No Compression

Postby Ttubbs » Sat Jul 25, 2020 5:36 pm

my 1.9l 84 gas burner seems like it is on its las leg. cyl 1 is 60lbs, 2 is dead, 3 is 60 lbs, and 4 is 90. Think im either going to overhaul it or maybe swap it for the v6 rodeo motor or maybe even a cumins 4bt swap. Any advice on the best path forward?

I'll tell you right now the 4bt is a terrible idea. Honestly it's an overrated engine. It's okay in a bread truck but that's about it. Better for off-road IMO. It's well over 750lbs wet. You'd have to lift the body way up and I don't know that it would even fit length wise...

Even if you swapped in a C223 from another P'up, you'd also need its transmission, and possibly the rear end.

A 1.8L 4FB1 diesel would be the easiest diesel swap.

How's the body, frame, and interior?

Best swap would be to throw a 5 speed behind a carbed 2.6. that sucker would fly real nice

I think the folks on the LUVTruck.com site reported issues with the distributor location on the 2.6L. Is it in the rear, against the firewall? Also, seems this would just about require using the MUA-5 transmission, which also reportedly doesn't have enough room.

Personally (from having a 2.6L Amigo), I thought that engine way too temperamental. The EGR system caused constant performance issues, and the head gasket eventually failed.
