Just a quick question

thinking of using a rover turbo inlet manifold for my zt conversion

wondered if someone could tell me which injectors can i use with this..?an does anyone know where i can get an adapter plate from for it to fit...or will i have to have the head tapped ?

Cheers

[luckettfrst]

dunno bout the injectors but the adaptor plate http://www.fiestaturbo.com/forums/rover ... -vt148988/

just finished mine altho not the rover turbo one, it was a m16 one, the silver coloured ones. Slightly different to the black ones, as the bolt holes are slightly different positions, but basically the same lol

neway, what i had done was had a steel plate made so the lower part of the rover inlet can bolt to the plate then the plate can be bolted straight to the zetec head. Any local engineer place should be able to do that for you, cost me about £30 to get done. The fuel rail is top fed, so any top fed injector should fit, the rover uses bosch injectors so anything like frst or cossie ones will fit.

top half also needs to be modded aswell tho, so the bend can clear the brake servo, some poeple reangle the bend, but i just had mine cut off and a plate made and welded on so a my cossie tb can bolt to it

hth, few pics for reference...

[mrorange2]

looks good mate where did you get ya plate done dont suppose you can get one for me? how much did it cost ya to get the inlet cut and welded up?

[SamT]

bought the inlet £25 with fuel rail and injectors.

umm was £30 for the adpater plate, but he also welded up the end holes then moved them slightly further in as part of it gets in the way of the zetec bolts, you see what i mean if you look in the for sale thread of the blue one like mine, they have just chopped the ends off so not a full circle on that one.

and the £50 to have front cut and a plate welded to mount the cossie tb with a few holes tapped into the back for sensors and vac take offs.

tbh mate any engineering place will be able to make it for you, i just took them a zetec gasket and the lower rover bit and they done the rest lol

[mrorange2]

okay mate cheers for the help anyways! think i need to get a rover fuel rail

that blue one has to injectors per inlet so no good for me as wanna run just 4 not 8 lol.

[mrorange2]

do you know if this will fit a zetec turbo and run cosworth injectors?

[SamT]

no they wont, iv measured the ports before, same idea as you lol, the ports are way out

[White2i]

have a look on http://www.oddkiddcreations.co.uk jano sells the adapter plate for a very good price and they very very good quality

I'm fairly sure you can drop in EV1 style injectors into that manifold (cossie, frst, etc).. Thing is, why would you want this manifold? The standard zetec (130PS) one is good to over 350bhp..

[mrorange2]

We are using the 130ps inlet manifold now with 200SX injectors.

The fuel injector holder on the zetec manifolds is not air-tight so will cause air leaks..

What do you mean?????

Right, you know the piece of aluminium that your fuel injectors are bolted to? This then gets bolted to a sandwich plate with 3 bolts (on an aluminium inlet).. These two do not form a boost-ready package..

[mrorange2]

Okay even if i'm using the RS1800 inlet manifold?

[saqmaster]

All of them.

[mrorange2]

:s i'm confused so your saying if i use the RS1800 inlet manifold and fuel rail i'll get air leaks? What injectors should i use then as looking for over 250bhp.

It's not the injectors that leak (although the o-rings on the Nissan injectors are wrong, and using the Ford ones is bad too as they aren't a proper fit).. It's the fuel rail itself that leaks (air).. you can get round it though.. you just need to use a bit of injenuity

[mrorange2]

go on then let us know how to get round it?

[saqmaster]

Well, if you want to be proper, you'll get some adapters machined up to go on the ends of the fuel rail to seal against the manifold.. o-ring'd perhaps.. o-ringing isn't too bad on the plastic manifolds, but a bit of a squeeze on the ally ones..

eg:

The fuel rail will not leak air. Ford would not design something that will let air in after the TB.

The reason yours probably leaked was that the manifold holes had become corroded/oxidised.

Oh right. I assume you've pressure tested the manifold package at 2 bar then?

[rowdyburns]

If you have a metal on metal seal that is held in place with the tension from 2x m6 bolts and it is air tight at 30 kpa (vacum) it should be still air tight at 300 kpa (2 bar boost).

[mrorange2]

I'll be okay at 1 bar then

[saqmaster]

It's amazing how people err on the side of the most-accomodating forum answer

[rowdyburns]

I guess the answer is try it first as normal and use your compressor to do intake pressure test with soapy water to check for leaks.

[mrorange2]

i'm not saying your wrong mate just i dont have the cash to get what you said done my pockets are empty now and i still need a few things lol

[saqmaster]

I didn't actually say what you had to do to fix it.. I just said you need to be a bit creative.. on the Aluminium manifold, the fix is actually to use two sets of the seals that fix onto the bottom of each injector outlet and modify the second set to invert them.. it's a cheap fix..
