I have an 06 STi and im installing APS Tumbler Deletes, Perrin STi Fuel Rail Kit, Walbro Fuel Pump, BOV, APS Turbo Inlet Hose, Invidia TBE, and GT Spec Coated Headers. I will then be doing an EcuTek tune at DynoComp. What kind of #s should i expect? Is there anything else i should do while im at it? Thanks

very good start but you really need a turbo

I have a sr-55 for sale w/ 2,000 miles on it also instead of the perrin fuel rails get the aps kit

pm more info on the turbo GTSJOE

Talk to Richard at Dynocomp, some of the Perrin fuel rails need modified to work with the APS tumbler deletes (Injectors don't seat properly) And I agree that you need to invest in a turbo... How much Hp are you trying to get, that would be a better question... With the Stock turbo, you can get 350whp with the stock turbo... A Sr55 can get you 375whp. If you go much bigger than that, you will have to change more stuff... I have Dynocomps Viper Killer kit with a DR55 instead of the SR55. It put 394 to the wheels with a base tune on 94 octane...

Why the fuel pump, rails and BOV and no big turbo?

Hello Guys!

First, This turbo is a bad choice for $2095 for $600 more you get the Perrin Gt35 kit bolt on and it will doubble the Hp and torque.

I have this ball of **** of Sr-55 and I put down 337wHp and 331 torque at 93 octane, but for this, I waste around $7450 including the tuner and Dyno.

I'am so upset, this turbo is overrated at the APS website and everyone is getting this pice of ****.

That's my two cents

Thanks
