Engine upgrade

This is the first blog I have ever done so it probably be a bit of a mess. The second hand engine was in excellent condition and I could have just dropped it in. Because the standard pistons are a bit weak and I intend to use it for track days I decided to upgrade the pistons on a budget! . I sourced a second hand set of VVC 160 pistons with new rings from DVA along with gaskets etc. This soon adds up!, the cylinder head was standard but exhaust valve were shot, full of pits. Oily hands came to the rescue with a set of second hand refaced valves. I have a Janspeed cylinder head with solid tappets but I can't use it unless I fit solid tappet cams, bugger, so I cleaned up the combustion camber, and valve throats on the standard head and fitted a set of second hand VVC tappets with Super sport cams. One thing I hadn't considered on my 1.4 was injectors so managed to get a set of higher capacity blue VVC injectors and a set of cream injectors. The new engine is like chalk and cheese compared to my 1.4 I think the throttle bodies and exhaust were just too large and I wasn't getting the best from it. I just need to get it on to a rolling road it should be good for about 150 bhp ?

Great blog Phil, thanks for sharing. Great pics too. Hoping for a fine spell if weather so you get chance to enjoy!!

Thanks Paul

I will try to make it to the next meeting if I'm not working. I have been out today, the roads are terrible! never seen as many holes,gravel and mud.

Was out in the 7 today (did the long way to work and back) and the road back (coming across from Croft way towards Yarm), which is a lovely road, was a mess. Dirty, mega bumpy and full of holes. Never noticed it so bad, but actually wasn't a pleasant experience today as so bad. Car was bucking about everywhere

 After being humiliated by an ancient Westfield at Croft 

I am considering my options, this car blew the doors off mine down the straights,cost less than half my car! I can pick up a Megabusa for less than the cost my car standard and I have thrown a load of cash at it. Ok they are not as nice but they seem to handle just as well and are diy rebuild friendly. I am not keen on the looks but I have seen one for sale with a Kawasaki 1400 engine and it's a bargain. I realise this is probably not the correct place to ask but has anyone had one, the Megabusa seems to get rated highly. Much as I would like a high performance Caterham I can't afford the premium,and my efforts to build a decent high performance 1.8 seemed to have failed miserably.

Look at the state of the work on that car,the inlet manifold did not match the head, we are talking 1/4 inch steps in the wrong direction, carbs miles out! water leaks from most hoses, terrible brakes drums on rear and a live axle. If this car was set properly and had some time and small amount of cash spent on it. I would get lapped quite quickly! 

I am looking to have one last go at getting some decent power out of a K series but I may throw the towel in if the expense starts to ramp up too much

Oh forget after all that effort I made around 145/150 bhp at the flywheel ,quite pleased with that but after two rolling road days cam swings, compression tests, different size airhorns, air box on and off ,it peaked at 6000 rpm eek and it completely gone by 6500.

One Toyota engine dragged out of a scrap car,cams thrown in, wrong inlet manifold, oversize carbs wrongly jetted and a 175 bhp at over 7500 and still climbing! Grumpy manifold air leaks, most of air filters inside carbs and inlet manifold etc, etc  

New cylinder head lets see if I can manage 100 bhp per liter ( optimistic )
