how well do they work compared to a front mount want to run about 320bhp is this to much for a top mount (with supporting mods obviously)

 

320bhp is easy with a larger tmic

 

320BHP is about as far as you can go with a standard top mount.
I would go for an uprated top mount from then on, rather then the laggy and bumper butchering front mount method.

 

cheers guys big top mount it is any one recommend one.

 

i just got one custom made its a tiny bit smaller than the APS tmic and cost me £411, not bad for a brand new tmic

 

I fitted 01 WRX topmount which worked well once fitted, cost about £250 all in.

Sitting in the shed at present !

 

Do any of the newer STi TMIC fit (or be adapted to fit) MY99s? Are they much bigger than std ones?

BOB`5, yes they can be made to fit.
See `projects` in www.22b.com

 

Oredred an APS one today about £600 delivered looked like the best deal to me as it retains the twin entry set up which i am told is better for spool up should be sweet once i get my new turbo and headers Thanks for the help.

 

Cheers OP!

 

I was running 330 bhp on the standard TMIC before changing to an APS no problem.

APS on the left....obviously


Tight fit

 

Do you have to modify the scoop seal with that. there can't be much clearance to the bonnet.

 

Scott, the top surface area is roughly the same. The difference is in the depth more than anything but the extra is accomodated below the cooler, not above.

 

If the extra is below the cooler, don't the samco (or whatever) fould on the gearbox bracket, as I know they do on a standard MY00 UK set-up.

 

It almost sits on top of the gearbox,yes, but with the P1 there was a fair bit of room which the APS accomodades tightly.

 

The fitting instructions for the aps call for the lug under the intercooler to be ground down. will definetly fit if u use the standard y piece though.
