that is a nice header I didn't know they made the 4-2-1 headers for these engines I have only seen the pacesetter 4-1
our carb isn't the same as yours you guys have the Stromberg nikki and we have a hitachi dch340/dcp340 depending on the year, they look pretty similar but not sure if they are directly compatible
I cut the Chevrolet part out of a trashed tailgate I had but it isn't in very good shape and isn't the full skin. as far as I know there is no fiberglass tailgate for these trucks, not much reason to lose weight off the light end
as far as the intake goes im really not sure if it would cause coolant circulation issues if you plugged up the ports but I don't think it would as long as you made sure to reroute the heater core hoses
Yep they are a nice set of headers, very neat fit. Made by a company called "Wildcat' part #084, they have 1 & 1/2" primaries and 2" main pipe. I'm not sure if they're still available, but there's been a bit of a revival in the Holden Gemini scene with the G161, G180 & G200 series engines. A firm over here have a modified EFI manifold available, plus have blow through turbo induction manifolds, and CAD designed mandrel bent turbo exhaust manifolds for the Isuzu G-series engines.
Before I get too carried away with this induction manifold, I'll be comparing it to the one on the 4x4 and pick the better of the two obviously. The fuel chambers on this one seem alright, but the coolant galleries are pretty corroded
I don't really need the heater option as the climate where I live is mostly sub-tropical. It can get cold in the winter months, especially at night, but most of the time it's great weather. But for sure, I'll investigate any potential coolant circulation issues if I was to plug the holes.
But yep, before any machining or anything gets done, it'll pretty much be a case of pull down both engines & clean all components thoroughly, inspect for cracks/fatigue etc,,, pick the best components from both engines and set them aside before refurbishing and assembly of the engine.
In the last few days I've found out that I can get a brand new Lynx manifold & Dellorto DHLA 45 or compatible Webber side draft or even twin SU Carbs to fit the Lynx manifold for a reasonable price, but I haven't been able to get hold of any feedback from people who have used these configurations on an Isuzu G series. So I may even just go that path if it'll save me on the time needed to clean up the manifolds I have and then machining costs? The Dellorto & SU side draft looks pretty 'WILD' though I must admit
The down draft Webber on a stock manifold that's modified for better flow seems to be a popular choice on a G161, but I'll do a bit more research on what other options are available.
