T04E or something else?
 

Ok I'm looking to go to a bigger turbo now. The stock one just isn't cutting it. I have been looking at a T04E because i hear that they can put down around 400rwhp with minimal lag. I would like to have somewhere between 400 and 500rwhp, but also with not too much lag. I don't want the turbo to only make useable boost over 5Krpms. I would like it to come on around 3-4K or lower.

Here are my current mods:
Moderate Streetported 91 Rotor Housings, 87 everything else
3mm seals
Engine built by rx7 specialties in calgary
850cc secondaries
RP downpipe
Presilencer
HKS 65mm exhaust
HKS intake
Apexi S-AFC
HKS EVC III
Greddy TT
A/F and boost gauges
Bonez street/comp clutch and pressure plate
Volvo FMIC

The car will be mostly a street machine with occasional drags. It would be nice to not have to downshift to get some power. I'm going to put a haltech in with the turbo so engine management shouldn't be a problem. Also an inline fuel pump and a rising rate fpr. I originally was thinking of 1600cc secondaries and the stock 550cc primaries, but i was convinced to use 4x850cc. That should take care of the fuel side of the equation. I will be installing an aquamist system for h20 injection, so I should be able to run fairly high boost levels with the water injection running. SO basically I have a few questions:

-Which turbo should I go with? (T04E, another T04, T-66, T-78, etc.)
-Which a/r ratio should i use?
-Which trim?
-What would be the cost on the entire setup?

-2 850cc injectors
-Inline fuel pump or an in-tank unit
-Rising Rate fpr
-Haltech with all needed options to make this work
-Turbo
-Piping
-All needed fittings, o-rings, etc.
-Downpipe
-H20 Injection kit
-Tuning Time

-Also anyone running a bigger turbo on an FC please post your rwhp, track times, turbo setup, and any info you think would be pertinent.

Thanks,
