I'm almost done with my 2.75L stroker single-tubo build. I am planning on breaking in and tuning the initial setup with 3" mandrel exhaust (I had a lot of the stuff already and NONE for 3.5"), and the factory FMIC. I'm pretty sure I'll be past the 500 whp mark on pump gas and will be running before and after IAT sensors in the intercooler just to check to see how it handles the boost / temps of the EFR 8374 turbo. My setup is based around response and for now will be limited to pumpgas and only 21 psi boost. I am thinking that the stock FMIC will keep up with this demand with such an efficient turbo especially plumbed in single (ie - less radiant and conductive heat on piping, etc).

That being said, I will need an upgrade because this turbo is capable of 750-800 HP later at higher boost. What is available to BOLT IN and fit up in the factory location for piping and which is the best for the money? I'm in the USA.

I have this one http://www.arc-brazing.co.jp/intercooler.html (M079) runs at Suzuka 2 hours nonstop (well once to refuel) and it keeps IAT perfect.

The 100mm ones may take away from response a tiny bit, probably overkill. I removed a Trust 100mm drag IC and response improved and temps were the same. HKS make good ones too.

I am in the middle of fitting a 8374IWG like you from 5s on a 2.8 stroker and it should be easily adequate.

:cheers:

It baffles me why ARC don't make the M109 anymore for the 32-34 GTR's.

Thought they had gone bust...

OK I see they have been resurrected:

as much as I like PWR radiators and oil coolers (I use their radiator).. I'm not a fan of their Intercoolers.. just look at those end tanks.... basic bro science says it doesn't flow that well in terms of efficiently/equally

My untrained and non qualified eye agrees with you. I'm interested what GTSboy has to say.

The GTR coolers they do are probably not terrible. At least the tanks are relatively large and have some shape. They probably look a lot worse than they really are.

The top and bottom tank cooler for R32-3 GTSt is just yucky. Those are a bad idea at any time, let alone when not executed well. Will not bang.

The return flow thingo for R34 GTT is possibly worse. Whilst the return flow idea is better than the top-bottom idea of the R32-3.....the execution is just ridiculously amateurish. Just horrible. The driver's side tank is an abomination of epic proportions

Having said that....I had to build (get built) a new intercooler for my car after the original truck cored one (built last century) was destroyed by an elderly Greek f**ker in an EB Falcon. I got a PWR core. The cores are good. I just got the (return flow) tanks made locally to the same basic pattern as my original.

      LOL.... a good amount of people (not all) on that continent seem to know everything and like to measure things in bananas, football fields, statue of liberties instead of the metric system lol.

      M35 Aftermarket Fuel Pump

      By dawhitehonky · Posted

      I assume the modules are similar enough, so if you've had no issues I don't see why I would. I have tried to find a wiring diagram for the FPCM / fuel pump circuit, but I can't find it anywhere. Otherwise, I would just do some wire cutting and joining at the FPCM and give the 12 V supplied to the FPCM directly to the pump instead. If you know anyone that could help with wiring diagrams, I'd be very happy

      If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.

      Rapid-fire squeaking/creaking from rear suspension

      By GTSBoy · Posted

      Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.

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

      By GTSBoy · Posted

      Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
