ok everybody. i have 3 posable turbos for a set of twins. the top turbo will eather be a hx40w or a hx52. and for the bottom i am looking at a s475, holset ht3b, or a garrett t88. if im not mistakin they are all around 75mm Compressor wheel. really need some imput on this.thanks

 

hx 52 as a top turbo is going to be a very slow spooling set or twins.

 

i was thanking that. im thanking the hx40 and t88 or ht3b

 

i hx40 and s475 would be sweet to.

 

Yea true. Thanks alot man

 

A 40 is fairly slow spooling and it will spool around 200 rpm's slower in twins. On a manual trans it's easier to handle but I had a 40 as a single on a tight convertor and didn't like it at all. I've had a b1,hx35,he351 and a 341 over 3b's and 475. I like the 341 on a lower horsepower setup,it spools really fast. The rest are around 100 to 150 rpm later spooling.
I'm cheap so 3b's are what I've been using,again a decent turbo for 5 to 600 horse setups. The setup being put together for my 95 is a he351 over a ht60.

 

i had a hx40 on my 01 for a couple of months,it spooled way too slow for my tastes.the hx35/40 hybrid i'm running for now is much,much faster.

 

Well im running a hk52 single right now and I spool it with very little trouble. But thanks for tje ininut
