4g63 Stealth...

This is just a fancy idea at the moment... but would it be too hard to throw a 4g63, say Evo engine in a Base Stealth.. I was wondering how much that would take... b/c I know someone who's selling an engine very cheap... and the idea hit me... plz don't laugh, as I said this is just an idea... I haven't put too much thought into it yet...

no.

ok... thanks... that's all I needed to know...

How about this
6 > 4
3.0 > 2.0

So why do all the custom work to make a smaller engine fit in the car. No one, I repeat, no one custom installs a smaller engine in a car. Anytime an engine is swapped for another one there 1 of 2 reasons for it, its bigger, or it makes more power. A 4g63 fails on both acounts.

well, I'd be going from SOHC, to 4g63... to my knowledge, the Evo's putting out 276 hp... way more than I'd be doing stock... more than I got for now... but I have also had those thoughts pop in my head since I posted the first comment...

Theoretically, you can do it. Would it be wise? Nah. Expensive? Very. Time consuming? Yes.

The Evo also has a decent sized turbo, I believe a 16g, that's how it gets to that hp level. Larger than most stock turbos to my knowledge.

Not always. I can almost assure you that the 4g63 can handle more hp than whatever engine is in his stealth, without upgrading internals. There have been people with 500+ hp on stock 4g63 engines, without problems. I don't know if you can say that for the SOHC 3.0, correct me if I'm wrong.

yeah, I got a friend with an MR edition EVO, he put in a MBC, and a fmu... and upped boost.. running a/b 320 hp, changed out nothing else... though he's got a lot more money than I...

I was wondering... what other engines would be easily transplanted into the Stealth (by easily, I simply mean, can yield high #'s, and will line up with motor mounts...)...
I've heard that you could simply throw in the 6g74 and boost it...

um, the 4g63 and the 6g74 are not dirrect swaps.

You say you can get a cheep 4g63, is that the 4g63 from an evo? I highly doubt it.

You want an easy 320hp, buy the vr4 that is for sale on here for 2 grand and swap the motor. That is the cheepest way you will get 320 hp into your car. Then you can up the boost, and prolly get close to 360-380.

So back to my original post

NO!

true... I just knew someone who was selling theirs... and yes in fact... the EVO 4g63... car got totaled.. insurance write-off... he bought the car back for like $100... so he's parting out what he can... he's already made more than he had invested in the car, btwn the insurance check and what he was able to sell

The only motor that swaps in is the 6g72

sry, I heard that the 6g74 from the Montero's would fit also...

it will fit, but so will a mopar 440. But it doesnt fit your critera of a simple swap.

ah, ok... I was beginning to wonder... b/c I had heard that someone did it... and boosted... I b/l they got a site a/b it somewhere...

I got an idea lets make a wind up 3000gt, we can get the wind up crank, spring and input shaft from one of those little clown car toys and swap it in. Come on its an idea, or you could just follow the 3si na upgrade bible... http://www.3si.org/forum/showthread.php?t=85924
hey slowly upgrading is better than never.

about the montero engine. has any1 put down 1/4 miles times for having that engine in an n/a?

Just an FYI. Its not actually the montero engine, its an engine out of a JDM car that isnt sold in the US. It is the same block, but in order to get most of the parts to line up correctly you need to get the FWD version of 6g74 along with a lot of JDM only parts.

Yea I talked to the guy that did it when he sold it on Ebay, I believe he had time slip/video proof of 13.5 @ ??...I know he told me 13.5 and i'm pretty sure he had the proof, it was a while ago though.

dang. an thats leaving it n/a? i was thinkin of doin a montero engine an put a twin turbo on it :) .. i know, a lot easier said than done.

true... I knew it was a jdm engine... and most of the parts will have to be JDM... but I was also under the impression that it was the montero engine... 13.5, not bad for N/A.... better than what I'm putting down now...

Haha a 4G63 Handle more HP? haha a 4G63 is a Eclipse GST Engine! how many Eclipse do you see broken down? ALOT! My brother Blew up his Eclipse motor just by puitng a 16g turbo on it with stock internals! then even better he had mabey 300 to the ground and went to the track and launched his car and DESTROYED THE DIFFERENTIAL! (plus he has been through 2 trannys) there is no way a 4G63 can hold more than 500 hp either in the EVO or Eclipse with stock internals. A 3000GT is known to be one of the toughest cars Mitsu made and can hold up. so if a Bolt on 4G63 can have 500+ HP Then a Bolt on VR4 can have 650+ (NOT). Not to come off as rude but thats just my opinion.

And for the record it is possible BUT pointless to put a 4G63 in a 3000gt.
but if you do it requires some fabrication.
Infact my freind did the opposite of what you did. he took a first gen Eclipse and Fabricated a 6G73 into it, and its a bad little car, its quick. but he had to do custom suspension, mounts, drive line, ect... so if something breaks he is in trouble.

True... that's what worries me about going completely custom... I thought a/b getting my own welder and doing the stuff... I took welding classes... and no how to use the equipment... but I don't wanna be going down the road and something snap... that'd suck...

I'm not going to get into the whole my brother did this and that thing. That was one experience. Dozens of people could come up with some story about blowing trannies and destroying diff. in a 3kgt also. Infact, I read alot about how the 3kgt tranny is one of the weakest parts of the car.

You "see" a lot of eclipse's broken down is because people think they are in a F&F movie, and beat the piss out of them. They are also very easy to mod, and many parts are made for them. Mods + dumb people = problems.

It is a KNOWN FACT that many people have achieved 450-500+ hp levels on a 4g63 with stock internals, and when tuned correctly (which is what your brother sounds like he ignored), they are surprising sturdy. Yes, as with any highly modified car, there will be problems, but it has been done by more than a handful of people. BTW I believe there was a recall on the differential some time back, that could have been a cause to your brother's misfortune.

Also, your sig. is huge. Might want to shrink that a little.

Tcase is week on the 91-93, not the tranny
6g72's have been known to have 500+ awhp on the stock longblock

Not 93.5 they came witht he 25 spline transfercase with a 5 speed :smile:
I know cause I have one and they are rare.

My brother did tune it... Infact he tuned it his self. You might think thats was his prob but no... after his incedent he went and got a first gen 6 bolt block and put it in his 2g and built the car it all to hell (over $30,000) and puting out 600 to the wheels BUILT. and he road tuned it him self and it has been holding up for little over half a year.

Now I was right the first time. The 91-93 tcase is weak. They switched to 25 spline in 92.5, but the case itself is still pretty weak. Its made of cast aluminum, and is known to crack in 1/2. The 6 speed tcase is made of cast iron, so it is much stronger, but when you put too much power through that you start to shred the gears inside the case.

I have lots of power going to it and its held up great :) :P
