Pre Throttle Boost Source IC vs. Turbo Housing

[cait sith]

My EVC5 needs a pre throttle boost source, and my FP3052 isn't drilled/tapped for one, which has caused some uh, relatively interesting throttle response when T'd off the BOV line (Aka don't do it).

I was looking around and some people say that doing the j-pipe for a boost source is OK.

I'd rather NOT have to drop the turbo or drill/tap the turbo while it's mounted, but if it's really that much better than the intercooler pipe (pre I/C), I'll do it, but I don't think it's that great?

I'm almost ready to go buy another Hallman. Ugh.

I think tapping the j pipe right after the turbo would be fine. Much easier than dropping the turbo and having to tap the compressor housing.

Thanks, I think I'm going to grab a cast elbow and put the port in there. I can always take it out if need be as well.

Cheers!

You dont have to really take the turbo off, just the compressor housing. Usually they have a big C clamp or a few bolts. But yes as close to the compressor cover as you can get would be better.

Speaking of which, what's the diameter of the outlet on a 3052, is it 2.5"? I don't have access to my car at the current moment.

The diamter is a 2" out, generally you're larger sized turbos (T3/T4 type) will run the 2.5" out with a 4" in.
