3500 top end swap would be suggested by most of us. If that isn't enough, then P&P the 3500 stuff before it goes on.

I am having a set of 3400 heads cut for the 1.8/1.52 valves for boosted applications. I will then post flow numbers for the heads and then with the ported manifolds once I am done.

I am very impressed with the ported 3500 top end for its ability to flow at the lifts that matter most. You have to compare the entire system, not just the heads. I will have all of the numbers asap, as well as an article explaining the key differences between the setups.

Ported 3500 parts will be on the store soon 3500 top end swap parts to work on the 3400 engine will be on the store soon as well.

Are you talking about the STS remote mount turbo?
