Getting Rb20 Tuned

I'm thinking of finally getting my r32gtst tuned and since my family is heading down to Perth in a month I wanted to book it in for then.

Currently on the car:

FMIC

Rb25 highflow turbo

Mbc

3.5inch catback

Before I tune what other mods should I get I'm chasing roughly 300whp.

Thinking of:

3 inch down and dump pipe.

EBC? What's a good/cheap one?

Injectors? Gtr ones with resistor pack or what else will drop in?

Bosh 040

Do I need a fpr?

Should I just ask the tuner to supply the nistune board or am I supposed to get that my self?

Also will the tuner be able to fit injectors/wire up resistor pack + fit nistune and tune the car in two full days?

Sorry for all the questions :)

3" inch downpipe and elbow will help yes.

Which actuator do you run on your turbo ? The RB20 one give more boost.

I never runned a standard turbo with 3in exhaust, but you should get 1 bar with a complet 3 inch exhaust.

That's what i was getting on my ca18 with the 3 inch turbo back exhaust and the standard actuator. The CA runs 0.7b stock just as the RB20.

The EBC is not needed if the actuator is beefy enough to get you to about 1b.

As for the injectors, the GTR ones needs the resistor and a "hack" job on the harness. Not a good solution IMHO. Not the one i would choose if it was my car.

I don't know about injectors dynamics, but deatschwerk and siemens have injectors that are drop in. You just need spacers on the fuel rail for the siemens ones.

The fuel pump is mandatory if you want to keep your engine happy and alive. The oem pump is quite old now, throwing high fuel pressure and bigger injectors at it will get you in trouble pretty quickly.

The walbro is a better flowing unit than the bosch 040 in the pressure range we use. And you might find one with an install kit for your R32.

The fpr is not needed.

For the nistune it depends of the tuner.

If you get it through him you can get some sort of warranty for installation and having the thing to work properly. It's always more comfortable if you work on something you've done. If I were you I'll get it through him.

But does he accept to work on it ? He might want to sell you a link or a haltech or anything else. Check with him before to get a quote.

      It depends on what the guy who bought its Ratio is. Mine is a 4.36 Jus Jap told me anything above a 3:9 has equal length shafts which the Nismo center's shafts were not.

      If those shafts in the last 2 photos are the ones that came with the diff, you have no hope of fitting the other ones because they are completely different

      Nismo 1.5 way Stub axle issue

      By OO Dan OO · Posted

      I have recently fitted a Nismo GT Pro Center second Hand buy still in the box i got stubs with it but they are 5 bolt and I need 6 (3x2) I was told by Just Jap that for a 4:36 ratio the stub axles are equal length sku 38220-0V161. They didn't have any in stock but I picked up the ones pictured. The one with 5 bolt are the ones that came with the LSD. The right side went in no issues but the right....I have happened the fk out of it put it in a press and it still sticks out about 5mm too far. It was sticking out about 25mm but after bashing it like Chris Brown did to Rhianna I managed to get it a bit further in but seems stuck again now. Any ideas? Should I just leave it 5mm out and send it?

      Meh. I "see" a typo above, that should have been "sell".

      Nismo copper mix twin “pull” pedal height engagement

      The clutch pedal has a procedure for adjustment. This can only be done after you are 100% sure the system is absolutely free of air bubbles. You must bleed the clutch master cylinder first, then the "separation pipe" which is the clutch damper line, then the operating cylinder as detailed in the service manual. Also, you must fully depress the clutch pedal between shifts. Just because you can't feel it grabbing does not mean the input shaft is truly decoupled from the crank. At high RPM clutch plates are vibrating and moving around, you need to give it the best possible chance of success. On the BCNR33 Nissan revises these adjustment procedures slightly but not by much: I would be careful with trying to play games with these adjustments. As for the Nismo operating cylinder they say a lot of things. In practice the twin plate clutch needs less movement on the clutch fork to disengage because the whole stackup of the flywheel + friction plates + pressure plate is much taller. Personally if you find that the clutch still disengages too high at the top of the travel I would try the Nismo operating cylinder. Make sure to follow the air bleed procedures.
