yep stock rods, pistons, crank, bearings, timing gear, valves, springs, lifters, vvel, ports(nothing is ported). the only internal changes were the cams and removing the oil pump.

There was some slow secret sauce poured into the trans to help with the higher rpm shifts tho, eat that TSM lol

With OEM rod-bolts, I'd be reluctant to exceed 8000rpm, but that is just me.

Remember, NASCAR engines run 9500rpm and more for hours and they are all >3-inch stroke.

great thread btw! I was hoping to find something like this. Sry you had to sell.

Did you ever take it to 9k? I saw you mentioned it, I have yet to watch all the videos (thank you for videos!)

and as it was asked before, the stock internals are able to support the higher then 7.5 redline easily. My goal is really just 8k with NA reliably and am starting to look into external oil pumps, as is sounds like the Nismo pump is not enough. Any advice is defiantly appreciated.

All of my cars have been NA engine builds ( 1999 civic hb & 1999 Miata ), I am collecting data for this platform as this v6 thing is new to me.

He ran it that high when I was in the car... it was stupid fast... lol the gears lasted forever! 53mph in first gear!!!

geez, the stock internals don't mind that many rpm's?

Im just curious, since your budget and engine was open why you didn't go for stroker to get the most out of it?

Correct me if I'm wrong, but I always thought that hi rev motors work better with shorter stroke?

So the stock Pistons/rods/crankshaft etc can handle 8800rpm if the rod bolts and oiling system are upgraded? Probably would want to use hr heads as well.

Just got back gonna load up the video latter tonight, really need to adress traction issues. Pulled 2.328 60ft and still trapped 113.1 at 13.3. It has got the power to go deep 12's but i might as well be launching in second with my 60ft times.
