Default Going to redo some part of my truck, need more towing power, flywheels?

1986 4 Runner, has 4wd, and a 5 spd. Total mileage on everything (except clutch) is 68k. Clutch has less than 400 miles on it, and is a stronger than factory clutch.

Car has 120 hp, 145 Ft/Lb of torque. I am told the exhaust on it is very restrictive, and I can pick up a real 30 hp by putting on a new header and a less restrictive exhaust. I can get a custom exhaust done for the cost of parts. I plan on doing that before trying to tow the boat.

The owners manual states that the max towing is 3500lb. The boat normally weighs around 3000lb with the trailer, and loaded up with gas, drinks, etc.

There are flywheels available, stock is around 22lb, I can get 15lb or 30lb. Would I want a 15 so it is less rotating mass, or a 30 for more momentium? I just want some more power to be sure it will get up the ramp.

Not that I know anything , but , Normaly light weight flywheels are for race cars that will be torndown all the time and replaced . In my opinion , The lighter thinner flywheel would be prone to warping from the rapid heating and cooling of it . I would stick with stock .

You can get a high flow air filter , better exhaust , do a tune up on the engine ,(people think spark plugs , caps, rotors , and wires can go for years ! They can't !) Use synthetic oil in the manual trans and rear end gears . It makes them turn easier . You could look at some kind of "CHIP" for more power too . Lots of little tricks add up in the end . Turn the A/C off when needing more power , put a switch to the alternater to shut it off when needing more power . Well , you might not need that much help !

My suggestion is to add a torque plate and boost restrictor.

I believe that golf cart has low range in the 4wd. Launch ramps should be no problem...if the frame doesn't tear out.....Got rust? Those poor ole Toys rusted out BAD...

Dont want to put a lot of money into it. I only have 200 into it now. Just needs to get up the ramp and a 1/2 mile down the road to the house. And there isnt much rust.

The lighter flywheel will not add even a fraction of horsepower.. all the lighter flywheel does is allow the engine to go up and down through the rpm range faster.,,, the only horsepower gain is the small amount that is lost having to accelerate the mass.
