are you guys saying to put 2.2 heads on 2.5D?

I think i have sold the P0106 code by installing a front canister and plugging the hose from the T. The torque question is still bothers me. I do believe the casing of the engines and trans are same size. The TC on 2.2 is smaller and has a different stall speed. Theoretically one should be able to install a 2.2 TC on to a 2.5 trans and drive it. I would like to test it on a dyno and see what would it do. But don't have the dyno. Turning the smaller diameter will increase the torque. I will visit a local factory in town and see if they will let me play with a dyno. A wish... but one never knows... maybe they will. :-)

Hey Rooster. My 2.2 has an EGR. But looks like i have licked that code. I did pull the front canister from the donor car and also the vacuum switch from the right strut tower. The Map can stay the same. All the hoses plug in. If you look at the vacuum diagrams you can figure out how the hoses go. no 1143 fro three days now.. :-) but P0106 came up yesterday. have to deal with that now. Here is another thought. During the swap, we were told to leave the Torque converter from 2.5 and keep the flex plate from 2.5. I wonder if anyone has tried to mover the 2.2 torque converter with flex plate in the OB. Turning a smaller diameter will increase torque . the torque converter should fit.

Sorry it is not an P1156 it is 1143 undocumented code and EGR flow code showed up... i wonder why?

Well. the car drives fine. a do get the Check engine light coming on every few days or so. P1156 undocumented code. something to do with MAF :-(

BTW, the sensor was bad. easy enough to test . Just have another set of eyes with ignition on inside the car monitoring the speedo needle. Unplug the sensor and plug in the working sensor . Then rotate the sensor with your fingers. If needle moves... the comp and cluster OK. Lucky i had a used sensor in the tool box. :-)

what advantage to that? i heard of 2.2 heads on the 2.5D block but not the other way around

checked before work this morning... the sensor is plugged in. will look this evening

Well.., the swap went uneventful. Everything bolted on like it should. Took me 6 hrs by my self. Took it for a drive.. and Speedometer is not moving. GOt a code for a speed sensor A. TO late to look at it. The most important thing is. The power loss is negligible. 98 OBW with 2.2 is a definite winner. Want to go faster?... press harder on a pedal. No more ej25D for me. Not worth it. I would rather build a Frankenstein. Pj yeah.. the airbag light is on... and it is a manual read? Sucks!!!!!!!!!!!!

now that is a confidant answers. Then 2.2 it is :-) Thank YOU gentlemen

The thr4ad on top is a good read... told you i am blind.. :-)

I have read about it. That thread did not address the comparability after the swap. I have several 95 ej22 ready to go instead of ej25D. I have built a few ej22s for experimental aircraft use. There are many of these little engines flying in rotor craft and airplanes. I just wondered, since the OBW is a bit heavier then the L wagon and has the larger diameter tires, how much of a difference people that have done the swap do see. But i will trust your opinion and install a 2.2 in to 98 OBW with 132K on it. But i do appreciate everyone's response on this matter. Thanks.

Hi Guys, First time writing here but been reading for a while. There has been many threads on a swap of EJ25D for Ej22. I might have missed it, But i really did not see any feedback on performance of the OBW with 2.2. Is it worth to lose 20 HP on a swap. How much difference is there with 3 people? If there is a write up on this please point me toward it. Thanks.
