Exactly what consists a high revving build? Namely the block...

Keeping my block a 2.0L and I bought Manley TT rods, .020" over AMS/Ross pistons, new stock crankshaft, and Clevite 77 bearings and I wanted to know if I'd be able to hit at least 10k RPM with this setup. I wouldn't be shifting there all the time (more like 8.5k) but I just wanted to have the option if I wanted to when I go big turbo.

I know aluminium rods are an option for the high revving builds but does anybody know how well my setup will hold?

Thanks in advance...

If you went long rod 2.0l and invested 5k in a dry sump than yes. If not Id love to watch the video of you reving to 10k for more than a split sec under no load.

Wow! How helpful!

I believe that Kouzman has a thread about reving to 10K. Revving that high is big turbo territory. Unless you want to trap 150+ there is no need.

Sorry, your going to need a lot more $$ for 10k RPM. You wouldn't want to rev it that high anyway it will accelerate engine wear greatly.

Only two useful posts...thanks guys. Like I said, definitely wouldn't be really revving that high ever but I just wanted to know if it was possible.

I found the video kouzman made in this thread...https://www.evolutionm.net/forums/ev...6-9000rpm.html

He used acl bearing and lightweight everything. In the thread he gives a basic mod list. He also still only revved out to 9K. I used to be intrested in revving to 10K. It seems that you need deep pockets. People change there bearings out frequently.

I am now looking for something reliable as possible while still making good power. I plan to go 2.0L or 2.1L. I am hoping that building an engine that with a good r/s ratio, a lightweight rotating assembly, an upgraded oil pan, and possibly a crank scraper. Will help create a long lasting engine. I figure I still need to replace bearings regularly though.

i'm pretty sure the stock cranks dont like that kind of rev's.
You need special oiling properties of high end aftermarket cranks.
Not to mention oil pump at that rpm.

It is possible.
DS9 (STM NZ built evo9) ran up to 11,000rpm, but with a full billet crank and ally rods.
But the engine was very well built, and i'm sure was pulled down often to check for wear.

OEM crank isn't straight shot oiling... dont think the bearings will be very happy at that rpm

Good info guys...looks like I'll play it safe and keep it under 9k.

Thanks a ton!
