Brand new. Bought 1st Eclipse this morning.

After purchasing my first Eclipse today I was excited to buy a few bolt on mods because it is bone stock. It is a 98 gs-spyder. I was confused. Why is my motor bigger than every other 95-99 motor besides the other non turbo spyders. How much slower is the 2.4 than the 2.0. Why dont they  have any aftermarket parts that I can find? Does the 2.4 have DOHC? Please just give me what you know about the difference. I am in the Military and would rather spend all my money on my car than anything. Should i put a 2.0 in it? Would that make it faster and easier to modify? Thanks

YOu cant just drop the 2.0 youre thinking of in there, the frame is different. Theres 2 flavors of 2.0L anyway, theres the GS/RS (420a) and the GST/GSX (4g63t). YOu have a 4g64, found in the 2g spyders and in the 3g GS/RS (Coupe and Spyder).

So the frame on the spyder gs-t is different than the gs?

Yes.. well sort of..... actually... it MAY be possible with the 4g64 (dont quote me on it) but I doubt it would be all that cheap to have performed. Personaly, Id just switch the heads out on it and throw a turbo on there... making it (sorta) a stroked 4g63...

how much less power does my motor have than a non turbo 2.0? y did they put a less powerful motor in the spyder?

Non turbo 2.0L (420a) has LESS potential power than your 4g64... but from the factory theyre about equal. I believe the 4g64 was put in there to account for the extra weight of the spyder to make it just as powerful as its hardtop counterparts.

"Drop" in the 4g63t head and you've got yourself a 2.4L turbo Spyder like Dusty stated.  4g63t guys are doing more and more.
Dusty, the Spyder bodies are the same whether turbo or N/A.  The motor of a 2G Spyder is the only thing different between the two and the 4g64 is even on the same side as the 4g63
I stated "drop" in quotes because it's not really a bolt on affair, there's more to it.  I'll find the link of a 2.4L swap in a few and you'll see what I mean Navyfc117.

Please give me a site where I can find mods. To start with cold air. just anything. It seems really slow to me? maybe ive been driving v-8's to long. By the way I appreciate all the help you guys have gave e so far and the quickness to respond. Forums are the greatest thing thats happened to the net. Off the subject question. are 18s to big? should I go 17s or 18s?

Thanks, Silver.. I was pretty sure of that, as they both used the same block... havent worked on many 2G Spyders (especially not N/A varieties), but it seemed right.

Ok my quesstion is. To modify my engine do I just order parts for the 00 and up 2.4?

Here's a 4g64 site. http://4g64.150m.com/performance.html
I haven't had a chance to find a swap page yet though.  Standby for that one.

I'm a noob.  There's actually a link in that link that has a site still under construction, but...better than nothing.

Here's using a 1G head..

I know I've seen more though.  I'll keep looking since this will be my next motor mod in a few years (after leaving this tiny rock with low speed limits and traffic for days!!).

Here's another with some detail from Tuners...substitute D S M T U N E R where the asterisks are and you're golden.

Oh yeah, that first link on this post has more 4g64 links at the end.

Wooooww, silver you really are hardcore, youre given something and you totally research EVERYTHING about it...... kinda like me, haha but im not much of a share person haha, ill read all that since a spyder is DEFINITELY in my future plans

It's in my future, so I've been looking at all this 2.4L block swap stuff within the last 6 months.  It won't happen until I leave Oahu though.  It just doesn't make any sense, since there isn't a track here anymore AND speed limits are too slow with cops on a rampage on this little paradise island.

Did you know that Hyundai had a "4g64" block but in 6 bolt form?  Not that it matters since the 4g64 crank is pretty tough and the term "6 bolt" doesn't mean as much with that motor anyhow.  At least that's what I've researched   Yup, Hyundai uses the Mitsu motor too.  They just relable it to something like GCxxx.  I even have a GC...er, 4g63 valve cover from a Hyundai Elantra 1.8L   It's more bolstered than the Mitsu one.  Now I just have to get off my butt and put it on.

I've got links of links and for days, I have links.  lol and they're all saved...just in case   Man, I would hate to lose all that info because of a stupid virus.
Yeah, I do a ton of research before I give in to asking anything, lol.
