I replaced a blown turbo gasket, and in doing so, refitted the flange with sufficient hardware such that the flange bolts cannot back out.

While I was at it, I fitted a Tomei windage tray and crank scraper. Be advised the scraper feature is useless without user intervention.

Doing some tweaking, I discovered that I can roll right past MBT at high rpm without knock, despite throwing almost 40psi at it with 93 octane. I've made an adjustment to the cam timing to remove a bit of overlap, and I'm going to have to do some careful road tuning to finalize the 93 octane mapping before I swap over to E85.

 

what hardware did you use?

 

If you can reach MBT with 93octance, will you get horsepower gains with E85? i thought that was the whole point of E85, more timing.

I love how effective that water injection is

 

I used:

- High grade socket screws in 35 or 40mm length (can't recall)

- SS serrated face Belleville Washers (McMaster)

- Copper exhaust manifold nuts

 

This is without the water injection activated. With WI, even an occasional midrange 1-count goes to zero. My plan is to tune to the edge without it, then activate it as a buffer.

If MBT can be reached on 93, there doesn't seem much point in going to E85 except as a more forgiving fuel. Anyway, it appears as though this is the case, but I need more tuning time to be certain.

 

arg i still wanna know how you've done it! seems like magic

With E85 my tuner found that a GT3582R T3 TS on a SR20 spooled up 300rpm faster too. I wonder if that will be the case with your setup?

 

Can you go into detail on the install, as I have the Tomei unit and plan on installing it on my stock 2.0L this spring.

 

Same here, ~250rpm.


I'll do a writeup - have photos. Basically, you will need to bend each scraper tab until it virtuallly touches the crank counterweight at the point of minimum clearance. You'll need to get under the car and rotate the crank by hand to get each tab set in the best possible position. If you don't do this, the scraper will be useless.

 

Thanks, I'll be looking for the write-up.
