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??

      I like it when the counter chick leads you out the back into the racks and says "have a grub around in here and see if you can find what you need. I'll be back in a few minutes. Just left me in front of a massive motorised shelving system and 2-3 million fasteners, so I could find a peculiar SS shoulder bolt with cap head. Gotta love country towns.

      I used this https://osgiken.com.au/product/os-giken-os-250r-lsd-gear-oil-80w250-1-litre/   shut my nismo 1.5 pro up by heaps…. Not silent though. Gives the car character and personality. It ain’t a carolla. If you want silent, put a quaife in it.

      It's about the same time for me from Bunnings, or the Fasteners. My big push away from takeaway food, and gluten in general keeps me away from the Bunnings Snags too! Weather up here, I've been out for two walks today in the beautiful sunshine. Had a few little drizzles, and some wind, that honestly, a tin of beans and I could compete on how harsh she blows Thankfully, being this bit inland, we're not getting anything much really. Will probably pick up a bit more when/if Cyclone Alfie decides to come ashore. A few areas in the GC though, and south into NSW are really getting smashed though! Right now, I'm just annoyed Alfie hasn't hit, as I'm not allowed to crack into the BBQ foods like the bacon and eggs until the Cyclone hits "In case we lose power"...

      I love fastener joints, the price difference between them and joints like Bunnings or Super Cheap is amazing, and they either have exactly what you want, or they can get it to quick They have even given me some for free when I only needed a couple of specific size In saying this, I have paid premium for fasteners from Bunnings if they have the sizes I need, but only for convenience really, as my local is only 10 minutes away, the Sushi joint near them is also a consideration  How's the weather Matt? Stay safe mate

      Wideband is worth setting up if only for tuning purposes. I would not mess with the ignition system unless there's a misfire. HKS crank trigger is popular out here for the relatively easily sourced Denso crank sensor, not a bad idea to install as well regardless of power level on a standalone. Boost leak test is worth thinking about. Oil pressure sensor tied to a fuel cut isn't a bad idea either. Getting the tune figured out is a good idea. Without putting eyes on it and getting under it there's no way for us to tell you exactly what it needs but most likely you're down to the last 10% that will make a big, big difference in how happy you are with the car.
