Hey I found a guy that is selling an rx7 turbo with no shaft play or problems for $50 but I want to know if it's an s5 turbo rx7... Please let me know guys

 

If I remember correctly they both have the same code, ht18s-2s the only difference is the size of the internal waste gate, which is vastly larger on the s5. Hope that helps

 

pics!

 

Damm I need to find out an Ima tell him to send me pics of it

 

s5 is easily ID,, the front compressor hard line for the wastegate signal has a Tee built into it
the wastegate arm has a bend in it
the rear cover plate on the turbo is much larger, under there is dual wastegate flap doors
the s5 turbine volute is more rounded,, s4 is flat along the tops

 

There you go guys is it s4 or s5

 

s4

 

yep, s4

 

Dammit I wanted an s5 so I can send that one to BNR and use it on my s5 tII

 

the rear turbine housing swaps readily
( unless the s4 turbo is a very early one with smaller banjo fitting and a double heat shield on the hot side )

 

Ok thanks guys!!!
