if i was going to run about 350whp on my daily driver through the stock ITR tranny with a turbo....what could i do to the tranny to make it stronger?

or does anyone have experience with a better, stronger aftermarket tranny?

any companies that people have experienced to make better synchros, trannies, gears?

all comments welcomed

this discludes all talk about clutch, flywheel

this is direct tranny related items only

thanks

I have no idea what you can do to your tranny, but you can start off by buying my turbo system

and selling me your JRSC system Azcheron

 

well, as a daily driver, i dont think you will be constantly revving at 8000 and downshiting to 8000 when u turn, so at this point, i doubt you would need it. i dont know how weak the ITR tranny is, but my h23 tranny held up fine with 300 whp. h22/23 trannies are known to be weak too.

what you might want to look into a aftermarket clutch to hold all that torque. you could also cryo treat your synchro's and such. i dont know how much it costs though.

 

Wait, I thought you were selling the R?

 

You should look into installing the carbon coated syncros, shifts are alot smoother and works a lot better when high reving

Spend your money elsewhere. Unless you're running slicks, you should be OK with just a clutch.

Yupp. I've seen OEM trannies with 400+ hp with nothing more than axles and a good clutch hold up fine.

 

What Chris said.

I did some research on this a while back ago, and the only company I found that makes stronger trannys for the ITR is Xtrac in the UK. http://www.xtrac.com

It's extremely expensive though. 13000£ I think they go for. But they are able to take all boost you can throw at them with no problem.

 

Why not just get the dog box kit from http://www.housemanautosport.com/ ?

Much cheaper.

im sorry, but i dont agree with that at all

im pretty gentle on my car

but i do whip it around on occasion, and with the high redline of our cars with a lot of power and agressive clutch and flywheel....

ive already replaced my synchros twice

my clutch and everything else is mint after driving hard for many miles, but my first synchros went after 45k, then second set went after 20k with the JRSC on

 

BTW im referring to an ITR engine, but not my ITR. The one for the future project

my ITR is still for sale

 

Unless you drop the clutch with slicks , the ITR tranny will hold 400+ no worries.
Mine is stock with a quife and holds 500+ no sweat.

That's fine. I'm nowhere near gentle on my car and have 93,xxx miles on it with no grinds or tranny problems at all. The only trannies I've ever seen totally destroy themselves were with insanely high hp.

Maybe there's something wrong with your driving style, because power doesn't wear out synchros, shifting does.

Quaife claims that the stock ITR LSD can't handle high horsepower.

Yep....

I've never broken or worn out a synchro in track use

As I'm sure you were able to discern from your email correspondence, Quaife does not appear to have any empirical evidence to support its claim, and is presumably using such statements more as a marketing ploy than anything else. Of course, one would indeed expect a performance after-market differential to be stronger than an OEM unit, but for the great majority of individuals, the ITR LSD will likely be completely sufficient.

DING DING!

Winner!

 

power doesnt affect synchros?

who told you that?

i am a very good driver

i dont down shift more than a gear at a time

when i down shift, i always rev match

and i cant be that bad a driver, since my clutch and flywheel look great

synchros in our cars is a common and known issue

those who havent had the problem are lucky

many many many posts about trannies and synchros on every honda forum ive ever been on

anyone have experience with any of the above mentioned trannies or coatings?

where to get and how much?

If you abuse your transmission

Or if you are just rough with it - anything will break given enough abuse and time

And dont change your gearbox oil often

Given the state of tune of your engine w/ the JRSC...... I would suspect you treat your transmission the same way

Its not a "common" problem at all if you excercise a little care

Take care of your equipment and it will take care of you

And stop posting like this.
