Hi all, Im new to passion ford and new to modifying in general so I have a lot of questions regarding putting a turbo zetec into my mk4 estate, Okay so first of all I plan on using an ST170 block that i already have and using a 2ltr blacktop head from a mondeo or focus, and using the ST170 valve springs, I plan on going omex 600 to control everything, I want to use an IB5 from a Ka as Its just too expensive to go mtx because of the custom driveshafts, Does anyone know if an IB5 will mount as Ive only seen them in mk4's with cradles but Im using a S1 ARB, I have CVH parts so I dont mind using an RST exhaust manifold, Also what turbo will I need? Will the RST one do? I want to be running anything from 230 to 270 reliably, Will an RST flywheel and clutch work fine using a Zetec and IB5 running that sort of power? I would like to use a Rover inlet and Cossie throttle body but I dont know where to find the rover manifold? What kind of inlet options do i have? Id much prefer a side feed inlet. Any help is greatly appreciated and I realise this might seem a little ambitious for a first build but its a long term project so Im not too pressured, Thanks

Edit: Also does anyone know if the Puma Linkage will still line up relatively close to the standard one after an IB5 swap into a mk4

A good few of your questions answered in here.

Thanks, I will take a look now

Ive read that guide and a few others before, Do i really need to use the)same clutch since theres a 100bhp or so difference in power between my desired amount and his guide

studabear

Mines made 293bhp at flywheel 247bhp at the wheels and my clutch is holding me back.

combi_zt

What kind of setup are you running?

studabear

Luk cover with a Alcon 6 paddle friction plate.

combi_zt

Is it slipping or do you think it just isnt up to more power?

studabear

Slips if launched hard when it's hot.

Ah I see, Im not too troubled about the feel of the clutch as long as its not some full blown racing clutch, Id like something strond and reliable and doesnt break the bank, What gearbox are you using?

studabear

Rs turbo box till it breaks then it will be onto a ib5 or mtx conversion.

combi_zt

Going IB5 directly after is a good and cheaper option because you dont need to get new driveshafts, you can use rod linkage, and the LSD from your RST box will drop right in, Id love to see how you go about mounting the IB5 if you go that route, although nkbody can argue with the quality of an MTX

studabear

I've a couple of ib5 boxes and a mtx stashed away. Plan will be when the current box dies chuck the front starter box I have in then have the rs diff fitted in the escort gti rear starter box with all new bearings etc.

To mtx it will be a couple of grand I reckon, esp as the bay will need painting once the mounts are all welded in etc.

combi_zt

Yes I agree, I was hoping mtx but i was gone off the idea as soon as i heard custom driveshafts and there is no LSD that i can pull out of a later escort so just too much on my wallet, i think the money is better invested in just getting the engine running right after building it
