So a std st170 bottom end will take 350? I think I might have to build a zetec!!!!

No need, OFAM can use any TPS and other sensors too.

Question...
Just about to buy megasquirt and install parallel to my focus ECU. Do I need to buy the fan outputs or will the standard ECU control this fine still, as it still has the CTS reference?

And if I were to go ahead and buy them could I splice them in together with the old loom or would I need diodes to prevent damage to the ECU?

Cheers!

What cr will you get with this st170 bottom end and head? would you use a stock head gasket

RS-Rikki

No use a 1.8mm head gasket

studabear

Are they available again?

As it's been mentioned about old ford wiring being pony etc I'm deciding to go with megasquirt ms2 and just start with fresh wiring, which also entitles me to use all blacktop inlet sensors etc. Can I use an escort RS turbo air temp sensor as il hav plenty of them about me.

And are the vxr injectors literally plug in and play, no adaptors or cups to sit them in? I do hav some Nissan 200sx injectors (330's or 360's I think) can I just use them? If so il chuck them in the inlet and bolt on a frst fuel pressure reg, then inlet goes on!! Management will then be purchased!! 👍
Sorry bout all the questions but I'm in final stages now and if I don't need to pay out for vxr injectors as iv got 200sx and ain't gotta buy air temp sensor as can use RS turbo one then il be ordering management!
Massively appreciated!!!!

What compression ratio would i get using this gasket with the st170 bottom end and the blacktop head

studabear

read the first posts of the thread.

Yes they are as my mate bought one last week from ford to do this very conversion.

RS-Rikki

Doing this conversion at the moment hopefully have it done this week so I'd of done it in 2 weeks that includes sourcing parts

RS-Rikki

I got one of ebay 145 quid

RS-Rikki

Think your better of using vxrs I do have a set actually for sale

Yeah use rs turbo sensor put a boss in the solid boost pipe

studabear

Ouch £145.

Have you got the engine in the bay yet?

studabear

Just to add I used cossie air and water temp sensors as they easily sourced and the data for the management is on big turbo.

RS-Rikki

It is a pec one but only thing I could find

Hopefully Wednesday I'll post picks it's making the inlet fit and wire it up I'm worried about :-/

studabear

I advise you mod the ledge on the inner wing where the engine mount attaches to make some clearance for the timing belt guide pulley.

RS-Rikki

Ledge what you mean u got any photos?

studabear

Will have a look on pc tomorrow

xrmalin

Ouch indeed I think my mates was only £70 straight from ford

studabear

This is before the ledge was trimmed. The gap between the tensioner and body closed further when I fitted the vibratechnics gearbox mounts.



You wanna cut a bit out like this. Can't get a actual picture at the minute.



Hope this helps.

HaggisTurbo

Wow that is pretty close lol

RS-Rikki

Shit me!!

Ok I'm on it

Right on the inlet there's a like a metal pipe that runs off with a flange do I just block that off?

Anyone got any pics of there sump mods gotta try guess where the 2 drain plugs for oil return ect

studabear

My rear breather turn was very close to the driveshaft so I had to have a 90degree bend as soon as the hose attaches.

studabear

Just to add my pictures are just how I did it.

RS-Rikki

Ok cool any idea on the metal pipe on the inlet?

studabear

What inlet?

RS-Rikki

Mondeo there's like a metal elbow? What did u block the holes up with?

studabear

Stick a picture on. Mine had a couple i blocked, they had pipes on them i blocked them with bolts pushed in with rtv sealant and hose clips if my memory serves me well. The other outlets I used for boost gauge and map sensor.

RS-Rikki

Am I right in thinking silvertop rocker covers fit? Does the rs one fit? Or even the st170 has a breather pipe just want the extra so can use a bailey oil breather

RS-Rikki

studabear

Silver top fits,read through entire thread you will see mine with extra port added. Pipes in your picture i didn't have, they look like fuel pipes? I used focus rs inlet, throttle body is bigger fuel pipes are diff too I think?

RS-Rikki

Is there any guides on fitting a cam belt never done it before I know usually u can lock them ect but different bottom end to head ect little bit daunting all this money could go down the pisser in a instant :/

studabear

Haynes manual for focus or mondeo or autodata will sell individual info for about £8. I advise you buy the timing tools for blacktop zetec about £12 on ebay.

RS-Rikki

Yeah but that's just lock off tools surely the cams need to be position properly for the bottom end

studabear

If everything is locked in correct position then it is timed up. If your not sure what you are doing find someone who does and get them to help you.

studabear

You lock the crank aswell as the cams.
