Which Bloody Turbo?

[ferni]

Who told you that you need to change the blow off valve ? Stock ones are pretty good... There's a GTR on here making over 600rwkw on stock GTR BOVs... the GTSt ones are pretty good as well...

300rwkw+ is possible on stock internals, but it won't last long.. either your mates are lying about having 300rwkw, or thier dyno is reading high, or thier engine is about to go bang very soon ...

As i just mentioned, one dyno may say you have 300rwkw, another may say 250rwkw....

[Quinny]

300rwkw will run 10s in Commodores, a well setup Skyline will do better than that I would think. 250rwkw in a well setup Skyline would probably run an 11 or go close.

If you want 300rwkw, just get the dyno operator to put the temp probe next to the exhaust...

[SPOOLN]

yeah you could manage mid 11's on drag radials i would expect

depends, is stripping weight an option? is it a dedicated drag car only?

will it be street registered?

Its street registered i guess i could pull out the rear seat.

No one told me I know the stock bov is good for that. I said A BOV IS A MUST ON A TURBO CAR....

Mates are not lying was their when the cars were dynoed, dyno is calibrated regulary. Their engine could be ready to go bang true i hope not though. So would it be fair to say that a constant 250rwkw is alot alot alot alot more safer than 300. The answer is obviously yes but is their that much of a stress on the engine putting that extra 50 kw into it

yeah use the shootout mode with airtemp sensor

and just ignore the

Apart from asking a commonly asked question...why give the guy a hard time.

And 300rwks car will spank a 250rwkw car at the drags...thats like sayign a 200rwkws RB20 will be quicker then my laggy 235rwkws...who give a damn about mid range when you have top end and lookimg to run a good qtr mile time. You leave the lien at 4,500rpm and the engine never drops below 5,000rpm

Throw the 30R on it, get a very good clutch, some good drag radials and with plenty of practice you will end up running in the 11s...

Finally someone on these forums that knows what they are talking about, Cheers.

[Roy]

...and lets nor forget. We all dont want the same things form our cars...thank god. If he wants 11s then so be it. If he wants 300rwkws then cvool.

Otherwise we would all be driving R33s with 250rwkws from a GTRS or hiflow...or GTRs with 2530s

I don't know of any .63AR ratio housing for the GT30R but it would be a bit small (as in lacking gas flow capacity) for the compressors performance potential . Realistically you should be thinking of the .82 AR ratio Garrett housing or HKS's .87AR ratio GT30 housing as minimums for that compressor and power output .

Cheers A .

[discopotato03]

Actually my bad , Garrett do make a T3 flanged .63 ratio GT30 housing but trials of this combination in the US

showed up poor results . It worked better on smaller comp trim GT3037's ie 52T and the propper GT3071R .

Cheers A .

LOL, wake up. I read the posts you linked up and the information was vague to say the least. What is the point of having these forums if you cant even ask a question. Dissapointed to say the least.

uh oh! youve back chatted to mussolini!

seriously nismoid, do you have to answer EVERY post with a "STFU and use the search button" post?

lighten up dude. is this a forum or a dictatorship?

that should fire him up.

[R31Nismoid]

Maybe.

But no point asking what others have done IMO

Cant say none of those dont contain the info.

I've read them all, they all do.

3" is not enough in reality.

Anyway, 3037 with .63 will not get you to 300rwkw

Why do you want 300rwkw? Any reason or does it sound cool in the pub?

But my search found a just a couple of results.

3037

I mean this took around 3 mins.

I highly doubt the search button is broken again

If you take the time, there is loads more info which will tell you

Yes Ive noticed this "advice" in a few threads.

Now you posted 15 URLs which require 20 seconds between each search (as flood control is enabled) which equates to something more like 5 minutes + client server lag time + typing search criteria time + scanning results time == a lot more than 3 minutes...

Maybe you should post your search criteria in plain english instead of the URL as it may actually teach people to use the search button.

Also, shen I read this thread I cant believe how many of you did not read the question, rather jumped down this guys throat for stating a clear goal = 300 rwkws.

300rwkw and minimal lag are not possible

cheers

Now my suggestion is a HKS 2835 ProS - while not rated at 300rwkws there are a few people that have done it. Im getting around 270rwkw on an average tune and it has hardly any lag whatsoever and good mid range too and is perfect for street.

Anyway, thats my 2 cents worths ;-)

I used 3037* as one search option

3540* as one search option

The first two, took me about 2 mins. As the same bunch of links was posted last week when this very similar question arose

Then *300rwkw* as the 3rd in my more recent post

Thats all, no bullshit, no tricky options.

One must remember to change the default search days from 30-day to "any date", thats really the only trick to it.

Hope that helps you use the button to its ability

I would decompress the engine if I were you... 300rwkw is fine on a stock healthy RB25, HEAPS of japanese guys have done it. JMS R33 did it for years, my 33 did it no probs BUT the big thing (and this is according to japanese experts) decompress the engine first - HKS 1.6mm headgasket gives an 8.6:1 CR - which is safe accoding to the experts

The 3037S would go close I recon, I ended up getting 290rwkw at 1.2 bar, at 1.4 it made 321. That was with the 0.87 turbine housing, had around 1.2 bar at 4000rpm. When I initially put the turbo on, it had the 0.61 housing, and boost hit so hard at 3000rpm, I never even bothered trying to see what it would do, anything above 1 bar was unstreetable, but with a basic (15 minute) matrin donnon tune it turned out 256 at 1 bar.

3" exhaust will be fine, as long as there are minimal bends and not much else

good luck.

Decompressing the engine is a cheap and good idea, i hadnt thought of that, thx. Is there any difference in the HKS 3037 compared to the GT3037? I thought they were the same its just that HKS are more expensive. Appreciate all the positive comments and the people that actually read my 1st post and didnt try to cut my)throat. To the people that did you made an arse of yourselves

[Steve]

the compressor wheel is different, as is the compressor cover and the inducer - which you can only buy from HKS. The HKS turbo has a split type inducer to prevent surge, and a 0.6 AR compressor Vs the garret 0.7 on the gt30

I have seen a few people try and get the same results from garret gt30 turbos, but none have I seen that can compare, both in how early they come on boost, overall power top end, midrange, infact everywhere - chalk and cheese.

My HKS 3037 was coming on boost with a 0.87 turbine housing earlier than guys I know who were using the gt30 with the 0.63 - with the 0.61 housing on the HKS turbo, boost was hitting very, very hard at 3000rpm - anything over 1 bar and I just couldnt keep traction - in any gear at any speed - it just ramped up so qiuickly. With the 0.87 it was a little laggier, but you could control boost with the throttle. At WOT in 4th gear, made 1.2 bar under 4000rpm all the same.

bottom line, IMO, spend a bit extra

Im starting to like the sounds of this hks3037 with .87 rear. Steve have you had the chance to run your car down the 1/4. I d be happy with 290rwkw on stock internals.

[Munna1]

Im with colour of green on this one HKS 2835 ProS with cams people have seen 300rwkw with this setup with a minimum of lag.
