Well there is a product coming that will allow me to map it... cant say much about it though.

I trust SFR's fabrication work, I would not go to another vendor for exhaust work in particular. Expecially when I am on the right side on the globe.

intercooler just because you gain power AND it's easier on the engine

I was thinking the same about the exhaust mod... more power, no more stress on engine.

The price/website is 3 years old. He nows sells them for $700 and you won't get 50hp trust me! I know them well.

How about the lower end? Rod bearings? Don't do a cam and high rpms with tired block.

I am not going off the website, I am going off an email from him, $650 using a German billet. and he actually said 25-40BHP on a stock turbo, on my application 60-70BHP if backpressure can be kept at reasonable levels. I still have the email.

While you are at it, might as well mill the head to
increase compression to 9:1. That would help offset
some of the low end torque that you're going to loose
by changing the cam.

J chen,
How much would you have to mill to get to 9:1? I milled fifty thousands and from what I'm told, I'm about 8.4:1 compression ratio. I don't think you can go much more can you?
I voted cam, since its biggest power gain and its something I'd like to see results on. Exhaust would be my second choice.

Go with the SFR stage 2 header and full 3" exhaust.
Better spool up more torque.
Let her breath man !!

tconn,
can you show me photos of where you mounted your AMW catch can on a late style car. I have mine sitting around and I'd like to install it but can't find room.

............ but then again Evil is not trying to get $650 from you.

That power gain seems INCREDIBLY optimistic.

........... but I would go with a testpipe.

Yes I agree, but I dont have the experience JME does with cams. I dont think he is the kind of guy to make figures up like other vendors have with their kits. His work is very well respected. I would pay $650 for 30HP.
