Hi all,
my first post on the forum - this seems to be the best place online for 7 related questions, I've read a lot of really useful threads but is
anyone out there running with the duratec and the 5 speed mx5 gearbox tilted over? I've found lots of mentions of it and suggestions you can bend
the gearstick to compensate for the 10deg 'lean'
I've picked up a duratec and mx5 gearbox and am 'building up' to getting it fitted in the car but would love to see some pics of how
others have done it..
Anyone gone the other way and mimicked the mx-5 tilt on the engine? I've not worked out yet if it raises the exhaust or the inlet..
On a side note - at some point I'll have a 2.1 Pinto engine (Vulcan engineering engine) to sell, any recommendations on the best places to list
it?
thanks!

I did this albeit with a 2.0 ecoboost (same block as the duratec) I tilted the engine and kept the gearbox level. I have a ford spec sheet which
states the engine is designed to run fine up to a certain angle of tilt. With tilting the engine the inlet is raised and exhaust is lowered. If my
memory serves me correct you can actually use a Mazda sump which is sloped to match the tilt and I believe raceline make a slant sump too.
There is a guy building the same combo eng and box as you over on the wscc. Might be worth a peruse?

thanks! am now about half way through that thread.. looks interesting!
Did you consider tilting the gearbox or was that not something you looked at, and also any issues with tilting the engine? Have seen the tilted sumps
but a bit concerned on clearance under the bonneteven so? definitely easier on the gearbox front though..
Thanks Sam, useful info and pic!
Quick question - I've noticed a couple of Duratec installs with braces like yours to the front of the engine, curious on the reasons/pros/cons or
it is just for pure track day cars etc. - I'll be up front, mine is a kit so I didn't build the chassis but will have to mod it a bit for
the duratec so was wondering if I need to add something like this..?
We used the Mazda (MZR) version of the Duratec, so it came with the correct sump to start with.
It's quite a tall engine, certainly (most new engines are) and tilting the induction upwards doesn't help - especially since we were using a
quite large carbon fibre plenum coupled to a supercharger installation. It had a fully enclosed bodyshell, designed specifically for the installation,
but it needed quite a bulged bonnet to clear the plenum.

Thanks Sam, makes sense
I'm still trying to find the threads I saw where people commented about keeping the engine square and the gearbox tilted.. any thoughts on going
that route?

:-) fair enough, when I started looking at a duratec it was with the assumption I'd get a bellhousing for a type 9 gearbox. The first couple of
comments I found about the mx5 box indicated they were tilting the gearbox not the engine so that was my default assumption (like here:
https://www.pistonheads.com/gassing/topic.asp?t=1355899).
Looking back at some of those threads, they were related to putting the combo in old escorts so maybe they couldn't tilt the engine for space
reasons.
Someone also said they'd had the bellhousing cut and spun to remove the need but it sounds expensive and like that would have to be done
'very well' not to cause issues.
Thinking about it more and given your feedback I think I'll switch my assumption and assume I'm tilting the engine unless I can't for
some reason, was just curious which way people had gone. Think the priority is to get them mated up, the pinto out and have a play..
Cheers

I’m building a MNR VORTX with a duratec and mark3 mx5 box. I fitted a slanted raceline ally sump so the sump is level with the chassis and the engine
is tilted slightly. It lifts up the inlet side, and with the jenvey manifold, the throttle body trumpets are also level. I don’t know how to post
pics on here but if you pm me your email address I’m happy to send pics.

It would be interesting to know whether the MX5 NC sump will bolt straight onto the Ford engine.
Common sense suggests that it should, but there are one or two minor differences between the MZR (Mazda version) and the Duratec (Ford version) that
you might not expect.
Is the Raceline sump any shallower than the MX5 sump?
I’ve no idea about the mx5 sump, but the raceline sump was quite a bit shallower than the st150 sump that I took off.
