I run 11:1 compression and 30+ lbs of boost on E85. Put the M54b30 pistons in it with a stock head gasket. A GT35r with a T3 .063 would be okay for what you want. A GT45 is ridiculously too big. Assuming we are talking about actual garrett turbos and not ebay china ones.
That's over 2 bar! Impressive with CR higher then on a stock engine!
.63 would spool fastest, right?
I know that E85 won't knock, but what about EGT? Is it also lower with E85 (don't want to melt the bloody thing)?
Compered to .84? I mean - lower a/r = lower spool?
The E85 brings me back to my original plan. First make a stroker, then Turbo it... How would a Stoker perform on the E85?
yes, lower AR means faster spool. Beware of comparing specs and results on china turbos. Garrett GT35r does not = ebay GT35. I wouldn't bother with converting to E85 until you put the turbo on it, but if you want to get that out of the way go ahead.
Well, as I can turbo o on a stock CR of M54B30 pistons, I can follow my original plan:
1. Do the chassis, brakes etc. and change ECU to standalone,
2. Build a stroker,
3. Turbo it.
As each step requires remapping I was wondering if there are any benefits of E85 on a NA engine. I guess you could go with more aggressive timings, right?
Thanks, so that actually looks like 1-2 mm - guess it's more work to put it together and check if it's ok?
It’s hard to tell in the picture but it’s actually probably double that. I just installed the crank in with old main bearings and one rod/piston without rings to check the clearance.
BTW, is there anything I need to replace specifically for E85 on E36? Like fuel lines, some specific fuel pump? I know that injectors need to be bigger then for pump 98 and that alloys cells don't like it...
