I had a SOHC neon.. Orientation of the engine is correct, however the intake manifold is towards the front, and the exhaust is to the rear on the 420a, the DOHC 420a is apparently very similar, which makes sense, since the 420a is a derivative design the mitsubishi engine.

its a decent motor, I was running in the 13's with mild modifications normally aspirated and an automatic tranny..

However I would look closer at the 4G63 (Evo engine) swap, using the third gen eclipse 4G94 transmission this would likely result in a much easier swap.

Don't get me wrong, none of these swaps is "bolt in" you have wiring, and ECU mods to take into account, but the last thing I mentioned shares many more common components and wiring that would make it a little easier for you.

 

None whatsoever. Any 6g7x motor w/ +3.x liters and up will not fit. Too big.

The 5g mirages had 6a12 and 6a13 = 2.0 and 2.5 liter v6 . . . small displacement blocks.

Thanks for the picture on the 420a block . . . I always can't remember the t-belt orientation.

IMO, I'm think the 420a will have the same/similar mount locations as the DSM counterparts w/ a g63T. That's why the motor is backward facing toward the firewall. Also, it's very rare for NT eclipses swapping for DSM motors. Don't know the ease, just not cost effiecient amongst the school of thought for 2g DSM'ers.

If you're going to look at the 420a . . . good look for the rare 2g Neon R/T w/ DOHC.

Other than that: I know amongst the 1 and 2g 420a . . . they have a terrible cyl head design and will leak coolant eventually like the starion w/ another motor design.

 

^--yea I had problems with my 420a leaking at the cyl head. Also a weird oil leak from the right side of the engine block where there was a sensor. It was a poor design. The trans went out on my car. So I replaced the trans and sold it. Then not even 50 miles on the BRAND NEW trans, the thing went out again. It had to so with some slip differential pin that is really weak in that trans breaking and cracking the transmission casing causing all the fluid to leak out.
The easiest thing to do with those 1g 2g eclipse/talons though was just swap the motor/harness/ecu/trans with the 4g63t motor in the GST model eclipse.

 

Is there enough room to shove a turbo in there if i swap a 4g64 engine into my lancer?

 

seeing a worthless swap thread= pricless.... buy an rrm turbo they go for 4 grand and youll run good power///

 

^---haha yea, turbo would be the best way to go. So true.

 

How much HP do you get for 4 grand?

 

200 whp... plus options to be able to ahcieve about 250 pretty easily with stage 2 and other mods... ull run 13-14s

 

Let's see less chit-chat and more swip-swap!

 

Which brings me back to checking with Illuminati on his 4G63 swap..

 

That guy has his own thread.

 

Damn, he was open for that one.
