Toyota LPG kits fit or adaptable to isuzu's??

Postby trooper T/diesel » Sat Apr 25, 2015 6:34 pm

seen some on CL and E-bay for the 22R engine, being about the same size im thinking there would not be too much involved in it.
.
for a carb'e Isuzu gas engine G180/G200 or the 4Z engine's 2.0/2.3/2.6L the 2.0 or 2.6 would need to be converted to carb...

first link i found with google of a kit for sale.....kinda spendy gotta be lower cost kits some where.

other then putting the kit on i guess the other question's are...
.
#1 to go dedicated and raise compression to a point it can NOT be ran on ANY normal 87/89/92 pump gas as propane is around 110+/- octane.
#2 go BI-FUEL with a stock engine that can still handle 87 octane.
#3 or raise comp just to a point it can still handle 92 octane in a pinch..
#4 then there's E85 that stuff is 105 octane but in my area its price is WAY OVER PRICED and one place with in an hour of me that sells it...

Eliminate option #4. That ethanol garbage causes all kinds of problems. Especially with carburetors.

Just look on ebay for "impco" and it wont be long before you know what all you need.
Can be done for a fraction of that price.
Also look up how your tank needs to be mounted and how/where you will have it refilled before getting started on such.
They are popular with the rock crawlers since there is no liquid gas to spill out in a rollover etc...

+1 for chunk #4 off the list. It may be high octane but it soaks up a lot of water and sits in the station tanks for a long time.
FlexFuelFAIL! Just more garbage from you know where...

i guess the question is, how high of compression is practical with a 4Z engine.??? with out having valves hit pistons..

Johnny had one at about 9.5 maybe 10/1 that's still very 92 octane friendly even 89 if you don't rod it up high in rpms..
all he did was mix the head with smaller combustion space, big valves and the more aggressive cam, with flat top pistons.
i don't think he milled the block or head at all.. :|

guess you would have to put some plumbers puddy or something on the pistons, and bolt the head on, spin it over take head off and see how much clearance is left. based on that you would know how far you can mill it and not hit....

that's the budget way of finding out, there may be other ways. :P



interesting ideal air / fuel mix of fuels, found on the net.
does that mean what im thinking, that more air flow is better for LPG :?:

Petrol 14.7:1
Diesel 14.6:1
Methanol 6.4:1
Ethanol 9.1
LPG 15.5:1
CNG 17.0:1

Plastigage is the puddy used to measure clearances. It's readily available at most parts stores.

LPG on Isuzu petrols/gassers has been on ongoing issue here is Australia for many years, as it is bad news on G Series, C Series, 2.6EFI 3.5 And 3.2V6 due to LPG being to dry from memory and doesn't provide enough lubrication of top end and dries the valves out far too much, to the point where I heard GM Holden would cover any warranty issues for vehicles that were converted.

Never been a fan of LPG until more recently so I can't say I am expert, but there are some really decent direct injection systems now available for EFI vehicles.
Australian Members - Where the hell are you??
