stock turbo+cams vs. torque limited HTA green?

ah didnt realize that...i would still need a core to send in tho, because i want to keep my stocker around. also keep in mind while your numbers are awesome you probably have 30whp on what i would get due to cams/SD.
thanks for the offer, im on all seasons now, so no more tuning this season unfortunately. without changing parts, i dont see there being too much left, as im already running 104% idc and dont want to go higher.
i just personally dont like pushing turbos to the limit, learned the hard way over the years with various expensive shaft failures pushing t25's to 25+ psi. i dont think i would ever do more than 25psi on a stocker, which will sure make more power, but i have a hard time believing id see 30 more tq, and that being said, the key is i want to HOLD power not just make a number, something the stocker just inherently cant do.

a t25 is a turd though.. i can see 25psi killing a tiny garrett t25.
but something you just said that i wasn't aware of.. 104% idc.. if that's in evoscan its not as high as it claims but its still high enough to be cautious.. in that case id upgrade your injectors first thing.

ya you would need to be in the upper 20's to get the numbers im saying.. around 30psi.

i thank you, but my wallet does not lol. atleast you dont have my exact setup haha. i have a feeling after working a 24hr shift this weekend in a daze im gonna pull the trigger on the green...

boost leak is unlikely imho. i went through everything thoroughly back in the spring, unless im loosing a little out of the injector o rings. the perrin intake really flows A LOT, combined with the mivec map im running and hitting mid to high 260's load, everything looks in order too me.
104% is just the peak ive seen, but like i said, i typically hover around 100% as of 7k, but i havent looked at logs in like two weeks so. im gonna try one last map tomorrow if it gets warm enough, so ill know for sure.

The last time I had a boost leak the one thing that tipped me off to it was that my IDCs were higher than normal at redline. You and I have similar setups, the only difference is that you have Mivec and I don't. I'm not sure how much of a difference that makes but all I know is that my VD numbers are around 365whp/365wtq and I'm running 4-5 more psi than you at 7K but I'm getting the same or lower IDCs.What AFRs are you running at 7K? Maybe you could lean it out a little bit.

last time i ran some logs, i did 361/340 when temps were in the low 40's on a 24psi peak (about half psi more than normal). i run 11.5's in the midrange and push down to 11.2ish above 6800 hence the idc jump.
i keep a road course mentality with the tune and all the plans in general for the car right now. the last thing i want to do is generate more heat than i need to.

so to do some guessing...with a ported megan o2 housing and say 25psi, would a 15whp gain be a safe guess?
in driving around today in beautiful weather, the car was moving almost fast enough that u could surely get in a lot of trouble lol.
still no idea what to do...

look at how much each mod will cost and weigh the pros and cons from there. either way you're going to want to have the car re-tuned to maximize the effects of both cams and the green. you can rebuild the stock turbo for relatively cheap. I took a stock turbo and rebuilt it a little more durable and ran 28psi through it with no problems, but I also had 272 cams and other mods to help. just keep in mind what will have to be done after you do each mod to keep the car good for everyday driving.

i do all my own tuning after i had a tuner blow up one of my old hondas on the dyno and after lots of arguing admit it was his fault...i just have an inherent distrust of tuners now...cuts some cost too.
i plan my modding around work vacations (or maybe vacations around modding? lol), the car will come out of storage in march, at which point i will probably put in fuel pump and injectors to get them dialed in and so i can do some suspension bits to be ready for track day season, and then my next vacation in june do a turbo swap.
