Sizes for intercooler pipes

[mac30]

Has anyone got pipe sizes and the amount needed to connect a GTR cooler to a R33 GTST. Would u also recommend the type of clamps, rubber or anything helpful in terms of installing the cooler urself.

Thanks for ur help.

Just did my own last week, ive got an R32 cooler which is slightly bigger than the R33 one, but the out/inlets are the same size, they are 3", but i got 2.5" piping from then on, i just got the 2.5" pipe enlarged at the tip to 3" and welded a 5cm extension of a 3" pipe to connect up to the cooler. bought 3" hose from Pirtek and some T-bolt clamps.

I doubt very much you could fit a pipe bigger than 2.5" as it wont fit between the fan and the timing belt cover, unless you have a modified intake plenum, then you could go 3" all the way...

All up it cost me $350, for stainless steel pipes, clamps and hose, did the rest myself

good luck...

Thanks for the info jnr32r. Would u b able to get some pics. How did u make the measurements for the piping. Did u get rough estimates then welded pipes together. How many bends did u need and r they all 90 degree bends. Wats a good type piping would u recommend (not looking for show but effiency)?

2.5" Piping flows enough without restriction to around 650bhp.

hey 2 1/2" is great

Hey Joel I think 650hp is easy

makes you wonder why people use falic 3" .........

What type piping should I be looking for (material wise that is). Am looking for gradual build of power, would anyone recommend a plenum so future cost is reduced.

Stainless is nice but more expensive.

My FMIC fits behind the standard front bar yet will handle and be efficient up to and slightly over 580Hp or 430kw.

Depends if you want a sleeper or if you want to show off your fmic.

That uses 60mm inlet and outlet. If you use the standard IC piping that is 62mm. 63.5mm piping that is 2.5" will give no restriction to around 650bhp.

There are pics of the fmic on my www site.

What happened to your 2 inch piping mayhem :eek:

[MrMayhem]

mines always been 2 1/2"

I assume your talking about the 2" on the blue s13 which is perfect hes got no desire to make over 400hp and didnt want extra mass to compress to numb its throttle response in a drift.....

Could somebody provide me with measurememts of the piping or the amount of bends so as to assure I have the right amount of material needed. Or whats is the correct way of making the measurements.
