88pathoffroad Posted January 8, 2007 Share Posted January 8, 2007 Slick replaced an engine, she didn't swap in a 3.3. But yes, she is a very good asset! Go read this first... http://www.nissanperformancemag.com/february05/pathfinder/ Link to comment Share on other sites More sharing options...
milehighcowboy Posted January 8, 2007 Author Share Posted January 8, 2007 ok 88 i read the whole freaking article. front to back. even the ones digusing the mods not related to engine parts. i gathered that i want a VG33E block. what exactly is intailed in the block? pistons? or what? did slick do a write up of her engine replacement?

88pathoffroad Posted January 8, 2007 Share Posted January 8, 2007 To put the 3.3 in, you'd have to swap the crankshaft out of your old engine into the 3.3 block (cause the front end is a squidge different and won't work with your stock accessories) and swap the intake and FI over to it...I forget what else. It wasn't much, though swapping the crank is a big job all by itself. Link to comment Share on other sites More sharing options...
milehighcowboy Posted January 9, 2007 Author Share Posted January 9, 2007 so over all for a newbie it would be easier to just drop in a replacement engine that is the same kind. Link to comment Share on other sites More sharing options...
NismoSkyZ Posted January 9, 2007 Share Posted January 9, 2007 (edited) or a 300zx engine sly Edited January 9, 2007 by NismoSkyZ Link to comment Share on other sites More sharing options...
milehighcowboy Posted January 9, 2007 Author Share Posted January 9, 2007 and what would that entail? i do not have the money to get a tranny as well. i am happy with power just not MPG. i just need a new one. ben Link to comment Share on other sites More sharing options...
Simon Posted January 9, 2007 Share Posted January 9, 2007 I think there's more to the 300zx swap than just throwing it in. Easiest way is to just get another Pathy engine, and toss it in. As previously mentioned....do all the maintenance stuff while it's out of the engine bay though. Link to comment Share on other sites More sharing options...
88pathoffroad Posted January 9, 2007 Share Posted January 9, 2007 Yup. A straight swap is much easier to deal with than a conversion of any kind. The N/A 300ZX engine uses different external parts, too...water pump, oilpan and oil pump pickup, crankshaft snout and pulleys, etc. Link to comment Share on other sites More sharing options...
milehighcowboy Posted January 9, 2007 Author Share Posted January 9, 2007 so there is no way to take a complete 3.3 engine and just drop it in to my truck. no diving into the crankshaft and what not? how hard would it to be to rewire the ECU for the 3.3? (put the ecu from a 3.3 in my truck removing the old 3.0 ECU) Link to comment Share on other sites More sharing options...
lgranch Posted January 9, 2007 Share Posted January 9, 2007 There are very talented people who can do just about anything when it comes to swaping motors. Please understand ANYTHING except a 1990 to 1993 VG30E in your pathy is not straight forward. A 1994 and and a 1995 are simple addtions. These were OBDII motors and teh computers are slightly different, but you can get the motor to run without the O2 sensor working. (1994 motors split between OBDI and OBD II) 1987 to 1989 VG30I motors require parts swapping because if you use the computer from the 1992 there are sensors missing on the motor blocks, but again not too bad and do-able. Past these swaps it take some talent to make thing work right. The ZX is about as hard as the 3.3VGE (1996). Japanese take out motors do not match exactly either and require some fussing. if you were not so far away I would make you a deal on a 1991 motor that has been bored out for more HP. (brand new rebuild) But shipping makes this a stupid move. Make sure you understand and are confident in your talent level. Slick is talented on engine swaps. I have done several. 88 is an all around expert. These things can be done, just make sure you do not enter the program with blinders on. Link to comment Share on other sites More sharing options...
Simon Posted January 9, 2007 Share Posted January 9, 2007 OBDII motors in 94 and 95 Pathy's?!?!? Mine's a 95 and it's an OBDI I thought nissan went to OBDII in 96... Link to comment Share on other sites More sharing options...
Pavelow Leaks Posted January 9, 2007 Share Posted January 9, 2007 obd II was made mandatory in 96 most manufacturers had gone to it a couple years before. Link to comment Share on other sites More sharing options...

(put the ecu from a 3.3 in my truck removing the old 3.0 ECU) In addition to the 3.3 ECU you would also need to gut most of the wiring harness from the 3.3 donor vehicle and splice it in to your 3.0 harness AFAIK.

milehighcowboy Posted January 9, 2007 Author Share Posted January 9, 2007 ok thanks guys. i am going to try and find a VG30E engine to drop in more than likely a 90 through a 93. i hope. ben Link to comment Share on other sites More sharing options...
88pathoffroad Posted January 9, 2007 Share Posted January 9, 2007 90-95 VG30E will work. They didn't make ANY changes from 94-95 on the engine, regardless of OBDII specs. OBDII is merely onboard diagnostics, not engine management. Link to comment Share on other sites More sharing options...

OBDII is merely onboard diagnostics, not engine management. u can also use the vg30 from the 86.5-90 but would have to swap the intakes (and i believe that is all)...i used an 86 maxima vg but it involves swapping oil pick up, oil pan, accessory brackets and relocating dipstick and some other stuff im prob forgetting but nothing really difficult... once you have found an engine i would try to run a compression check (most junkyards have the ability to do that) i would change valve cover gaskets, cam seals, tbelt, water pump, rear main seal and oil pan seal before even dropping it in if it were me...

OBDII is merely onboard diagnostics, not engine management. While that is a correct statement, it does depend on what you swap. The O2 sensors are not the same and not interchangable. They are two different sizes even. Link to comment Share on other sites More sharing options...
