What im adding:
CBRD BBK FULL PORTED TUBRO
8 to 9 conversion kit
walbro 400 fuel pump ????(DO I NEED THIS????)
Competition twin disc clutch?????? (What clutch is best)

I am hoping to make around 450 hp 430 tq on E85 Dynapack dyno

I would pull out your current Walbro & punch in the pressure relief. That & your RC 1200s should give you enough room for the BBK Full on e85.

street2dirt

is that what it means when people say they have a modded walbro 255?... if this could give me enough fuel that would save me money.

I need a good clutch to hold the hp and tq any suggestions?

I run a comp stage 2 and make a little over 400 on 93. I also used to run an exedy twin hd.

You should be good with a stage 2, but a stage 3 or 4 might be a better idea.

street2dirt

how did you like the twin disc? Ive heard mixed reviews, a lot of people don't like the amount of chatter

The chatter for the first thousand miles was annoying, but it died down. However, I always had the 'moaning seal' noise which occurs when the discs wear unevenely. I got about 36k miles out of it, which seems to be on the higher end. I'm happy with the comp stg 2 now. Especially being about 1/3 the price.

good info!

on a side note, how the bbk full?

Perfect. I don't see myself running any other turbo except a larger CBRD series turbo.

Throw in an Exedy HD Twin Disc, you won't regret it. Don't worry about the chatter its not bad at all, after all you're car is modded anyways.

I run a comp stage 2 and it's held up to abuse pretty well. When it goes I'll be running the same one, maybe a stage 3 if I build for it.

I'm running the BBK Full ported on my IX with 1000cc injectors, HKS 272's and full bolt ons. Tuned at 28 PSI to 452/424 at 6000 feet above sea level. I'm running a unmodified walbro 255 with stock fuel lines and stock fuel rail with absolutely no issues.
I'm also running the Exedy single disk stage 1 with no issues. What I'm getting at is you may not need to upgrade as many parts as you think if your tune is good. Oh, and with our setups being as close as they are, I wanted to say how fun this setup is on the street!!
