Probably be something like the 25 turbo was on my 30.. 12psi by 2200rpm! lol

Yep id be happy with that!!!

How was it in the top end?

Its so frustrating trying to get the "perfect" set up. I want to get mine coming on about 1500rpm sooner, so i think changing cams is the go. Makes 400rwkw at 5000rpm now.

Id hate to be chasing something like a 180sx with a 3L and a super responsive turbo through hills though, there's just no chance of catching something like that haha

i dont think cams will get you 1500rpm when .5L only gets you 1000rpm sooner.

i currently have a stock 25 turbo on mine, great fun at street speeds though its dissapointing over 3k and horrid over 5k

is that with a aftermarket computer or the standard one? wouldnt mind getting mine going on the standard one for the moment then putting the aftermarket one in abit later. can do it all now/whenever i want if i really want but would love to get it running again without spending all my money on it.

has anyone used the standard ecu on their rb25-30? sorta worried about doing that coz it might be in the rich maps and wont allow the new motor to bed in properly from running rich. piston rings and glazing the bores and crap like that

aftermarket ECU my RB30 has had an aftermarket ecu since it was installed never used the stocker on it. Its still running the GT35R tune too and runs surprisingly well, no knock issues and the mixtures are good. Havent had to touch it at all, except when it blew a cooler pipe off and was running on 4 cyls, still drove ok like that though go map sensor ecus :P

Imagine something like a 3071 on a 3L. Fkn hell that would be fun

i think a 3071 would be seriously borderline for exhaust turbine flow @ 7500-8000rpm. the 3076 makes a great combo boost starts properly building at 1500 and takes off at 2500 (thats a friends supra (3076 0.82 rear/6boost mani/44mm external gate) but an RB would be similar). maybe you should go something like that on yours steve? it hauls ass out of corners and is so smooth in its power delivery.

Well there's mixed views on which cams for what rpm band etc

Only one way to find out though :P

It would be nice for response and hillclimbs, but i cant go backwards in power. It just feels so good right now, im finding the happy balance between power and response

    • 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.
