vegas, thanks for your help, but i cant afford that right now, atleast not the new intake and tune on top of the head price, so im proboly just gonna end up running a ported 2.0 head. and put the intake money towards maintenance parts like water pump, fuel filter, timing chain guides thermostat, and a belt...< atleast thats the list soo far. if you guys wanna add anything, let me know.

I'd be figuring out the c/r of the two. What is the difference in the 2 head gasket's? I'm sure the head bolts are the same, but check. Ask Vega's what he used & did. Also since your there I add a set of mild cams= stage 1's. I installed a set of crane's= made a difference.

i put a whole 2.3L engine in car, However the head is same.. Intake bolts right up. To be honest I cannot see porting heads on a 2.0L doing much of anything. reason to port a head is for making more power with more air flow but so much is restrictive, mainly with turbo or something like that where the benefits of smooth is needed for air speed, your not going to do anything in way of making more power if you are just porting your heads.

here is a good tech post on it..

http://www.popularhotrodding.com/eng...g/viewall.html

with our engines and no tune or other advances your looking at what, 2 or 3 hp? you might gain more out of swapping your plugs our for AR-103s or something more simple.

if you just wanna kill time or have more planned by all means head down the yellow brick road.


I think your better off saving your $ and just getting something more. Even if you have a guy to do the work free, a port and polish needs a new valves to be done right , the Valves and other items will still cost $200+ when done or more.

Installing the 23 is the best way to go. Add a 23 head is the 2nd best way. The 23 head flows better than a 20.

yea, without the larger pistons and longer stroke that a 2.3L provides doing a 2.3L head is a far cry from a entire 2.3L engine as far as power.. I would do all the upgrades that would make a trip to a 2.3L engine more enhanced.

It'd be great if you add a 23 manifold w/ a 23 head & get the imtv to work on a 20 car. You'd need the pcm from a 23 car & if your there, I'd install the 23 motor too. I'd be figuring out the costs involved= the head, I/M & the pcm vs the whole 23 motor. The grunt vs the cost. Do a BSD plug & that gets you more & holds more oil too. Say if the head/manifold & pcm is say 800. & for a little more say 500. gets you a 23= Thats what I be doing then. Add a set of mild cams, add a bsd plug, header & tune to start w/ & then your wondering= I come I didn't do this before?

is the gasket on the oil pan of the 2.3L reusable when you do the BSD or is it silicone/cork? or need a new rubber? I have not done mine yet, but found a dirt cheap BSD on ebay... Just $27.50
