Not alot of people have dynoed those "new" efr borg turbos. Sounds like you are looking at the 7670? That looks like a very promising unit for sure i say go for it. I was going to get that same turbo, but the lack of real world testing and unknown general reputation of the efr series steered...

.68 t4 is a pretty sweet deal and i think probably a good bet for your requirements. But i still would bet u would need to run race gas / alcohol to get your goal. I will be surprised if i hit 450 with my set up on pump only @ 16 psi

I have a .91 twin scroll on my sw360. I am hoping to make around 450 @ 16 psi on sunoco 94. On my 1j with 272s my powerband starts at over 4000 rpm. Feels like i am around there right now but i wont dyno until early 2014. With the t3 .63 housing response would be much better but you would...

Still says these are unavailable in the link? Any idea when these will be available? Need my tems!

I am going to use fic when i go e85. My tuner likes them because they are the most dynamc, aka huge injectors still offer great idle control.

For the same price you an get a borg warner s360 60mm. Much better in my opinion.

Lookin great! Those wheels set the whole car off.

Thanks for the parts list and write up. I will probably pester you with questions when i tackle this.

Of you are looking for an upgraded clutch i really like my spec stage 3. Takes a while to get used to, but once you figure it out it is great.

That is exactly the unit i am considering. Any feedback on it?

Nice! What management?

Did you run out of fuel? I bet you could crack 600 rwhp at 30+ psi easily.

For real! What a tease. I would be curious to lnow what boost / fuel was used as well

I I live right by Sonoma raceway they have sunoco 94 through 110. But the rest of the pumps in the state (not at tracks) only have shitty 91 octane.

live and die by the wideband o2 gauge. http://www.summitracing.com/parts/avm-30-4900?seid=srese1&gclid=CNCmsa6_k7sCFeU5Qgodc3YAmg i try to get my closed loop cruising and idle as close to 14.7:1 as possible. When in boost i try to run at 11.2:1. a little rich, but we have shitty 91 octane...

i have been on the same apexi safc II for almost 10 years on both a 1jz on twins and two different singles, and a 7m with the lexus afm and 550s. for the price and ease of use I got no complaints. I have only had a slow pump gas car running less than 1 bar. the apexi safc II can be a bit...

i ran that exact set up for a few years on my 7m. it was great, and required no closed loop tuning with the AFC. i agree, unless you are pushing the injectors, no need for afc and walbro.

Would it be possible to get a summary of what parts you used, cost, and the "how to"?

Looks like a huge improvement over stock!

Damn it. I fail at SM, this should get moved.
