Aaron,
How would the GSC R2 do on this car, dont see you guys using much of the R2's and also care to post up the evoscan log of the dyno pull like you have done in the past? its awesome where this thing is making power at!! what stopped you from going to 40ish psi ?

I use R2s every chance I get. This motor and head is 4 years old so it predates the R2. It would make more power under the curve and spool faster since they are meant for this exact build. The customer didnt want to g higher than 37psi since the crankshaft is OE and the whole mess is old and well worn in.

R2s are 12.1mm lift and the secret is the ramp rate. Each cam has its place, the S2 is smaller turbos and lower powerbands (8500 and under and/or big motor), the S3 is for smaller motors and over 9000, the R2 is for big motor/big turbo but under 9000.
The R2 isnt really between the S2 and S3 its more along side the S3.

I will send you one question via private message in order to maintain the integrity of the thread.
The "ultimate" ratio transmission is just the Evo 6 stock gear ratios. In the USDM market the VIII was geared one way and the IX the next. By combining the IX first with the VIII 3 and 4th you end up with the stock ratios for the 6. Least amount of drop between gears and the most mph in 4th gear of the bunch.

Page 2 highlights it, they list 4 and 5 as well but as near as I have found in JDM CAPS its just the 6.

Excellent power out of this car on fairly low boost. How much further do you think you can push this setup if you refreshed the motor and kept the Eagle rods? 850awhp pushing it?

Yes IX 5th is technically the Ultimate Ratio box...some people use the 8 5th for mileage reasons. Theoretically this motor can do 850 but it wont ever see more than it is at. There are plans for an SLR2.2 and a Super 99.
Do you think the super 94/99 is a good for a twinscroll setup with the 2.2 LR ? I'd be interested in this setup maybe after some dyno results

Havent tested it in a twin scroll yet (will happen before too long) and I only have one 99 car on the road. The results from it are extremely promising.
