Pinto to Duratec Conversion
Hello all,
First off please allow me to apologise if this has already been covered. I did a search but couldn't find anything obvious. Please feel free to
point me in the right direction if need be!
Anyway, I will soon have in my possession half a Tiger Avon race car. It currently has a wheezy single cam pinto engine and we are wanting to replace
this with a duratec or similar. The goal is 200bhp and this will be achieved using throttle bodies and ECU.
So, my questions are:
How easy is it to fit the duratec to the pinto / avon chassis?
Will the Duratec bolt up to the Type 9 gearbox with ease?
Is there anything crucial that I'm missing out on here?
Any help would be greatly appreciated.
James

Hi James
I'm embarking on this journey right now, and am very happy to help/collaborate. I'm keeping aspects of my transplant on the forum (just
search for my name - nearly all my opened threads are about this) and I cover off in some detail what I'm doing on my blog as well
(Furyrebuild.co.uk). Also, check out the flakmonkey thread
There is considerable work and expense to undertake, but it's not difficult.
From my experience, you will need:
- to plan for fuel injection; low and high pressure pumps, swirl pot, regulator, vent valve, tank.
- swap to a gated sump designed for longidudinal location. check out this
flak monkey thread. I have tig-welded my own, and will make them for others with flak's blessing
- plan for different engine mounts - fastDan sells all you need; i've used his parts and they're very well made. I made my own (see the
blog) but they're not something i'd do for anyone else; my approach means having to have the car in situ
- check out SBD Developments for all your engine internals; big-end bearings are weak when you start adding the power, and when you get to 200bhp you
should be keying your crank as well. They're very good to deal with; prices are fair.
- you can modify your existing exhaust, or people often fabricate their own.
- check to see what the regs are on catalytic converters
- I found the duratec has very similar dimensions to the pinto so slotted straight into the same gap.
- you will need a new bellhousing to mate engine to gearbox, and they're not the same. I also found the new bellhousing was a little wider,
meaning i had to modify my footwell.
- the standard flywheel is not up to the job, far too heavy and the dual-mass arrangement is prone to knacking. get a lightened one.
- the standard alternator fits fine on my fury, but for a 7esque, you may need to relocate. I have a spare that mounts on the other side (nearside)
should you require it. It's a smaller denso unit from a honda, and has the mounting brackets to boot.
- I ended up with the engine at roughly the same height as before - good for routing your steering column. If it's tricky on your current
build, expect the same issues
More than happy to chat.
When all you have is a hammer, everything around you is a nail.

Hi, I did this last year and whilst there are a few little problems there's nothing that is too hard. All my notes, questions etc were on the
Tiger Owners Club Website and a few of the links are below:
My thread asking for general duratec info:

General Duratec Upgrade thread (alot between me and another chap having similar problems):

General Issue with Type 9 to Duratec bellhousings:

Engine mount and engine height problem and solution:

My header solution using the original pinto headers:

Duratec clutch cable issue (go hydraulic if you can):

Tiger Duratec engine mount info (I actually had to get these remade as they weren't quite long enough):

Hope that helps, fair bit of reading but should give you most if not all info. If you need anything else give me a shout.
Mark.

Thanks for the advice chaps, I'm posting from my iPhone ATM so will look in more detail later. Looks like quite a job. I take it Zetec is no
better? Still need 200bhp!

To get the bigger power in a Zetec it will cost a lot more than a duratec.

If you are after 200hp Duratec is the way, you will need Throttle bodies and will need to change the cams.
I am expecting about 180hp from mine but I haven't changed out the cams.
Look for an ST150 engine as these come without a duel mass fly wheel (which is good) and the EGR is already blanked off.
Getting the clutch sorted is quite tricky, I ended up with an RS Turbo uprated pressure plate, Pinto racing friction plate, SAAB thrust bearing, with
hydraulic cylinder.
Using a Megasquirt 2 V3 ECU with no EDIS.
Duratec Engine is fitted, MS2 Extra V3 is assembled and tested, engine running, car now built. IVA passed 26/02/2016

I'm currently building an Avon with the Duratec. I'm using GSXR 1000 throttle bodies and Omex 600. I found that I had to relocate the
alterator on the offside of the engine as it was hitting the chassis rail. I made the engine mounts, which if you can weld are quite straight forward
(but I am a plater by trade). I'm having a custom exhaust made in a couple of weeks (£1000 inc cat) as Tiger told me that their headers
wouldn't fit and would need modifying. I also have some cams to go in after IVA.
To be honest I got all my info off here and the Tiger website. Some very helpful, clued up people around the forums, so any questions just ask and you
have very swift replies!!
