Want To Mod A R33 Gtr!

[glaze]

Hey guys,

Well after having my R33 GTR for 4 months, with it purring along beautifully and without a hiccup, I am wondering what mods I can do to get the car with a reliable 250-275 AWKW. I built a R32 Veilside Widebody GTR last year to 330 AWKW but I dont want to go that far and lose any of the reliability the R33 has.

What to do??

Turbos, Power FC is what Im thinking but what other mods will I need to support 250-275 AWKW or can the stock RB26 engine handle this power without too many internal engine mods??

Any info and advice would be greatly appreciated.

Cheers and Merry Xmas!!

best to hit up the forced induction section mate.. you can check out the power figures and mods used then can decide what you need from there..

the threads are stickied so easy to find

Do a search and I'm sure you'll find something useful/helpful. At 250awkw, you might even get away with stock turbos. But then again to be really safe, yes turbos would need to be changed + pfc and a boost controller. Thats pretty much all you need or all that I'm running.

Full exhaust system / High flow cat.

Boost controller, Adjustable cam gears may help.

hey mate,

as the others said, look on the Rb26 dyno thread in the forced induction section, its a sticky, will find it very helpful,

im currently gettin work done on my R33 GTR, wil be hoping around 230 to 250 awkw,( standard turbos at 0.9 bar, HKS cam gears, gates timing belt kit, front pipes, high flow cat, 3 inch catback, power fc, boost controller, project mu brake pads)

just an indication as to what you would need for 250awkw+ safely assuming your car is stock now:

1.) You can run standard turbos but if you run them above 1 bar they wont last long as they have ceramic wheels, could be potentially dangerous coz if they blow they sometimes send bits of metal into the engine as well then you will need to rebuild the engine as well, hence i am only running 0.9 bar to be safe. standard from the factory r33 gtrs run 0.8 bar (around 0.84 to be precise)

anyway yeh if you wana be safe and have room for more reliable power in the future, i would recommend HKS 2530's, wonderful turbos they bolt on , you wont loose that much response either, i think around 3K mark brand new,

2.) Nismo AFMs, again you can get away with standard afms but you said you want to have a reliable car, then better be safe then sorry.

3.) Air induction kit, apexi ones run around 800 dollars and you can hook them up to the aftermarket AFMs 60mm nismo ones or 80mm Z32 ones depending on which ones you get and what kit you buy

4.) full exhaust - the exhaust consists of a few components, the dump pipes from the turbos, then the front pipes , then high flow cat and then finally the catback. you could buy them all from on brand e.g. HKS or you could seperate brands and save money . Just an indication of prices:

- HKS dumps ( i would buy high quality dumps as theyr structure can affect performance alot) : $800

- Front Pipes many brands available i chose JustJap ones coz theyr cheap and designed pretty well : $329 shipped or $650 for Blitz ones shipped

- High flow cat many to choose from factors to look for include the cells etc which affect airflow - about $350

- finnaly catback 3 inch atleast - most expensive component many brands on average a good exhaust system will cost you $1000 you can find them second hand cheaper, also depends what type you get, me and brandon have titanium exhast systems which are very pricy around $3K mark, but imo not worth the money, HKS Hi-Power $1100 or kakimoto ones for around same price.

4.) Electronic Boost controller - to control what boost you want to run, you can get them around 350 dollars again depends on brand etc, or if you want you can buy the Apexi boost control kit with the PowerFC and run boost from the handcontroller (pm me if you want one im selling mine)

5.)Power FC - aftermarket ecu good for tuning, order from japan around 1000 or find them second hand, i got mine second hand from a guy on the forum, regularly for sale

6) Aftermarket Cams - these will help power delivery and response, 1200 for Tomei Poncams.

7) Cam gears - help with tuning and allow finer tuning compared to factory items - $600 brand new HKS or Tomei or OS Giken. also would be worthwhile considering getting Gates timing belt kit coz youl save on labour as the work involved for cam gears overlaps pretty much with timing belts, these belts are 300 times stronger than factory and car wil run smoother

8.) at this power stock clutch will last depending on how you drive and its condition, but to be safe get an aftermarket one, you can get you current one rebuilt by the reputable Jim Berry and a few others in australia , or get something from NPC again australia i think around 1K mark, or you could get Nismo Twin Plate , very good clutch form what i heard for around $2000.

9.) Injectors - again better be safe than sorry, prices depend on what flow injectors you want, if you want room for a lot more power in the future 1000CC injectors will be a one time investment and you will never need to get injectors again, or 700CC to 800CC will do fine as well for 300KW, around $800 plus for SARD or other brands.

thats all i think of right now, like i said before, you can cut many items of the list for 270 to 300kw, but you said you want reliablity, then if you get all these parts you will not have to worry about a thing and engine will run safe, also might wana consider performance brake pads, people often mods theyr cars and forget about important aspects such as braking, remeber its jst as important to brake as it is to accelerate if you know what i mean, i got my Project-MU B-Spec pads all 4 for $550 delievered, also slotted rotors depending on how much you wana spend. i would also recommend running atleast 255 tyres all around to get good traction. service every 5000Ks with fully synthetic oil, Motul or Royal Purple

Everyone else pleae feel free to correct me if im made any mistakes, but this is what i think would get you a very reilable 300AWKW+ R33 GTR,

hope my post was helpful

cheers

250-275 - is pretty clear. your list above is long... and expensive.

You don't really need

Cams - 1200

AFM - 650

Injectors - 800

That is over $2500 saved that is not 'critical. If all the factory ones are fine in good working order. If the car has been treated well, there should be no issues with anything.

The only thing i would do is swap out the turbos for Garrett -7's. They are basically steel wheel stock turbos, so 280rwkw give/take, not a lot of stress and car will feel virtually factory just without the risk of failure which is never a good thing.

anymore than 250rwkw is danger on factory turbos.

You could even get away with the factory ECU without reliability problems - but car enjoys a good tune - makes the car much nicer

+1

You might want to consider -9's (similar to HKS GTSS) if you want to raise your power target about that...

Even better still, save some more dollars and get the actual HKS GT-SS kit, comes with all the extra bits you need. Good for 300+KW if you decide you want a bit more than your original goal.

I'm in the process of installing a set right now, and it's nice not to have to go hunting for gaskets, copper washers etc.

And it's refreshing to see a new owner who doesn't want to know how they can get their GT-R to make eleventy billion horsepower.

[R31Nismoid]

GT-SS kit is not worth the $$ ATM.

If he only wants 275rwkw as his posts states -7's are the choice, not -9's

[GT-R32]

I bought my -5s off Kudos (forum sponser) with the install kit and it there was no trouble fitting them up with what was supplied, so that is perhaps an alternative (turbo choice pending) to the full GT-SS kit.

My car made 293awkw in 34 degree heat on ~17psi. It needs injectors for more.

[R31Nismoid]

-5s are a waste for only 300rwkw.

If you are not planning on 400rwkw - then forget using them. I wish people would accept this!

-9's will give you the same power, and be super super responsive. Why have more lag for no reason?

[bigmikespec]

I have an ECU and cat back and am making 250kW at 11psi, the tune is nice and safe to keep things going. If that is as much power as you want then you can't go wrong and it won't cost you a lot.

I agree, you make this point very well and often! If 300kW at the wheels is your final aim, smaller turbos are more responsive. Once my motor is built later on, I will shoot for more. My car made 306 at all four, but it ran out of injector. If it had more it would have been boosted until it made no more power LOL.

There's also the differences between dynos (my car made the same power as the black R34 GTR on here), plus I am 600m above sea level and it was hot (not sure how shootout corrects for this), and most of all my engine has 150+kms on it probably LOL. All may be factors for the low number on that boost? Anyway, in due course we will see what my set up does with a new block, in the mean time I am more than happy with the power and boost threshold as it is having had a history of big turbo cars
