Guest Anonymous Posted January 11, 2005 Report Share Posted January 11, 2005 Would a 3400 DIRECTLY swap in place of an existing 3.4? If not, what needs to change? would it still work with my gadgets? Quote Link to comment Share on other sites More sharing options...

gp90se Posted January 11, 2005 Report Share Posted January 11, 2005 things that would need to be changed: wiring = yes pcm = yes engine cradle= no the firewall plug on the 3x00 and the 3.4 harness are the same, so is the cradle. still think the 3.4 is a much more fun motor Quote Link to comment Share on other sites More sharing options...

White93z34 Posted January 11, 2005 Report Share Posted January 11, 2005 good luck finding a shop to swap it though. most shops won't be bothered with indirect swaps. i'd say do it yourself. but we all know how that goes. Quote Link to comment Share on other sites More sharing options...
patgizz Posted January 11, 2005 Report Share Posted January 11, 2005 cradle = same. 3x00 and 3.1 use same mounts. wiring = compatible except for injector plugs. i've used the same harness on my original 3.1, my first swap the 3.4 dohc, and now my '00 3400 swap. couple things need moved around but it works fine. need p/s lines and radiator hoses off a 3x00 w-body, as well as an exhaust downpipe off a 3x00 w-body. as far as the computer goes as of today mine is running freaking sweet on a 93 3.1 chip and 3.1 injectors, until such time as i get it out to ben for tuning with bigger injectors. all 3, same harness, 3400 and 3.4 used the same 4T60-e(till such time as i get around to putting in my hm-282). you'll need to find a 93 3.1/automatic chip for your car to keep controlling your electronic trans, if you want to go that route. FYI it ran like ass with the dohc chip and injectors, and ran like ass with dohc injectors and 3.1 chip. but the 3.1 chip and matching injectors are tits.

Guest Anonymous Posted January 11, 2005 Report Share Posted January 11, 2005 You people are vultures. Anyway, were there other cars besides w-body's that had a 3400, and are the parts compabable? Quote Link to comment Share on other sites More sharing options...
JoroCorona Posted January 25, 2005 Report Share Posted January 25, 2005 The 3400 was in the Aztec and Venture/Transport lines. Aswell as the obvious W-Bodies, Impala and Monte Carlo... I'm not sure if they ever got into GPs. Quote Link to comment Share on other sites More sharing options...
Canada Posted January 25, 2005 Report Share Posted January 25, 2005 Yep...........base GPs anyways. You've got the entire U, N, and W line up to choose from. Quote Link to comment Share on other sites More sharing options...
BIGBULS Posted January 25, 2005 Report Share Posted January 25, 2005 Yep...........base GPs anyways. You've got the entire U, N, and W line up to choose from. Base GP's and "base" Regals (Century in other words) got the 3100 (big port from 00-03)............NOT the 3400. Canada = duuuuuuh........

Prospeeder Posted January 26, 2005 Report Share Posted January 26, 2005 Grand ams had the 3400, SE1 and SE2 and GT's wich had a ram air version with more power, not much though, pretty bad setup. WHy is a 3400 better than the 3.4? less power w/ the 3400, even though the 3.4 has reliablilty issues, the 3400 has Intake manifold gaskets and water pump problems too. Why do such a swap?

cryptnix Posted January 30, 2005 Report Share Posted January 30, 2005 oh and http://www.3400swap.com/ uhh whats that? also for the 3400 ... there are new gaskets out that take care of it. Quote Link to comment Share on other sites More sharing options...
Canada Posted January 30, 2005 Report Share Posted January 30, 2005 I guess I really haven't ran into many maintence issues with the LQ1.....it could pry go for a timing belt. But like thats hard to do. The LA1 in the Beretta isn't a bad motor either.....in fact.....it pulls on my Grand Prix quite nicely from certain speeds....even though it lacks top end and is teamed to an automatic transmission with a weak dick torque converter.
