Piglet's Rebuild Of His Busted Tomei 2.8


Recommended Posts

How many boxes do you go through to find "the freak". It's a prick of a job at the best of times.

I'll pick Mick Hills stocker in and turn it down. No trackdays, no hard driving. See what's busted in mine and make a decision.

I really need to drive a dog box to see what the go is with them.

Buying a second hand box is like buying a second hand engine, always a risk so u need to make sure it's not a grenade. Buying new is ludicrously expensive.

I'll keep my eyes peeled if I come across anything.

I'm on my 3rd one in 6 years.

I just sold my broken box, the guy pulled it apart and only found a broken selector, gears were perfect.

In the 3 boxes I have never stripped a gear.

All damage was done at the track so I'd say a good cooler would go a long way.

Interesting Dave.

Although, you're RWD there is a bit of a "fuse" there.

Gotta get it out and strip it. Maybe in a few months when I get some motivation back! Haha

I couldn't imagine a dog box working that well on the street. You need to be fairly brutal with them otherwise you'll just wear them out and be up for about $5k per year in rebuilds. They just don't cop slow and steady gear changes well.

470kw will trouble a ppg too. Mine was cactus once I started pushing out over 400kw.

A helical you're referring to?

So what's the option?

I'm not keen on pulling it out every year. Forget a holinger or sequential as that would be in the same boat, would it not? OS doesn't seem upto the task (not just in my case either). R34 6 speed?

Put -9's on the car?

PM XRATED, he has had a helical for years now, not years of driving, but still give you an insight.

You are always going to be in a boat :P

First hand.

I owned a straight cut dog engagement PPG box for about 4 years. Drove it occasionally on the street, mostly in tarmac rallies etc.

It was rebuilt/refurbished every year without fail, regardless of how it was treated. They just don't handle power as well as people say.

Paul's car will certainly stretch it's limits with 470kw on tap.

These boxes prefer to be shifted hard, the slower you engage the dog rings the more damage you do to them and the gears. It's not always apparent until you pull it down just what slow shifting (street type driving) does to the box.

I sold it and went Holinger. My Holinger is helical, not sure if they all are. It's quieter and easier to drive at any speed without doing damage as a result.

I rebuilt my Holinger pre WTAC and parts alone was $5k! Nothing's cheap or bullet proof when you're chasing big power unfortunately.

There's no simple answer, other than keep saving your hard earned....

PJs Helical dog has had one dog ring changed in all the time he has had the box in his car.

75% is street driving plus countless 10,9 and 8 sec passes.

His car hooks better than most AWD :)

    • Harness update time have had great fun and learnt so much already so far with this project. I started off making both the ignition and injector sub harnesses in the hope any mistakes i made here aren't as hard to undo and learn from as the main harness.  A cool comparison of the old harness using presumably TXL wire and the new which is using Tezel. Also opted to use DTM plugs to keep the whole setup as neat and tidy as possible and tucked the wiring under the coil bracket to try and keep it all from sticking out too much. Although the injector harness, I'm not overly happy with as I'm still using the rubber boots that are supplied with the type of plugs it just looks ugly and sticks out like a sore thumb with the white identifiers so a slight redesign may be done.   Then it was main harness time and most importantly trying to route it nice and away from the heat it will use the OEM heater hose routing which is no longer present to keep the harness up high and secure. it's amazing how much smaller this harness is able to be compared to the old one. plugged everything into the emtron and with the help of the tuner again attempted to start it up and instantly fired up and running smoothly on all 6 which was a big shock to myself. So still some routing and adjusting to be done for the final fit up and installing a knock sensor harness plug which is in the post all has gone surprisingly well.     The old harness for shits and giggles.
    • They do that at random every now and then, with almost no detectable cause. Mine has done it a couple of times (over 25 years!!). Never worked out why.
    • I don't post on here and have been lurking for some time now. Many of the topics have helped me out more times than i can count. I was racing yesterday (11/9) and blew a front right CV shaft. I have spares so I popped a new one in. A thread i read previously said to check the engine mounts if you blow a front CV. Upon inspection, the front right mount was completely separated from the upper plate. This discovery saved me time and money, because i would have blown another CV if i went back out. Just wanted to thank you guys and wish everyone luck with with their builds. (Now if we could only come up with a solution for my power steering belt flying off after hitting the rev limiter, lol)
    • Either way he still need those style of spacer to go into the manifold because the photo he currently has is not going to work 
    • You can just get the injector bosses, which allows top feeds to fit. He can use the same injectors without issue, like these (another option): https://rocketindustries.com.au/af59-2210-rb25-fuel-injector-inserts     The Racework ones look a bit better: https://www.nzefi.com/product/raceworks-lower-injector-mounting-boss-kit-for-r33-rb25det-s14-s15-sr20det/   You could also just get a similar kit like the Radium one by Plazmaman: https://plazmaman.com/product/nissan-rb25det-r33-billet-fuel-rail/?srsltid=AfmBOoogfYq49X0fu2Wdbf8yOf6zt9egyPAif_gn3Qr3G8hzAphhTgOkO70
