I've been doing some research as far which bottom end to build and I think the time has come to stop trolling through existing posts. I'm building a car that will see a lot of street use and quarter mile abuse but is not my daily driver. Tuning will be done on both 93 and E85. I have a full race twin scroll setup based around an EFR 8374 EWG with a 1.05 A/R (79lbs/min). I just want to say first of all this isn't another post asking for ***** to the wall power and faster than stock spool. I fully understand the capabilities and limitations of this turbo after extensively talking with full race. I was initially debating a 2.1 or a 2.3LR but I don't want to limit myself to any engine. From what I have seen this turbo puts down very good numbers on a 2.0 from ~5500 rpm and up and can only get better with more displacement and/or rpm (I based this on the pump gas results). If I could rev my bottom end to say 9500 well then that's a good power band in my opinion. Alot of motors can rev that high but which ones actually live for a while at those rpms? If anyone has regretted anything about a build like this, what was it? I'm looking for as much info as I can before I decide on a shortblock. What have your experiences been with the motor you have decided to build?

 

4g64 Block
94mm Crank
159mm Rods
Custom Pistons

DONE.

(BTW, this = 2.2L)

 

Easier to read now.

 

I haven't seen much along the lines of a 2.2. Everything seems to be 2.1. Any reputable builders for a 2.2?

 

Blue, what intake manifold and tb u recommend for my build ? I am going with 6266 journal bearing e85 making around 600awhp

 

Talk to English Racing or Fathouse Fabrications and they'll be able to set you up with whatever setup you decide, with ample information in regards to what to go with .

Ran with a Full Blown 70mm TB.

If you don't like that, go with a ported Skunk 2 IM or a Magnus.
