Anyone order this yet?

 

i will be just getting the chip...do u know how much that will cost me with the tune?

 

didnt want to bring this back but...

its been a while...
anyone else running a Stage1?
its a catted TBE correct?
any boost creep?
Thanks!

 

My APS 3" TBE w/hiflow cat did not have any boost creep issues, either. Recently my cat broke so I went catless until I can get a replacement. As soon as the cat come off....MAJOR boost creep issues (20-23psi in 4th+ gears)

I would guess that Vishnu's exhaust would behave the same if no cat?

 

thats what I want to know

 

Actually it comes down to which turbine housing you have. Early STis that had the VF39 with the smaller P17 housing have much more boost creep issues than the VF39s that came with a P18 housing from the VF30/34. IIRC, you got your car early, so it has the smaller housing right? In your case, you would need the wastegate ported to run catless.

 

Vishnu Stage 1 w/ ECUtek reflash on an 04:

The exhaust is indeed catted. I get slight boost spiking when it's cold outside up to 19-20 psi at WOT (although it only did it the first few days, so the ECU may have adjusted now). The car is flashed to run at 17-18 psi. Other than that, it's nothing but smiles.

 

D'oh!

I forgot about that one

Thanks!

 

Interesting.

I have an '05 STi with a Vishnu TBE with custom test pipe (yay catless). I have no boost creep at all, and in fact can't make enough boost in the midrange (maxes out at ~16psi). This is with the xede.

Is the p17 or p18 designation stamped somewhere visable with the turbo still on the car?

 

i have the XEDE and a turboXS stealthback... awesome setup...... no boost creep problems

pulls hard and smoothly in every gear.

 

Im not new to the scene, but Ive taken a year off so to say. I have a question, but there's a good chance that its been disected over and over already and I just havn't read about it yet... sorry

I current own a 2003 WRX and have a cobb stage 2 w/ vishnu turboback setup. Question is, how much different is a turboback setup for an STi? Reason I ask is that Ill be purchasing either an older 04 STi or a new 05 shorlty, and Im wondering if it would be worth my time to strip the turboback and have the ecu flashed back to factory before selling/trading my WRX.

Thanks ladies/fellas....

 

depending on which turboback you have from Shiv, the signature series with the cat in the downpipe will not work with the STI, the cat cannot clear the tranny

iirc, the other exhaust will fit with no issues

 

The signature exhaust was modified last month to fit with both the STi and the WRX. We just had to rotate the cat and move the wastegate bypass tube a bit

Thanks for the replies! I do have the signature series turbo back, purchased about year and a half ago. Considering that revisions were made recently, is it possible to use the old system with the replacement of a few pieces? In otherwords, is it possible for me to purchase a new down pipe/cat/intermediate and use the preexisting muffler portion or something to that effect?

All things considered, it probably does not really matter anyway, cause Ill likely sell the vehicle as is, but chances are I will never get what I want for it.

Thanks for the helf!
