So i found my rs manifold that i purchased awhile ago [woot] and i heard that it can fit on the spi engine with small mods...now my question is what are the small mods and what turbo do they use?

If it's from a Escort RS 1.6 turbo, then you wont have to mod the flange at all, it will bolt right up. But the SPI uses "D" shaped exhaust ports, while the old 1.6 has "o" shaped ports. Should'nt cause a problem, but it might have a gasket leak.

It should fit the Foci engine bay well, there's no front engine mount or PCV block hole to get in the way like there is on the Escort SPI. You'll need a custom down pipe, and I think thats it, just the normal turbo stuff.

A small T3 will get close enough to the fans that it WILL melt the the plastics and the wires. A cheap, slim fan from Summit or Jegs will remedy that no problem.

Get a front mount fan, and stay away from the *********** meow ebay turbo's, I know there super shiney and cheap, but get a real Garrett T3.

that flange kinda looks like a t2 (t25/t28) its smaller then t3 and a t25 would probably be perfect on an spi.

Yes a china ebay BOV should be fine, I've been running one for around 30,000 miles.


Just save your self some trouble and get a turbo with a internal wastegate.


A store or person that sell's them.
I though internal wastegates were more prohibitive and actually more difficult to perform maintenence on?

There's really no maintenence to be done on a internal gate, the only thing that can go bad is the diaphram in the actuator, but that can be replaced.

terrible idea. You need more fuel under boost, not while idleing or under vac.

The MAF wont be seeing "pressure", it will be seeing air flow. You'll put the maf on the inlet side of the turbo. Yes you'll need a different MAF, the stocker will max out quick.

If you can find a T25 off of a Nissan SR20DET (Red Top) it would provide you some boost, and not too much boost that it would harm your engine
