Track Day = Fun

[heslo]

Hey guys just got back from Mallala where I had a track day today, my first ever and let me say I walked away like this --->

Only problem, I also walked away with a blown turbo which wasn't so good Now I'm sitting here thinking I could throw a standard turbo back on but hey, that would be boring right? So I thought I might as well upgrade and go for an aftermarket jobbie like a hi-flow or something similar. Anyone got any recommendations? I don't want crazy power, just a nice usable 250 or so rwkw would be awesome; what's my best bang for buck?

[Cubes]

Awesome..

A nice little GT3071r .6 IW-M, spend ~$150 on water and oil lines, $30 on a 10mm spacer plate, $150-$180 on an inlet pipe, $30 on the outlet 90degree elbow and $30 IC pipe extension. $200 for a new bell mouth dump.

The -M depicts the larger flapper that is now available from garrett; it costs $100 more over the std small 1" wastegate.

Bill at ATS can do reasonable prices on these turbo's, better than what GCG do from what I've experienced.

Might also be worth quizzing CRD as they can do some decent prices on turbo's all though they do tend to be on the slow side getting back to you. So don't get too worried if you don't hear from them in a hurry.

An easy 250rwkw with a little more to go should you wish to lean on it a little harder at a later date.

The GCG highflow will get to 250rwkw but it can be a stretch; with cams you can push 260rwkw but only just. However it is cheaper.

-------

I've got a few little things I'd like to do to mine before I take mine out. The usual oil cooler, oil temp, oil pressure and egt guage.

BUT I CANT WAIT!!!!!

[KISIN]

another + for a gt30

[sinistaGTR]

gt3040 external gate.......you know you want too luke lol i have a video for you lol

[Simon-S14]

yeah im getting the 3071r on my 25, cant wait!

[heslo]

Hahaha, don't tempt me Dan!

This 3071r that you boys are talking about, what sort of cost am I looking at all up? Obviously I'll need larger injectors too yes?

[KISIN]

i'd personally get new injectors + fuel pump with the new turbz just to be on the really safe side.

The GT3071 IW (IW saves on ext gate costs and manifold costs) depending on where you get it can be had from 1800-2200.

Give ATS a buzz and see what he can do the GT3071r (60mm turbine wheel) and the .6 rear with the larger IW flap.

Dont let bill talk you in to using one of those ford 5bolt type IW housings as they are not that crash hot.

Be sure to ask for the 60mm turbine wheel version and also the larger IW flap that has an additional M on the end of the turbine housings part number.

With the .6 rear I really wouldn't bother running any bigger than the 76mm comp wheel because if the air can't get out it most definitely can't get in. So you trade the turbo's transient response (due to increased inertia contained within larger heavier wheels) and a little bit of a spool for .... nothing.

There's 2 versions of the GT3076r floating around.

The old crappy .7 comp cover 7blade comp wheel and the newer HKS3037S type .6 port shroud comp cover and 6 blade comp wheel.

The new GT3076 is good for low 300's with a pair of cams or mid 300's at the wheels with race fuel or WMI. The GT3040 has nothing over the new GT3076 apart from a little more lag and decreased transient response UNLESS you run the .8 rear and race fuel or WMI where it does make more power, mid to high 300rwkw's. Obviously that is running with a set of cams, exhaust manifold good exhaust etc etc.

So if you plan on running pump or the .6 rear its really not worth going the gt3040. It used to be once upon a time when the hks3037s core was not available through garrett but now it is...........

Sorry Dan, its only my opinion though. lol

[heslo]

What's the response like on the GT3071's Cubes? Fairly laggy? I'd rather more response than top end power. Remember I don't have a 3L motor to feed the turbo

[RB26GTST]

dont forget metal head gagit too. 1.3mm is the go for the 25. around 400 somalians for this!

just remember too..... you'll need supporting mods like injectors, ecu up grade, metal head gaskit,fuel pump.

dont be tight if your going for a up grade like your talking coz if you do it will only cost you your motor!

my 3 1/2 cents worth!

[sinistaGTR]

wtf sort of bullshit statement is that...the stock one is 1.2mm and is awesome why would you spend $400 on a 1.3mm that will do the same job..... If you were to upgrade the headgasket you would be going for at least a 1.6mm

also cubes...haha gt3040 ftw lol get bit higher hp lol...EXTERNAL GATE FTW

[Luke_ENR34]

just chuck on a t88 or a T51Z SPL

[Nightcrawler]

I love my crappy little HKS 2530 Luke - maybe a 2530 or 2535 might be an option for you - you can pick them up 2nd hand for around $1k every now and then. Pretty much lag free, and lots of fun. I am making 230 odd with my little 2530

[sloutch]

if you want response, a high flow turbo is the way to go although the GT3071 will just be that LITTLE laggier.

[Cubes]

I'd leave the door open to make just that little bit more power.

Having had ~268rwkw for a little while now I can't wait to get it up around 300.

It doesn't feel slow but you do think.. oh what if..

The bug will always bite

I agree leave room for more.

The GT-RS is also a good option to go for response wise and will make around the 260 rwkw mark and be very responsive from low rpm.

I know you luke and you will want to go for the GT3071 as the response is still good and you will love the way it comes on boost and pulls hard and 300 rwkws in a daily is always fun.

I would suggest getting the Deatscheworks that i got from America have seen quite a few people use these now with great results.

Also as has been stated before by Dangerman4 you should go for the bosch 044 intank fuel pump and not the walbro as it has been seen that these have a tendancy to struggle at around 300rwkw.

My 2c

[Adz2332]

Whats the price of both the

GT-RS - $$$$

and

GT3071 - $$$$

???

[heslo]

Hmmm... definately leaning more towards the 3070 option now.... Tried calling Bill at ATS but got the answering machine so hopefully he will ring back with a quote today

You are right though Shaun, probably best to get something with a little headroom, then I can always squeeze more out later when I get bored (which I will)

[salad]

Definitely go the GT3071R over the GT-RS. They use the same compressor but different trims, 52T in GT-RS and 56T in GT3071R (correct me if I'm wrong) except the GT-RS uses the smaller GT28 NS111 turbine. These are only good for about 330hp, but the compressor is rated up to about 420hp. Little point in crammimg more air in if you cant get it out is there?

Just make sure that if you do get the GT3071R, get the proper 60mm turbine, not the cropped 56mm one.
