The sound gets better with more power/exhaust flow so all those things affecting flow contribute. So depending what you choose like Capacity, compression ratio, camshafts, exhaust mani, turbo size, exhaust size, external gate and muffler choice, the tune and power levels make the sound. At that level experiment with kakimoto or hks or some aussie combo, the problem i found was that at low engine speed the drone is annoying with big pipes so i made a helmholtz resonator pipe which quitens drone on cruise.. each to there own but works and sounds sweet for me...

Cant beleive this happened but was bit dark and i wasnt paying enough attention. I put the jumper leads on wrong and big spark and bit of smoke off the negative terminal. So now it cranks and wont fire up. Has anyone done this before and what could be blown?

Thread revival.. I'm thinking of getting RB25 Tomei pistons and fitting to some forged RB30 Rods in the RB30 block. I prefer tomei pistons as the piston clearance is tighter and Jap is better. My last experience was i fitted cast oem 25 r33 pistons to RB30 rods with r33 head and contradictory to what people beleive, the comp was high not low.. comp test showed 200psi Although the 25piston sat lower it has more meat ontop so actually was fine, correct me if im wrong. Now with a neo head im guessing comp maybe too high but its using E85 anyway and the tomei 260 cams lowers comp at low revs and comp test anyway so would 10.5-11 :1 ( guessing) comp be ok with a 3076 and E85??? Or maybe a thick head gasket will help out too... The cars still going strong, just preparing as cylinder 6 is slowly going down..

Yes running out of fuel, the pump wiring was upgraded as he said it wasn't getting the full volts, so sounds about right then.

That's weird then, last time it was tuned it was maxing out the 400lph walbro with 1000cc injectors on E85, is that about right or was the stock reg leaking maybe...

Aeromotive 13129, rated 1200hp.. No wideband, tuner plumbed his own guage in the line and showed me the pressure changing, I'm not sure exactly what i was looking at now. I guess I'll just put her back on dyno then.

It's a black Aeromotive FPR from efisolutions , I replaced it cause the old tuner said the fuel system was all clogged up from E85. The old reg is over 20yr old so thought is a good improvement, I set the pressure to 44psi but tuner says its raising the pressure with boost alot different to a stock reg so the fuel map needs retuned. Before we could tune it, a Welsh plug backed out from the back of the head right next to the fire wall. So just wondering if it really needs a tune still cause i cant smell much fuel if its apparently rich and no knock showing on power fc either.

My RB3025 making 345kw had E85 fuel issues with dirty injectors so I cleaned them and changed the reg to a rising rate one. The tune was done with a stock reg so I'd like to ask will the rising rate reg mean the tune be off? Like will it now be much richer on boost and need just a tidy up or a full retune?

$100 each

$150 each.. good for a built motor while still driving the old one..

SOLD.....☺️

So he should get a Tomei or Nitto head gasket?

I know my RB3025 has no issues at 350kw, is a simple oem RB26 gasket that was very reasonable cost from Kudos with ARP studs.. If the block surface isnt perfect then it could leak and after pulling engines out a few times recently im over that bullshit so id advice OP to keep it simple.

Just get a stock RB25 head gasket and ARP studs..

Both are stock bore and had good comp,have oil pump and crank, bores look good, pistons removed from one block. Block 1 - has 5 pistons $250 Block 2- bare block $200 Jimboomba 0466257118

Forget to mention, its Mod plated and legal for the RB30, intercooler and susupension.

Stagea rs4 s1 for sale I've done a fair bit of work on this car so its got potential for someone to take it further. -RB3025 I took a good running RB30 and RB25 and put them together, new belt, tensioners, has VCT, stock head bolts, stock RB26 head gasket, RB30 sump, i used RB25 pistons and rings bolted onto RB30 rods and bearings.. all clearances were measured and within factory specs. Motor has 200psi accross all 6, no blow by or weird noises. - stock turbo in great condition and ecu etc stock - fmic - adjustable camber arms all around - 3inch exhaust turbo back - 370z wheels, new tires on front - air con is ice cold - Big alloy radiator Bad points - auto slips in 4th - suspension is bouncy needs replaced - starter motor bit noisy but still works every time. - previous owner put some gay lights in the cluster So has potential but its not perfect hence a low price, advertised elsewhere and can pass a rwc for the right price, has 5months rego atm. Located Jimboomba $3800 with rwc $3500 as is Pm for mobile 20191020_175305_1.mp4

Sweet, thanks mate, i'll drop in for a chat

They sound like a good shop, i dont wanna deal with shops that dont know what they are looking at. I'll give them a ring, cheers

Drove her over the weekend and today to work, well theres alot of things to fix to make her sweet but oh well atleast it drives. I've found that 4th will flare under load so the auto box is dying unfortunately. But im gonna rock it til she dies and im looking into my options. On the bright side i freaking love it, 1st and second haul ass in traffic, the stock turbo spools rediculously loud and is very entertaining, many laughs had for sure. The thing idles so innocently but sounds like a jet, pulls well upto 3.5k then shows over haha but still fun.

I like the z32 idea though as would be strong and cheap

Ahh well thats not too far but labour adds up unless i just tow it once ive installed it, z32 autos are pretty old now though

I already have a manual in my r33, this car i want to be auto to be different and with manuals unless i pay $3k from japan for a new box it might turn out to have worn synchros/crunching etc anyway.. If i remove and install myself then maybe will get away with $2kish??

Does it bolt straight up and work?

Can i use an R34GTT 2wd autobox?
