You can still control timing without stuffing around with the cam to make a motor safe, I have no idea why you would do that.

The second guy sounds more like he is suggesting retarding the intake cam to increase torque in the lower rev ranges with the expense of top end, that in itself might be a good idea depending on what you want but you can still do that an have the motor unsafe (too much timing, too lean, on the knife edge of detonation, too hot etc)

Basically, trust your tuner, hes probably done a lot more cars for a lot longer then keyboard tuners on here

haha, the previous quote just aletred me to this comment. So how many have you built? Clearly the one GTR you owned that you probably paid a workshop to build for you makes you an expert does it lol

Please correct me if i am wrong though as i like being proven wrong.

You and I both know that if the thing blows up tomorrow, that your in a pretty good financial position to get it fixed anyhow thumbsup.gif

What a shit attitude to have, you can afford to fix it so lets go and f**k it up. Not your exact words but thats what your implying. With an attitude like that you dont deserve to own a GTR in my eyes

Should my mate go out and crash his Superleggera or blow the motor up just because he can afford to fix it. Hell no. Why someone would want to damage something just because they can afford to fix it is beyond me.

Are you really that f**kin stupid...?

Don't believe I was saying that he is filthy rich and should blow his car up for the sake of it!

I was implying that working in a coal mine and receiving $150,000 a year plus Superannuation puts livewire in a better position to fix his car "if" anything goes wrong with it.

Unlike someone who maybe massively in debt just so that cam be a cool flamin mongrel with a GTR...

Keep ya dumb ass comments to yaself. Ya dumb ass.

I gave Jim A call this morning as he said to give him a call with feedback after driving it home and if I had any issues etc. I questioned him about the boost level and he said 1.15 bar is no issue at all and he has tuned between 70 and 80 R34 gtrs over the years without any issues so I think its fair to say he knows what he's doing. As for the dyno reading, Jim said his mainline dyno has twin retarders which is where the readout is lower than the actual power being made and he confirmed the car is making about 280kw. If he was going to bullshit I'd think things would be the other way round putting higher figures on paper to make it look good. At the end of the day I'm 100% happy and confident in the work done. The car has a lot more response, torque, better fuel economy and the car starts first turn of the key which it had troubles with before and for the price I was charged for fitting of the injectors, power fc, tune, oil change and filter, new spark plugs I couldn't ask for more.

He may have said GTR's in general but made it quite clear he has seen a lot of R34's running stock turbos at this level with no issues. As someone earlier in the thread said... he's been running 1.2 bar for 6/7 years with no issues. If something happens, it happens. You don't play with cars and modify them if you don't realise there's risk. I'm happy with it in more than just the power increase. It's a better car now in general.

I haven't ignored any advice, hence calling and asking the tuner himself about the issues people have brought up on here which I am greatful for. But the tuners advice is the advice I will be taking as he knows the car better than anyone on here, has seen, tuned and worked on more cars than anyone who's commented on here as he does it for a living and has been for years. I could have ignored any advice but didn't. I called to double check and he has reassured me.

There doesnt need to be a risk though.... if your building a race car and want everything out of it then yes, you will run it closer to the edge,but even then there should be no real risk of hurting the drive line.

If you need to risk something to get somewhere/something or achieve your goals, then it hasnt been built properly or your simply asking to much from it.

I built an engine for my car and my intention was to have the car as a streeter/weekend drag racer. I wanted abot 700hp and that was achieved 5+ years ago.. I didnt build an engine with stock rods and pistons because i have seen them hold this power level before, its a risk they wont, so i built it accordingly. I have seen stock motors with huge ass turbo's making 700hp but for how long....

Clearly, as your mate has pointed out, you have the cash flow to build it properly so why would you take the risk in hurting more than just a turbo charger. Its well documented that some turbo are luckier than others, but that also carries through to the engine when the turbo fails. The engine will probably go for another 10 years if its looked after. Get some -5's and swap them over and it will make 300+ with the support mods you alreayd have. It will do that day in day out and you will never have to worry about a turbo failure due to a wheel falling off.

You may have one of those lucky pairs of turbos that just dont let go, but you might also not and i assure you that you will kick yourself if one of them lets go and it takes your engine with it

has seen, tuned and worked on more cars than anyone who's commented on here as he does it for a living and has been for years.

Are you sure about that lol There isnt only one GTR mechanic in Sydney mate, lots of us on here have done it for a living

After reading all three pages I have one question;

I was implying that working in a coal mine and receiving $150,000 a year plus Superannuation puts livewire in a better position to fix his car "if" anything goes wrong with it.

Where does when get one of these coal mining jobs!! :)

Lots of stories about blown turbos = blown motors. I keep my 32 to 1 bar (should probably even be lower).

Better yet just go the -9 route if you can.

get an engineering degree and some experience, or become a sparky and work in one, I'm sure you could get there after a couple of years.

Or leave high-school in year 10 and wing it and oneday ya end up driving 400ton mining trucks and 1200ton diggers. With no brain and therefore no qualifications!

hehe ye, just drive a truck and you'll be close without any paperwork at all!

2 years

drive truck

PROFIT?

I questioned him about the boost level asnd he aid 1.15 bar is no issue ... he has tuned between 70 and 80 R34 gtrs over the years

He may have said GTR's in general but made it quite clear he has seen a lot of R34's running stock turbos at this level with no issues.

Well "in general" or "70-80"? Chinese whispers again!

Or leave high-school in year 10 and wing it and oneday ya end up driving 400ton mining trucks and 1200ton diggers. With no brain and therefore no qualifications!

yeah f**k driving trucks though, would be extremely boring and unsatisfying.

Ohhh dear. I think this will be the last time I post anything about performance etc on here or try to give someone's work a wrap. I'm The first to admit I don't know everything about the car therefore ask questions and leave it in the hands of the people who do. I simply thought I'd share my experience and thoughts of the work Dart performed and I'm happy as I'm sure many others are too including the guys at just jap who use Dart for they're cars and recommend them to they're customers which I think is a clear sign of confidence in them. Yes, maybe there are more people on here that work on/tune cars for a living which may explain why a lot of people like to question the work of others/bag them out. Some of yous may find it amusing to read etc and I'm glad I could provide you some entertainment and thanks for the input. And as for having a good income... yes we do get paid well for what we do but the more you earn the more you spend, trust me lol. I live week by week at the moment! Haha.

    • I'm looking for some real world experiences/feed back from anyone who has personally ran a EFR7670 with a 1.05 exhaust housing or a .83 I'm leaning towards the .83 because its a street car used mostly for spirited driving in the canyons roads. I"m not looking for big numbers on paper. I want a responsive powerband that will be very linear to 8000 rpm. I dont mind if power remains somewhat flat but dont want power to drop off on top. The turbo I've purchased is a 1.05, although the mounting flange T3 vs T4 and internal vs external waste gates are different on both housings, I not concern about swapping parts or making fabrication mods to get what I want. Based on some of the research I've done with chat gpt, the 1.05 housing seems to be the way to go with slightly more lag and future proofing for more mods but recommends .83 for best response/street car setup. AI doesn't have the same emotions as real people driving a GTR so I think you guys will be able to give me better feed back 😀   
    • Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?
    • This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?
    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
