Can I get 250whp or close to this?
 
With this set up 720cc injectors, fuel pump,Rtek 1.8, 3inch downpipes(no cat), stock turbos and stock IC.

So this is an FC right? FCs only have 1 turbo and we need some more information like s4 or s5. What sorts of boost are you looking at running etc???? I mean making some assumptions I dont see why you couldnt.

it might be possible.

maybe

I think you'd seriously need tuning tools, like a wideband O2 setup and fuel controller of some sort.

It's pushin' it, but it is possible...

fredox19 03-09-08 10:35 AM

Sorry about putting turbo"s" yea it's a 88T2 s4 I just don't have the money right now to get a BNR stage 2 and a FMIC, so I want to see what's the max that I can get with that set up. AS for the psi I want the highest that the stock turbo would allow me to and be done safely. Don't want to be running 15psi if that's the peak of the stock turbo.

What a realistic figure that I should aspect If just install everything out of the box without tunning, one list mention above.

with a S4 you may be able to push around 14 psi on the stock ecu(the turbo wont last that long)I wont recomend 720 injectors on the Rtek 1.8 beacuse the Rtek makes the 720cc injectors act like 550(not enough fuel for this kind of boost),IF you get the 3 inches exhaust(full exhaust)a boost controller to set your boost,some other kind of fuel controller(SAF)some sort of intake to provide better flow you should be close but you should upgrade to a front mount cause at this power levels the turbo is starting to push hot air and you need to cool the charge in order to prevent detonation

I can't tell you for sure, especially since every car is different and I don't have any dyno time yet at all, nor time being around one. But, my best guess if you're running right without a tune you might make 200-210rwhp at around 10psi. That's about what I've heard from others with a similar setup.

Get a s5 turbo and get the waste gate ported and manifold.

chatchie 03-09-08 05:20 PM

Port that wastegate if your gonna run a 3" exhaust as a boost controller will not lower boost, just raise it. Good luck

initial D is REAL! 03-09-08 05:25 PM

if you buy the BNR turbo, it will come ported already

arghx 03-09-08 05:27 PM

it's been done. see the dyno section. you would want Rtek 1.7 with 550/720 and 1.8 with 720/720. Then you will need an SAFC. Or you can get an Rtek 2.1 . Don't get a used Rtek unless it has the stumble elimination fix. See the rtek forum.

If you install the updated chip yourself, like I did, it only ends up costing $10 ($50 for them to send you the new chip, then they refund $40 when you send the old one back).

I just bought mine and was only charged $10 for the new chip and got to keep my old one. When did you get yours?

haltech, fd pump, fmic, rb exhaust, and a tune(ideal) or hitman basemap(10mpg). everything you need for reliable speed.
