I'm not driving the car much on the street anymore- suspension is too harsh, exhaust too loud etc. for it to be very comfortable to drive. Just going to use it for the odd trackday, so not concerned about drivability anymore. If I was, I wouldn't remove the 2530 :)

ok, i might be opening up a can of beans that'll spill into what should be another thread but........ what would be cheaper, if you wanted to have a weekend car, and a track day car..... a worked gts-t, or a worked gt-r, both having say...... 600hp at the engine? or would there be too many variables involved? just running on my train of thought here

Hah now that question deserves a long, opinionated answer...

Depends on size of budget (is $5,000 cheap or is $30,000 cheap?), driving style, access to facilities or contacts, maintenance budget etc. etc. You could write a book on it (I'm sure someone has).

Bottom line (in my humble opinion, and stated a million times in other posts)..

* GT-R's cost more initially, increasing performance costs less, marginally higher upkeep

and the inverse for GTS-Ts. Get a 180sx - cheap to buy, cheap to improve performance, cheap to maintain.

Kinda got sidetracked - as for some dyno figures...

Rick Shaw has a 2540 on his personal car (it's up for sale btw, as you would expect it's immaculate and everything has been rebuilt) and has dyno'd ~230kw at his shop. That was at 1 bar boost - his standard fuel system limited this.

as far as clutch choice goes, a search should reveal all the info you need.

for around 900 fitted got me my extreme single plate ceramic button clutch with sprung centre. many members are using this clutch and its very usable. I think its good for 450hp, which means it should be fine unless you upgrade your turbo again and shoot for over 250rwkw.. then again whatsisname has over 250rwkw and that was his clutch choice too.

evo- fuel pumps are INTERNAL on 33's and yes can still hear buzzing. No std turbo not good for 230rwkw.

for HKS relevance heres my GT2530. i am assured by the supplier (a friend of a friend, who is the friend of the guy who bought the turbo new in japan!) that this turbo has done less than 2000km's in japan, cost me 1800bucks. Took it to ATS for inspection and they confirmed its perfect.

SLY 33, how loud is your 044?

- mine I can only just hear it with the ignition on but engine switched off. I have a nismo exhaust with dual muffler so it just purrs at idle, but I cant hear the pump at all.

I wouldnt be in a hurry with the extreme clutch - mine was good for about 6 months then it started dying. I know a couple of other guys who had problems running just over 300rwhp.

I ended upgrading to a os giken twin, wish I had gone that way in the first place.

Nice score on the turbo by the way, you'd have to be happy:)

the buzings not that loud but when the exh isnt booming i can hear it. During summer when it gets warm the buzz gets quite loud.

Apparently the extreme clutch doesnt like to be slipped, when i got mine i was told that if i tried to slip it each take off it wouldnt last long, and to just let it out and it would be fine. ive had mine about 6 months, lots and lots of launches, no troubles yet...

Steve: The one pictured is a 52T, but I also have a 56T trim. Actually, the one pictured is damaged (turbine wheel) but I hope to get it repaired soon, if it can be repaired. The 56T I used on my EVO4...how can you tell if it's the current or older model???

What's the difference with your turbo? Do you have a pic?

    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
    • Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
