Okay so here is the deal... I've been trying to sell my corvette so I can buy an evo. I've found two evo's that Im really interested in, both evo's are completely built however one is significantly more powerful then the other. I got a call on my vette and the guy asked why I was selling, I told him I found a 900+ evo that Im interested in... almost immediately he said not to buy it, he said that when you start to get evo's running really high horsepower they tend to not be all the reliable, that the break really easily, and aren't meant for street use and are mainly a track car. He said that its extremely difficult to get a good tune for a car like that which is the cause for such concern... he also asked if I knew if the block was "filled" or not, Im not really sure what this means... is any of what he said true or is he just trying to get my not to buy a car that would be faster than the vette I might sell him...

here are some of the details of the evo...

PTE 6766
ETS 3" intercooler piping
ETS 5" intercooler
ETS 3" turbo back exhaust
Aluminum intake manifold
70mm throttle body
FIC 2150 injectors
2.3 stroker
Extreme tuners 13:1 CR pistons
Exreme tuners custom rods (tool steel) supports 1600hp
Extreme tuners balanced crank (tool steel)
Extreme tuners cams (270 intake 290 exhaust)

He also said it has a built trans, built Tcase, Quaife center diff, stage 5 axles rated for 1400hp, exedy flywheel and triple disc clutch, the car runs on E85 but hes running the AEM V2 EMS with multiple MAPs for 91, race gas (which is sold at a local gas station where I live lol) and meth, It also has AEM UEGO wideband and AEM E-BOOST and he's running speed density as well...

Does this sound like a car that I would be able to drive on the street everyday with no issues? Would I be able to take it on long trips?

Thanks in advance!

 

here are some pictures of the build, not sure if they would be useful or not...

 

Considering david buschur runs his as a street car eith a bit over 700whp idk what that guy is talkibg about. Of course locally there are a few guys with arouns 450whp and their perfectly fine as a dd so I can't speak personally for over 500 but I dobt see why the reliability would drop if everythibg is done correctly it should not matter

 

Reliability is in your hands! High horsepower cars will break down in the hands of the abuser! Don't skip on maintenance and take care of the car and it will be just as reliable as stock. I do not know why. But I tend to see more problems with closer to stock evos then high horsepower evos

 

Raising the power level of any car makes it less reliable period. When a car makes more power its under more stress and therefore is operated closer to the physical limits of the car/parts. It's not unheard of to drive a high hp car on the street, but a 650hp +evo on the street isn't anywhere near as enjoyable as a 650+ mustang or whatever.. In general it'll only make big power up top, and will generally feel like a slower car. Nt to mention that if it makes big power i assume it has a triple disk or comparable clutch, solid mounts all round, and big cams, nine of which are conducting e to driving on the street.

If you own a high hp evo, then you should either know how to work on it yourself or be prepared to spend a lot of money on it; because when/if something breaks at high power levels it's usually expensive/complicated. You should probably also have a second car if you don't already.

It's the same reason why mostly stock evos "break" all the time, because the people that own hem don't work on them and therefore don't know how to, so they dump it on a shops lap and just say "figure it out". I don't know you so I don't know what your auto knowledge is, but it's generally a better idea to build a car yourself piece by piece and learn how to drive/ operate it then to just buy a race car.

Are there not also several threads on this forum about the questionable claims of extreme? https://www.evolutionm.net/forums/al...evo-build.html
It starts there I believe and continues with an awesome and hilarious freak out from some Evo Gods. If you follow enough thread links.
You said there was another car to look at?

 

A lot of what that guy said sounds right. In answer to your questions above, I say no.

If you want decent power along with reliable daily driving, I'd stick with built Evos making around 500 AWHP, maybe 600 tops on high boost. That's kind of the Evo sweet spot from my experience. Shoot for a stroker and something around the size of a 35R- preferably twin scroll. This will also be fun to drive in town, compared to a lag monster. And yes, pushing 900+ is asking for things to break often, so I wouldn't bother in your circumstance.

 

13.5 to 1 CR is definitely not a DD.....

 

Hey guys thanks for all the input! Yes there are two evos that I'm looking at, the 900hp one and another that has 503hp

 

I'm not sure what you got out of the input. However, If you know nothing of the evo platform, I would highly recommend NOT getting into a high hp Evo to start... But thats just my .02

 

Lol not to be rude but how do you expect to operate a 900+ vehicle if you need to
Start a thread like this, I'd start asking myself is this the right car for
Me..

 

Just walk away from that evo. find another one. For an evo with 13:1, 91 octane shouldn't even be an option. That motor should of only ran on e98 or race gas. If you car looking for a DD (driving everyday) I'd stay under 500hp. High hp usually = weekend warriors

 

My current car is a 800hp corvette z06... you shouldn't judge someone just from a question they ask, I'm just looking into getting something that's AWD since I live in ND and I only get to drive my vette a 5 months out of the year when there isn't snow on the ground

 

so you think you'll be able to drive a 900hp evo an additional 7 months?

 

Yeah seriously. Not judging you OP, but if you think having 900awhp is going to be a year round car. You are very mistaken. Hell a 400hp evo is a lot for snow.
