I live on the north side... but recently moved so I am between Milwaukee (by the stadium), Mequon (in-laws place), and Whitefish Bay.

Yup got an RB... Unfortunately I don't have an 25 (I assume you based your 30 on the 25) so I don't have all the parts to swap between the two. However some stuff will still work (for example coils), and I am actually a firmware engineer (mix of electrical and software), so I have a pretty good understanding of electrical and have easy access to scopes and stuff that may help diagnose it.

Yes. Owned (sold) a Zenki S14 with a 20, and now this Kouki. Had my SRT-4 in between the two S14s.

I'll post some exterior pics up on BCM once I get the new rims/tires in.

yeah i based my rb30 off the rb25. All electronics, harness, and sensors are the rb25 ones. So it should be easy to diagnose. Im shipping my harness out to Carl H tomorrow morning so hopefully he will get it done sometime next week and ill have it back the week after.

From my understanding, you had an agreement with Mark, S14-NEO. He went out and bought materials in preparation to give you a quick turnaround time to get your car back going quickly. Now he is out $40. I really suggest you pay mark for the inconvienence you have caused him, not to take anthing away from carl either as he is also a good freind of both mine and mark, but if you have an agreement, stick to it. Make things right will ya man.

on a side note i hope whatevers buggin out on your car, gets fixed however it does get fixed. Im just a little miffed at the news i just recieved.

i am so confused right now on who to send my harness to. Carl H emailed me yesterday with a MUCH lower price quote on doin my harness. and being a broke college kid that looks ALOT more tempting. If you did in fact buy all the supplies to do my harness already then i will ship it to you. Im not about to screw you out of money. So please respond to this thread or via email by tomorrow if you did in fact buy the supplies. The reason i have not contacted you is because i had not for sure made up my mind on where im shipping the harness...

look man i didnt come back in this thread to make you feel bad about your decision. you and i had worked out a deal and i felt it was pretty much a done deal so i went and took the necessary preparations that was needed on my part in order to expedite your harness quickly. you do whatever you "feel" is right..im sorry that money is tight for you , take a look around you and youll find that your not alone.

I raced my buddy in his 6.0 GTO and was dead even with him from 10mph to 80mph when we let off. and im only at 8psi right now and running pretty damn rich. I also Stomped all over a Big turbo eclipse GSX and a couple evos. So last night changed my mind on my car

Well, glad to hear your going to keep it. I reloaded base maps last week and have started retuning.

Great to hear its back up and running.

Can't wait to see it out on the streets. You should bring it to a local show!
