The question has been answered, yes a SPI head will work on a 1.9 SEFI block, yes it will lower the compresstion, and it will make it a interferance motor.

I also got a new intercooler, fit's much better behind a stock bumper, with new piping to go with it.

I now have the ability to leave the ignition timing stock and run a bunch of boost. Yes lower compresstion takes power away, but with higher boost and more timing you can come ahead.

Badass Jeff. Totally sweet. So with the lower compression how much boost are you running? What intake mani is that?? Is it justa stock 2.0 mani?

Good work as always.

I will turn up the boost untill:
A) turbo max's out.
B) fuel runs out.
C) get detanation
D) blow's up.

That's just a stock SPI intake mani, it's cleaned up and clear coated to stay nice looking for a while.

Neuman, thats funny you ask about the BOV. I have a spare that I'm gonna polish up and crush so I can vent. It's just way to quite rerouted, maybe I just need to shove more boost through it?

What is that intercooler from? It fits great and is about what I need for my set-up. I'm in the part acquisition stage right now. Currently have manifold, turbo, downpipe, injectors, and fmu. Just a few more items to find.

I guess I'll be going with the 1.9 for now, maybe future improvements though.

Sweet - can't wait to see the results, as long as it's not letter D. :lol:

I think you'll probably hit the detanation barrier before anything else. Probably won't happen till about 10-11psi though. Just need to get that timing pulled there Jeff. I would assume the motor will hold till about 14psi daily if properly tuned. Might not last a horribly long time but long enough. :)


BTW, when you getting some better managment? *hint hint* :wink:

The intercooler is from a 1G Eclipse. Fit's a hell of a lot nicer then my old probe intercooler.

Now that my compressstion ratio is lower, high ignition timing is no longer as much of a issue. As long as I dont go lean I should be fine. So I'll see how far I can take the stock PCM.

how about that lower compression? can you tell a difference when your under boost? how about that timing? as your atourney i would advise you to get a bigger intercooler... now all you need is MS. im telling you dude. even in N/A mode you will feel about a 30% power increase when you go ms and get rid of that shitty stock fuel map. before i couldnt burnout verry well. now ican burnout shifting into 3rd in n/a mode. if i have it WOT at 3psi in 1.9 mode i burnout if i turn the wheel over 5*.you have no idea how much better your car will run with standalone. the fmu/afpr/injector combo is good.. but its crap. dude.. im telling you if your going to turbo do it RIGHT. i will never advise anyone to use an fmu EVER AGAIN.

Hey Jef shouldn't your sig say "1.9 SPI turbo" :D ?
Good point, I forgot about that. :p
screw that just call it frankeisten! i mean what do you have............

1.6L exhaust mani
1.9L bottom end
2.0L top end
2.2L / 2.3L hybrid turbo

thats just ford parts!

I AM SOOOO JEALOUS!!!!! I was going to try to do this next summer if I could get all the parts together. Oh well, that is just a few less $$$ that I will be spending since you made it happen first.

BTW what ever happened to your 2nd gen ZETEC idea, I don't remember hearing much about that project.

Okay, we need an update. When you get this thing moving, let us know. I'm working on my parts for the turbo. I need to know if I need to be getting the spi head and intake. Just how low does it get the compression. I want everything on hand when I start the install.

OK Update:
I've put a few miles on it. What I've noticed is about 10-11psi feels like what 8psi did with high compresstion stock SPI. Any added turbo lag is hardly noticeable, but I really have'nt spent that much time with the new set up. I have no idea what the new compretion ratio is, but I'm sure it's pretty low. The good new's is I'm no longer having to worry about detanation, even with the stock N/A ignition timing. The only problem now is supplying enough fuel and a slipping clutch. When messing with a boost controller I pinned 19psi, went way lean, but I did'nt hear any deto. It was only for a few seconds 1st gear lite up and melted the tires as soon as 4000 RPM's hit and pulled to what felt like 7000 RPM's, surprisenly the 1.9 block likes to rev with the higher flow SPI head. As soon as I hit second the clutch could not hold 19 pounds. I turned it down to 15 and was still lean and clutch still sliped (I had a passenger). So now it's set to 10psi, the clutch is a lot happier, but fuel still can not keep up. I'm supecting FMU problems, I will do a fuel pressure check in the next few day's to find out whats going on.

To build the motor just make sure all the pully's are the round tooth pullys for the timing belt, cam, water pump and crank. Make sure the block is at TDC and cam is set, then install the head. Other wise it will be next to impossible to set since it is now a interferance motor. I used a 2.0 head gasket, but I'm sure a 1.9 will work fine to. I also took the sharp egdes off of the head, to get rid of hot spots.
