Oh. Did it last long before it broke?

What trans did you end up with after that?

Stretching my memory now but about 10,000kms.

After that I had a hissy fit. In went in a OS88 sequential then a PPG sequential.

The extra gear is a game changer.

Well that is not a sign of good quality.. 

Understand, but not so nice to drive on the street I suppose and out of my price range..

Sequential Is fine to drive on the street

What are you thinking makes a sequential shit to drive on the street?

About the ONLY thing I can think of, is if you're wanting to be able to roll up to lights in third or second and pop it straight into neutral, or you want to come down two or three gears, say out of 5th and back to second, but they shift quick enough it doesn't really matter

Just thought they where clunky in low speed, like tight traffic. 

Anyhow, they are out of my price range.

It'll only be as clunky as you are with the clutch pedal...

Hi,

I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset?

At what power level and use did yours brake with or without billet plate?

Thanks, Oystein Lovik

Which way are you leaning?

Not sure yet. 

Was considering speedtek because it was rated to 800hp, but when I did some research about him I don't think I will go for that🤣

So maybe giken gear set, but I'm afraid it won't be strong enough🙄

You’ll be very upset when you bust that too not to mention the gearing totally sucks. Don’t do it.

Yes, I know🙄 but the sequential is not in my budget... don't want to reduce power neither, so looks like I'm stuck in the rabbit hole🤣

Just put skinny tyres on it.

[Duncan]

Or shift gently. While the risk goes up as the power/torque does, not everyone breaks gearboxes.

 

[cosline]

Your both right, it may hold a bit longer then. 

Soon I need to change the synchros, should I fit the billet plate while I'm at it? Or just a waste of money?

A wise man once told me, "Anything you enjoyed wasting was not wasted".

[r32-25t]

Time to decide what’s more import, your power level or your budget because you’re going to struggle to keep both 

[Butters]

I know people cry at the price of the Getrag 12-14k for a conversion now, but it really is a nice mid point. Not going to get change from 10k on a gearset installed.  $30k++ for sequential.

 

I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.

Remember kids - if you can't afford to buy 2 GTRs......

[Murray_Calavera]

I don't understand what the issue is with, turn the boost down and start saving $$. 

As soon as you can afford the supporting mods, turn the boost back up. 

If the car is running fine, enjoy it. Turning the boost down isn't going to kill you.

Like others have said, drop the power to give your drivetrain a % of reliability until you can up the drivetrain reliability 

It isn't rocket science, build power to the weakest link with a % of safety

Whilst upping the the reliability of the drive train is costly, there's no point in having the engine make big power if it keeps eating the drivetrain....ask me how I know, I had the tow truck on speed dial for a few years, and I spent huge amounts of money fixing issues and breakages that really would have been cheaper in the long run if I did it right the first time

Me, I like a nice sized fudge factor, that keeps me off the tow truck
