Agreed, i think most of these 600x 300x 76 cheap intercoolers really are fine for 600hp. ive made 327rwkw with a stuffed r32 gtr cooler(looks like some kids ran their finger along all the fins)Realistically they are all basically similar, about 10 times bigger than the stock one so none of these would be too small.

mmmm cooked cat, sounds like a chinese take-away

The fuel in the fuel rail will only be flowing as fast as the engine is using it, so by the time the fuel travels to the last cylinder in the rail, it could have been in the rail for up to 1 minute if your going down a hill with minimal throttle, easily long enough for the engine heat to vaporise the fuel causing vapour lock and extremely lean running, and vastly different a/f ratios on different cylinders. Manufacturers do it the way they do for a reason, the fuel cools the rail. If your concerned about the fuel heating up, put a fuel cooler(oil cooler) on the return rail, but have an accident at your peril.

Just being picky, but 1:1 isnt rising rate, the risin rate malpassi's come in 1.7:1 and 2:1, hope this helps

Hi, i have a pair of 250/640R18 Dunlop full slicks with about 40% tread left. After $200 pickup hornsby, Sydney. Ideally suit 9in wide rim.

The power fc wasnt tuned for the increased boost before, as you weren't running that much boost, you will need to get the higher load points tuned for the new boost, shouldn't be expensive as it doesn't require a full tune.

Yes, this applies to the stock manifold, you are better off grinding the block, ,as it is only a small amount, and if you grind the manifold you will risk causing it to crack. P.S. im pretty sure an R34 manifold doesn't have to be modified, as it must be slightly different to an r33 one.

This could be due to the increased compression ratio of the n/a motor making the setup more efficient, hence more torque.

Hi, after a stuffed up deal with a supplier, ive ended up with two of these, and ive only got one car, im after $120 + post, it is brand new and comes with everything to fit it.

both cars assuming they are equal,, the one running more boost wil only make more power when its boost is higher than the other

one of my mates was running 19psi, and guess what he blew 3 in 6 months, the 3rd stuffed the motor.

Collers are $160 from proengines

and to run a jun pump, you will still need a collar

r32 rb20's havethe same problem, no power under 4000rpm if you fit gtr cams

Yep its ok for a low comp motor, test should be done with motor at operating temp with throttle open.

If its a series 5 itll be really laggy, even a series 4 will be very laggy, they aren't a to3 bolt pattern, and dont have very big compressor side to them, it would be quite a lot of work to make it fit, they are quite a unique turbo which is really only suited to rotaries without a fair amount of internal modification requuiring at least a to4 comp wheel, but by thr time you have done that, the budget isnt so attractive

Im under the impression that one turbo should be more efficient than two at the end of the day, as one 500hp turbo will not be twice as big internally as two 250hp turbo's. we did a gtr with everything standard except the hot side with a gt35R .63ex, made an easy 309rwkw at 16 psi, and comes on earlier than the stock setup, with cam timing and 19psi, 350rwkw should be in reach.

Quite likely a cracked oil pump, or the pump bolts have come loose.

After owning a z32 300zx tt, working on a gtr is almost fun

Although he did it to an rb26 to get around having to stuff around with sump adapters, which isn't a problem with an rb25

And they respond very well due to their torquey nature, its like an xr6t without the big horsepower potential. A few people on here seem to forget that a manual vr wagon is a good match for an r33.

Basically no, especially not using rb30 rods.

Then they should be good, still need to cc the package and figure out which head gasket you are going to use to determine your final comp. As for running the neo vct on an r33 computer, i dont see how it could work properly, as ive been told the neo has about 40deg inlet adjustment, wheras the 33 only has about 10, which is swiched, not variable. I guess you could fit a 33 camwheel and then it should work the same

Im assuming that these are the dome top pistons, if so you will end up with about 10:1, only ccing it will tell you though.

Obviously neo specific cams would be preferred, especially if you get poncams or such, however if you dont have a computer that can control it then the variable vct is wasted, especially if the cams are ground to siut the vct. Also a r32 and early r33's have a different drive to the cas on the front of the exhaust cam, so you need to see which drive you need for your cas. If you need to get rid of the vct, i would get an r32 gtr inlet cam, with a camwheel, as it is cheap, adjustable, and has fairly good lift and duration. On the exhaust i would run whichever cam you need to run your cas
