well im only going for about 220kw

so im sure the GTR intercooler will be ok

the guy told me (who was trying to sell me the package for 2100) said that he GTR cooler wouldnt be any good

but it would have to be better than the standard cooler

where would be a good place that could fit this for me and supply the pipping

On the subject of coolers...all you guys n' gals out there who have FMICs fitted to 32GTT's :

Do you run your return piping (from the cooler) back through the original intake pipe (across the top of the RB20), or do you run it to a forward facing plennum?

I'm wanting a FMIC and I'm trying to work out any additional costs.

Thanks,

Michael

the point we are trying to make here is that running the standard turbo on high boost with the standard intercooler is an in-efficient package where much more gain can be achieved by running a FMIC and at lower boost.

As sydneykid said, the standard turbo has a ceramic turbine wheel which can't hold very much heat for long periods of time, therefore, running the standard turbo in it's in-efficiency range would allow it to push a larger volume of air although at a very high temperature, and given that the factory intercooler is not good enough to cool that hot air, you're not doing the engine a favour.

Also, if u can't hear it ping (even at 20psi), it doesn't mean it's not doing damage. found this out through personal experience.

always make sure there is enough fuel supply and appropriate octane fuel is being used when running hi boost.

You can't run the std turbo on 'high boost' anyway (if by high boost you mean 12+psi).

Keep the stock cooler unless you ugpgrade the turbo or circuit race (I don't think the std turbo will do that for long anyway).

The best intercooler upgrade for the stock turbo is the Trust R-spl core direct factory replacement for about $1k, or an R34GTT one (same dimensions except much thicker). The extra tubing and volume of most fmic's reduce the engine response on the stock turbo.

Ive done some reading on alot of the Japanese kits for the R32 such as Trust, HKS, BLitz etc... All of them make use of the original piping to the front bumper. So they have a length of tube that runs across the length of the core (usually the bottom from what ive seen) to a 90 degree exit end tank.

The good thing about this is that you can pretty much do your intercooler piping for alot less than say Silvia or 180SX owners, with about 1.5 metre of straight pipe and a handfull of bends.

Some aussie kits ive seen (UAS i think) use the stock intake plenum so the pipe goes across the top of the motor, then it goes back across the motor again and down through what i think is just beneath the battery area. This involves much more custom piping. And looks alot less "stock" when cops pop the bonnet.

Personally, im keeping the standard pipes to the front bumper and just extending as required.

Whoa this discussion has certainly changed direction. Lucky for me i have an aftermarket turbo...and i'm running about 12-13psi with the std cooler. Hopefully i'll upgrade the cooler in the next month or so...i know a guy who is selling fmic for R32's for $500, and that's with a PWR core.

who has these intercoolers ?

i have a high flowed r32 RB20det turbo on the said motor running 13psi thru the stock cooler, i find that it just heat soaks and pisses me off... some nites the inlet temp sits at 49deg c

i am lookin for a FMIC.....

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
