Hello forum users,

I posted this on the General Automotive Section as well.

My current Evo 8 setup produces 260 awkw on a built 2L engine. My plan is to upgrade the turbo and the upgrade should produce around 370-380 awkw on E85.

My question is whether the standard 6 speed gearbox would be able to tolerate the above mentioned power level?

I have never launched the car and do not intend to in the future. Will the gearbox be able to cope with the power in normal everyday driving?

My preference is not to convert to a 5 speed or a dogbox.

Any advice would be appreciated.

So it's a 8MR?

I'm surprised it's held together as long as it has at that power level. It's definately a weak point once you move over from the stock turbo. It's why I'm gonna keep stock turbo in my 8MR, will be track day reliable (enough).

Anyway if you wanna keep the 6 speed, NEAT Gearboxes do a upgraded 6-speed box basically fixing the major flaws the 6 speed has, it's around 5k. So give them a call.

Or you could just put a 5 speed in and keep the 6 speed in the garage for when needed, that'd be a cheaper option

My mate makes 270kw on a 2.3L stroker with an FP Green and runs a twin plate clutch.

He is absolutely f**king ruthless with the thing. Does multiple limiter launches every single day and absolutely smashes gear changes unbelievably quickly. Has never changed gearbox oil and the car has about 100,000km on it (evo 9 btw). But seriously, he has zero mechanical sympathy for the thing and it has never had any issues (except for shitting a rear diff once)

Runs a variety of tyres from rubbish to AD08R's on it, so the driveline would be getting a huge workout. His gives me a lot of faith in the standard driveline. I think with 350kw, a nice friendly clutch and some sensible driving you should be fine.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
    • What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
