On a standard 4AGZE i dont think so,
You would lose pressure due to the length of the coolor/piping even with a big pulley kit you still only get 10-11 psi with a sizeable front mount

huge increase in efficientcy..is that an advantage? think about it..your ic is sitting atop a really friggen hot engine..and the only air it gets is from a 2" if that high scoope..there is not much design so the air can actually flow through the cooler..just hit the top of it..using the FMIC on an ae92 has quite a significant gain..especially if its a good custom core..i have a 400x250x60 front mounted on the ae86 and it works a treat..response is fabulous....use 2" piping.. and a core similar toi that size..tube and fin..custom one..not a cut down factory type..this is where ppl go wrong..i have the stock pullys on mine and with the ice/water spray on a cold 2am morning i see about 10.5 psi at the manifold..
cold air is better than hot air at nearly everything!

cold air also has a much lower volume thus even if the psi reading is lower more air is actually going in. With a higher psi and colder air temp you will be getting shit loads more air into the engine.

Thanks all for the replies.
drift86levin, thats the main reason why I want to frount mount a cooler as its currently really an interheater than a cooler.
I was thinking 2" piping from the SC and 2.5" to the inlet to aid response.
My main concern was that the blower was low boost so a larger cooler would be a big pressure drop but as its giving 8-10 psi, I think I'll go ahead.
Cheers fellas.

not the case..a similar size aftermarket core will do the job fine..as for befor the supercharger, i recomend doing a 4age/3sge throttle body conversion..takes about 30 mins all up to do..the throat itself is about 10mm larger..slightly 'dremel' out the SC down pipe (the butterfly hits) and whack her on with you TPS switch..go for gold! 10hp..FMIC, you'll be laughing!

wow. I didn't realise they ran quite so rich up top, with stock pulley.

You shoudl see them with a HKS or NEVO pulley. Goes rich as crap in the top end.
As for the front mount, i see a .4psi drop (according to the dyno pressure readings) from the theoretical 10psi which the HKS 164mm pulley would normally give me.

that's interesting,
I got a solid 12psi with an unknown brand 164mm pulley and HKS GZE topmount. Before the topmount it would drop from 12psi to 10psi when hot using the stock cooler.

Interesting, maybe i still have a boost leak after all. I thought the 164mm pulleys were 10psi rather than 12psi.

not sure, or maybe your charger is a little tired. My MAP GZE used to make 9-10psi on the stock pulley with stock topmount.

Hehe, quite possible its a little tired, makes this interesting whining/whistling sound, along with a few burbling ones.  I have one port of call left to see if there is a leak. Ill check it out eventually, after i have finished with my 86.

Do you guys think that much of the power/pressure will be lost due to a longer lenght IC piping?
