Ok, ive only recently gotten myself an R33 GTS25t and im looking at modding it a bit, problem is im not too clued up on all the finer points of turbo cars. The first thing will be the 3" exhaust, but now im looking at an intercooler.

Firstly, what coolers can i get that use the factory pipes? (with extensions etc), and are there FMICs avaliable that have the entry and exit on the same side? (i think ive seen them somewhere before, but might have just been a twin entry)

Secondly, if i decided to get a full cooler and piping kit, what size cooler would i be looking at so i dont have to hack up much of the stock front kit? (its a facelift model). And also, for people who have done this, is there a noticable increase in lag?

Any help you guys can give me would be appreciated, cooler dimensions would be a big help. Sorry if this has been covered a million times, i did try searching!

ARC coolers have inlet/outlet piping on the same side.

Whatever FMIC you get, you will have to hack up the behind of the stock series 2 bumper - there's just not enough space.

With my FMIC I don't notice any increased lag.

What size FMIC do you have wink? Also should the intercooler piping be 2.5 inch or 3? The intercooler kit im looking at has 2.5 inch pipe but uses silicon reducers to fit to the 3" inlet and outlet on the end tanks.

there is a thread on page 1 about intercooling that will be worth reading for you.

Just note that with cooler quality, and anything really, you get what you pay for. The cheapest always isnt the best option.

If you dont plan on upgrading your stock turbo a R34 GTT cooler is a good option efficent for 200rwkw. Direct bolton no mucking arround with piping and cheep. Since your new to this either cheekout the R33 tuning guide at the website in my sig or do a search mate

I have the Justjap Type 2 kit. It's 2.5" piping + end tanks

If you have 3" end tanks, you'll have to chop up even more of the front bar as the end tanks are the things which take up the most space on the bumper.

Just go for a GTR sized intercooler of whatever brand you wish, not sure what the exact dimensions are but im sure someone can tell you.

You'll need to do a bit of cutting into the back of the front bar but it shouldnt be anything too major.

do it right, do it the 1st time buy a jap kit. I have a china/hybird kit and would advise against them the fit is shocking...

ARC,Blitz both have the piping returing to the stock holes.

Hks,Greddy need you to cut a hole near the waterbottle and have the piping running that way.

Im tossing up between a 600 x 300 x 76 or the 600 x 300 x 100 (Gktech) FMIC... considering the car has stock turbo and ecu i think the 76mm thick core is more then enough however i will be going larger turbo and PFC end of the year.. will the 76mm core handle 280 - 300rw/kw??

      just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.

      My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.

      To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
