Hi Guy's,

I have a r32 gts-t and Ive been trying to fing out which would be a great turbo for the rb20, something thats responsive although still good on top end.

I thought of getting a hks 2540 although my budget does not stretch that far :)

Then I found out about the garrett gt28 thats basically half the price and said to be a similar turbo anyway. Apparently its rated at 400-450hp.

Does anyone know anything bout this turbo?

Also does it work any good with the rb20?

Thanks ;)

Mark

Thats cool man, you can see it on this site-

http://www.horsepowerinabox.com/HPIAB2/cat...ategory26_1.htm

Also you can see there are two gt28's one has a larger exhaust housing so its rated at 450hp instead of 400hp :)

They also run internal wastegates so I think there wouldn't be much to fitting, then I dont know that much :D

At least you wouldnt have to screw round wit gettin an external gate fitted.

On the web site the price is just over $2000

:)

just get a HKS2530 very responsive, and you can get a good one for about $1500 second hand all you have to modify is oil feed, water feed and water drain. get one of those silicon bends from the compressor to intercooler pipe and you are done will pull up to 340hp on an RB20.

super responsive and a sh$%load more top end.

the GT28 series on there are also T25 flanges - the RB20/25 use a T3 flange

From what i've heard and seen

HKS 2510 - spools faster,less top end

HKS 2530 - spools pretty damn good and good top end (allrounder)

HKS 2540 - spools later on 4500+rpm and great top end and works well with cams (good for track use)

this is all on a rb20det and all relative to each other, i'm sure u could find a greddy and apexi aswell

feel free to correct me :(

I recently purchased the 400hp version of the gt28. You need an adapter plate made up to go to the t3 flange, and you also need to bear in mind your standard dump pipe wont fit as its a 6 bolt pattern and the garret is 5.

But Morrie from hpinabox has been so bloody helpful to me, I'd recommend him to anyone. Knows what he is doing, and the adapter plate is very well made.

Haven't been able to test the turbo, as engine is being rebuilt atm, but yes it has a 4" bellmouth inlet. And also bear in the mind the wastegate spring is rated at 11.8 pound.

Im looking for street/strip use for my car . so i rekon an uneducated guess for best turbo setup on an RB20DET would be gt2530 garret highflow ? Also i am thinking of doin the rebuild for the RB20 since im an Exv8 head at heart internals are my main stay of an engine still :( is it viable to do a full rebuild for the amount of extra HP u get outa it ? assuming ur running a say 2.1jun stroker kit forged pistons with a gt2530 turbo . What is the comparison to that and the standard 2 litre with just the turbo and intercooler?

I am seriously thinking about putting NOS on the RB20det thats why i sorta want forgeys but 100+hp is alot im thinking i wont need a boost that big with NOS. maybe just stick with the standard internals run a 50hp jet nos system and gt2530 turbo?

Is this a realistic goal ?

I just need some feedback from owners of RB20det's or wise know alls to lemme know ,has any1 done this setup before? and wat power gains do u think are achievable. Preferably i am lookin at about 400HP at the RW .. but ill be happy with 300hp RW with standard internals and no NOS and just the big turbo kit.

Yer so theres alot more into it then wat i said i know that :cheers: just give me a ruffy and ill work with it... Ive found these fourms to be a wealth of knowledge and im confident someone out there has done something like this ...

Or would it be better of just wacking in the RB25det and using that as a benchmark block?

I know most ppl will say GO BIGGER but how easy it that ... If i wanted to go bigger i woulda just got another V8 im after something else this time , any ideas would be extreamly helpful

    • That sounds like an excellent idea. But total self-sufficiency means exactly that. You have no-one else to blame when your system faults out and you have no power for a week or two while it gets fixed. You'd have to go the whole hog and get a diesel genny and all the switchover gear, to get you through such times. And, despite the fact that over 20 years, my system has been pretty reliable**, I have seen so many inverter explosions (or less dramatic deaths), panel and roof JB fires, and so on, over that time, to know that the stuff is the same as any other bulk Chinese manufactured stuff. The failure rate is well above zero - both on the equipment and on behalf of the meth addled installation labour force. And then..... warranty and means of redress against the supplier you bought the gear from. Best I can tell is that only a handful of solar companies are still around within 5 years of starting their advertising pitch. They disappear and phoenix like crazy. So, as per 1st paragraph, I suspect the only way to is go balls deep and spend maybe 2-3 times as much as you might think, so that you have every base covered. Plus, know and understand your gear intimately, so you can diagnose problems, sort them out yourself, etc, etc. Plus, probably have to consider upgrading various parts as the years pass, to maintain compatibility with newer stuff, performance and reliability, etc, etc. Whereas, remaining attached to the grid has an ongoing cost that keeps going up even if you use bugger all power from it. But it does provide the fallback in case of the worst case with your own gear. You either pay up front or as you go, I suspect.
    • Add more solar panels to the array. Call the electricity company and tell them you're moving out... Live off grid electric wise
    • Hi Jasmine. How's the war going?
    • I'm extremely suspicious of the VPP stuff. Best I can tell, you surrender any and all control of your panels and battery to the VPP, because there's no way that anyone could write a sufficiently useful set of "rules" as to how much you would be willing to let out of your export meter at any given time. If one of your main interests is to have enough in your battery every evening to get you through the night without having to import, you could easily find yourself with nothing in your battery at the end of the day, or part way through the night, and then be paying import pricing instead of paying nothing. I cannot see how this cannot come to pass.
    • majority aftermarket is an10 yes, but majority of OEM is An12 r35 OEM cooler lines at close to an 12, the hard line that car uses is almost 20mm  Porsche OEM is also AN12   i figure, if our power levels are close to 1000hp, then AN12 should be a must if many OEM standard power vehicles use AN12
