I just wanted to know what has to be done to a Garrett GT28R turbo to make it into a GT28RS and then the RS into a RSr?

I'm just about to order my turbo from ATP and I wanted to know if their RS can be modded into and RSr and how much it might cost?

it costs aboiut £225 to convert an R to RSR... they just install an RS compressor wheel..

converting an RS to and RSR? or it doesnt make much sence too!

Thanks.


But I thought the RSR spools up quicker than the RS. ATP do the RS for about £90 more than the R.
I want to have as little "lag" as possible with the GT28 and thought that I might spend the extra money and get the RS changed to an RSR. Is that not the best way to go about it?

Stick with the RS IMO as long as you have the mods to support the turbo - only a few hundred rpm difference in spool. Depends what you want though I guess....

Remember that the RS comes in different housing sizes - the R and RSR are both 0.64 I believe.

the rsr is nearer the standard turbo for spool up but with far more grunt,the rs has more grunt again,but is more laggy and is more on/off than standard turbo,and far more agressive than the rsr when spooling up. the rs really comes into it`s own above 4500/5000rpm
