All good stuff. For this application I am planning to use a twin turbo setup so blowers are out and blower RPM becomes a non-issue. The reason for the high engine RPM is to reduce the boost required for this application. At 9000 rpm I need a boost pressure of about 24psi. If I reduce the RPM...

I've been off the air for a while. My latest plan, following advice from others, is to keep the bore std. and reduce the stroke to 72mm. As was pointed out earlier this will reduce both the piston speed (ave. 25 to 21.8m/s, peak 40.7 to 35.3 m/s) and accelleration by about 14% over the std...

There are a number of reasons that I would prefer to decrease the bore. 1. De-stroking would require a billit crank which will not be as strong as the original forged unit. 2. De-stroking will provide less low down torque and require longer rods to achieve 11:1 comp. 3. Having a decreased...

Yep. Race rules. Once the engine goes FI then a 1.7 equalisation applies. Hence to race in the 6 Litre class the capacity needs to be around 3.5L. I could have gone with a 3.5L V6 or S6 but the V* would be more reliable (9000 RPM, 20psi, 11:1, methanol).

Does anyone know if it is possible to get new sleeves (wet or dry - prefer in Aust.) for a '98 1UZ with an ID, bore diamater of 82.0 or 82.5. I need to change the total capacity to approx 3.5L.
