I love the Evo, but mine is stock and I'm ready for a bit more power. On the other hand, I'm not ready to throw 6g's at it at once. I've ordered an exhaust, and an intake, and I wanted some opinions as to how you guys would structure out further mods. I was thinking I'd go with a boost controller/EMS next, but maybe someone has a more practical "next step."

 

S-AFC?

 

in/ex CAMS upgrade is not a bad idea.

 

Depending upon how far you want to go power wise, any of the reflash/advanced piggyback options available would work great. Moving to a full standalone like the EMS is a major financial commitment and in some ways could be overkill altogether considering the comprimises you will have to make as far as not being able to pass Inspection sans OBD2 as well as possible A/C and cold startup probs which would have to be accoutned for. If you're not worried about warranty all that much and simply want a fast reliable, and relatively cheap to build street car simply pick up a full turboback, some type of reliable boost control, a set of HKS 264/264 cams, Walboro 255LPH fuel pump, and finally some type of fuel management.

 

Even with just an exhaust, your next step should be a piggy-back or reflash. Proper engine management can tap more of the potential built into your car.

 

Thanks for the input so far. I suppose, per Fury656, it would be helpful to note that he's right in assuming I don't want to build a drag monster. Ultimately I like big power, but I don't want the car to drive like garbage when I'm not gunning it, and this is my daily driver, so.

Also...won't the cams fail in an emissions test? I know you can swap them back out and all, but maybe you have info on the 264s passing? Coz that'd certainly be good news.

 

Even installing a test pipe will fail the emission test. What's the point here?

 

If it were me.. I would just go Vishnu stage 1.

 

Same here. But not yet. Still saving and waiting for the baby to come out.

 

Well, I think the point is hassle. It's probably less hassle to swap a test pipe and cat, were I to bother doing that, than it is to mess with your cams. I will very likely run with a cat, anyway, so the comparison isn't really a good one. Also, it doesn't answer my question. I've said I'm not building a race car, so it's pretty important to know what mods do and don't fall within legal limits. And should I choose to ignore said limits, that's on me.

EVO Enthusiast: Vishnu stage 1 did look fairly attractive to me, but part of me enjoys the personalized aspect of not going with something that's wholly prepackaged. I realize this necessitates custom tuning later, but that's sorta part of the fun.

 

I will get slated for this but I’d get a standalone after the intake and exhaust has bin done. 375bhp has bin achieved from an EVO with an exhaust, filter and Gems ECU (I think you guys call them AEM). Plus, with any future mods you will be able to set the ECU to get the most from them! Just my opinion and most will say you can do the same with the stock ECU. But does the stock ECU give you Anti-lag? LOL

Chris.

 

^^^ We are both basically saying the same thing from a performance perspective, the next ste should be engine management. If emisions is an issue, then a piggy-back would be perfect. You can load a "zero" map when you go to get tested, but run a performance map the rest of the time.

I've had my Vishnu Stage one for months now and the performance is amazing. I've just recently started to add more power again.

 

just watch for the po po man...all that money can go into waste...i say just put in an exhaust, downpipe, and reflash...everything else is just too much to deal with..

 

Good points, all. I'll likely end up doing the UTEC for enginge management, though, as TurboXS is more or less down the block. Here's another question: Fuel pump, yay or nay? If I'm running constant 19psi, with intake/turbo back exhaust and a UTEC, does anyone know what sort of difference there'd be with and without a fuel pump in that setup?

And as a side note, wouldn't I want that UTEC there to run the fuel pump in the first place?

 

I would say get the pump, better safe than sorry, and it will be a big sorry if you blow your engine thanks to detonation! But what pump would you go for? Now don’t all say Walboro coz I have heard some bad press about them as of late. There is JUN but I bet that would be expensive and hard to get. I have also seen people with higher power EVO using a Walboro 280 (I think) pump into a swirl pot then a Bosh 044 high pressure pump up to the injectors! Seems to work well but I think it may be a waist unless you want to get really serious!

Thanks Chris.
