I found my percentages for corrections had to dramatically decrease.
For example, my cold start enrichment I reduced by aroudn 75% over what it was originally.
I believe cable ties are mandatory...
My last track day I got knocked back as my ecu wasn't stuck down... I was told it required cable ties and then it'd be fine...
The main thing will be as mark said, no oil leaking every where, nothing loose in the cabin to act as a projectile, and seatbelts/seat are good.
That sounds EXACTLY like my car does when the fuel and ignition were not tuned right, and the acceleration enrichment was not setup right.
The accel enrichment is an absolute bitch to get nice and sweet on most cars with big injectors, do able, but takes time for those who haven't done it before.
My biggest issue was clearance when bringing the seat forward...
I'm bolted dead to the floor... The stupid factory hump gets in the way... But it seems nearly perfect for me...
When the cage gets done, I'll move it closer, and lower, and cut the hump out...
The other issue I had was with the shoulder wings smashing the door...
Did you REALLY search?
Basically ALL of those questions are answered in the RB25/30 guide, which is in the RB30DET section...
Go have a look, really...
Duncan... May I be the first to say... I HATE YOU!
You're not allowed more fast cars, yet alone an awesomely built RB25/30 with AWD!!!
I want AWD...
Looks schweet... Is it auto or manual?
LOL @ the people saying it'll crush up/burn...
1: It's the end of a spark plug. It won't burn
2: While it's being "crushed up" it's being slammed into your bore and gouging the f**k out of it...
3: When it reaches the head side of things and gets to the valves... Even more trouble...
I have a piece of piston come loose and "crush up" in my motor... It took everything out, lost compression through the bottom end, and also smashed valves... And the only sign? Masses of blue smoke on throttle, and a lumpy idle.
As nismoid said, 1000RPM for 30 seconds... It's gone around and been ground to pieces 500 times... PLUS you heard all that nice clunking...
You've 99% likely farked your motor. Start stripping it out.
If you put the new plug in, and started it, don't worry about pulling shit apart, you've already f**ked the motor.
Just go and drift it, when you get home, strip it, and rebuild it.
