Danny's R34 Gtt Build / Diary / Log

[vetter2769]

Motorkhana happened, twas awesome.

Nothing broke, it held up really well, water temp didn't go over 94, and oil 95.

Decided to get somewhat more serious about track work, its way more fun than owning a loud sound system,

so old mate Sean came over and we started stripping her down.

All up including boot liner, subs amps head unit 4 speakers a tv and a ps4, it weighed around 130kg!!

noticed a difference in performance after this!

Still gotta do something about all that dynamat, it must weigh a tonne.

Changed spark plugs today coz never done it before since owning car, put in BCPR6ES-11,

Just heard from Scotty that my intake pipe and injectors are on their way, so all thats left is to see Tao at Hypertune to have my stock turbs high flowed.

At this stage I owe a thanks to -

TDR tuners in North Geelong, put a decent tune on my piggy back system.

SAU - tutorials on the forums, good advice, and chit chats with members.

Auto Pro Drysdale - for supplying me with my oils, filters, fittings, and all other random things for a discounted price!

TAS weld Moolap - for welding on intercooler (macko job).

Jessie Street - Because Jessie Streeter is a fkn BAWS.

Dad, and all my mates for pitching in.

and probably some others. Thanks to you guys for getting me where I am right now

Great Ocean Road cruse coming up this weekend, then I think I'll pull the car off the road and install power fc, z32, injectors, high flow turbo, and then put it back together and get it tuned on E85.

More updates soon.

Make sure you gap those plugs down before you wind the boost up

[vetter2769]

When the time comes for a tune I'll have a fresh set gapped down to .8

Plugs might get fowled during tune though?

I wonder if fouled plugs would affect tune? I'm going through race pace so I doubt it will be an issue.

but for now running 11-12psi so she'll be right

[gtr jet]

Nah, you'll be right. Just throw a fresh set of .8 plugs in before the tune and you'll be good to go.

[vetter2769]

Things are moving along faster than expected, had a friend help me start re-spraying the bonnet, front bar and lip (still got from 1/4's and side skirts to come) just to remove any stone chips and crap.

Embedded the top gear logo into the paint, just trying something new. turned out sweet!

And while he was doing that I started removing my turbo - taking it to Tao tomorrow for his high flow service.

Also will install everything form here, injectors, z32, power fc, waste gate, earls braided lines etc etc...

Then throw it on a trailer and take it to Race Pace.

[vetter2769]

Slight change of turbo, not getting my stock OP6 high flowed because full boost by 4k rpm is too laggy for me. So found a 21U (r33 standard) and am having that high flowed instead (full boost by 3500rpm). going to race pace wednesday

Who's highflow didn't make full boost til 4000rpm? I'm sure that can't be right, my SS2 makes full boost at around 3700rpm and it's low mount internal gate

[Artic Choc]

^ your lucky buddy my ss2 makes full boost at 4000.. mine has a few restrictions though.. dan and i spoke to stao in person he said his op6 highflow will make full boost at 4k rpm

Same here, my low mount stock mani ATR43SS2 is currently making 275rwkw on 98, full boost at just over 4000rpm. Certainly a lot less responsive than my stock OP6 @ 200rwkw.

No build thread at present but here's the spec list and dyno sheet: http://www.sau.com.au/forums/topic/55845-rb25-turbo-upgrade-all-dyno-results/?p=7370873

[vetter2769]

So had the car tuned on E85 at RacePace, the car came out with an impressive 300+ mw's and some incredible torque figures.

The car was making full boost just like a standard turbo!

Went and did a track day at sandown and ran a best time of 1:35, and absolutely cooked the brakes, so upgraded to EBC track pads (blue stuff)

Went to Phillip Island with the new brakes, and they worked a treat.

Ran a best time of 1:59

I've made other minor changes like changed the exhaust system to 3" pipe into the 6" cannon, makes the car a lot louder.

and coil overs, I'd like to do a beginners drift day to see how I like it so setting up the suspension and handling accordingly.

Thats all for now, more updates to come soon

[timmy_89]

Nice build thread mate. Good to see you finally moved on from the stereo
I can't make too much fun, I went through the same phase back in the day, just not in a Skyline haha. Nice responsive power figure from the setup too.

Besides trying out some drifting whats the plans? Personal recommendation regarding any track attendance, besides practice practice practice, would be to chuck some bigger swaybars on there. Made a world of difference on my GTT

[vetter2769]

Hey Tim, the next plans would in fact be sway bars, I've been looking and researching them recently, was going to get a thick 27mm for the rear to really get it sideways, I'm still undecided where I want to go next, I don't want to drift (this car) professionally coz it will get wrecked! I just want to do a beginners/learners day and give it a decent crack.

Otherwise I'd have to say I really enjoy motorkhana, its not as serious as track days, also I'm going to run it down the quarter mile soon to see what it can do

What size sways bars did you buy? thoughts on going for a 27mm for rear straight away?

[timmy_89]

Good plan

I started thrashing my GTT with motorkhanas, progressed to drifting, got sick of breaking things and have now moved to circuit/hill climb/supersprint.

I have Whiteline 24mm adjustable front and rear. The rear has always been at its stiffest setting (made a huge difference when I was drifting) and the front was in the middle to begin with but I have stiffened it right up now too since moving more towards grip.

If you have any questions don't be afraid to shoot me a PM

[peterw]

Nice build man. You're doing a lot of the things I'd planned to do to my GTT (but never got around to doing).

[vetter2769]

Thats good to hear Tim, I thought the 27mm for the rear was a bit too much, is yours a S2? do you have the helical diff? I thought I had shagged it out at a track day when it was single pegging out of corners, turns out it was just shit grip/ to much low pressure. You ever had any dramas with your diff?

where did you get your sway bars from? ebay?

And thanks Peter

[timmy_89]

My stock diff was shagged so I have fitted a Nismo 1.5 centre. Great upgrade if you are doing anything sort of track work in my opinion.

I honestly don't remember where I got the swaybars from sorry.

[vetter2769]

all good, ebay has them at decent prices, and is your 34 a S1 or 2? I believe that the S1 had some crappy mechanical LSD like the r33 but the S2 (mine) a more betttererer helical that was apparently made by true track?

[timmy_89]

Mine is a 1998 model so it would be an S1. I believe it had a torsen diff? Not too sure, didn't look in to the stock diffs too much, just knew it wasn't sufficient for my needs haha.

Ebay pricing is usually pretty reasonable. Someone on SAU (I think it was sydneykid or someone?) sells kits and can get the swaybars too, otherwise maybe chek out the SAU traders as well.
