Another Turbo Question

[S13FX]

Hey guys I want to buy this turbo but I can't identify it for the life of me, I know it has a t3 style flange for the manifold, what Im trying to figure out is what kinda flange goes for the down pipe here is the link to the turbo pics

and thats what the sticker says, I tried looking up Rajay but it's like they don't exist anymore. Thank's for you help. This turbo is the only missing link in my project being complete ..

Looks like a T4 turbine to me. T4s often have that round 4 bolt outlet. Also the inlet (pic 108) looks like a T4. Its almost a square while the T3 is more retangular.

Heres the outlet flange you'd need.

And heres a template of the inlet

Good luck with your project. Keep us updated...

Back in the day (1970s-80s), Rajay used to be one of the big-dogs in the turbo world.

My eyes might be bad, but one of your pictures of the turbine shows an a/r of 1.30. That's HUGE! Most people here run .63 a/r T3 turbines on their KAs....

yah it is 1.30 do you think thats too big if Im only going to be running 10psi at first? How bad do you think my lag is going to be?

it looks like the compressor is glued together, what's that all about?

I didnt notice that til Marc pointed it out. 1.30 A/R is HUGE. Ive never heard of someone running that big of a turbo. I have no idea when it would spool up, but it would have major lag. It prolly wont be practical on a KA.
