Hey guys, just wondering what the best upgrade for my TMIC would be?

I have a MY97 Hatchback WRX with a MY99 Motor installed running a VF34 Turbo 3" Turbo back exhaust. Im fairly sure its just running the standard intercooler at the moment.

Evole.

A lot of people tend to go for MY02 on STI intercoolers, I'm not sure what's required to get them to fit your model but they're generally cheap (<$450) and do a great job.

All GD sti intercoolers are the same size (except Spec C witch has the notch). Get the GD mounting brackets, GD offset clutch resivior, and the GD splitter. Some fiddling with washers and spacers it should fit up fine.

Be sure 100% its a 99 engine as the newer cooler will not fir a 97 donk.

has any one used a process west top mount I'm considering getting one i love the way they look just want to know if they are worth it?

Before any of the other WA people lynch you... yes they work.. how well.. who knows?

There is no conclusive data that PW TMIC are any better than an STI TMIC.

All comparisons have been done between a PW TMIC and the standard WRX TMIC.

After looking into this question a fair bit it seems that the only advantage is that the PW TMIC takes longer to become heat soaked (it will still heat soak the same but just take longer) than the STI TMIC.

Do you have a source on this?

Bar and Plate is pretty poo compared to tube and fin on the efficiency scale..

Bigger does not necessarily mean better.

Yup, every test I have read has shown the PW to be the same as the STi unit. If it was better, I'm sure Kevin would have released something on it.

It is 100 x better than the stock wrx unit, and given the amount of configurations he has they are a good plug and play option. STi units on certain models require a lot of dicking around to make them fit remember.

Awesome thanks guys

That's the biggest upgrade my engine will be getting so was a tie between Sti TMIC and process west TMIC I wanted the pw one as it looks different to the others I've seen but needed to make sure it worked just as well if not better then the one I already had ; )

Thanks for helping

just reading back a couple of pages and its all about sti or pw ic in this thread so don't know how many times its been covered already

on a side note i also thought that sti has less heat soak over pw
