Performance Tips

[S|iK_GsX!]

Hey, does anyone have any tips about increasing speed and performance of a n/t eclipse besides a turbo kit. I have done intake, cams, exhaust and headers.

Face it, if you wanted to go fast, you started with the wrong car. NT Eclipses are dogs. You're going to have to go forced induction via turbo, supercharger, or nitrous oxide if you want to be even remotely fast.

 

[special_K86]

not really, with the right stuff you can be running high 13's going n/a. It's more costly then just going turbo, but still achievable- Kevin

I disagree our n/t can knock of low 11s whithout head work and we don't have to worry about crankwalk I used to want a 4g63 but now I will eat up a gst or a gsx the 420a is a great motor all it needs is a little force induction.

SLik GsX, if you dont want to go turbo get an under drive pully AFX has a nice one for 140, wires, hotter plugs, MSD coil. Every little thing counts.

 

[RedLineShifter]

what kinda gains will an under drive pully give a n/t?

 

[DSM-ZERO]

The AFX is a 30% under drive and will give about 10-15 to the wheels it is also 3 pounds compaired to stock which is 15.

13's i'll believe, but i've yet to see any 420a powered DSM run an 11. sure they've done it in a neon that is totally designed only for the track, but that thing probably weighs 700 pounds less than some dsm parts cars due with half their mechanicals out.

I have seen a 420a neon go 9s....mitsu turbo and nitrous though, granted the eclipse is a bit heavier, but I could see 10s as a possibility with enough work, anyway you can build a NT engine for an eclipse just like you can for anything else, like they said, it just takes more money, high compression pistons(12.1:1 or something like that)underdrive pulley, rip out the a/c system, rip out the power steering pump, it all depends on what luxuries you can do without, I dont know if the 420a has balance shafts, but if it does, remove them, you can port the intake manifold and the header, you can get head work done, porting the head, 3 angle valve job, etc, etc, get solid motor mounts to put the power more firmly to the ground(or fill them in yourself)MSD ignition, coil, plugs, etc, still wont be as fast as a stock turbo, but it should come out somewhere in the upper hundreds, you can also fabricate your own ram air system, might take 2/10ths off if your lucky, but with a 4 cylinder more likely just 1/10th, then all the lightening of the thing you can, because that thing is one heavy car

HRC got an Eclipse RS to run 11.53 @ 123mph

and that, folks, goes to show you how little i know about 2g nt's

Thanx, but what type of MSD coil, plugs and wires are good for a n/t. I have Bosche +4 platinum plugs and NGK platinum wires, i dunno if these are any good or not.

 

[DSM-ZERO]

Dont waste money on those plugs get ngk's they are the best for our car.I cant remenber what # they are but I think it's EBK11es but I am not sure you shold get pluge that are one range hotter than stock MSD only makes 1 coil for our car so thats easy and as far as wires you should go whit a 8.5 or 9.0mm.

dsmrunnah95, we were talking about a 420a going naturally aspirated. He wasn't talking about going turbo. So the HRC rs going 11.72 doesn't relate to this because they put a turbo on it and then again it was a fricken Stage 5 turbo kit. And when they ran the 11.7's, they were running 28 psi. Thats a whole fricken load of boost. They were estimating the hp to be 475. So i think Mavisky would be the right one with the 1/4 times. And by the way he's a fricken moderator, i don't think they would put a dumbass for a fricken moderator. I think we all can learn something from Mavisky, so props to you man. - Kevin

 

[mavisky]

actually when it comes to the good ole 420a i still have quite a bit to learn. but luckily i've got a good bunch of experienced 420a wisemen to rely on.

Ok, show me anywhere in the part that I quoted where Mavisky said anything about being n/a running 11s and I will retract my statement. I believe he said "but i've yet to see any 420a powered DSM run an 11" now I wouldn't have posted my reply if he had written "but i've yet to see any N/A 420a powered DSM run an 11".

 

[mavisky]

in that case it was my forgotten word as i meant an na dsm. i understand the confusion though, although for future reference i would refer to turbo 420's as a turbo'ed nt or something, plus this is the nt forum.

 

[senseiturtle]

Fastest I've reliably heard of for an all-motor 2g is around 15.2 in the 1/4. Fastest for a turbo'd 420a, something like 11.7... and "usual" turbo 420a is about middle 13's.


keep in mind i'm excluding these corporate sponsored cars in the turbo-420a department, i'm only familiar with the more realistic times. That 11.7 time is claimed by a member on the 2gnt.com site, and i'm not sure of his name.



*This isn't bad considering that its NA, and stock is something like 16.4-16.6...

There is some guy claiming ~14.6 all motor on 2gnt, but I have yet to see a timeslip or hear a confirmation. I dont really spend enough time on this particular site to know what's being claimed here.

 

[wicked93GS]

I think 14s anyway are possible for a NT 420a, if a DOHC neon can go 14s with under $1000, it cant be that much harder to get the eclipse to do so too....you'd probably have to stripit a lot though

 

[Bohica]

I am in the same boat. Or in a similar boat anyway. I am trying to get a 1st gen N/A to go quick. And all paths point to one conclusion.

If you want this thing to be fast, you are going to have to put that pig on a diet. That is what I am going to do.

 

[senseiturtle]

I guess it simply comes down to...

"what do you want?"

I want a decent-looking daily driver, with the little extra punch. Not too bad on insurance, ATX (convienence), semi-good on gas, and something people would look at and go - "nice car."

I can't afford a 13 second car right now... and i dont have the resources to keep one up. I wanted a gst, dont get me wrong, but i'm good with the RS.

If you want to tear up the track... yeah.. n/t eclipse isn't for you.

Thats what most owners dont get!!!!
the 420A Is a great engine better than any Honda better than the 4g63
i dont want to start a war here but its design is brand new and can run 25 psi on a stock top end that was designed by Lotus, not many cars can do that . the 4g63 is over 10 yrs old. time for an upgrade. crankwalk. mitsubishi turbos are junk compared to the new turbos out there and chances are if you have a 4g63 you have a mitsu turbo. for the 420A the options are now limitless. the Turbo boys now are going to be jealous lata. :laugh:

10-15 to the wheels? for like $140? dayum...thats some great gains. i may hafta buy myself a present..

 

[DSM-ZERO]

It is really a great buy and I am pleased whith it and it is not hard to install go to www.howellautomotive.com for more info on the UDP

It is a great buy and I enjoy it go to www.howellautomotive.com for more info

I wouldnt say that the 420a is better than the 4g63, I will admit it has the same potential though, come to think of it, maybe a bit more(there was that neon that runs 9s after all with a stock head(with a mitsubish turbo btw)) but a properly done 6-bolt 4g63 is almost as good as a properly built 420a, its liek comparing apples and oranges, anyway UDPs tend to give a decent HP gain, though 15 seems a bit much, probably about 10 to the wheels, which is a great deal for 140 or whatever the price is, he he, the 4g63s have an advantage though, we can gain 15 HP just by removing the balance shafts, cost:$0 thats what I'm going to do, combined with an UDP and turbo cams, intake and exhaust, he he
