Engine Rebuild

[SharpShooter34]

If my plans go right I'm going to get my hands on a 91 AWD Talon that has a "blown engine." I use the "" because I have not seen the car. The individual says the block and head should be good but will probably need a basic rebuild. What basic means I'm not sure. I just want to know what the cheapest way to do a rebuild to a stock engine...no oversized or forged pistons...just a rebuild. Forget the basic part, I'm considering worst case scenario. Would it be cheaper to get a rebuild kit from:

Mach V (even though I've heard the top line brand is not "top line"
Green Bay Parts

or should I buy the gaskets and other supplies from the dealer. I'm just looking for options. I've read other posts and most people replied that forged pistons and extensive machine work should be done. I just want to get the car running back to stock form. In truth I'm just hoping that he blew the head gasket between cylinders and that's causing the car not to start. It's a DSM though, so all I can do is hope Let me know and I'll try to get some more info to diagnose what is wrong. Thanks for your help in advanced.

Get 95-99 pistons from turbotrix.com
Use your stock crank and rods, you have what are know as "1g big rods" in your 91 motor.
The pistons will cost around 2-300 I think, then you just have to have them machined at a shop to fit your 1g big rods. Make sure you get .020 over pistons and get the block bored.
Then its onto your head, I believe a stock rebuild costs around $200.
So ~$500+any machining costs if you do the labor yourself. And you will have a motor that can handle up to 500hp with proper tuning/mods.

How much does a stock block have to be bored to handle 2G pistons? is it a .020 over bore? Thanks.

Just tell them what size you want and they'll get it for you.

An engine rebuild does not just consist of new pistons and that's it.

There are many reasons why that motor died: from spinning a bearing, to timing belt failure, to broken ringlands.

The first thing you need to do is take the motor apart and have someone that knows look at the motor and determine the cause of it's death. I would recommend a local machine shop if you want to save money, but BJ's, Buschur, Magnus, etc...They would do the best job.

Even if your motor just needs a "basic rebuild" it's not just pistons. New Bearings, Rings, Timing belt, Balance shaft belt (unless you are removing the Balance shafts), Timing belt tensioner, New oilpump, waterpump, tensioner pulleys, Headgasket along with all the gaskets, main seal, remove and replace the freeze plugs, etc...

Along with motor work as in: Re-hone, deck, magnaflux, balanced and check all the clearances.

Headwork would be (at least) to re-surface it, check the valves, seats, and replace the lifters.

To me that is a basic rebuild. Remember you are talking about a motor that is 12 years old and is not currently running.

Oh and about the 2g pistons: I am using that setup in my and very happy with it. You can order the pistons in the overbore that your machine shop will determine for your block. But if i were to do it all over again instead of spending $300 for pistons plus $100 for machining them to my rods. I would buy Ross pistons for $400 and not need any machine work.

Good Luck.
