Hi all,

After many years of modifying commodores and old holdens, I'm finally making the move to a skyline.

I've been looking at some r33 GTR's. I have my eye on one in particular, its neat clean and no mod's.

After test driving it I was surprised how mellow the gtr really was, as being the king of all cars, maybe I was expecting to much.

This has not detered me at all as I know the potential of the gtr's. And the gtr I drove was completely standard.

I'm researching my options to start mods as I'm considering the difference between buying an already mod'd gtr instead.

What I'm after is sumthing eye opening, something that will smoke majority of the young commodore driving hoons and still be reliable enough to drive everyday.

So tell me how far can a standard rb26 go. Thinking of upgrading turbo's (as research tells me standard turbo's are not ideal for more boost than factory setting), Intercooler, and a ECU and tune.

What would you giys suggest is a good upgrade and good guidelines to follow?

Buy one already modded. To replace turbos its basically an engine out job. Ive built 1 big power rb26 419kw bg money ran 10.98 1/4 mile.

Sold it for half what it cost to build.

Just bought another GTR stock but with steel wheel turboes. Have tuned it up makin 285kw on 18psi. 2nd run at the drags ran 11.7. So that shows a stock rb26 with basically stock everythin can perform very well. Not many young street commodore hoons can run under 12sec 1/4s

Work out how much you want, what your budget is...

Then read that thread and workout the costs based on the parts required.

You'll soon see a pretty regular theme with either Garrett -9s or Garrett -5's being used depending on what you want (and there is a 10+ page thread dedicated to those turbos already) :laugh:

I don't know but having owned more than a dozen GTRs of every type from 32-35 I can tell you all of them (apart from the 35) are pretty sedate to drive in standard form. they make around 180kw at the wheels standard, and have way more grip than they do power. yes they handle quite nicely and will get around a track quite well but the acceleration feels pretty pedestrian. the good news is that just by doing:

Power FC and tune

boost controller set to 14-15psi (max)

adjustable cam gears (get tuned together with the boost and the power FC)

cat back 3.5inch exhaust

pod filters or high flow panel filter

your GTR will be making around 230-250rwkw and will be running mid-high 12s. plus it will now sound great, and feel much more exciting to drive. that's a lot of extra power for bugger all money. the downside is that to go any higher you will need:

larger injectors

new turbos (expensive and a fair bit of labour too)

front pipes (and dumps too if you want to get the most out of things)

oil cooler

new afms are a good idea (bigger ones)

better clutch (stock one is not good over 230kw really)

some handling upgrades to make it fun to drive with more power

more tuning

upgraded fuel pump

and the lists go on and on. but by now you'll have over 300kw and a very fast car, but it's by no means cheap any more.

personally I'd consider buying one already modded but get it checked out by a reputable performance workshop that knows what they are doing and can spot the poorly modded cars from the good ones.

    • Update for the sake of closure   Ended up getting the intercooler piping all sorted, new plugs and yellow jacket coils, and she was idling mint until it warmed up while I was bleeding the cooling system. Found the misfire to be localised to cyl 3 by unplugging coilpacks, ran a compression test, that checked out, then decided to get a mate to check if that spark plug was firing out of the motor. Upon cranking it over, with the injectors disconnected, the car actually fired and ran on a couple cylinders and heaps of fuel came out the top of cyl 3 I'd say that injector's either spraying incorrectly or spraying far too much, which is fine as I'm planning on replacing them anyway I'm planning on making about 250kW on flex fuel, and have a set of 1000cc injectors from ozautosport, obviously overkill but I'm planning on building the motor and running more boost further down the line, do you reckon they'd be too big for a smooth idle on 98? Thanks for the replies gents, much appreciated
    • I'm confused. You said you want to "remove the clear coat from most panels" but it sounds like you are actually doing a full respray? Few random things to add -  If you chase the blistered paint with 120 grit, I can almost guarantee you'll chase it down to bare metal (that's fine). But if you paint the car from here, you'll have nice little indents where ever the blistered paint was. The new paint won't magically level out the low areas, you need to fill them. Which leads me to the main point I wanted to add, make sure the whole car is flat before you paint it. All those areas with blistered paint you sanded out, make sure to fill them and triple check they are flat with a block guide coat. I'd also check the whole car is flat with a large block and guide coat but yeah up to you if you want to go that far.   
    • 300hp (225kw) is barely outside the standard turbo's range with a bit of extra boost in it (200ish). If you are going to change the turbo you should aim for 250-300kw (330-400hp) to make the expense worthwhile
    • A couple of things, firstly omg that turbo is expensive! $3,000 USD for dinosaur technology is robbery. You could buy a G series turbo and have a good amount of change instead.  If you want a good budget option, have a look here - https://hypergearturbos.com/product/rb25dethighflow/ If you are keen to spend more, have look at the modern turbos, Garrett G series, Borgwarner EFR, etc. Have a look at the RB25 dyno results thread for inspiration.  If you upgrade your turbo to something that will support the 300hp you want and only "probably" have Haltech ECU, your car will only "probably" run. Actually, no it won't run. You are going to need the ECU and injectors at the time you do the turbo upgrade.  No thoughts on "this much boost" as you didn't say how much boost that actually is. Having said that, plenty of unopened RB25's making even more power then what you are chasing.
