Morning. My s2 running 1.6 cvh on mfi is needing a new block at least if I had a budget of say 1000 - 1500 what options would I have for engine swap? What parts would I need? And what to do about management?

Thanks

Lots of questions there.

1500 will get a bottom end with rods and pistons but not fitting and maybe some costs while buulding.

management system is around 1200 for something worthy.

Cheers Janno but I'm going to do the work myself as I'm on a tight budget for now just after a reliable 200-250 bhp.

Looking at a silvertop conversion but need some help what power do the standard rods/pistons take and how do you go about lowering the compression ratio?

Does anyone have a link to a fitting guide?

Also does anyone know what management to run as I'm a complete novice with it but wanting to learn thanks

Better + cheaper option would be an ST170 bottom end with a Blacktop head, bottom end has supposedly been proving at 350bhp so plenty of strong enough for a moderate build.

Mines done 293bhp at the flywheel on a st170 bottom end, only mod to bottom end is ARP conrod bolts.

It still isn't a mega cheap option even if you can do it all yourself, a lot of little costs here and there soon add up, things like suitable clutch, all the gaskets and seals, I reckon my engine still stood me at a grand, I did use a brand new head.

Then the op needs management and mapping. Deffo worth him having a look through Karlos's guide though.

Ideal thanks for the replies looks like this is the route I will take.

What can I do about management as the car is currently on mfi. Is the fiesta efi conversion suitable or will I need to go aftermarket

Thanks

OFAB/OFAC I think would be your easiest option, not so easy to come across these days though.

Joycey85

would that be the fiesta management?

studabear

aftermarket would be my choice.

Joycey85

It's all to do with cost and my limited electronic skills mate or I would

studabear

You have to think about the things like aftermarket will have a new loom, new modern ecu, more features and a much bigger selection of mappers compared to the old fiesta ofac/ofab. Unless anybody does a decent off the shelf chip for a zetec turbo??

Joycey85

I see what you mean so is megasquirt a decent system? Going for a decent rebuilt efi cvh now as it's keeping the car a little more original

CrOwSoN15

Plenty of MS mappers around, good DIY too.

Joycey85

Going for the ms 2 as it's within my budget can anyone tell me wich one to get as there seems to be different ones I will be running an efi cvh.

thanks

Have a look at boost monkeys site, they do a proper built ecu with a better connecter for the loom.

Joycey85

Just looked there I see they have a proper conversion kit coming soon so I have emailed them to ask for details and dates could make my life a whole lot easier
