Looking For New Turbo. Questions.

[fabb]

Ok so im looking at doing a bit of work on my skyline. (r33 gts-t series 2) Looking for about 220-230 kw atw. According to my dyno sheet that i got with the car i have exactly 200kw atw. (anybody know is this is decent for a pretty much stock skyline or not?)

I want to put as little work and money into it as possible while still getting reasonable performance. My questions are as follows..

1. Should I get my turbo high flowed or buy a new one? I want it to pretty much bolt onto the stock manifold. ( If so, where do i get new turbo or get my one high flowed and plus how much $$ looking at?)

2. also i will need to change my ecu? or just get mine remapped? once again, where can i get this done, what do i use, and how much am i looking at? btw i am in perth.

3. if i change or highflow turbo, is there anything else i will need to modify for it to run properly?

my mods are as follows..

-full high flow 3" stainless steal exhaust .

-Front mount intercooler

- pod filter

-lowered suspension

- super heavy duty single plate clutch

and thats pretty much it besides boost gauge etc...

any and all help is appreciated!

the problem is going from 200rwkw to 230rwkw or even 250rwkw is a $5k exercise

are you sure you aren't happy with 200rwkw?

a 200rwkw gtst if setup properly is pretty quick and should beat most cars on the street

you cant really get a turbo for 230rwkw, its usually 250rwkw

a highflow or HKS GT-RS will get you there

but then to support it you need

injectors

air flow meter

fuel pump

stand alone ecu or decent remap

so its hard to get any more rwkw without a decent outlay - ie $5k inc the turbo purchase itself

if you really really want that power go for it, but its not cheap

highflow or GT-RS is about the same result

highflow is guaranteed to mate up

GT-RS you can sell your old stocker for $100

but then you may have to play around with exhaust to make it fit

but then you call your friends you have a HKS turbo

both are "new" and no difference as far as reliablity etc

this may give u some ideas

oh so 200 kw atw is pretty decent? sorry im sorta noob.. my previous r33 "felt" quicker , no idea why but defenitly wasnt 200rwkw. What is "Stock" rwkw for r33 gts-t? yeh im happy with my cars performance but would be even happier if i could get a bit more out of it. And i defenitly dnt have 5k to spare. anyway of pushing another 10rwkw? without stepping into the thousdands of dollars mark? Also u say "if u set up properly" any ideas also on how to get the most out of my currents set up?

peak rwkw doesnt make a car quick, average power does

what does your dyno chart look like and how is it tuned?

you can 200rwkw and then you can have "200rwkw"

its all in the tune

stock ECR33 is 140rwkw

the only way to push 10rwkw is to make the turbocharger work harder, or lean out the mixtures, or change your wheel size

most are not a good idea, a stock turbo at 200rwkw is pretty much on the failure level already - ie around 12psi ish

okay i just spoke to old owners, and APARENTLY they gave me the wrong dyno sheet when they sold me the car. they had 7 skylines) and ive only had my car for about 2 months. I knew it didnt feel 200rwkw... new dyno sheet says 201.5rwhp**** my bad BIG rookie mistake. but i knew there was no way it was hitting 200rwkw especially with those little mods. so now my quesiton is.. anyway to push that without having to spend thousands of dollars?

(sorry for wasting ur time on previous questions :// )

You 'should' get a power fc. I got mine with a hand controller for $1000

Then a z32 afm. I got mine second hand for $100

Then some big injectors. I got mine for $500 refurbished.

All that with a bleed valve will get you another 50 rwhp or so but it will stress your turbo a lot more.

Mine made 189 rwkw or 253 rwhp on 12 psi on the stock turbo.

Unfortunately there is no cheap way out of it like paulr33 already said.

if you'd like to maybe purchase my hiflow i might be able to work a deal out with you, mines already made 215kw and would probably make upto 230 and bit more, im looking at upgrading to a gt30,

for ECU recommendations Im actually leaning towards a vipec or an ecu that can take ethanol sensor feedback for fuel map trimming so you can have the 'ANY FUEL' choice in the future...

I have a PowerFC and its fine, but I wish I could use the ethanol sensor and just use whatever fuel is available... that is E85 or 98...

keep doing some reading OP, sounds like you have lots to learn about upgrades and costs....

hey bit off topic sorry, but where do you get those graphics on your car? and is it expensive? looks good

yeh that dsnt sound too bad of an idea but if I do purchase say ur high flow turbo what else will I need to support it besides aftermarket ECU? and how much will labour set me back?

We dont have ethanol at the pump in Perth. Still a valid point tho.

I would take a stab at him getting the graphics from the place that his signature is advertising?

To properly support the high flow from stock you would need computer, injectors, z32 afm, fuel pump, front mount (and oil and water lines?) and it wouldn't hurt to have a decent dump pipe. You already have a couple of these things I see. You cant run bigger injectors or the z32 afm without the computer but you can install the computer and make around 200 rwkw without swapping the injectors or the afm. They will be maxed out tho and for the injectors its not a good thing. My injectors hit 100 percent at 190rwkw or thereabouts

i made 195 with highflow, intercooler, exhaust 11psi, help me buy a gt30... lol i want 300kw
