Got my turbo installed today by my mechanic (Barry from Performance Jap specialists). JPC turbocharging built a high flowed unit for me, Sierra s3 exhaust wheel with t4 front wheel and machined housings. Also a plain bearing core.

Got it installed today with a new Walbro 255 l/h fuel pump. The old turbo had suffered bearing damage and the wheels were doing some machining of there own ;).

After driving it I was completely amazed. No big suction noises coming from turbo, just a clean soft whistle and there was a fair bit of lag. You drive along and when it hits about 3700 rpm all hell breaks loose and its like its been kicked. In 3rd, it breaks traction so violently on the run, its scary. Im getting used to it and I dont really mind it, it reminds me of driving my old school starion that had lag then the kick! My last 3 cars have had ballbearing turbos so I forgot what lag was all about.

After 3700 rpm it pulls like a train and in a blink of an eye its past the redline.

Managed to go to Rajab dyno day and get a reading, pulled 208 rwkw on 12 psi. Was incredibly happy with this, I dont want to go overboard on boost since im running only a remapped management. Im also only running a STOCK DUMP PIPE!!

Im completely happy and satisfied with how the thing performs now, its totaly different and much quicker. Looking forward to gettin the Link installed n tuned along with injectors.Got a mental split dump with screamer but the flange was different and I didnt want to hack up my Nismo Downpipe, so Im getting a custom one fabricated.

Congrats on the upgrade, good to hear you are happy ;)

But i have to agree with INASNT; till you prove me wrong and take me for a spin ;).

I have 235rwkw and i never break traction in 3rd, on the run. 2nd is a different story, just ask Shivam, Adz and Pete ;)

I have Dunlop SP8000es 265s on 10 inch Advans.

They did 2 sec flat 60" ft at heathcote. As I said it is a fair bit laggy so when it hits it hits hard.

The suspension is currently standard due to me waiting on a NEW set of coilovers.

My freinds 33 has a powerFC and exhaust, dump, cooler usual shit stock turbo and made 209 rwkw. You cant judge how fast a car is just by a reading of its peak power.

Last nite I left him by 8 carlenghts, on numerous occasions. Dont wanna start a war with you people Im Not a dyno queen, theres other ppl out there with a lot more power than you. I enjoy using my car for drags, but mostly drifting - Ive seen people out there that have a lot of power and cant drive there cars for shit.

Im very pleased with the minimal outlay of $$$ ive spent on getting my turbo and fuel upgrade.

Thanks guys!

I got the turbo for a real good price, JPC is one of my customers so he looked after me. I watched it being assembled as well. If anyones interested in a turbo from them, let me know.

As far as management, Im still thinking, Ive seen a few skylines with links that are producing decent power, I would love a PFC, but when it comes down to it, the PFC isnt that much cheaper in the end. Im content with it now!

Went on a cruise with it today, my uncle in his 993 Porsche 911 turbo and mine, we had a awesome cruise up to Gembrook, on some nice twistys, the car was feeling solid and the turbo came on nice and strong. I love the twisty stuff!

I will get a pic of it during the week to put up.

Also to note, this figure was achieved with a stock dump pipe and a stock R33 Cat.

Those upgrades should yield a healthy power increase. When computer and injectors are on it will be even more interesting.

on the graph it goes up smoothly then hits with a power jump and keeps rising.

    • Was planning on getting an R35 MAF and the adapter, should this be okay? Also any idea where I could get my hands on an intake pipe?
    • I mean yes, if you're starting from scratch on an unknown engine yes you don't need to be doing all kinds of math in the background but if you're doing relatively minor changes like AFM + injectors + boost up with some aftermarket turbos it takes quite a bit of math if you want to do something like maintain OEM fuel + timing tables but compressed and then a bit more load scale up top. I think I've spent too much time working on big engineering nightmares though so I'm a big fan of trying to constrain the scope of whatever work I'm doing as much as possible and trying to get it right before moving on. For example, a local owner just did the usual E85 + single turbo conversion to his R32 GTR and nearly burned his car to the ground doing some spirited driving up the local mountains. Turbine is unshielded and too close to the hood insulation. It's tough to balance "just get the project done" and "seemingly small details can cause massive setbacks I'm not willing to deal with".
    • No idea about Neil's steering wheel, but I have the same behaviour in the Stagea. I doubt it has ever been messed with so might be normal. Indicating to turn right at a roundabout and correcting even a little bit to the left to go around will cancel the indicator. Never considered it an issue other than it being a bit odd.
    • Does anyone know if this is off centered? Looks like it, when I indicate to go right, but turn my steering wheel slightly left it cancels (was always like that even before I started messing around with it) was wondering if anyone else has the same issue?
    • Nothing photo worthy since last update, lots of little plumbing bits for the AAC/Cold start valves, and unfortunately I still need another couple of parts for the brake booster line and the AAC into the plenum. Otherwise it all looks good to start up engine wise, onto checking the electrics/interior
