SW Sport Pilot

Good evening all

Wondering if anyone on here can give my friend some advice, he has just purchased lovely Evo 6 and has decided to coax some more power from it. It has just received a Full service including belts and AYC.

He has just bought an apex AVCR, Aeromotive fuel pressure reg, walboro fuel pump and a brand new Evo 9 GT turbo apr strengthened rod bolts to go with apexi induction kit.

With this fitted and a ecutek remap he has been told that a usuable responsive 400BHP will be achieveable

What he wants to know is there any known weaknesses that will show them selves when the car hits this sort of power and associated torque

Cheers guys for the advice

maybe he could try this forum buddy... i'm sure someone could tell him the best and worst ways of power extraction...

He is already a member of the MLR but in his words they are a "Bunch of big headed idiots that are tight with info and a majority think they are better than every one else because they own an evo"

he's hoping that some of us will be able to help him

Cheers

Thought I'd bets show my face, I'm the evo owner taht is duely unimpressed with MLR. Thanks for all the replies. Weirdly I am a member of evonet yet I haven't ever posted on there. Best I look once it comes back on. When I had my rover ppl were very forthcoming with info about tuning, which is amazing really when you consider that not many ppl ever tuned a rover as far as I did. I thought Evo woudl be simple as there are quite a few tuned ones out there, infact just about every one of em has some kind of mod to it.

Oh well, thanks for all yer help so far, at least I got replies on here, I asked on MLR what I should be thinking of to go with the above mods to make it a stable car taht wasn't gonna blow up on a daily basis, expected ppl to say get a better diff or uprate your gear box. But no replies at all....not even a pointless one. Comes to something when you get more replies about an evo on a subaru site than what you do on a dedicated evo site !

I've had trouble on the MLR as well, mainly from upsetting substandard tuners and their followers with details of how to do it better with open source remapping tools (unfortunately not yet ready to do the VI) and exposing poor workmanship.

I've not tuned a VI, but from what I know you've covered most of the bases as long as you have the later batch of IX GT turbos that has a more robust compressor wheel as the earlier ones failed frequently. You may have trouble with the AYC if you run a lot of torque. Pistons I gather are fine. Cams might just hold you back from 400 BHP, but it will be near enough I think.

A workmate of mine has just tweeked his evo6 to the 400mark using a few extra ingredients tho,

Autronics ecu mapped by NR @ 1.6bar
Tubular exhaust manifold
Cams (not sure which manufacturer)
Vernier pulleys
Full turbo back 3" zorst
Modified evo9 wastegate act'
HKS filter & hardpipe

There were a few extra bits but these were for piece of mind rater than performance, other than this the engine is amost standard & being used daily with no problems yet.
Hope this helps.

scoooby nut

the weak part of a 6 is the rods and some times the pistons depending on how much boost you run if he wants close too 400bhp he may aswell forge the bottom end

you dont list any exhaust mods it really needs a 3" straight thru and a decat.

mlr is great cant see wot the problem is iv been a member for some time now and have owned 2 evos as well as 2 scoobys.

if u need any more help or even some nice new hks parts do a search for me on there and drop me a pm my mlr user name is : next_best_thing
