for photos of head gear for rb25det

:P

stupid home loan has grown by 4k by the end of december 'cause of these parts fitting and tune LOL

i heard redline shockproof for jap cars is rubbish

yep as i have said befor it stuffs the syincros (spelling) i know 2 people that put it in when i told them not to and both their gear boxes blew

There are many who claim the same.

General comments are : it quietened down my box or improved gear selection but ultimatly the box shat its self and the mechanic said dont use redline.

I have not used it so I dont speak from personal experience.

yes it does quieten it down when the box is almost stuffed anyway but its just a bandaid and it will go

Ok, so your mechanical experience tells you this or you just going by what people have told you. It wouldn't happen to have anything to do with the history of the box or the way the box was treated would it?

Shes right, even if she might have heard it on the grapevine. Certainly the age and abuse of the box come into play, there is no question of that, however theres also no question that the shockproof crap destroys synchros. My mechanic (who is different to Kellies mechanic incidentally) said the exact same thing when I took it to him for the first trans service after I bought the car. He drained it and put in conventional oil (aka not the blue shit) which made the synchro issues more noticable. Basically the redline stuff cushions the blow when the synchros dont mesh. You feel it more while you have conventional oil because it has a different viscosity and density. When you have the shockproof stuff, its still doing the damage, u just dont feel it.

There was even a notice on the redline website for a time which advised NOT using shockproof on any synchromesh gearbox. Its pretty much meant for dogboxes (not sure about straight cut boxes).

In either case, my box is shagged. I'll be getting a replacement 33gtr S2 box but I sure as hell won't be using anything that looks like smurf diarrhea to lubricate it...

I'm just sick of alot of people puttin in their 20cents worth without any clue wtf their talkin about...

Helping for the sake of helping, It's not helping if it's incorrect information..could cost someone an arm and a leg.

This is not directed at the REDLINE argument lol

7 Litres! lol

AGREED!!!! I bet 50% of the people on here havent even got their hands dirty once while working on a car..... and go by what the twit at their local autobarn (who also has no idea about cars) advises to use... then further along that word gets passed along to more unsuspecting and out the know people as gospel...

WE WANNA SEE PROOF PEOPLE!!!!!

Sorry bout ya car craig :) know ya loved that thing, but like steve said, good thing nothing like that happened when it was yours - but then again you prob wouldnt of been driving like a dickhead like he was. Ahhh well.

Did you get awesomely drunk last night? bahaha :banana:

So in other words it doesn't damage your box any more than conventional lubricants, it just stops you from hearing your damaged box.

I'm not sure about that; for a definitive answer I'd have to run scientific tests, requiring brand new boxes and a sampling distribution of at least a dozen cars ;P

However I wonder if the viscosity and pressure differences might prevent the synchro from aligning correctly and then causing the problem. The main thing I see as being a downside with a synchro crunch you cant feel is that u cant adjust your shifting to compensate (ie meaty fist vs letting the gears slide in). On an 18 year old box like mine, theres no definitive answer but I really do trust my mechanics word.

-D

Generally excessive pressures can cause pitting to increase in alot of cases, Thicker oils tightens tolerances etc...I'm no expert but a car gearbox gets jerked back and forth alot which you'd think a thicker oil would stop alot of shock value in the backlash. But at the same time, The thicker oil, wouldn't create a higher pressure between the gears creating an increase in pitting/wear etc..At the end of the day, the harder you smash gears, the more power you place through a box the higher the pressure, the more wear anyway. Nothing stops age and wear and tear destroying a box, It's self distructing from day 1 as the case hardening slowly wears through into the gears. Most of the boxes we use, the damage has been done.

I hope that made any sense at all

well, i got a msg from damo friday arvo, pretty much telling me he seen

a 33 very similar to my old one, on the back of a tow truck, in bad shape....

so

i msged the young fella that bought it, and asked how its going blah blah and i got spares for it blah blah

no reply :banana:

and last night, got a phone call from my mate, telling me he seen a black 33 on the back of a truck

on friday night, all smashed up, badly, amd he is 99% sure it was my old one :)

what a dick head.

im pretty devo, but oh wells. i still got the money from it atleast.

I dunno man, it looked like yours, but definately had Koya rims, im 100% on that.

I hope that made any sense at all

Yeah it made perfect sense. I suppose thats why if you have shockproof and you shift like a ham fisted git then you might have some problems.... but if u drive it normally, maybe it'll be fine? Not sure eh... we need 10 people to get rebuilds and volunteer so we can test the theory (and write this clause where we both dont pay for damages haha)

    • When you pulled it off, there is no signs of blown head gasket? Is it possible you have some other issues going on? Possible cracked blocked? Or do you think it's straight up lifting the head? Did you check what the head was torqued to before pulling it down (To see if possibly they're stretching, or starting to break threads out etc)?
    • Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.
    • If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
