gp90se Posted October 1, 2003 Report Share Posted October 1, 2003 Im looking into another engine since mine went up in flames. theres a 3400 for sale and I was wondering if I used my 4t60 (not e) with a pre obd II (93-95) wiring harness, would it plug into my stock firewall plug and engine mounts? -Jeff Quote Link to comment Share on other sites More sharing options...

However, it probably won't be a straight pull into the firewall. To change that, convert the 3400 SFI to use MPFI from a 3.1L ECM and injectors. It's been done, many of the Beretta guys are getting away with it. - Erik Quote Link to comment Share on other sites More sharing options...
patgizz Posted October 3, 2003 Report Share Posted October 3, 2003 93-95 ecm/harness isnt gonna work as it has the tranny controls for the e trans. i'd stick with a 90 harness to be dead sure all your stuff works first time around(dic, gauges) and swap harness/sensors/injectors over to the 3400. saw a cavalier like that the other day, was an 88ish with a 3400 using the stock 2.8 harness and 5 speed.
