hx35(w) vs hx40 vs s300
 

well guys my turbo is starting to make tinkering noises like its on its way out. according to the mods in my sig which is about all i will be doing power wise, which is the better or the turbos i can upgrade to. i really dont want to spend 1000 bucks on a turbo if i dont have to. what turbo and what size should i go after and the truck will be a 5 speed.

is it worth paying the 1000 bucks for an s300 or is a used hx40 a good route as well? and since its in a chevy, i dont have firewall clearance like the dodges do, so i need the exhaust housing not to be super long so it doesnt hit my firewall. any ideas?

Here is a good little read for deciding what turbo will fit your HP needs. As far as affordability, I don't know what to say. It sounds like you need a turbo asap. I've seen some awesome deals on craigslist for used turbos lately. If you could hold out at all and save up for an S300, I would. Good luck, pickin.
Selecting the best turbo for your application is a matter of choosing the right turbo for your intended power level and your intended

i think im leaning toward the hx40 due to the price. what size should i look for as for exhuast ports and whatnot. im thinking the 14 cm should be fine. but how about compressor wheel size and whatnot.

and also for an hx40 does the downpipe go straight down? or will it hit my firewall

I didnt have a cast elbow on my super hx 40 just so you know... I had to do some fab work but I made it a 4 inch down pipe. im sure you could do it better than mine but I was stuck with a 45* bend and some flexpipe to make mine work. and even then it was tight fitting

You can buy regular S300's rather inexpensively.
They just won't say HTT or the like on them.

and where would i find one of those?

and im not too worried about making a downpipe thats all easy stuff for me

I have a link on a diff computer I will look when I get with it.
Actually for a downpipe you may want to see if you can find a 1st gen Dodge truck downpipe.
They have a very sharp bend right off of the turbo.

not to make fun but thats why i ditched my stock down pipe, i think it would be a better idea to fab one up then put that kinked thing on. and from what i have heard the HX40s have weak shafts that tend to break under certin conditions, correct me if i'm wrong. I'm saving up for an s300 just seems to be a better turbo all around(and i have plans for twins one day and s300's make for a good upper turbo)

i would love to get an s300, i just cant afford to spend that much on a turbo right now thats why im leaning towards the hx40. and i know the sharp bend in the downpipe sucks but i think BTI was referring to when i said i have VERY limited room for firewall space and he is right. i dont have anywhere close to enough room to run a bigger downpipe.

as for the hx40 being a little weaker, they are also very easy to rebuild from what it looks like. is that true?

A regular HX40 has the same shaft as an HX35. They are by no means "weak." Have you ever heard of a 1st Gen breaking an HX40's shaft? Nope, me neither. The people who break shafts on HX40's are the 500rwhp P-Pump pulling trucks who have absolutely no buisness running one.

You have nothing to worry about running an HX40 on a 1st Gen. That being said, they also make "Super HX40's" which have stronger shafts, a 7 blade wheel and move more air than a standard HX40.
