Silvertop Zetec to ST170 conversion
Hi guys,
Sorry if this is a repeat topic,
I am currently running a Scholar engined 2ltr silvertop with jenvey throttle boddies in my old TVR Vixen. I'm thinking about upgrading to an
ST170 if it can be done?
Does anyone know/or fitted a T9 grearbox to an ST170 engine?
If it does fit, is it just a case of fitting the bearing again in the back of the crank and what if any change to the flywheel is required?
Thanks
Daza

As far as I know the block should be the same, it's difference is some variable valve timing. I would be more tempted to spend the money on head
and cams for your engine which would give 200 bhp+ easy with the TBs you have. Save the hassle of swapping and more power with less complicated
engine.

As above i'd stick to the standard zetec with tuning goodies (actually i'd fit a bike engine but we wont go there today YET - maybe
later!!).
The variable valve timing will pretty much mean you need to stick with the standard induction, exhaust manifold and ECU as far as i'm aware. Not
heard of any aftermarket ECU's that can be configured to operate this myself.

The variable valve timing can be operated by a simple switched output from the ECU or even a switch on the dash .It is just a hydralic valve with an
on or off action.It could probbably even be left permaently switched on.

Yes - it can be done.
Block is essentially blacktop zetec.

Hi, my mate has just finished an ST170 install into his indy. He bought 2nd hand low mileage engine complete for under a grand, using jenveys and
emerald ECU and is hoping to be pushing 210bhp.

I will ask for some contacts, but I know he was impressed with the emerald set up. I think it has switchable maps. He has rolling road booked for
later this month, so will be interesting to see results.

daza,
Its been awhile since you raised this topic, but I thought I would update on results of the Rolling road. Rev limit was set at 6800, although it could
be increased to 7500 later if needed. It was running a cat!
Power 168bhp at the wheels. I am guessing at 220 at the flywheel. Contact Dave Walker at Emerald, as he set it up. Not bad is it, and for less than
£2500 all in!
