big bore kit for 420a

[CVD]

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" ?
I dont think we need a dyno and a calculator to figure this one out.

Zero parts designed to make horsepower. And we're done, please try another platform.

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 (http://www.hahnracecraft.com/auto/eclipse/eclipse.htm), SBR (http://www.slowboyracing.com/more.php?id=5331&), Modern Performance (http://modernperformance.com/dcx/oneclipse.shtml) 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.

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!

So, if you really want one, it will honestly be much cheaper to sell your car to someone who isn't looking to make more power, and buy a gst. You're parts vendor will still get upi discounts, but the parts he sells you will make more power per dollar. Think of it that way.

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.

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 :)

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

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.

there are endless possibility if you apply yourself with the right resources and positive attitude!

goodluck with what you end up doing.

You are right I have gone down that road and I am just trying to save this person some money. The key thing you are missing is that if he has endless money than he would have endless possibilities. I don't know of one 420a with less than 3k invested into the car that will break 13 second quater miles.

Not to be an ass but define slightly modded 4g63t. There is no way a 420a with 6 PSI can keep up with a slighty modded 4g63t. Either the guys with the 4g63t have a problem with their car or you have more than 6 PSI or you are racing one of acidrumz 4g63t powered cars.

I wish this guy the best of luck with his build and I hope he does not get dissapointed 5k later and find that he can barely break the 13's.
Good luck.
