ThePog Posted November 7, 2016 Share Posted November 7, 2016 I have a 4wd townace ute with a 1.8 carby 2y engine. The engine is strong but the carb lets it down. We have fucked with it, the garage has fucked with it but it runs like a bag of shit, hard starting and a massive flat spot, plus it uses all the fuel.. A man on TM has a 3y injection setup, plus there are no doubt millions of 3y and 4y engines everywhere. So what i want to know is will that 3y injection setup bolt onto the 2y, or am I better off sourcing a complete injected 4y and taking the punt it will bolt up. Learn me.

thegreatestben Posted November 7, 2016 Share Posted November 7, 2016 These are pretty lego, I would go straight to 4y. Got to watch the coolant jacket behind number 4 on the head/block eroding away. So easy to spanner though. My experience is all while they are in a forklift though so can't help you beyond that and maybe LPG haha...

ThePog Posted November 7, 2016 Author Share Posted November 7, 2016 It does have all sorts of vacuum emissions bollocks on there, some of which is contributing I am sure. So the manifolds are a direct swap etc? Quote Link to comment Share on other sites More sharing options...
thegreatestben Posted November 7, 2016 Share Posted November 7, 2016 Probably to the engine but vans are usually a bit tricky, highlux ran into this problem on his hiace doing the same, carb to efi, mani design not compatible with space. Have a look at whether gaskets are all shared on NZ gaskets. Believe they are within years of manufacture. Quote Link to comment Share on other sites More sharing options...
ThePog Posted November 7, 2016 Author Share Posted November 7, 2016 It is very tight under the engine cover. The other option is getting a Weber to replace the factory carb.. Quote Link to comment Share on other sites More sharing options...
HighLUX Posted November 7, 2016 Share Posted November 7, 2016 Only thing thats different between Y series engines is slightly different port size on the heads AFAIK/mine is a 3y block and the head is stamped 4y so yeah shit is lego as. Townace retrofit for injection should be easy since it was only the Townace/liteace series of vans that got an injected motor, although with yours being a ute things might be a lil bit tricky since theres the rear panel where as a van would have open space. Iv just gotta make an extension adapter pipe for my van to get the T/B under the seat which for a man of your engineering caliber should be a walk in the park 1 Quote Link to comment Share on other sites More sharing options...

HighLUX Posted November 7, 2016 Share Posted November 7, 2016 Looks like it should fit. Might have to mount the powersteering reservoir somewhere else. The throttlebody should sit at the same height as the hose coming off the carb Quote Link to comment Share on other sites More sharing options...
ThePog Posted November 7, 2016 Author Share Posted November 7, 2016 So what would the deal with the ignition be? Apparently the vac stuff is deeply integrated on some versions... Quote Link to comment Share on other sites More sharing options...
HighLUX Posted November 7, 2016 Share Posted November 7, 2016 To inject it you need loom ecu map sensor distributor thermostat housing thing with the filler cap on it as it has temp sensors for the ecu inlet manifold with injectors fuel rail/all bits etc(obviously) plus exhaust manifold because its likely your carby one is the same as mine and bolts to the carb because they run an EGR valve thing. Gotta link to the gear on trademe? Quote Link to comment Share on other sites More sharing options...

Duncan McKee Posted September 13, 2019 Share Posted September 13, 2019 The answer is to drop in an asian market 4Y. Straight in. Use a Weber carb from Oz and you can jet to suit. Weber comes with a Lynx air filter, fuel line, vacuum line and a wire for the electric choke. That's all. 2Y is 79 hp @ 5000 rpm and 140 nm @3200 whereas 4Y is 95 hp @4400 and 182 nm @3000 Gear up with slightly taller profile tyres. I run 205x60x15x6.5 alloys from a Daihatsu suv. More power and huge increase in torque at around same revs. Result it pulls hard everywhere and with the zero emission control junk sensible fuel economy is restored. 2 Quote Link to comment Share on other sites More sharing options...
ajg193 Posted August 30, 2023 Share Posted August 30, 2023 Anyone know if 3y injection system will run a 4y happily out of the box? Brand new 4y long block out of China is $1000 Quote Link to comment Share on other sites More sharing options...
HighLUX Posted August 30, 2023 Share Posted August 30, 2023 Itl be fine its only a forklift motor 1 Quote Link to comment Share on other sites More sharing options...
