4G63 Discussion

[Okinawa Boy]

This is a forum for those who have an indepth knowledge of 4G63 engines. I've created this forum to gain more knowledge on the differences, similarities, "swap-ability", and engine specs of the eclipses version of the engine and the Lancer Evolution's version of the engine. I have been living in Japan for the last 5-6 years and have been in the Street Race scene here for most of that time. Feel free to share your knowledge. ABSOLUTELY KNOW BASHING IN HERE! THIS FORUM IS NOT FOR THAT! WE'RE ALL ADULTS!

Welcome to the site!!!

Welcome and be a little more specific on what questions you have.

Thank you for the warm welcome. Truly took me by surprise. First, let's start off with the differences between the Lancer's 4G63 and the eclipse. I already know the turbine's were wayyyyy different. What about the internals? Were the pistons different? Where the cams different? The Evolution is rated at 280 (like most Japanese super cars) but really pushes about 320. A friend of mine owns and Evolution IV. And also, could I get a Evolutions computer remapped to work in an eclipse?

 

[L2RTSiAWD]

Evo motor has better pistons than a 2G with 8.7:1 compression. The manifold is a log style with a divider in the collector to support the twin-scroll Turbo. It comes with 510cc injectors and a bigger fuel pump.
You can't get a EVO ECU to work on an eclipse I'm not sure abot the cams but the are probably more aggressive like the 1g's

So. In theory, I should be able to swap the manifolds from one to the other. Correct? I'm thinking that the cams from the EVO should fit right in if the two engines are basically the same blocks. My car was a Silvia Q. I swapped the engines out. The NA parts from my old engine can swap right into my turbo engine. As a matter of fact, when I was changing the engine, the air conditioner compressor, starter, alternator all were interchangable. I know that some people take the cams from the NA engine and use them in the Turbo engine because they're made for high compression. I'm thinking maybe you could do the same with the 4G63.

What about the Airflow censor? Does anyone have a picture of any eclipse engine parts? 2nd Generation that is

 

[L2RTSiAWD]

The engines are reversed in the EVO and the Eclipse so the manifold will not bolt up. I'm not sure which MAS the EVO's use but it's probably like a 2g MAS. The cams may work though.

Ahh... The beauty of knowledge!!!

I didn't know they made eclipse's in Japan!!!

Welcome. Have any pics of that S14?

Well they are made in us but get shipped to japan where they have the tail lights with the amber corners.

Got the solution to the reversed engine problem. The Evo 1,2, and 3's had their engines facing the same way the eclipse has its. They reversed the engine from the Evo 4-7's. I don't know why. By the way, I do have a pic or two of my car. One of them is when I was working on it in the shop. I took my Bomex bumper off because I was putting my front mount intercooler in. Just one problem. How do I attach pics to my messages? I'm new here, as you can see.

 

[L2RTSiAWD]

Right but 4-7 is when the started with the log mainfolds and twin-scroll turbos I have a evo3 manifold for sale right now the evo-1-3 has the manifolds like ours and the Big-16g's as the stock turbo.

I don't know about the Evo 1, 2, and 3's turbo that much. I know the 4-7's all had Mitsubishi made, stock TD05's (also 16g). I'm sure there's a way to custom fit it.

 

[Okinawa Boy]

How do I attach at pic on this forum?

 

[L2RTSiAWD]

Down at the botton of the reply page it says attach file and there you can browse you HD for the pic.

Gotcha! This is a pic of me in Nara. The ancient capitol of Japan. My car is above it. It didn't come out that clear and the bumper was off due to the intercooler being installed

 

[L2RTSiAWD]

The problem of fitting a turbo from the 4-7 is the compressor housing is on the opposite it as our cars and is rotated the worng way so you would need custom IC piping. Also you would not have a log manifold for the twin-scroll turbo so you would need a custom manifold.

Nice pic I love japan and S14 is my favorite silvia

Thanks ! The picture was taken at Todai Temple in Nara. Not too far from Osaka. It was cold that day. As a matter of fact, I was supposed to take a ride in Signal Auto's 1100 hp Skyline GT-R but my Japanese friend (who's a good friend of the owner of Signal) got sick. Poor him and even Poorer me. Oh well. Maybe next January.

As far as my engine goes, Mr. Tawata (the Japanese friend of mine that got sick in Osaka) found it for me. It's a black top block with a red top head. "Huh" is right! I said the same thing at first. Then I found out that alot of people do that here. I paid Roku Man Yen ( at the time 461 dollars) for the engine, wiring harness, computer , mafs, and it had a super single plate clutch already connected to it. I deal parts, so the intercooler, GTR fuel pump, air filter and Z32 air flow sensor were all parts that I already had. You can see those GTR Seats in that picture. They are alot better than those old S14 seats that I had before. Next is going to be that Conversion to an S15 Ichigo face. and R34 GT-R Wheels (they're sooooo expensive...so I'm going to save for them). I'm also going to sell the GT wing that I ordered out of Option Magazine and get a R34 GT-R wing. Police were giving me a problem about mine. I guess that's how it goes in the world of modified sports cars. Nice rides sometimes get negative attention.

Anyhow, back to 4G talk. I think everyone knows my plan. My father owns a 2nd Generation eclipse and I'm thinking of making a turbo kit for it out of various Evolution parts. Thus the reason for this forum. If it works, I'll sell the kits on my website that I'm making.

 

[L2RTSiAWD]

I love skylines also. It sucks you didn't get to ride in the signal skyline. I also think for the money it would cost you the kits would be very expensive and you could get more power for less money. Just too many obstacles when It comes to the 4-7 turbos and manifolds. Had they bolted up People would have already been selling them.

With all the expert welders and body/chop shops you have in the states, I'm sure they can make a custom manifold. I mean, c'mon. The States is the home of the Turbo-charged Civic. No one over here thought of that. If you can get a civic with a turbine on it and it doesn't normally come with one, I'm sure someone can make a manifold and piping for a modified 4G. Innovation is what America is all about

 

[L2RTSiAWD]

Yes if you want to spend 500 dollars on a custom manifold. I'm not saying it can't be done. I'm just saying the cost more than outwieghs the benefits.

Let's say I do work out this math problem and get this to work. The turbine being the key issue here, I'm sure you'll be able to get a max of close to 380-400 hp with a few more upgrades. My friend is already pushing that threshhold right now with his and he has air filter from GReddy, Straight pipe, aftermarket turbo muffler, downpipe, and a g reddy boost controller. Almost forgot his twin plate clutch. So if I can get the turbine to fit with an custom job manifold, my problems will be just about solved.

So how much does a turbo kit cost? One that will put you well over 400hp?

 

[L2RTSiAWD]

Just a the turbo itself that uses a the stock manifold. Anywhere in between 1000-1500 dollars.

P.S. you will also need custom Intercooler Piping.
