duratec tuning
Hello all.
My next door neighbour is building a mk2 escort for some race series and needs to get the maximum power out of a normally aspirated ford engine.
He's decided to go for a 2.3 duratec and has been browsing the tuning sites and found you can buy engines ready to go at up to 304 bhp, but at a
price of about 12K. He is prepared to spend decent money, but preferably not that much! So, what does he need to do to get that sort of power from a
duratec, and what gearbox should he get?
Thanks for any help
Hugh

That page is quite interesting, with some good links. The principles of tuning are generally the same no matter what engine is used.
If it isn't broke, fix it until it is

without a supercharger or turbo i would say he will have to spend a bit. i would say he has to look into a Jenvey or Omex Throttle body system with
BIG chokes! uprated internals for sure, and uprated cams, big valves, porting etc etc

Thanks

300bhp from a 2.3 isnt that difficult and certainly doable NA. The thing to watch with the 2.3 is that you start with the right base engine as one
sort has a balance shaft and one doesnt. You want the one without!
Scholar Engines produce some mean duratecs
http://www.scholarengines.co.uk/
For that sort of power you will looking at a decent amount of head work (£1200+), cams (£500 + another £300 for springs and followers), forged rods
and pistons (£800) and possibly an overbore too. On top of that you will need all the normal stuff, 50mm+ throttle bodies + ecu (£1500), flywheel and
clutch (£500), bellhousing (£250) and heavy duty type 9 box (£500)
Ebay is your duratec tuning friend. There are a set of scholar 270bhp cams for a 2.3 on there at the moment for £250 which is a bargain.

People over on the Turbosport forum have n/a Duratecs with new cams, pocketed pistons, some headwork (standard valves) and TBs showing 270bhp on the
rollers.
If you want more than this it seems to be where BIG cash is needed.
Anything more needs more revs = uprated internals etc.

Wow, I'm impressed by the raceco site - will pass that on to shaun asap. Its quite nice helping him - he has load of money to buy all those bits
I have to bodge somehow, but I still get to play with them, but don't pay
I'll let you know how it goes and what we finally get out of it
Regards
Hugh
