Hey everyone, im looking to see what are the best mods to make your evo last longer, whether its the engine lasting longer, to the tranny . basically anything to help prevent problems. Please not obvious things like oil/fluids.

Such as, would building the tranny with lets say a 'shep' make it last longer even if its for a DD?

or things like building the engine.

----& lets say the car is stock besides bolt ons, stock turbo on the 8/9/10.

 

I've been wondering about the advantage of using a Fluidampr Pulley instead of just using an OEM Pulley on a stock motor with one or two performance mods.

Anyway, if you have an aftermarket air intake I would recommend using the AMSoil dry flow air filter. It will keep more crap out of your motor.

 

This is just one man's opinion, but the EVO, especially in stock or bolted-form, are still overbuilt. The best "reliability" mod you can get is a tune. From there, the air filter mentioned above sounds good but otherwise, the obvious stuff really is all that's necessary. What is your goal for the car? If you're looking for a 500 awhp car to be as reliable as a 300 awhp car, that's a different story.

 

Really? Nobody is going to tune your Evo safer in a couple hours than the factory. It just doesn't work that way. Completely stock is the safest.

 

So running 9.8:1 AFR on the factory tune is the best thing for reliability?

A tune doesn't start from scratch, it builds from the factory tune so in most cases you don't have to touch very much at all unless you've upgraded several items, injectors, pump, etc...

Factory tunes are **** and are meant for Joe Knownothing who doesn't change his oil often enough and might put 87 octane in by mistake. Don't kid yourself.

 

what about a gates racing timing belt? head studs?

I bought what I perceived to be the best made stuff. that's been my strategy with my modded WRX which still runs like a champ after 5 years with an extra 100 HP.

- all my work done by highly regarded installers (or me)
- all my parts from the best in the biz (except perhaps my prosport gauges which won't affect how the car runs if they fail).

the car just runs right.

 

well im just trying to see what people do to their cars and if they have had success to help other people new to evos! thanks for the advice guys

 

I was a bit harsh up top. With that said, just reading through the tuning forums as I was teaching myself V7, I know I came across accounts of stock tunes producing 7+ counts of knock. I don't consider that to be very reliable but to each their own. There are literally thousands of untuned, unmodified EVOs running around without issues so I shouldn't say the stock tune is garbage, but it can be improved upon without affecting reliability in a negative way.

 

i believe headstuds is the most common one..maybe a kiggly hla for the turbo. fuel cut set at like 7500.. etc

you mentioned a built trans in the OP but isnt that the kind of thing we're trying to avoid? A lot of this reliability talk depends on power levels and usage.. stock power, trans etc will be fine

 

clearly this guy is trolling, or is completely clueless and should never be taken seriously.

 

evo 9 dv vs. evo 8 dv
underhood and shifter base bushings
boost gauge
wideband

those are a few mods I can think of that I would consider mods that can improve reliability.

 

To me! Reliability and mods dont go hand & hand, why ? You start modifying something that was not designed for the car, it takes time & money to design and built a car to be reliable so it can last 10 to 20 yrs. If you want the car reliable and to last you forever leave it stock, although there are evos making 400hp for years but you never know. You could make 500hp and last a few years or make 300hp and last you a month.

 

Solid advice right here.

 

no i agree with you guys about mods, however im not saying throw a big *** turbo in it and make it last 20 years lol. by mods i mean what things can you add to the evo to make it last as long as possible which DD it everyday.

 

what im saying about a built trans is it if it is built well , and is Daily driven will it make it last longer ? since its built for a beating right? so babying it must make it last longer then a stock should.
