Damn... That engine looks fiiiiiine!! Nice work mate, what do you do for a job? Lol
But seriously, what is your power goal this time?

I'm a mechatronics engineer, working as a software engineer.

I'm expecting just under 300rwkw on normal 98 fuel after all this, and easily 300+ rwkw on E85 :-D

Nice move going to COP.
 
Strange the RacerX cam sensor is done so poorly. He normally does things quite nice but that just looks odd. Will you be making a cover or just leave it like that? Crank trigger being adjustable too?
 
Certainly looks alot more serious now thats for sure!

RacerX has had at least 2 revisions of the cam sensor. Their latest design uses the right engine mount for the sensor, and a trigger on the exhaust cam gear, instead of using the distributor location.

You engine looks mean even out of the car!  Congrats on your latest incarnation :)  I'm looking forward to seeing the dyno figures

Dumb question. But what is the slotting on the trigger wheel for? Setting the base timing or something?
 
Looks like you'll be in the 300KW club with this one.

I assume you're talking about the 6 elongated mounting holes.
Different aftermarket ECU brands have different requirements for the location of the missing teeth relative to TDC, so I guess the elongated holes are there for that reason. Anyone who changes to a completely different crank trigger is obviously running an aftermarket ECU or at least a non-standard 'triggering' setup, so the mounting holes "may as well" be elongated for adjustability.

Maybe slightly under 300rwkw on 98 fuel, but with E85 it should easily exceed 300rwkw.

Needs a cover like this

This is starting to remind me of my build now with what you have done.
I was looking at the cam sensors that people have tried and couldn't find any I liked the look of so have just stayed with the std dissy with a alloy cap on it.
 
I also have the same clutch

I found out something surprising when I talked to MRC recently...apparently my turbo is actually a GT3082R, but all this time we thought it was a GT3076R! For those who don't know, a GT3082R has the turbine from a GT3076R and the compressor from a GT3582R.
The reason this situation came about is because my turbo was very briefly used by a different workshop on a different engine before ending up on MRC's shelf for a while, then MRC sold it to me for a good price because it had been used (for a very very short time). MRC was told that it was a GT3076R, so the workshop which originally used the turbo is at fault for misinforming MRC.

This discovery might explain why the turbo has slightly more lag than I initially expected it to have, but still a bit less lag than a GT3582R.
The GT3086R may have a reputation for having a 'mismatched' turbine and compressor, but I've been happy with it (and of course I've been oblivious to the mismatch all along)! I've never experienced compressor surge or anything like that.

The only reason I'm even mentioning this is to avoid misinformation on the forums.
