What bhp do you reckon i'll make?
Based on this spec:
FRS inlet, rail, TB, injectors.
JE forged LC pistons and ST170 rods, Std head. Rebuilt t34 turbo, Walbro 255 fuel pump. Grp A cone filter. Large alloy IC from eBay. 74℃ thermostat. MS2 management, WB lambda. FRS exhaust manifold and upgraded FRS exhaust (3") through pipe.
Cheers people. Look forward to seeing the replies, FYI looking to run 15psi boost and it's a 2 litre black top.

Clarke isn't going to be too far off the mark, i'd say 280bhp at 15psi, the T34 is just into the efficiency zone, each psi should make approx 8-10bhp over a BAR.
it does depend on the mapping and safe limitations on the rods i'd say.

Yeah 280 is a nice sounding figure. Thanks for the info xr2wishy. Rods are the only thing I'm worrying about at the moment.
What does everyone think about oil pumps, guy at garage said mine had scored the inside housing where the gear runs flat against it (which it had) and said to replace it with a brand new ford pump.. thoughts, suggestions?

tbh id concentrate on the oil pump issue before worrying about what the rods will take. I think the oil pump is the Achilles heel. based on there experience ill wager that clarkia and xr2 wishy are within 5hp of there estimates.
Liking the sound of this. Defo need to find an oil pump, there are plent of eBay items for £65 -80, has anyone used one without it blowing up??
Sorted th fuel pump the other day, did anyone see the thread i put up of the install. I was expecting a bunch of people to tell me how dangerous it was.. like they tend to do.

I think its the revs that kill oil pumps. 7000 + and I think the harmonics through the crank causes the gear to shatter. im no zetec guru but im sure ive seen this somewhere.
from everything ive read on zetec turbos you will need valve springs for over 10/11psi
ive got a simular spec but im on stock rods, and a silver top 2.0 so I just ordered the devil developments valve springs just to be sure as my head is off at the min having frs gaskets fitted
my spec is
silver top
calibra 86mm pistons
zetec rods
arp rod bolts
t34.48 (might be fitting a over the gearbox manifold)
rs1800 inlet (might be going rover set up)
gotech pro ecu
devil developments springs
frs gaskets
grs fmic
i was hoping to run around 15psi but if it makes 280 bhp at that then i need to reduce it because of my rods being over their limit as im aiming for 250bhp

i hear people have different views on the st170 ones and 106gti ones but just thought stuff it and do it once
this talk of oil pump failures, i had a standard 68k pump on my setup and my limiter was set to 7400rpm and i was constantly bouncing off it.
forged/steel rods/pistons, arp mains/rod bolts etc.
i would recommend getting an original oil pump in good condition, strip and clean and go from there.

so got lots to do over the next few weeks, fit gotech, t34, new inlet, rebuild head and refit with new springs and frs gaskets, and i need to do the pedal mod

thats what i thought, so while my head was off i had to order a set and after days of research the devil development ones looked really good value, £150 for a silver top but a blacktop was £250 because it needs different retainers so £150 for my springs i thought was good.

Basically when he showed me it all i could see was marking on the housing from where the gear rotates against it, it looked like (and this is the best way i can describe it) the metal panels you get on burger van interior panels and burger van cheapy metal tables.. It could of been fine, but what do i know?Mate you just got a bargain there! Where the hell from?! Can i use the normal focus throttle cable linkage on the RS TB?
Nice spec list mate, rods will be fine for 300bhp though. it's your rev limit and boost pressure that will determine how quick those rods will turn into boomerangs.
Never heard of the st170 spring mod. I'm going for the 106gti ones with 2mm washers. Anyone heard about the 2mm washers going underneath to increase stiffness? is it a must?
Wish i had £250 to spung on springs but that is a rip off imo. Maybe after a while of driving in constant fear i will bite the bullet.. haha
Haven't got any oil pump pics because the guy at Specialised Engines didn't give me back the pump after showing me it was fucked.. hmmmmmm that was months ago now.

because im on a silver top it only cost me £150 for my springs

theres a full frs cams set up with springs, lifters and retainers complete on ebay at £145?
and the frst throttle bodie should work with the black top cable and vise versa
im going to try and use my rs1800 throttle bodie if i can otherwise try and find a frs throttle bodie

Yeah that's the safe limit imo, im going exactly the same, 15psi and 6750 soft 6800 hard rev limit. I'm gonna get a grp A filter, FRS TB, FRS rail (going to ask if he will chuck in sensors) for £90 What do you think?
Also seeing as everyone has been so helpful so far.. One more question, theres a 12000 mile std cat back FRS exhaust system come up. I want it but is it good for 300bhp mark?

More like 270/280 but only time will tell as you will lose the restrictive manifold and cat ect so might do
Yeh that inlet should be suitable, pretty much the same route as me

well.. FRS standard mani is staying for now.. but i think the decat pipe helps a shit load all by itself to be honest. It's not that i want the engine to push a solid 300bhp, i just want it to breathe well, no restrictions!
How long before I change the manifold for a tubular and a new cat back system haha..

The guy I spoke to said the same thing mark. Excited now
What do you reckon of this deal anyway - cat back FRS standard system with only 12k on it and stored in loft since, £100....

Bargain. Even if you end up not putting it on your car you could sell it on and make a good profit.
