75coupe

+2... bring on the CF with aerocatch locks

I guess the statement was in relation to the OPs want of a daily driver with no huge HP requirements and only wanting to rev to 5K rpm...? Heaps of people running arp by the sounds of it on here with alot more serous engine builds than this thread is sounding like...

one thing Ive never seen on this forum in regards to gtst is a bent butterfly...

Yep Ive got a turbotech controller so I'll chuck that in for the tuner as well...

yep thats what Im thinking since I heard he didnt adjust it, problem is now it will cost me another tune or atleast partial, damn I wish I could tune...

I can imagine it would be hard to be a tuner just like its hard to do any job but if I did something in my job that my client wasnt happy with they would ask why too wouldnt they... oh slap, hey I should of just added a smiley face it was a bit pun from other threads I read, I have no experience with hypergear and I think he does a great job... and I do appreciate your help, its more confirmation for me tbh Im obviously able to see there is a problem, I wouldnt say 'clearly need' though. so do you have anything constructive to add or are you just venting?

So bit of an update, Ive finally found time ot give the tuner a call... Basically he didnt touch preload from when Ive handed the car to him, apparantly he expected it to be setup properly, now Ive had it apart to do the HPC coat and also mod the wastegate bracket slightly so the rod is exactly straight coming out of the can, turns out the bracket on mine was different to the one that comes in the full kit. So not having preload even looked at is disappointing... He is saying it could be exhaust restriction, well I had the cat off and I could see daylight through the baffle/filter, so Im doubting that at this stage but if I can be stuffed taking the exhaust off and going for a drive I'll check it out, wait that actually sounds like lots of fun, I'll be a funny car for like 10mins... 'hollowing out the cat is the fix for that, its illegal now why not?' not my suggestion but I'll drop the exhaust and see what happens... or it could be the boost controller, doesnt sound like he has much confidence in the PFC boost control kit... I thought I had come up with a pretty good combination of stuff from my research... well I could easily be wrong... or the turbo has reached its limits, he was shocked when I said others have got 320rwkw on E85 from this turbo and 285rwkw on 98... so my instructions were to them to fix up the boost curve and we should find the power, doesnt sound like he will do it as part of the tune that should of been done in the first place, so it looks like Im doing the testing of exhaust & preload settings and then I'll report back my findings to them... surely any tuner would check preload... what does it come setup out of the box for them or something, No! so why not check it atleast.... hmmm I wonder if he will read this??? and yeah Im up for my money for sure... even though the injectors maxed out on me on a short squirt, 'well bigger injectors are needed', wtf... so I have the power of not even a HKS GTRS and the boost control of a hypergear... all out of a 2835 with HKS wastegate using all brand name JDM gear everywhere, how annoying...

yeah but is that genuine or just a copy???

really? I love that kit, but everytime Ive searched for it Ive only found a gtr version... link???

and its made only for the gtr.... bummer..

thanks for the offer but I work nights...

thanks man, now I guess it means the long trip to sydney this time to find another tuner and then the scary wait to hear the what the next huge bill will be...

the power curve did look a lumpy, I expected a fairly solid curve and boost control, like I didnt use any crappy or dodgy parts... I ask the tuner how it went he said it all fine, no problems everything worked together really well... These guys had a heap of other cars there, 33's, rx7s, VLs, a few dedicated drag cars and were really nice to deal with, this is not what I expected at all... oh well at least I can actually drive it to the next tuner this time I guess. now to find another tuner though and spend more money to get a good result, Im dreading having the next tuner reply by saying 'we need to remove this, replace this, redo this then tune from scratch'.... awesome. thanks for all the advice guys its reallt appreciated...

would I be right in thinking that preload & good boost control is a pretty basic thing that any tuner familiar with turbos (be it on any engine type) should be quite capable of diagnosing and correcting...? how emabarassing for them if this turns out to be the issue

ok I'll do that first opportunity thanks... and it will need to have the afr checked if that does change the boost control right?

here are some photos of the settings pages on the hand controller... They done make alot of sense to me, but the sensor chk looks like its highlighting sensor problems

I'll have to research to see how to check boost control duty cycle, but thanks all the suggestions are great...

well I did what I thought was right but I would of thought the tuner would atleast think it checking it surely?? I did tell them I did all the installs myself and did my best but they should atleast check what I have done... atleast Im hearing what I was concerned about that it could be better and that unfortunately it still needs some work at the tuners...

and of course that will mean adjusting the fuel map as well right? and that will I suppose cost me more right? and here I thought getting a tune from a reputable workshop would mean first time done right...

so new actuator to replace the HKS supplied one or does the pfc boost control just need some tweaking?

Yeah I was thinking that but they seemed really nice and helpful and they have a heap of experience... I gave them the task of installing the bov and letting them choose which one they wanted to use, the stock one or a atmo HKS, they chose the atmo bov but they did ask where I wanted it installed I said well as close to the thottle body as possible, so under the drivers guard is the only space really.. when I picked it up they said that they were really impressed with how everything was installed and that the bov positioning worked really well, 'Im going to set them up like that in the future as well... bit of a worry, but the idle is fairly good and none of the normal atmo bov issues...

if you dont care about kw's but want it better to drive just stick to the standard turbo and spend the money on handling, new bushes throughout, a good brake setup and good new tyres... it will drive great...

yeah really need photos... is it all carbon fibre or is it fibreglass with carbon fibre overlay?

thanks for the advice guys, I did think the boost control seemed a bit shaky... I'm running the std HKS actuator and the PowerFC boost control kit... I do have to go back for a bit of touch up on the tune so I'll see what they think but they felt the turbo was 'running out of puff' at 17psi so suggested the 12psi tune was the best compromise between power and not pushing the turbo too hard... I honestly expected 18psi as a start and go slightly up from there...

count me in too... Im loving your group buy ideas...
