Had my r32 gtst tuned by Sam aka Dr Drift yesterday and i cannot reccomend him enough. He really gets nothing less than the best from your car. I think we were on the dyno for close to 3 hours and he charged me for a bit less, so i was really happy. Not like other places that want to sting you for the last 5 cents they can.

Anwyays im sure most of you know his work is 10/10, here are the results.

This was achieved on stock injectors so it shoudl also silence a few critics.

When you look at the dyno graph you can see what i went in with and what i left with. What you cant see is the afr's that were all over the place with the chip i drove in with and how perfect they are with the chip i left with.

Made my day :)

looks good. Sam knows what he's doing :)

did you get that done up in brisbane?

what turbo have you got? Rb20 i presume?

Cheers.

Sorry, relevant mods to the RB20 are hks 2530, nismo adj reg, bosch 044 intank. Top quality intake and exaust systems help too. I think the stockers limit is around 160-170 but i could be wrong.

Anyone who gets the chance i highly recommend, i would truly be disappointed if i couldnt have him tune it again in the future. Possibly for some tomei poncams (stuff adj cam gears) and nismo 550 or 600cc injectors.

I also have fuel economy now !!!!

EDIT: yes this was done in brisbane, gold coast actually and was @ 17 psi

thats good power for a 2530!

and yeah, getting good fuel economy was one of the highlights :)

do you have a z32 afm too?

what are the air/fuel ratios like now, around 12:1? put up the graph if you can.

Yeah the air fuel ratios where as sweet as could be, around 12:1

I dont have any graphs with afrs on them, i was watching them on the screen though as he did run after run, tweak after tweak :)

How is your fuel economy now

how many litres per 100 km?

cheers

I dont drive it sedately enough to tell you sorry, plus i only got it done yesterday. If i could manage to drive it without flogging it then that might help. Its also my toy car so i only drive it a 5 or so times a week.

All i can say is its much better between 25 and 50% better at a reasonable guess.

Do you know if he emulates or does he burn chips ervery time he makes a change?

Not really (not that im a critic)

But you've obviously bumped the rail pressure

nismo adj reg

So its kinda hard to tell :P

If you hadnt bump'd the pressure then i'd pay a silence of the galleries :(

Oh... and Sam was getting Emulation last tiem i spoke to him (couple months)

So i'd say one burn @ the end and she's away

He emulates them for sure, very tidy equipment he has been developing for years now.

And yeah Nismoid the pressure is bumped up, it was really only significant because sam had never tuned that from stock injectors.I plan to get the injectors and cams before he is back next. That should enable me to find the limit of the 2350.

i've got a similar setup (2530/RB20) and i'm not making as much power but mine seems to come on boost full boost (18psi) about 400-500rpm earlier from what i can see on your graph.

Damn, that sucks, i really dont find it laggy at all though very compareable to the stocker. I have a Profec b spec 2 that opens the holds the wastegate shut untill it reaches .75 bar.

I dont think you can tell how laggy something really is on the dyno

My 2 cents :(

You'll find that most operators don't really start loading up the car below 3k so it doesn't give your turbo the opportunity to start building boost as it would on the street. On the dyno i hit 20psi by 4k, on the street it's more like 3200.

but think about what u just said, it that really giving u a good tune??

your gonna be tuning it for lower load points on the dyno then it hits the road and its using higher load point which wasnt tuned as well.

u got a dyno to simulate the road conditions and u dont use it to the full potential, i think thats abit silly.

thats my 2 cents, no disrespect to anyone.

Glad to hear your happy with the tune, I was :)

yogi - Most of the low to midrange has been re-done, some runs were loaded up down low, Mick's car has excellent transition from the 14.7 AFM when running on the factory O2 down to 12.0 as the car's generating boost.

    • Can perhaps see how the R33 appreciators would think so.  
    • Thanks, I removed the fuse and the relay from the car and made my own circuit with them to test them with a test bulb.  I will look for the wiring diagram and go from there.
    • Jdm DC2R is also nice for a FF car compared to the regular hatches of the time.
    • Now that the break-in period for both clutch and transmission is nearly over I'd like to give some tips before I forget about everything that happened, also for anyone searching up how to do this job in the future: You will need at least 6 ton jack stands at full extension. I would go as far as to say maybe consider 12 ton jack stands because the height of the transmission + the Harbor Freight hydraulic platform-style transmission jack was enough that it was an absolute PITA getting the transmission out from under the car and back in. The top edge of the bellhousing wants to contact the subframe and oil pan and if you're doing this on the floor forget about trying to lift this transmission off the ground and onto a transmission jack from under the car. Also do not try to use a scissor jack transmission lift. You have to rotate the damn thing in-place on the transmission jack which is hard enough with an adjustable platform and a transmission cradle that will mostly keep the transmission from rolling off the jack but on a scissor lift with a tiny non-adjustable platform? Forget it. Use penetrating oil on the driveshaft bolts. I highly recommend getting a thin 6 point combination (box end + open end) wrench for both the rear driveshaft and front driveshaft and a wrench extension. These bolts are on tight with very little space to work with and those two things together made a massive difference. Even a high torque impact wrench is just the wrong tool for the job here and didn't do what I needed it to do. If your starter bolts aren't seized in place for whatever reason you can in fact snake in a 3/8 inch ratchet + 6 point standard chrome socket up in there and "just" remove the bolts for the starter. Or at least I could. It is entirely by feel, you can barely fit it in, you can barely turn the stupid ratchet, but it is possible. Pull the front pipe/downpipe before you attempt to remove the transmission. In theory you don't have to, in practice just do it.  When pulling the transmission on the way out you don't have to undo all the bolts holding the rear driveshaft to the chassis like the center support bearing and the rear tunnel reinforcement bar but putting the transmission back in I highly recommend doing this because it will let you raise the transmission without constantly dealing with the driveshaft interfering in one way or another. I undid the bottom of the engine mount but I honestly don't know that it helped anything. If you do this make sure you put a towel on the back of the valve cover to keep the engine from smashing all the pipes on the firewall. Once the transmission has been pulled back far enough to clear the dowels you need to twist it in place clockwise if you're sitting behind the transmission. This will rotate the starter down towards the ground. The starter bump seems like it might clear if you twist the transmission the other way but it definitely won't. I have scraped the shit out of my transmission tunnel trying so learn from my mistake. You will need a center punch and an appropriate size drill bit and screw to pull the rear main seal. Then use vice grips and preferably a slide hammer attachment for those vice grips to yank the seal out. Do not let the drill or screw contact any part of the crank and clean the engine carefully after removing the seal to avoid getting metal fragments into the engine. I used a Slide Hammer and Bearing Puller Set, 5 Piece from Harbor Freight to pull the old pilot bearing. The "wet paper towel" trick sucked and just got dirty clutch water everywhere. Buy the tool or borrow it from a friend and save yourself the pain. It comes right out. Mine was very worn compared to the new one and it was starting to show cracks. Soak it in engine oil for a day in case yours has lost all of the oil to the plastic bag it comes in. You may be tempted to get the Nismo aftermarket pilot bearing but local mechanics have told me that they fail prematurely and if they do fail they do far more damage than a failed OEM pilot bushing. I mentioned this before but the Super Coppermix Twin clutch friction disks are in fact directional. The subtle coning of the fingers in both cases should be facing towards the center of the hub. So the coning on the rearmost disk closest to the pressure plate should go towards the engine, and the one closest to the flywheel should be flipped the other way. Otherwise when you torque down the pressure plate it will be warped and if you attempt to drive it like this it will make a very nasty grinding noise. Also, there is in fact an orientation to the washers for the pressure plate if you don't want to damage the anodizing. Rounded side of the washer faces the pressure plate. The flat side faces the bolt head. Pulling the transmission from the transfer case you need to be extremely careful with the shift cover plate. This part is discontinued. Try your best to avoid damaging the mating surfaces or breaking the pry points. I used a dead blow rubber hammer after removing the bolts to smack it sideways to slide it off the RTV the previous mechanic applied. I recommend using gasket dressing on the OEM paper gasket to try and keep the ATF from leaking out of that surface which seems to be a perpetual problem. Undoing the shifter rod end is an absolute PITA. Get a set of roll pin punches. Those are mandatory for this. Also I strongly, strongly recommend getting a palm nailer that will fit your roll pin punch. Also, put a clean (emphasis on clean) towel wrapped around the back end of the roll pin to keep it from shooting into the transfer case so you can spend a good hour or two with a magnet on a stick getting it out. Do not damage the shifter rod end either because those are discontinued as well. Do not use aftermarket flywheel bolts. Or if you do, make sure they are exactly the same dimensions as OEM before you go to install them. I have seen people mention that they got the wrong bolts and it meant having to do the job again. High torque impact wrench makes removal easy. I used some combination of a pry bar and flathead screwdriver to keep the flywheel from turning but consider just buying a proper flywheel lock instead. Just buy the OS Giken clutch alignment tool from RHDJapan. I hated the plastic alignment tool and you will never be confident this thing will work as intended. Don't forget to install the Nismo provided clutch fork boot. Otherwise it will make unearthly noises when you press the clutch pedal as it says on the little installation sheet in Japanese. Also, on both initial disassembly and assembly you must follow torque sequence for the pressure plate bolts. For some reason the Nismo directions tell you to put in the smaller 3 bolts last. I would not do this. Fully insert and thread those bolts to the end first, then tighten the other larger pressure plate bolts according to torque sequence. Then at the end you can also torque these 3 smaller bolts. Doing it the other way can cause these bolts to bind and the whole thing won't fit as it should. Hope this helps someone out there.
