swaping engines

[BlueClipse95]

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?

[RockinWRX]

And Its actually preferable to swap for an OLDER engine. Namely the 89-92 6-bolt motor 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 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 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.

[Talon007]

Umm why

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

[aves911]

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.

[RockinWRX]

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..............

[kjewer1]

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 I know on Shepperds 9.3 he said that he no lift shifted at over 9500 rpm. Hmm...
