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

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....

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

      M35 Aftermarket Fuel Pump

      By MBS206 · Posted

      Pressure when IDLING, is meant to be 51PSi... So that amperage value needs to go up a fair chunk... I'd personally be factoring for more like 12amp at least on those runs, and at that point you need to hope the already there wiring doesn't drop you a volt or two, as that's a lot of fuel pressure flow drop off from 13.5 to 12V! Taking idle pressure of 51psi, means the pump will be drawing a MINIMUM of 9amps all the time based on your reading of the graph (3bar base, then allowing an extra 0.5bar for boost = roughly 51psi)

      Wanted to buy R200 longnose LSD 3.9 ratio

      By Ben_D · Posted

      Hi all,  I am in the market for an R200 longnose diff out of a Z31 300ZX, or S12 RSX, DR30 skyline, or similar, in a 3.9 ratio.  Preferably a late model one with the M12 crownwheel bolts.  The only easy to find advert for one of these was my ad back in 2007 when I sold it on this forum.  I sold the diff as I had sold the car it goes to, but as it turns out, after 18 years I got the car back late last year, so now I'm looking for the diff !  If anyone knows where to find a longnose R200 LSD with the M12 crownwheel bolts, drop me a line at [email protected] - Bonus paid if soomeone comes up with the original diff (stranger things have happened !).  Cheers   Ben D

      Back for more after 18 years - and where are the longnose R200 LSDs?

      By Ben_D · Posted

      Hi everyone, I used to post here a bit from 2004-2013, when I owned various Nissans, in particular my S12 RSX gazelle, which was sold in 2007.  As luck would have it, after an 18 year hiatus, the car found its way back to me last year, and over the past 11 months I have had the pleasure of restoring it with my kids.  One thing that I am after in particular is a 3.9 ratio R200 LSD for it.  I actually sold the one out of the car here back in 2007 , and it would be incredible if I could track down who I sold it to, so I can see how they have progressed over the years (and to be honest, to see whether I can get the diff back !).  Anyways, hi all and let me know "where are the R200 Longnose diffs all at these days ?  Cheers Ben D

      G35 Control arm and Compression Rods into a V35 Skyline.

      By sonicii · Posted

      Arms will be the same as the G35 or 350Z, but as above, there was a change in the lower control arm where it connects to the ball joint.  That said, you can remove the ball joint cone from your old ball joints and fit them to the new ball joints.  To be honest, I didn't think the ball joints themselves were different. The main ball joint is a bit awkward to replace, you really need to remove the steering knuckle to press out the old one.  Some people have used tools to remove it in place, but it just seemed too hard to get to. If you are going to press out/in that ball joint, then you may as well just replace the bushings in the LCA and the compression rod.  You can buy the compression rod bushing from Nissan, but the LCA bushes, you will need to go aftermarket. Much cheaper than buying the whole arm.

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
