Thread: Project 11 (M90 All Out)

Keeping my fingers and toes crossed for you bro that you don't have the dreaded 100 mile motor! So far, it looks awesome!

Ati balancer might be some added insurance but I think the crank was already balanced with the stock dampner?

Yeah. I did everything I possibly could do (in terms of machine work). I really just wanna build a racing block that can handle all things M90 (with the exception of excessive kr obviously). Steve at Thorsens really helped walk me thru all the trouble spots and schooled me on how to do it right. He's expensive , but his track record is what makes up the difference. If there is any misshaps, It would be because of a mistake I made in reassembly.

After Steve looked at it, he suggested that I don't micro polish. He sid the crank looked perfect on all the journals. And that it wouldn't get much better than what I had. Now this was , of cours, after I wrote the mods in the thread. I was skeptical, but now that you mentioned it, I'm glad I listened!

First Startup was today. Didn't take it out because I'm looking at an injector pulse issue before I give it revs. Don't need anything that would risk a good AFR before I learn the limits of the car. So basically, I have to drive the hell out of it just once. I wouldn't advise my type of driving for anyone when I have to "relearn" my car".

If I don't, it would mean an almost for sure accident if I ever have to make a fast decision while driving hard. Half of the suspension is different in this new shell. But in the short time I've had it, it's been a blast. Just gotta get used to the extra power in the revs and a much different power curve with the 3X instead of the XP.

Video footage of my "relearning" being considered.

Do it.

I want to see this.

Plus you have a nice camera so it'll be worth it.

Probably. Only reason I won't run them on the street is because of the benefits of the roller tip for the entire valvetrain. Scott knows his stuff and I'm sure the stock rockers will make a few more ponies, but I'd only install them at the track or on the dyno to compare. I drive on the street a lot and I'm still investigating a lot of alleged issues regarding stock rockers and valve tip wear on heavy builds.

Thank you!

If I would have figured out the injector issue, it would have been 7 weeks from start to finish.

No pulse. The only way I can start the car is by pouring e85 in the injector ports. It runs for a few seconds until the fuel burns off. Very annoying. I've got good pressure at the rails. The fuel pump is good. All fuses are good. Crank and cam sensors are good. All the grounds are good, the coils are firing. No vac leaks. Just an annoying injector issue where none of them want to fire.

Might be of some help.

Matt. I love you! (In a very heterosexual way) I will be putting that link to use when I get back in town after Christmas. Thanks buddy!

Yeah, he "loves" you alright.

so where abouts in mi are you? If i'm not mistaken your around flint right? I could use a guy who knows wtf they are doing if you ever wanted to make a extra $$$ on the side to help me out.

very nice project by the way. Can't wait to see this thing running. Good luck
