This may have been asked before but I cannot find anything and i'm intrigued to know a few things.

1) Why does it cost so much to get a FRS upto or above 300-350bhp, when for less money you can build a good Blacktop zetec turbo running 400+bhp?

2)Whats the difference between Blacktop Zetec oil pump FRS oil pump and ST170 oil pump?

3)I'm currently building a Zetec turbo sleeper, I have aquired alot of bits already- FRS inlet manifold, FRS exhaust manifold, FRS injector rail with injectors and tophat, FRS brembo front brakes and rear bear, Omex600 ecu.

Obviously I need an engine which is best ST170 bottom end with blacktop head or blacktop engine I'll be changing internals for either cosworth forged pistons and rods or set forged pistons/rods from PEC?

Cheers WES

 

I'm aiming for between 350-400 bhp I will be changing inlet and exhaust manifold/turbo housing for uprated once engine is run in, and I'm either going to use a T3 or T38 turbo

 

What do you class as big money to get a frs engine to 300-350bhp?

 

What I meant is I've read of people spending 2-3k on their FRS to get it too 350+bhp and the FRS is 212bhp to start!
Where as for 3k you can get 400+bhp from a zetec turbo build

 

3k for a 400+ bhp zetec turbo? are you joking?
Just the proper fuel system and management (or mapping) will be well over 1k.
Add forged pistons, connecting rods, uprated billet oil pump, correct turbo, exhaust plumbing,
intercooler and plumbing, etc........

Way higher than 3k.

 

just a remap will see the RS up to 300bhp

turbo , manifold , decat and it can bee up to 400 about £2500 worth

400bhp is the limit i think of the zetec in the RS , anymore than that and you will want to forge the bottem end (i know the pistons are already)

for a 400bhp zetec you are looking at jujst over 4k for the engine , then another £2.5k ontop of that to run the 400bhp the engines capable

 

If your going forged then stick with a black top, and remember you will be limited to turbo choice on a frs ex mani, good mani mind, and with the right gt25 you could get 320ish bhp.

 

Sounds good i dont want to run big psi and i'd be happy with 300bhp at wheels. I can get a frs rocker to sump for 1k needs rebuild is it wortg getting it or sticking with a blacktop? And whats difference in a blacktop head and a frs head? Cheers fellas

 

you should be able to get a good FRS engine complete for around £1500 quid....no rebuild required

 

Point me in the direction? I think some of the People that have been telling me wrong stuff about frs engine were miss informed or behind on times lol cheers people all help appreciated as i would really like to crack on with this build and have it complete by october latest

 

just get a standard blacktop, rip out rods and pistons, go to the states and get forged pistons and steel rods (go for bigger bore if you wish too) and build up the engine.
there you pretty much have a bottom end for a grand that wil take 400-500bhp comfortably.
then get a t34 or similar sized turbo and you're on the doorstep of 400bhp, management, injectors and fuel pump need to be capable though as does cooling systems.

can be done cheaply, can be done reliably, just got to get the right mix and what you want from it.

 

Someone else said to me about getting them from the states but where?

 

Ian Howell is the god of zetec turbos and I would use no other

Give him a shout mate and he wil be sure to tell what's what

 

Lee at Devil Developments builds a very good Zetec.

Done a few 500+ bhp cars now and I think the highest powered Zetec now? Or very shortly anyway!

 

Getting tuners to build a engine costs shit loads. I got quoted 6k for a full Zetec Turbo build. Sod that, i'll have a go at building it myself thank you very much lol

Do loads of research. Its not just a case of popping some forged pistons in, bolting up a turbo and away you go like you read on forums.

Most essential thing is finding a good engineer first.

 

Hi all,
Has anyone done a turbo build on ST170 with a decompression plate?

 

Yes lots of people, stick a blacktop head on

 

It's an old thread and Every one has there own view on this. And there are a lot of opinions.

Mine......

The st170 has the best flowing head of any of the zetec family with bigger inlet valves and ports. But although the vct is good for torque it's not something you will be short of with a blower.
It has better conrods with bigger rod bolts but they are not what you would classically call forged. Again the pistons have a bigger wrist pin.
The inlet ports are a little different to the blacktop really limiting the choice of off the shelf inlet manifolds.

The blacktop head does away with the hassle of vct but having less potential flow is not the limiting factor. Stock pistons rods and even oil pumps will give up before you run out of flow.

So for a budget build, and that's what a decomp' plate build is. The st bottom end with a blacktop top end and a 1.8mm hg gives a good budget option with a cr of around 9:1 giving great response and little lag with a tiny turbo.

Mine, (mock up)

Runs a little Subaru impreza Td04 and Focus Rs management. It's now changed as I've made it rwd for my kitcar.
Starting with around 220 bhp with a map only potential of around 275 ish. More than enough for me.

 

The engine's the easy bit.

This engine cost just under £4k to have built with forged pistons, rods, gas flowed head, knife edged lightened and balanced crank and rods, running a smidge over 400bhp

But then you have to think about the ancilliary stuff, engine management (running Omex 710) £1k, Injectors (Seimens 880cc) £3-400, manifold (Peron) £600, Turbo (Sabre Gt28 Hybrid) £1200, Clutch (Sachs 4 paddle) £600, exhaust, gearbox, pipework, A2A intercooler, better cooling, and so on and on.....

Then what about making it stop and go round things.....

The sky's the limit, this thing's had about £23k spent on it over the past 4 years to get to this point, and boy is it worth it!!

My point is, it ain't all about the engine, that's only a small part of building a half decent car

 

there are lots of threads on this here and the blacktop head and 1.8mm gasket seem to be the favoured 'cheap' way to do it. Bigdel is right though, the engine is only a small part of the actual cost. My budget build probably cost me a good £3-4k in reality and i'm in the engine machining trade with lots of jobs being free or at mates rates!

 

Hell yeah,

The budget built hybrid engine £800~900.
My sump an extra £500
Intercooler / radiator an extra £500
Fuel system an extra £500, lift pump, swirl pot, hp pump, all an fittings.
Turbo another £400, Low miles Subaru Td04 on a home made exhaust manifold custom braided oil and water feeds.
Inlet another £400, custom plenum, 440cc injectors, Mondeo v6 big throttle body

ecu and loom

exhaust system

engine ancillaries

The list goes on.
