I cant believe no one has suggested the boost solenoid hack yet!

The ECU makes the car run less boost below 4.5k then it runs full boost after. There is a tutorial on here showing you which wire to ground so that it runs full boost at all RPMs, will give you a much bigger punch in the midrange.

Definitely give that a shot!

Have a look through the power thread mate if you want to make a set power level. If you put on even a catback and up your boost to say 12psi (safe limit for the turbo) you'll be on 160-185rwkw in an r34 gtt (depending on a bunch of stuff), so I'd imagine an r33 gtst won't be far off it.

D13 = 140rwkw (STOCK ECR33)

D14 = 9psi

171.1=D13*(D14+2)/D14

i think if the ECU was tuned properly and suitable exhaust, intercooler, intake etc

but with bog stock everything adding 2psi i dont think will give you those gains above

Is it meant to be absolute pressure mate?

I was just going to quote you here haha:

HR32 - A = 0.8 and B = 0.9 kgcm2 which is 0.85kgcm2 (average) which is 12.08 psi

BNR32 A = 0.7 and B = 0.8kgmc2 which is 0.75kgcm2 (average) which is 10.66 psi

ECR33 manual is 385mmhg which is 7.4446 psi

ECR33 auto is 270mmhg which is 5.220 psi

BCNR33 A = 0.79kgcm2 and B = 0.85kgc2m which is 0.82kgcm2 (average) which is 11.6 psi

be sure to note, that ECR33 has dual stage boost, that is the std solenoid will bleed an additional 2psi above 4500rpm

so if the std actuator according to the nissan spec manual is 5psi for AUTO R33 GTST, then at 4500rpm+ to redline, you get 7psi minimum boost

so if the std actuator according to the nissan spec manual is 5psi for MANUAL R33 GTST, then at 4500rpm+ to redline, you get 9psi minimum boost

I'm pulling 182.7RWKW from my manual R34 GT-T with just a 3" turbo-exhaust + Blitz FMIC (peaking at around 8.5psi, dropped off to 6psi by peak power) on what I've been told is a fairly conservative dyno - with a factory tune ... yeah - I was surprised too :geek:

jrm 182rwkw is about what i would expect from a car with you mods on an R34. I think willalls dyno was reading fairly true on that dyno day. my car made 327rwkw which is about what i would expect from the boost level i was running (only 20psi). People are just use to running on "happy" dynos...

That's high for such low boost, it seems ppl in the dyno thread need much higher boost to make that... I'm gonne get me a turbo back, this cat back is annoying lol.

What 3" system did you get?

The GReddy/Trust PE II on mine is nice and quiet for a cannon :D

I don't know what one I got to be honest... all I know is it works awesome. It sounds mean too! really raw compared to the four inch tip I had. I think I will put a resonator in still just to quieten it down a bit. It inly has a single muffler at the moment.

I think I will wait for a fuel pump before I install my boost T. Once those two are installed I might go for a dyno run.

    • So could it be assumed it has been installed intentionally with potentially a power FC boost controller kit? 
    • Had my rig on Matt's dyno at PITS the other day. After a few years between tunes I added a few sensors and swapped intercoolers. Result. 553hp at 26psi. Not bad for an FJ20 that was built in 2007. The problem.. It filled the overflow bottle on hard runs which leads me to believe the head gasket isn't sealing. I have a coolant pressure sensor which was reading cap pressure at 22psi and occasionally overrunning to 23/24 psi on deceleration after a pull. It was not spiking. It has arp2000 head studs and a cometic gasket. As its been 18 years in service, I pulled the engine out and head off. Everything looks good but we obviously have an issue. Where I'm at.. Years ago I had the same issue, I checked the stud tension and they were all over the place. Some at 60 to 70 and some up near 90. I nipped them all to 100ft lbs and this stopped the water push until now. I believe this compromised the gasket back then. What do I do? 2 options are..  1) I bought arp 625+s, which I could put in with a new gasket. Thinking Kameari this time, reassemble and try again. 2) strip the block, get fire rings machined in with copper gasket and try that. I do not want to push it more than 28 to 30psi. I think the turbo will be out by then anyway. (G30-770). My other concern is the long term ability of a copper head gasket. Are they streetable for years? I feel like a new gasket with the new studs will probably suffice, but I don't know. Any thoughts welcome and advice on copper gaskets and fire rings. Thanks!
    • I'm a fan of the JZX110, and the Aristo. Big cruiser cars, and with the factory cars, super comfortable and feel like you're driving an armchair! And the JZ motors are a pretty nice engine too, especially with some basic mods.   The import process, and the need to be able to trust people, and the fact there's so many scammers around is what ever puts me off wanting to go through that ordeal!
    • I don't care for these at all, but at least the underside looks straight and not rusty. A good basis for a long life. Many cars from Japan have been lifted with forklifts and f**ked almost irrepairably.
    • Yes, but it's not dumb or dodgy. You can build a perfectly good boost controller from a pressure reg, a relief valve (looks same same as a reg if all from Norgren or SMC, for example) and a check valve. I ran one for years. Only superceded with  EBC because I could get one for cheaps and wanted finer control.   THis mod is certainly not a sketchy boost mod, provided the boost is kept below the "spin to death" threshold of the turbos.
