goddam that shit is full tilt car porn. *like*

Holy F&*kballs you're a champion. I cant even imagine how hard that would be. nice work...

anybody here about a resolution on this? was the guy/ car identified? was it bad/reckless driving causing the incident?

ive heard this from gates and otehr kevlar belts. Just meant to be the nature of them sometimes and often seems to disappear after a while. I had the same thing on mine immidiately after replacement n took the top cam cover off. It was def not an over tightened belt. 3000km in it seems to have settled down. not to say this is the case every time but gates/kevlar belts can be noisy like this. Def make sure it isnt too tight tho...

i dont know avcr's but do they give a constant display of boost pressure (like the greddy profec's do) if so what are the numbers you are reading? also turbo's dont usually 'rattle' when on boost... many people have complained of a brief high pitched squeek but never a rattle...

he'd better be hoping that he has a clean driving history otherwies that will really amp up sentence... as a motorcyclist myself- f*&k him. I hope he burns for causing shit like that in that kind of way...

im not sure exactly but it seems the GTR motors can throw the bits of a blown turbo into the intake and therefore through the motor. Hence a full rebuild cos you cant throw metal or ceramic through a motor without major damage. just old turbo seals themselves cant cause damage but this is a sign that a turbo is on its last legs meaning you are probably very close to the above situation...

so does it give any specific values or just indicate the general range? also is it very easy to wire up to the O2 sensor?

hey mate, this AFR gauge include the sensor?

doubt it. Its not often that a good manufacturer reduces the power of its flagship sportscar...

Bit of an update to further substantiate this arguement. New BMW M5- will now be a twin turbo V8 (replacing the atmo V10) also strong rumours are that the next ferrari hypercar- eg the F40-F50-Enzo lineage- is also rumoured to be twin turbo V8. oh yes, bring on the boost....

yeah im thinking turbo seals. For a decent bit of machine like this why dont you go get a compression n leakdown test that way a) you can rule this out b) you can be sure that the motor is in decent nick before you decide on how to deal with the turbo issue. i wouldnt wait too long. Turbo failures on GTR's often create damage that requires a full rebuild...

just bought the genuine brand new JECS 550cc side feeds. Look the business- 12 holes per injector! pricey tho... interestingly they look identical to pics of nismo 555cc's. looking forward to these + a GT-RS snail pushing the ponies

cool. n these were genuine 550's n not just high flowed stockies?

Hi people, im looking at side feed injectors for my RB25DET. Are genuine JECS 550cc injectors any good? I understand that alot of higher cc JECS injectors are in fact high-flowed stock ones but its the genuine brand new ones im talking about here... cheers Justin

you are going to need to give alot more information than this for people to help you. Tho based on the fact you cant ascertain if it has a clutch/ thermo fan then id say you need to be taking this to a mechanic. N going on your post statement "fear... is a great motivatior"- here it is for you. Overheating a car = a rebuild. If yours is doing this n getting that boiling sound then you are either very close or already there. Get it to a mechanic (on the back of a tow truck would be my recommendation...)

I also agree. iv got the 8/6 BC's and they are awesome. Had 9/10 before Tein/HKS (drift suspension) and it was nightmare stiff- ultra enjoyable for the few chances you get to use it for its intended purpose. But again, all depends on your driving style. If you never get really stuck into corners, do mad breaking, and especially throw the odd drifty powerslide then maybe softer is an option. But if you do, then 8/6 is a magic number in my book (and many people's), especially if it is adjustable- also makes a big difference in being able to make it behave how you want it to -not sure where in Aus u are but if you are in Perth let me know. ill take you for a spin.

exactly. people will drive it if it fulfills thier requirements. If you f*k it up and end up not appealing to your customers then they wont buy it. Ill drive a 50cc 1 cyclinder if it has 300 at the ground and delivers it like my skyline does now. As will most people drive a car with whatever motor if it does the job they ask of it.

a tonne is better than the roughly 1400kg we weigh that motor down with again- fine work

awwww yeah. Well done boys. how much does that thing weigh?

I like the way you think Simpletool. sounds like that something that can be gotten wrong tho- hence the multitude of comments about the MX5 turbo a few years back that "it feels like the turbo isnt hooked up" its a shame when they go too soft... Iv driven one myself and was thoroughly dissapointed. With a turbo you really want some sort of power curve/top end push to let you know its there. Certainly didnt have that...

yep.

had a similar problem myself. It was the stock rubber intake pipe distorting/sucking shut. my symptoms led me to find this out as it was doing it more when the conditions were warmer (therefor rubber is softer and more able to be sucked n distorted). I put in a metal intake pipe n that sorted it perfectly. if you are only every going to go for about this power (famous last words) then one of the cheaper silicone intake pipes may suffice but otherwise i highly reccomend a metal one. It also means more power is possible in the top end due to the better air flow. I went from 290rwhp @14psi(when the intake wasnt sucking shut) to 300rwhp @14.5psi (the intake allowed for a bit more boost) just by replacing the intake.

1-not exactly. but what it has done is develop technology that enables engines to rev higher, and more reliably. 2- yes and no. But it sounds like you are coming from the perspective of increasing power aftermarket. Building a car in the manufacturing process to develop 'x' power (x being quite a high figure- lets say in excess of 500-600hp) then building a turbo motor to do it would arguably be cheaper. Again, still something very debatable. But i spose a good point to consider is how many road going manufactured cars in excess of 500hp are turbo'd n how many are NA.. 3- true 4- true 5-also true. Cmon, we have been dying for larger cc skylines for ages. Hence RB30/25

yeah, i want me one of these. Porsche variable vane turbo's -dont mind the pole smoker voice over. the sweet spot is at 0.52 "620nm of torque from1950- 5000rpm".
