155s vs 175s

[94slowbra]

so what the difference, benefits and downside to each? i know the 175s will flow more but at what expense? i was contemplating 155s till i talked to warren diesel today and he said the 175s would not be too much for me. due to budget restraints right now ill be sticking with my stock turbo for the next few months and then upgrading to a MTW stage 1 with new billet wheel. truck is a daily driver and am looking for reliability, fuel efficiency, power and towing capability. i have toys that make big power so im not trying to push this truck to the limit. truck will be tuned for injectors once installed. are 175s too much for me or am i going to kick myself by going 155s down the road? thanks

175s do it you won't be sorry

agreed 175's!!!! now was this stock nozzles im assuming?? honestly i dont like 155's because i feel like you spend the money for such a small gain. kinda like when the powermax came out. someone would spend 1200 bucks for such a minimal gain that it wasnt worth it. but thats just my take on it

I love my 175/75%

But I think they will be too much for you with only a stage 1... I mean to fully clean them up, run cool while towing (I remember you saying you tow quite a bit), and not smoke everyone out LOL

For your system, I would recommend some 175/stock nozzles
Maybe 30% if you wanted to

So it looks like a 175 stock nozzle is in my future. Will a stock turbo clean these up ok with the right tuning?

Questionable, will you be able to make smoke, oh yeah. can you drive it smoke free almost.

It will come down to tuning and how much fuel your tuner can take out of it and still have some HP n Tq. gains.

I'm eagerly awaiting the new wheel for my Hybrid because the Stg. 1 wasn't near enough to clear up my 175/75's

175 / 35 would be the max i would run with a stage 1 or hybrid but it depends also on how much time you spend boosted 20 PSI + and above 2K RPM's. Where MOST 05's can't go. I no mine can't :-(

I don't have my setup tuned to perfection yet but I am glad I went with 175's,the smoke isn't bad and I feel like I have plenty of fuel on tap once I get the air dialed in.

Havin had both 155's and 175's in my truck with the same turbo I can say I like the 175's much better. The power increase is night and day. Like mentioned your not getting much bang for your buck with 155's.

[94slowbra]

Well i have been given permission by the wife to upgrade my turbo to the stage 1 with billet wheel when i do the rest of the upgrades. I think my 175s will go perfect with this turbo

Just FYI I have the Stage 1 with Billet wheel and it cleans up a full fuel race tune on my 175's at WOT.
