Mitsu 2.4 ltr DOHC same as the Dodge Motor

The lancer has a 2.0 SOHC motor, and the Evolution has the old 2.0 DOHC turbo, neither of which are related to the SRT motor in any way.

Mitsubishi does make a 2.4 SOHC engine which comes in the Eclipse, Galant, and Dodge Stratus, but it isn't related to the SRT motor either.

Kyle, the heads are not the same size?

They could very well use the same spark plugs, but if so it is by accident rather than design collaboration.

About once a week someone hits up the Neon boards wanting to either swap in the head or engine from a Mitsu 4G63 into their Neon, and it just isn't feasable. The DOHC Neon, and DOHC Mitsu heads (and engines for that matter) share nothing in common, while the SRT head is an evolution of the old Neon head. You could bolt an SRT head right on a Neon block if it wasn't for one enlarged oil passage.

So, by looking at the current spark plug (Champion), it should fit into the Neon head?

Is this is so, then the Denso Iridium Spark Plugs should work with the SRT-4 heads...

I'd say that is a pretty good assumption.

Ok thanks Kyle, I will purchase some Neon plugs and try them out.

let us know how you make out! 8)

I am checking out the prices: 49.00 for four plugs. :shock: Expensive validation.

BTW Kyle the Stratus motor is not a DSM motor but i will correct you...the Stratus Coupe uses a DSM motor but the Stratus Sedan uses a 420a 2.4 DOHC. :wink: 8)

So isn't the same type as the A8XX series motor (spark plug concern)?

the plugs on the A855 are just down right hideously scary big

Dan, you are saying they are not the same size plugs used in the Stratus engine?

thats a roger

I found part#'s awhile ago for NGK's, but no one though it would be benefical obviously.

The length of the SRT is 26 some odd mm's while the neon/strat are in the 19's in length

Tonight, I will do some cross referencing from the Champion spark plug number to another model or make car.

The SRT head is totaly different than all the other heads out there? I want to port my head and IM thinking of getting a 2.4 head from a chrystler but not sure if its the same.

I would prefer to get a head and port it so i have less down time on my srt.


SRT4 head is unique in that I cant use any other 2.4 head as a swap? Yes/N0?

How about maybe so?!? I was told by Gary Howell that the SRT and PT/Stratus heads are the same, BUT Gary's SRT is a pre-production car so take that for what it is worth. You might want to hit up Bob Stockum and see if he knows for sure, he is the head guru when it comes to all varieties of 2.4 motors. www.bstockum.com

If you do venture to try a PT/Stratus head, make sure it is a '03 since I heard that both the NA and turbo 2.4s have a larger oil drain than the pre '03 heads.

While we are on the subject of heads does anyone know what the SRT valves are made of? Long before the car hit the streets there were some pretty credible rumors floating around that they were going to be made out of Inconel.

I was hoping the older engines used them also, that way i could find them laying around at any engine shop and it would probly have been about $400. If its an 03, i can see $1000 plus.

If you are going to port it why not start with a used one? www.car-part.com It shouldn't be too long before a few '03 PT and Stratus heads start showing up for pretty cheap.
