Andrew - Can u please ask ur 'tuner' from WA if he could possibly tune my car aswell while its at Ben's???? Willing to pay big dollar!!!! Oh sh!t, haven't got Tomei cams so looks like I'll have to wait for that extra 90 rwkws.....

By the way, i think you should change ur username to WOLFMAN!!!!

Yeah Jack without the cams, and without spending hours checking every possible timing combination then your really not committed to the cause.

But anyways.... the rain has stopped and I seem to be feeling a lot better today. Lets see if I can't make the shit stop.

:(

I saw your engine yesterday Jack - was looking good. But still had a long way to go. I should get my car back today which I can't wait for. Was speaking to Benno and it seem's you should have about 20rwkw's more than me so it will be fun to see exactly how much difference that makes. On the track the extra lag you have shouldn't be an issue I don't think?

Andrew - you'd be surprised at the amount of lag you'll have now aswell!!! Both turbos are pretty much on par with each other in regards to lag, around 5k rpm full boost.... Cams should bring full boost on a little earlier.....

Well I started a thread last year about it but the answer is still inconclusive as yet. But basically the 32/33 gearbox has a 1:1 ratio in 4th. But the 34 box has its 1:1 in 5th. So I have an "extra" gear in there to play with. So it should be much easier to select a gear in a useable power range thus reducing the effects of lag.

But having said that I havent driven the car with 2nd gear in over 6 months so I may forget I've even got it come tomorrow night! LOL. And Im guessing the 2 hairpins will be 2nd gear corners. But initially I will be trying them in 3rd anyways as my main objective tomorrow night is to come home with a fully functioning car - including gearbox, engine and panels. So if it means a bit of extra lag then so be it. Im not yet ready to test my direct 5th-2nd gear changing skills. I can't afford to break the damn thing again.

Bad news team. I'm unable to tune out the high knock that has developed. I'm pretty sure a dirty load of fuel was the culprit and the fuel system needs attention so clean and new filter plus clean the injectors, so while I should be good to swing by and offer support, i have now withdrawn my entry. I'm not going to compromise a good engine for the sake of a single event.

The O2 sensor gave me an extra 300 rpm at idle for some reason but still have the knock up around 100-140

Now to get the goodies together and get a tune with the lot. Reground GTR cams, 440CC injectors and the Z32 AFM.

Anyone got an early GTR/R33GTSt hand controller they can lend me so I can have more of a play? Time to sort my laptop and get FC datalogit.

My house mate is having a party at my place but its probably to far out of the way for most of you. I'm in parkdale. Also ferni you can borrow the digi display if I can get it in time. If somebody has a laptop we could data log if somebody can get the program to work. Had it working the other day with a mates one on the home computer and a cable through the window.

I have a laptop and am bringing it to access the laptimes over wireless, your welcome to use it to log some data as well if you like

do you have the serial cable? what serial cable do you need? female to female 9pin?

Anyone from the S.E Suburbs want to meet up to cruise to this together this arvo? (mainly because i suck with directions and will probably get lost :) )

its easy. Just get on the Calder Fwy and start driving until you see the Thunderdome. :)

I think it was a good day out, .....well this is coming from someone who didn't participate but we still enjoyed ourselves, especially watching Troy who got sideways on the 3rd and second to last corners a few times, Andrew with his 34 for obvious reasons, ferni who spun once or twice, and that guy in grey 32 with the RB26 who looked at one stage like he was going to run into the back of Rianto whilst braking for the 3rd to last corner- front left locked up it looked like :D....

I got heaps of photos but can't really be fu(ked putting them all up.... if any of you guys want a few just give me your email addy....

    • GCG is a good company, they're a major distributor for Garrett in Japan as well.
    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
    • Ok thanks 🙂 I will higly consider this. Any "known" company for a good reviews and experience to send that off? Is that CJ-motor good one? Or go straight to GCG site? I need to use VPN to even find some of those "shops" let alone access them 🙂 
    • You can literally put in as much WMI as it takes to quench the combustion totally (and then back it off a little, obviously), and it will keep making more and more power. The power comes from the cooling effect of the water (and the meth) and the extra fuel (the meth, which also has massive octane). It is effectively exactly like running E85. One might be slightly better than the other, but they are damn close. But with either you can lean on the boost or the timing (or both) waaaay more than with just petrol and the results are similar. Here's the first thing I googled for an anecdotal bit of evidence. Can't access the attachment without being a gold member, but it is there for the getting if able to, or searched up elsewise perhaps. https://www.hpacademy.com/forum/general-tuning-discussion/show/wmi-vs-e85/
