If you have a stock turbo the front mount would be a waste for the most part. Even with 2" piping I think the system would have to high of a pressure drop but thats subjective. The stock turbo isn't necessarily undersized for our engines, the problem lies in its age. The wheels have much more drag than a similar modern T4 turbo.
You'd gain peak horsepower with the front mount and have a safer running engine (lower IATs) with the compromise of boost response.

type or talk much?? it may make sence in your head, but its difficult for the rest of the world to read.
money = power, how much do you have?
if i had to do it all over again (i have an 87 Turbo too), i would do a full tune up/inspection and change every fluid in the vehical (coolant, engine oil, trans and diff oil, brake fluid, clutch fluid, etc...) fresh set of plugs, DEALER MAZDA thermostat (i didnt belive that it made a big differnce till i try'd it, definatly worth your 20-30 bucks), lots of other little things etc....
as for modifications after that, i suggest FC3Spro.com. there modification list is right on for the most part. my list is a little differnt and is more for the budget minded
my list:
rtek stage1(1.7) (http://www.pocketlogger.com/index.php?pid=rtek7)
-this is a plug and play ecu upgrade, takes out a few factory bugs and add some usefull stuff. you'll need 720cc secondary injectors for this. ($150 + s/h)
SSAC 3" turbo back exhaust (http://www.ssautochrome.com/search.i...QueryTitle=rx7)
-alot of ppl will talk about build quality etc... but its worked great for me, and i couldnt beat the price shipped to my door. ($300)
Intake
-you'll need an AFM adaptor and cone filter, aswell as a couple bends and couplers. this could very on where you get your materials and what you make it out of. just make sure the AFM sits LEVEL in the engine bay, or it could hampen the sensors effectivness and posibly damage it.
720cc injectors
-depends on where u get them (~$100), the FS section of the fourm is a good place to start looking
Boost gauge
-check out your power snails pressure (~$50)
AF ratio gauge
-really useless as a tuning tool, but can warn you of posible engine damage (~$50)
walbro 255lph fuel pump
-this industry standerd pump will have no trouble keeping fuel to even well moded rotarys (~$100)
MSD 6A(L)
-CDI (capcitive discharge ignition) boxes are optional, but help alot. it made my FC start easier, idle smoother, and made it less smelly (burning cleaner i'm asuming, but who doesnt like a little rotary stank?). (~$150)
finish this and watch the kill list grow
if your still bent on an intercooler upgrade, well i did a fmic with my stock turbo, it works well but there is a little bit of nodicable lag. I would opt for a thicker/bigger cored top mount if i had to do it again, i'm suprized none of the knock off companies have made them yet. idk about what core size would fit under the hood, but a 3" thick intercooler would definatly help i think. probly could get one made at a welding shop for less then $250 including cost of matierials.

I have a huge fmic, with lots of piping to go with it, and there is a definite increase in lag on a stock s5 turbo. I'm going to a bigger turbo this fall, and I see it as pointless to run a fmic on a stock turbo if you have no plans on upgrading your turbo down the line.
And from what I understand, running a fmic shortens your turbo life because your turbo has to work harder.

I run a cheap ebay greddy knock off. For the price it is gona be hard to beat. V mout would be nice but if you cant do the work you have to pay someone to do it.
Alittle boost lag never killed anyone.

If you have the money, spend it on a quality brand of intercooler, namely GReddy. If not then troll the 2nd gen for sale section, there are tons of great deals on FMIC's. I have recently installed an H-FMIC on my car with stock S4 turbo and it works great. True the boost response is slower but not by much and the increase in power from the lower AIT's is very worth it.

FWIW, this is an SRT-4 intercooler mounted in front of the radiator. Its different and seems to work pretty good, stock SRT IC's are pretty easy to come by and pretty cheap. An electric fan is required because the radiator is moved back ~3" and pipes welded and a rad hose that fits and battery relocated. I need a little more ducting probably, but it stays pretty cool.

If you have extra money burning a hole in your pocket, see your local EMS tuner and order a standalone EMS that he likes. You will need retuning later with the upgraded turbo, but at least you can get the engine set up with the EMS and work out all the bugs prior to the turbo upgrade.
You may also want to upgrade your radiator and clutch/pressure plate prior to the turbo upgrade.
This is really only a factor if you are overspooling the turbo.

Air does get to it (not sure how much exactly) but I also 'trimmed' the bumper, but it could use some additional ducting.
My original thought, but my hybrid turbo probably wouldn't fill that core up... Plus the piping would have been twice as long (lag).
My attempt to divert air through rather than around...
I'm not saying this is the best because there are many routes to the 'best' and it really depends on your specific setup.

Best of luck!

i'm not sure, ive dont live near any rollers so its never been dyno'd. some on here have said about 210-220whp with my old setup. My motor and turbo are getting tired, but i've added some more goodies
current setup
-Rtek 1.8
-720cc injectors x4
-3" ssac exhaust
-Xact prolite flywheel
-XTD stage 3 clutch
-walbro 255
-Custom FMIC piping w/ Vmount used as front mount
-E-fan
-MSD 6a
-everything but bac and other air contol valve blocked off
-10-14psi off boost
motor wise everything else is stock, stock housings, stock s4 turbo etc...
all i know is that it starts loosing traction in the upper half 1st gear, but that makes it fun.
