R&M Racing BMW M20 Adjustable Camshaft Gear

I clicked on the site to see if there was any more information on the new gears noticed something you guys might want to fix.

I know you all probably think we havent been getting these gears back, but in one week these gears will be back up for sale and they are the BEST gears yet. Lighter then our last Version 2 Design. The marks are CORRECT on this new design unlike EVERY other gear out there on the market that I have seen (yes, including IE). At R-M Racing we only have two employees who have many years of professional experience in HANDS on motor building. By keeping our employees limited to skilled professionals, we GREATLY reduce the chance of having "Bad Parts". Every part that we sell, we have done RIGOROUS tests and spent countless hours inspecting and perfecting. EVERY SINGLE product that ships out of our warehouse gets a complete hands on inspection by the owner of R-M Racing to ensure that it is in PERFECT condition. We stand by our products. Try and ask the seller of that ebay copy of our gear how to install it. He will probably have no idea. Ask him where the cam is located on an e30, his answer will probably be that it is "under the hood".

This batch of gears was worth the wait, I can assure you. More information to follow.

Wow, it even reduces shifter throw!

Yet marks are still wrong.

Good news then. I was also looking to buy one of RM-racing gears. Just seen they were sold out and keep looking for some that arnt 250$

My twin cam engine is taking alot of money and the ix headgasket blew so why not deck the head .030...

you'll want to replace the hardware on the gears sourced from ebay/IE. the RM-racing gears were a little different. People have had the cheaper hardware shear on them, obviously not a good thing.

also, not sure what you guys are shitting on - they don't have any for sale right now?

I got mine from IE for $88 shipped.. same part..

I have yet to install it, but am expecting a noticeable difference considering my complex(ish) setup:
'89 m20b25 block w/ 885 'i' head and euro 323i cam
m20b23 crank (76.8mm stroke vs. 75.0mm = 2554cc, approx 10:1 c/r)
.. sort of like Alpina B2 ;)

the 323i makes peak power @ 5300rpm, but the 325i makes it @ 5800rpm..
we're thinking by retarding the euro cam a couple degrees, it should push the powerband back up to the 5800 or 6000 rpm mark..

if that doesn't work, its Schrick time - we're just gonna have to give up the coolness factor of using the euro parts that were lying around :(

So again, this is only to optimize the current setup..

hurry up!

Sold out?

currently yes, but we are currently having some more manufactured. They should be in stock in a week or two. We will keep you updated.

bump

[r-mracing]

only one of these left in stock! let your friends who dont have one yet know! :)

you can have a little bit more top end (retarding the cam) at the expense of bottom end, or some more bottom end (advancing the cam) at the expense of top end. It doesn't really matter if you are turbo or not, the effect is the same just magnified a little bit.

There's no free lunch, but you could shift the torque curve to the RPM range you use the most. so on a street car, you could advance it a little bit, and on a race car, you could retard it.
