swaping engines

hey everone...i just bought this 95 eclipse and i was woundering if i could swap the engine with a newer model...what complications might i have if i swap it with a 96-2000 engine. Imlooking for a used engine, and i dont know if its worth the hassel in swaping it. If anyone knows it would help me a lot...thanks

First of all, what kind of eclipse do you have?

And Its actually preferable to swap for an OLDER engine. Namely the 89-92 6-bolt motor:bigthumb: Although the 92 engine is considered the best , it has the better stock cams.

lol, which is the whole reason y u didnt buy a newer model eclipse:iceslolan :iceslolan lol, but yea 92 engine's best, if u can find a good one...everone obviously knows a shit engine is...well-shitty haha, man i need to stop staying up so late its like 9 am and i havent even gone to bed WOW but im not tired:thefinger :thefinger lololoololol goin to bed lol

The 6 bolt engines have the big rods, so those are considered stronger as mentioned above. See the magnus page for all the info you need to do it. I have done a few using the magnus method. If you dont want the hassle of the conversion, try to find a 99 motor. The thrust bearing design changed and you hear less about htem crankwalking. But that is the only advantage. 95-99 engines are otherwise the same. I wouldnt swap it unless it does CW. You can keep your 2g head either way, or you can swap to the prefered 1g head/intake/TB.

My car has broken the timing belt 3 times in less than 30k miles. The first time was at 86k and the belt was original(no damage done). 2nd the tensioner locked up and bent the valves. I think the balance shaft broke and took out the timing belt. I'm looking to replace the engine and was wondering if anyone knew about a more dependable, perhaps newer engine that I could get. I have a 92 laser rs 2.0 non turbo 5spd

6-Bolt is the only way to go.

A built G64B is the only way to go.

Umm why :confused:

Ummmm why would you want an 8-valve SOHC motor?:bloated:

Best I can figure is that he is talking about the 63/64 hybrid. And not all 64's are SOHC and 8 valves.

Its an old sonata motor. Its like a 6 bolt stroker. Yea the head sucks too, thats why you put a 4G63 head on it.

The stroker engines have no rpm potential. Why do you think high rpm , high powered formula cars have VERY short strokes , and consequently low piston acceleration.This stress's the motor out much less. I've also seen some guys with "strokers" at the track , and they get their asses handed to them by 4G63's all the time. Stroker motors are a thing of the hotrod past , and thats where they need to stay. I have yet to see a stroker in the 12's , and certainly not in the top 10 racers. All those spots are held by 4G63's.

Heres a listing from the Hyundai engine directory

REMARK YEAR F.I. CARB DISEL O.H.V. S.O.H.C. D.O.H.C. C Y L ENGINE NUMBER ENGINE SIZE cc DIA. mm NPR & NOA PISTON RING # A M NOA PISTON#
89-91 F.I. S.O.H.C. 4 G64B 2350 86.50 SWM31037OE AM 11-538
92-98 F.I. D.O.H.C. 4 G4CP 2350 82.30 NA TBA*

I can provide the complete list , but I doubt its necessary. As you can obviously see , the G64B , at least the Hyundai version , is SOHC only..............
:biggrin:

He said all "64s." Like the DOHC version used in Galants as an example that comes to mind.

And Marco Passante and others rev their strokers to 8500. Sounds like plenty of rpm potential to me. But it wouldnt suprise me if the really fast guys arent doing the opposite of strokers, but still over 2 liters, if you know what I mean :wink: I know on Shepperds 9.3 he said that he no lift shifted at over 9500 rpm. Hmm... :wink:

I just saw this little tidbit of missinformation... Here, I did some research for you, took all of ~45 seconds

4G64: (A 2.4L 4G63? Yep.)
Stepping the ante up one more time in the quest for more hp, we developed the 2.4L DOHC 4G63/4G64 engine swap for 1st and 2nd generation DSM's. Providing more than 130 extra ft/lbs of torque and 50 more hp. Piloted our race car to an astonishing 10.06 @ 140 mph without the aid of Nitrous, and a new best of 9.623 second ET with a 152mph BEST. Still being able to rev until 8500 RPM.

And to further my speculation about what the fast guys run:

New hybrid motor:
Our new motor will have some unique features not found on our other engines. Increased cylinder filling and the ability to rev even higher. Could more displacement be in our future? That's all we can give away right now.

:wink:

The only listing I find of the G64B in DOHC form is in the 85-87 Galant. I've never seen one of those cars. I have seen that so called "stroker" engine in action , and I think I'll stick with a 4G63. If the racers are going with stroker motors, then they are going the wrong direction. Stroker motors are more highly stressed internally , due to piston acceleration and rod length. I could see increasing bore , but not stroke. It has too many disadvantages. I didn't think Shepard was using a stroker , if he does, thats news to me. Call me a purist but I beleive only the 4G63 block should be used. Thats like stuffing a small block with nitrous in an RX7 and then running 7's. Its not the same car anymore. I can respect the racers that stick with the original blocks and can still run 9's.

And I certainly have no respect for Buschur. Running a low 8 in a car with a solid rear axle , and basically no DSM parts left but the body , can only be classified by a true DSMer as sacreligious:mad:

Damn, you reply fast :wink: I didnt mean to imply shepperd was running a stroker, in fact I suspect the opposite. Strokers are going to 8500, I highly doubt they will ever see 9500. The stroker motors we use are not simply stroked 4G63s, but full 4G64 with DOHC head or 4G63 head conversion. The bore is larger, and the rod ratio/angle is WAY better than a stroked 4G63. SOme DSM vendors, like SBR, wont even sell a stroked 4g63, just 4g64s. And Bushurs car's body isnt DSM. The only thing that is DSM is the motor. Just like other cars in the DSM powered group. He runs 7s, which I wouldnt try on DSM drivetrain. Extreme did 8s on it, but had to by a new tcase after a few runs, and trannys didnt last long either. Rumor has it you cant buy a used tcase within 100 miles of extreme, lol :wink: I think Shepperds car is the purest in form, and runs 9s on street tires wihtout many breakages despite short times in the 1.3-1.4 range. 1.4 is a long way from my 1.5s too...

I have no problem with people running a 64 block. its only .2 more liters, which is a far cry from the bigblock small block example you use, but I certainly see your point. The biggest advantage really is just being able to spool a larger turbo without nitrous. The more toruqe aspect I see as a dissadvantage for powerful cars because of drivetrain weaknesses at that level. But none the less, many people are doing very well with the 4g64 block... Its too bad the 6 bolt ones are so hard to find, or it would be a cheaper option...

And I too perfer stock discplacemnt rx7s that run 7s. The v8 swap in an Rx7 disgusts me. :smile:

I thought Buschurs car body was a 2G DSM body???:confused: Or a fiberglass look-alike , maybe.:mad:
I personally would never consider stroking a 4G63. I think power can be had from other area's without resorting to changing internal dimensions. I also don't beleive in using nitrous , except as an external IC cooler.
I can not get any specs on Buschurs car. Is the engine mounted the proper way still? Or did he go the route of using a Starion tranny. I don't even know what engine he is using.

Rockinwrx is a moron. Magnus has had a stoker into the 9's.

And this makes me a moron how? I simply state fact , a stroker motor is more internally stressed. I welcome the challenge for you to prove me wrong. And 9's is not 7's......... far from it. Yeah , its real impressive for a stroker motor with more cubes to be just as fast a 4G63 block.:rolleyes:

Buschurs car is full tube chassis with fiberglass look-a-like body, RWD, and who knows what tranny.

Why bother wih the stroker when the 63 will do just fine:confused:

Sheppard is the man, stock appearing 9's :bigthumb:

Yes that car is badass

People use the 64 bottom end for the torque and obviously the added displacement. The bigger the engine is the easier it is to go faster with a tradition IC engine.

Plus have you guys ever ridden in a DSM with say a 60-1 under the hood? And not at the track, just driving it? If you have you know that the turbo lag is so bad you can't even drive the car. My point is that while the stock 63 engine can make some serious power, in order to do so you have to shift the power band to nearly above the stock redline. This makes driving the car almost impossible if not at WOT. A hybrid car equally fast would be easier and more fun to drive on the street. That's just one reason why the 2.4L block would be a worthwhile project.

And one more thing, I don't understand why people are criticizing those who have done engine swaps to make their car faster. I mean, have I changed what my car is by installing my 6-bolt? Do civic guys who drop an H22A change what their car is? No, my car is still a 97 GST and a civic will still be a civic (Granted a 220 hp one) ....But I'm assuming its okay to completely rebuild the internals and everything about the car to the point where nothing is stock except mabey the body (Otherwise Shep would not be running 9's) but as soon as you replace that stock block casting you've gone and ruined the car:rolleyes:

I know everyone has their opinions, but this "purist" stuff is just hippocritical. The only real purists are the all motor guys. Once you start modding your car anything to go faster is acceptable.

I agree with the comments on 'purists' but I also think that once you change your block for something not factory-fitted it's also unfair to compare it to other cars of it's original type

Dont know much about Honda type-codes, but if you fit a 2.2VTEC into an early Civic, it's not really comparable to other Civics of the time since they only go to 1.6VTEC

I guess that's only so much BS really [since this is the reason they split cars into classes for racing] but I see where ppl are coming from :icon16:

What's the difference between the g64b and the 4g63?

G64B - 2.4L SHOC 8V

4G63 - 2.0L DOHC 16V

does anyone know the g64b that works for the swap? Here are the ones that I found:

2.4L F.I. 12-valve SOHC 4 short block
(121/2" bellhousing)
2.4L F.I. 12-valve SOHC 4 short block
(131/4" bellhousing)

Van, Pickup, Expo 1989-92 2350cc G64B engine
2.4L F.I. 8-valve SOHC 4 short block
(Van)
2.4L F.I. 8-valve SOHC 4 short block
(Pickup)
Pickup 1993-96 2350cc 4G64 engine
2.4L F.I. 8-valve SOHC 4 short block
Expo, Galant, Eclipse 1993-00
2350cc 4G64 engine
2.4L F.I. 16-valve SOHC 4 short block (exc. 99-00 Galant)

I have done 2 stroker 4g63s so far and both have blown--dont try that at home---think it was a bad rod angle when the piston compression height is changed that much...

Anyway on to the 64b conversion...and for those of you who are needing the bulletproof swap and don't want to go to an older 6 bolt setup, check out speed design in godfrey, IL--they do a 7 bolt thrust bearing fix (no more crankwalk). These are the same guys that came up with the 4 spider center diff with a custom cross shaft and treated spider gears. I run one in my car and bulletproof like a welded one but the drivability is still there!

Thanks-
