Hey Sy-guy is it possible to also bolt up the fuel injection system they use on the SY/Ty on the newer 4.3 if your using the intake man.? I just wanted to know because the Sy/Ty looks sweet with a fuel injector for each cylinder.
Yes it is possible, but do you have the wireing harness? If not then it is a pain in the ass! You will have better performance if you do the regular 4.3 upgrades that everyone else does. Alot of people think it is easy to convert a 4.3 to a Sy/Ty but there is alot more involved than you realize. Stick with your motor and build the **** out of it. You'll be alot happier in the end.
I am using 1 1/2" Billet spacers on the rear and nothing on the front. They are all 17x8 with 50mm back spacing. I didn't go with the 17 fronts and 18 rears because Sy/Ty's are all wheel drive so the wheel tire combo needs to be same diameter all the way around. There is another guy on this board, his truck is in the new gallery, that has a first gen. s-10 that is running the 17's and 18's and it looks sweet. I'm not sure what size spacers he's running though. May want to cantact him. Here is the link to his truck:
Sy/Ty Fuel Injections is PFI 1 injector per cylinder. the manifold upper and lower would bolt to 95 and down heads. What type of injection do you have if you want to convert to turbo that might be the way to go. What injection do you have? CPI or TBI? for the cost of a swap to that injection set up could be costly and then you would have to deal with the ECM it would need to be programed. Maybe a well designed intake and a holly or BB chevy TBI with 2 inch bores would be the way to go
It would be easyier to buy a Typhoon and probably cheaper. Your block has too high of a compression ratio so you would need new pistions, etc... Build your TBI setup to run about 250hp and you will be surprised at how good it runs
yea i wish i could buy a Sy or a Ty those are some bad a** trucks, i've never even seen one personally, but i've seen pics and time charts on them and they are awsome, if i was to see one and it looked in good condition, i would throw down my title right there for it. if it was possible i would buy just the whole engine, but like i've said i've never seen one.:headbang:
