ventura, but worth it, if you have the time.

 

Is it safe to assume that wasn't with the stock turbo though, correct?

 

Correct! Turbo was the first thing I changed. Hybrids and other replacements weren't available in early 2011, when I started upgrading.

 

I'm thinking about it, and it's pretty far to drive on a slammed Coilover GP. Will you be going?

My fees are paid for the Hooked On Driving session Saturday, and I'll be watching friends run on Sunday, leaving Sun afternoon. Possibly a dyno run on Sunday. Also want to talk with Jan about one of his tunes, altho he's already expressed concerns about my FCD's --- bad practice to cheat the ECU.
