Hiya all, quite new to the site, i dont post much mainly browse through threads, apologies if this is in the wrong section too.
Ive decided (a year ago) to build a 2.1 zetec turbo lump to drop into my 'sunday' car. Puma.
Ive built engine before but on a larger scale (Agricultural) so fancied having a go at an engine build myself.
Ive started to remove old engine and collected the main of the parts: block - 2.0 black top
head - ST170
rods - eagle
pistions - cp (through ian howell)
clutch - AP
gasket sets ARP bolts etc.
Had the block bored and the botom ed balanced so far.
Will be starting to rebuild in the coming weeks.
Few questions,
Do i need a different sump to the standard 2.0 one i will have, for routing the exhaust?
What manifolds should i be looking out for?
Wanting around 250hp but i want reliable power with the option of uping the power if needed in the future.
other than replacing the obvious pumps etc, any thing else i should consider?
Oil feed for turbo, Use pressure switch port?
Regards, Matt

Use the 2.0l blacktop sump setup, for the power your wanting a escort rs manifold and a stage 3 turbo should be fine, you could use a manifold adapter or re drill the head, then use a escort front pipe to mate to the puma exhaust.
Use a erst oil feed, and the take off where the oil pressure switch goes, 3 bungs on the back of the blacktop engine.
ST170 valve springs.
Not sure which inlet will fit in a puma bay.
You will also need a decent clutch.
You need to decide on a management set up and if your gonna incorporate a sports cat to the system for MOT time.

Thanks for the replies so far.
Using the ST170 head for flow reasons and it was available cheap.
Whats the difference with the Escort manifold, is the stud pattern completely different or thread sizes?
If Focus RS parts are a straight fit and widely available that may be a better option.
Havnt thought about management yet, MSD arent too far away from me so may use them.

The Escort rs turbo manifold has a different flange and bolt location compared to the zetec exhaust manifold.You can buy adaptors for the escort manifold to fit to the zetec engine though.It all depends on budget as well.

May look into RS manifolds i think.
Can anyone shed some light on the 'high pressure oil supply?'
Heard it mentioned a couple of times now.
Stripped and cleaned my oil pump this week. Is it worth upgrading the gears or will standard ones do? Ive spent a fair bit on uprated parts so far, i dont want the chance of an oil pump wrecking them! pistons, rods, bearings etc.

only issue with zetecs appears to be crank nose walk, or something technical like that.
it seems under high rpm and stress that the crank flexs at the end, which is fine to a degree, but where it drives the oil pump it causes issues, hence so many going dry sump and not having any problems in that area.
i did run circa 400bhp+ with a standard blacktop pump on standard bottom pulleys and didn't have a failure. i simply stripped it, gave it a good inspection and clean, rebuilt it to torque'd specs etc. and it was fine for the few thousand miles i ran it for bouncing off the 7400rpm limiter quite a lot, was using a gt3071r 0.63 at 1.8-2.0 BAR most of the time.

Seen a few that have been turbo'd with no problem. AystenW has a high power one with no problems as does Will Pedley. I have been told that a poor porting job can lead to a warp but surely the net would be full of threads if it was an issue?

Thanks for the replies. Some useful info there. Stripped the standard oil pump it seems fine but after putting a fair chunk I will get a new pump for piece of mind.
Is the mk1 focus oil pump an uprated version or same as 2.0 zetec item?

Had a few hours on the car this weekend thinking about problems!
PAS pump and alternator are 'switched' compared with the original setup, is there any variant of the black top zetec which has the alternator on the front of the engine and the PAS pump on the rear?
May have to buy some brackets or modify the wiring and steering pipes.
On the plus side the AC will fit straight on!!

To all turbo builders:
Is it recommended to uprate valve springs in a black top head?
Will standard cams be suitable for 250-300hp or is it worth investing in a set of turbo cams?

Looks really good, what fuel pump do people use with zetec turbos? Bosch 044?
