Max horsepower on 91 oct(bolt ons only)
Fellow members
I am planning to upgrade my Evo 9
I would like to hear from those people who have done it.
Here is my plan
Goal max horsepower (dreaming of 500whp
) bolt ons only
Use street, occasional drag racing
Shopping for new turbo kit (GT3540 preferred or better) too laggy it's ok
upgraded walboro fuel pump
new injectors (any suggestion 750-800cc?)
apr head studs
apr rod bolts
Custom tune
hks exhaust cam (intake cam available yet?)
Already have exhuast system and kn filter
exedy twin clutch
water injection kit
No NOS, no methanol, no race fuel. ok maybe 93 octane on track
Members suggestions would be greatly appreciated? Should I stick with my stock turbo since I am using the car mostly on the street? Am I wasting my money getting a new turbo?
Vendors pm me for package suggestion.

Sorry, but you're way past "bolt-ons" with that list. The moment you put on a GT35, the term 'bolt-on' gets thrown out the window. Yes, you are wasting your money on a GT35 if you don't plan on using the power. The stock turbo can give you 400whp/400wtq with 0 turbo lag all day long...

I don't know, 500WHP on pump gas (no Meth) with GT35 Turbo would be tough, for any EVO. I mean, that turbo really starts to make power at higher boost levels. I believe it is possible, but not with your mod list, you'll need more, maybe a stroker kit could help, your gonna need upgraded FMIC and Pipes for sure, Intake Cam is available from Turbo Trix, some excellent tuning. Possible, Yes. Easy, No. Expensive, Yes.

I would love to be proved wrong though. Either way, there isn't enough data here in California yet. I'd like to see what a 9 can do with both cams upgraded and all the usual bolt-ons.

Water injection doesn't make much more power that I have seen here in Cali, just makes tuning to the ragged edge much safer.

Cali weather is also hot. It is hard to boost more than 20psi without few knocks on stock turbo. I doubt you can do 400whp even with Alky using the stock turbo here. you need the big turbo with Alky to go more than 400whp in Cali.

well well well. big turbo + 91? not happening sorry. you won't even be able to spool a GT35R on 91 octane. maybe you should max out the stock turbo & see how close u get. u won't get 500whp & HP is not what gets u down the road. TORQUE is!!! alky injection is working very well for a few members in AZ where it's hotter & drier than Cali so u just need to look some more. there's even a guy in Tucson making good power running water/meth with 87 octane!!
since you have a 9, why not take advantage of it's stronger points instead of modding the honda way & yanking everything off for a big turbo? everybody seems to want big turbo power but not all the goodies to go with it. then they make 500whp & blow the motor in 3 months.
