Anyone notice no lsd?

Does anybody want to explain the benefit of the straight cut gears?

Tweakmeister

Thanks for the link Reid - does Jamie have a website?

Sage's Website does have: http://www.sageracing.net/stor...59739 <-- pretty cool, but most of what I see are appearance parts

As cool as this is - I can't bring myself to drop $2000 on something with no other example of installation. It's unproven, and I can't afford to be the example...I've been trying to find more info...hopefully I can.

Does your firewall block google or something?

Lol...A search for his name (and similar variations) only brought up past racing results.

Here's my (unedited) reply from these guys (they sort of dodge my questions):

Hi,
Thanks for your interests, as these are straight cut, the soud is a little loud which you can use sound proofing to reduce it. The axle seal are not painted, it will last for a long time as long as it is well taken care of like regular transmission gear oil change, I hoep this helps, thanks ;p

They make that cool rally car transmission whine sound.

The reverse gear in all Integras is straight cut.

They don't require a thrust bearing - http://www.bbc.co.uk/dna/h2g2/A691030

Tweak, are you insane? Unless your car is drag or track only, this would be a bad choice. You will have to perfectly rev match every upshift and downshift in 3rd, 4th, and 5th(no synchros). Your top speed will probably be around 120 or so, and your car will sound like a jet engine on the highway... There are much better choices for a street/track car...

How much power are you making anyway? Why the need for such an extreme tranny?

If you're looking to upgrade, this would be a better choice - https://honda-tech.com/zerothread?id=1323820

Rev-match an upshift?

JDM Factor

The tranny will be fine in upshifting you can't really rev match an upshift, but the blips on downshifts are critical

Do I need to answer that?

My car is loud already, I can't imagine the high-pitched scream to be much worse

They emailed me back - claim 5 years on the tranny before needing a rebuild (recommend the best Redline fluid I can find).

The major appeal to me are the straight-cut gears, and the fact that it's a bolt-on affair.

I wish someone else could chime in with their experience - I hate being a $2000 Guinea pig.

JDM Factor

I think your wasting the money, what's so bad about the stock tranny? All that tranny is going to do is cause you a headache in the end. I think a 5 year claim on a straight-cut gearbox is b.s. I've never heard of straight cut box lasting 5 years, especially run on the street. If it was me, i'd say the cash for something else. If you want to modify the tranny, try going with ATS parts.

Tweakmeister

Who says I'm wasting money? I haven't spent it yet

Every post I've made has had some level of skepticism in it, and most of that remains. I don't buy the 5 year claim either - maybe 6 months lol. This is definately a developmental part - not a race part, and certainly no where near durable enough for street.

It's always been a dream of mine to get a really trick transmission for the car. The stock is amazing for being stock - but nothing short of an F1 or Ferrari F430 gearbox would please me right now...I consider this one a step in the right direction, but not necessary the best step to make.

The ATS gearset is awesome - it's probably the best route available for upgrading the transmission from stock.

JDM Factor

I think ATS makes a sequential gearbox for the ITR, for 10 g's. That's as close to a race type gearbox you can get!

Whats the advantage of running straight cut gears anyway?

JDM Factor

Straight cut boxes or gears have an advantage in racing because it's a lot more heavyduty, lasting longer in a racing application. They are cheaper to rebuild than most helical type gear trannys. It's just a simple and practical setup for racing. The disadvantages of helical gears for racing, is a resultant thrust along the axis of the gear, which needs to be accommodated by appropriate thrust bearings, and a greater degree of sliding friction between the meshing teeth, often needing specific additives in the lubricant. Helical is more suitable for street driving use.

Tweak, are you hardcore?

If you don't get this box, maybe I will.....
