FMIC with stock turbo's

Recommended Posts

Hi, what are the pros and cons of fitting a FMIC with stock turbo's.

 

Would i get more power?

 

Would anything else be needed or changed to accomodate a Fmic?

 

any problems shortening the turbo's lifespan etc

 

Thanks

If you fit a FMIC make sure it's ducted properly and that your radiator is in good working condition to prevent cooling issues. When you stick a big intercooler in front of the rad you reduce the amount of air hitting the rad significantly.

 

If you do fit a FMIC then make sure it is a good quality one and is ducted so that the air is forced through it. A good condition stock SMIC with the stock ducting will be more efficient than a cheap Ebay FMIC with no ducting.

 

I've just recently purchased a Greddy FMIC from a fellow member to replace my knackered stock SMIC, and I am quite concerned about the reduction in the amount of air hitting the Radiator. How can I improve the air flow through to the Radiator? How can I improve ducting with an FMIC installed.

 

BTW I have an SRD aluminium rad, I've also purchased a APR carbon fibre Slam panel to improve air flow to the rad.

Dont be concerned mate, tons of car run front mounts with no overheating issues.

 

Then again some have overheating issues.

 

I had overheating as soon as i installed a FMIC. However that was due to a goosed rad. The rad even in a goosed state can still provide adequate cooling when there is no FMIC. My problem was solved by fitting another radiator and no issues since.

 

What i'm getting at is, as long as your rad is in good condition you won't have a problem. If your really concerned fit a slam panel

Thanks for the reply's guys. My Radiator is an Aluminium one, i bought it off Lee(SRD), it was only fitted in october and due to terrible weather it has only covered about >800 miles since.

 

I have bougt myself a slam panel, so with all this in mind I should be ok right?

 

When members mention 'proper' ducting for an FMIC, I'm not really sure what that means? Does it mean installing an aftermarket front bumper with a big mouth like the Do-Luck, so more air flows through?

i have a large greddy FMIC. i have no water temp issues. its only a street car i dont track it.

 

 

if you are worried, possibly you could remove the air con radiator, as this is in between the FMIC and engine rad

 

in regards to ducting, i think stock bumper is quite well designed, the bumper allows plenty of air at the FMIC, unless you refer to the little bits at the side to stop air blowing around it?

The little bits at the side are quite useful, yes :) Air will take the path of least resistance, so most of the air going in there will pass around the sides of the IC rather than squeeze through those tiny fins.

 

It doesn't have to be airtight, just some baffling will help loads.

would it be an idea to consider an uprated radiator if there are any issues directly after fitting a FMIC? id like an alloy rad anyway, i could justify it to my bank balance a bit better if it would help any possible over heating if my rad is shot

I fitted a Greddy Spec LS to my Supra as my OEm side mount had seen its last days..

 

I did not find any huge difference with fitting it, but the fins were crumbling badly on the stock one, says alot for Mr Ts 17 year old design..

 

I am also interested in the ducting, reckon its worthwile, the OEM one is ducted if I am not mistaken, mine did not have it though.

I think the HKS oil coolers come some form of ducting as well..
