For those who doubt, that's why I think I can hit at least 400 HP. This is not a production motor. It is not meant for a production car. It is
a race motor being put into a street car. I am making absolutely NO comprises as far as how I am building this. I also understand that you can't just dump enough money into something and think it'll work if it's not made right to begin with. This is not a 2.3l Ford. This is a 2.6L Super Duty. Remember the DOHC Cosworth Super Duties? Those were naturally aspirated engines cranking out almost 500hp. I will hit at least 400hp, and then some. 
Ported and polished aluminum SD4 head, 2.02" intake 1.78" exhaust valves, 5 angle valve job. Manley Race-Flo valves.
Diamond Racing forged pistons (not pictured are plasma-moly rings), KRP forged 6.0" rods.
Garrett GT35 turbo. On right is my old T3/T4.
I will be using EFI, tuned port style, with an injector per cylinder. I will also use an LS1 throttle body. I had sitting an LT1 TB, but I don't think it's gonna cut it.

18 psi on a T3? That's not a great way to make power... What was your compressor outlet temp? 350 degrees? Get a T3/T4. You'll run way faster on the same boost.

Turn the key and feel the engine shake the whole car with its lope; Plant the gas pedal and feel in your chest neither a shriek nor a wail but a bellowing roar; Lift and be pushed into the harness by compression braking that only comes from the biggest cylinders while listening to music of pops and gurgles. Know that you are driving and American V8. There are finer engines made, but none of them are this cool.Luck, Fate and Destiny are words used by those who lack the courage to define their own future

The 87 - 88 turbo coupes did not have the t3, they had IHI turbos which were good for about 18lbs of boost, they were also intercooled which did bring the temps down. On a ported and polished motor with a 3 inch downpipe they were capable of about 280 hp which is coincidently about what the stock injectors were good for. I had this in an 85 coupe that weighed 2640. With a 3.55 rear gear and a T5 tranny it was good for 14.3 to 14.5 quarter mile times at dragway 42. unfortunately they call them rustangs for a good reason so I now have an 88 fiero for a toy and traded the rustang for a pearl white paint job on the fiero. Eventually it will have a boosted ecotec after the suspension and other things are taken care of.

A GT35 should put your at 400+ to the wheels easily. Especially with a little larger displacement (2.6L), it should be plenty streetable. What is the stroke and redline of that engine? I'm just tyring to get an idea of piston speeds in your engine. Also, the GT35 will stay efficient way up to over 30psi, if you ever want to make one beautiful dyno run. What ECU are you planning on using? That looks like it's gonna be one hell of a motor. Are you makign your own header? Best of luck on your project!

Stroke is 3.100". The limiting factor on the redline are the piston rings. At 10,000 RPM it'll be around 86 fps. I think I'll limit it to 9000, that'll be around where the rings will probably start to flutter. I know of other drag racers using the SCAT crank running higher strokes and regularly hitting 12000rpm. Apparently the SCAT SD cranks have yet to suffer a failure from anything except for oil loss. I'll design my own equal length turbo header, yes, but I'm not going to trust myself to weld it, lol. I'll be using a homebrew MegaSquirt ECU.

Powerlevels and PSI vary from turbo to turbo. SO turbo A could make 300 horse@15psi and turbo B could make 500 horse@15psi on the same motor. The turbo he has is plenty capable of making 400 horse. It will just make it in the neighborhood of 6k rpm.

Here is a Link to his 400HP 2.3 turbo http://www.turboford.org/faq/joe.shtml if you can read you will notice he is running 17 psi of boost with a 90 HP shot of nitrous to achieve that 400 HP. And at this link http://www.merkurencyclopedia.com/Dyno_results/dyno_shootout14.html ther are several dyno sheets from 2.3 turbos running 20+ psi of boost and none of them making 400 HP. As far as ford 2.3 turbo motors having only 11psi of boost I suggest you read up on them a little more. My totally stock 88 turbo coupe motor would hit 14-15 psi of boost and it was making about 200 flywheel horsepower. Turning up the boost to 18 psi took about 2 tenths off my quarter mile time. I don't think turning it up to 20 would have gotten me 400 hp. |

With the N/A DOHC kit on the SD you could choose cams to make 370hp.
