All the s15s had at least an exhaust, intake and cooler upgrade, one even had 18psi on some turbo - that was a fast s15

Lucky bugger Scott.. I don't quite agree with the s14 having great off-boost torque - I test drove 6 JDM s15s before settling for my R34 and none of them had any torque below 3500rpms lol. Have to rev them hard past 3500-4000 ish and then it hits...and then its good haha.. Driving 2 Skylines afterwards easily confirmed my purchase of the 34- no contest; much more solid all round, the sound, kinda aggro look, interior, the beautiful turbo 6, all of it. Each to his own though. Driven an almost stock 99 model 2 door STi and it was ok fast and instant off the line, but not that fast, good for shooting in street traffic - short distance bursts and fast cornering, nice rocket - still have to rev it like an SR to get torque though. Been a passenger in a lightly modded EVO 3 and that was fast, braking was amazing, sounds horrible, but goes HARD. Looks totally shit. And like the STi, perfect for street. The other car I'd like to eventually own would no doubt be a MK4 Supra though not a big fan of the look - bloated whale/bus/ boat. Much more solid than any Skyline, everythings better except the lack of AWD and handling abilities. 3 litre 2JZ shits over all else, 6 speed box, the cockpit, GT car appeal etc. Just my two cents.

Not really fair to compare a 380rwkw GTsT to a 240awkw EVO ay, how about a 240rwkw GTsT vs a 380awkw EVO - that would be a total rape.. LOL.. You would expect a 380kw r33 to pull away from the 240kw evo though, otherwise it would be pretty embarassing with all that power - I'm pretty surprised the EVO managed to keep up till 140km/h. Meaning on road/ street speeds its almost unbeatable

E85 could be an option since the stock ECU can run dual maps from what I know

G'day..I'm thinking of making a switch from a 290rwkw R34GTT to an EVO 7-9 when the right one comes up at the right price and right time...we will see....Currently running a Precision 5558 on 98 petrol and intending to run the EVO on 98 as a purely street daily car with 1-2 track days a year. Question is -will a 250awkw EVO feel more crazy on the street and give much more excitement coming from a 290rwkw rwd r34?? 250kw because that seems to be the EVOs sweet spot with mild mods and probably 300awkw with E85. I'm not a fan of going sideways, wheelspinning/ going nowhere and looking like an ass - I rather something that hooks up and is gone before everything else and the EVO is one of the best at that, GT-R not an option because they don't offer any value for money. So rather than get into a vs debate, I would like to know what its like going from a 300rwkw rwd to a 250awkw EVO? From people who have made the switch.. cheers R

bump $520 posted - 300rwkw tuned Nistune yep!

All this EVO love makes GTSts /GTTs seem like pieces of shit haha.. Not much Supra love on here? Yep another RWD but a much better one..

Coil packs

If you want 400kw for later then ditch that RB25 and get a 2J Supra, else you will have your money disappearing really fast once things break in the r33. Or have a built RB25 and still waste as much cash. Thats what my plans are for later once I get hold of a nice RZ Supra, not a big fan of the bulbuous looks though..

Putting too much sauce in the turbo will f#%k it up for sure, thats why its laggy- resistance to spin freely..

To test if its the plug, just swap injectors to the next plug? That'll confirm it.

hey MIck, how does your EVO compare to the R33 you had? I know very diff cars, but...your 33 was mental

Mick probably meant full boost on E85 not petrol @4000rpm

bumpity bump

And suspension. After the Bilstein shock/springs, never again to coilovers.

Sauce of the problem?

Agree sell it and buy an r33gtst- that is quite cheap nowadays else go gtr

oh wow is that what it looks like after a few blows, thanks man, will try that trick..hope it'll be ok after

Thanks fellas. I will insert a screw in that hole and try to punch the top in with a hammer, just fear damage that it won't open anymore.. Anyone got a pic of a bashed in bov, so I know roughly how much to 'do it in'? I run 22psi btw, and at 22psi in 3rd/4th it drops and keeps dropping down to 12-13psi sometimes, not all the time - and boost fluctuates 2-3psi most times. Definitely a leak.

All stock and plumbed back, but now its blocked with a pepsi can plate

So you reckon its the bov spring, not the gasket? Can I not put a new similar rated spring on - also if I block that little hole, there will be no boost getting in from the top to hold the bov shut - hence it will always be open/ leak, correct?

Smash my bov? ah no..

Update - blocked off stock bov with a pepsi can block-off plate under gasket. Result- it drives so much crisper, smoother and significantly more down low power/torque now, its amazing - boost comes on very fast (electronic boost controller duty 55 for 22psi, before it took duty 67 for 22psi) - and also much quicker to rev out 3rd to 7000 rpms whereas before it took a long time to reach 7000rpms+. Basically drives the way it should. And yes now I get that expected and unwanted gay sound - a loud flutter/bang when shifting under load. All this leads me to believe there was a boost leak in my bov before - am I correct?? Also explains massive boost drop-off at high rpms from 22 to 12 or 13psi which is my EWG spring rate. And fluctuating boost. AND - the huge lag/ 60% power loss on downshifts is almost all GONE. Yesss.. Chirps tyres under downshifts which it didnt do before. Extensive testing shows there's still a wee bit of lag (say 10% down on power) for half a second or 1 second - very minor and sometimes not noticeable at all. Maybe cos the air charge/boost is now slowed down a bit when releasing the throttle from the backflow since the bov is now blocked. But all in all a positive experience. So do I keep it this way or get a new bov gasket, revert back to the way it was and relocate afm in cooler piping or change my bov intake entry angle in my intake (fabrication) ? cheers Ron

Ah k let me know then

Check timing with a timing light? Easy to do
