Title: Rebuild the 1.3 or move up to a 1.6
Post by: GO_OUTSIDE! on August 13, 2012, 09:59:02 AM: I just spent the past 3 weeks working on my first samurai. http://www.zukiworld.com/forum/build-diaries-how-to-diy/saving-an-87-samurai-from-the-wrecker-budget-daily-driver-plus-trails-build/15/ (http://www.zukiworld.com/forum/build-diaries-how-to-diy/saving-an-87-samurai-from-the-wrecker-budget-daily-driver-plus-trails-build/15/)

Today I took her to work and along with the smell of bad jetting (too lean I think), the truck is slowing down traffic. She pulls strong off the line but stops making power around 50mph. I am running 4.91 gears and 31" allterrains. It has a Tri Y header and new full exhaust. The PO replaced the stock airfilter with one of those cone type filters.
5th gear is only available down hill.

sounds rich, but even when tuned 1.3 is anemic

the axle gears help, but lower t case gears affect 2hi in samurai and you will benefit (you will do this even if you swap to 1.6; eventually)
play with this to see where you want/need to be:

But 1.6 FI is the answer to your question anyways. ;)..

The idle is screaming fast, that could be another contributing factor.
The 4.91 gears are Tcase gears, Lowrange claims 18% reduction of high gear.

Post by: GO_OUTSIDE! on August 15, 2012, 10:11:57 AM: I downloaded a FSM from suzukiinfo, awesome manual, I forgot how bad Haynes manuals are.
I am heavily leaning towards a 1.6L upgrade. How can I be sure Im getting a good engine before I go through the effort of putting it in?

The cost of the rebuild kit is one thing to take into consideration, but don't forget the bill at the machine shop. Don't know what is available around you, but you're looking at a couple hundred $$ for bore/hone, and the costs go up from there depending on what is needed (things like valve job, head machining, block decking, crankshaft grinding, etc.)

My vote would be to do the 1.6L swap. The 8 valve is a super easy swap and there's no substitute for those extra few cc's.

Post by: GO_OUTSIDE! on August 31, 2012, 08:11:03 AM: I bought an 8V from Sean at aftermarket 4x4, I am in the process of replacing the seals, belts and water pump. I am hoping to have it in and running this weekend.
Any one know where to get an FSM by tommorow so I can get the timing right, since I screwed up and lost track of it? Suzukiinfo doesnt have one listed for the 1.6L 8V.
If this is easy i am very glad I didnt choose hard.
