AWeb80 Posted March 4, 2010 Report Share Posted March 4, 2010 I know this is a noobish question, but I'm posting from my phone cause i have no int reception on my comp so looking up indepth info is hard. I know I need the U/L intakes and TB.... I'll get all this fromm a 00+ car. I also need a coolant hose I think. Someone list it please. I may finally be able to head to the JY friday to get this crap I've been wanting for months.....Ken failed me. Quote Link to comment Share on other sites More sharing options...
Jonpro03 Posted March 4, 2010 Report Share Posted March 4, 2010 egr delete from wot tech. You have to loose the alternator bracket that runs from uim. Keep the same fuel rail/injectors from your old setup. Quote Link to comment Share on other sites More sharing options...
AWeb80 Posted March 4, 2010 Author Report Share Posted March 4, 2010 I dont want an egr delete...I don't want a ses light on. I can make an adapter myself. aren't there two styles of egrs though? Quote Link to comment Share on other sites More sharing options...

Jonpro03 Posted March 4, 2010 Report Share Posted March 4, 2010 The egr on the large port has the same harness connector and it does work If it helps, heres pics from my lg8 swap: Also, make sure you get a 56mm tb to go with it. The LG8 i got had the 52mm so I got a 56mm off of a minivan in a j/y and swapped over the throttle assembly: Quote Link to comment Share on other sites More sharing options...
slick Posted March 4, 2010 Report Share Posted March 4, 2010 While you are there, you should find yourself an OBD 2 harness and PCM! Quote Link to comment Share on other sites More sharing options...
BXX Posted March 4, 2010 Report Share Posted March 4, 2010 Exactly what slick said. Stock smallport 3100 injectors will be running damn near static with the 3400 UIM/LIM setup. Get a set of L36 injectors, swap in (direct), and you will need to retune the PCM for this (just change the injector flow rate table) Our stock injectors are 17lb/hr which does indeed max out at around 160hp.

94GPGTP Posted March 4, 2010 Report Share Posted March 4, 2010 Adam its easier than you think to go OBD 2.. I have a complete engine bay harness and a computer along with the computer box i can sell you if needed.. I also have DHP Programmer to modify your computer and get the maximum out of that thing.. You dont need to run the 2nd O2 because you can turn that off in the DHP you just need to add i believe 2 wires to the interior of the car and done.. You will have dam near all the components unpluggged when you go to top swap your engine.. Why not spent another hour and swap out your harness.. Oh and you need 2 OBD 2 knock sensors and i have them if needed too.. You can also delete the EGR in DHP and just block it off completely.. You will never get a SES.. Think about going OBD 2 your already going to have your car apart.. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted March 4, 2010 Report Share Posted March 4, 2010 Our stock injectors are 17lb/hr which does indeed max out at around 160hp. 17? it's not a 3.1, it's a 3100, should be 19lb/hr... and this should verify everything: http://wot-tech.com/shop/articles/94-99-3100-large-port-swap/cat_73.html Quote Link to comment Share on other sites More sharing options...
AWeb80 Posted March 4, 2010 Author Report Share Posted March 4, 2010 how do i add the to knock sensors? this is sounding a bit more fun. i'd love to tune the car. i know in stock form, the AFR's are pig rich above 3k rpm. Quote Link to comment Share on other sites More sharing options...

Jonpro03 Posted March 4, 2010 Report Share Posted March 4, 2010 The knock sensors I don't know about, but I know if you do go obd2, get a maf sensor with your harness and like Robert said, you can just turn off the second o2. Do you know if you have roller rockers? Are you gonna do an obd2 swap? Quote Link to comment Share on other sites More sharing options...
AWeb80 Posted March 4, 2010 Author Report Share Posted March 4, 2010 i need more info on how involved it is Quote Link to comment Share on other sites More sharing options...
Jonpro03 Posted March 4, 2010 Report Share Posted March 4, 2010 This should give you a good idea of whats involved. Here's a similar swap to what you're doing except on a beretta. http://bstuff.com/index.php?showtopic=47614 I gave it a brief read-through and it looks like theres a lot of wiring under the dash to make the obd1.5 port an obd2 port. Which you need if you're going to tune. Quote Link to comment Share on other sites More sharing options...

Jonpro03 Posted March 4, 2010 Report Share Posted March 4, 2010 Back to the intake swap... Adam, do you know if you have roller rockers? If you have stamped steel they wont clear your new large port intakes. Quote Link to comment Share on other sites More sharing options...
AWeb80 Posted March 4, 2010 Author Report Share Posted March 4, 2010 they will if i grind the intake to fit. many people have. Quote Link to comment Share on other sites More sharing options...
cubsfan24 Posted March 4, 2010 Report Share Posted March 4, 2010 Sorry to hijack the thread but I have been thinking about doing a top swap on my 96 3100 since I think my LIM might be starting to leak a little. So the best upper intake manifolds to get are from 2000+ 3100's or are the 2000+3400's better? So if I go with 2000+, I will need a new EGR valve, new pressed in coolant return hose, new UIM/LIM gaskets from the donor engine year, and a 3400 56mm throttle body.

BXX Posted March 5, 2010 Report Share Posted March 5, 2010 http://www.w-body.com/forum/index.php?topic=83173.0 Thank you chris. Adam, OBD2 is less work than the largeport swap. Trust me, ive done both. If you need sensors and parts and such, I will be hittin up pullapart really soon, I will get some for you. If I see a harness I will pull that too since they are so cheap. Our stock injectors are 17lb/hr which does indeed max out at around 160hp. 17? it's not a 3.1, it's a 3100, should be 19lb/hr... and this should verify everything: http://wot-tech.com/shop/articles/94-99-3100-large-port-swap/cat_73.html Its 17lb/hr. Dunno where 19 came from? Possible when they went to largeport 3100 with higher fuel pressure? Adam, you have any questions/concern about OBD2 swap, PM me. It would be stupid not to go OBD2 at this point in your cars life, especially how easy it is to do and the benifits. Not to mention the engine will just run smoother (speed density blows) Quote Link to comment Share on other sites More sharing options...
GOT2B GM Posted March 5, 2010 Report Share Posted March 5, 2010 just swap an entire 3400 into it. Quote Link to comment Share on other sites More sharing options...
AWeb80 Posted March 5, 2010 Author Report Share Posted March 5, 2010 not swapping till i build a motor. i just want to see what i can get out of this motor with a large port and the exhaust mods i have done. i'd like to see over 150whp. wiring does intimidate me a bit I'll admit. i'm good with mechanics though obviously.
