well im on a built block too and i was leaning out over 15psi so i had to scale it down to 14.5psi I was started running out of fuel so had to upgrade from a single pump to a dual pump. You might also need bigger injectors to hit ur goals. Just letting you know the stuff that i came across. But my fuel pumps are in now and im getting my new tune this weekend. so i'll let u know how that goes. good luck with your build man

I don't think anyone has done a 370z with a new single precision ball bearing 6466 that I know of so it should be interesting..

keep us posted ! =)

Currently I'm running a single aeromotive 340 with a fuel return system from cjm and a fuel lab fuel pressure regulator based on vacuum.. Also I figure the 80% rule with the fuel injector duty cycle should be fine with my 1000cc injectors...

Passenger side is all finished, driver side is still probably 6-8 weeks from being finished. But for now we are just building manifold/turbo/downpipe kit. Probably not a whole turbo kit.

Will you be using v-bands or what?

Yes the manifolds have Tial V-Bands on them.

I have decided to go upgrade my aeromotive 340 to a 400 aeromotive. After doing a lot of research between twin scroll or T4 it seems the twin scroll will spool faster but a regular T4 will make more hp and tq.. So many things to consider with pulse rate of our cars since it is a V motor and equal length runners in such.. I also may bump up to a 1.15 AR but again I still have a lot of things to work out..

Sasha already figured all that out^ and I'm pretty sure his kit comes standard with a 1.15 ar could be wrong tho. Just buy his kit, install it in an afternoon, make power.

:drama:

Bringing this thread from the DEAD!!!!

For those who care and those who don't here don't care here goes......
Built motor from Bobby=Vortex, VSR, PRS,RJM, etc etc etc blown at around 2k miles. The cylinder didn't crack but a chunk was taken out.. lol
Yes I put my faith and lots of money in this guy to find out he can't leave the state of FL due to fraud over 50k, paying on several judgments to others to whom he has blown their motors as well, etc etc. Needless to say after speaking with his probation officer I no longer have any dealings with bobby Ralston.
Goods news I'm having bryan brooks build my new closed deck block with the only precision gen2 twin scroll 6466 switching from uprev to ecutek (no more maf issues with high boost). Before my motor blew it dynod at 748whp and 705tq at 25lbs. I've decided to continue this thread in hopes of saving any other unsuspectful people from his full line of bs but not to to be bashed ( in which I'm sure that will happen anyway on this forum).. Stay tuned and I will post up the motor pics.
Peace...

Yeah baby!!!!!
Turns out my internals are good but will replace the bearings and maybe pistons rings. Had my lower intake ported and polished and few other flow issues addressed. New block is at the machine shop soon to be bored and everything balanced.

New closed deck block and new front bumper.. Having the motor acid dipped before boring process..

Coming back from the dead is right. LOL Well, Cosmo good luck to you on this build. Hopefully everything goes better. :tup:

Thank you, like I said it's been a learning experience and a long journey but I'm not giving up.. :tup:
