Zetec turbo conversion
Hi all,
Long storey short, due to the change of Rops regulations this year I've decided I'm not going to sprint the car, so I can build the engine
how I want. I quite like the idea of a turbocharged engine, I'm more or less settled on an exhaust manifold ( boost performance ) the turbo
will either be a disco potato or a holset hx30 . My main problem is that the engine is running jenvey throttle bodies which I would like to keep, I
know that jenvey make a plenum for them but at quite a cost. I'm pretty sure people have used a pulsar plenum in the past on a zetec but
I'm not 100% if it was with the throttle bodies, if any of you guys can point me the right way, it would be appreciated.
Regards
Shooter

If you can stretch to the cost of a jenvey plenum then thats the way to go, throttle bodies do give slightly better throttle response over a common
plenum even with a turbo.
What engine management are you using?
If you keep the TBs you will need the ability to run hybrid / mixed mode fuelling. Alpha N (TPS) with speed density (MAP) on top.
If you switch just to a common plenum with a big single TB then just run speed density.
We have done both of the above in the past.

That's for the reply, dropping the thick end of a grand on a jenvey plenum sort of makes me shudder, especially as I've seen pictures of
them blowing out after a back fire, hence hoping to use the pulsar plenum.
The car uses an emerald ecu, so I think I should be ok.

Just as an update, I've just picked up a complete plenum off a pulsar today, the runner stubs look fairly close to jenvey set up, when I get
time I'll get a decent measuring stick out and have a good look. The idea at the moment is to mill the stubs off flush weld a plate on the
bottom with the correct spacings/stud holes and blend in where necessary.
