Need Some Help With R33 Gts-t Upgrades

[Jake91]

Hi guys ,

I've been having some trouble lately trying to think of some upgrades i can do to my r33 now im not a braniac when it comes to cars, I'm still learning about stuff and i just bought my car about 2 months ago, this is the first performance car i've ever driven and im loving it, Basically i dont have a clue as to what i can do to upgrade it as it has a fair amount of stuff done to it atm, The only major thing i could think of was upgrading the turbo , umm so i rang up turbotech and they told me all they could do to my turbo was change it into a garrett ball bearing turbo so im not sure what he means but i think he said it spools up faster with less lag and can handle up to 28 psi, Now my turbo is small haha atm my boost controller set on high is running at about 16 psi and the guy said if i wanted to put a bigger turbo in it they would have to do alot of work on the engine however he didnt say what kind of work , and also said something about 5 bolt?? something..? cant remember but yea thats when he said the ball bearing upgrade is all he could do at this point.

I was looking at this turbo upgrade turboproducts_listing.ews | Turbotech the Garrett GT30 ,maybe GT35?

These are the current Car mods

Custom M-Sports Bodykit, Top Secret Carbon Fibre Bonnet, GTR Grill, GTR Wing & Drift Wing, Altezza Clear Tail lights, Ganador Carbon fibre Mirrors, GMAX Shadow Chrome 18" Deep Dish rims, Apexi Coilover Suspension, RDA Slotted Front & Rear Rotors , 8000K HID Kit, Custom Front mounted intercooler, HKS SQV Blow off Valve Custom split dump 3"-3.7" Stainless steel exhaust system, Hicas Lockbar, GTR Bucket Seats, Splitfire Coilpackz, Triple Core Radiator, 3A Racing Intake, HighFlowed t3 turbo (Small ), VI-Pec ECU with anti - lag & Launch control (Which are both not enabled) Profec B Spec II Boost Controller, 550CC JEC Side Feed Injectors, GTR Fuel Pressure Reg & Rail, BOSCH 040 Fuel pump, Apexi Turbo Timer, Nismo Short shift kit, Nismo Luminous Dash dials, Cusco Front strut brace, Excedy Heavy duty clutch. Auto Gauge- Boost gauge , Oil temp & Pressure, Water temp Gauges,

Im hoping to possibly kick it up to 450-500bhp? Even more if possible looking to spend money , Any input would be great and maybe some links if you can be bothered , Thanks ~.

Here are a few current pictures

hmmm id suggest enjoy the car for what it is at the moment and do plenty of research!

i wouldnt run 16psi on a standard turbo....

and 450-500hp isnt really a cheap exercise

[ARTZ]

are you kidding most of the work is done all he needs to do is get a 3071 or 3076 and a tune and he has easy 500hp death machine

or if you want something bit cheaper see hypergear...

Search the things i have highlighted , do your homework and

state how much you wanna spend on a turbo...you will be flooded with answers in minutes bud.GL..

ED>..Also search for a recommended tuner in your area...

Sorta agree with both the previous posts..

enjoy what you have, build a motor that can handle power and then throw it all in..

or get a GT30 or GT35, bigger injectors, front facing plenum, wastegate, fuel pump, new clutch.. there is a few more thing you would need.. and then build your new engine while you kill the one you have ATM..

The last option is what i did.. Had a GT35 had 466hp, thrashed it to much timing went out and it was all over.. lol.. got more power out of it.. but it was best on the 466hp..

i think the hypergear thread is a good one to read, as theres heaps of info on there possibly post a question? i agree with stryder, find out exactly what it is you want to do with the car and go from there. for eg. you might want to possibly look at the suspension side of things like swaybars etc. its all good having a high hp car,but making it go round a corner is another thing lol. nice tidy 33 btw

[wolverine]

GT3076 and a tune. Job done.

[tridentt150v]

But maybe more like 400hp, then go RB30 built motor and E85 or WMI and 450-500hp is doable.

Mind you, 400 is lots of fun.

[Harey]

Straight to the dyno results thread would be your best advice.

If your not really into researching it yourself, use this forum to find a great tuner and get their recommendation.

bolt on a GT3076r with 50mm external gate setup and get it retuned on 20psi and it will be perfect 300kw street setup

[tridentt150v]

S what is the car spitting out at the moment??? 200rwkw???

[Jake91]

no idea havn't ran it on the dyno lately.. but last i heard of it was 380-400 HP

[hypergear]

If your goal is around 350~400rwkws you can run a GT3582 in .82 rear with a 60mm external gate.

Use E85 as fuel and run a set of adjustable cam gears that should be able to get you the power without too much lag.

Plus you need a set of valve springs. Lash setup on the R33 suck, they valve bounce uptop with high boost.

[R31Nismoid]

He might not need a set of valve springs at all.

I made 370rwkw @ 24psi, stock head no issues.

Guilt-Toy did 370rwkw as well, GT35 with a stock head and i believe 20psi+

Totally depends on the heads condition as to what you need/don't need. As with many other users' experiences, the RB25 head set-up doesn't suck too much at all.

Either way this guy doesn't have a built motor, so chasing 370rwkw is silly.

Set 400rwhp/300rwkw as a the limit unless you are prepared to fork out for a motor rebuild.

I thought he was chasing 450-500hp at the flywheel.

Perhaps I misread but this is firmly in the territory of the GT3076 and he has all the bolt ons done to support it.

same here...

[hypergear]

I thought he said 450-500bhp. Is that b standing for back wheels? plus "Even more if possible"

[toffy]

i always thought bhp (brake horse power?) was measured at the crank? . OP : do you know what type of high flowed turbo you have (who modified it?)

[Jake91]

yehh brake horsepower.. umm dont know much about it actually. The guy just said it was a "T3 Hi Flow Turbo.. no idea what type tho .. although it does have a HKS wastegate on it.. but yehh not entirely sure.. im not realyl interested in an engine build at this point.. i just wanna know what i can do to it to get some more horsepower out of it and the only thing i could think of was an bigger turbo something like a GT3076 or something..But im not sure if my engine could handle it.. maybe if i took it to the Turbo mechanics they could check it over or something but yeh.

[toffy]

the 3076 seems to be the flavor of the year for std internal rb25 , it seems you have all the supporting mods to fit one , but first before spending your hard earned $$ , find yourself a reputable tuner and get your car checked out to make sure it's fit and healthy

[tridentt150v]

no idea havn't ran it on the dyno lately.. but last i heard of it was 380-400 HP

Based on your setup and the mods you have I'd be thinking more like 230-250rwkw=310hp which could be called 380-400bhp I guess. To go from 250rwkw to 300rwkw is $5K depending on your final preference. Add another say $10K if you rebuild the engine which you will need if you want higher power than 300.
