'Warming up' the Essex V6
Discussion
All
I'd appreciate some thoughts as to how to give the engine a few extra horses.
I've been trawling t'internet for ideas, and from what I've read so far it's a cam change and a dual/triple carb setup (on a new manifold). Good for 180+ horses ?
So, if you had £1,000 (parts only) to throw at what I believe to be a 138bhp standard engine, where would your money go ? Happy to source parts from ebay/second hand if I know what to find.
Note: I'm no engine builder, so all replies in plain english please !

40dfi carb, some headwork and a set of decent exhaust manifolds.I'd appreciate some thoughts as to how to give the engine a few extra horses.

many thanks for the replies.
Any chance you can elaborate on sources/prices. Eg. manifolds, head work
Also, what does the 40dfi carb offer on and above the 38dgas (?) already on the car ?
cheers

martin doesn't advocate the DF1 for a road car. Your 38 will be fine. Have a read of the tuning guide, 4 pages.

Piper do a 285 cam which is still ok on the road and doesn't cause valve clearance issues, and bore the chokes out in your dgas and it will be fine, infact some 3000m racers are doing around 270hp with a dgas believe it or not!! that with ported heads, manifolds and matched inlet manifold should give 185hp. Ric wood, JW Developments and Car Clinic are all specialists or there's always Burton Power. will be a bit over your budget to have all that done, but not much if you're doing the building?? 40 DFI5 expensive, not too clever on the road, and you'll double your fuel bill. A race carb really.

I know some of the cars running in HSCC are quoting this knd of figure from RW engines on a bored out DGas, but then I look at the exhaust systems and start to wonder how big the horses are? Seem to go well enough though!!

Mike, if you want some trick exhaust manifolds ...I have a couple of kits that need welding together...Adrian@
thanks Adrian; will give you a call on Monday.. and thanks for the other replies. Seems the 38dgas will do for now; had the car timing/carb set up this afternoon and bar a small petrol leak out of the rectangular box on the o/s front of the carb (now sorted) it was running fine.
Will take a look at the head work and exhaust manifolds, and also advised to get a steel timing chain.
Much appreciated.

Hi
Good bit. (£1,000)
I went for a Kent V63 cam, Weber 40, standard unleaded heads, steel cam gear and a Bosch Aldon distributor. New cam bearings and the block dipped to get all the cr*p out (and yes there was lots of sand/rust)
Cam bargain - second hand but from a known source with a full set of numbered cam followers.
Distributor bargain - second hand known source with coil leads etc (someone going to mapped fuel injection doing away with the distributor apart from the oil pump drive)
Weber - free !!
Heads and gear wheel - brand new ... most of the £1,000
Expensive bit.(Pistons £400 - rebore not telling !!)
I also went for +60 high compression pistons but got really stung by the engine shop who charged me double for the rebore as it was "two rebores" going out to maximum... destroyed the budget in one go.
I need a reliable 160bhp roadgoing tractable engine which hopefully I'll get.
Cheers
Chris
