Hi guys,

Just after some help for my r34 gtr..

It was fine last time I drove it and has been parked in my shed for the past 3.5 months while I have been working away. Today is the first time I have driven it since and it started all fine, drove it for over an hour all good, washed it at the car wash and as I was parking it up to shammy it dry it was hunting up and down almost to stall from 950rpm-609rpm (power Fc). I have since driven it home and all was fine when driving, only at idle it does it.

I put the a/c on the problem goes away and I turned the a/c back off and the problem was fixed for awhile i turned the car back on and the problem was there again.. so I decided to clean my z32 Afm's and no difference in the idle.

Could it be stale fuel causing this problem?

I don't think it's the afm's ..

Hi Choyda,

It's only a brand new fuel Walbro 255l pump installed by my tuner 5 months ago

I hope it's not the pump.. But then again it has been sitting for a while..

Not really running overly rich I would just say normal

With a PFC there's often a problem with the hot start and not with the cold start.

It tends to happen when the car has been standing for at least half an hour to a couple of hours after a run. It can take a few seconds after hot starting for the PFC to catch on.

Your tuner might just adjust the idle for you within the narrow boundaries of what a PFC will permit.

Hope this helps.

      Yeah pretty impressive hey, good to see quality products not over-shooting their prices. That's what drew me to buy the hypergear turbo, just a shame I've never got the chance to see it in action

      Thank you GTSBoy and MBS206 I have done the compression test with the motor out of the vehicle, reason for the test was to see if I needed to remove the head and do rings etc while its out. I'm in the process of respraying the vehicle and tidying up a few things. Story behind it all is I've just purchased the skyline and it was running when I got it, never drove it on the street though as I wanted to pull it down and do it all up again before registering it. the gentleman I purchased it from told me the motor has a forged bottom end and has a decent tune through it but I was going to pull the sump off anyway to see if it is a forged bottom end. that's why I thought id do a compression test beforehand.

      Man, I'm kind of amazed that the price of the turbo has not changed in 7 years. Everything else is inflating beyond reason, but not this? Good on Tao / hypergear I guess? Anyways, good luck with the sale!

      I'm selling my brand new, in the box, never used Hypergear ATR45 - and I had some additions I paid for a few yrs back when I purchased it. Never ended up having the rest of the money to add all the mods at once, so I just ended up slowly selling each part. I originally had it internally gated, with the dump pipe, however I found it was incompatible with what I was going to use it for, so I contacted (I think Ken) from Hypergear, and he and I messaged back and forth & he got me to ship the turbo back, where they modified it & made it externally gated, and gave me the 5 bolt dump pipe attachment for custom welding. (Photos below) This turbo like I said has never touched the inside of an engine bay, it's completely brand new, never used, been sitting in the same box it arrived in, covered in plastic & all. Below are the photos of it: And while the guys at Hypergear were making it in-shop, they sent me some photos of the process: I'm looking at selling this just because I'm in need of the money right now, and don't have plans on modifying the 34 anytime soon - and from reviews & peformance sheets, this turbo had amazing results back when I was researching. The turbo was purchased in 2018 for $1.9k, with the mods I got added on. Looking at the website now, for the same turbo they sell (ATR45SAT), with the current addons it adds up to $1830 for the turbo Current addons included: - Bolted dump adaptor - Ball bearing CHRA - Braided oil feeding line So I'm looking to possibly sell it for around $1800, with shipping included in that 1.8k, It cost me around $120 to ship - so yeah thought I'd throw it out there and see if anyone was interested in purchasing. Cheers!
