Piglet's Rebuild Of His Busted Tomei 2.8

[Piggaz]

I'm from Brisbane Qld, sorry for the question as I haven't read my os giken booklet. But once you engage reverse by pulling the lever up do you have to put the lever up again to go back to neutral or do you just push the lever down as you would when engage the next gears?

From reverse you still have to hold up to neutral. From neutral you just pull back for first.

What did you do to fix it, Pete?

Ditch it?[/quote up went to a anodised one

It definitely changes the car from the tall geared OS 5 speed that I had in it. "Woke it up" as such.

You don't need to run the OS clutches, but it takes out one less headache when putting it all together. I looked into trying to salvage the coppermix as they really are THE clutch to have in a road going GTR. (Mine was in there since 2005 with no service/rebuild at all). It was all too hard. For starters the coppermix was a pull type, this box only has the bosses for a push type, then there was the bigger input shaft issue. The R3C is awesome, much better than expected and NOT how I remember the R3C in other cars I've driven. The pickup/friction point is quite low compared to the Coppermix which takes a bit of time to get used to. Apparently this is the new type. What they have changed, I'm not sure.

You will need to supply your own transfer case.

There are 4 gear options available. I went option 2. Assuming a 265/35x18 tyre and spinning to 8000 rpm each gear will go to

82

118

160

200

234 (same as stock as its 1:1)

310 (same as a factory 5 speed as its 0.757)

You're basically slotting an extra gear in before the 4th gear in a factory 5 speed box. If that makes sense.

With the box, I bought;

Box itself

Modified cross member

Bent shifter

Clutch

Release bearing

Clutch aligning tool

There is a bit of crashing and banging at low rpm, but that's just me not getting the timing 100%. I've only driven 60 kms or so with it so still very much a noob. Up high and drive it like its stolen, smooth as silk. Just slides into the next gear, you don't feel anything through the shifter. As quickly as you can pull back on the gear stick its in. I've found preloading the stick before you lift seems to work well too. I'm still clutching in ATM but as time goes on I'm sure I'll be able to do the no clutch/ lift throttle technique. I'm obviously not tuning a strain gauge - yet. I wouldn't like to daily drive it but for a weekend car it's great!

Thanks a ton. This post will help a lot of other crazy people like us!

Have been a little quiet here lately. This fuel gunk issue has really given me the shits. The baskets in the injectors kept filling up so in the end I decided to rip them out for the journey to Richmond where the next round of goodies are going on.

EFR 8374 1.05 ass end. See you later -5's, you have served well.

6 boost twin scroll manifold. 38 mm Tial gates will be used. Still waiting on those guys.

In light of this fuel issue, I've gone mega overkill. Ordered three of these Fuelab filters. A single 75 micron filter pre surge tank with twin 6 micron filters post pump. I'm going to "Y" it and run the filters in parallel seeing that the filtration is so fine. A set of stainless steel internal 1700's will be going in instead of the 2000's.

EFR speed sensor. It will be Intersting to see what speeds the snail is spinning.

Display for the sensor.

Holley Dominator 1800 fuel pump has been purchased and getting rid of these 044's. A new stainless surge tank will be made and will live in the boot.

All intake, exhaust, surge tank fabrication will be done by Mick_O.

Some Nismo diff bushes have been bought also. I have solid alloy ones in there ATM and they're bloody horrible.

A catch can has to be made for the OS88. It just spews oil out of the breather when giving it some on left hand corners. Poor form OS!!!

The secrets out the bag now big dawg EFR FTW!!! Really can't wait to finish that EFR setup on that shitbox evo of mine and get into this thing

How long does a turbo swap take? It's not the end of the world.
