I'd put the intake and exhaust manny onto your new yorker if the head on the yorker is good. Then convert your current turbo to T2 specs and update the electronics to run the newer intake and injectors properly. check out www.thedodgegarage.com for more info on the turbo upgrades. Getting the car to T2 specs will make it much much faster. You can't run the newer style intake setup without updating the rest of the car. It won't run properly.

Heres a list of parts I have coming
90 Dodge Daytona/Chrysler Lebaron with a 2.5 Turbo 1 motor
HEAD, INTAKE MANIFOLD, EXHAUST MANIFOLD, TURBO(which spooled up excellent), FUEL INJECTORS, FUEL RAIL, VACUUM LINES ON THE INTAKE MANIFOLD, AND THE UPPER WIRING HARNESS FROM THE INJECTORS TO PASSENGER SIDE CONNECTER

The intercooler stuff my friend can handle. I know I need a PCM off a 2.5 TI intercooled car. Im going to look but its going to be tuff. Not really worried.

Anything else?

Keep your current head if it's good. The 2.5 head has cross-drilled cooling passages. Just bolt the manifolds onto your current setup/motor. Since it's an auto you can pull the whole motor and leave the tranny in the car easily. I'd convert your current turbo to turbo 2 specs by getting T2 housings for it. It will flow better and with exhaust mods will spool just as quickly as the one that's on the 2.5 head.
Vacuum line will need to be redone, easy to do. Use your wiring harness one the 2.5 injectors.
For the computer you have a couple options. Upgrade to 1987 T2 electronics and have someone (vendor/or someone that can tune the computer code) make you a Logic module that will run it. Or keep an eye out at the J-yard for a 1988 Turbo New yorker, Grab it's wiring harness from the firewall to the front of the car and plug it into your firewall connector. Then you'll need a PCM from an 1989 2.5 T1 car. Add the i/c and you're good to go.

Thanks for helping out!

1)I will check my head. I read that the 2.5 gain some tq down low is that about right?

2)So when im all done. Will this make my mpg computer not fuctional?

3)If I go with the 2.5 im guessing the mpg will be the same. Im getting 27mpg at 65mph.

4)Right now the new yorker hits a wall at 65mph. Now the limit in ND is 75mph. Whats the best way to sharper that up 2.5 head?
