Huge lack of power on road.
Yesterday I took my Samurai for a drive on the highway. The truck hasn't been used on the road for years, so I don't know how it use to be on the road. I have a major power issue as soon as I hit 2nd gear in high range. 1st is fine, then when I shift to 2nd at about 5500 RPM the RPMs drop and it takes forever to get up there again, and I have to floor it. 3rd and 4th take even longer to gain speed.
I currently have the following on my 87 Samurai: Toyota axles front and rear with 4.10:1 gears, GRSII t-case (18% high range reduction), 33x13.5-15 Swamper LTBs, Suzuki Swift 1298CC block.
I tried coasting to a stop when I was going a decent speed and it didn't seem to stop that quick as if the brakes were dragging. My front brakes drag a bit but not much. I can turn the front tires when the vehicle is jacked up without too much effort.
I know that I should have a lot more power and more oomph than this. Longzuk has the same block as me, and with a stock t-case and 5.12's his zuk seems to go pretty well with 33x12.5 MTRs.
Any ideas on how to fix this? I'm going to replace my front calipers, and if that doesn't help at all I'll move on to the engine..
