2L Blacktop Zetec Turbo

[DeanRudkin]

Hi guys just thought I would start a topic as I'm just getting the final parts to start my turbo conversion I'll be using the megasquirt ecu and the td04 turbo I've got my exhaust manifold with my adaptors to bolt up to the turbo and I'll be using the gbs inlet plenum

Go for it Deano

[DeanRudkin]

I cut the zetec original plenum to get take the injector bit stripped all the unnecessary wires out of the injector rail used some gasket sealer and bolted the two together ready for installation and purchased a few hoses and hose finisher clips got to keep it bling under there next step was to make the exhaust manifold adaptor plate so I could use the escort turbo which I picked up for 25 thankfully chris (tractor) had already got one so I took that and made myself one

What boost you aiming for ?

[DeanRudkin]

I'm hoping to get about 240bhp so whatever boost I've got to run to achieve that

[tractor]

mine going to bigger than yours 241bhp

[DeanRudkin]

You wish

[richardm6994]

Be mindful that you can only boost up to 11 psi on a standard n/a zetec.

Any higher and you need to up rate internals

[DeanRudkin]

Ok cheers I've been told the 240bhp is about the zetec limit that's right?

Would advise changing the rod bolts fot ARP. I ran decompresion plate with 10 psi and the rod bolts stretched. Knocked big end out

[richardm6994]

I dunno about the zetec's bhp limit, however 11psi (on the limit of boost) on Dan's saw 241.6bhp

yeah but you was running about 800bhp!!!

[speedtripledan]

The end bhp is irrelevant if you boost more than the 11psi it will be an early grave for the zetec. But 240 should be achieved

I.m running arp Conrod bolts

 

Think about the torques that's where the smiles come from

 

Oh steamer 243.6 i.ll have you know

Not doubting you as I know jack *bleep* about zetecs, but where did the 11psi figure come from? I know Dean has been advised by a well known and reputable tuning firm with a history of building and tuning zetecs that the safe limit is more like 14psi.

Who is this well known and respected tuner? Always looking for good info.
