rshissler Posted April 13, 2005 Report Posted April 13, 2005 Alright since it's gettin warm out im goin to start to pull the 2.8 out and fix my little knockin problem. I know im goin t hve to replace bearins and maybe the crank if its damaged. Is there anything else i should replace or check out? Maybe the oil pump? Quote
White93z34 Posted April 13, 2005 Report Posted April 13, 2005 uhhh, you could just replace the mainbearings but thats like working on a time bomb, just get yourself a good used 3.1 or 2.8, you'll be much happier. and besides you could have damaged something other then a mainbearing like a connecting rod, scared the crank, destroyed a endcap. its anyones guess. these engines are cheep enough anymore, just get a new (used) one.

rshissler Posted April 13, 2005 Author Report Posted April 13, 2005 alright sounds like a plan ii guess Quote
THe_DeTAiL3R Posted April 13, 2005 Report Posted April 13, 2005 Drop a 3.1 on there.. you'll just need a different MEMCAL chip for the ECM, VSS, and you can chuck the MAF sensor (since your's is a 88). If you decide to keep the 2.8 I'd understand... god I love the way those sound! Quote
rshissler Posted April 13, 2005 Author Report Posted April 13, 2005 i should look for a 3.1. why do they sound different? Quote
THe_DeTAiL3R Posted April 13, 2005 Report Posted April 13, 2005 I just find that 2.8s have a cooler sound. More of a higher tone if you ask me. Probably cause you gotta rev them up higher to get them going but maybe someone here has a better answer. The added power of 3.1 is well worth it though over having an 18 second car. 3.1s sound pretty damn close to a 2.8, but 3100s sound nothing like the 3.1 Quote
jeremy Posted April 13, 2005 Report Posted April 13, 2005 go with a JY 3.1, you will thank us once it is installed.... Quote
Brian P Posted April 13, 2005 Report Posted April 13, 2005 get a 3.4 I'm dying to know how he'd even begin to run that thing in an '88 car. I envision an upper harness swap, tranny swap, or custom memcal to say the least (3.4 program without the 60-E provisions?) How many miles on the 2.8 anyway? Quote
digitaloutsider Posted April 13, 2005 Report Posted April 13, 2005 Harness swap, transmission swap, subframe swap, ECM swap.. Quote
rshissler Posted April 13, 2005 Author Report Posted April 13, 2005 i really cant say how many miles are on the 2.8 because the guy i got it from changed the dashes because of a broken fuel gauge and he didn't remember if he put the other one back in or not. Quote
Brian P Posted April 13, 2005 Report Posted April 13, 2005 subframe swap Oh yeah!!! Good call! Easy swap man easy. Quote
rshissler Posted April 13, 2005 Author Report Posted April 13, 2005 o yea thats extremly easy you know since i was hangin off the bolts trin to get them off tryin to drop the oil pan Quote
cutlsp Posted April 13, 2005 Report Posted April 13, 2005 you need a 5 foot breaker bar and need to soak the bolts in pb blaster. you can make a 5 foot plus breaker bar with some exhaust piping Quote
