The "short" of the long story:

Originally I wanted to do a BR 2.3RPM w/ a 6266 build on E85/98. Unfortunately buying in bulk, or even finding E85/98 where I live isn't a reality. $7.00+ per gallon by mail order equally sucks. So, I went back to the drawing board.

After having a rather long discussion with Emery, I've chosen to stay with a 2.0L w/ a 6266. "Reliability" and RPM range played a big part in that decision. I'm confident that it's the right choice. However, I haven't personally done any Pump Gas builds on any DSM before.

For those who are wondering, or will ask what my goals are, the car is mainly used for pleasure. The only time it'll really see any "hard" use is on the occasional Highway On-Ramp, or
Highway in general. I'd like to be able to click off a decent Trap/ET at Pacific Int. and still be able to cruise down I-5 on those sunny summer weekends. The build is just for fun, it's not purpose built, per say, but I would enjoy beating the Lambo's and Ferrari's around here. *cheers*

I was curious if any of my fellow EvoM bro's/broette's that have done a 2.0L Pump Gas build could post their results, as well as experiences with said build:

Your Build:

1) 92 or 93 Octane?
2) Compression Ratio?
3) 4340, 300 M, or AL Rods?
4) Turbo?
5) Engine Management?
6) Timing?
7) Head Port/Polish?
8) Cams?
9) Any Spray (IE: N20, Meth, Ext.)?
10) Dyno WHP/TQ?
11) 1/8 OR 1/4 Trap & ET?

And finally your experience with your build:

1) Any issues with the limitations of Pump Gas?
2) How many miles does the motor have on it after the build?
3) What are the Pros (as you see them, with this build)
4) What are the Cons (as you see them, with this build)
5) Did you change anything after your original build (IE: upgraded your Turbo, Ext.)?
6) If you did it all over, would you do it again? Or would you change something?

I tried to make the questions as easy as possible to copy and paste, so hopefully it's easier on those who are willing to share their builds and experiences with me.

Thanks in advance guys/ladies. Any help is much appreciated.

 

I'll give you my .02 but I do have an E85 2.2 on a small turbocharger

Your Build:

1) 92 or 93 Octane? E85
2) Compression Ratio? 10:1 , I would go 9:1 for pump gas
3) 4340, 300 M, or AL Rods? Carrillo H beam with bolt upgrade
4) Turbo? FP Red HTA with twin scroll
5) Engine Management? AEM Infinity tuned by Jay Meagher
6) Timing? 2.5@ 3800ish to 13.5@8000
7) Head Port/Polish? Headgames "pocket port"
8) Cams? S2
9) Any Spray (IE: N20, Meth, Ext.)? Nope
10) Dyno WHP/TQ? 613whp/504tq Dynojet
11) 1/8 OR 1/4 Trap & ET? 11.3@128 Rolling out at 4000rpm no boost

And finally your experience with your build:

1) Any issues with the limitations of Pump Gas? I don't run it hard on pump gas since its high compression and E85 is close enough.
2) How many miles does the motor have on it after the build? 4000ish and climbing
3) What are the Pros (as you see them, with this build) Stronger rods , displacement and compression help with drive ability with the 4.11 final drive
4) What are the Cons (as you see them, with this build) Cost
5) Did you change anything after your original build (IE: upgraded your Turbo, Ext.)? No
6) If you did it all over, would you do it again? Or would you change something? I would run 9:1 compression since my base wastegate pressure is 24lbs now. I've never run things hard on pump gas but it would be nice to run 20lbs on pump if I needed to take a long trip.

I would recommend a nice strong light rod like the carrillo. Its easier on the bearings . I'm also a fan of CP and wiseco pistons with a compression height at 1.134 or more. Also, a .230 wall or .250 pin if its going to make over 600whp. Its cheap insurance .

Having gotten 80+k out of my last 2.4 block at the 650awhp level, I'm pretty confident about the big block's longevity. From your description, you really do want a 2.4 - the low end torque difference is very dramatic.


1) 92 or 93 Octane? 92
2) Compression Ratio? 9.0:1
3) 4340, 300 M, or AL Rods? R&R long steel rods
4) Turbo? pte 6266gen2 in a 1.15 divided T4 turbine housing
5) Engine Management? oem ecu
6) Timing? enough to get the job done.
7) Head Port/Polish? yes, fully ported head
8) Cams? GSC R2
9) Any Spray (IE: N20, Meth, Ext.)? none
10) Dyno WHP/TQ? 605/458
11) 1/8 OR 1/4 Trap & ET? none yet

And finally your experience with your build:

1) Any issues with the limitations of Pump Gas? keep backpressure to a minimum
2) How many miles does the motor have on it after the build? 2000+
3) What are the Pros (as you see them, with this build) gobs of torque under the curve
4) What are the Cons (as you see them, with this build) rev limited (Long Rod 2.4)
5) Did you change anything after your original build (IE: upgraded your Turbo, Ext.)? nothing
6) If you did it all over, would you do it again? Or would you change something? Already did it again - My last build was a std rod 2.4 on an fpBlack. I changed from the Black to an ETS divided T4 kit to help with the fpBlack backpressure challenges.


Love this combination, tame enough to commute in the i405 bump and grind, and monster enough to spank just about anything that rolls up on me.


and if that isn't good enough a switch to e85 nets me 734/552
