hey guys

ive had several evos 8s and 9s i know the 4g63 well

now looking at buying an evo X

i searched and couldnt get a straight forward answer what are the limits of a stock Evo X block.

Im looking at a used 08 upgraded turbo stock motor stock cams stock head studs.
car is making 452whp and 352wtq on a mustang dyno at 27PSI on E85

want to know if this setup would be reliable i understand its all about the tune but is it posible for a stock motor to handle that much power for years upon years?

which was done by brian at GST a few years back.

the wTQ is low at only 352 and from what i understand TQ is what is really hard on a motor.

let me know ASAP

thanks in advance

 

That's about max HP for what's on the car. Might wanna back that down a little to around 400 until you can upgrade a few of the parts. Since it's got an upgraded turbo, you might wanna check and listen to see if it's making any loud noises. Stock turbo's make a decent amount of turbine noise when spooling. Also, the reason to back down on the HP is that your tranny won't handle much more and if it's got a stock clutch, it's prolly fried and that's why the WTQ is so low, just needs a stage 2/3 clutch to handle all that HP.

Also, you might want to find another car since that one proly had more upgrades on it before he stripped it down. It's better to find a more "stock" car that way the engine will be less abused. It's up to you though, My used car was in good condition but I've had issues with minor things, nothing major, like tranny or engine problems.

Also, buy it from a dealership, that way your covered if the car breaks down after only a couple of days of owning it, plus you can get an extended warranty to help cover the car.

This is all just IMO and doesn't mean you have to do anything I say haha

GL with your search, heck, why not buy a brand new 2013? haha yeah I know, it's over $40k haha

 

too many variables to give you a straight yes no answer here but i'll throw my .02...

that much opwer on stock motor/tranny can't last too long. but it really depends on your driving habits and how well the previous owner took care of the car. "taking care" of a car is different for everybody. for example, my friend with a 94 supra tells everybody that he takes good care of his car. what he means by that is, he changes the fluids regularly and keeps the maintenance portion up to date. i tell him he doesn't take good care of his car because he has the tendency to go wot without waiting on the motor to fully warm up. he also likes to free rev (not good) a lot.

used cars are hit or a miss. in the end, you have no idea how much the car was cared for or how much it was raped by the previous owner. my 08 gsr has 80k miles with stock clutch and stock chain. no problem so far... the car is making 280whp and 280wtq on dyno dynamics and i've had this setup for about 60k miles.

i'm not going to discuss the chain. 08 with that much power, i'm guessing the chain is either already replaced or is about to crap out on you. check the chain before you buy.

good luck with your purchase. you won't be disappointed with the performance of this car. especially with that much power.

 

515.21 Nm, anything more and she'll blow!











no seriously, No one can do more then ballpark it for you without datalogging it and listening to it, but it sounds like it's pushed to what is considered the standardized limit of the stock block safety mark.

Most of the decent tuners suggest torque as the killer and 380ish being the start of "Danger to Floormats". If everything checks out sound on this car, maybe backing the power down to 400hp and 350ish torque like someone suggested is a solid recommendation if you just want longevity, but nothing is guaranteed.

 

what do you guys mean by the chain?

do these cars have a timing chain compared to a timing belt?

also anyone have anymore input?

 

4B11T has timing chain, not belt. There were problems with 08-10 with chain stretch happening. There was no recall on it, however the very late 2011 and 2012's came with a redesigned timing chain that had a new part number.

 

what he said.

 

Most users have not had any problems with the timing chain. Once a few members have the same issue pop up, it turns in to "a lot of cars" in those years and everyone worries about it..

Anyway, yes the torque kills parts and that's why the torque is so low.. 370ish tq is about the max you would want to run on stock stuff.. Over that and it can get questionable. It's all about the tune and how you drive it though. Some people can burn through the stock clutch in 10k miles and they say the clutch sucks.. While others that have driven Evos for years, like me, use the stock clutch for 50-80k miles.

I wouldn't buy it if you don't have Atleast 5-6k laying around. It's not smart to buy a used high performance vehicle that is loaded on power and modifications and have no cash left just in case something decides to let go.. Not saying it will/would happen, but..

 

the fact that mitsu redesigned the chain tells you that its not an isolated incident that happened to a hand-full of people. it was a problem big enough for mitsu to step in (sort of...) and make changes.

 

Alot of stuff changes.. And yes, it needed to be redesigned.. But what percentage of users with '08s and '10s have had timing chain issues.. Less than 5%? Maybe even less? Like 3%

It's an issue, but it shouldn't be a determining factor to buy an Evo or not. The timing chain issue is exaggerated on forums, just like other issues that come up.. Not saying its not something to think about, but it's just not as big as some make it.. That's all I mean.. All cars that use timing chains are going to have cases where the chain stretches. That's just part of it. Mazdas had a lot of issues.

 

In all honesty getting worked up over chain stretch in this decision is a pretty moot point. The fact that the OP is considering buying a car that most of us by a sense of averages and forum posts consider "near the limit of the stock block, but at a safe margin" , I think the ending focus we leave is exactly what kirk said.

Don't blow your cash wad on this car. If you can buy it and have some safety-net of cash sitting around to be prepared for up to a rebuild, then it sounds like the way to go. If you are buying this car and have nothing left, Murphy's Law might make you have a bad time and a bad impression of the platform. Really the decision everything to do with the OPs financial situation and that's beyond the scope of this forum IMO.

Good luck OP. Hope it works out for you with this one, or a different X. They're fun cars and we'd like to see you join the community.

 

looking at you previous car list on your avatar, it seems like you have had some kind of experince in the past, so knowing what high TQ does to your engine should not be news to you. People underestimate the 4b11 but the engine is pretty solid belive it or not, there have been plenty of threads where people have made crazy power on stock 4b11...look them up, i think ETS was the first one. Timing chain is a thing i have heard once or twice out of 10000s that have bought the car, so dont belive the hype and dont let it scare you. I have seen more timing chains fail on newer hondas that i can count, AND hondas are "reliable".
The power the car is making i would not worry one bit, if you like it go for it. thats nothing for that engine IMO.

 

Mitsubishi made slightly over 2000 cars in 2008, 2010, 2011, 2012 each year. They are expected to make about 2000 for 2013 as well. Fact is the Evo is not common.

I have not seen a single person here in the NTEC club, which is the second largest EVO community in the U.S. with a timing chain problem. there are people out there that have ragged the hell out of their cars and then blame Mitsubishi when it fails, You drop the clutch at 5K RPM and yeah the timing chain is going to get jerked really hard... and it could stretch. Yes Mitsubishi did upgrade the timing chain, they have upgraded lots of parts, many that had no issues. Don't let this be a factor.

As far as power goes, its all about the quality of parts and the tune you get.

I have over 450 HP and right at 400 tq to the wheels, its daily driven with 55K miles.

There is a moderator here in Dallas that has 45K miles pushing over 400 hp and similar on tq on stock clutch.

Any car will last as long as how well you treat it.

 

I have 470whp and 360wtq tuned by English, FP Black BB, Cams, and much more, all on STOCK BLOCK, and nothing has happened. I have the oil changed every 3k miles and make sure everything is good. I do WOT about once a week.
I have ran this setup for about 10k miles/10months.

I do have an aftermarket clutch, but that's because I need it to hold more power... and I killed the stock one because I did a bad launch......

 

pretty sound advice
