Re: Going down?

From the picture it appears you don't have it lowered enough nor are the tires/wheels large enough to present any of the potential problems I mentioned. A 2" t-bar crank will still leave some suspension travel, 3" is about the max that is practical for retaining any ride quality, 4" w...

Re: Going down?

A couple of other problems that you're likely to run into: - to lower the front T-bars enough to match the rear you will lose practically all front suspension compression making for an extremely harsh ride. - with the front tires tucked into the fender opening the turning radius is greatly reduced o...

Re: Webber swap 84 1.9

You might want to look into this air cleaner adapter, lets you use any 5-1/8" round throat air cleaner & filter. Pay attention to clearances where the filter housing overlaps the valve cover & hood clearance. http://www.carburetion.com/Products/ProductDetails.aspx?part=99010.457 Use the...

Re: Changing Rear End on a C223

"Is there anyway to tell without opening the punkin?" Yes. -Do you have a tach? What's your rear tire size, specifically the diameter? Since you've already stated your speedo is dead on record your rpms at a given speed(60mph is easy since it's one mile per minute) in 4th gear(just to make...

Re: Changing Rear End on a C223

Your truck has a corporate Isuzu 10-bolt rear. The factory available gear ratios were 3.42, 3.73, 3.92, 4.10, 4.30, 4.56 & 4.77. It was common for the diesel 5-speeds to have 3.73 gears. So to lower your rpms without changing the entire rear axle assembly you are limited to a 3.42 gear ratio or ...

Re: Webber swap 84 1.9

Kit K696 from Redline should be what you want. Shop around for the cheapest price, here's an example https://www.ebay.com/itm/Isuzu-Pickup-Trooper-Chev-S10-1-9-Weber-Carb-Conversion-Kit-K696/330622469878?hash=item4cfaa286f6:g:kncAAOSwD39ackiw See this link https://www.planetisuzoo.com/viewtopic.php?...

Re: EGR delete question...

The EGR does not supply vacuum, it consumes it: the exhaust gasses are pulled through the tube by the vacuum created by the pistons, the same vacuum that operates the distributor vacuum advance & carb secondary & sucks air/fuel into the cylinders. There are about three vacuum controlled emis...

Re: EGR delete question...

EGR enters the intake plenum below the carb so I don't see how it could stick a throttle plate. Probably it's just in a bind, see if you can force it free, then clean all linkages & moving parts well with carb cleaner, lube lightly with something like WD-40. The carb secondary is vacuum operated...

Re: Surely someone can tell me..

The threads into the exhaust manifold and the fitting under the intake are M22x1.5, search for a plug or bolt of this size. I found some short plugs from China of this size that installed with a 12mm Allen wrench, but I can't remember the special name they were called. If you never plan to re-instal...

Re: What size 17inch tire fits the best on a 93 isuzu pick up

Look on the driver's door pillar for the factory tire size, every 1" increase in diameter over that stock size will change the effective final drive ratio by about 3%. If you were to use a 3" larger diameter tire it would make your stock 4.10 gears seem like they were 3.73s. Your speedo re...

Re: Sway Bar Question 1982 Diesel 4x4

Don't positively know, but would guess on top. With most sway bars the end is usually close to horizontal with the end link usually close to vertical, the length of the end link is whatever it takes to get the bar end horizontal. Look at where the center of the sway bar mounts, to get the ends horiz...
