What Turbo?

[BASHO]

I'm thinking I may go for a bit more oomph (R34GTT).

I dont want much and reckon about 190 to 220Kw ATRW will be fine and I'd like to see it by around 4500rpm so I'll be after something that spools up smartly.

Has anyone any idea as to what turbo I'd be looking for ?

I'm not bothered about huge top end at 6500/7000rpm , it's a streeter and I'm not bothered about shit I won't/can't use.

I've read good results can be obtained fron Hi flowing the stocky but I realy aint got a clue what I'm looking for so any advice is welcome.

I'm also not interested in flinging a front mount on it, closer to stock I can be whilst getting what I'm after the more I like it.

The car has an exhaust system that could cope with anything I and ten others could throw at it so the only other thing would be what engine management ? I was wondering if an SAFC might be enough ? or a reflash but where from ? I've read shitloads of stuff and am none the wiser.

190rwkw - stock turbo can do that with nothing more than a PowerFC (or other ECU) and a tune. Couple that with a boost controller and exhaust, done deal.

You do not need a hi-flow for that aim.

Doubt you would make 200rwkw by 4500rpm. More like 5-6k.

Thanks for the replys guys reality check is a real 170 to 180 ATRW would be fine but I'd like to achieve that without pulling 6000+rpm to do it, as this is my first Skyline I'm a bit at sea with what turbo will do what.

I've had a couple of 00 WRXs before and with those I'd just slap on a VF28 a 3" turbo back zorst and an ECUtec tune and and orf I'd go with safe as houses engine and around a quick 180Kws AAF.

I'm sure theres a similar formula for the R34 I just can't seem to find it, I'm not after monster top end power just a quick street spool, the stock propeller seems to start its run at around 3500rpm so I'm guessing I'd be looking for something that starts aroung 2800/3000rpm.

I'm not keen on throwing away the factory ECU considering what I'm after so a flashtune that reverts to stock as a 1st default would be my preference, if such a thing exists ?

Don't get me wrong the car goes very nicely I'm just being a bit of an Oliver.

I'd say a highflow would be a cheap upgrade for your power range. and this http://www.skylinesaustralia.com/forums/Po...ad-t210097.html for your remapping.

You want more response then the standard R34 turbo.

Wow, thats errrr, the strangest request i have heard on SAU.

i'd get a tune with aftermarket management done as that sounds pretty high (i would also check for boost leaks and that the wastegate actuator isn't fouling). although the turbo is slightly smaller on the r33, i was making 14psi by around 2800rpm in my r33 with stock turbo.

the problem is that you are wanting 2 different things which don't really go together. power and response usually require 2 different types of turbo. power requires a bigger turbo, but you lose response. response requires a smaller turbo but you lose power. there are turbo's that will give you the power you are after and the response, however they are a bit of a waste, and going to set you back a bit of coin. to run them safely you would an aftermarket ecu or something like a nistune, bigger injectors, fuel pump, possibly a bigger afm. all up the setup including the turbo is going to set you back quite a few thousand. it will require running high boost levels which will shorten engine life and increase your fuel bill.

what mods are you currently running? there is no point in telling you to upgrade the turbo if you are currently running plenty of stock parts as you haven't even gotten all of the performance out of the stock car yet. so answer the following questions....

what boost are you running?

what exhaust do you have?

i think that is about it. you said above you aren't interested in putting a front mount on. unless you get an aftermarket side mount, you are going to have to as the stock cooler is going to be getting close to it's limit for what you are looking for. it will manage it, but i would be looking at upgrading, especially coming into summer.

personally, my suggestion for what you want is to get a nistune (provided it is available for your ECU), front mount, full turbo back exhaust if you don't already have it and wind the boost up to 12psi. that should see your goal. or be very close to it and you have saved yourself a few thousand dollars of overkill

Thanks for that, where would I find Nistune ? is that the one with an additional/ replacement motherboard ? If it's the Nissan equivalant of ECUtech that could be just the thing I'm after, I'll try a google but any link you could post would be much appreciated.

I'm running stock boost, I haven't put a gauge on it and there appear to be no leaks so whatever OE is, it is, the car ain't what you'd call slow by any stretch of the imagination it could just be a tad sharper if you know what I mean.

The exhaust is a 3" jap dump, a new highflow 3" cat, a 3.5" cat back to a 3.5" jap mid muffler and a new 3.5" Varex rear muffler set to 60% apperture, the muffler also has an internal 1" permanent bypass, it's disgustingly street legal even when at 100% apperture.

I didn't know you could get aftermarket sidemounts do you know who does them ?

I'm a bit off frontmounts as I always associate them with lag (rightly or wrongly) and the kind of power levels I'm just not after + I think it would nean a plenum change and all the turtling around that goes along with that.

Thanks again,

Al.

Thanks mate, I'd do this in a heartbeat if I were in Sydney , but unfortunately I'm in Surfers.

and since you are running stock boost, get yourself a cheap manual boost controller (one of these will do fine- it's what i used) and wind the boost up to around 11 or 12psi (obviously need to get a boost gauge first, but even a $50 drift one will do the job). you will notice a big increase in performance as you will probably be gaining at least 30 or 40kw. and you should be able to run that boost on the stock ecu.

Ok, I got a stock turbo...running a Greddy Emanage, exhaust, electronic boost controller, Pod and front mount then got it tuned...making over 230 KW's easily so you shouldn't have much trouble getting this from your stock turbo...

[Super Drager]

^ Happy dyno me thinks

[JonnoHR31]

very happy dyno

I'm a bit off frontmounts as I always associate them with lag (rightly or wrongly) and the kind of power levels I'm just not after + I think it would nean a plenum change and all the turtling around that goes along with that.

get a frontmount, with a stock turbo and a manual boost controller you should see 12-13psi by 2500-2700 under load. hardly "laggy"

dont need to change plenum to run a fmic

[Shiraz200SX]

the plenum is the least of your worries.

FMIC are always associated with lag for some reason, maybe in the 1980's with dinosaur technology it was the case...

i put a blitz FMIC on my silvia and didnt notice any extra lag, but heaps more power.... the miniscule lag is far outweighed when you make 20-30kw more.

230... not likely

[mad082]

spunky munky never said what boost he is running. so unless you know what boost he is running you can't say that it is a happy dyno. i know a few people with r33's getting up around (and just over) 220kw on the stock turbo (different dynos in different states), and it is smaller than the r34 turbo.

[R31Nismoid]

Ye but go get them to run the cars on the 1/4 mile and they will never get near 110-111mph that is 220rwkw worth.

Its always lower, indicating the real world of 185-200rwkw
