I like the idea BUT, how are you going to retard the timing under BOOST, you have to pull timing out under a boost condidtion. How do I know, Im running a vortech with 18lbs in my 92 LX coupe car and I have to pull all the timing out under boost, ALL timing, under boost, the plug fires at ZERO degrees, at idle Im sitting at 19 degreee's advance. The VVT-I system advances and retards the timing based on Hydraulics (oil pressure), when you nail it the engine spins up creating more oil pressure thus more timing. The Escort has DDB2 but its a completely different fuel management system. OBD2 is standard but not all manufacturers implement it in the same way. Heres the ODB2 details for any one that cares.

Ctruss hopefully you guys have already done al lyour homework, Id love to see it work.

Adding a 5th injector may solve the fuel problem but then again, putting on larger fuel rails so you have plenty of volume at the rails for the stock injectors may work as well. The stock injectors will probably flow enough fuel for the horse power you are quoting. You dont need gobs of fuel pressure to make power, you need a lot of fuel (VOLUME) readily available whens its needed.
The computer will pull timming. Our xB's have a knock sensor and if it pics up anything close to a knock it will pull timming.

I have dealt with timming issues on the VW 1.8T engines and the ECU is smart enought to deal with timming on its own.

I have good news and bad news on the S/C project.

I am having a super hard time finding time to get into my friends shop to make the mounts, weld up a plenum, and fabricate plumbing for this S/C system so I am going to have to scrap it.

I am however still going to do forced induction......

My friend owns a shop turbocharging cars and my xB is scheduled to go under the knife this Friday.

He is going to fabricate an exhaust manifold, use a T25 turbo, and plumb in an 8x12" Bell intercooler core that is 6" thick. I will be using Celica GTS injectors and an APEXi SAFC II.

I was told the piggyback wouldn't work with our cars, but there is a local tuning shop with a dyno that garuntees me they can make it work with the xB ECU.

Look for my pics on this project soon.

ctruss, I wonder if there is something that tuning shop knows that everyone else does not? It'll be interesting to see if they can actually do it! Good luck!
