engines!!!!!!

[crazzyguydj]

Ok, this summer i decided to start a project and fix up a 1g 4g63 to a 2.4 stroker. Well, I went to the junkyard for an engine and they said they could have one there in an hour for $100. So I went back over there a little later and they had an engine that they said came from a 92 and looked like it was turboed because of the oil lines (7bolt). This is what they gave me.
Well, I said I didn't want that engine because of the bad bottom end so they said hey we have another one over here with a good bottom but bad top end. so now I have that engine and another 6 bolt 4g63 that they say has a bad top end. Here is a pic of that engine.
well what do you think I should do?? The 6 bolt is the engine I will probably be putting all the good parts on, unless i get another complete 1g. Even together they are missing so much stuff it is crazy. Do you think I should put the good bottom and good top ends together and get a rebuild kit or stroker or should I just wait until I can buy a complete 1g with a blown engine that way I know I have all the parts? My goal is to eventually have a 2.4 1g eclipse and I just wanted your input on what the best way to get there would be.
Sorry it is so long. Thanks, Derek

don't get either one unless you really want to get into some dirty work. wait and get a complete motor unless you like solving fitting problems and shit like that that come along with any type of swap.

i already have them both... 100 bucks

The motor with the good bottom end doesnt seem to be missing much from the pic. The belts are missing, but those and half of what you can see on that side of the motor will be getting replaced with new parts anyway. Timing belt cover isnt cheap at ~80 bucks, and its missing a cam gear. But you can get those things used from poeple all day.

Ok, I just finished completely taking the worse of the two engines apart and the bottom end in this thing was worse than I imagined. here is a pic of some of the random stuff I pulled out of it.
The connecting rod snapped in half, the connector on the other side of the connecting rod snapped in half, im not 100% sure what it's called but the bearing on the crankshaft snapped, #3 piston has scrapes on the top where it hit after the rod snapped, and more metal shavings than I can hold in my hand. So, all you turbo owners, be smart with your engines and try not to let this happen to you! here is a pic of the bottom end with nothing in it.

Here is a pic of the head pretty much disassembled with the exeption of the valve springs.

On the flip side you can see where the piston slapped the head. Hopefully by the end of the summer i will have something that at least resembles a decent engine.

[gthompson97]

i have a bottom end that looks something like that...but i have TWO nice 6" round holes on both sides...you can look through the block. i'll post pictures later.

Ok, i just thought i'd post an update. As of 5/2 the head is in the shop getting cleaned, pressure checked, and all that good stuff. I'm about to do a search on what I can do to maximize the power of my head... or you could just tell me here. I'm really doing this to get an engine more powerful than stock because from the beginning I just decided that wasn't good enough. well I was considering the stroker but I think now i'm just going to go with slightly larger pistons. Maybe .060 over or something. What do you guys think? How can i maximize my 2.0? (Or maybe 2.1 or 2.2 with the pistons). thanks

[gthompson97]

.60 over is alot. the farthest i think i would go is .40 over. you can put in dual springs and titanium retainers. upgraded cams and also port & polish the head. you can also take and put 95 pistons on 1g rods and have a nice 500+ hp combo. from there on it's just regular mods to make any car faster.

[crazzyguydj]

95 pistons? thats a lot of pistons for a 4cyl.... just kidding, what do you mean by 95 pistons? You mean of a 95 eclipse? Also, what do you mean by dual springs? And by 500+ hp engine you mean it can withstand that much hp? well, im not looking to turbo so I really want to put in things that will raise the hp, not only the things that will make it withstand the hp.

[gthompson97]

the 95 pistons are the year 1995, they can be machined to fit on 1g rods. this is an upgrade for some turbo cars. i thought yours was a turbo.

dual valve springs will help in higher revving. for a n/a.....cold air intake, bored throttle body, port & polish head, port match intake and exhaust manifolds, more aggressive camshafts, maybe some adjustable cam gears too. that should give you a little more power. you could also do a complete aftermarket exhaust system. header back with the cat removed. go to dsmtuners.com and follow the 1G n/a mod list.

Stock springs are good for 8500 comfortably (thats what I run). Only very well built trannys shift well at 9k, and it takes a mean setup to be able to make power up there even with big cams. Strokers are even less likely to be reved high. I dunno, I guess I was just never fan of expensive valve train parts, since I never had trouble with the stock parts even with over revs to over 10k (and that should say a lot, since I broke damn near everything else).

[crazzyguydj]

As of now I was thinking about getting the 2.4 crank and getting a rebuild kit with pistons that a .040 over. Thats all I have so far i really need to know what to do to the head that requires machine work seeing that that is the part of the engine I am working on right now. It is still at the machine shop and I need to tell him what he needs to do. I am going to do most of the "putting together" but I need him to do the machining. I think the next step will be port and polish, and then I will take it back when i get the pistons.

[crazzyguydj]

sorry I have another question I bought an engine stand and the engine I have only has one stud coming out of the bottom. I need to know what bolts to use to hold it up (how long and what size). can I use any of the bolts that came with the engine or do I have to buy some? thanks

[gthompson97]

if it threads into the block then find the right size bolt for that application, other than that, just take a normal bolt and put it through the mount and put a nut on the end.

[crazzyguydj]

ok, I got the engine on the stand with a bit of work (had to modify stand and then somehow flipped it up on the stand). And now I need to know what year this engine is so I can start buying parts for it. My other engine had a cage going across the entire crank and this one has like 3 separate pieces. This is a 6 bolt. The pickup screen is more flat and has a brace where the other 7 bolt had no brace and was more of a dome. The engine code is MB5157.

Also, to give an update of the latest plans, this is the list so far.
Pistons (.03-.04 over) Rings
Connecting rods
rod bearings Main bearings
2.4 Crank
Timing belts Accessory belts
Water pump
Spark plugs Spark plug wires
All gaskets
Header, and get the local shop to run the piping back from there
Lifters
CAI
around 600cc injectors
And that's it on the list. If there's anything else you think I should add tell me! I'm open to suggestions.
