cjm s1 fuel return system. no need for the s1-s (fuel rails are the difference). the other is the Fast Intentions fuel return system. same style as CJM but costs a bit more.

BP turbo build/advice
 

For reasonable stock block power levels, the return is overkill. The fuel system as provided by Sasha is enough to get you safely into the 500 range on 93.

In my old Honda (yes Honda) without a return system, the last two cylinder's on the engine would get less fuel; that is why I was considering this. Is this true for the vq? Also I do want to bring the kit to 7200 rpm and I don't want be to lean up top or have a problem. So am I looking to much into this? I did want to shoot for 500-550. The shop I will be at has a mustang dyno and it reads kind of low. For reference I posted two dynos a few weeks back. Thanks man.
:tiphat:

Anyone know of any good tuners in tri state area. Michigan, Ohio, Indiana?

I'm running the stock returnless fuel system. Only changes I've made in fuel are the ones provided by Sasha (pump/injectors/relay). Going with a S1 isn't a bad idea and I'm leaning that way when I go E85. I'm currently running 510whp on 93oct and I monitor my fuel pressure all the time and it never dips even full load.

What's your gauge setup look like for fuel pressure. Trying to find a multigauge with oil and fuel pressure. Just ordered innovate ebc

Wasnt going to have one, but if i buy the fuel return it has it in the engine bay. I have the afr and oil temp/pressure from Innvoate and my boost read out will come from my Greddy Profec.

I swapped the local gauge on Phunk's fitting to a pressure sender. It was just another plug for the Greddy multi-gauge

Looks like i'm am going to go with the s1-s fuel upgrade. I emailed CJM to make sure it fits and for a little more input on what he thinks. For 900 bucks I can upgrade most of the fuel parts and not have to worry about it. You also have to work on the fuel system any way. After having a the lean condition on my last car I don't want to have to worry about that. Now only if I could get a Honda six speed in the G37!

VQ37VHR in a civic.... Game changer bro... Lol... I'm going with the s1 fuel return Just to be safe. If I upgrade and fuel expansion then I'll buy the rails.

I had a 03 accord coupe six speed. By far the best shiftier, only Porsche was better. Had carbon synchronous! smooth as butter!

Fuel pressure gauge questions have been answered. Now to oil pressure gauge. How important is that given in event of low oil pressure a light will be activated? I'm going with innovate boost control that will show a/f and boost psi and also had safety cut for low a/f. Just trying to figure out if I need two gauge or one gauge pod.

The innovate oil pressure/temp gauge has settings for when it gets too hot or pressure gets low.

Car already has oil temp gauge and has a light for low oil pressure. So I a gauge needed for oil psi?

I would actually disagree. Having the proper fuel system in these cars is probably the 2nd most important thing to have besides a proper tune. Will Sasha's supplied fuel system components work? Yes, but is the CJM system overkill? Not by anymeans. I would highly recommend running a fuel return for anyone running forced induction. Being very close with Tony@FI, I know first hand the amount of tuning they did and reasoning behind them coming out with their own fuel return. On the upper end, if and when the fuel leans out is when any forced induction application has had issues. The fuel return ultimately eliminates this all together and gives great piece of mind.

Yes, why would it not fit? Phunk's rails and full fuel return is also what I'll be going with, along with a few custom goodies to modify my current RRP for track use.
