VR6Will 0 Posted April 6, 2006 I've read recently people have been converting their corrado 2.9 odb1 engines to the later odb2 from the 2.8, what gains are had from doing this? i know the later 2.8 odb2 engines had 190bhp, the same as the 2.9 odb1, so what would be seen from a 2.9 with odb2? i know that the maf, ecu, loom, throttle body & inlet need to be change along with a few other parts, what else needs to be considered?

chrishill 0 Posted April 6, 2006 from what I gather, in simple terms, the ECU is better. I'm sure kev, trigger or one of the other ODB2 practitioners will be able to tell you more in detail. Quote Share this post Link to post Share on other sites
Trig 0 Posted April 6, 2006 what gains are had from doing this? I'll let you know on Sunday.. :) Mine is being converted as we speak so I can't give you a first had opinion on how it's different TBH. Kev is the man to speak to, he's had OBD2 for a few months now and is still loving it AFAIK. From what Kev has told me I will be expecting my torque curve to peak lower down the rev range which is good. Also I know OBD2 has much less tendency to stall and is more economical. Like you say 2.8 OBD2's put out about 190 so I am hoping for a bit more power than standard as well. Basically it is more modern way of engine management and therefore better! Parts required are... OBD2, TB MAF Inlet manifold Engine Loom (Complete!) & Harness Lambda Probe Key, coil read & immob. transponder box ECU The big cost in doing it is the labour though! :) Check P34 on the Supercharged VR6 Thread.
