Story is:
I own the series 2 in my sig it currently runs a 2.0l zvh standard head and cam, bottom end has st170 rods and pistons with a 1.5mm de-comp plate. The block has the neccessary ARP in it as well for piece of mind. Its currently running around 170bhp but i wanna get around the 250bhp mark.
Would i be best going for a full blown zetec turbo or could i get good results with efi, cossie management, hybrid, intercooler and map?
Any opinions or advice welcome.

Aint st170 high comp pistons???

drsrst2zvh

Hence the de-comp plate, you are right tho and the compression is prob a lil to high i get 150 on each cylinder.

for me id stay with what you got fella,

swap out the pistons and plate for good low comp pistons ,

cam , cossie management ,gud turbo and intercooler ,

will see 250 eaisly and a gud lump of torque ,

but budget in a deecent box and brake mods,

all power is usless if you cant put it down ,

beef

p.s you doing the work yourself

drsrst2zvh

Yeah will be doing all the work myself with my bros help already have a cossie brake set-up waiting to go on i.e 4pots and rear discs.
And my brother has just re-built a standrad box with the bigger bearing conversion so will see how that lasts.
Also just out of interest will a set of c20 let pistons be better than n/a xe ones and also will they fit on st170 rods if not ill have to source some standard zetec ones.

not sure mate ,

but you can pick up wossner pistons for a gud price , i know someone who can do a gud deal on them ,

get them to the comp you want ect ,

what turbo you running ?

Ive also seen JE pistons cheapish as well around the 350 mark.
Its currently just got a standard t3 on it but was toying with the idea of a cossie t3 from a 2wd saff. wanna keep the budget quite low. if money no object id throw a t34 at it. hows yours s2 4x4 coming along anyway?

slow lol , working on other projects that have to be completed quickly ,

but once thats out the way in a week or so ill get bk on with it ,

for me id save a little and go for a 34 mate, they coem along all the time ,

i recently sold a like new t35 for only 300 ,

if your wanting a price on wossners let me know bud ,

got 250 out of my zvh with forged pistons @ 18psi, also had 300lbs/ft and efi was a quick car

Rick

What boost are u running for 170bhp? About 6psi?

hi mate speak to ian howell at fiesta frenzy/area six motorsport hes the best bloke to speak to . he invented the zvh engine conversion so hes got a list of components ,pistons , rods , big valve heads , inlets , turbos , basically anything you need to uprate your to 250bhp
i think a 1mm overbore and a set of low comp pistons to take you to a 2.1 litre you would see 250bhp @ 15/16 psi easily, just give him a bell mate hes a very helpful guy! tel:01522 877887 tell him paul sent you from derby
hope this helps

Would you advise EFI then? or stick with MFI i have majority of the bits from a FRST i broke i.e inlet and fuel rail all sensors etc... What management is best cossie live mapped i suppose is the easiest?

drsrst2zvh

just over a bar i had it on the rollers at PE about a year ago and the actuator had no preload it made 156 bhp but 241lbs ft of torque. the actuator has about 5mm of preload now so holds over a bar so im guessing at the figures.

drsrst2zvh

Cheers mate i will ring him when im back in the UK next week.

The question I genuinely have is regarding the size of your budget?
I do not believe you can do 250bhp on a Escort and make it reliable on the cheap which your engine spec currently appears to be. You have to use quality parts.

Before considering changing management I would throw away the decomp plate and get some decent pistons in it along with a ported head and cam or at least use the 16 valve head as this flows a great deal more than the standard 8v head.

drsrst2zvh

Indeed as you pointed out very clearly the last engine was biult on the cheap but has been uber reliable for the past 24months with not one issue i am now in a position where i can build the car up over time and spend more money on it.
After talking to a few people i am thinking to aquire a new 2l engine and have a set of c20 let pistons fitted and to get the head ported and polished by a local engineer. Have also seen an extremely nice tubular manifold from the states and am holding out for a t34 or t35.
What would peoples advice be on management? as i know this is an area i am extremely green on.

zetaboostboy522bhp

reilabilaty is always an issue and in my opinion you should try and use custom management depending on your budget. there are lots of good quality systems out there on the market but the one ive used and tuners like harvey gibbs and ahmed bajoo use/map are more than likely to be pectel. the pectel t2 ecu was designed for the zetec engine which was used in the formula ford racing series so is perfect for what you would need. my 2.1 zetec turbo made 522bhp on pectel and there are alot of cossies in norway making good (500+bhp)power using the t2 ecu,
again give ian howell a bell!

drsrst2zvh

How difficult is that to use and set-up i mean i have no problem installing the management and i would more than likely take it to a specialist to be mapped. How expensive is this management?
