Well so far my only mods are a boost gauge, k&n drop-in, and a RS-R 80mm cat back. Those mods were just to hold me over untill the real modding started, I wanted to wait a little longer for IX specific parts but I can't wait any longer. I'm selling the rs-r exhaust to a friend. Here is what I have planned for the stock turbo: EcuTeK flash, greddy 80mm titanium exhaust, RS-R 80mm downpipe, helix o2 housing, headers(still deciding), turbosmart E-boost II ebc, Helix intake, Samco silicone fmic hoses, Turboxs fmic(core only), HKS mivec 264/264 cams(when available), HKS cam gears, head studs, and a full valvetrain upgrade. So my question is would I be fine with 660cc injectors+ a walbro pump with those mods? Should I go with 720cc instead? What are my options with the intake manifold, does it need to be upgraded with those mods?

Edit: yeah I know the mods I want are a little odd but thats what I want

 

From what we have seen so far you should be ok without upgrading, pm TurboTrix and ask them what injectors they are running in their recently cammed evo9.

 

Shouldn't need injectors nor should you touch your intake manifold. I know you say those are mods you want, but that's gonna be a lot of money spent for little gain. As long as you don't mind spending more for less, that's fine, but I'd seriously rethink all of that...

 

wont need cam gears cause its MIVEC

 

Good to hear that the stock intake manifold doesn't need to be upgraded, I didn't want to anyways. I really don't mind spending the money if my car turns out the way I want it to. I want it to idle like stock and last a long time without parts giving me problems. Thats why I wanted the 264/264 cams.........is that the wrong thing to do? would 264/272 or 272/272 be any better? This is my street/daily driver car so I want cams that fit my needs in a street car. I also want to modify the stock turbo and put the 20g comp. wheel in for better flow up top for the new cams. So which mods should I rethink about? The exhaust? The EBC?

I like the exhaust I picked out because it sounds the best IMHO, I didn't want that loud annoying honda sound that most exhausts have. If you could reccomend a nice sounding exhaust other than the one I want then I'm all ears. Remember that I'm coming from a sti, which is the best sounding exhaust tone ever, so I NEED a deep/low exhaust tone. As far as the turbosmart ebc I happen to like it, I had it in my sti and it was awesome. I could be on the first setting running 20psi then with a simple press of a button boost 24 psi or even more with the third setting. I know it's $400-500 but I like the boost/wastegate control and many other features.

Still I'm open to your suggestions on my mod list, if it can help and give me more power than I'm all ears bro. I was shooting for 380-420 whp with a 8k rev limit..... I need the higher revs caught..17k redline on my bike..caugh

 

The real question is what are you trying to do? Will you road race this car? Drag? To what purpose are you doing the mods?

 

It's just a pure street car for street use. I don't street race, drag race, or auto-x/road course.....I just drive to work and other places. I know it seems odd but I just want to have all that power to use whenever I feel like it. Who doesn't enjoy a 4th gears pull while getting to work....plus I can't stand slow cars. My IX already feels slow and boring to me, the TQ is very unimpressive and to be honest it doesn't feel all that fast. I'm sick like that lol I always need more power.....

 

If you're doing all that for street use, then I am not interested in helping, but I'm sure others can help you. You will never, EVER use half of that power for any good purpose if it's just for tooling around on the street. Also, 264s and trying to rev to 8k with a 20g just doesn't make sense - they are opposite extremes, imo.

 

I wouldn't say I'm "tooling" around the streets. Anyways whats the big deal what I use it for? I'm paying for it so I'll use it any way I see fit, thats what makes all of us different. I'm not trying to go to the track every weekend because I don't want to be replacing drivetrain parts/clutch/tranny every couple of months after all this is my street car.....thats why I have the supra it's my pure race/drag car. Thats why I want to do "streetable" mods for my IX, I don't need another drag car.

 

It's funny that you assume I meant drag racing. That's not what the Evo is mainly built for either. It's built to go out and carve ruts into the ground while running circles around most others cars. You also shouldn't have to replace drivetrain parts/clutch/tranny hardly EVER when racing either. I don't know where you got that idea - I think it's just an excuse to not really use the car. You say "after all this is my street car," well so is my Evo, and so it is for 90% of us. It's smart to leave the Supra as your drag car, but the Evo is meant for so much more than trying to achieve 400whp just to tool around the streets...yes, it is "tooling" around, because you're certainly not doing anything else with it on the street.

Regardless, I didn't say you couldn't do what you want to do - I just said I am not interested in helping you achieve your goals, because I think your goals are useless. That's just my opinion - you don't have to like it or agree with it.

 

I didn't say drag racing.......read what I said, I'm not using my evo for drag racing/auto cross/ or street racing since I already have a car specificly built for that. I haven't even launched the evo yet, it's not a drag car that why I don't use it for that. I use the evo for daily driving and hitting up the canyon roads here in southern California with the local sti guys. I need and want 400whp for that reason. Listen you may not like it but all my cars/bikes are fast, I want all the cars I own to be fast regaurdless of what I use it for.....I'm addicted to power. The slowest car I have ever owned was a wrx. Thats just my style, I need to have a fast car or I won't drive at all.......I'm sure I'm not the only one with a evo who wants more power in their daily driver. Thanks for the help I guess.....

 

To acheive a reliable 400whp your gonna need a bigger turbo...say a GT3071 or 3037+ on race gas or alky.

 

I want to avoid race gace and water/alky injection, also I don't want a large "laggy" turbo that only has a peaky power band. I want to have a lot of power through out the entire rev range. I mean I'm not exactly looking for 400whp, anything in the range of 380-420 is what I'm shooting for. I think 360-380 whp is more realistic for me since I will be using our famous CA pisstane. So do I still need such a large turbo for that power? I was thinking about a 50 trim turbo if it spools fast and give the powerband I want. Thanks!
