Hey guys, I've just installed a Front Mount on my RB20DET replacing the stock side mount intercooler - Im now wondering if I should adjust my TurboSmart boost controller to compensate for the increased flow of the new intercooler? Is this increase in flow going to over boost the turbo in any way? Thanks guys.

I wouldn't be running to high of a boost level as your turbo will strugle as it has to provide more air to fill the new intercooler.

Your car should run alot smother as it is breathing properly and with cooler intake temps should have a noticable horsepower increase.

I'd run around 12psi. Other wise you'll be overboosting and end up with exhaust wheel in the cat. :D

:rolleyes:

cameron, there is not an issue of the turbo "having to fill the intercooler". Once it is pressurised the engine still swallows the same amount of air.

The car wont run any smoother than it did before. Why would it?

Scott, generally as you decrease resistance to flow in a turbo system, the boost will run a bit higher. Ideally you need to get it on the dyno and set the boost level whilst monitoring the air/fuel ratios to ensure everything is safe.

Car will run smoother (I'n your own mind of running smoother :D) because it will be able to breath easier. Rather than running 1 bar through a pissie little cooler that doesnt do sh!t. If you get what i mean ?

Yes but running 1 bar of boost pressure through a stock turbo, it will be running out of efficency range wouldn't you think ? To try and keep the pressure up constant at 1 bar it will strugle.

Hey guys,

Just installed the FMIC and it's funny - I was running 12PSI on the stock cooler - didnt change my boost controller or anything and now it seems to be sitting around 10PSI, so if anything I seem to have experienced a pressure drop. I am running my Boost Gauge off the Intake Plenum, I know theres a few place to run the Boost Gauge from, I wonder if the position of the boost gauge has anything to do with my readings?

Anyway, I've got an R33 Turbo to go on it next and then yes, off the the Dyno for a good tune and possibly a re-mapped chip.

BTW my SOP (Seat of the Pants) Dyno is registering a deffinant increase in power especially in 3rd, 4th & 5th. I also fitted some piping to create a Cold Air Induction system so no doubt that is helping it along also.

    • Checked with amayama and nope, the full S2 manual set is not available anymore. Unsurprising, but still disappointing as the ? on availability gave a glimmer of hope.
    • I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.
    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
