1.8 to 2.0 turbo engine swap

[js93eclipse]

first i would like to say thanks to everyone for the help.Basicaly i have a 93 eclipse that doesn't have enough power and i would like to swap engines.I would like to know if it is a possible and wha would i need? The big question is what engine should i choose?

The first question to ask yourself is if the swap itself is really worth the time/effort/money put into it.

Its going to cost so much you honestly would probably be better off just buying a TSI/GSX/GST.

If you are going to do a swap though just do the 4g63T 6 bolt since its the easiest you will find and there is lots of information about them here.

 

[js93eclipse]

Well, i've already put a good bit of time in to it and a good bit of money to .I don't think now would be the time to quit.I love my car and im not a quiter so i will see it through besides i paid 100 dollars for the car running,and this is my first time trying to build anything like this and im already having lots of fun.Anyway what about censors and axles,will they work?

 

[93ETGOCART]

the swap is price efficient if you can find a running wrecked turbo vehicle for a good price. they are out there you just have to search. I myself dont think if you have a running 1.8 you shouldnt mess with it. save up and buy a tsi/gsx/gst like gusu said. but if you must do the swap send me your distributor so i can get my 1.8 up and runnin . Good luck with whatever you do

ya i just did this swap... did a complete rebuild on the motor first then dropped it in the DL model... everything hooks up pretty much perfect EXCEPT the front motor mount. The holes don't like up, so you either have to drill new holes and bolt it up with some nuts and bolts (which will work) or do what im going to, you can measure out where it needs to be and get a shop (or if you can) weld it on the cross member bar!

other then that... it was pretty easy i ran into my own problems with it tho!

1)Oh and another.. you will need to switch out the 1.8 wire harness with a 2.0 harness along with the ECU and MPI relay!
2)You will need to either buy a walbro 190 fuel pump(you can get a 255 but you would then need an AFPR) or just get one off a turbo model!
3)AND last thing i believe... you will need of course, a boost gauge, which even on the tsi and others you should upgrade anyways!
4) I would if i were you, replace the CV axles anyways, altho they WILL fit they are meant for 1.8 models!

Having done the same swap your contenplating myself, I can give you tips here and there.

1) It's not worth the effort to convert your current (1.8L) wiring harness to a turbo harness, just get a good turbo wiring harness from a 91 - 94 turbo car (fwd, awd, auto, 5 speed doesn't matter). Also, you'll need an ecu, MPI relay, and turbo MAF if your sticking with the stock parts.

2) The 1.8L axles will fit into the fwd turbo trans, although I have no evidence showing they are weaker then turbo shafts, I can say that they have held up well so far on my swap

3) The wiring is simple, just take out the old, reinstall the new. No plugs need changed or modified.

4) The drivers side (timing belt) motor mount is different from the 1.8L to the 4g63. Also you'll want to use the turbo fwd center cross member for the front lower (under the turbo, near the radiator) motor mount.

5) The fuel pump sending unit in the non turbo cars is a little different then the turbo's. A turbo pump will fit. I just used a worm gear (aka hose) clamp to secure the pump the hanger. Also the power wire is different.

6) The hardest part of this swap for me was finding a good running 6 bolt. Other then that it's a very very easy swap. I'd recommend changing the timing belt and doing a BSE if funds permit while the turbo engine is out of the car. If you have any questions feel free to ask here or PM me. I have pictures of a lot of stuff, and get answer any question about the swap you might have.

 

[skatershawn]

ok yes i forgot to mention the motor mount on the timing belt side.. you must replace that with the one off a turbo model.. and if you can, i would change out the stock motor mounts with something alittle more stable!

And about the cross member... WHY DIDN"T I THINK OF THAT?? hahah!
man i wish i would've read that statement alittle earlier!!

Plugs are the same.. but the wires are not!
and IF you are getting a getting the 6bolt motor out of the 90, its best if you get a wire harness and ECU from a 90, so you dont have to convert most of you sensors to work with the 91-94 harness.
If you get a 90 6bolt and use a 91-94 ECU and wire harness, you'll have to switch out the Throttle body and all its sensors (TPS, ISC, PowerTransitor, Coil Pack, CAS, etc.) to work with the 91-94 harness!

Best bet is to get all from 90 6 bolt model! and that would be the easiest in my eyes!

That's so cool thanks.All this info will come in handy thanks again.So how would a jdm 4g63t with trans and ecu sound.One of my friends turned me on to them,i found one with all the above for $2000.please be truthfull because i want to do the best that i can.The parts guy that i talked to said almost the same thing that you guys said.The only thing he said diffrent was that all the motor mounts would workwith the jdm.

 

[Dsmj89]

Just sell your car and get a turbo model 1g. I've seen them for sale for very cheap nowadays. It's much cheaper in the end and will save you the hassle.
Just my 2 cents.

 

[js93eclipse]

Oh,fellas/ladies can anyone reccomend a good exhaust?

 

[dsm-onster]

Unhook you down pipe from your o2 housing (only to retaine you ro2 sensor, other wise do away with that too). . .

A turbo motor likes no exhaust . . .

Ok i know you a DSM Wiseman and all but that isn't very street legal... well atleast in texas it isn't!

Plus it would not only sound insanely loud and at some point become obnoxious.. not only that it would help burn a hole in the ozone faster!

Ive heard alot of people on here liking the ebay cat backs... i personally would just get a good muffler of you choose (A GOOD ONE) and take it to a muffler shop and have them weld it up with new bigger piping!

 

[js93eclipse]

What size and why

It was a silly question, IMHO. The answer still stands as the best for the most power. The OP did not ask how Al Gore would feel. I'm not promoting this as a street solution. But is IS DEFINATELY the best solution for the most efficient exhaust. . .

. . . My catless dsm passed the sniffer . My camry with stock exhaust didnt . . .

haha ook ok you make a good point.... haha!!
ya... Al Gore,... haha

ya that question was kindof open for a wide range of answers and opinions!

but to answer the size...whatever you want!!! I have a full 3" turbo back with test pipe... like it alot but its all on your preference!!

and why you ask.... i dont know... WHY?
i don't really get why your asking me why!
sorry! :/

 

[js93eclipse]

because i know squat about cars im learning as i go and because you guys know more than me,,need i go on?

You will need the turbo transmission also. An ACT 2100 or equivalance is a must. They can hold almost 300 ft/lb. The torque steer will be something brand new to you. Just learn to anticipate it. An LSD insert will eliminate SOME of the torque steer but will still be there.

What are you doing for intercooler? You will need to mod the bumper area for an intercooler install. Get rid of stock air baffles, fit an intercooler, build new ones out of sheetmetal for better cooling. Change your heater hoses out also. Your 1.8L power steering pump will work fine if you dont abuse it. Change your brake calipers to something of worthy braking power. Try not to cheap out as best as possible.

I dont regret most of what I did with my car before I crashed it after school one day but if I could do it all over again I would have kept my 1.8L as my DD and modded an AWD from the start. Even with small turbos FWD shows its limitations.

 

[skatershawn]

You can use the stock side mount on you car... it has all holes from piping and all holes for the bolts to screw in! The Side mount has been proven to withstand some high numbers soo if you are just planing to have a DD side mount will do fine but front mount looks sweet!

heater hoses and all that... thats just little talk you would have to replace, nothing to worry about!
one thing i had to get rid of tho, was my cruise control! But shi* i never used it!

Yes you will need the FWD tranny off a Turbo model but i was assuming you would get that with the engine like i did!
And if you do there is no need to replace the clutch with an ACT in less you WANT to... and if you need a clutch and have to money.. ya i would go that way but if not the OEM Clutch works fine up to around 280-300 hp might have alittle slippage but its about about how deep you pockets go!!

And Brakes... Its ALWAYS good to get better brakes but once again, its all how much you have to spend! Your stock 1.8 brakes will work fine at stopping you like they did before you drop the 4G63T into it, they might work alittle harder to stop the extra 100 pounds... but i dought its anything to really worry about! Inless ofcouse you doing AutoX but then you would replace all that anyways!
All i will say about the brakes is don't be dumb and haul ass in traffic and suddenly need to brake.. cause with any brake system that isn't smart!

But its your build, you do what makes you feel accumplished, as it should!
Good luck and just research before you ask most things as it will make people on here unhappy!

 

[js93eclipse]

Alright man,I try to do more searching before i disturb the sleep of the dsm gods.you still didn't tell me what you think about the jdm and it does come with the trans and ecu.

 

[slinarez25]

A far as i know there weren't any DSM's made in Japan, so what jdm engine are you talking about? The only jdm engine i can think of working is the evo 3's. But that tranny is only awd so im not really sure on what engine you found .

 

[kottyking]

galant vr4s were in japan. Mad tyte jdm.

 

[slinarez25]

Were they? Thats good to know.
But he is talking about engine and tranny combo, and his car is FWD so im assuming the tranny is FWD as well and i dont believe vr4's were FWD. Im not sure about the jdm ones but i still dont think they were.

 

[skatershawn]

well i believe some who try to sell the 4g63t cyclone motor label it as a JDM motor!!
please dont quote me on that but if i do remember there is some websites that say they are and some ebay stores aswell!!

now as for doing the swap.. we pretty much lined up all the info you need to do it.. but i will say, if you want to put the time into the swap that is needed do it! its your project dont let people hate and say it isn't worth it!
Cause to you,.. IT IS! To me it was WELL worth it! Its Custom, its something not alot of people have! You make it look nice and have documents on the whole swap, you can get better ratings at car show for doing such a custom build!

Not only that... you insurance will be lower, and to me... thats a plus!
My driving record isn't so good from years ago!

But the main reason i did it is, i got the motor and tranny free off my bro, had my DL MINT condition, with everything i wanted in her... spend the money to rebuild the motor and dropped it in!
And the Feeling to have this custom build weather you do it you self or pay someone is still worth it!

I say if you have the time and money... DO IT!
At times it might get stressful and youll wonder why you didn't just buy a gst or whatever... well overcome that it will get better! hahah!

ok this is long im stopping!

 

[projecteclipse2]
