I want about 250 -260RWHP.
What is the safest most reliable way to get this.
After the Engine components - s5 TII swap(ECU, Harness, driveshaft, diff.)
I will have about $ 2000 for mods


My list of mods right now is


solid engine mounts
lightflywheel
SS clutch
exhaust
intake
rtek1.5
HKS SSQV BOV
FMIC
No emissions.
Dual alternator pulley
I also have an SAFC II





is that good for 250-260RWHP???
I just want it to be reliable and safe.
The simple straight through mods.
PLEASE GIVE ADVICE!!!
My N/a engine is toast. And im swapping the TII and i just want it to be really reliable, powerful and safe.
thanks guys.

I'm not commenting on reliability or anything (N/A guy myself) but it sounds like you'd be close to that. There was a thread with a few examples earlier today or this week, and as they suggested you should check out the time slips and dyno section. Most of the dyno sheets will have a mod list with them, which should give you a good feel for power/mod.

any other feedback?

idsigloo

larger injectors? you got the s-afc so it should work out.

idsigloo

you need a fuel cut controller too

Port your wastegate so you don't have boost creep since yoru using aftermarket exhaust.

Your gonna need either a walbro or an FD pump.

The Rtek has a FCD built in

MattMan002

im a N/A guy as well but im soon to be turbod within 6months hopefully....but anywho im only gonna be runnin 5 and half pounds of boost....im uppin my injectors again and piggy backing the computer and dropping a fmic with T4 turbo blow off valve and a wastegate off the turbo...with all that im only gonna have bout 280hp give or take and thats what the guy said at the rotory shop....

Camrann

a walbro 255 and a 720cc's how much??
but then i would have to get a front mount as well cause id be rasing the boost correct??

AdAm87TuRbO2

I believe that the top mount is good up to 12 or 15psi. If you got the money I'd go front mount, wish I could

adrock3217

Only 280 to the wheels because 5.5 pounds of boost aint ****.

you don't need larger injectors or a fuel pump, would it be in your best interest? yes, i have the stock t2 pump and 550 injectors, i made 240whp as you know. i daily drive it putting on over 500miles a week, larger injectors will just kill your milage, and on my dyno sheet, i was doing ok for my afr. could it be better? sure it could, but you will be fine with stock stuff.

Camrann

i think id rather get a front mount then 720's and a fuel pump

240rwhp is amazing on the stock pump and injectors.

I would not say that is relaible though so it rules it out of the request.

To get 260rwhp on a TII the most relaible way would be a 3inch exhaust and a BNR upgrade like 2 or 3. Then a walbro and 720 injectors for secondaries and a FMIC

Remember you said reliable.
So a bnr upgrade will mean less boost psi per HP. The stock unit runs out of efficiency around 14-15 psi and starts to eat itself. So if you get a upgrade you can run more HP with lower boost numbers.
Then a fuel pump for safety and upgraded injectors because you can then tune them down which is always better than tuning up.

An Rtek may work but an safc woudl probably be the minimum.
A Haltech would get your stuff perfect.

Camrann

haltech is to much. But the BNR upgrade sounds likea good idea.
SO on the the stock motor. I would just need 720's, a walbro255, FMIC and a BNR upgrade and an HKS SSQV, Safc-2 and thats it??

Camrann

I only have to but 2 injectors right?

Here is what I used as a reference

Well the 720's should be fine for a low stage BNR.

I know the stage 3/4 guys are using something like 720 primaries and 850 secondaries or something like that.

If you keep boost low and run a few dyno tests you could probably pull off 550 primaries without any problems.

Camrann

thanks. Very helpful

woops. ALso forgot your on a S5 engine. So your closer to those numbers any way.

My car S4 rotors and S5 turbo/manifolds pushed 180hp/182tq on 8/9psi so I'd assume that at the same psi you'd be around 195-210hp .

So I guess upping the boost to 14psi with an rtek and 720's could get you there.
I'd say ditch the TMIC because heat soak is the killer in the higher hp ranges. Even if you FMIC'd the stock IC you'd be better.

Camrann

Im def gonna go front mount
so far my parts total with engine and all is about 5 grand
ugh..

Camrann

on the BNR upgrade. Im gonna get the stage 2 u just have to bolt it on to the stock manifold right?

You send them your current turbo and they change the compressor side to a bigger one and I think they port your wastegate and may do a bit of turbine modding. They then send it back to you. It goes on exactly like stock.

fastrotaries

you won't need a front mount. Your stock turbo could do that IF it's in good shape. More than likely the answer will be NO, so at least a basic rebuild will be in order. YOu might get away with it with the stock fuel system, but at the beginning of this thread you said safely. So i don't understand why some people would contemplate shortcuts. I got 233 RWHP with a tired turbo, stock motor & I/C. Supra TT pump, Pulleys, E-fan, Profec-B (set at 12 psi). stock injectors (balanced & blueprinted), FCD (Rtek didn't exist), RB 17lb Flywheel, CF dual Clutch, 3" DP to Catback solid pipe (no cats, from thunderfabrications) Apex'i N1 Cat back, TB mod. I could have made more, but the turbo couldn't hold 12psi past 5,100 RPM and would drop to about 7.5psi at the shift of 7.5K RPMS. So there you go. In reality I was ready to install 720's and an S-AFC, but blew my motor, and went with a Haltech Instead...I'm not now happy with the 378 RWHP....without the bottle.

i dont believe the rtek chip will work for u if u have an S5 it is my understanding they only work on S4's! just a heads up, and if u would go with a rtek i would suggest the 1.7 to the 1.5 it will compensate some for the 720cc injectors also as they are requiered with the chip. i have it and love it!!!

why are you saying my car isn't relible when you haven't driven my car? let alone touched my car or seen it? i have not had one thing break on the damn thing. if i have had to fix anything it was the electrical system. the walbro is for sure a good idea, i will be upgrading soon aswell. but i know of a person who was running a hybrid and 13psi, on the stock 550's and a walbro. using a tmic btw with a Microtech ems.
