engine replacment, 3s vs 5s Options

[Vissi]

Seeing as how my engine is at about 170k miles now and i think he valve stems are going bad im looking into getting a new engine. All the quotes on th valve seals were about 1.2k, and id rather just put that towards a new engine.
If i had a place and time to do the swap i would go with a 3s for sure, but i gotta have a car to drive cause my celi is my only car.

I was wanting to know the price of labor at a shop doing either a direct 5s to 5s swap, or how much it would be for the 3s.
I would eventually turbo the 5s,i just know its a lost cause on the one i have now.
thanks for any info

I just got a new job, so i can finally afford nice stuff

valve stems or valve seals? valve stems you need new valves, and the head will have to come off. valve seals you can do yourself with the head on. using Toyo Tool. alot cheaper than 1.2k i bet like 1k off that price tag.

Im sure this engine will last another year, but i don't like turning on my car in a parkin lot and smoke comming out, kinda makes it look like a pos.

Im sure exactly sure what it is, but as soon as i turn on the car, like half the time, it will puff out a huge cloud, and then stop after like 5 seconds. A shop told me it was valve seals, but that was a few months ago, so i may have the words twisted a bit.

What all tools would i need for the swap? I figured id need a cherry picker, i got a descent like 150 piece tool kit, and a craftsman torque wrench.

95celgt, how much for the harness? So basically i just have to have doc tweak mod it, and then there is a plug to the engine harness?

iv been swinging in between which engine for like 3 months, and im trying to figure out how much money and stuff i need to get.
thanks
