Turbo Upgrade

[sykotk]

Hey there,

Hope everyone had a good xmas. I must apologise for my absence but I having been working a shitload between two jobs and haven't had much time for the forums lately. I was wondering if someone would be willing to share some advice with me as I'm only new to the turbo scene and to SAU. A few months back I had a dyno run at Willall racing and pulled around 170kw at all four on 14pound boost and Martin suggested that I upgrade my turbo to a HKS 30/37 as it runs well on the rb45. I purchased one from ebay for a reasonable price only to find out that the rear housing is to large to be able to bolt straight onto the standard manifold, so I was wondering what the best option is? Would it be better or even possible to find a smaller rear housing for the turbo so that it will fit on the standard manifold or to get the standard turbo hi-flowed?

You can fit a spacer plate and longer manifold studs. I have done the same with a gt3076r which is the same spec's as the 3037.

You will need ALL the supporting mods to get any gain out of this turbo choice. It would be capable of upto 300rwkw

What other mods have you got and is your car manual or auto and what are your power goals?

What is your budget? $1-2K, 3-5 or 5-10K?

Do you have any mods at all? As Darrin says if you get your new turbo fitted you won't be able to run too much boost without at least a three inch turbo back exhaust, bigger intercooler and some means of tuning it - Nistune chip if your is a S2 (neo) or something like GReddy E-Manage if S1 (unless you have the money for a Vipec) and a good boost controller. That will take you to over 200awkw but then you will need bigger injectors and AFM (unless you have the Vipec where you can ditch the AFM).

Yeah, it'd be handy to know what other mods you've done to the Stag. A 3" free flowing zorst is a must! Got PFC or piggy back ecu? Is yours manual or auto?

I would have recommended a 2530 if its your daily. Bolts straight up, but does require diff lines for coolant/oil. A high flow will be a bit laggy, but looks stock and retains all the original lines.

BTW can I interest you in joining SAU-SA? We have a few stagea owners already ... me being one.

Keep in mind if an auto, the emanage will not work (it will only tune to 1 gear) I learned this the expensive way and now have a haltech ps2000 (even more expensive) and thats why I got to work xmas too.

Emanage ultimate should work ok. Which one did you have?

Hey guys my stagea is a series 2 RS4 with an aftermarket FMIC, xtreme ceramic button clutch, turbo back exhaust with 3" cat, K&N pod, an aftermarket ecu of some sort (im not sure what exactly as the previous owner put it on) and an eboost controller running three boost levels. Not too sure how much i want to spend im just interested to know what my options are at this stage and what the most recommended option would be.

What exactly is it and how do I join?

[Tangents]

Are you still running the stock AFM? Would be handy to know what ecu you are running as well. Also what is your budget for your next set of up grades?

I will try and have a look on the weekend to see what ecu it has and I'll let you know. Budget is probably 1.5-2k at the moment depending on how much more power its going to pull for me.

you'd be better off saving a little more money or collecting some supporting mods first. 1.5-2k is about what you'd pay for a new garrett turbo or even a hiflow. while thats ok for a hi flow as it bolts back in the stock position with stock lines, pipes, etc. with a new aftermaket turbo you'll also need cash for things like, oil/water lines, exhaust modification, intake/cooler pipe modification, etc.

also keep some cash spare for a tune once its on, and if you get up above say around 220awkw you wouldn't be far off the limits of the stock injectors and air flow meter. i just went through a turbo upgrade and all up, with new afm, injectors, ecu, oil lines etc, it set me back about $3500. all labour and mods were done by myself so i saved a bit of cash there.

Don't mean to butt in - but as he's in South Australia - he needs to be very aware of the laws here and what can/will be defected by the police, and picked up by a Regency inspection.

Aftermarket turbos (apparently people get by with high-flows because it uses the same external housing), aftermarket ECUs, boost controllers, turbo-timers, bigger AFMs, bigger injectors etc are basically out .... this ultimately leaves major power-gains pretty much unattainable unless you are willing to risk it and having a fail-back plan to reverse the modifications (with associated labor costs) each time you get sent to Regency for an inspection ..

Adelaide is shit then isnt it...

Meant in the nicest possible way

Hey somehow I missed the post where you listed your mods and the fact that you had a manual. Go for it! Bolt on your GT3076 and get a tune - you should make up to 220kw . But then you have a decision - if you are happy to ignore the laws that apparently obtain in your state then you will need 550 injectors (around $500) and a Z32 afm ($250 - $300) and a fmic - around $400 (or the Trust smic currrently for sale in the skyline section) then you will see around 270kw+

If you want to appear street legal then you could get your turbo highflowed, stick it backon and sell your GT3076 to someone in a less repressive state! ...and then spend your money on brakes and suspension improvements (if you are allowed).

I would very much have to agree with that

Is this a particular kit that you can buy, where did you purchase it from?

Is this a particular kit that you can buy, where did you purchase it from?

the flange that the turbo bolts onto is t3, you can buy t3 spacer plates in different thicknesses and its a standardised size

all you need apart from that is 2 flange gaskets (manifold to turbo gaskets) for either side of the plate, then water and oil lines etc

you have a lot less mods with a highflow, but then the power output is limited (still good for ~18psi tho)

Unless you have a high-mount turbo I doubt the difference would be obvious. you probably lose your turbo/exhaust shield when you upgrade the exhaust anyway...but if you make up another one that'll hide the turbo a bit. All of the things listed above rely on police knowing the difference between stock vs aftermarket (which is entirely possible depending on who you get).

Boost controllers are illegal anywhere in australia, as is anything that changes your emissions. Somehow exhausts are a special case and provided your noise levels are low enough you wont have any trouble for putting an exhaust on.

Turbo timers should be ok provided you dont leave the vehicle while its running...i could be wrong though. Either way they're a waste of money for that reason (if you're gonna wait in your car you can just as easily turn it off yourself when you leave).
