First of all id like to wish everybody a merry christmas.
I think ive been sitting about too long these holidays already as my mind has wandered off onto turbo charging the engine for my escort.
Its a 1700 sigma (zetec se) from a puma which comes with all steel internals as standard. What i know about turbos is very limited, i know i need to lower the compression, and route the air from the exit of the turbo to the inlet manifold via an intercooler but thats about it.
*Can i use twin 40 dhla's?
*Can i use a diesel turbo? (I'm not looking for massive amounts of power)
*Can i use ignition only ecu?
This might be a dead duck from the start as i said it was just a daydream i had today

The yamaha engine in the puma is harder and more expensive to turbo than the older zetec engines and makes nowhere near as much power. You'd be better off turning it into a raving puma engine and running throttle bodies for circa 200bhp

The original plan was to run it on twin 40's and megajolt. How come the puma engine is so difficult to turbo?

The compression ratio is 11:1 iirc so needs a fully forged low comp build ideally.

Using a diesel turbo can also be dropped off the list. The diesel turbos have much less heat going through them, in part due to the differing combustion of petrols and diesels, and as such may still not be suited even with a low boost pressure. This has been discussed on the forum many times now  . |

The puma bottom end is actually sintered metal. Basically a powder that's been squashed under high pressure. Great for high revs, pants for boost. The Vvt on the puma lump doesn't lend it's self either. The 1.6 version of the same engine how ever does turbo well. I built one a few years back, pistons and rods, custom exhaust manifold and a t25 turbo. Used the puma metal intake. Made around 200bhp at 10 psi. |

I'm going to spend the next couple of years gathering the parts i need and run the 1.7 on carbs in the meantime. what is the best budget ecu for turbo applications? |

I know feck all about turboing motors so please forgive me if this sounds like dribble but
What about a low blow turbo? Seen them used on chinquicentos ( however its spelt) and a few motorbikes
|

Laser cutting and cnc punching (up to 3mm stainless and ali, up to 6mm mild steel)
Mail me a dxf file and i'll get you a price
Metal folding and custom fabrication service also available

Have seen diesel turbos used on 1.6 Nova engines, they ran fine with a Cometic head gasket and 3.0 FPR.

This has been discussed on the forum many times now . Holsets , Borg Warner and garret diesel blowers work perfectly well in petrol applications . A garret from a 3.0 iveco daily is currently getting beaten to death on a mates mx5 turbo and hasn't melted yet and I've had several holsets glowing without a problem . |

you don't NEED forged internals for a puma engine.
I'm a mk5 fiesta owner with a puma engine, amongst the hundreds of others... lol
turboing the puma engine isnt as hard as people make it out to be.. I'm currently collecting parts for a 2.0 zetec turbo. chose that over the 1.7 as tuning costs a lot more and wont get as much 'bang for your buck' ...
just need the usual bits for a budget turbo build....decomp plate, uprated injectors,remap, intercooler custom exhaust manifold and ideally something like a t2 turbo and whatever pipes are needed etc....
have a browse on projectpuma forum, section dedicated to turboing the 1.7 on there and many many topics about it.
