From ashes

[Trogdor]

As many of you know I blew a rod. It wasn't covered under warranty as they claimed it was a result of an over rev stored on the ACD. So, my choices were spend about 8.5 (including install) to have Mitsu install a new stock motor. Or, as I've decided, for just a little bit more I could have built 2.0.

I have things priced out, but I wanted to get some opinions on things where I had multiple options.

-Rebuild: Stock block/crank, wiseco 9 pistons, and MAP x beam from map. I can get the gaskets, oil pan, and oil pump at work for cheaper.

-Fuel: DW65 pump. FIC 1100's or MAP 1000's for injectors? Going E85.

-Exhaust: MAP Downpipe and Testpipe, with my existing Magnaflw cat-back.

-Turbo: Sheides has his BBX that he's looking to sell, that or looking to get an EF2. Your thoughts? I know the BBX will be capable of more power, but I'm really looking to cap out at 450, which is where the EF2 gets me. My concern is about what happens with long term maxing out of the EF2 vs. going with something that I won't be pushing the limits of.

-Clutch: Exedy stage 1 or ACT stage 1?

-Boost: Can someone please explain to me the big differences between and Grimmspeed MBCS and a 3 port?

Also any thoughts as a whole too would be appreciated.

Easiest way around the EF2 issue, EF3. :)

To make 450awhp on my or Ron's dyno you will need bigger injectors and probably more fuel pump, you could do it on a Dynojet AWD though. Maybe a better clutch.

There is MBC and EBCS. MBC is a manual boost controller. EBCS is an electronic boost solenoid. The Grimmspeed EBCS is a 3-port.

How big to I need to go on the injectors and pump do you think?

LOL you are the only person I have ever heard use the term "blew a rod".

I say EF2, Walbro 400, ACT 6 puck, hybrid 3 port/MBC boost control.

Can someone explain the benefits of Manual vs Electronic boost control?

As much as I'd love to sell you my BBX your fuel system listed isn't going to cut it unless you only run it at ~22psi or something. You will need either a larger fuel pump or a BAP, maybe both. I ran a DW300 w/ BAP and FIC 1680's and it was a dandy setup with the BBX...now that the Walbro400 (E85 version) is out I'd honestly slap one of those in with a boomba rail & fuel pressure gauge and see how far it took me on stock voltage/stock feed line.

MBC is a ball and spring, reactive boost control setup. A BCS will release a pre-programmed amount duty-cycle (based on RPM and TPS) and if boost is not hitting target thresholds it will add/subtract duty-cycle. In general, a MBC will boost to a certain boost psi and then taper down a few by redline and a BCS can be programmed for a nice flat boost curve from boost onset all the way to redline.

450+ Dynojet would be easy with an EF2 on E85, 500 would even be possible with the right setup.
