SRT4 engines vs 2.5 16V

[nvysion]

Hello,
I must change my daily driver car and was thinking buying a PT cruiser with a 2.4L turbo engine with the idea of using it later in my 89 Shadow.
I live in france and the only chrysler 2.4L engines are found on the Voyager (NA engines) with a lot of kilometers (200 000km to 300 000 km) and PT cruiser (NA and turbo).

So I would like to know what is involved to :
1/ put a 2.4L a 16V head in the 2.5L engine
2/ put a 2.4L NA engine (3/ put a 2.4L turbo engine (change the turbo

1/ requires : timing belts, sprockets, water noses, intake and exhaust manifolds, ... ?
You keep the stock trans and harness.

2/ and 3/ requires : rods, pistons, turbo (bigger ?), intake and exhaust manifolds, new engine supports, ... ?
Can you keep the stock trans ?
Do you need a new engine harness or you can use the old but with some modifications (distributor) ?

What is the easiest way ?
What engine will support the most HP ?

If swaping a SRT4 engines require a few mods I will buy a PT cruiser to use it later in my Shadow.

Is there a real advantage of an 2.4L swap vs a 2.2 or 2.5L engine with a custom intake, big 8V head and an hexhaust header, which I think will be cheaper ?

Thanks

I must change my daily driver car

Why? What's wrong with your current 2.5L now?

Hi Harry,
I'm not sure if my A413 trans is in good shape, but that is not the object of this thread.
I don't use the shadow as a dayly driver, only during the weekend.

I would like to replace my fiat which needs some work with an another car and I was thinking of a turbo pt cruiser with the idea of using the engine later in my shadow
But I will choose this route if only the engine swap is "friendly"

The 16v heads flows better (http://users.erols.com/srweiss/tablehdc.htm#Chrysler) 2.2-8v@.500= 165/123 2.4-16v@500= 234/171

The block is a tougher choice - 2.4 vs 2.2 vs 2.5, and i think electronics (ignition/fuel) is the biggest consideration

it's not to difficult to get 2.4 into the 400's (search and you'll find a bunch of 600-700 dyno runs), it will need a strap kit for high hp, motor mounts.. megasquirt (or head mounted distributor w/chip), don't forget to use the SRT oil pump (more volume), oil cooler w/big filter (extra spacers), arp head & strap -- and the nice to have oil squirters

2.5 will require cam gears, chip, plumbing(blocking oil passageways).. searching around i found a couple 400-500's (http://www.turbo-mopar.com/forums/showthread.php?19093-FWD-Dyno-Cal-2.5L-16V-DOHC-Hybrid)

final note: i haven't made it to the dyno (yet) with by built srt but it is fun running >25lbs & e85

the 2.4 turbo is the easiest and most cost affective way to go 16v. Bolts up to our trans with the exception of 1 bolt. Rbryant makes an adapter. The pass mount is documented as well. Then it's just getting the thing wired up and a cal for it and go.

I see.

I'd go with whatever you can get parts for easier, consider you're in France, that's going a big deciding factor.

Thanks

If I go with the 2.4 turbo :
Can you still use the original harness with a 89 custom ECU ?
How about the trans-axles ?
