Hey guys looking for some help picked up myself a clean r33 gtst s2 another a month ago my first turbo car and looking at some upgrades so please suggest away current upgrades

Return flow fmic

Fuel pump unsure of spec

Coil packs

Turbo back exhaust looks to be 3.5 force

Manual boost T

K&n air filter

Items I have purchased for the car yet to be installed

660cc side flow injectors

Apexi power fc

Z32 air flow metter

Bigger turbo 430hp rated standed replacement

Now is there anything else I might need before tuning ?

My 2nd problem if anyone can help

Me the turbo I've brought is a straight bolt

Up to factory manifold with some hot side piping adjustment but the standed r33 turbo waste gate actuator has a vac line running to it but the new turbo I've got the actuator just has a line running off to the side intake of the turbo so what do I do ? Please help thank you

Me being a new guy to this forum (learning as I go, a few parts behind you). Your parts list looks fine. Use the turbo upgrade thread to compare parts/power outputs etc.

Basic mods lists have been asked a thousand times on this forum, so just make sure you do your research although i do understand myself being a new guy it's good to have confirmation from others.

Injectors may be the only thing i'd take more of a look at depending on the PSI pressure you'll run. Additionally you'll want to know the spec of the fuel pump so you're aware of what it can/can't handle.

Also maybe replace the manual boost tee with an EBC for higher boost? Others may be able to clarify a bit more on that one.

As for the turbo Q, can't help as I have an R34 and so far that's as far as my knowledge goes! Best of luck.

Post a pic of the turbo? If there is no actuator on it, it may be externally waste-gated.

My only suggestion is to sell the PowerFC and have a Nistune installed, probably cost around the same but you will have the ability to run a flex sensor/E85 down the track.

I think he's asking more about how he hooks up the wastegate control signal. When I saw this thread several days ago I couldn't be bothered with trying to read through the mush of that last sentence.

Perhaps some clarification of the exact meaning of the OP is required.

Thanks for your help guys already yes it's a cheap China turbo how do I upload a photo ? Yes it's a just a internal gate with the acuator on the front the problem is the acuator has a line running off it back into the turbo so where do I hook up the vac line to? And with the fuel pressure on the add they say at stock fuel pressure you can support upto 600hp more than I'm wanting! And yes have already brought tein coilovers are stock gtst brakes bad ? Thanks

Run vacuum hose between the barb fitting on the turbo front cover and the actuator barb fitting. Just post a link to the turbo you actually bought....if its 430hp on there my money is on it being a t3/t4 thing.

No T piece required. Block off the original vacuum hose that fed the factory actuator. Plumb the piping exactly as the picture in your link shows.

As stated China turbos aren't the best. But they do still work to a certain extent....I wouldn't be pushing it upto 20+ psi as per the ebay specs though.

Do yourself a favour and get rid of that China Racing Development turbo, either flog it off to someone on Drift Sales or throw it into the bin...

that's the best advise I can honestly give you without being a total karnt.

So much THIS^^^^^^^

      Question about R34 GTT A/T Solenoids

      By DraftySquash · Posted

      So.... when I'm finally getting around to having my power steering leak sorted, now it looks like I've got the same issue most A/T Skylines are having. My A/T light will randomly come on and I'm stuck in 3rd gear until I turn the car off and on again. Only 3 weeks ago I did a complete transmission service: Oil flush + new gasket + new filter. This came out of nowhere!! It wasn't like the car was driven hard. I drove about 3 mins down the road to get fuel and boom!!!  Anyway, I have a few questions and hope you fine people can help me out here. All questions are in red. 1. The solenoids: I was looking at the parts catalogue in Amayama and I could only find the Solenoids as an assembly. https://www.amayama.com/en/part/nissan/319404ax05 I read in another thread that Solenoid A = 31940-4AX02 & Solenoid B = 31940-4AX05 but the Amayama product has only the code of B. Is this the right part? Can anyone who has done the Solenoid changes or seen them confirm if this is the complete set of A & B?   2. Gasket and Filter: I'm not going to try change the solenoids myself because it seems difficult to do in a home garage with just 2 jack stands. I plan to take it to a shop and get it changed. I was also going to buy the transmission sump gasket at the same time so I don't reuse the same gasket. Should I just use the existing gasket as it has only been on the car since OCT 19th? (~3 weeks) Should I be buying a brand-new gasket and a filter? Does this job involve taking the filter out?   Thanks in advance to everyone. It's hard to find a video of someone doing a solenoid change on a R34 so any help you can give answering my remaining questions would make me less stressed.

      R34 GTT RB rough idle problem with weird RPM gauge fluctuations

      By Kinkstaah · Posted

      Yea - From what I have seen from the video, the car idles like any R34 lol 50PSI of fuel pressure is hardly super abnormal, the regulator is working because the pressure remains static when the throttle gets revved, i.e pressure remains the same when manifold vaccuum changes. Bigger pumps on stock rails always bumped the pressure in the rail without using an aftermarket regulator to change that. Do you know what your IAC is actually doing? Has there been any data showing the stepper motor % etc? There's no way your idle is actually moving around the way the cluster(s) are indicating. You would hear the difference with the engine RPM flying to 3k and 1k in mere seconds. I'd be checking the wiring to the tacho. What the tacho is telling you and what the engine/ecu is telling you are different things. I assume your ECU doesn't display the spike. So whatever is telling the tacho to be at X rpm is doing something weird. When the going gets insane, you're on the wrong path. You've ruled out plenty of things that are working correctly/aren't the issue. Your idle isn't doing what the tacho is indicating. You have two seperate issues, I don't think they are linked, and the idle seems reasonably okay unless it's stalling which.. well, it hasn't. Troubleshoot the stall if it occurs by figuring out what your IAC is doing vs what it is being told to do.

      If it has had a code in the recent past, the code should still be there waiting to be read.
