This R Spec turbo simply has the biggest wheels we could fit in stock location.
TPC has used this combination of wheels any many of our other 2L platforms and have consistently reached 425-500whp with bone stock engines and supporting fuel.
We have faith that the RB community can do the same. We are offering 200$ off for a dyno sheet supplied by customer that meets are requirements of supporting mods.
If you want something that favors more spool we also have a K Spec that has smaller turbine wheel. The K Spec made 432/413 to the wheels on 20psi 94/meth.
