Hi I want to make my 4g15 into a 2.0L or as big as I can. I plan to do this over winter so if anyone has done this then please let me know if i can do it and how much everyone else bored it. I would like to use high comp pistons and ram air it. I will use a apexi fuel mangement system so i can run 660 injectors and a fuel rail off of a civic with slight mod to it. Upgrade the fuel pump and thats about it I think. I don't feel like spending $3000 on a front clip off a dsm. I would like to turbo it but I suppose ram air will. And I think fixing a 4g15 will be much funner to fix and original. I will be thankful for every bit of advice.
thanks Aiden

if you're looking for just displacement, why not look into the stroke as well? and I'm no expert but I don't think you'll be able to get 2.0L out of that 1.5.

Ok, all of this will cost you much more than $3000. No ram air is that efficient either....I say it is original, but much more trouble and very costly.

Considering the 4g61 with 2.0 piston only nets you 1.7L sorry to say your not going to get even close... to get close you'll need...

a) Custom Crank
b) Custom Rods
c) Custom Pistons

then you might be able to get close but I still doubt you will hit 2.0L and its going to cost more than its worth if you can'tt afford the turbo setup why not just buy a 2.0L N/A it will add ponies the minimal cost.

i didn't feel like doing that swap as I don't want to febricate new drive shafts and everything else. It seems like alot of bi*ch work on a 4g15-4g63t swap. Then you have to find a front clip that is worth it. With high comp pistons you wouldn't need to change the stroke. I want to get max displacement with max compression. The ram air system is quite easy to do, I would put a turbo but don't know where to get any of the parts to do this. I would just like to know how much everyone has been able to bore. What is the max?

Dude.. haven't you read any of the archives? the 4G15 -> 4G63T/61T swap is plug and play if you have the right parts.

The only "trouble" you'll really run into is if you don't have the right parts and start to mickey mouse. IE. wrong wireharness (you'll have to cut some wires), wrong linkages (might have to move the shifter up an inch I've heard), etc.

The amount of labour going into making your SOHC 12v into a 2.0 is significantly greater, and more expensive than to purchase a 4G63 which already is 2.0 and has some other benefits, ex. DOHC, 16v.

and then with the '63 you can bore it way beyond the limits of the '15. But if displacement is what you're looking for, get a 4G64.

From what I've seen here (and I 've spent alot of time here over the last 1.5 years) no one has over bored this motor by just boring the motor you don't pick up much extra displacement because the stroke is so small you have to bore and stroke a motor for any real increases. I would say you could hit about 1.6L on that motor safely... and you don't have to custom build anything for this swap you can use your factory CV joints many people here do that motor mounts are also off the shelf you want easy and your trying to jam 2.0 pistons in a 1.5 that sounds like too much friggin work to me... Turbo is a pain in the @$$ to source all the little bits you need thats why I'm building a 2.4L DOHC N/A beast nothing custom in that unless I decide to do custom 10.5:1 pistons...

I second that, turbo is a biatch =D
and Berserko, check your PM ;/

Dude, can you read? There is NO FABRICATING necessary. Off the shelf mounts, off the shelf driveshafts (hell, use the ones in your car already), readily available trannies (again, your car has one), its frikkin easy...the easiest bang for the buck swap out there.

Yeah I know I said what others have said, but this is just silly

can you even get it bored to a 2.0? what about the cylinider walls being to thin?
just do what berserko's doing, DOHC 4g64... his motor will proabaly end up being a beast, but mine will be more powerful heheh
If you need mounts i can get about 5 sets if i wanted to.
Tim, you need to do a 4g64 write up.
Aiden: unless your doing an AWD you dont have to worry about half shafts.
Only thing i can think about is that the COLT GT has equal length half shafts, where as the colt 200's have unequal

I don't want 400hp though all i want is to make this car more fun to drive... and I would prefer to have more power down low than up at the top especially for all the city driving I do....

1.7L is about as far as you can go with the 4G15 bored and stroked - they are only 1468cc to start with. But you still have the sucky under square bore-stroke arrangement which means it will never rev very well. Ultimately the 4G15 is an economaster/low emission engine not a performance engine.

Where can you get 4g64 engines from? So if I get a 4g63t engine I can just bolt it in, if I have the front clip off a dsm? I dont want awd just fwd.

all you need is a DSM front clip and motor mounts from a 92-95 Hyundai Elantra 1.6L and 4g64 motors cams in 89-91 Hyundai Sonata 2.4L

4g64's also came in vistas...did they not?
