How to tell a 4g63

[Extremities]

I'm asking the forever long question. I've done my research and I've seen so many different answers. I'm confused.

What Eclipse models came with the 4g63 and how can you tell if thats what you have? People have said that the 4g63 intake is on the passenger side and the 420a is on the driver side. I've also seen that you can tell by the valve cover. I had a 98 spyder gs that I just got rid of and the intake was on the passenger side but I was told it was a 420a. Did the 4g63 come in a gs as non turbo or do I have to shell out the extra money for a gst?

I'm not asking about swapping, I already know that headache, just how to tell the difference and which models it came in.

You are a bit backwards.

4g63
Timing belt is on the driver side.
Intake is towards the firewall
1g the NT cars were 4g63
2g Turbo cars came with the 4g

420A
Timing belt on the passenger side
2g Non turbo cars came with this engine.
Coil pack is bolted to the VC

Second gens go like so:

RS, GS: Chrysler 420a engine
GS Spyder: 4g64 engine (non-turbo)
GS-T, GS-T Spyder, GS-X: 4g63 turbo.

The 4g63 and 4g64 have similar layouts, the 420a is "backwards" compared to the 4g's.

Ok, that pretty much clears it all up. So I am going to have to spend the extra money for a gst. Thanks guys.

If you can try to save up for a "gsx" AWD model
They tend to go for around 4k

ughh id love to get a gst or gsx but none around my area so far been looking tho.

Rocker cover kind of gives it away.

One will say "Mitsubishi" on it.

The other one won't - Just "DOHC" is stamped on the 420A cover.

Mitsubishi Sirius engine - Wikipedia, the free encyclopedia

this will give u a list of all cars that came with that engine and info on the engine.

My talon valve cover doesn't say mitsubishi but you can clearley tell the difference between the two engines not sure why this thread exists

I spent 3k on my 1g GS .... At least the body and interior is in good shape..

I believe only the auto Spyders came with the 4G64, and it was a SOHC engine that doesn't really look like the turbo engines.

I like the pictures but you need a pic of the 1.8 also

And a tacky cut air-can. This is not my other car, but a pict I snitched off another site. I wouldn't be caught dead with that "spiderweb" of add-on wiring under the hood. That's asking for an fire to happen. But, the 4G37 is a very simple motor to work on .. doing belts where a 8yr old can do one on these things.

This motor can run forever if taken care of.

Owners have mentioned of over 400K miles on these things before it's time for just a simple ring and bearing job.

..and, its a motor that can be turboed quite easily with custom manifolds, 450 injectors (stock for these things are 240's), "Wally" 190, ECMLink, double head gaskets to lower compression, et.al. Nice thing is that these motors are long stroke motors, making them good as rally motors if someone wanted to turbo this motor. Reports that with the right conversion, almost 300BHP can come out of this little 1.8L where stock it's only 92hp.

No, every Spyder GS came with the 4g64 SOHC engine. Manual and Auto. The valve cover is very different, but a quick glance around the engine bay shows just how similar they are to the 4g63 layout. The DOHC head will even bolt right on, which makes the engine look like a NT 4g63. (see pic)

OP- Hate to say it, but you sold a diamond in the rough. The 4g64 is a very strong and reliable engine in stock form. With an AWD and DOHC swap, along with a decent turbo setup and turbo ECU, you have a convertible that an equally modded hardtop can't touch.
