Will you be running a dry sump oiling system or do you plan on making modifications to the factory Oil pump to accommodate 10K+ rpm.

Yes I will be sending the oil pump to Accelerated Performance for a little work

Something came back from California yesterday

89.5 bore, and the ej25 crank right. What compression?!? 13.5:1?!?

I love NA builds (used to have an NA EG back in the day). I didn't read word for word this entire thread ..but I think you're destroking it or decreasing displacement or something, and making it a highly tuned, high rev monster?

Anyways...why not just do a crate LS3 swap? It'll be NA, 400+whp that is oem factory built and reliable and bulletproof. And also similar in weight of a stock FA. I bet it would be a lot cheaper too than getting a custom fully built NA FA engine..not to mention there's going to be countless hours of tuning and troubleshooting afterwards to get that NA FA working at its' best.

FB25, the EJ does not support timing chains and has a smaller stroke larger bore

Increasing stroke and bore.
Why LS3? its been done, too many times. and it raises the center of gravity of the car and handeling

True and true.. never liked the idea of ruining the car's true form and balance/cog either...and also kinda don't like the idea of sticking a domestic engine in it.

So what's the final displacement of your engine after your bore and stroke? 2.5?

Whats your final comp ratio goals? ...I am actually still pretty amazed at the stock FA's CR... I remember in the 90s, a 12.5:1 CR was already considered crazy insane high.

What are your plans with the upper block? ...port&polish heads, cams, valvetrain parts, mill the head and/or block? ..and tune.

Any modified intake manifold tb, or itb's setup?

I wonder if Toda is doing an NA FA engine. Aren't they Japanese NA specialists?

There are a few companies out there working on Valvetrain parts. This particular build is unexplored territory so all kind of unknown at the moment.
As for high compression the DI helps with that.

Any updates?

Keep it up! Sleeved block FTW! Look forward to some nasty high reving action from your build. Best of luck overcoming hurdles and props for blazing the trail.

Herro?

Currently sources of money are being spent on family trips and a trip to SEMA in November. Sorry for the slow build, like Rome it was not done in a day.

Also paid off all existing credit cards
