IfinishB4u Posted November 15, 2003 Report Posted November 15, 2003 Hi, I am new here but have been on clubgp for a while, although you guys seem to have more 3.4 owners over here so I thought you might be able to help a little more. I have a '95 GP SE with the 3100 and When I blew the intake gasket at 167k, I also spun 2 rod bearings. and the sludge of oil/coolant is everywhere in the motor. I was able to get my hands on a perfect RUNNING condition '92 cutlass 4-door with the 3.4 DOHC with 91k miles for only $200. I was wondering how difficult it is going to be to do this engine swap. Do I need to worry about putting my tranny on the older motor or does the '92 cutty have the 4t-60e? Also how about motor mounts, and wiring harnesses? Thank you very mch in advance, and I will be hanging around the board quite a bit now. -Nick- Quote
topless94style Posted November 15, 2003 Report Posted November 15, 2003 You will need the harness and computer from the LQ1 im pretty sure on that one. the 92 should have the 4t60e, but i think you will still need the harness from the LQ1? I am guessing new motor mounts and the dogbone for the LQ1 also. I have gained all this info from this site, if I am wrong correct me. please. Quote
Redfox340 Posted November 15, 2003 Report Posted November 15, 2003 IfinishB4u, welcome! An OBDI DOHC swap from a OBDII 3100 SFI is going to be a bit more chanelleging since you're reversing the process. However, if you're determined, you'll need to swap the entire powertrain (engine / tranny). Along with all the ECM and the donor wiring from the DOHC; you'll need to integrate it into your existing components. Also, you still may need to swap out the entire sub-frame; that's something to do research on. Do-able? Yes. Practicle? Probably not. You may have better chances getting the DOHC running in better status in the Cutlass. Just my personal input; take on what you can do! - Erik Quote
Dannymik Posted November 15, 2003 Report Posted November 15, 2003 Welcome to the board, boy have you started out with a bang! Would the 3400 be easier to swap for a 3100 vs the 3.4? Quote
godofthunder Posted November 15, 2003 Report Posted November 15, 2003 yes....it would, as i have heard. I personally plan to take that route when this engine goes....rather than the DOHC or the boat L67. While i want the 3.8 s/c...it just seems like to much work, and id rather just buy the dang GTP jon Quote
