ooh looks like I managed to get it right for a change !
May 98 Silvertop for 90 quid with <70k on the clock.

Thats the best option, bit of head work and some cams can = 200bhp.

Ok,
So a swap to the ST engine will yield ~ 35 BHP without any headwork or cams?

You will need a way to control the VVT.

Reading various posts on this topic ...
Option 1 is the replacement kit ... need a certain level of mechanical skills which i don't have.
Option 2 is the switch in at defined rev level ... I can work this one.
I also have the Megajolt system so option 2 is the easiest way.
This should still give the 35 odd BHP increase - with option to fit a kit at later date.
Is this a correct assumption?

You missed the best option of using the oem ecu

Cost too much ....
looking for best option to get more power as cheap as possible.
From what i can see, its a straight swap for the ST170 and when funds are available get the head done.

the problem with the ST170 is you need to deal with the VVT system 
what ECU are you planning to use ?

I suspect if Big Wasa can work his magic it may be the cheapest option for 170 horses and a big dollop of torque. You would probably have to use the
OEM manifold though which is a bit of a lump. Having said that I don't think the delete kits are too expensive and you could probably give a
locoster a few quid to fit it- the delete kit seems to get good reports when done.

Didn't I read somewhere that fitting (2) two exhaust cams into a 2 litre black top gave a useful increase in power.....

Current setup is Blacktop 2Ltr Zetec with BoggBros manifold and R1 bike carbs.
With the Megajolt system I can program a switch for say 3000 RPM.
My non technical logic says the ST170 engine swap would give increased power (upto 170?) and more grunt torque over the current setup.
At a later date, other options to improve the Zetec (Duratec ST170) could be reviewed to get around 200BHP.

Now this is where i get confused - easily done ...
How does the Blacktop go from ~135 bhp to 160 BHP.
Does this mean the ST170 BHP will become ~ 200BHP.

^^ the short answer is 'No'
would you plan to run the ST170 motor on your current carbs ?
I doubt it would give you the 170 in that case - at least not with out a bit of work
also if you keep the same carb's you've got now they aren't going to be able to give you much more power than the bike they came
from - so you may need bigger ones if your looking for big power (but this could cost you some low rev drivability)
a carb'd R1 is rated at 150 bhp, bogg bros told me they reconned they are good for ~160bhp+, but to go much beyond that you'd need
bigger....
the engine is only going to give as much power as its weakest link can give
the std. ford 2.0 blacktop is found in family cars - so ultimate performance in not the priority
so by fitting some less restrictive intakes (i.e. carb's from a superbike that %100 about performance)
a less restrictive exhaust and some lumpy cams you can get a big power boost
but it'll cost you fuel economy and refinement
but the ST170 engine is trying to be two engines at once:
one uses a mild cam setting and is tuned for quietly running down to the shops
the other uses more aggressive cam timing and mapping to give you some extra performance
it changes over between the two if you drive/rev it hard (can't remember what the actual trigger is on the ST170)
the ST170 is meant to have a few other upgrades like a better ports in the head etc... which are worth a few BHP over the std. 2.0
and using a VCT delete kit lets you manually fix the cam positions at whatever timing suits you best (i.e. simplifies the whole setup)

2.0 Litre Zetec Blacktop tweaks
You have to remember that these BHP figures are usually Flywheel BHP, the wheel BHP is usually 15-20% less.
The zetec 2.0 does state 135bhp, so to get a reasonable increase Throttle Bodies are the cheapest option for the biggest
gains. I have Hayabusa TB's with an OMEX 600 ECU on my 2.0 blacktop and now have 168BHP (Flywheel).
I'm now going for a Stage 3 head with some race cams and a decat so should expect to see 210BHP. Reason I know this is that
the centre doing the work have just done the same on another zetec.

My St170 gave 166bhp with bike carbs (badly out of tune btw). Then I moved over to injection using GSXR TB's on the front plastic ST manifold.
That gave 178..
My next upgrade was to junk all that, go back to a 2L Silvertop and slap a turbo on it for 350bhp...

Nice one Coozer ...
so a simple engine swap from my current 135 BHP setup should yield ~ 170BHP without the need for throttle bodies and expensive CPU.
I Like it
