I am going to be upgrading to a larger HG and increasing the boost on my car to around 15psi I have a couple of questions. If you can help let me know. My goal is around 400hp.

What is the max injector size for the E manage Ult, and what would be the max HP on our cars that it could handle until you would want to switch to a stand alone.

Should I do a 2mm or 3mm hg not wanting much more than 400hp?

What injectors should I use 675 or larger and brand?

See mods below, I have a gt3076 .86ar turbo on the greddy kit curently around 330hp at 9.5 psi.

 

help?

 

You should be able to run 750 injectors..
I personally would go 2MM but I wonder if the inline 3MM is a better gasket?
I think you should be fine with the Ultimate also. I heard of people running 400 HP with the crappy Blue E manage.

 

My tuner and I am leaning toward the 2mm do to my power goals as well. I hope I can run the 750's cause I want to be around 65% with my injectors. Any specific type of injectors should I run? Do you think 15psi is good to shoot for?

 

I would go with 750 RC injectors.

15 or so psi sounds good to me and I am curious to see how things work out for you.

Do you have a clutch?

 

I would suggest Siemens deka injectors. They have a good spray pattern for fuel atomization. If you click on the vids in this link the RC injectors are very similar to the Genesis you can see the difference is pretty obvious. Good luck with your build.

Injector Spray Pattern

 

Yes, I have a stage 4 competion clutch and light weight flywheel. It's a bit touchy but seems to work OK. So far the bigger turbo on the car has worked pretty well. Seem to provide about the same results as any inline pro kit or any other kit with out a 3mm HG. Being able to run a 3" TP is a huge diffence, doing a upgraded down pipe should really help greddy owners cause the way they made it 90's into the side instead of coming together flush also it's too small. I took my TP off today and put on my berk HFC and wow the car feels so much slower, I can't wait go go through emmisions and put my TP back on. I will be moving forward over the winter to get the 2mm hg, injectors and retune completed. Once I hit close to 400hp I'll be done cause that's all i'm gonna need.

 

i've mentioned this before, but there are R34's in japan running 1000+ hp running the ultimate. So it should be adequate for your goals!

 

Is a 3" test pipe that much more free flowing than a Berk HFC? According to their website it flows 87% of a test pipe without the smell. I am willing to give up 10 hp to not have the tp smell.

 

that maybe true but their ecu's are already designed for compensating positive pressure. piggybacks generally work very well on factory turbo cars... at least a lot better than they do on honda on boost
