How good are the SPA turbos. I'm sure the manifolds are good because its kinda hard to mess that up. Are they made by garret or something, or are they there own brand.Why the t28 ? Go with a t3S60 or something close and get better results and SPA makes a cast manifold for that and they have turbos to fit it
Yeah, and one of the first things they do in the UK is get rid of it for a better flowing manifold... usually one made by Goode. Thats why you see them on Ebay, everyone is trying to unload them.I get a good chuckle when conversation turns to the RS log manifold. In the UK, they get up to 300 at the flywheel with it. For a Zetec without a built lower end, there is more than enough power from the manifold.
Yes it is cast. Fits a nice clean stockheat shield. Works fine with GT25/28R. And no,
you won't be seeing 300 whp with one. Beyond the one limitation, there's a good little turbo manifold.
Now right about know the power guys step up to the plate and say why limit yourself?
Well, maybe I'm using a stock low end. Maybe 220/220 at the wheels will be enough for my daily driver. Maybe I'll never have the money for forged rods and pistons.
It is my opinion the RS log is a good manifold. It is not a big hp design. Not everyone wants big numbers. Maybe, we just want boost, turbo boost. Enough not to break the only engine I/we happen to have.
Wrong. Bud, you're looking at a pricey car being the Focus RS over there. Those folks who want to upgrade pay on the order of $700USD and up for a replacement. They don't bother with cheaper weld up log manifolds either. And don't forget about the less well off guys over there who are buying up these "unloaded" RS parts to upgrade their non FI rides to boost.Yeah, and one of the first things they do in the UK is get rid of it for a better flowing manifold... usually one made by Goode.
