Didn't know there was such a motor, I only know of the s52b32...

2.6 liters and want all the revs you can handle?

mazda 13b renesis. 9500 rpm redline and 260hp in race trim. older 13b-rew can do 300hp with an aggressive port job.

:pimp:

it's also good if you enjoy rebuilding your motor every 20,000 miles. :p

And using as much motor oil as you are gasoline.

sisnce you were saying best motor in na form @2.5 liters, maybe a bored and stroked
K20 would be awesome. or even an f22. just saying.

^^Still wouldn't compare to a worked 2.5l S14.

I think a honda k or f series motor takes the cake in this race.

any of you actually stop and think this kid, with 1 post has no idea what he's talking about and instead of coming up with cool solutions; a combination of all our wishful thinking, we should understand what are his goals, why he needs high r3v and why in the world a 2.5L... i smell poser and ricer.

so, guy, what's the deal, what racing will you be doing, what are your power goals, what are your money and class limitations?

i thought all those things too, thats why i never really replied. what chassis, what class, etc... the op never even came back to this thread anyway.

how about a destroked and debored s85? along with a CF monoque and a $40,000 steering wheel, wind it up to 19,000 rpm and itll make all the power you need.

Race in that class
I would love to

so much misinformation....

my rx8 burns less oil than most e30s. about a quart every 3000 miles. its not even an issue. i never add more oil. i just change the oil, because its time anyway and im back to full.

and a rebuild every 20k miles? lol. i know a few people that have 15-20 2 day track events, and dozens of autoxs with over 100k on their motor. quite a lot of rx8s with 60k-80k miles with dozens of track events. its a newer car, so not a lot of really high mileage rx8s. highest i've seen so far was 186k. engine was still strong.

im at 60k, motor is still strong. maybe 3 dozen drag runs. a dozen autocross runs. and 2 track events. one of which was a 2 day event.

biggest killer of rotaries is driving like a granny. hitting the daily redline clears out excess carbon and prevents it from building up. so all those people who "never abuse the car and always shift under 3k rpm" are killing their engines. i really dont think hitting the redline once a day is such a deal killer.

M20 stroker (2.8-3.0L) with a Racing Dynamics 24v head < all.
