Hello, I am looking at upgrading my cross-mission w/center plate to the PPG 1st-4th Helical Dog Set in about six months, so I am no rush for information. However, I would prefer to hear from those that have had first hand experience with the PPG 1st-4th Helical Dog Set. Looking to match this up to my GT-R (BCNR33). I hate typing, so for a basic idea of my baby's build;

- HKS Fcon VPro

- HKS T51R BB

- ARC IC 3 core

- Tomei 270 10.8

- HKS Crankshaft balanced w/ ORC Triple-plate and ATI damper

- Greddy Surge tank

- Fuel Injectors 1000 cc

- Bosch, Fuel Pump x2

- Tires, 245/45-17 Nitto (Drag only)

- Tires, 265/35-18 Dunlap RE-01 (Daily use only)

- Tires, 275/35-18 BFG Drag Radials (Daily & Drag use?/ to be tested)

:P

I run the ppg 1st-5th straight cut dog gearset in a gtr box and its a great piece of gear, drives nicely and can be street drivin once you get the hang of rev matching on downshifts. The upshifts are easy and never crunch if u let it slide in slowly or jam it as hard as possible. I never realised how slow a synchro box was to shift until i drove the dog set, its just on another level and worth every cent.

Im running 560hp at wheels in a 1700kg stagea and done heaps of rev limiter launches and never had any breakages, plus heaps of slamming gears and all is perfect. Only issue with the straight cut option is the noise is pretty loud if its doing any street duties, but you are thinking helical so thats no drama.

thanks for the response and your experience with the ppg 1st-5th straight cut dog gearset. have you had a chance to drive the PPG Helical Dog Set? if you have, how would you compare them?

yes a dog box is a dog box. straight or helical all the same.

unless you are dedicated to smashing thru the gears when racing i wouldnt sugest it. but from your specs your not mucking around!! got a dyno sheet?

ps.. the straight cut one is very loud!! i had a 100db exhaust and cant hear it at all over the box.. lol.

pps. unique1, you must tell me how you up shift in detail!! lol. evan though i havent driven it since nov 07......

Hey Dave, upshifting is a simple case of revving to normal range for a shift when cruising (say 3000rpm) and put clutch in and wait till revs drop to the correct revs for the next gear (say 1800rpm) and slowly push it in and it will literally just fall into gear. I had trouble in beginning trying to jam it fast but the slower the better if u not revving it out to rpm limit, it works a treat, only the downshifts i sometimes have an issue with, but got used to it in the end. I havent drivin the car with the dogbox for a good 3 months, its going into another car now so no street duties anymore, the neighbours can have some peace from the whining :)

no dyno info at this time and I had to do an unplanned rebuild. :( the rebuild has taken forever (more than a year) as my pockets are not lined with money. anyway, my baby will be back on the road at the end of the month or the middle of March at the latest. :P I am looking at having the tune set with the high boost set at either 1.9 or 2.0 with low boost at 1.7-1.8. really leaning towards just to play it on the safe side most likely looking at keeping high boost at 1.9 until I am able to get the PPG Helical Dog Set.

we have fitted heaps of these and i cant say enough good things about them , only problem is the price really .

cheers.

thanks for the info

>_<

Mate I have got 2 PPG gearboxes in both my GTR R34 and GTR R32 all you need to do is when driving on the street is to double clutch both up and down and no problem. If you are giving it full throttle as fast as you can push the clutch and change the gear you will never beat it, this is better for the gearbox as it is designed to be flogged. You will never break it unless you crunch the dog engagement all the time, they hate to be slow changed you have to be positive...

Hope this helps.

How long do they last between rebuilds?

There is no need to rebuild them unless you crunch the dog engagements with bad shifts, Run Shockproof lightweight oil and they are good for years. They are hard on the little nylon bush that sits on the end of the shifter that goes into the gearbox selector, keep a couple as spares and as they wear will be harder to shift, just throw in a new one and all good. Takes 1/2 hour.

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      By Murray_Calavera · Posted

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      By Duncan · Posted

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
