Hey guys just starting to mod my gtr

Thought a good first mod would be a boost controller, was looking at the new greddy PRofec just looking for some feedback on this or any other good models, looking at spending $500 or under ish.

I've started getting used to the power now and think I need a bit more just wondering what some other relatively good mods to follow on with and not break the bank

Thanks guys

What model is your gtr? On mobile, can't see details.

Pfc + tune will net you 250-260kw with boost restrictior pulled out to 14psi. No need for boost controller of any sort really

Dash 7/9 are Garrett 2860 (or 2859's) turbos bolt on for gtr's, do a search on forums for threads relating to them.

No need for baffling while the motor is unopened, just overfill it by half to a litre on top of 4.6L, start worry about them when you rebuild the motor.

Also, couple of threads to read, rb26 dyno results thread, it should give you ideas what to look for power wise with stock turbos and aftermarket bolt on's. It's on top of this forum, you can't miss it, have a read.

Another one is 'guide for 300-330kw gtr' thread - you'll need to search this, search button is your friend.

These threads will cover most of your questions.

And dash 7/9 are not the same as n1 turbos? and what would be the best twin setup direct replacement for good power

Dash 7 is r34 n1.

My choice is dash 9's, I've had gtr's with both -7/-9s. -7's are common and heaps of them are on for sale if you're looking at used turbos.

Both are bolt on turbos, and you'll need r33 gtr or larger dump pipes since you've got a 32.

Assuming that you have all the maintenance up to date(fluids, brakes, suspension etc), that the exhaust is at least 3 inches from the cat back and everything is in good condition...

As stated above, either drill out or remove the stock boost restricter. Will net you 12-14psi.

I would suggest you get a nistune board installed in you stock ecu. It will be cheaper and arguably better than a PFC.

As a preventative measure, I would invest in a new fuel pump too.

From there.... how fast do you want to spend/go?

I no it's terrible, when I bought the skyline I was like nah ill just leave it fairly stock just a couple of cheap mods hear and there. And spend the money doing a rebuild on my s12 sil but the silvia is under a car cover and it's like out of sight out of mind need more power better bits for the skyline hahaha.

Yer maintanance is pretty up to date I think. just had clutch slave and master done and brake master, injector kits, I'll look into the exhaust and start saving for the ecu and go from there. Can anyone suggest a good link for removing said boost restrictor too

As for power I guess eventually 300-350 kW would be nice but on apprentice wage I'm in no rush lol

Passenger side of engine bay is the boost control solenoid. Black vacuum hose going into the side of it. Pull it off, look inside and there is a restrictor inside. Drill or use needle nose pliers to remove.

It's actually on the drivers side in the gtr.

Don't drill it, just use pliers to take them out, look at one of hoses with yellow marking on them, that's where the restrictor is, squeeze that bit if you don't feel you can squeeze the tube, it means the restrictor is still in.

Yes, it's safe to run 14psi on stock ecu, with PFC/nistune, you'll benefit from extra power after tune.

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
