Five Mistakes before you make them
1.Watch for salvage motors.
If you buy a motor from an accident-damaged car then ensure that the belt covers and pulleys are intact. If not it'll need a new crank pulley, or at worst, it could have bent the crankshaft.
2.Oil burning can be costly.
Check for oil burning, as this can be a problem, caused not by worn pistons rings but by glazed bores. Plateau honing is the only cure.
3.Guide problems can cause the valves to stick.
Some early engines suffered sticking valve guides, due to carbon deposits on the valve stems. Can be cured with a stronger valve spring and cap, or pistons contact will bend all 16 valves.
4.The cam tensioner is made from chocolate.
The standard cam tensioner pulley is plastic and can be breakdown in time, throwing the cambelt. You must replace with an uprated alloy version to be safe.
5.Pistons and rods are weak at high outputs.
If you're building an engine with race pistons, you must replace the con-rods, otherwise they'll break. Rods and pistons can be a weak point.
OIL SYSTEM
Uprated oil pump gear and relief valve
Price: £164.44 (the pair)
Where: www.sbdev.co.uk
Stock inner oil pump gears are sintered steel and can shatter at high revs and loadings. Combine that with a steel relief valve that can jam and it's a no-brainer to bin both items for uprated versions. SB Developments supplies a steel inner pump gear and a nylon oil relief valve, which cures any potential nasty episodes.
CAM TENSIONER
Uprated cam belt idlers
Price: £70.45
Where: www.sbdev.co.uk
THE vital starting point, even on a standard motor, as it gives total peace of mind at high revs on older engines. Why take the risk of throwing a cambelt and wreaking the engine when a fix is so cheap?
FIXED CAMBELT TENSIONER
Price: £58.47
Where: www.sbdev.co.uk
The standard automatic cambelt tensioner can be overwhelmed when the motor is revved hard. Happily, SBD supplies a fixed item, but then the cambelt tension is adjusted via the water pump.
ENGINE MANAGEMENT (ECU's)
MBE967 ECU
Price: £901.22 (including wiring loom)
Where: www.sbdev.co.uk
SB Developments recommends the MBE 967 ECU as it's easy to remap and they have lots of base programs to work from. Customers are supplied with software to allow them to remap the engine themselves for optimise performance. The price includes £431.22 for a bespoke wiring harness (it's expensive because it uses built in relays).
DTA E48 EXP
Price: contact DTA
Where: www.dtafast.co.uk
DTA's popular ECU's are also a good bet with the 1400 and 1600 XE engine. Affordable and with a good user interface, they shouldn't be overlooked.
UPRATED VALVE GEAR
Uprated valve springs, caps and platforms
Price: £186.40 per set
Where: www.sbdev.co.uk
As the standard valve gear is overwhelmed at higher valve lifts, it must be beefed up to accommodate more performance orientated camshafts. Uprated valve springs, caps and platforms are a well-proven, reliable cure.
CYLINDER HEAD
Best cylinder head
Price: Haggle
Where: Breaker's yard
Vauxhall has tweaked the cylinder head design several times over the past 13 years. The early C16XE head (casting number: 90472726) is a cracker as it uses much larger ports, whereas the later X14XE and X16XE use smaller and different shaped ports that peg the power back. The very latest head casting (number: 90400187) uses triangular inlet ports, which work a lot better, gaining up to 12bp.
Gas-flowed cylinder head
Price; £1527.50
Where: www.sbdev.co.uk
The standard cylinder head is very efficient and will flow up to 180bhp on 1600 and 150bhp on a 1400 before headwork is required. Beyond the point SB Developments can supply a flowed item with heavily modified exhaust ports (they weld them up then re-machine them to alter the shape), new valves and guides to gain up to 20bhp.
CARBS & THROTTLE BODIES
45mm Parallel throttle bodies
Price: £1111.55
Where: www.sbdev.co.uk
A better route if you can afford it, as they offer real driveability and performance gains over carburettors. These parallel 45mm versions include the fuel rail and inlet manifold, so all you need then is the ECU and wiring loom.
45mm Taper throttle bodies
Price: £932.84
Where: www.sbdev.co.uk
The Taper throttle bodies provide both a 10 bhp performance bonus and a packaging advantage over the parallels, so they're perfect for use on Corsas where space is restricted due to bulkhead and servo clearance problems. The price of £932.84 includes the fuel rail and inlet manifold. Expect a smooth, torquey 164bhp.
INDUCTION
Dblas plenum chamber or Mantzel Powerbox
Price: £717.38
Where: Regal Autosport/Courtenay Sport
Both the 1400 and 1600cc XE motors are deliberately restricted by one of the most torturous inlet manifolds ever designed, so this is THE starting point for any power upgrades. Happily, less restrictive versions are available from specialist Vauxhall tuners, adding a reliable 15-20bhp. Nice.
High performance inlet manifold for carbs and throttle bodies
Price: £134.00
Where: www.sbdev.co.uk
Does what it says on the tin. Allows fitment of either old-school carburettors or more driveable throttle bodies, which are the key to unlocking the latent power stored within this remarkable little lump.
PISTONS
Omega forged alloy pistons
Price: £454.96 per set (1600), £470.00 per set (1400)
Where: www.sbdev.co.uk
The standard piston will tolerate being pocketed to take higher valve lifts but at higher power outputs (up to 220bhp on the 1600) switching to forged pistons is a good idea for peace of mid. Omega's forged alloy items were developed in conjunction with SB Developments and include rings pins and circlips.
CON-RODS
Forged steel H-section con-rods
Price: £752.00 per set (1600), £789.60 per set (1400)
Where: www.sbdev.co.uk
These go hand in hand with the forged pistons and the combination makes for an unbreakable setup. How tough? Well, try over 240bhp at 10,000rpm on SB Developments' top sprint motor…..
EXHAUST MANIFOLD
FWD exhaust manifold
Price: £416.59
Where: www.sbdev.co.uk
This is a high-specification 2.5-inch diameter tubular exhaust manifold that requires a decent high-flow system to extract the best from it. Designed for Corsa/Nova applications, don't overlook it if you want to optimise your performance.
WET SUMP
Gated wet sump
Price: £446.50
Where: www.sbdev.co.uk
Front-wheel drive users subjecting the car to high G loading are recommended to fit a steel wet sump, which runs gates and baffles to eliminate surge issues. In addition SBD recommends fitting a re-circulating catch tank with a drain that returns any breathed oil back into the sump - a drawing is supplied by SBD, as it's a straightforward fabrication job.
Dry sump system
Price: £846.00
Where: www.sbdev.co.uk
For serious users it's recommended to fit a dry sump system in front-wheel drive applications. The basic systems cost £846.00 and it's also advisable if the engine is being fitted longitudinally into Caterham or Westfield application.
CAMSHAFTS
284/278 degree hi-lift cams
Price: £440.62
Where: www.sbdev.co.uk
These cams are ground from blanks and are good all-rounders, which can be used with either carbs or throttle bodies. With over 11mm of valve lift, the standard pistons will require pocketing (£150.40 per set) to avoid any potential contact, while the valve gear will require uprating to suit.
CRANKSHAFT
Billet stell crankshaft
Price: £1974.00
Where: www.sbdev.co.uk
Thankfully the stock crank is bomb-proof, coping with 220bhp on a 1600. As a good, cast steel unit it'll cope with 9000rpm for rallying and 9500rpm for sprints and hill climbs and is so well balanced it's often left untouched. The ultimate is a billet steel crank with smaller counterweights, that'll tolerate stratospheric rev (10,000 rpm plus) with no problems, but you'll need deep pockets!
ESSENTIAL KIT
Rear-wheel drive bellhousing
Price: £187.13
Allows for longitudinal fitments of the motor in Caterham/Westfield-style cars, mated to the popular Ford Sierra Type Nine five-speed gearbox.
Rear-wheel drive special clutch plate
Price: £121.02
Rear-wheel drive applications can utilise the original flywheel and clutch cover, but a revised drive plate is vital to mate up to the Type Nine Gearbox.
Smaller, lightweight alternator
Price: £223.94
Saves over two kilos compared to the stock generator and is smaller and easier to package as well.
Lightweight slotted steel flywheel
Price: £178.98
The standard flywheel weighs in at eight kilos, whereas this slotted lightweight flywheel for rear-wheel drive applications weighs just 3.8 kilos, including the ring gear, which will greatly improve throttle response.
Nova GTE
Price: From £250
Ideal recipient for a small block XE upgrade! Check out eBay or Autotrader for a suitable donor car. 1400 XE-engined Novas are currently pace-setting in a number of rally championships.

Ask Andy Hamilton, sure its something like every 3000 miles or something.
SBD failed to mention this to him (or something along those lines).
Anyone know where/how that car is coming along, or did he strip and sell it eventually?

Andy H only needed a rebuild because of the shite valve springs. I believe after fitting decent ones, the engine is good for 10-15k

Valve springs were supplied by SBD as far as I recall, hence why he was so angry about it. Small things supplied by SBD were the in-correct ones for his spec, and SBD were unwilling to fork out. (although this is just talk so could be BS).
Andy also runs mid 210's, so a lot smaller spec, no dry sump, only 4 injectors etc...
Thats why he went to Swindon Racing last I heard? Proper tuning company

Andy's has a dry sump  he got the new valve springs fitted IIRC to prolong the life of the engine

Your confusing me.
Andys engine went bang due to SBD supplying the wrong parts for the spec of his engine.
Last I knew, he was rebuilding it again but with Swindon Racing parts as SBD screwed him about.
His SBD spec wasn't dry sumped, unless he's gone to a a dry sump now? It wasn't a dry sump setup at this stage, still a wet sump.

Whilst on the breather topic, Pro-tech charge an absolute fortune for that set-up, which I believe is just a breather tank with a sump return (is that right?) If so can I take the medium sized cam-cover breather pipe to a catch tank then fit a drain pipe that tee's into the large diameter breather pipe (Crankcase-to-cam cover) 
Cheers

It's not for making a road car go fast. It's to make a race spec engine. In racing you have different classes and you have to adhere to the rules.
