reworked turbo

[Captain KRM P5]

The description on the website doesn't mention wastegate work. I saw in another thread that the wastegate's limited flow is one of the reasons that modded MS3s have such a problem with spiking, but it can be helped by a little work on the wastegate. Is there any improvement in this area on these turbos or do you not agree with that estimate?

you can port the wastegate to help stabilize boost control, which for most of these we do not do. we don't see or hear of a large amount of these units spiking radically so its not a concern we addresses honestly. its a far bigger problem with the GT / garrett turbos

How about those bigger turbos offered, are they already made to fit our cars, or will some modification be needed?

the GT series we get through ATP has its own set of quirks and challenges. that and cost is one of the bigger reasons why people go with our rework. those will bolt to the downpipe and manifold, but keep in mind these flow alot more volume per psi and tuning is recommended. boost control has been difficult for some people on these as well due to how they have the wastegate setup.
