+20HP?
+20HP?
Can I gain 20 HP without a turbo upgrade? If so, how? What real consequences will there be to modding? If you can reply with your experiences and/or links etc. Much appreciated!
Lastly, despite running really well, after I drive it for more than 20 mins (mixed, highway doesn't matter) it seems to have a little less spunk, not awful, no missing, coughing, still smooth, just a little "flat". What can I check on? ALDA port is clear. No documentation that turbo has ever been replaced/rebuilt. Vacuum pump has been replaced. Down pipe replaced. Fuel tank and lines replaced. Regular LOF etc. I have 120K on it now.
Thanks for any help or direction!

08-08-2014, 04:55 PM #1I found and bought a 92 300D 2.5 OM602 this last spring. 117K well documented miles. Fully stock. Runs well. I want to add ~20HP? to essentially compensate for A/C compressor when I have the A/C on (road trips) and have a little extra seat of the pants feel.

you will overboost engine beyond safe limit. This turbo can make 27 psi so be aware. While driving
I seldom allow boot to come to about 20 and let go gas. While cruising I am aiming to maintain about 2 psi or less. Did I gain any hp? I don't know. But I can tell you car feels very responsive.
1977 300D for parts? Just a pile of rust but still runs!
1984 190D 2.2 - gone to better home
1987 Dodge Maxivan with OM603 and Goran’s 7.5 backroads terror
1987 300TD - tinker toy
1989 300TE - parts
1991 300TE - backyards decor
1991 300TD - Barrote’s 7.5
1992 300TD - semi-STD(Goran modified 7.5 ip but still with factory turbo+at)
1998 E300TD - dd with DSL1 now
1998 ML320 - snow ride
2014 Sprinter 2500 - Malone’s tune + pedal box
With just a turning up pump by two turns ( as discribed in increasing maximum fuel) and advancing timing to 20-21 deg. adjusted at idle you will gain some power and torque. Factory turbo will handle extra fueling with no problem and car will be more lively. Boost gauge a must because if you booted
