Hey all -

Back in February I got the following bolt-ons: ETS intake, ETS Quiet V2 exhaust, and Grimmspeed 3-port and tuned by IveyTune.

I ended up making 321whp/313wtq and it definitely livened up the car; it's a 2011 Evo X GSR. I'm starting to get the mod itch once again.

Based on your experience, what would be the best bang for the buck for HP/TQ mod wise? I'm thinking if I do anything I'd want to replace all intercooler piping, intercooler, downpipe, etc. Not sure how I feel about a high flow cat or testpipe due to inspection and what not but I assume that this could be easily switched out.

My only thoughts are I'd like to try and keep the car as reliable as possible and for it to pass inspection if I do keep it for another 3 years . Right now the car is my daily driver ( I do have a 2001 accord at another location as a spare car) and I'm trying to prevent causing myself isssues.

Any advice/suggestions? Thanks.

 

I have an AMS UICP, IC, intake, Cobb TBE, 3 port, and tune. I had pretty much the same hp 336 but I had 361 TQ.

 

You mean you had the same mods I had and then got AMS UICP and intercooler and but gained more torque? Little confused by what you mean.

 

Bite the bullet, go with the test pipe just keep the cat laying around and put it back if needed for inspection time. 3 yrs out, might as well have fun in the mean time.

 

See my sig and you will notice that even with some additional bolt ons the power increase wont be substantial until you either go with E85, upgraded turbo or both.

And this proves exactly what I thought. I'm thinking best idea would be to go with a map EF2 turbo and supporting modifications, and I'd be happy. But I think I'd start to be sacrificing reliability at this point since that would bring the car around 390whp-400whp.

Hence my dilemma.

 

Im in the same boat as you man. I want more power but dont want to risk reliability or shell out all the $$$$ for a turbo and subsequent parts.

In the end, I know I will end up going with a bigger turbo. Not sold on the E85 just yet.

 

I wouldn't go for an EF2 or FP turbo, they are starting to stop production on them because they are unreliable. You will be fine on a GSR with a that much power without issues.

If I were to get a new turbo it would be the new factory upgrade turbo just released by Mitsubish:

I assume you meant to say unreliable? If so, that's quite a broad statement to attribute to just the turbo's themselves. A quality tune and supporting mods in conjunction with either of those turbos can be reliable. Will it be as reliable as a stock car? Obviously not, but anyone who modifies a car understands that the more they push the motor the more likely things are to break.

Since the car is your daily driver there is no NEED for an upgraded turbo. 300+ whp is plenty quick for the street and is faster than most cars. Just my 2 cents.

 

Took the words right out of my mouth. Very well put.

 

More is better

 

Exactly. Trust me, the car is fun as it is but with all things, once you get used to something it gets boring to an extent. I'm not looking to break 1/4 mile records with my car but I would like to make this a mid to low 12 second car. I'm not saying that I would be able to run those times but that the car would be capable of running a time in that range.

I've done some research and I'm wondering, what kind of power on average is necessary to get an Evo X GSR in the low to mid 12s? Please don't flame, I've been slowly trying to get this car to what I had with an Evo 8 in the past which was a high 11 to low 12 second car.

 

Im not proffestional but Im sure if you ran E85 you could post some mid 12's.



Not sure your feelings on E85 tho

 

I assume that I'd need new injectors and pump for E85. Not sure what my options are for E85, location wise. With that said, if I was going to get injectors and pump, I'd probably just want to do a little more like turbo back exhaust and intercooler.

Ultimately, I'd like to stick to 93 octane fuel wise for now.

 

I was saying I have similar mods but I also have an IC and UICP. The guys at Cobb tuning said you don't see a huge gain from an IC on a dyno but the real gains are seen while driving on hot days. Maybe get one of those.
