What is necessary to run T04S?
So if I wanted to install and run an XS T04S, what would I need to safely support up to 15psi?
FMIC
550cc/1300cc
Catback
Downpipe
Intake
ECU
Fuel pump(s)
Shooting for 400rwhp on pump gas @ 15psi.
I'm not looking to port anything so if I'm missing anything else besides the above please let me know. Also a lighter flywheel to help with the revs and bring down the lag a bit........

you need to get a midpipe too with that XS kit and also dyno tuning as well to get the most power out of your car. You'll also want to get ignition upgrades: a b and m ingnition amp, hks iridium plugs, and magnecore wires. If you don't upgrade your ignition, the car will misfire at higher boost levels (general above 10-11psi)
The T04E is smaller than the T04s, the S is capable of making bigger numbers but you sacrifice a little low end power.

Damn that's a big power difference. Would the T04E be a lot cheaper as well?
I'm hesitant on getting a midpipe due to the fact that I don't want my car to sound like total **** or smell like ****, perhaps a high flow cat might be possible?
Victor - when you say sacrifice a little low end power, will that effect much as a daily driver?
Thanks.

Look at their dyno charts of both of these at 15psi.
Can you back up your claims of 150 more rwhp?

You may not be able to achieve both 400 rwhp and only 15 PSI with a high flow cat... it might be possible, but just don't have your heart broken if you only hit 375 or something or if you need to up the boost to 17.
Also, I think to be safe you should go for 550/1600. 550/1600 is what I run on my T04S and I hit over 90% duty cycles now. It is true that I am running too rich right now, so maybe you could get away with only 1300 if you tuned it "just right" but you wouldn't have much room for error.
I agree with the other poster that recommends an ignition amplifier... I use the HKS Twinpower with no problems.

God damn, 1600cc? How much gas do you consume with that size injectors?!
What about 850cc/1300cc combo?
My ideal objective is to use a T04S with street boosting at 12psi or so, 15psi-17psi during runs/races/track/dynos..... Would like to see at least 400rwhp on 91octane.... Supported by all the necessary complementing upgrades, but not too interested in any ports as of now..... But would it be better to get the motor even mildly ported?
Thanks guys.

Go get some 1680cc/min injectors (165#/hr). They're cheaper than the 1300's and (I believe) than the 1600's, and can inject more fuel. I got my pair for like 185 shipped (I think you can get 'em for a bit less however). Running a TO4B 60-1 at ~15-16psi I'm seeing duty cycles as high as 80% or so. If you ran 550/1300's then you'd be at 96% duty cycle, and i'm on a STOCK PORT 13BT (ports are even smaller than 13B REW ports). Basically if you want 400 HP on the ground, you're gonna need more than 550's and 1300's .

This is supposed to be a technical forum, not the lounge.
If you are going to post comments on power and performance claims it would be nice if you could back it up with some proof. Dyno charts would be nice. Time slips would be nice. Opions are next to worthless to me without proof.

For fuel, consensus seems to be on a set or 1600's, but what about the pump? Fuel rail? FPR? or will the 1600's tuned with an ecu be enough to run 15 psi?
I know there are all kinds of extra variables, but lets say for a small street port or stock port REW motor with all the normal air flow things also.

you will have to get a rail to run the 1600's. you can pick up a combo from jason at the store.
yes, i fuel pressure regulator will also be needed to help out on the fuel line transition from stock to the inlet on the fuel rail.
and for the pump, people will probably say something different, but i have the walbro 255lph pump for my car and have the equivalent to the to4E or maybe a little bigger ( i have a garrett to4 with a .70 comp and 1.15 div turbine with a -17 wheel) that will be on my large streetport with fmic and powerFC, wideband, datalogger, profec-B, yada yada yada..........

On the other hand, if you produce proof, that will be mud all over our faces. And don't give us some lame comparison of a TO4E running 10psi and a TO4S running 18psi.

ps- I just had to come back and "edit" this post and say sorry to the other guys. I just went back, continued reading the additional posts, and saw that you didn't want this to be a "lounge". But you know how it is when people make ridiculous claims.
