Shifter23 Posted December 8, 2011 Report Share Posted December 8, 2011 Just figured I would ask the main differences of the two set-ups and what could be done to use a later unit with SFI in a Multiport car. Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted December 8, 2011 Report Share Posted December 8, 2011 if you're asking the difference between a 3.4 DOHC and a 3400, well, they're completely different and basically nothing will work. Quote Link to comment Share on other sites More sharing options...
GOT2B GM Posted December 8, 2011 Report Share Posted December 8, 2011 I think he's talking putting a 94+ LQ1 in a 91-93 LQ1 car, but correct me if I'm wrong. Quote Link to comment Share on other sites More sharing options...
Shifter23 Posted December 8, 2011 Author Report Share Posted December 8, 2011 You are right on the money GOT2B GM. If I was so lost that I didn't know the difference between a standard 3400 SFI and a LQ1 I probably shouldn't be dealing with ten TGPs The reason why I was curious is the factor I may be adding a 91 GTP 5-speed to the collection and I found a low mileage 94 LQ1 out of a GT for cheap. I was debating on picking it up for a spare around the shop since my 93 Cutlass convert is long gone. Quote Link to comment Share on other sites More sharing options...

slick Posted December 8, 2011 Report Share Posted December 8, 2011 Let's see... You wont use the cam sensor on the front valve cover, and maybe one or two other sensors/plugs are different, but thats about it. Been years since I've had my (z34 (swapped and lots of mods), but the list isn't long and its very doable. Quote Link to comment Share on other sites More sharing options...

Shifter23 Posted December 10, 2011 Author Report Share Posted December 10, 2011 That is good to know. I did pick up the 91 GTP and am pretty stoked to have a manual w-body added to my set. I will be getting in touch with the other guy and pick up that motor before someone else does. Quote Link to comment Share on other sites More sharing options...

Shifter23 Posted December 12, 2011 Author Report Share Posted December 12, 2011 Yep you could say I am a little out there when it comes to cars. But I will say at least half of the w-bodys I have picked up were not going anywhere nice so at least I saved them from the crusher. I did for a while there have a complete collection with a white TSTE but I had to sell that earlier this year. But I probably will pick one up again lol.

Z34guy Posted December 12, 2011 Report Share Posted December 12, 2011 Similar question. Looking at a '96 Z34 parts car for my '95. What would I need to swap over from the 96 besides the engine and PCM? I'd imagine the wiring harness, but I hope I could keep my gauge cluster.

There is actually quite a bit different from 95' to 96'. The whole PCM yes, and all the damn sensors that go with it, will be in the block of the 96'. All the emissions were changed for 1996 as well as the entire top half of the engine. Quote Link to comment Share on other sites More sharing options...

Shifter23 Posted December 13, 2011 Author Report Share Posted December 13, 2011 Pretty much going to a 96 motor there will be some serious retro-fitting. Are you wanting to go to OBD2? Quote Link to comment Share on other sites More sharing options...

I planned on it eventually but not this soon. looking at a parts car and trying to consider any incompatibility issues before even making a decision. Monte has bent valves.

19Cutlass94 Posted December 17, 2011 Report Share Posted December 17, 2011 I always thought Multi-port and SFI was just a difference of the ECM? Yes there were subtle changes in the motor itself between OBD1-OBD2... Quote Link to comment Share on other sites More sharing options...

Yes there were subtle changes in the motor itself between OBD1-OBD2... There other differences besides SFI in 94, but SFI needs a cam sensor and it had different injectors since they are no longer firing twice for each intake valve opening.

Artemis Posted December 19, 2011 Report Share Posted December 19, 2011 I planned on it eventually but not this soon. looking at a parts car and trying to consider any incompatibility issues before even making a decision. Monte has bent valves. I did it this summer, swapped a 96 into my 95. You'll need the entire motor, PCM and harness. There's really only a few changes to the harness to be made. Gauge works fine, everything works fine in fact. Except for DIC, you'll need a 96 DIC. And if you manage to acquire 2 of them I could use one too! If you have any questions, let me know.
