My Car Just Went Bang

[lilcrash]

Yer it's sad isn't it. But I don't feel as bad as when she used to flog me in her celica. That was worse because it was a 1.8na. Atleast the beetle being a 1.8t I have an excuse. Lol

Ok found a good deal, I give mtq my compressor cover and my wastegae actuator and they give me a bolt on gt3076 with lines for $2350.

I think you will be disappointed with a bitza turbo that won't perform like a GT3076 in its native Garrett housings.

[wolverine]

ps. If you are determined to use the factory pattern dump pipe then buy a hi-flow from GCG or Hypergear. It will work out cheaper and you will get decent results.

[lilcrash]

If I'm wasting money I'm not settling for less then 400hp. I have been told to buy a t66 but that may be too big.

I dont think a highflow will be big enough. Has anyone actually been happy with a highflow?

This topic has been covered a lot in forced induction.

A good hiflow is a reasonable option up to around 250rwkw +/- 10kw.

If you want more then the GT3076 is the best bet, making sure you get the portshrouded comp cover and 0.82 turbine housing. (there a few different versions so take your time checking what you are getting).

[lilcrash]

I can get a gt3076 for $1275 delivered but then I still need to add all the extras to make it work, as per the gcg kit for $2950. Gcg do a line kit for $375, and I can probably just buy a Garret exhaust flange and modify my dump. But what size inlet is on them? Will the stock intake pipe fit? And is the 20mm spacer necessary? I just see it as if I can get a bolt on 3076 equivalent for $2350 with lines that's not too bad. Is there really that much difference in the compressor covers?

I was happy with my highflow. It made 245awkw which was quite fast and with a better fmic and nistune would probab;y have made about 260- 270 which is really quite fast (and acheivable cheaper with hyper highflow than GCG). Then I blew my engine and decided to get an RB30 hence the GT3540 although people have had very good results with a GT3076 on their RB30.

I would suggest you get the cheaper highflow or if you really want 300kw get the GT3076.

[lilcrash]

Some one has pointed out that a gt3076 will be rather laggy. Is it too big for a 2.5litre?

Why did your engine fail? Am I dreaming thinking I can push 16/18psi into a stock rb25

I had a HKS GT-RS (240-250rwkw) and have now swapped it for a HKS2835ProS (260-270rwkw). The smaller turbo (and they are very similar) is the pick for cut and thrust city driving and made plenty of power. The ProS is nicer on longer trips and has a very progressive delivery just not quite as responsive down low.

I personally wouldn't go too much larger than these two on the stagea in manual form.

I have a larger framed turbo on the R33 but it isn't hampered by another 400kg.

[lilcrash]

I've narrowed it down to a few options now but here is the 3 options I'm having trouble choosing between. Hypergear ar43 - $1250 + gst and postage, hypergear hiflow - $800 + gst and postage, mtq hiflow/gt3076 hybrid $2350 bolt on.

All should make similar power just not sure what will suit my purposes

[wolverine]

Look at the hypergear thread and go from there.

[wolverine]

I would look at the SS designated model from Hypergear if you are thinking of going that way.

[KiwiRS4T]

My engine failed after hammering on the track. Its not the amount of boost that kills them I think its a combination of oil delivery problems and tune.

You will find 250 - 270 awkw plenty fast enough on the road. Make sure you use a quality synthetic such as Motul and go to some trouble to find a really good tuner.

After looking through the rb25 dyno thread. The hypergear ar43 .83 and the gt3076 basically make the same power, and with a $1000 difference in cost I think the hypergear option is looking good. I always run penrite oil in my cars.

[RS4-S]

sorry to troll but i hate penrite oils, alot of people i know have suffered from bad oil sludging using this oil and had bad oil supply issues (and spun bearings) because of it . if its your daily and you give it a hard time some of the time maybe use castrol edge sport (unless you wana spend more coin and get motul or royal purple).

yeh just my 2 cents, run a flush and change oils.

if you wana stick with penrite then buy repco branded oil because its just rebranded penrite (read the small print) but cheaper.

Just keep in mind the extra weight of the car. I think you should target something that will make 250rwkw without wringing the neck of it (which will still have another 20-25kw by leaning on it). Any less is hardly worth it, much more isn't that usable IMO on the road.

Delivery of power and average power are more important....peak power isn't everything.

[lilcrash]

Just got the reply from hypergear. Atr43 s3 .82. $1480 delivered. The test car made 303 on 20psi. I'm planning on running 14 around town and 18 at the drags. anyone against this? Yer after reading I think 250 comfortably will be fine.

[wolverine]

Tune it up to 18psi and control boost with your right foot. Easy peasy.

Did you get a price on the "SS" version as well?

[lilcrash]

On the website it says it's $400 more so with gst that makes it about $1920. Is there really that much difference?

Just for the record my engine failed with castrol 10-60 in it - not that that was necessarily part of the problem but for peace of mind will now be using Motul 300v instead.
