16 valve OR 4.3L.....second thoughts...
Who would have thought.... after a while of playing with the 4.3L swap and no really problems yet, I'm actually thinking of passing on it and moving into the 16 valve class. [img]images/graemlins/crazy.gif[/img] I haven't got everything I need yet for the 4.3L swap, and I now realize that price-wise, it is going to get really expensive. Maybe more so than I'm willing to pay. Guess I just want everyone's help on what to do here. Here's the situation regarding each engine option:
4.3L engine option
Ok, I already have the engine, tranny and transfer case. The transfer case (NP241) has already been rebuilt and has a SLE on it. I can easily sell this case and recover part of the cost. The engine would be rebuilt (whether needed or not) and the tranny not. Price of rebuilding the engine is up there not to mention the overbore, new pistons, and performance cam. Also, will have the PCM reprogrammed.
Along these lines, I have the harness (about $350: BTW, all prices in US funds) but can return it, and a Mustang rad. I would use this rad in either the 4.3L or 16 valve, so no loss there.
Still needed for the 4.3L are: clutch, flywheel, hydraulic clutch components, accel. cable, custom exhaust, cutting the driveshafts, NEW aftermarket dash gauges, interior wiring harness, dash work, tranny shifter if this one can't be made to work, etc. etc. etc.... the list goes ON! [img]images/graemlins/cussing.gif[/img] You get the idea. OK, so I should have thought of this earlier but the allure of driving a Chevy V6 got me [img]images/graemlins/shocked.gif[/img] I know, I know....
1.6L 16 Valve
Now, I have the tranny and transfer case so no cost. Would probably want to rebuild both though and replace the clutch. Would need a 16 valve engine, wiring harness, and 1.6L kit. Funny cuz I had a lot of the parts with my old 8 valve 1.6 and sold them all, almost new! LOL Live and learn (I've been doing a lot of that lately). I have Toy driveshafts and axles already and would use them no matter the swap. Just need driveshaft adapters.
The 2 engines would cancel each other out either way. So would the engine harnesses. But the 16 valve would be a hell of a lot easier to do, and would be finished a lot sooner. Not to mention, BETTER fuel mileage, less hassle with DMV and emissions issues, lower weight, etc.
I would need to gear the Zuk though to get it to near stock figures. Which brings me to a question: what diameter are stock Samurai tires? Can;t remember cuz I've never had them!
So, what would you guys do? The 4.3L or the 16 valve? Money is a big issue of course. Not to mention the work involved. I bought this Zuk to drive in, not wrench on.
I'm only concerned about the performance on-road of the 16 valve. With my larger tires and heaver axles, should I worry? It will be geared like I said, to near stock #'s. I'm just wondering about highway cruising. Need to be able to drive 70 MPH easily, even in a head wind. Don't want to have to drop gears everytime a hill comes along.... anyone?
Thanks for the help guys.
