I'm currently faced with a dilemma that i need some advice from the kind owners out there.

I'm un-sure whether i want to go full zetec turbo or ZVH.

From how i've got it in my head, the ZVH will take more work on 'the engine' but alot less work on 'the car' to adjust it to accept the engine, and if i've approximated my costs correctly, i will proberly be significantly cheaper conversion. (2000cc Zetec E Block BTW). Also i expect that a ZVH conversion will mean the cars off the road for less time than if i tried a full zetec conversion.

I guess i'm asking if its worth going full zetec turbo for the extra costs involved??

Any help/advice greatly recieved

Thanks

bUY pAUL r'S MOTOR, AND GET THAT FITTED!

[StreetDragster]

Already got a 2000cc zetec engine and no cash for that fine motor!

if u have a mint head, like a stage 3 big valve and cam and stuff then ZVH, if not then Zetec Turbo :D:D:D:D

What do you have listed for the extra parts and expense for the 16v?

You'd need to re-tap the head for the ex manifold, but you'd not have to block the oilways.

If you use adaptor plates you can re-use the FRST inlet and fuel rail, crossover pipe etc.

[StreetDragster]

Well, i've gathered from the many posts on here the following-

i'll need inlet adaptor plates at around £60ish
i'll need to get a fair bit of piping for coolant system modifications (cause its the little things that really bump the cost up i've learned), i've allowed another £60ish
i'll need spacer blocks to lower the crossmember and engine cradle 10mm ish, i allowed £40 for these.
the head will need aluminuim welding, drilling and re-tapping on both sides for the correct manifold patterns, which i'd want a machine shop to do. I've allowed £60 for this. I've also gathered that as long as chemical metal is used on the studs that break out into oil ways there will be no leakage problems.
i'd be fitting a cam kit at the same time with a vernier pulley, i've approximated £350 for these for the zetec (guessing one cam so half the price for a ZVH??)
i also approximated the zetec head gasket to be a touch more expensive than the ZVH's.

Does that sound about right?

I have another question about boost pressure, i should proberly start another thread but i'll put it here anyway.

I plan to use 86mm accuralite or similar forged pistons with a stronger head gasket and head porting/polishing. In either a full zetec turbo or a ZVH. I have a stage 4 T3 hybrid turbo which i'm fitting to which ever route i choose to follow, plus a GRS intercooler and rad. I wish then to use standard crank, rods, bearings, shells, valves, manifolds, management (OFAB) etc I intend to have motorsport developments map the car to whatever fuelling it needs and i will fit whatever sized injectors it needs. What boost can i expect to run on these components?? (Assuming fuellings not a problem)

Thanks

Stage 4 T3, which company made that?

[AdrianFRST]

What I would do is go 16v, but at this stage forget about:

Cams
Cam pulleys
Head work (other than the necessary mods for the manifolds).

That should free up some of your budget, yet at the same time you have the potential for more power later on.

Assuming you went ZVH with a mildly worked head (£400), cam (£150) and pulley (£80), that's £630. Take off your £240 for the 16v mods and you've got just under £400 now spare which I'd put towards better pistons or even steel rods.

Paul R's engine is on the standard head, cams and inlet and is producing very good times.

I think with that spec you'd be looking at around 20psi.

There is also the potential to take it to the max with the FFM Rover or Zero-Loss inlets, tubular manifold and T34 etc.

[StreetDragster]

Right, thats great advice thanks.

Ian, not sure ont he make of the turbo, i've bought it off ChippyFrst off here and it should arrive in the next day or two

Thanks

Upto you really

THe 16v is the better conversion.

I can supply 2.1 ZVH pistons (could also get 16v ones, but jus sold the last set to Ian.........

16v is better, by far, not many people if any will disagree.
