help im looking for a sweet race engine for my 98 eclipse gs turbo...being that its ass backwards from the gst and gsx engines i cant find a nice race engine that isnt a 4g63...i heard that an evo engine actually fits my car...is this true or just someone with the wrong news...if its not true where can i get a sweet engine...thanks

It wouldn't be a simple swap. The evo engine is mounted the other way around; timing belt on passenger side, tranny on the drivers side. I'm also not sure how the ECU would like that engine in there as everything is back to front.

evo engine is a 4g63 no0b.

ill assume youre talking about a evo 8. for the amount of work involved, you might as well just get a 90-99 dsm 4g63. theres a few threads on this, you will find them if you search.

I think the kid realizes that the EVO is a 4G63 based engine. He also realizes that it is orientated like his 420A. Right? The whole basis for his question. Who's the noob?

This has been pondered by some and "bench built" by those who don't know. But if you've got the money and some time, why not?

Logic: Electronics would be the most difficult. How does the EVO compare to the standard 4G63T for electronics? Same/similiar sensors? How about going from a 420A to a 4G63? Same/simliar sensors? What about the ECU? Will the ECU of a 4G63 car plug in place of a 420A car? (ie. do they have somewhat similar connectors)

As for the engine itself. It packages similiar to the 420A. Is the bolt pattern for a 420A trans the same as that for a 4G63? How about the dimensions for the block to flywheel? Those would be critical for bolting the EVO to the 420a tranny.

Engine mounts? How could it be any worse than putting a 6 bolt in a 2G? There's some fabrication there. This may just need a few more mounts modified. Front/rear engine mount and the pass-side mount. Tranny mount should be the same.

I speculate it could work. Just be prepared to have some down time making mounts and hooking up electronics.

Yea and alot of money!



The price tag and work involved does not justfy what you end up with. Save your self from the headakes and just build a 90-92 6bolt

It would cost less. and Stock for stock, the evo 4G63 can make what like 50-80more HP before rods start brakeing...

If your going to go though this much work its not for a street/strip car, you could build a 90 like I said to hold say 600hp reliably probly as cheap as trying to do that. And not be as much of a pain in the ass.

EXACTLY! Thanks for understanding my question...i figured itd be a hard swap but itd be cool if it worked...thanks for ur input though il keep it in mind before i start spending to much time and money..thanks

It might not be all that hard.I was thinking of doing this with my 2g nt with a blown engine.I have seen places on the net( but I can't rembere where) that sell the evo engine with ecu tranney and harness.If you got one of thse it might work.It would require gutting the engine bay and making sure that the center crossmember for the front and rear engine mounts is in the right palce.If it is it might just drop in, and you can use the evo tranney.I am not completly sure but I think that you can remove the output shaft for the transfer case and make it a FWD car.But I myself have not done it just toyed with the idea, and concluded that it might work.However I decided to just get a 92 TSi and start there.Either way best of luck to you.

Sure it will fit, it fits in no problem. Hell for enough money I'll make a viper motor fit in your engine bay. Is it worth it to goto a Evo engine when you can make all the power you want with no headaches by using a 4G63? No.

Here's the plan. Just sell your car, buy one with a 4G63 and build it. Don't be all attached to your car and not want to get rid of it. I have been there done that and was glad once the old car was gone, trust me. Just sell it and buy what you want, stop trying to frig around with motor swapps and problems etc etc..

you? *shrugs*, i dont know. certainly not me. he made it clear that he DIDNT want a 4g63, then immediately inquired about a evo motor.

whatever..

here's the bottom line: will it fit? yes. however, will a 350 fit? yes. will a 90-99dsm 4g63 motor cost about the same as a evo 8 motor? probably.

thats about as cut and dry as an answer as you can get. why not just sell your car and pick up a turbo car?

- there's a great thread about this somewhere. it was around about a month ago. i cant find it. perhaps someone can with the search option...

just buy a 6 bolt 4g63 an evo III 16g turbo and run 19psi(like the evo8)

good enough of a race engine? id think so.

And EVO III motor would fit and you could proly find it rather cheap...Just look for the motor with yellow injectors, and research the 1g in a 2g swap...510 injectors b16g larger o2 housing!!! That would be the swap you've heard about...Good luck

Evo 1 - 3 engine will fit. Evo 4 onwards the engine is rotated 180 degrees......

i usually dont reply like this but....

this issue has been beat to death. Can a mod lock this thread.

Hey man try to search next time, i guarantee you youll find at least 5 posts about this in the past.

the swap wont be easy...i dont even know if its possible. I know in the 1g turbo awd it can be done, but i cant say ive ever seen it done a 2gnt. I really dont think it would work

Well I guess you haven't researched before you replied either because there several articles on 6 bolt motors in the second gen... He's going to need the wiring harness, ECU, and if the motor mounts from the 420 are different then he'll need those. Engine and tranny, And the shift cables, And don't forget the 2G MAS. It will not be exactly easy but it is very doable...But all together Pretty Expensive!

P.S. Eclipse96Ryder There are several threads on here about Crank walk too maybe you should go flame them too...:thumbdown Oh yeah You don't have a turboed car

Bro, take it from someone who has been and pretty much is in your shoes. If you want to make a lot of power, just trade the car in for a factory turbo model for so many reasons. One of them, no matter what you do, a factory non turbo engine that you have up and throw all kinds of new stuff at will never have the reliability it once had. My 420A is .020 over with H beam rods and 8.5:1 pistons, 440cc injectors, HRC Stage 2, FMU, S AFC, and a whole lot of other crap, at 18 psi it makes a LOT of power to be a neon motor but guess what, it has no traction whatsoever. If I told you my 1/4 mile times, you would laugh. I bought a 1g AWD car and I am 1.3 seconds faster on the stock 14b turbo and SMIC. I am now selling the 2g at a nice loss just because of the uselessness of the power after throwing more than 8k under the hood. If you succeed in the Evo 4g swap, which is possible, you are going to be dissapointed. You will have thrown MASSIVE amounts of money at the car man. The resale on the car "may" be better to a tuner but, the reliability of the car and your comfort to jump in it and drive 1000 miles is gone. The 420A powered DSM has the ENTIRE wiring harness through the ECU. tail lights, headlights, blinkers, so much has to be fabricated for the car to continue to function. There was a semi local guy who did the swap with a 6 bolt motor and it ran less than a week and burnt to the ground from some of the rewiring. Not the mention when you are finally finished if you do not get so burned out yourself from all the money and time, you will have a traction disadvantage. Its so much cheaper to just buy the turbo model if thats what you want. I am so glad I did. Just some friendly advice dude, you can take it or leave but I have been in your shoes.

yeah thanks alot guys for your input...im def not gonna try this swap i was just wondering if it was heard to be successful or not...thanks for ur opinions
