Re: big bore kit for 420a
95 gs eclips! i could, but i dont really like the idea of having my baby on the bottle! i am going to build up and run an ass load of boost
"the only replacement for displacement, is a big ass turbo:D " sorry bad spelling, it's to early for me:rolleyes: |
Re: big bore kit for 420a
You should consider doing a 4G63 swap. You can get longblocks for real cheap, and they are pre-built for boost! I would even venture to say the 1G 6-bolts are pre-built for 'ass loads' of boost, with their low-ass compression: 7.8:1 !
'Big Bore' kits usually work well for bigger motors, since going .040 over on 8 cylinders of a 5.7L will yield a lot more displacement than going .40 over on a 4-cyl 2.0L. Might wanna do the math and see how much it'd be worth :) |
Re: big bore kit for 420a
Building the motor for boost will probably make you lose power overall when you are still N/A. Your best bet is to have a turbo kit installed that is designed for the stock motor, build the motor and turbo system at once, or possibly purchase a more boost friendly car. (or motor swap)

Re: big bore kit for 420a
I used to be into the 420a platform. I must say it was much easier to work on than a 4g63. The engine does have potential, but it doesn't come out of the box with it. Many people say that you should just do a 4g swap. I say you should head over to 2gnt.com and search over there, since you'll get a better responce over there. This is more of the GST/X crowd, however all Mitsu's are welcome.

Re: big bore kit for 420a
The nice thing about the 4g63's is the vast amount of parts available for them as they are turboed stock.
Anyways, I would steer you away from buying a kit and piece together exactly what you want to reach your goals, at least in regards to the motor. Is it turboed already, or is that a future plan as well? |
Re: big bore kit for 420a
ok i am dumbfounded here! i was going to do a first to second gen swap but it take way to much custom fabing all the mounts are in totaly different places, and tranny is on opposit side's
what i am woundering is the 2g 4g63 have the same mounting possisions as a 1g 4g63. but ya i did a lot of reserch on that type of swap and it's impossibe for me to do! sorry for bad spelling |

i guess you already have a n/a 2g to arrive to that solution that they are "slow and take too much money to build" ? there are endless possibility if you apply yourself with the right resources and positive attitude! goodluck with what you end up doing. |

Zero parts designed to make horsepower. And we're done, please try another platform. |
Re: big bore kit for 420a
While I do agree with everyone here that the 4g63/4 engines are the way to go, there are people who specialize in the 420A engine. If you are dead set on using the 420A, we could be a little more helpfull ;). Try HahnRacecraft, SBR , Modern Performance or any of the vendors listed on this site.
If you are wanting to put "ass loads" of boost down something, sell what you have and buy a GS-T or GSX. |
Re: big bore kit for 420a
o i have a parts vendor that i get mad discounts through and free shiping on every thing! i am just trying to figure out where to start. and yes i was kinda wanting to use the 420a not many people build them up! so i think i am going to take on this task! but oh man would i love to have a gs-t!

Re: big bore kit for 420a
I would say stick with the 420a. It's a nice platform to work with. There are more people than you think building them up. I have put a turbo on mine about a month ago and am pushing about 6 psi. It's pretty quick now, can keep up with slightly modded gst's.
You are right, a 4G63 swap is not good for our cars. You might as well swap in a Toyota or Honda or any other type of engine because it would take about the same amount of work. The 420a is a Dodge/Chrysler engine while the 4G63 is a Mitsubishi engine. Everything is basically different between the two. I pieced together my turbo kit for about $1400. It's still on stock internals so anything more than 8-10 psi is not recommended. If you would like more info about what to do, give me a pm or check out 2GNT.com or DSMTuners.com under the 420a section and search away. Plenty of info for what you are wanting to do. |
Re: big bore kit for 420a
I had a 420a and it was a hunk of crap. I did a lot of looking at the possibilities when I had it and when it came right down to it, the $1400 is more than twice what I paid for my TSi. And in the end, the 4g63 was a lot easier for me to work and and figure shit out on. Then again, 95% of my friends knew them inside and out, and so it was MUCH easier for me to learn like that. I look back on it all now, and I see that my 420a Talon was an excellent way for me to get hooked into these devil cars. It was SEXY.. I mean come on... But it wasn't fast and it would have taken a lot for me to make it fast. It would have costed about the same as just buying a decent 1g AWD! Plus 8-10 psi isn't that great. I was hitting up to 16-17 psi in the stock TSi after her turbo was replaced :)

Re: big bore kit for 420a
THANK YOU! atleast some one is on my side for the 420! and with a little work i could have a pretty nice setup!
but thanks for all of the input everyone!:D |
Re: big bore kit for 420a
How is it easier to work on a 4g63 compared to a 420a? My RS was much more friendly when wrenching on it. My advice to you would be to build the bottom end. There is no way that you'll be able to keep up with a GST with a 16g. Plus you can run something a bit bigger. Only rods and pistons with some clevite bearings and you're in bidness.
