i dont know about that, he built the engine and tuned it, and i followed all his instructions on engine break-in and what oil to use.

all i know is, he couldnt tune so he disabled the knock tables and my engine was done.

@klaiceps..i guess im just unlucky maybe, but from what i,ve read on this forum, if your 4g63 is at 500-550 hp range its reliable, as you go higher it gets more and more prone to failing cause really how much can you expect from a 2 liter 4 cylinder engine?

i remember a thread here a few months back where a respectable shop says that making 150 hp per cylinder from a 4 cylinder car is too much and things fail.

plus i have yet to see a high hp evo that has 700-1000 hp that is reliable and keeps on going for years on end and has no problems at all, you all ways see these threads on here with people who have build threads and show all these fancy pictures and high hp dyno numbers and all of a sudden you never hear from them again and the thread goes cold because they make a 700-1000 hp evos and after doing a few thousand miles something happens and i bet if you really beat on it with the mentioned HP range it will last less that 3000 miles, again because what can you really expect from a small engine. you have this little engine with a big turbo slapped to it and 40+ psi of boost what do you expect will happen? the bigger the engine the less load and stress it has. on the other hand if there is a high HP evo which keeps on running for years usually they are shop cars of vendors and thats diffrent because everytime something breaks or engine fails they replace it with a new one, thats not reliability, thats just having lots of money lol.

im just looking for a stock block now and will be happy with 450-500 hp, and see how long that lasts, fingers crossed!

 

I guess enough could damage the bearings. Still sucks, man. Good luck on the new build, though.

 

if you are doing remote tunes i would highly recommend contacting TSCOMPTUNED he is a really good tuner.

 

Maybe that video I posted was not a prime example of reliability, but rather the strength of the 4G63. Anyway...

As with any build, no matter the engine, it will come down to the mix of parts, the shop that assembles the motor, the tuner, and lastly, your right foot. If you get the first three right, your motor is golden. Your right foot pretty much determines how long you want the motor to live. Hell even Honda motors with their reputation to be dead nuts reliable don't last long once it enters a racing environment.

 

yes my right foot is very conservative, i dont beat my car or drag race red light to red light at all, but ive been very unlucky that both my engines didnt last more than 600 miles.

both failed in the tuning process, one due to tuner, the second due to a timing belt failure.

 

If you're looking for a good email tuner, hit me up. No need to wait months nor break the bank. I can help point you in the right direction.

 

ok sure, as soon as i get my stock block ill message you.

 

You will see my car in the 700-1000whp range soon here. I am going one step further and running a 64 block which people complain about all the time. Yeah its not going to be stock, but it will handle that kinda hp. As for one on a stock block honestly its kinda stupid being the stock rods are tooth picks and without proper tuning they will snap easily. Another thing you have to remember too is, most of the people who run that kinda hp don't daily drive them. Most of them see the track more then the street. My car will be a street car and yeah it will be as close to 1000whp as I can get with a s369 and I will drive it everyday. Why you may ask? Because I can lol. Car is ready to go get my new motor here soon so it shouldn't be long.

 

as far as the stock block is concerned, its the only thing i can afford right now lol. i just want a car that is running, right now its without a engine. like i said before i have had two failed engines which cost me combined over 12 thousand dollars if you count the shipping and taxes in my country, i cant afford to have another one fail on me so for now just stock block. if this block serves me well, down the road i might get another built block. this is why i was questioning the reliablity of the 4g63.

and about running 700-1000 whp on your new build, i dont know why but i have doubts, yes you will make 1000 whp, but the reliablity will be zero. it will give way anytime, all that i have read on this forum and other forums say if you want a reliable evo dont go over 500 hp.

i dont want to jinx you but a 4g63/4 with 1000whp will last you maybe 20-25 passes at the track and maybe a few thousand miles on the street if you dont beat on it. i just cant see a small engine producing that much power safely.

how many people on this forum have 700- 1000whp evos which are still running after a few thousand miles? i dont know anyone.

like i said if you have money and throw in a new shortblock everytime the engine goes bust, than that is something else and not reliablity.

i wish you all the luck though, i will message you after a few months to see if your engine is still intact.

 

and by the way i just wanted to know, are you still running the balance belt or you have removed it for the stubby shaft?

 

Oh. You'll see. 😀

 

It is all about tuning my friend, I have spent extra money on all the coatings I need to keep things safe, I did not run oil shredding being for what I will use the car for (daily driving and maybe a track day here and there) its really not needed. I will be the first to say that I really don't care what people think or say on this forum. They aren't the ones spending 1000s of dollars on what I am building. I know what I am building, I am letting someone who builds 1000 hp evos, dsms, supras, v8s all the time, its what he does for a living so I tend to trust what he does. Hell he has a customer that made 985 whp on a mustang dyno and after 8 years the motor finally gave out and he killed it driving to the track at posted speed limits lol.


It is unfortunate to hear you have wasted so much money and had no success and it pains me to read that it really does. I have been in the 4g platform since 98ish and I have had plenty of 400-600 whp talons and evo, they are plenty strong as long as you do it right. My new motor is an all e85 motor that I do have the ability to run pump gas if I wanted to even with high compression. Most people who have that kinda power have only track cars, I know a few who do drive them more then track them and so far no fails. Hell David Buschur made over 700whp on his dyno and he daily driven the bad bish for how long? Yeah he blew it up a few 100 times but for the most part it stayed together as a street car.





No my balance shafts will be deleted. They have been doing that for 20 years and I don't buy the oil pump failures being I have never had one fail at all. Only time I have seen them fail is when people refuse to get new ones or freshen up the gear and shaft.





Lol I will see 105 to 112 lbs per min from my turbo lol

 

exactly.


our subby shafts are OEM, though i forget which car it's from. they don't seem to have oil pump issues. i can't imagine a stubby shaft causing much of a problem, though i don't know the differences between our pumps and the one the stubby shaft comes from. so far, so good, though.


oh, i have no doubt about that.

 

If memory serves me correct being its 4:15 A.M. and getting ready for work it came out of the Starion.

 

can anyone tell me if evo 6/7/8 block is the same?
