1988 Samurai Turned Buggy

Thinking about trying to bend this with a 10’ pipe in the axle…it will take ten times the force to bend 8” of steel, as opposed to the untrussed axle length. Not to mention the second truss may potentially require an additional ten times more force.

I remember one member put his Samurai powered buggy on a dyno, and got 20 hp to the rear wheels. Even 68 hp and 37’s won’t make enough force to bend those tubes. I just can’t see it happening.
 
It's not hp that bends axles, it's sliding down a hill into a tree or rolling and landing on that one corner.

You also are going to have 200:1+ gearing, so you have enough tq to break anything

I bent a front toyota axle in my samurai on 33s with 50hp and twisted a rear toyota axle housing on 37s with 70hp. So I'm not just running hypothetical here.

Like I said, It may be fine, but you took the time and spent the money to truss it, may as well finish it.

Thinking about this more, it's more like trying to bend 3' of tube with a hammer vs 8". The long piece will be more likely to absorb those impacts than the short piece.

Maybe we should start a truss thread in gen4x4 as I'm curious on real world experience with different trusses.

I think it was action fab who built a lot of axles for customers and actually didn't like trusses for the reasons I mentioned. He said he preferred to sleeve the tubes.
 
So YotaAtietoo hooked me up with a Toyota drivetrain. W56 with a doubler set up.

Then I called Trail Tough this week to ask about the RingR set up. They sent me a list of parts and prices.

Today I dug out my 1.6l flywheel I had from my 1996 Sidekick parts vehicle. It bolts up to the Samurai 1.3l. However, I’m definitely concerned about the weight of the heavier flywheel. Also kicking around having it machined to smooth it back out.

Anyone ever run this set up to a 1.3l? Any issues?

Heavy flywheel is your friend. Yes it will rev a little slower but it maintains rpm better than a lighter one.

Correct. IIRC a trackick flywheel is 10lbs heavier than a samurai one. Very noticeable increase in lugging ability. Plus you can run the bigger trackick clutch. The 16v clutch is 8.5” vs the samurai 7.5”. Trackick 8v and 16v flywheels are the same, so you can run an 8.5” clutch on either.
Of course I’m talking 89-98 trackicks here.

I run a trackick flywheel on my setup…EFI 1.3, homemade kicker 3, 142:1 crawl ratio on 34” LTBs/TSLs.

If I ran the numbers right it’s 223.92 which should be pretty awesome for the underpowered thing.

Left is 37’s, right is 39.5.

Does anyone know if the 1.3l shares the same head bolts as a 1.6l? I can’t find head bolts for the 1.3l on Rock Auto, Summit Racing, or ARP.

I want to say they are the same size, just different head types...hex vs allen head. I would think you could find the size specs on each somewhere, to confirm.
 
dang i saw this thread too late.

was gonna suggest use a pipe cap cut in half for the front of the diff. but glad i found the thread none the less. cheers

Slow going still. Trying to get the engine all cleaned, parts painted, and gaskets redone before Thursday.

Then next weekend the cleaning and resealing will continue with the transfer case/crawl box from YotaAtietoo.

Pics. Almost ready to tear down the head then the oil pan. Everything on the front and rear of this is an oily, greasy mess.

Making more progress than I am.

What are you doing for fuel/injection? I was looking around for some stuff for my dads VW and came across a Holley Sniper 1 barrel they claim supports 175hp. That would be legit for this. Simple wiring, set tuning, fuel injection. That or the Harley carb option.

Plan is currently to run propane. But fuel injection would be far better than a carb.

Take this for what it is, but I thought the same thing and ended up reading mostly negative things about them. Of course I can't remember where :homer:

All I'm saying is dive into it before purchasing.

Gm tbi and micro squirt, or even just factory ecu is a decent option as well.

My goal for this is simplicity. Like aiming for as few wires as possible. Keep everything SIMPLE. Propane seemed the most simple. Expensive, but so is any new EFI system. Propane tanks also don’t leak like gas.

If I hate propane I can change down the road.

I was just making a general statement.

Propane is great if you want simple and will tow it anyway.
 
after running propane for the last 5 years i can say i had a system and not having to run propane this year it is much easier. its all the little things. filling up tanks. hauling extra tanks. you loose power, but gain a simple set up. also the engine does not know if it is facing up, down or on its lid, ir will never starve for fuel. :) :lmao::lmao::grinpimp::grinpimp:

fuel leaks happen on propane , just not as much.

fuel leaks on gas. no i dont have them, maybe it will vent a tiny amount. and most of the guys i run with dont either. if you FATS is your friend when venting fuel. or 4 sides and down. i would look into a mega squirt like mentioned. lots of toyota guys run them too.

I already carry 2-3 5 gallon cans of gas with me. Propane tanks aren’t much different. Plus I found tons of used tanks for sale locally for like $15-$20.

In the midwest with Kungfoo and his buddies there were two situations where gas wasn’t optimal. Not sure if propane can smoke you out when vertical, but KungfooMasta’s buddy got smoked out. Then Kungfoo’s buggy was just pouring gas when he was laying on his side trying to get up an obstacle.

Like I said, if I get tired of propane I’ll switch it. Not a huge deal.

That's just poor plumbing.
 
lots of boost yeah. i did not because i kept boost low but made a big difference. less then 7 i think. i cant recall anymore because i could never stare at the gauge and laugh and wheel at the same time.
 
so stubs, he is on here. did a excellent write up back on the old place on how ho to do it.
here is the thread title if i recall.

how to turbo a 22r with propane. search that and i think you could find it. or hit him up on here
 
Shop is a mess and I have to lap in new exhaust valves. Every one of them leaked, but the intake valves looked new. Very odd. Have some blow by on the piston rings. Plan is to just run it, and look for a 2.0 to swap in later.

Pics from the week.

The new table is great for laying out an entire engine.

Block is mostly cleaned up now. Also realize how important it is to use oil cleaner frequently.

Next on the table will be the drivetrain from YotaAtietoo. :smokin:
