ok so i know the 4g63 is turbocharged engine but lets say the turbo was taken out. will the 4g63 be a more powerfull engine or will it be the exact same as the 420a.

i heard some people say the 4g63 was made with stronger pistons or something like that.

there is a 4g63(t) engine in the GST/GSX, it is a regular 4g63 with a turbo slapped on

then there is a 4g63 engine in the GS from 1990-1994

finally the 420a is the engine from the RS/GS in 1995-1999

the 4g63 is a stronger engine that can handle more modifications. It's transmission is geared better for racing than the 420a, and i believe that the 4g63 also has 5 more hp. Not to mention the fact that the 1g is lighter, and therefore... lighter plus stronger engine= faster

I think the 420a would win, especially if all you did was take the turbo off a 4g63t.

both are 2.0l DOHC engines, BUT

420a has 9.6:1 comp ratio, where the 4g63 only has 9.0:1, and the 4g63t is 7.8:1

420a has bigger bore, but smaller stroke.

4g63t just has a little bit stronger internals.

and 420a is geared shorter.

aint the 4g63 turbocharged already? i think that 4g63t is for g3 or something
im talking bout g2 eclipse here

so knowing that in a g2 the 4g63 is a better engine , is it worth it to spend 2+ more grand on a gst? i think it is , im just asking.

ok azncloud, your kinda misinformed

your original question was "which is faster? 420a or 4g63 with the turbo taken off?"

the answer is the 420a because the low compression pistons of the 4g63t (which is the engine in all g2 turbo eclipses) will not outperform the pistons on the 420a without its turbo.

but youve since changed your question to "which is better? rs/gs or gst?"

the answer is gst. but if you want a turbo eclipse, try to find a gsx. its worth the extra money.

there are no gsx for sale here and my buget is very limited.... so the gsx is out of my view for now....

also i have another question why is it that i see my gst spyders than gst for sale? are they both the same engines? cuz on autotrader i see more gst spyders than gst's.

cuz the spyder is a convertable, and they ALL leak, and there are quite a few problems with the frame for the tops too.. (just guessing)... :beer:

oh, and they weigh ALOT more too :57:

im not too positive on what engine the spyders have, but i THINK they have 4g64s in them (turbos and nonturbo). but once again, im not sure so dont quote me lol.

gst spyders are 4g63t cars just like regular gst's. But, they are too heavy to perform stock and some get upset because they have a turbo car that they think will match the stock gsx or gst but be convertible.

gst's are valuable because they are tuneable and lighter than the gst spyder and gsx but get lesser traction than the gsx. gsx's are more valuable because they are easily as tuneable but get twice the traction of a gst becuase of the AWD,,,, but are heavier. gst spyders are valuable for looks and open air appeal.

everything is a trade-off. AznCloud: what do you want from a car and we can help you find the one you want.

btw CodyRocks... nice job with the specs. 420a car would beat a 4g63t car with the turbo removed because of the lower comp and higher fuel volume to a n/a motor. it would run richer than donald trump (hope he doesn't sue for using his name) and bogg the whole way almost blowing raw fuel out the exhaust not knowing what to do with it's fuel/air map. :beer:

well thxs for all the help im still looking for a g2 gst coupe.

my dad is pissed though cuz hes like "eclipse break to much!" he wants me to get a toyota just cuz the engine is more reliable but i dont feel like wasting my money on a cow. lol

why does everyone say that eclipse break so much? i seen eclipse with 130k miles and never had a rebuilt engine.... i think its cuz ppl misuse eclipses to much or something but i find eclipses to be good sporty cars.

my brothers's gsx has never broken down cuz he maintains it like crazy....

:amen:

the 420a would not beat a stock 4g63.

But i suppose it could beat a 4g63(t) with the turbo removed

we should test that theory. i think the 420a could take it :clap: [/420a_pride]

the reason they break so much is because people change things. if you have a completely stock, maintained car it will last you almost forever with normal wear problems. when you start modding and pounding on the car is when you run into troubles

what type of mods? i dont think small mods like guages intake, muffler do much to the engine.

no, those mods wouldn't do any damage. the damage that would be caused by those mods is the 60 "mental" horsepower that come with them. when people make their car louder they, for some reason, think it is automatically turned into a race car and they can drive it with their foot on the floor, free rev the engine, and just beat the crap out of it and it will hold together forever.

I have a heavily modded car with 25,000 miles and counting after the mods without incidence. the only thing that broke was the clutch cable and a lateral arm. something like that would fall under the "$hit happens" category though.

it all has to do with how you treat your car and how you maintain it. I check my fluids 3 times a week at the least, check tire pressure and treadwear almost every other day and I drive the car like a normal person would 90% of the time. I do flog it every now and then but it has been built for that and she likes to be spanked on occasion ;) .
