I am in the process of buying upgrades for my classic.

I will be adding full decat, pump, VF28, and remap.
What top mount should I go for if any.
I am looking for a subtle improvement over the standard one.
Thanks

 

if you have the sti already then i dont think you need to change they are apparently good for up to 400bhp i believe

 

Sorry, I have a UK classic.
My profile needs updating.............but i'm struggling to do it.

 

IMHO for a classic, an STi 8 intercooler upgrade is not worth it, you'll need custom fabrication to get it to fit and the larger STi bonnet scoop and undertray to benefit and you still end up with something that sits on top of a baking hot engine.

For similar money you can have the hybrid FMIC.

Just a subtle improvement over the standard one will do.
What about the JDM one (classic).
Is that a straight swap?

 

Bob if you dont want to go FMIC and dont want the hassle of trying to fit an STi 8 TMIC then you can fit a New Age WRX TMIC which will be easier to fit.

Should be some gains as I believe it is slightly bigger than the Classic.

STi TMIC from a JDM Classic is not worth it in my opinion as its virtually similar in performance than your OE one. Unless you're after some bling.

Other TMIC's are APS and Hyperflow which are massive, will fit better without the hassle BUT are soooo expensive.

By the way I take it this is for your RB5? I'm on the OC Site too.

 

STi8 TMIC is fairly straight forward fit on phase II classics.

 

With all due respect mate, subtle aint good enough when it comes to intercooling; it's either adequate or not! MY99/00 limit is about 330ish, but charge temps are an issue above 300 according to Harveys measurements. I'm not sure if the WRX intercooler will fair much beter!

The STi8 TMIC would certainly do the job if you don't want to go FMIC. Wouldn't bother upgrading otheriwise, many aftermarket TMICS are inferior to the ones produced by Subaru and the really good ones cost a fortune and still have the disadvantages of the TMIC configuration.

^ as NS04 says. Either fit a STi8 TMIC or a decent (Hybrid) FMIC. Both will cost around the same to do, but FMIC will give more headroom for any future mods.

Hybrid FMIC Kits - Subaru Impreza - best prices

 

Pity they didn't test the STi 8 one!

Nice link though

 

It was done back in '02, which explains why they didn't test the STI8
The Tech Features section has some interesting articles.

 

Seems clear to me that he doesnt want to go the FMIC route. Its quite a transformation to go from a standard TMIC to a FMIC.

Yes the Hybrid FMIC is cheaper (I have one by the way) but factor in having to buy an IK, paying someone to fit it and then having to change your insurance details to cover it. It does all add up.

I know someone else with an RB5 that had his car mapped by Bob Rawle with a VF28 and standard TMIC and got 320/320 on Bob's Delta Dash.

Sounds like Bob R wants a bit more performance without going over the top, which all us FMIC's owners started out like. Its all good fun.

 

Yep, I had the car mapped by Bob with the std TMIC too mate (on a VF35), got 320bhp and same torque. Stayed like that for a year. BUT Bob said the TMIC was struggling!

Fair enough if he doesn't want to go FMIC, but at least get an effective TMIC upgrade, which means the STi 8 one in my book! Otherwise your wasting money on something which won't perform any better, and in some cases, may perform worse!

I personally wouldn't go back to TMIC myself now Difference with the FMIC is remarkable!

Agree there too mate. I got 349/337 on Bob's Delta.

Like I said all good fun at the end of the day...
