R33 Gtst, A Few Questions

[vxsr33]

Hey guys i have an r33 gtst which i am hoping to bring to around 230-240rwkw and keep lag minimal.

Current mods are:

10psi boost

Full 3 inch exhaust

Apexi pod filter

Blitz return flow cooler

Gtr fuel pump

Car is making 180atw

Upcoming mods:

Power fc

Bigger injectors

High flow turbo

Z32 afm

so my questions are.

1. Is it worth tracking down a r34 turbo to highflow over a r33 one? I heard the 34 can flow better but is it much laggier?

2. What size injectors should i be going for and any other mods needed to reach this power level.

3. Does anyone know a good tuner in melbourne, located in west suburbs but willing to travel.

Any help is very much appreciated im fairly new to skylines.

1. Not for the power you're asking for. Still well within 21U territory.

2. 1000cc Bosch from Scotty.

[Scott Black]

Contact hypergear about turbo requirements and ecu, scotty for injectors and hypergear can recommend a tuner down there too.

[Cowboy1600]

You're in the right place.

21U Highflow and Adaptronic ECU from Hypergear in Somerton.

Injectors from Scotty.

Get it fitted up in Dandenong at Forced Motorworx and tuned by Trent @ Status Tuning in Keysborough.

The 21U R33 turbocharger is super responsive, that supports an average of 260rwkws on P98 fuel, 20psi @ 3500RPM.

The R34 turbocharger has an larger rear housing that is capable of making more power, handles more timing, we can also high flow it using our ceramic ball bearing system thats brings the optimum throttle response out of it. The turbocharger it self is capable of supporting the 270rwkws region in average, 20psi @ 3650RPM CBB or 3800RPM plain. If you have both turbos available, in my opinion OP6 is an better pick.

Thanks for all the info guys.

I will pm hypergear

Isn't 1000cc injectors overkill though? I was thinking i would only need around 555ccs

There's no point messing about with shitty old school injectors in the 550cc range. The modern Bosch ones will idle better than the crappy old ones even at twice the size. Plus then you will NEVER need to upgrade them, regardless of what you do (within reason).

[vxsr33]

Ahh ok, thanks for clearing that up for me GTSBoy

[Dose Pipe Sutututu]

I like using the unmodified Bosch Seadoo Jetski injectors, although they like to be at 4bar base to be at 1150cc

Guys, I'm new to SAU, I'm actually buying a mates 33gts25t in roughly 3 weeks(cheers tax). I believe he's a member just not sure of his user name.

Anyway, I have a few questions seeing as this will be the second boosted car I've owned, first being a GT forester(let's not get into that) lol.

So basically we've done some minor mods and whatnot to it since I've been friends with him, and we aren't quite sure of the KW figure. Haven't been bothered to pay for a dyno.. Probably roughly 180-90ish

I know it's got the usual tasteful mods..

That being..

*Blitz Return Flow Front Mount

*3 inch cat back

*Walbro 255L pump(I believe)

*NGK Plugs

*Profec B2

Now when I get it I plan to go 3" turbo back.

Any tips or hints on how to get it around 220KW's without spending an arm or leg?

Any help would be greatly appreciated.

Cheers!

Ecu, complete the exhaust, 12psi and that'll get you to the 190-200 mark, and that's the limit of stock turbo

Anymore you'll need to change turbo, potentially injectors and AFM depends on how far you want to take it

[Jetpilotrider91]

I was considering a Nistune.. Not sure what everyone's take is on them but I know they're roughly 500 brand new.

Well it will be sliding at some point, but casually not everyday.

i thought about a 2540 upgrade but I've heard some bad shit about them.

Contemplating going Bosch 500cc also.

Not sure on the AFM though.

[Jetpilotrider91]

Either 2540 or high flowing the T25

Obvious place to point you for a turbo is Hypergear. Look at the Hypergear thread. All of it. The 21U highflow will do up towards 250rwkW. You will need the Nistune of course and it's a sensible choice. It's less easy on R33s but at least it's not as bad as it used to be. You should look into what it actually takes to achieve it (effort and cost wise) then decide if any of the other options make any sense to you (such as an old PFC, or an Adaptronic, to name a couple of options). You will need injectors to make the best use of the turbo. Likewise a Z32 AFM (if you stick with Nistune or PFC).

[Jetpilotrider91]

Already messaged Hypergear. I was going to hi-flow the T25, but on second thoughts seemed to be a waste of money as such.

I'm not sure why everyone leans towards a power fc these days.. Majority of the lads I know that have stageas or skylines always have the fc. What's the difference? Besides the obvious hand controller which gives you all the readings.

I'd prefer to spend less money on a Nistune because I'm not building a weapon that has no purpose of being road driven, as it can't be driven to its full potential, and well having a skyline with a reading of 600kws at a drift meet is pretty pointless, as long as it holds sideways then that's all that matters really.

I've got a mate who is a mechanic and he is RB crazy so I'm pretty sweet for effort and labor costs etc

Probably because Power FC are cheap these days and if you want to Nistune an R33 you have to find a suitable Z32 ecu and set up the VCT control (if applicable).

[GTSBoy]

^ This. I otherwise agree that Nistune is the better choice.

If I had an R33 and wanted to Nistune it, I would sell the car, but a 32 or 34 and Nistune that. Better cars, better ECUs. Better life.

I don't see how a hg high flow is a waste of money. 250-260rwkw on 98 and 300-310 on e85 and full boost by 3.4-3.5k rpm for $850 and is a 100% bolt on affair, no spacers or other bull shit required. I don't believe you will find any other turbo in that price range and unless you are chasing massive HP its a no brainer for most. Hypergear also does excellent pricing on adaptronic ECU's if you buy a turbo from him. You won't require an AFM or boost controller with one of them either, they do all the fancy crap, flex fuel, wb input, launch control and the customer service and support from adaptronic is phenomenol. My 2c.
