Isn't this Tread like real old????

So why are people still posting to this?
**** life went on man!!!

I can't really tell which engine you are talking about.

if you are talking about the 4cyl engine, then no, 5psi won't get you 300whp. but the engine is great for a turbo. 13psi will put you around 300whp.

if you are talking about the V6, then no, the engine isn't great for turboing. the pistons suck. 8psi will put you around 300whp

I recently bought a 2001 GS that already has 100k miles on it. I was wondering if I should waste time buying new parts to replace all of the old rusted ones in the engine. (The guy who owned it before me did not take very good care of the engine) Or should I just go ahead and swap for another 4g64 engine with fewer miles from a salvage yard and then buy a turbo kit for it, or just get a 4g63 engine like I have been wanting.

I have a question that Ive kinda guessed myself can an engine from a 3000 gt be fitted into an eclipse GT the blocks are the same but the sit opposite so im guessing no on that. But my question is can i incorperate the twin turbos from the 3000 gt vr4 and use them on the eclipse posibly by using the manifolds and turbo set up off the 3000 gt and switch them around to the eclipse? and also does anyone know if the 6G from the 3000GT spins clockwise or counter clockwise ?

whould you have to get rods if you put the evo head on

I realize this is an old thread, but if you guys want info on the DOHC swap, or the AWD converstion please feel free to pm me

so an evo 7 engine will fit in my 2001 eclipse gs. and my engine is called a 4g63

i think your engine is something different i think the 4g74 not sure the 4g63 is for the 1g and 2g eclipse.correct me if i'm wrong.

MOVE ON DANG, THIS IS DEAD ALREADY

i know i might catch a lot of s#it for asking this, but does anyone know if the lancer motor will fit in a mirage that has the 1.5L motor? will it bolt right up to the stock engine mounts like the evo 3-7 motor does to the 3G rs/gs eclipse?

since i have learned that the 4g63 exhaust manifold meets to the 4g64 head. i found out that you can buy the turbo kits meant for the 1G/2G eclipse with the 4G63 motor, and the EVO 3-7 with the 4G63 motor. you have to use the universal piping system so you can customize the intercooler piping, but it will work the same. i am looking into a lot of the modifications for the fuel system also, but it looks as if the fuel rail meant for the 4G63 head also fits to the 4G64 head.

anyone looking for pricing a turbo kit for a 3G Eclipse RS/GS or even a 2G/1G can look up my topic post about the "cheap T3 turbo i saw on E-bay"

well my friend is looking into doing a swap he has a 02 gt and I was wondering if a 91 3000gt 6G72tt would pit or would it take a lot of mods

so what about the ecu? is there anything that you have to do to the ecu to get the evo turbo head swap to work and will a evo 8 head work?

No your engine is a 4g64. the 4g63 went into the 1g GS and GST and GSX and the 2g GST and GSX but was a 4g63t. The 2g 2.4L is the 4g64. Read the first part before you go asking a question that's already been answered.

Did you not read the beginning of the post? only the Evo 4-7 head will fit the 3g's 4g64. None of the other ones. Learn to read before you ask a pointless question.

well seeing as how Ryan-s never mentioned it. it is not a pointless question. you can take the head off of any 4G63t motor and fit it on the 4G64 block. you have to plug a couple holes and get a custom head gasket made. since neither of the motors have been redesigned, except for maybe internal components replaced for better parts. they have continued to be essentially the same engine for as long as they have been produced. one has more displacement than the other, but the blocks are the same sizes and the different heads bolt together to the different blocks. i'm not sure anyone would want to do a swap from DOHC to SOHC, but it should be possible? i hope no one tries it, but it should be feasible.

when speaking in terms of opposite orientation he mentioned that the engines still ran the same direction as our engines. this is why opposite orientation does not apply to head swaps. engine swaps it does, because the transmissions will not swap over, and the other transmissions will no bolt on.

remember though, the 3G eclipse does not have a locking, or limited slip differential. so if you swap for a evo head, slap on a turbo, and boost it up to 15psi. your looking at one heck of a burnout competition car, but your not going to win vary many races with that setup. also i would suggest you look into upgrading your suspension to components that have extreme adjustment parameters, and buying some high grade rubber. if you do not, your just going to slip and slide everywhere whenever you push on that accelerator pedal. yeah i have a 450HP eclipse that can't beat a stock geo prism because i can't push on my pedal to hard or i will just spin my tires!!!

Ok one thing that I might be wrong on but, if opposite orientation doesn't matter, then why in the world does he mention it in this post which is about a head swap? That's the only thing that doesn't make sense to me. Because if it didn't matter in a head swap then why would he take the time to include that in his post?

bfore anybody starts in on me i'm not trying to tick anybody off, or call anybody names. i did not want to pick at this post, but it looks as if some people just can't seem to grasp the concept. below i have colored what i input to better explain this so people can quit asking questions about it, and others can quit pretending, and know, what RyanS was saying. also i believe his post was meant for more modification experienced minds. so if you can't understand it after this i suggest you either PM eclipsed4utoo, or rob, or EMC 3000GT, or bobthecow and ask them about it on a more full scale, as they are all, or at least have been at one point in time, moderators.

(please forgive me eclipsed4utoo, and RyanS)

[quote=RyanS]I thought this would help clear up almost ALL engine swap questions like: "Can I put a GT engine in my RS/GS" or "Can I put a 2G turbo engine into my RS/GS." etc...
Just to get this cleared up ONE MORE TIME (I'm getting sick of typing this) -[U] the 1G or 2G motor will NOT fit within the 3G[/U]. No No No. The EVO motor WILL because it's rotated 180 degrees from the 2G motor's orientation. But they're essentially the same motor..
[I]remember that also the reason the 1G/2G eclipse motor will not fit in a 3G is because the transmissions will not swap over, and the opposite transmissions will not bolt to the other engine. the transmission bolt holes on the eclipse 4G63t is different from the 4G64, and vise versa. [/I]

:gunsmilie:
[FONT=Courier]below is in accordance with engine swaps not head swaps

Here's how it works for people who dont know:
1G Motor - 4G63 Engine Code (opposite orientation from our cars)
2G Motor - 4G63 Engine Code (opposite orientation from our cars)
NON-turbo DSM Motor - 420A Engine Code (SAME orientation as our cars but nothing else is similar - it's a Neon motor)
2G NT Spyder - 4G64 Engine Code (opposite orientation from our cars)
EVO 1-3 Motor - 4G63 Engine Code (opposite orientation from our cars)
EVO 4-7 Motor - 4G63 Engine Code (SAME orientation as our cars)
RS/GS Motor - 4G64 Engine Code
GT Motor - 6G72 Engine Code (will NOT fit any of the above engines)
:57:
Wait.. so whats this orientation thing? *WHY* were things switched? Well.. its more about the transmission than the motor actually. See, nearly every FWD car out there has their motor located on the right-side (like ours) - but during the 90s Honda and Mitsu had their's on the LEFT. Now, this causes a few issues - follow me here: if a motor spins clockwise it'll then spin the input shaft of the tranny clockwise, which then makes the output shaft spin counter-clockwise, which then makes the differential spin clockwise (spinning the wheels clockwise as well). Got it? read that again and connect the dots if you're confused.
:grouphug:
Ok, so whats that mean? Well.. when the motor is on the right side (like ours), that gives you the regular 5-speeds forward and 1-reverse gear. Cool. But when the motor is on the LEFT side (like the 1G/2Gs & early-EVOs), this gives you 5-speeds reverse and 1-speed forward.... not very pratical.
;)
So Honda solved this "slight" problem by spinning the motor counter-clockwise from the start. DONE, problem solved. But Mitsubishi instead added an extra shaft to flip the rotation one more time to keep things going the right way. Ahh... extra shaft... more friction, power robbing efficiency, takes up space - great idea.
:nahrung034:
So this all changed when Mitsu wanted to upgrade the EVO 4's tranny with big ol' gears there just wasnt enough room. So Mitsu moved the engine to the right-side, and decided to do the same for future cars like ours. Ta-da!
:trophy:
Great.. so now we know why the switched orientation - what about the swap? Well, since the 4G64 motor (RS/GS) and the 4G63 blocks are nearly identical, that means that the motor mounts are the same. Hence why an EVO 4-7 engine will drop-in a RS/GS. The RS/GS Starter gets in the way for the EVO Exhaust manifold tho. GT's are a no-go.. they're entirely different and will have more luck swapping in a rotated 6G7? motor.

Anyway, so Mike W said that I had "first dibs" on the EVO motor swap because I've been talking about this for so long (we're going onto well over 2 years that I've been repeating myself here). He gave the incredible price of $6,500 for the full-swap but he got to keep the RS/GS motor to play with. Some poeple were looking into doing an AWD conversion for a long time as well and Mike gave the quote of $10,000 for the EVO motor + EVO AWD tranny swap. Yikes.

[B](4G63t no matter the orientation of the engine they have the same heads on them if i rotate this arrow < 180 degrees it looks like this > the same thing will apply with engine heads why does this not make any sense to you? below is the mentioning about head swaps not engine swaps!!!! and there are 1G/2G eclipse tuners that have bought the evo 4-7 heads and put them on their blocks. opposite orientation of the same motor but the heads still bolt right on. ).[/B]
:) :P
Why didn't I do the swap if I've been talking about this for so long? Here's why: like I said before, the 4G63 and 4G64 are nearly indentical. The 4G64 is taller - with a 6mm higher deck height - and the cylinder bores are wider - with an 86.5mm bore. Other than that, THEY ARE THE SAME. What's missing? THE HEAD. But guess what? I'm almost 99% sure that the EVO 4-7 head will bolt directly to the 4G64 block - plug a few holes, add the camgears and timing belt, and BOOM you've not only got yourself essentially an EVO motor - you've got yourself a STROKED EVO MOTOR. Strap-on a turbo setup and you're packing essentially the same setup as you would with the EVO swap but for half the price (note: before any engineer-types kill me, the EVO motor would allow for higher revving but has less displacement - a loooong discussion for another thread).
:trophy: :trophy: :trophy:
i understand your confusion as he never mentioned whether or not there is a difference between the 1989-1999 4G63T head, the 4G63t motors on the 1-3 EVO, the motors on the 4-9 motor, the 2000-2005 4G64, and the pre-2000 year 4G64 motors. i suspected there is not except for the obvious that has already been stated above, but essentially the same. the only difference between the EVO III and the EVO IV other than the performance modifications was the orientation of the engine. if you blow up a head on a EVO 5 and need a new one the EVO 1-9 heads are interchangeable don't believe me ask a salvage yard. they have a computer program that lists all the available interchangeable parts.
:gunsmilie:
How am I nearly 99% sure that the head-swap will work? Because DSMs are doing this right now as we speak, they're using a pre-95 Galant 4G64 block and bolting their 4G63 DOHC on. They've already got the head and need the block+internals. We've already got the block+internals but need the head.. got it?
;)
Great! So why havent I done this yet? One problem: MONEY. Right now importing in EVO parts (especially their DOHC setup) is f'ing expensive. We're talking ~$1500 for a bare head alone. That doesnt include all the DOHC doodads and I just dont have the cash for it yet. To give credit where credit is due, VAISAYUS was the first to start this project - but its still pretty pricey even for him. [/quote]

Yea but even in that entire quote he still says that he's 99% sure that an evo 4-7 head will bolt directly to our 4g64 engines. If they were all interchangeable I think he would have said that he was 99% sure that the 4g63 head meaning 1g 4g63 and 4g63t and 2g 4g63 and the evo 1-10 will bolt directly to the 4g64 instead of just the evo 4-7.

That's where I get what I do out of that post. So you can see why I think what I do.

well i'm looking into it more myself. i'm trying to find a 4G63t head thats cracked or blown so i can at least see if the heads will match without turning the head around. i'll switch the cams and see if they run the proper intake and exhaust valves when its turning, then see if the coolant holes line up. then i will find out what coolant holes need to be plugged up. if anyone knows a member with a blown 4G63t head thats willing to offer one for this it will help out everyone, i'll even pay the shipping for it, and once i'm finished i will ship it back if they wish to have it back.

i've got so sick of the answers i have seen online about the whole thing, so i'm just going to find out the procedure for myself. this is going to take me a while if i have to find my own head, since extra cash is very low for me it will be like 6-8 months before i can even think about it. eventually all questions will be answered about this type of switch. i will post pictures up of doing it all, and step by step procedures of what and why i do whatever it is i end up doing, so in about 6-8 months all this crap will be done and over with. i have to do piston rings in my car anyways, i came to find out during my smog test my oil pressure is screwed up and its causing my oil to push through my top two oil lines on my valve cover more than usual. i'm not sure what i did recently to have this happen but i'm now running through about a quart of oil in 3 fill ups which is a month and a half.

Will 1G/2G turbo parts fit a 3G GT or just th GS?
