After searching an getting a lot of people telling me one thing and other saying other things i decided id register say hello and hope someone can clear things up..

i don't have a huge pot of money so i want to get it right

I currently have a 1.8 silver top zetec running 40 webbers i have bought a New 2L blacktop engine to replace it

i need to know what changes to make not "i think" i need to know the fact's ill mention the ones im aware of and were go from there ....

1) I know that the sump is a 2 piece sump on the black top and will need shortening.
Or i am told my silver-top short sump will fit with sum light modification ... What is the best option ? shorten blacktop or modifie the silver-top one .. (Please not i cant afford to splash hundreds on a shortened blacktop one from dunnel or raceline )

2) i need a new alternator bracket as my silver-top one would not, fit i see raceline sell one for 135 pound witch to me seems crazy for what is a bracket ? i am told my alternator will still fit on a new bracket tho ...

3) Idler pulley kit , £75 again seems abit dear for what it is

4) bolt my 1.8 fly wheel and clutch of the 1.8 onto the blacktop

If anyone can provide some solid info id be appreciated or mentioned anything i have not said

if you have any of the parts or could fabricate any of them get in touch

Thanks all Ryan

Hi Ryan and welcome to the forum.

I am about to undertake the same swap and its pretty straight forward.
First you will need to shorten the blacktop sump and pick up pipe,easy if you have a mig welder.
Second you need to make an alternator bracket,again this is very easy.
Third you need to make an idler pulley as the blacktop water pump runs backwards,
Again this is a simple undertaking.
There are some photos in my archive of my current silvertop set up but my blacktop
set up is the same.There is also a pic of an alternator bracket i made for my mate,with the alt
under the exhaust.
You are correct about your 1.8 flywheel,it will bolt straight on.
BTW put your location in your title so anyone close can help you out.

Thank's Andy ,

Sorry im asking so much but being as the engines new i don't want to go wrong and damage it ....

Im no good with a Mig welder unfortunately, Do you have any idea if its true silver-top one can be modified ? if not i will have to see if someone on here can use a Mig for some beer tokens

Do you have any diagram of how to make a bracket for alternator ? and will my alternator be ok on different bracket or will i need another ?

Idler pulley again do you know of any diagrams ect


Thanks for reminding me about location

Ryan

Get yourself some 5mm steel plate and make up a plate for the block and a pair of
mountings for the alt,then send it up here for me to weld it up.

The silvertop sump can be used if you use the longer main studs,windage tray and pick up from said motor.
Mind you i have never actualy done this swap.

Other members have done it though and will no doubt be along soon to confirm it.
Send bigwasa a u2u,i believe he has done it.

My advice is to dump the webers and go for something like bike carbs for the easy option, the webers will cost you a lot to run and you will have no low down torque.

Thanks Mad teg , don't really want to go of subject .. Butt

i need to get the engine in first mate or ill have no torque

i have thought about bike Carbs but they are new to me but ill worry about that when i get there ..

But just to here your thoughts do you think bike carbs are better than webbers ?

Lower hp on bike carbs ?

better or worse on fuel ?

Any ideas if my mega-jolt ignition would run it ? or do i need a ecu ?


Ryan

At the minute i am running megajolt with Zx9r bike carbs
on a home made manifold. It works superbly and the carbs never
go out of tune. IMHO they are better than webbers.

Megajolt and an edis will run your sparks just fine.

Andy.

Silver top sump will need four 20mm steel spacers, the rest of the bits will be on your silver top.

The black top sump may have a plastic or steel pick up pipe. If plastic you would need a steel one and that could be tricky to find.

I love the look of the webers but there not ideal on a zetec. They may work if you play with them. Bike carbs are an option But once you have gone fuel injection you wont look back.

Lots of ways to mount the alternator.

The more you can do the less it will cost.

Bike carbs appeal to me over injection as i can imagine ill have a big cable of spaghetti once you go to injection way beyond my knowledge ...

ill have to find out what my webbers are worth flog them and reach into the penny jar but like i say ill get my new engine in before i look into other things ....


Ryan

Sorry went a bit of topic, When i did mine from silver top to black top i used the the sump fo the silver top that i had already cut down and the pick up pipe as well, the fly wheel will swop over as well, the only thing i had to fabricate was the idler wheel for the fan belt.

Strontiumdog on here has been modifying sumps, don't know if he (or she!!!!) is still doing it, fire off a U2U

thanks again everyone...

norfolkluego the u2u says the user-name no longer exists but cheers for that .

Advise now will be needed on the idler pulley and alternator bracket for now any diagrams,pictures would help as cant say i really think i can make one from scratch ...

i have sent a few usu messages to people that used silvertop sumps on a blacktop and hopefully as-long as they have not had problems with them ..... ill be confided to use mine and get that done ... saves getting someone to shorten the blacktop one so ill have a few more penny's for changing the webbers ...


Cheers

Anyone got any help info for the idler pulley and alternator ?

or does anyone make them up ?

is it better to have the alternator under the water pump or on original side is the following type or design a good one ?

I could make them up for you but i would need
the alternator to do a proper job.you will
need the ribbed idler pulley as well.
