Turbo Charged Crossflow

[revingtosh]

Hi everyone - before you all pile in - i know what you are gonna say... "Why not just fit a Pinto / Zetec / Whatever..."

In the interests of building something different,  not to mention cheap - has anyone got any knowledge of Turbo Charging the 1300 xflow?

Im thinking that id like to give it a go as an interesting engineering exercise - plus my 1300 motor has only got about 70000 miles on it,  so its a nice starting point.  

I dont want to throw money at the problem - id like to get as many second hand parts from scrapyards / ebay as possible - just to build something different.

Any constructive thoughts & opinions would be greatly appreciated.   As would any suggestions on Turbo / Carb/ Management etc.

Cheers

 

Mike

I'd suggest using the Solex carb from a Renault 5 Turbo, I think they may have been used in Xflow Turbo applications before...

 

There was a lot of info and examples (x, x) of Xflow Turbo's on Turbosport, probably makes a good read if you're considering it.

I like the sound of that . Could be a easy job to . I think but may be wrong the bore is the same on 1100 1300 1600 . I know if you put 1100 Pistons in a 1300 you higher the compression . So ?????? If you put 1600 in a 1300 may be you can lower the compression . Just a thought and might be completely wrong . As said Renault turbo carb would make sense and a escort rs turbo are plenty full and sized for a 1600 so not worlds apart . They have a a/r of 42 cold 38 hot from memory . Just a manifold to make . Just rembered that mini metro 1300 had turbos to . Perfect size for you .

Good luck and pics a must .

I would use a Metro Turbo SU carb as it would be well suited from scratch

What sort of Torque and Horsepower would be reliably achievable would you say?

I want flames and bangs from a side exit exhaust by the way.  Thats mandatory

1600 rs turbo is 130 bhp so some where between 100 bhp and 130 bhp but more torque

S you can see fitting 1600 pistons will only get the 1300 to the same compression ratio as a 1300 LC

Still 8 -1 is ok for Turbo application

Just the Solex EEIT carb from the Cortina will do and is the one Ford used on their Capri Turbo cars.

 

I even have Ford documentation  from the early seventies of Dagenham projects using a stock Weber DGAV or DGAS carb.

 

As long as the float chamber ventilation, vents inside the airbox any carb will work. So float chamber and throttles have even pressure. Fuel pressure needs to be raised equally with boost pressure.

 

What do I know, did build my own carb'd turbo project and running it for years. Fuelpump and boost referenced fuel pressure regulator is the key.

 

Ignition timing can be retarded using a Boost Timing Master as you need about 2' retard / psi of boost.

Under just driving conditions you hardly see any boost so you can run the same advance as you have now.

 

9:1cr works fine with 7psi boost. Running 9.4:1cr with 10psi boost myself.

Ford used 9:1cr with their 2.8 Capri Turbo's and 7psi boost without intercooler.

 

Did think about a second project involving the same engine to. Have a '83 fezzy with a low mileage 950cc Kent engine in it. Engine is to good to swap but the about 40 bhp aint satisfying. Lack of time prevented me to start the project my self so far....

My cheap list involved,

El cheapo Bosch knock off injection pump

Malpassi rising rate fuel pressure regulator ( the one Burton sells as 2.8Injection to carb conversion regulator).

MSD Boost timing master.

El Cheapo China small turbo to work with my small engine.

Some flanges and a external waste gate setup.

 

Horsepower rule of thumb in blown applications ( just normal boost levels ) is about 50% increasement over stock.
