98 gt wagon motor swap

[dp213]

I have read a lot about the frankenmotor and not sure its the best option. My wagon in an automatic and I have to put a new motor in it. I am starting from scratch and using nothing from my motor as its my daily driver. I don't want to lose any power by going to a 2.2 but I also want to get away from the double cam. Any ideas would be great.

 

Thanks

From your parameters, a frankenmotor build up is your only option, as only a double cam 2.5 (which you now have, and don't want) from 96-99, or a 2.2 motor (which you don't want) from 95-99 will be compatible with your car's OBD2 electronic control system. 

 

From my personal experience, I have a 2.2 motor replacing the 2.5 in my 98 OBW. Yes, it is down a little on power, but still has acceptable performance to me. A stock 2.2 motor is super reliable, and runs smoother then a 2.5.

 

Yes, a frankenmotor will develop more hp, but at the expense of requiring high test fuel, and prolly loosing some reliability. Just be sure to buy the very best head gaskets on building a frankenmotor.

Would those be head gaskets from conetic

I am not a HG expert. Suggest you create a separate thread to ask USMB members their opinions on HGs for a frankenmotor application.

Yes, comtec HG they have one for the franken motor.

 

I would not rule out the 2.2, as they do fine.
