ok i have the 420a motor i thinkand i want to know can anybody tell me where to look for the motor casting that tells what block it is and has any body ever seen a 2.0 head with cam gears that say 2.4L on them and is it posible to fit a 2.0 head on a 2.4 block?
thanks

 

If the cam gears say 2.4l on them then it should be a 2.4l head also.. no the 2.0 head will not fit on the 2.4block, the head is too small..

 

so how can i tell which motr it is and my valve cover says 2.0 on it

 

if your valve cover says 2.0and you got no turbo, more than likely you got the best engine ever....the 420A.

 

but thats the thing my vavle cover says 2.0 but my cam gears say 2.4L on them. should the engine be stamp or something somewhere on it?

 

yea, there should be something marked on it, im not sure where on yours, i have a 1st gen, but on mine it is.. ok, standing in front of the car, it is (on mine) on the front right like, under the mopunt almost, there is a little ledge that says what engine mine is, im not sure where it is on the 2nd gen though, but i know it is on there somewhere

 

if you look in your manual, it should tell you. if you dont have one, trust me you'll need it, you can get one for 15 bucks or so from the parts store or cheaper on ebay.

 

dude, 4g63's are 2.0's as well... is your car a spyder? is it possible that it's the 4g64 but with a 4g63 head on it? isnt that a known swap? but then the head and cam gears wouldnt match... so i dunno

 

yeah i gotta pick one up the car didn't come with one. but i drovemy friends97 eclipse rs that had a couple bolt onsbefore and this car had alot more pull and it appears to be stock but i bought it from a guy for $200who got it from a impoud so theres no telling what the story to this car is.

 

i don't think it's the 4g63 cause my battery and transmissionare on the driver side of th engine bay
