Yet another thread about Turboing a 03 lancer.
well today was wierd I had to decrease my lateny by 2% my car has been running rough for the past couple weeks, i think its because the weather change and the engine is cooler
hey 03lance can you help with my wot? everytime I do a pull it goes to bottom 10.0 afrs and I feel it slowing down, it also gradually leans out to 11.3, im not sure what the problem is

headstuds are a good idea, but stick to a Mitsubishi MLS gasket and nothing but that(dont see my receipt, but 80ish$ from dealership, maybe 56.. i donno both numbers sound familiar), they are much more forgiving with boost then decompression gaskets or thicker copper gaskets.
but realistically, Id say just hold off on everything, get some pistons and rods and do it all at once.. If u break or bend a rod, a new motor will set u back about 300, not a big deal, but then u have to get new headstuds and headgasket and start all over. i had tons of parts just sitting at my house just waiting to get installed untill i had all the pieces needed.
If ur never planning on running more then 9psi, then dont worri about building it, u should be fine till the piston rings go bad, headstuds arent even needed.

I might just take the 4g64 out of my galant and build that up nice and swap it in, but not anytime soon, i still need to be pro at tuning before i feel comfortable about upping the boost or anything like that 
Log knock voltage too this might help us with good indication of real knock vs fake knock. I know your not supposed to use voltage alone and I dont without hard evidence to back it up but we migt see a pattern in there somewhere... Also speed and if you feel like airtemp you could throw that in if you wish. I look forward to seeing the results 
Have you tried running or are you running the stock lancer accel enrichment settings? I think this is what really helped me out I had the same issue I would everytime without exception bottom out at 10.0 then it would start to lean out. You can send me your rom if you like I can check out some of your settings

Ya from my experience I think we should leave accel enrich alone I think it causes more problems when trying to adjust it. I played around with it for awhile with no luck. I have read of some evo owners playing with the accel enrich but it was for a specific thing they wanted to do for an event or something and wasnt part of their dd tune.
worked alot better im still having idling issues this latency thing is driving me nuts, 03lance how exactly did you tune to get your idle straighten out? it seems like when I cruise and come to a stop my car goes rich and drops to about 600 rpms and goes up then goes back down while afrs are going from 11.0-12.5 then the O2 sensor kicks in and makes it lean then goes back to stoich...
I wonder if my latency is wrong for my 880cc injectors

Latencys are really tough and tricky to get right. not too long after going turbo I searched online and found stock subie roms and poured over there injector settings and not single one worked for me. But you could try going to the stock latencies and adjusting from there. It was a lot of trial and error and a ton of gas wasted trying to nail those things down. I could give you my latencies although not sure how they would work since you have the altered injectors
Plus....the evos have like, 500cc injectors or something, so when they go to 1200cc, that's slightly over a 2x jump. At that point, sometimes they have idle problems. You've gone from 200 something to 800 something....that's like, almost a 4x jump, which sounds like it's guaranteed to give you idle problems. Even with everything being perfect, you never really know how good those injectors are. Who modified them, and did they ever get "flow tested"?
well I think I came to the conclusion that its not my injectors because they idled fine last couple of weeks, I think my turbo is getting worse and won't spin, because it goes straight rich to 11.5 and the car idles high to compensate for the amount of air. So I think my turbo is officially DONE!!!
so I need to buy a new one.... zulu is probably going to have to wait a couple weeks for anything to move on with the motor buy

Yo steven, have you thought about possibly rebuilding that turbo yourself? It seems like an easy enough task and if you google it, there are a ton of places that will tell you how to dissassemble and reassemble them. Ebay sells rebuild kits, and even performance rebuild kits. I know for the 14b im getting, a performance rebuild kit for it is only about 40 bucks shipped on ebay. You might look into it. Seems like the only thing we need to have done professionally is to have the shaft balanced. Just sayin

im not sure how much the balance would have cost, but if its anything over like 200, prob just worth it to get a new or lightly used one... but this is the approach i took as well, tried to re-build it!
I know if you disassemble it yourself, and bring the shaft to them, alot of quotes were around $40 to have it done, I'm not sure what all they do to balance it. Either way, you could get a performance turbo out of it for less than what you pay to get a new turbo. I also know that your turbo isn't supposed to last as long if you dont get it balanced.

Yeah mine did not last at all after i rebuilt it and never got it balanced
