hi,

i have an MY03 wrx, and am thinking upgrading the tmic. which would be the better one go for? a newage sti or something similar to this:

SUBARU IMPREZA WRX STI 01-06 TOP MOUNT INTERCOOLER TMIC on eBay, also Engine Tuning Parts, Performance Tuning Parts, Car Tuning Styling, Cars, Parts Vehicles (end time 18-Mar-09 09:45:29 GMT)

no doubt the same but different seller

SUBARU IMPREZA 01-06 TOP MOUNT INTERCOOLER TMIC WRX STi on eBay, also Engine Tuning Parts, Performance Tuning Parts, Car Tuning Styling, Cars, Parts Vehicles (end time 27-Feb-09 13:40:22 GMT)

 

Phone the jap breakers and get a v8 sti one ok upto 450bhp, you know what your getting then.

 

What power do you intend to run and do you really need one?

 

was abargin one on ebay for £120 plus postage(sorry to those on here selling for £200)

 

have 300ish bhp at the mo, and would like to be around 330. prob cos thats all the gearbox etc will handle...safely!!

 

The ebay one is a replica, no? doesn't look OEM to me.

 

yeah a replica. put dont know the dimensions or newage to compere core size! to see what has the better cooling affect

 

IIRC i paid iro £350 for mine, came with Y peice, hoses, and undertray (from a jap specialist breaker).

 

if your going for 330 then front mount it, no question about it.

 

What for?

 

On an MY03 WRX, if you are only going for 330 bhp I would save my money and stick with the TMIC. Much beyond that however and there is a definiate case for going FMIC.
Note this is for an MY03 WRX that this advice holds good. If it were a Classic of any description you are already well in to front mount territory. Early Classics were already in need of an FMIC at 280 bhp and even STi 6 needs an FMIC shortly after 300 bhp.
Subaru have improved the intercooling on these cars, model on model since 1993.
In giving this advice, bear in mind that I also sell Hybrid FMICs and have done so for many years.

top mount will be the cheaper option, but fmic if you wanna go for even more power

wiley

 

Note that the ebay link says it should be professionally fitted.
Most Subaru owners are happy to fit their own FMICs

 

so should i just stick to the stock item for my rough power figure??

at the mo it has vf43(yes forty three), 3 inch full system decat, walbro fuel pump, ecutek. next will be to go for pink injectors or similar.

thanks

oh and a fuel regulator.

 

330bhp is what i ran on my std wrx tmic (06 2.5 wrx), but it was at its limit.

 

Had a APS unit fitted to my 03WRX and was very happy with it.
APS Dual Entry Intercooler

 

If you go for a larger TMIC then it might pay you to increase & optimise the feed to it as well.

Which means an STi sized scoop. ( Doesn't have to be carbon like mine )



And a STi sized under tray with splitter & larger rubber skirt. This is my Zero Sport one.





As fitted to my MY03 WRX Stealth Wagon.

Good information there.
Here is a quote from the article.

So those experts advocating the use of STi TMICs are not true experts afterall.

Hopefully, Autospeed will conduct a trial FMIC v TMIC but in the meantime read the results posted in the link at post 12 above. Post 141 on the link thread.

 

enjoy
