$600 bucks for an engine craigslist already built with Je pistons and eagle rods, hmm i kinda of want to buy it but scared.
 
if he has receipts and can prove that's what the engine has, that's a good combo
 
Your engine blew up cause you ran lean No fuel means cracked ring lands if your gonna run stock internals I would definitely get a safc , bigger injectors 550's and a walbro 255 fuel pump the fmu is old technology and really doesn't do much I would buy the motor on craigslist and pull the pan to make sure it has the stronger internals, install new rings and get the mods I have named off in order to keep your new engine alive.

I can't seem to stress enough, make sure you realize all the additional charges, Head gasket, Hardware, other gaskets etc, machine work.. if there is no paper work , or mileage with the engine, then you have other "X" factors that could translate into more then your wanting to spend...
 
yea i know. I found a place that rebuilds engines for $900 so probably going with that and i'll lose the turbo
 
Well like I said.. Rebuilding a 420a isn't just in the Chilton.. There's special things wrong with our engines that need to be fixed.. But I'm sure they know everything about the 420a.... (sarcasm)

well if anything i just want 8-10psi not looking to go that fast as my car is automatic. so i just want 8-10psi safely without breaking again. I would think that piston cracked cause of how many miles it had. i bought it used at 130,xxx miles in 2005 didnt start using it until 2007 and before the car was used by a company to travel to san fran, las vegas, arizona so it had a lot of highway miles on it.

it cracked where the rings are at.

thanks man ive always wanted to know where i could find this.

its just better than oem, according to the shop they are performance and told them i was going to put a
turbo on it. Got the three layer gasket. And 1 year warranty for $1200 which isnt bad.

alright so im going to drop my engine soon and what are my tunning options i just have the 12:1 fmu that hahn supplied and should i be fine for a while until i save up for something thats worth it.
 
One thing you have to keep in mind, if you build the motor thats all fine and dandy but if you still have an improper fuel set up you will blow it again. The safc is almost useless on a 420a eclipse thats boosted, think about how the safc works. It modifies the Map signal going to the ecu and bends it to make the ecu squirt more fuel in it. Well when the 2gnt ecu see's positive map pressure it cuts fuel because it doesn't know what to do, the only reason people used to use Safc's on the 2gnt is because they where running stock turbo injectors and an FMU/SFMU and couldn't idle the 450cc injectors on the stock ecu. It was a hack and it did work, but it didn't work well. For the price of the safc you could run MS and if you can wire the safc in then you SHOULD be able to wire in MS. People get scare about it but its really all elementary stuff. If you think MS is still over your head then invest in portfueler from Hahn, I know there where/maybe still be quite a few of them for sale on here or 2gnt because a lot of people are going with MS now. So in short, a stock motor can handle the power you are trying to pump through it, but you need to figure out your original problem or it will happen again, even on a built motor. Forged pistons/rods doesn't mean you can do what you want and your motor will be fine...which ever way you go good luck!
 
I agree with above, keep in mind, id read that warranty, its hard to believe any shop will warranty a motor, especially when your turbocharging it, and it didn't come factory turbo.. Its like getting one rebuilt, then blowing it b/c Your fuel system inst right, .. why would they warranty your mistake.. I think ( and this is from alot of experience with "performance warranty" ) which really means, they warranty that they torqued the bolt to the right spec.. nothing more.. if a rod fails, not their fault, they didn't build the rod. ie they wont cover it.. if a rod cap comes loose and kills your engine, then that's on them, but they will always come back and say that Torque is for a N/A engine, and not a boosted engine, needless to say in court you would loose this battle.. Thats why there are virtually no warranties for aftermarket performance parts..Just my .02. warranty sounds nice, but in the real world, they are rarely worth anything..Get your fuel in line or blow another one.

Did they use factory head studs? if they did, ill bet money they didn't shave the Drivers side rear bolt down 3-4 threads....which means you may have the head gasket fail prematurely...thats what i meant buy saying find a engine builder who knows the 420a motor, not just A motor..

All stock 420a head gaskets are 3 layer.
 
Knock off eagle rods.. So a fancy work for stock ones LOL.. They are from DSM grave yard..They are not upgraded, just an aftermarket stock. Im not sure about the rest, but im interested in a parts list to, and weather or not the replaced Oil/water pump.. b/c 12oo for a full stock rebuild, seems cheap.

And yes i just looked, they are 4 layer, the middle 2 stick together LOL!
 
yea i know wanted to get performance brand but thats when the money came into place and is an issue. its a 3 layer metal head gasket. my injectors i have are from hahn and i think they are 270's not sure. And yes they did replace water pump and oil pump
 
thats pretty cheap where did he get his parts at ? would of paid extra $200 if i knew. At the same time im not boosting more than 10 just 8

As for your gasket, I take it it wasnt a Mopar one since its 3 layer.

They replaced it, but with reman, or New, or knock off? Mopar and melling (same thing nowadays) are the way to go, some of the knock off stuff doesn't hold up to well..
what all did the "replace" any timing components?
 
i dont think so, thats where the warranty comes in.
 
Ok.. why would they warranty a issue that Dodge/Mitcu wont even warranty...Sorry dude...And im guessing they didnt do anything with the timing, you may want to replace your tensioner, or upgrade while you still can. I feel fail comming on. They wont warrnty a defect from the factory, thats not their fault. The rebuilt as the book tells them.. the book is wrong/missing things. so what does that tell you about the build.

^ Whatever happened to this? I think head gasket and rod talk is kinda a mood point if you are still running lean. I think you said you had a 12:1 FMU and you are running a walbro 255 right? Also I assume you have the missing link or FCD? If you arn't changing anything with your fuel setup I would suggest adding a wideband so you can watch your air/fuel ratio so you don't have to go through this again. Good luck :thumb:
