Racer X fmic vs Process West tmic?

I've read a lot about the PW tmic but can't find much useful info on the racer x fmic. There is very limited info out there regarding the racer x. I've already purchase tons of aftermarket parts over the holidays and am just waiting to install. I want to do a full stg 2 build on my 14wrx, or I guess full bolt on build with the stock turbo. I'm curious as to how well the racer x performs on the stock turbo vs PW. I'd also like to know how the quality is or any other general info about it you may have. ALSO, The racer x has a better price tag, just curious if its worth getting over the PW. I under stand its not needed, but if it performs better I'd like to know. Any one have any useful info on the racer x?

I run a Ebay TMIC and never had an issue. Granted the PW might have better quality welds, but mine doesn't leak and holds 28psi just fine.

This is an easy decision. Process West all the way. Nothing about a stock turbo setup makes a FMIC ideal.

How's the quality look to you? And you definitely gotta let me know how it is once installed and tuned. Hopefully it works out great. There is such limited info on racer X fmic.

I know nothing about the Racer X but, do know I'd slap my moma for a PW! The pro's and con's of fmic and tmic can be argued for days. Personally I'm a tmic guy and would get the PW. Process west intercoolers are top of the line for a tmic and more than enough to handle a stock turbo. It will also be plenty efficient on a upgraded turbo. If you do go that route dont forget the splitter for maximum efficiency.

The wind spliter is included with the PW IC right? its so hard getting any kind of info on that racer x. tempting to purchase but i dont know the risks of running a bad IC.

Also, might benefit you more to wrap the DP and the likes. Maybe even a blanket on the snail.

Exactly, there are ways to combat heat soak without assuming the downfalls of a FMIC. Reflective tape, ceramic coating, More thorough heat shielding (turbo blanket), wrapping your exhaust, etc. A FMIC would allow for greater peak power, though it would hurt throttle response and spool speed, which is the primary benefit of running a small turbo like the stock one. When you get to larger turbos where a few hundred RPM off spool speed are more trivial, then the trade offs swing in favor of a FMIC.

I see your point.. I'd rather keep the faster throttle time on the vf-52 than make it lag. turbo lag sucks. i guess i better add turbo blankets and wraps to my list of things to buy for this car lol. This rout changes my header choice tho. I think im going to just get the Killer B headers from their site so i can have them ceramic coat it. unless there is another site that sells them with the coat? adn then ill wrap them as well. Rather be on the safe side and not risk cracking with the other headers. just going to hate the costs lol. so far those are the only bolt ons missing from my build and ive managed to keep the cost under 2.5k . I was prevoiusly going to get the Tomei ELH if i went the rout of FMIC. But if im going to be wrapping i dont know if those headers hold up well to the heat.

You can Have any header coated. Swaintech is a great place to get coating done. They charge about $225 for a subaru header. Killer b makes an awesome header and so does full race. Full race has a lifetime warranty to the orignal purchaser for cracks or any other defect. A cheaper but still effective option is grimmspeed ported, polished, and coated manifolds with high flow crosspipe. Oem parts so, cracking is nearly non-existent.

I really, really, really wanna say something here, but you wouldn't get it and it would lose it's humor.

Between the full-race and killer b, who makes a better quality header? I looked up the Grimm speed but I don't think they make one for the 2011+ wrx. I read a whole debate on the differences in their materials, but wonder if that really even matters. I'm curious if ones more reliable than the other.
