Basicly i want a 300bhp zetec turbo...

I want it reliable as possible but just unsure what spec to go for. Bottom end will be forged. Its a silvertop by the way and its got a focus rs gearbox so thats not an issue.

Managment?
Inlet?
Exhaust manifold?
Turbo?

And this oil pump failure is worrying me! Dry sump or not?!

I need to decide on a rough spec as i havent got a clue what to go for?!
Any input would be great

Matt

crazycage

rover inlet
a good exhaust manifold
t34.48
dry sump if you want but not really needed at that power
and some up-rated valve springs job done.

Oranoco

Pretty sure my mates spec was very basic at 316bhp, RS1800 inlet, Escort RS Turbo exhaust manifold with Cossie turbo (can't remember the unit itself though). And it was running on FRST OFAB with a custom chip. Went like buggery

What would you class as a good exhaust manifold?

crazycage

anything apart from a escort rst one.

Oranoco

Escort RS Turbo one does fine, Need to drill and tap the head to accept it but it works well. Mate is still on one at 380 at the wheels

crazycage

i know it does fine ,its the drilling and tapping that i dont like. seen loads of pulling studs out and always leaking oul out the threads ect .

theres a big gain to be had if your mate is still on one at that power for sure .

people run these to 360 so arnt bad, what other manifold is out there for 70?

rs-tuner

iTrader: (1)

Focus rs manifold maybe.

Oranoco

It's a preference thing then really, I know he's not had a problem with it and it's been like it for years. I doubt he'll change the set up as the 380 was recorded on low boost and when they tried to use high boost the engine tore itself free. It seems at that level the weak link is teh car its actually bolted in Does go insanely quick though

ive got a zetec turbo tall block for sale, made 397bhp/386lft for sale.

no manifolds tho as those sold.

stage 3 big valve head, piper custom bd10 grind cams, vernier pulleys, carrillo rods, wiseco pistons.

v man

i use the area 6 manifold

turbo sits over the gear box

excellent bit of kit but pricey

Fudgey

iTrader: (4)

but overkill for just 300bhp lol

mattseries2

iTrader: (1)

What sort of money are one of those?

mattseries2

iTrader: (1)

I see its for sale mate, ive got an engine lined up just wanted to know about manifolds etc, thanks anyway.

Fudgey

iTrader: (4)

open to offers lol

v man

true true but who stays at a power level

he will want more we all do

and if he got one then it will never need upgrading

v man

best asking ian from area 6 mate as i cant remember lol

but not just a straight swap

exhaust will need making for it as down pipe will be totally different

and air filter location needs some attention

but the best manifold by far imo

v man

the inlet from area 6 is also top top bit of kit

its a no loss maniflod and all the top speed zetec turbo's from over the years all use them

im not a sales man fro area 6 lol but the best stuff imo

mattseries2

iTrader: (1)

Yeh they do some really nice stuff! Your right i will want more power but not before a dry sump setup, which will be the next thing!

v man

yeh this oil pump buisness is worrying

ian told me its down to crank bounce ,
which is down to high revs

there is talks of harmonics and this and that

but you could have 1 million hourse power or 250

depending on how you drive it will depend on how long it all lasts

nothing is forever lasting in this game to be honest

mattseries2

iTrader: (1)

Yeh its worrying me too, heard so many horror stories. Touch wood at 300 i should be ok, ill be setting the rev limit to 7000 max. If i went for any more power i would dry sump it.

v man

yeh im changing to dry sump as im going of big to speeds

but the dry sump can be done anytime

like i say depends on how hard you drive it to how long it lasts ,
dry sump or not

MO' BENT RIMS

ok lads now i no i will probably get criticism but why spend loads and loads when for 300bhp u dont.

my zetec turbo is running a proven 300plus bhp ,

my spec SKIMMED PISTONS WITH STANDARD RODS
FOCUS RS HEADGASKET
T4 TURBO
ROVER INLET
750CC INJECTORS [ TOO MUCH FUEL SO RICH BUT GOOD FOR FLAMES ON REDLINE!!!!]
COSSIE COMPETITION RACE PUMP
FUEL REGULATOR RUNNING MAX PRESSURE BECUASE I USE IT FOR A38TOP SPEED RUNS AND DONT WANT IT LEAN [ this is wrong but i do it anyway]
individual coil pack on plus conversion

THIS CAR gets started in the morning for work and then after work i drive it for hours beating it having fun and the car has been perfect on track days its NEVER let me down apart from a fuel hose coming off the fuel reg its been PERFECT! people just dont believe my spec engine would do this much power but it is and been like this for months now ... at 250bhp it was like this for 4 years and now at 300plus bhp its still perfect

MO' BENT RIMS

just to add 4 of my mates copied my spec and theres is perfect! i got the idea after seeing SEVS fiesta xr2 with the same engine spec as mine do 325bhp and he drives it like its stolen!!! all this time and its still alive tearing up the roads and doing track days...only thing on his is a external wastegate set up

MO' BENT RIMS

i forgot to mention is also has double valve springs

Dennis_Wiseman

iTrader: (1)

How much did you shave off the pistons ?

crumpet

mo sev hardly uses his xr2,. i saw it 2 weeks ago in cannock, he doesnt really go down the a38 much either lol but thats still running the same spec as yours, if you go down the a38 i take it youl know aheel with the zaf and his mate with the 700bhp evo 3

QplateRST!

You could use a standard erst manifold and have a zetec flange welded on it I ran my fiesta like this at first and it was faultless I only changed it due to going external wastegate a mate of my still has the manifold he might sell it if your intersted?

SiZT

I sure as hell hope they're not Blacktop pistons

XRT_si

iTrader: (2)

Agreed, no need for dry sump at that level IMO.

Do NOT use an Escort RS turbo manifold unless it's fitted WITHOUT drilling and tapping. Whether that be by using an adaptor plate, or welding on a new flange. They piss oil and work loose. Anyone that did an early ZT conversion this way knows it was shit after a little while (me included )

It's a combination of big power and revs. Revs alone do not kill them, they can rev past 8500rpm with no failures when N/A. It's the cylinder pressures which seem to wipe them out but a low power (300bhp ish) Zetec turbo will never see a pump failure IMO. No matter hopw hard it's driven. I gave mine DEATH for 2 years and 10,000 miles with no problems what so ever.

Proper double spring conversion or uprated singles?

nevsrevs

i dont know wat to think about pump failure? is it people skimping and not buying new pumps when they do there builds?

MO' BENT RIMS

crumpet yes i no him i live just 5 min away from him mate

johnny99

Rods or rod bolts for 300 ?

John

mattseries2

iTrader: (1)

Was yours a silvertop or blacktop mate?

What exhaust manifold did you run?

XRT_si

iTrader: (2)

It's the new patent parts that are the problem, it's been suggested to use a Zetec pump that's done a 40k miles or so.

Rod bolts need doing ASAP for any boost/revswhat so ever. Rods have been known to do 330bhp a few times but they're at the absolute limit, so up to you.

Mine was a Silvertop and used an Escort RS turbo manifold that was drilled and tapped, hence why I know it's shit to do and didn't use one the second time!

creator

I had a erst exhaust manifold on my old zt (was on engine when i got it) and it never gave any problems after around 10,000 miles

crumpet

mo you from walsall then?
