Ok I'm thinking that as far as the engine goes, my next mods will be a ported head from RRM (assuming its reasonably priced), a stage 1 cam from RPW and maybe the phenolic spacers as well. My question is would I need any ECU or fuel upgrades to accomadate this? I'm already considering a cam gear (either RPW or fidanza if they make one) to help deal with some of the idle concerns I've read about but I'm not sure if I could afford to buy all of the above mods and get the car tuned using emanage or something like that. Anybody got some advice on this? Where's alchemist or mitsuman when you need them.

 

Before camshaft you should really look into some breathing mods like ported 4G93 intake manifold and a throttle body. With those two you will not need any mods to make them run like they should. Then you should buy camshaft, cam gear, fuel pressure regulator, ported head, and just throw it in all at the same time. Fuel pressure regulator will assure your fuel supply for now on. If you will have any lean conditions you can always crank it up a little bit. Then get yourself a wideband, emanage, and tune to perfection.

 

I already have a ported intake manifold, and a bored throttle body. Apart from replacing the MAF I have done everything on the intake side of things. I was thinking of getting a wideband next month along with a greddy muffler to make an exhaust cause I sure as hell don't want to blow the engine again.

 

Why do you think you need the exhaust to avoid blowing your engine? If you have bored throttle body, ported intake manifold, and pistons, you should really look into something to keep your air fuel ratio steady before upgrading camshafts. I would safe up the money for Emanage and wideband, both will help you keep things under control, and avoid blowing your engine.

 

I meant the wideband as protection, the exhaust is just to add another mod. Would seem kind of foolish to upgrade the head and camshaft but keep the exhaust tiny.

 

Fidanza cam gears are on ebay. They are like 90 and then 10 for shipping so a good 100 will do.

 

if your running n/a i can't see a reason to concern yourself with fuel. you can put in a fuel regulator but injectors and fuel pump will function to their limits. but i feel there is no need to replace these items. good plugs and wires will be fine.

on another note, be careful with P/P head, make sure rrm knows what mods you have so they can make their adjustments accordingly. i recommend CAI. spacers will give you torque. i think you may net some gains from finishing off your exhaust with a good n/a setup.

otherwise your doin a good job, careful, cams can cause rough idles but i think you've done your homework.

ugh, forgot to mention tune. it's expensive. tuning time is expensive. make sure everything is in before you tune. you'll see gains but have to pay for it.

 

^He shouldn't have any concerns with fuel except without a piggyback and so many mods he might run into few problems.

 

he means maxing out the stock fuel system. you probably wont do it on an NA lancer.

 

You probably won't have to worry about fuel.

 

If you go the cam route, I'd recommend the ecu with it. You'll be changing your valve timing, and air/fuel changes go hand-in-hand.

 

Yeah I'm currently just trying to figure out the best order of things. I might just pick up a wideband first, then greddy emanage or a similar system, then possibly a ported cylinder head and cam. Would seem silly to buy the cylinder head only to take it off a month or so later to install a cam.

 

First, get a dyno! Second, post some numbers

 

Hahaha once I have the money and the time I will. Maybe do a before dyno and an after dyno so people can see what gains are to be had from a cylinder head, camshaft and a proper tune.

 

I would get Emanage first, then if you don't have the money for a wideband go for a dyno. If you will see Air Fuel ratios too rich or too lean on the dyno, just add some fuel. Obviosly the tune won't be anywhere near perfect but at least you will know what's going on, and what to get next.
