my rb26/30 with a gt35r 1.06 rear jun stage one cams, 1000cc injectors, twin fuel pumps, etc made 700bhp @ the fly and 660lbs torque@ the fly that was at 1.8 bar though, so yes its possible thats on 98ron pump fuel /uk we did a run upto 2.2 bar and got almost 750bhp/700lbs torque but turbo was overspinning. went to castle donnington race curcuit on friday , open pit lane and did 80 miles on track at 2 bar all day no prbs..bernie

i want as much low - mid toqrue as possible without excessive wheelspin. im runing the .82 rear on the 3540. how much boost could i run? a friend of mine on the standard rb25 (r33) ran 26psi which i havnt seen but ppl talk to much shit these days so just wanan confirm.

ive forged the bottom and aiming for the 500hp park.. so around 370 380RWKW.....

possible with standard cams? if not how big should i go? again it is a street car so trying not to get TOOOOOO MUCH attention with the lumpy noise.

p.s max output on standard pump fuel with standard cams?

no way in the world with std cams - poncams would suit you pretty well

was afraid of that...GOSH THIS PROJECT IS MAKN ME BROKE!!! lol

any idea wat i would crack out with standard cams?

looks like im gonna have to pour another 1.5k into cams and gears......any recommendations?

low-mid 300's with alot of boost

you are better off getting some headwork so you can make more power with less boost. as SK always says, boost is just a measure of restriction - the more boost you have to run, the greater the restriction in the system

cams and gears will be well under 1k. give dan from elite racing a call on 0407 111 229 - tell him shane sent you :P

what sorta headwork? and how much are we talkn $$$ wise.......far out this is not going well lol......

sorry guys wen it comes to engines im very new to it all.

i guess if i hit 350 i would be happy....

hrmmm sounds good, where abouts is dan located? QLD? because im in VIC

im picking the car up on thursday after a good 4 months so cant wait....but now im not sure if i should delay it for the cams now

yeh he's in qld. he can get the cams sent anywhere though

yeh he's in qld. he can get the cams sent anywhere though

yeh tru, although i always rather speak face to face.....lol

well ill keep u guys posted when i get my car back....honestly i dont know what the hell to expect......i hope the rb30 holds its reputation for delievering lol.

Have no intension on spending more money, so unless he is willing to do it for free, i have no need to speak to him :)

Spoke to two engine machinists and also an avionics engineer, that builds and repairs aircraft engines, all have stated that a pinhole in the block is almost impossible to see/find. A crack is different as it is bigger, etc., but a pin-hole would not show up on the x-rays or sonic tests.

Either way, i bought the block through my mechanic, so it is still being replaced, at no expense to me. But i will seriously consider buying the piston rings and passing the other info onto my mechanic, even though i am confident in his abilities.

Ok, I will bite..............why don't you just get the pin hole welded up in situ? Take no time at all on the hoist with a Mig.

The real question, how come it has a pin hole in the oil gallery anyway? Being oil filled, it's not gunna rust through like a water jacket.

My guess would be a crack emanating from the oil feed for the turbo or the oil return. That happens when people over tighten the fittings.

Sorry but after building over 40 RB30's, I just don't buy the random pin hole reasoning.

The repair of the hole has been lightly discussed over the phone, but i personally would feel more comfortable with the block replaced, especially for the fact that it is only going to cost me time and maybe a set of piston rings. As you have stated; i too am not convinced that a pin-hole would appear without a crack on the other side. Which still means that the machinest hadn't done his job properly, when crack testing the block.

Don't know how it happened, but i do know that it is not located near any fittings.

PS: Haven't seen my mechanic since Wednesday morning; has the sway bar been repaired and sent back? It had not arrived yet, by the time i left at 11am.

Were any pics taken of the problem?

Went 560 rwhp today on 23psi, and then started to lean out again.

Current setup is an 044 intank feeding a 044 in line - all on 98 BP fuel.

I think Ill have to go twin 044's and a surge tank to overcome this problem. Wanted to keep away from fuel pumps in the boot etc but cant see any other options now.

you could possible fit an aeromotive a1000 under the car

i was originally gonna fit mine under the car (32 gtr) but decided it would be easier to run it in the boot because of the fuel cell, and its a drag car now

    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
