Imp558 Posted December 7, 2017 Report Share Posted December 7, 2017 You can not bolt a second gen subframe into a first gen. You can do an L67 and 4T65 but you need the CV tulips from an HD car and there were different size tulips for different car lines so it should be a second gen W-Body. Wiring to make it run is a hurdle, making the gauges all work is a hurdle. This could have been covered in one thread, like this one: http://www.w-body.com/topic/56149-89-grand-prix-complete-3800-drivetrain-and-powertrain-swap/?do=findComment&comment=1249673 Nas Escobar 1 Quote Link to comment Share on other sites More sharing options...

Suspension becomes a headache though... 90sEraWhips 1 Quote Link to comment Share on other sites More sharing options...
Imp558 Posted December 8, 2017 Report Share Posted December 8, 2017 The consensus was that the front subframe bushing mounts were a different distance apart but the rear ones were the same. Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted December 8, 2017 Report Share Posted December 8, 2017 Do you have pictures of the 2G cradle in a 1G? To OP: The L67 swap has been done no less than 59,493 times. Google is certainly your friend here. Short answer, you need to play a lot of GM legos and start with a W-car 3800 (to make it easiest).

Imp558 Posted December 8, 2017 Report Share Posted December 8, 2017 I'll be damned, Miko said his bolted right up. http://www.w-body.com/topic/30787-widebody-t72-turbocharged-3800-cutlass/page-15 Quote Link to comment Share on other sites More sharing options...
Nas Escobar Posted December 8, 2017 Report Share Posted December 8, 2017 Gen1 control arms are bolted to the K frame, and our struts are martian. Swapping the Gen2 frame, doesn't that mean that the whole suspension has to be reworked? I remember Miko's car... that thing was all modded up. 90sEraWhips 1 Quote Link to comment Share on other sites More sharing options...
Imp558 Posted December 8, 2017 Report Share Posted December 8, 2017 I'm going the other way, first gen subframe and second gen everything else. Quote Link to comment Share on other sites More sharing options...

Bake82 Posted December 13, 2017 Report Share Posted December 13, 2017 Yes can be done. -3800 motor and trans from a w-body(mounts are different between the different chassis. Just makes it easier). -Inner tulip cv joint from Same trans out axle from 1g w -Wiring harness 98-99 Monte Carlo/lumina ltz, need to mod c100 conector but easy enough -downpipe from same monte/lumina -power steering lines from monte/lumina -heater core lines from Monte/lumina -rad and hoses from 3800 carMotor will drop right into the subframe and into the car no issues.You can use the 2g wiring but you're into more wiring of the c100 connector as they're completely different. 90sEraWhips 1 Quote Link to comment Share on other sites More sharing options...
l67ss Posted December 13, 2017 Report Share Posted December 13, 2017 On heater hoses use the ones that match the yr of the alt bracket. Bake82 1 Quote Link to comment Share on other sites More sharing options...
