1) I searched and can't find the max power the stock SPI can handle internally?

2) I would like to know how many people are running stock boosted SPI's and what they are running. I use my SPI as a daily driver but once in a while I like to go to the track, so reliability is before power.

3) How do you escort owners keep your car from knocking, spark knock? Any suggestions to solve this for a budget build. I've read FMU/FPR work for fuel but I'm curious how you tune the spark.

Well depends on the tune, bad tune (fmu) would be low hp, Good tune ms or a piggy back, More hp

I dont think we really know a Carved-in-Stone hp number.
We normally have tranny and clutch issues before we have rod & piston issues.
But with a good tune and the right turbo, you might beable to make 250hp and 300ftlbs if you do every thing right.


There's not too many people that do it right, very few run a stand alone or get a ECU flasher.

What year is your escort?

I have a 1998 SE 5sp. I have a guy around here that can flash SCT but I was hoping that I could drive a while before I dyno tune it. It's hard to get an appointment and he charges a lot.

I have a 14b from my brothers civic. He also has 450cc's from a talon and my other brother has 500cc's from his prelude, fuel injectors. But these are peak and hold how would I get them to work? How much power would you suggest I shoot for? I have a new stage 1 exedy clutch going in also but everything else is stock.

what was NYInTheBuilding pushing in his SPI block, 300hp? its doable - just get the right parts and a good stand-alone - check his build in the sticky in this section.

NYInTheBuilding has the SCT Pro Racer package which I can't afford. The turbo I have is set at 7-8psi from factory. From what I understand there is no way I can drive the car without being tuned with that much boost. What do you guys think about supercharging? I saw it in the sticky and I has an Eaton M62 laying around in my garage.

Its the same thing basicly. Turbo or supercharger is going to force more air into the engine so therefore you have to have it tune either way. But if you see the very few people that have went the supercharger route ended up going turbo seeing that they could make more power that way. The choice is up to you.

Did he find his dyno sheet that he lost?

Since you have a 98 you cant run a FMU. But you can use a 5th injector.
What's the higest octane in your area? Is there e85?

You can run resisters on the low impedace injectors to keep your ECU happy.

The highest octane I have is 93. Nope, no E85. How do I wire the resistor box in. I wish there were more how to's like on the civic forums.

Too bad you dont have e85, dok33 was running 12psi to a stock SPI with stock timing, with no deto.

You wire the resisters is series to the injectors. But what are you gonna use to tune in the bigger squirters?

not sure exactly how much in common the zetec and spi have (ive seen sohc conversions in links from jeff in the past etc) but for the focus guys 250-300whp seems to be when the engines fall apart regardless of tune. some last longer than others, but either way you are on borrowed time. the con rods are made for an engine that can rev easily in n/a form and get good efficiency so they are light weight and not overbuilt like a factory rod in a bp. they are designed to safely handle 100whp for 300,000kms. Keep that in mind when searching for the limits.

You mean kinda like the Mazda 2.0 FS motor? :whistle:

Well I'm sure the 2.0 can hold more, but I made 155whp/190wtq on 1.9 with a slipping clutch and shitty tune at 10psi. I later replaced the clutch and got the tune better. Was trapping 95mph in the 1/4 at 10psi. Got it to run 17psi with meth injection and 93, anything over that would start to ping. Never dynoed or dragged at that level but I'm sure it was over 200whp. Engine is still running great today (in another car) and had unkown mileage. The engine I replaced had probably over 200k with 30-40k of it being boosted. I replaced it because I thought I was getting lots of blowby with the rings but a few months later my turbo blew so I suspect it was from the turbo and not the motor.

With an FMU and meth inj. I ran 9-10psi on 93 with no problems. There were a few times where I messed up the boost controller and ran 14-15psi and didn't get any knock, but I was running the stock fuel pump at the time and it would max out the fuel and fall on it's face after 4000rpm

i actually have a book called "how to tune and modify engine management systems" and they have an entire chapter on their zetec focus project car. They blew all 4 rods at once racing a z06 at over 150mph at 9psi with all supporing mods and a big t3/t4. They talked with people from fords racing program and there are all sorts of good bits of information in the chapter. maybe i fi can get my hands on a scanner Ill post it up. They stopped at 350whp without the nitrous turned on and were spanking z06s no problem at the drags once they built the motor. Most interesting part of the chapter I thought was when a ford racing engineer pointed out that with excellent balance and no lightening, the stock zetec crank is good to well over 8000rpm without any issue and the factory ignition can handle 10,000rpm with high boost.

wow.
