How's it going guys I plan to start modding my Evo next month, I was thinking of doing my builds in 2 stages and would appreciate any help and recommendations as far as parts, companies, and all that.

Car is a 2015 Evo X Final Edition.

First stage would be just full bolt ons and a E85/91OCT dual map tune.

Second stage would be upgrading the turbo and other components that need to be upgraded as well to keep the car as reliable as possible.

My goal is to be in the 400s for both whp/tq if possible.

Mods so far is just a ETS intake that was installed when I bought the car.

Thanks in advance!

 

It will make 400wtq and high 300's, maybe 400whp on the stock turbo with E85. MHI 18k with proper fuel system will do about 475whp.


An ETS turbo kit with a Precision gen2 5558 or a 5858 will make 475-500 on pump and 575-600 on E85.

 

Interesting

 

Damn that is crazy! I forgot to note that my evo is a daily driver. So that being said which would you recommend? If I were to go with the ETS turbo kit, that would be on top of all the bolt ons to make similar power to what you said correct? I know the stock block is capable of 400tq while remaining reliable, but if I were to be pushing above 400tq what would I have to do with the block?

 

Don't think 400wtq is the end all be all. It's more where the torque hits. There's a difference between a stock turbo hitting 400wtq and a 5858 hitting 400wtq.

 

I'll agree and raise you "it's also how long the 400wtq lasts".

I can tell you from experience that my Evo 10 that stays over 400wtq from 4800 rpm to 8400 rpm is a MUCH different experience than the stock turbo hitting 400wtq for less than 1000 rpm.

 

You’re implying the stock turbo hitting 400wtq is worse than the 5858 because of the quicker spool I assume, right?

 

I wouldn't say it's worse. I'll say the stock turbo hitting so hard and so fast at such a relatively low rpm has the potential to do more damage than a larger turbo hitting 400wtq at a later rpm; even if the larger turbo holds the torque for longer.

 

A turbo kit will be more reliable than any stock frame option due to reduced back pressure.


As has been said, 400wtq isn't the end all be all, its where it comes in.


And don't assume 400wtq is reliable. You have 10/80/10 rule that applies. Some car blow up at the generally accept limit, some cars last, and there are the ones that people push the stock motor really hard (450wtq+) and it manages to live.


I would say the most reliable setup will be the turbo kit on pump gas in the high 400's range. It will be (relatively) low boost; so charge temps will stay low, back pressure will stay in check, and you won't be pushing the window for torque. It'll somewhere in the mid 300's for torque. And the fuel system is easy. 1100cc injectors, and a drop in ASNU fuel pump is all you'll need.

 

I have fbo , mhi and flex fuel and I'm very happy with the results 450/370tq, however...
if I was to do it all over again, I would have saved up for a turbo kit for all the same reasons as mentioned above. The cost is pretty similar all in, just with bolt ones and upgrading stock frame it's easier to spread out the expense in stages.
