Hey all,

I seem to have a problem with my S2 33 GTS-T. The Bosch 040 in tank suddenly has gotten REALLLLLLLLLLY loud. It's never been this loud before and only seems to be getting louder. Previously to getting it tuned (3 weeks ago), you couldn't hear it at all. It got tuned with new injectors and I'm assuming the PowerFC is asking it to flow more so it's louder. Loud being the whiney noise you hear when it works.

The car cannot boost at the moment. It was fine after the tune, however I took a drive up to Newcastle and on the way back it started spluttering when I boosted it. At first I thought it was the clutch slipping so thats been changed for a new item. Now it's still doing it. Basically on stock boost or any boost, the car runs fine but when it tries to boost at 4-4.5K rpm it starts to backfire, and the engine cuts in and out. The same feeling you get when you hit redline except it sounds like it's backfiring. Doesn't matter what gear it is, as soon as it starts to boost same thing happens.

Does anyone have any ideas or questions which might enable me to sort it out? The only thing I can think of is the fuel pump? It was boosting fine after the tune. Two days after the tune I took it to Newcastle. It's since been off the road due to me waiting for the clutch and installation and now it seems the problem is still there.

Any points would be greatful. I'll be taking it to a workshop soon but just interested to see if anyone has anything to add :P I only drive it back and forth from the station but I'm worried more driving could potentially cause damage to it.

Thanks all for reading :no:

Probably the classic dying coil packs.

They all do it.... in fact mine is doing it at the moment too. You'll most likely need to go get yourself a replacement set of coils - unless it turns out to be something else that's causing the problem

Same problem struck me; my 040 got REAL loud and then I started to lose power a week or so later. Turned out the pump was rooted and the power loss is due to the pump not maintaining adequate fuel pressure. Changed my pump and all was sweet. On a side note, my 040 was less than a year old and was in really bad condition when I removed it from the tank so I am now a little dubious of bosch's quality control.

i've heard quite a few horror stories about the bosch fuel pumps, but then i'm sure heaps of people have no troubles with em. I wouldn't get one though.

Gus have you by any chance tried hitting it with a hammer?? That works for me with things....

      Hypergear ATR45 SAT Turbo With addons (brand new - never used)

      By Danowner · Posted

      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!

      Hypergear ATR45 SAT Turbo With addons (brand new - never used)

      By Danowner · Posted

      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!
