Hello don't now if this is quite the right forum for this topic but I try here.
I'm just planing for a engine swap for the next year in my -88 Sierra.

Currently I've got a pinto with cosworth pistons and rods running currently 21psi of boost with a holset h1e but the turbo is a bit laggy and even though I'm going to increase the boost to about 30psi it will be not meet my power goal and it will need some real headwork for alot of money to get there and its still an old pinto.

So, I saw that burton had bellhousings for the type9 gearbox and Duratec. I've searched if some one has turbocharged it but have found most lowboost builds with pre-fb kits to about 250hp. I'm not looking for a race build with forged internals.

So is there some one that has pulled some power with stock internals?
The engine will be untouched other then maybe lowered compressionratio with the same turbo, homemade intake/exhaust manifold. Today with the aftermarket EFIs and the e85 fuel we've got it seems you can get the powers I'm looking for with almost every stock engine if you run big turbos that is nice to the engine when you get the boost a bit higher up. For an example, here in sweden its quite popular to turbocharge the bmw m50b25 to over 500whp unopened.

Are you taking about the Duratec/Zetec out of the Focus ST170 or the 2.0 Duratec from the Mondeo?

The real Duratec as in mondeo, zetec has the manifolds switched to the "wrong" side

Ian Howell of Area Six here in the UK has done a lot with the Duratec

He managed over 500 bhp but had some problems with the block cracking or something and that was with a custom steel crank, steel rods and forged pistons. Not sure of the spec or what happened to the engine but the project was scrapped and the car sold on as he wanted over 800 bhp but to get that it would of been very expensive.

i have a steel block strengthening plate left over from a Duratec build .

lunchman

That doesn't sound so promising if that happens with that spec I'm looking for 350hp at the wheels minimum. It's in the reach with the current engine with another camshaft but to get a nice power curve will need a real porting job, the duratec wouldn't.

Might be worth speaking to Ian about his duratec build and if there are any ways to avoid the issues he had, he might have some bits left from it aswell,I know he dosnt have the exhaust manifold any more because I have that

350 bhp, stick with a cosworth engine or zetec, no reason to go for a duratec engine IMO.

When I was deciding what engine to fit in my mk3 I spoke to Ian about building a duratec and he said the same, for the money that's involved in making a big power duratec you could build a bigger power zetec, that was a few years ago now so things might have moved on in duratec development

Johnny Knoxville

Jamsport has done a lot with the Duratec doing 2.5 conversions and supercharger conversion with about 400bhp

lunchman

That sounds a bit better!

"With this kit fitted we have seen power at 320bhp with a stock bottom end. We would advise the use of a Cosworth inlet manifold to take full advantage of the power available from the Stage 2.5 kit."

if you want proper power

Yes I've seen them, my friend has a Volvo Evo engine from him in his rallycross car, but race engines wasn't what I asked about, I just wonder what powers people have taken out with the stock internals.

if your after a duratec engine to turbo why not look round for a mazda 3/6 mps engine as it's a 2.3 turbo lump straight out the box so should be good for 350+ and with a bit more safety factor built in

/\ i believe the bellhousing on the gearbox is a different pattern to the ford ones, so can't just connect up a ford box.
or at least that has been a problem for a mk1 fiesta using a mazda duratec engine anyhow.
my choice for big proven power and reliability would be a 200block with steel rods and forged pistons, easy to take big power, couple with a t4 you'll be fine for plenty of go.

on the other hand zetec turbo's can be done quite cheaply and there are quite a lot running over 400bhp, some into the high 500bhp and maybe some out there into 600bhp+

lunchman

Yes the pattern is different but burton have bellhousings for it as I said above. YB isn't a option.

Beach

Can you not use a mk1 Focus RS engine ?

With the correct turbo and management that sort of power isnt a million miles away and this engine has a much better head than the zetec's if im not mistaken?

Ben26

Life would b alot easier if you stick with the YB alot easier to get big bhp. but then on the other hand the only good thing about the 2.5 duratec from the Mazda MPS is that thy have steel internals including crank.

I'm pretty sure the oil pump went. After all the money he spent I'm not surprised he fucked it all off.

Does it need to be ford?

If not its worth considering the C20LET/Z20LET engines from Opel, they will fit to a cosworth T5 box with a readily available conversion bell housing.

lunchman

The reason why I thought of the Duratec HE is because it is a "Ford" engine. Got to look in to the Zetec a bit more, but I don't think I've got the space for a big turbo, wastegate and downpipe on that side(you know we got the steeringcolumn and master brakingcylinder on that side)

If it won't be a ford engine I think I will go for the BMW M50B25 realy much bang for buck with a realy nice sound.

BMW lump sounds a good plan.

i would love to turbo my m50b25 but the steering column gets in the way for us here in the uk

Johnny Knoxville

He was running a dry sump with the Duratec

Here is part of the engine spec

DKE crankshaft, Arrow Rods, Custom Pistons, Ductile Iron Block Liners, 2" aluminium lower girdle, 1.75" 321 Stainless Exhaust Manifold by ALUNOX, Custom 8 injector inlet, Custom profile cams, Double valve springs, CNC Cylinder head, Pace dry sump Turbonetics T72 Turbo, 46mm Turbosmart wastegate, Pectel T2 ecu

i'd like to fit a evo engine in a fwd ford but not sure what gearbox could be used

Johnny Knoxville

Someone put one in a 205 pug didn't they?

zetaboostboy522bhp

ians engine broke a piece of metal about 3x3 inch in size off the corner of his block , it just cracked and fell off lol, people say it was because he used liners so the machining of the block weakened the walls but ian said they only took around 1mm to fit the liners to the block so he couldnt see it being that . he then looked into buy a block from america which i believe was a mazda engine but it was a custom drag racing block that had all the waterways filled so the $8000 price tag and the machining of the waterways put him off and he sold the parts on , i do know for a fact that the engine build was in excess of Ł40,000 so it must of been playing on his mind to build another and knowing ian really well its not like him to give up but he did so that must say something.

Modified Evo box I guess. Unless you wanted to water cut a adaptor to a mtx75 ?

ians duratec was a monster or a build with all the best parts money could buy on it, for example the exhaust manifold made from 321ss pipe cost thousands to design and make, 40k is slot to lose in a build and I think any one would have done the same

evo engine and box, custom shafts is all you'd need, positioning of engine and box could be the arse bit though.
shafts made for less than Ł200 though, just a case of measuring and having cv's read.

My mates mate has the evo engine in his 205,and he using an mtx box mate so if your intrested incan see how much he wants the the adaptor/bell housing whatever he made it to fit with mate?

So 500bhp out of a duratec is a bad idea?

robp-tt

iTrader: (1)

Its not a bad idea as there are a few around at that power

xr2wishy

iTrader: (2)

not a bad idea at all, just may cost a fair few quid to get the power out of them, considering off the shelf parts are everywhere for yb and zetec turbo setups.

zetaboostboy522bhp

its one of these oil pump questions lol , personally i know ians engine was a corker and made some serious bhp at very low boost but it ended his block simple as that , now ive seen a few supercharge duratecs running around 400+bhp so i would say 420 bhp and no more because i personally would be squeezing my arse cheeks together running more than 25psi throught that block , every duratec ive seen turbo charged is running a nice amount of boost eg 20 psi . having good parts built like your manifold etc will gain extra bhp without slamming more boost into the engine so you might reach a good figure with a relible boost pressure , what that is , is anyones guess
