after I put Mach 4's and a dd clutch in I will be looking to upgrade the turbo. I would like to end up with a good set of twins. I need them to be daily driven and still be able to tow. The thing is, is I will only be able to buy one at a time with a good bit of wait time in between them. So what would be a good turbo to run with my stocker until I can get an other one and what should the other one be?

oh and I will hook to a sled

What do you mean "run with my stocker"?

Usually when people are buying are charger with twins in mind, they'll buy their top charger and then get a 2/3 twin kit from somewhere to finish it off.

A cheap top charger would be and HX40 with a 14 or 16 cm housing. You can also get a S300 variant to run as a top charger.

I was thinking of buying one turbo now to run with my hx35 in a twin setup until I can afford an other turbo to replace my hx35 unless there is a good combo of twins that uses the hx35. Or should I buy a single to replace the hx35 then later make it(?) into a twin?

Mike D

So I guess you have all the piping and everything else to put twins together?

Flatbed24v

no but that stuff will be easy for me to get and do. I just need help picking out what turbos to run, so if you can please help or suggest a set of twins that I can run. Which one to get first and can I run it with my hx35 or should I run it as a single. I would like twins as soon as I can and since I can't afford two at one time I was wondering if I can make twins using my hx35 until I can buy the second turbo

get a s400 to put underneath your hx35.

after you out grow that get a 62 and put it on top of the s400

Flatbed24v

thank you dieselfan that is the info I am looking for. What size is a s400?

Mike D

The reason I asked is because not all top chargers are going to use the same hotpipe..... Example, the hotpipe to run a 35 on top will be different than a S300 like dieselfan suggested.

But anyway.....

Flatbed24v

I don't mind having to buy the hot pipe twice to make it work

Flatbed24v

mike D what would you suggest then

dieselfan

here are some s400 the 75mm with 1.32 ar is the most popular, lots are switching to a 80mm now

thanks for the link great stuff. I am still trying to learn turbos, what does A/R effect if you increase/decrease it. I am pretty sure my hx35 is 56mm but what is it's A/R so I can compare it to the s400

dieselfan

hx 35 is 12cm, i think.

.90 ar will spool fast but pull less on top, 1.32 is bigger will be slower to spool, but pull harder on top.

thanks that helps me understand a little more
