Is my engine a 420a or 4G63??

Sault Ste Marie,
okay, I feel like a total idiot asking this, but I was reading up on engines, and apparently the 420a isnt good at all compared to the 4G63. I know the 420a is chryslers, but on wikipedia (not saying wiki is god or anything) says that the 4G63 is only for the 1997+. and I always thought my 1995 tsi awd eagle talon was 4G63, even says mitsubishi on it. And my next newbie question is.. what is SAFC??

k now that the newbie question is outta the way,
I have a 16g small turbo, 2.5" turbo back exhaust, no cat, turbosmart boost controller, K&N cai. so I know I need fuel upgrades.. rail, pressure reg, pump and injectors..

what should I get, I want a decently fast car, but also very reliable. and i know its bad to have the 16g on already, without fuel upgrades, but i got the boost down, and the car is sitting for now.
 
What N/Ts came with that valve cover?
Any 1990-1994 4G63-powered non-turbo had the same valve cover as other 4G63's.


That's my polished, cracked 4G63 valve cover that I bought from eBay for $7. It's basically a wall-hanger because it's cracked...it's a shame that someone put so much time into polishing it to a mirror finish and have it crack. The seller actually listed it as an uncracked valve cover, but I knew where to look as soon as it was in my possession. I immediately contacted him, and he agreed to give me a full refund minus the $7 shipping costs, and allowed me to keep the cover because it wasn't going to do him any good.

I set the polished 4G63 valve cover on my 420A and snapped a pic, and titled it "The only way a 420A will ever make serious power." There's no way in hell it would ever actually fit...but the photo makes for a fun conversation piece.


Can't you use a turbo head on an n/t?
You can use any turbo 4G63 head on a 1G non-turbo with a 4G63. The turbo 4G63 head will not fit a 2G non-turbo with the 420A engine.
 
In regards to the valve cover posts above by BulletShiftTSi....I snapped this pic while recently changing the valve cover gasket on my 420A; I thought you guys would enjoy it. Surprisingly, it confuses the sh!t out of people who only give it a quick glance:

what i wanna know is where is your coil pack that usually mounts in the middle of the original 420a's VC? or do you just have it off right now.. and how does that cover fit with the cam gears being on the opposite side?

good jooke but the cams gears give it away that its a 420A... the 4g63 valve colver has the two lifts only on the driver side of the engine due to where the timing belt location of a 4g63.... and you can tell that the bolts dont line up as the driver side poetion of the head is exposed..

i almost thought that would fit the 420a damn.. well it was a good joke!
 
Not to get completely off topic but the cam gears and belts being on the oppisite side do give it away also the battery is in the wrong place, the intake mani is completely different and 180 oppisite direction and the upper radiator pipe isn't on the left side of the motor like its supposed to, there is no turbo or piping on the car, and the throttle cable is in the wrong spot, and the cover doesn't cover the whole head.

But I will be completely honest in saying that By just a quick glance I thought I was a 4G63 then I thought It was a 420a with a 4G63 cover on it and my eyes popped out of my head thinking thats impossible. then after futher looking I realize you the pic tricked me like everyone else before me and I discovered all the above mentioned differences.

looks cool tho!

p.s. sorry for the semi thread jack!

(Are you getting the realization that there are some people who come on here, then plain WON'T listen to what the lot of us are trying to say - with us all trying to help SINCE we have the vehicles in hand and work on the danged things ??)

Who are you talking to?
 
Wow why would this thread need 40 posts... there was so much wrong information i was getting mad reading it LOL... Europeans N/T 2gs came with 4g63s that did not have a turbo. So not all n/t 2gs came with 420a's. All dsms have aluminum heads. 2g 7bolts can handle 400hp, I have seen one do it and the reason for failing was not CW it was the rods bending... It is less than 20% of 2gs get CW and it rarely happens after 90k. 4g64 came in spyders as well as the 4g63t. If you do not know for a fact or with out doubt that what you are saying is true then dont say and we honestly did not need the community letting this guy know what a safc is and he had a 4g63... Come on now...
 
Now, wouldn't it be a bit fun if the Spyder owners took that 4G64 out and put in a 4G69 - the motor in the newer Eclipses....25 more hp stock and that uses that variable valve timing?

because the 4G69 faces the wrong way like a 420a
 
any 95-99 n/t DSM comes with the 420A only 90-94 came with the n/t 4g63 90-92 came with a 6bolt 4g63 and all turbo dsm from late 92-99 came with 7bolt 4g63's

You too my dear boy are wrong as well...:ohdamn:
2g euros came with n/t 4g63
