LS1 Question

[87OldYeller]

I know it is not directly related to this forum but. What I am tiring to figure out is will a throttle body off of a 2001 5.3 work on a 03 5.3. The Difference between the two is the 01 is cable operated and the 03 is electronic operated. I know the base gasket is the same. so the bolt pattern is the same.

You can switch the throttle bodies.

Thanks. Good to know.

Will it need a new harness and ecm as well? I am curious because the three that I bought have the cable, and after thinking about it, i think the throttle by wire system would be easier to install. Also, not to steal the thread, but I didnt want to start a new onefor one question, but I bought a 4l60e out of an 01 S10. Will I have any problems using it on my 5.3?

[87OldYeller]

the only thing about using the cable throttle body is you will delete the wire's for the electric one. But the cable one is better

[Captkaos]

The cable will be MUCH easier, the drive by wire ECM will work with the cable setup. 
You have to retrofit a pedal assembly into the truck to use the drive by wire.

What motor was in the S10?  It will physically bolt up, Vile can correct me if I am wrong, but I don't think they were built as strong as a comparable trans in a V8.

Thanks Capt, the S10 had the 4.3 in it. I figure it will bolt up, but was just curious if it was the same tranny as the full size pickups, or a weaker version. I got it for $300 with about 60k miles on it. So far Im at $650 for a complete 5.3/4l60e setup.

[Captkaos]

I think the S10 got the "60" version and the fullsize started getting the "65", but you should be ok.  What is it going in Chop?

[choptop]

Its going in my tan 86. I dont want a hotrod, just a good reliable cruiser. I figure if the 305 moves the truck good with 160hp or ?? then, the stock 285 Hp 5.3 should do great.

[Captkaos]

You should be fine.
