Hi my names Wes, maybe you can help me,

I have a sierra sapphire 2000e 4x4 I am about to start building zetec turbo for it and i'm looking for 300bhp, so far I have an st170 engine (I'm hearing its best too use these as they have forged internals but even still do the internals need too be changed for a set of steel rods and forged pistons from burtons)?

what head do i use (st170 head a blacktop head or frs head and do I need too buy some cams)? what headgasket and do I need a decomp plate too? what inlet do I use (is a frs inlet any good but which turbo/turbo housing)? is there anything else I will need. Oh and where do I get mounts from as i'm

cheers for any help it is much appreciated Wes

Ford have already produced a Zetec Turbo, so if I were you, I would sell the ST170 engine on and purchase a mk1 Focus RS engine and run it on some bespoke management.

For the price of getting and frs lump and management which is 212bhp I can build a zetec turbo running 300+bhp

Would be interested in your costings as I would have thought hte lower comp pistons alone would take you close. I am probably wrong though

Well for 1 I already have a st170 engine cost virtually nothing, a frs engine is Ł1500-2000 thats just for engine no inlet,turbo just bare engine

forged pistons Ł136.45 (burton powers) steel rods Ł177.94 (burton powers) arp studs for head and rods Ł56.00 frs headgasket Ł16.00

omex management Ł600 which I have to use weather i use frs engine or build one! I can get blacktop head for Ł50.00

James-W

pistons/rods will be priced per item, so * those figures by 4 is approx Ł1200 before building the engine etc, it soon adds up PEC do a package thats Ł800 for both IIRC, better going there than getting stung with burton tax, although I don't know what the st170 rods are capable of.

FRS engine surely isn't 2k?

What is IIRC fella and have you got Pec web address please, I had a look at frs engine and on here on ebay,gumtree and breakers they want between 1500-2000

Cheers help much appreciated

Thought the ST170 bottom end was meant to be forged or was that just a forum myth?

Your talking about Ł1200+ for a Zetec engine with forged bottom end, new bearings etc plus honing and boring.

st170 bottom end, black top head, thicker head gasket from FRS. Good for 300bhp.

just use the whole st engine, thick zetec head gasket, not sure which, just find a blacktop type one that is 1.8mm thick.
the rest of the engine is sound. Karlos G has gone this route if i remember correctly (IIRC).
if you do decide to go for steel rods and forged pistons, then hit the states for those, i got custom sized ones with rods for less than Ł800 delivered just over a year ago.

the head gasket is for a frs that has had a deck skim, there is a part number flaoting about.

Ok cheers fella where can i get engine mounts so it will go in sierra sapphire? What heads best to use out of frs,blacktop or standard st170 as i thought the cams made a big difference in performance as the engine will be turbo'd? Cheers guys

luke19790_3

use a blacktop head with the thicker focus rs gasket

luke19790_3

think you will need to make the mounts, you may be able to modify some 1.8 cvh ones?

What as in sierra 1.8lx cvh

Only reason I ask about which head with cams to use is because KARL said in a recent post:
There are many ways to design such a 300 hp zetec turbo engine:
1 - bigger cams and much more rpm - thus lower boost required to achieve 300 hp.
2 - factory cams, restricted intake, low rpm - thus much higher boost required to achieve 300hp - more prone to self destruct.
3 - High flow heads, intake manifold, and exhaust manifolds, high efficiency intercooler, performance cams etc.. = now really low boost levels to reach 300 hp.

Have you got any places I can try to get the steel rods and forged pistons from whether it be uk/states and (what ones do I need sizes etc..)?

cheers people

nevsrevs

pec do rods and piston packages, standard cams are fine for that level, a blacktop head and cams will do 400 bogo, just go for a good turbo and intake package and your piss 300

doga-ot

iTrader: (1)

what is pec's web address? I benn told not too use a small turbo as more psi will be needed and end in blowing engine so any ideas on turbo and inlet?

cheers

help people what forged pistons/steel rods do i need (e.g sizes and or do i get frs forged/steel ones or 2ltr blacktop forged/steel ones) cheers

nevsrevs

depends on your block mate, 86mm is norm i think, if you search PEC pistons on google, i would use a custom intake, like a area six inlet, or better still go on the area six web site, this is ian howell, one of the best in the business with zetec turbos, as for low boost, if your going forged than 2bar is possible

doga-ot

iTrader: (1)

ok fella I'm using st170 block so what size forged pistons/steel rods

cheers

nevsrevs

check the bore size to make sure its standard size, then get the next size up of piston, as i would not run standard size piston, always get a overbore.

What sump do I use as its going in sierra

thats out of my relm mate, im a fwd man, p.m. fudgey as he has done it.
