Modifying Gtr

[0zhiph0p]

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

Is it stock currently? If so, don't bother with boost controller, keep $500 in your pocket and buy useful mod like power fc.

[0zhiph0p]

Yer it's stock bassicly has apexi pods turbo timer and exhaust not sure what exhaust full system or just the cannon. I was thinking power fc too. Would a boost controller not get more power than power fc ?

[Count Grantleyish]

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

[0zhiph0p]

It's an r32, power fc sounds like the go then

What are some other mods I should start looking at and saving for do u think

[Count Grantleyish]

How complete is your exhaust system?

Measure it up, 3" minimum is the go.

Start saving for pair of -7/9's, 100k service (if you haven't done already).

I don't get the whole dash 7 9 deal what are they?

And what should I do about oil protection baffles and restrictors and stuff will I need that for a prodominantly street car?

[Count Grantleyish]

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.

Edit- beat me to it

[0zhiph0p]

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

[Count Grantleyish]

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.

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.

[0zhiph0p]

Cool, thanks for your help mate

I'll have a read of those threads

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?

[portaz]

Ahh the eternal question... Leave it stock it's addictive like a drug and more expensive

[0zhiph0p]

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.

[0zhiph0p]

And that's safe to run on with no mods? What's the point of it. And no ill effects of doing so.

Seems like an effective mod double your boost with no money at all lol

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.

[0zhiph0p]

What about with no Pfc or nistune
