All parts ordered and accounted for. Bagged, tagged and marked with torque specs. Assembly took 2.5 hours… but the 14 hours of prep work, 2 weeks in a machine shop, and wrong-parts-delivered fiascoes straightened out prior to assembly.

yeah mine had balnce shaft eliminator and arp head studs which helps and just a felpro head gasket and i didnt have any problems with it at all but i sold it before i got to put alot of miles on it unfortunately now i got a srt4 swap going into a neon i was thinking of doing a colt 4g63 fwd swap but got enough projects for now lol / is that the gsx rear end u put in the colt?
Nobody’s commented on my editing before, and I appreciate the feedback because it’s a lot of work cramming 150 minutes of video into 3 and change.
But thanks for noticing! I’ll try to keep crankin’ ‘em out like this.
I’ll post videos for sure. The Colt’s getting all the attention from November-April, so I should be able to get video of it running next season.
I evicted the balance shafts and ARP’d everything, so it’s not exactly bone stock. The motor had 150k and cylinder #2 was only 5 PSI from the service limit, so it needed to be freshened up. There was nothing mechanically wrong with it, though.
To ME it’s not a lot of work, and I have a desk job so it’s really sorta like therapy. STAY TUNED!
yeah stock internals will be fine with a 16g / just all that work for a stock engine but makes sense it should scream make sure u put up video of that colt in action expecially with the awd / i had a 16g with stock 6bolt and didnt have any problems at 25psi just traction issues lol mine was a 97 gst
Yeah, some people feel like that. This motor’s going in a 2200lb Colt, not a 3200lb Eclipse. So it’s not likely that I’ll need to make 500+hp to run 10’s, but it should still hold up if I ever get there. The most it will see is probably a big16g… and I can’t justify $400 worth of rods and $550 of pistons for that. That would be a waste of money when I have a few other modded cars to keep up with.
I also have yet another spare 6-bolt for whichever DSM dies first… just in case.
all that work and looks like u put the stock cast pistons back in ?? should of put in new forged pistions / still a nice video looks like a fun build
I like the how the video flows with the music, the time-laps, and the effects of the accessories being added.
The OEM forged 6-bolt rods weigh 497grams each. That’s heavier than the rods in a 427 Chevy big-block. The crank journals are an inch-wide on the “big rod” motors.
The turbo I’ll be using won’t really benefit from running it higher than 7500rpms, and I’m not building up the tranny because the car will be 1000 lbs less than an Eclipse.
I am considering upgrading the GSX, and if so, those parts are also compatible with the Colt.
I watched a 1g ‘92 put down 455awhp on stock internals and stock transmission with 130k miles on it. 6-bolt motor. I won’t ever need to make anything more than that in this chassis so that should be more than sufficient.
I spent $3500 on machining, headwork, internals, mods and everything else to my 7-bolt, and I’m only making 354awhp with it. …plus I have another complete spare 6-bolt “just in case”… and could use it in either car.
so you have the stock internals right? Why didn’t you choose to bore it .20 over and get like wiseco pistons and eagle rods. Are the Spring/retainers, and cams stock too?
The manifolds, turbo, fuel rail and heat shields/timing covers are on. Trans is cleaned up (have ACT 2600) but it’s staying on the stand until the auto->manual conversion is finished. It has a manual steering rack and no AC & I took out 36 lbs of powered seatbelts. Cage (main loop and crossbar) and racing seats are next (for racing harnesses), and a battery box, cut-off switch, fuel cell after taxes. ‘can’t wait. Probably 2200-2300 lbs. Shooting for a mid-high 10 second street car.
Oh, I was talking about the colt. I seen at the beginning it said “November 18, 2007,” I didn’t know you finished it or shelved it. Definitely the swap is worth it from looking at the other videos. Fwd no traction until 90mph lol. By looking at the other video, I guess you have to make custom motor mounts since this isn’t the gt model. How much awhp you looking for? Is this going to be a DD, or fun toy? But keep us updated with your progress, and good luck!
Which one? The donor or the recipient?
The engine donor was a PA car and a rust-bucket. It was cheaper and easier to buy a whole car & rebuild the engine than than just a 4g63 engine. It got stripped and crushed, and I donated what I couldn’t use to some GVR-4 owners (I have some Indian blood).
The recipient (’91 Colt) was wired with a ‘92 harness over the past few weekends, and will be receiving this motor very soon. The interior and engine harnesses have been wired together now.
What happened to the car?
Ok cool thank you.
Use the drivetrain from an EVO 8 instead of the ‘90-99 engines. It’s a better fit. Google it.
Awesome video i have a 96 eagle talon fwd 2.0 420A engine non turbo automatic transmission but I’m to get a Awd 5speed 4g63 turbo engine.
