i'm not going to be able to afford big cams, but i will get a good exhaust manifold then, a hi mount, what about hype33, he gets 305rwkw on 15psi with no cams, do you think thats just a happy dyno, do you know how much i would be looking at approximately with around 1 bar and decent hi mount manifold, i already have a 3.5 inch hks straight through exhaust so i think it is breathing easy

i just wanna highjack this thread quickly as i am having the same dramas with choice of turbo for my engine

Im not sure whether to go GT3082R or GT3582R.

I have stock internals aswell, with all supporting mods, including poncams.

i will only be running low boost as i dont wanna pop the engine, but i would still like to make ~300rwkw

they hard part is peoples different perception of how much lag is too much, i want something thats quick, 4k is fine to wait for it, but

this is in an S13 so im not sure whether it would be suitable as its probly just gonna break traction as soon as it hits boost. Now as fun

as that is for around 3weeks, it gets boring after a while hehe. i would like some response but i dont wanna hafta run high boost on the

GT30R to get it.

EDIT: lawl first post finally after over 2years :)

Simply bolting a turbo on 2 different turbos on to an rb30det with stock inlet, stock cams, stock exhaust manifold.

One had a GT35r .82 bolted on to it; nothing was port matched. 17psi 270rwkw

My own had a Gt30 .82 bolted on to it; I port matched everything + it did have a little port/polish. 15.5psi 268rwkw

Turbo size at this power level I don't believe has much if anything to do with power vs boost.

Get the motor breathing better is the best thing you can do.

    • Reasonably hard, although I haven't run it with the new Endless setup yet. The old brakes were F50's on 335mm rotors and the car did a 1:40.6 at Phillip Island which is a reasonable time, I'm seeing high 600s on the temperature paint. A guy I know ran the Endless fluid at WTAC without issues and he was doing 1:33's I think (Evo) with a 355/332 setup. I don't get out to the track as much as I'd like but we put the car on the hoist and spanner check every bolt and re-paint mark everything, bleed the brakes, change the fuel, check the coolant system and re-bleed blah blah blah before every event. Motorsport is expensive, RB's are expensive so a couple of hours before an event is time well spent. It's also a net time saving because if you can keep your RB from self destructing it saves you time in the long term!
    • Welcome Alice......hope you have a bit more luck from here on! What was done in the build?  
    • Hello! I'm new here, I have an R33 GTST that is currently being finished up! Last year was pretty rough, blew two stock turbos so I decided to build the car. Has been down since November, but I get it back next weekend!
    • Hello, I believe my car was imported to America in the 2000s by Kaizo Industries. Would anyone be able to help me find more info on them? I've only found all the basic stuff like that paul walker bnr34, them being shutdown by feds, just stuff like that. Any help would be much appreciated, thanks!
    • I am using Motec M150.  I am not working on the car myself actually.  My workshop is giving all these info, they are quite reputable in the industry and are very familiar with Motec and RBs and have done a few big setups with VCam and single turbo on RBs.  In fact, they built and tuned my engine from day one.  But they are stumped with my engine at the moment and cannot work out how come the compression is so low with the VCam. They told me that they have now swapped in some Kelford cams (without the VCam) and can achieve around 130psi compression and the low end torque is better, but now the engine is doughy as.  It boosts and peaks at more than 1000rpm slower, with twin HKS GTIII RS, it doesn't get full boost until over 5000rpm. I have always thought the VCam was a bit disappointing at the low rpm. To a point I had to ride the clutch a fair bit to get up a small hill from stand still.  That was when I had a clutch.  Now changing to a 8HP, I don't have that luxury and this problem has become a major issue. I am beginning to think the VCam never work since the day it was installed.  Maybe it was just sitting at the most advanced point, that is why it went good at top end but very ordinary at the bottom.  Therefore, with the help of the Holinger 6 speed and paddle shift, as long as it was moving, it drove pretty good.
