well my complete vx installation probably owes me about £4.5k, but remove the forged pistons, steel rods and laminated head gasket and it'd make
the same power safely for £3.5k. that's 220bhp, 170lb/ft.
And that was fully mapped and rolling roaded from a bare block, core plugs out, dipped, rebored and ground up total rebuild.

With that budget 200bhp should be too easy. I installed a 2.0 Zetec though the winter on TB's and freeflow tubular exhaust manifold. Much
quicker than the Pinto but not quick enough.
The head is coming off now and the new piper cams are in the office. Once done I will be close to 200bhp and all for around £1K.
With £2K to spare you could probably get that to 220bhp and £1K for stronger transmission.
A Bec has its uses but mainly as a track toy. Not too practical for road use. But with £3K I guess you could probably build a fairly special Bike
engine.
As I can testify from the recent Teesside trackday. Spend some of that money on good tyres as these will find you more time than lots of power that
you cannot get onto the road.
Summer's here!!!!

As Darren said you dont need silly power, to have a very quick seven. The cars are so light that you get to a point where you just cant put the power
down, no matter how good your tyres suspension are (ultima vs caterham 0-60)
Your volvo I would guess is probably just shy of 1400kg? (going based on our focus which will be about the same size) giving you 220bhp/tonne.
Most CEC sevens weigh in somewhere around 550-600kg. So to get the same power to weight you only need 132bhp. Already forgetting that you have weight
transfer on your side in a seven. If you want an idea how fast even a pinto engined car can be, have a word with mookaloid. 180bhp 2litre pinto will
see you at the 4.5-5 sec to 60 mark at a guess.
Then theres also the fact that the distance covered getting to 60 in a seven is less than the distance you will cover in your t5, so you will be going
faster for longer.
One thing you will have trouble with though is going much more than 120-130mph in a seven, they just arent aerodynamic!
If i had the money I would fit a duratec and the weber alpha throttle body kit. All bolt on, no internal mods and 240bhp out of the box. Whole set up
likely to cost in the region of £2k i would think.

you went out in the least powerfulest BEC
and even with that engine theres still hardly anything that will keep up
you now need to take a ride in a later 1 litre engine or busa etc and understand why CEC is the past £ for £

235hp XE should hit the mark!!!
Just make sure you have some decent tyres on it (yoko A048 or Toyos) or you'll never put any of it onto the tarmac!
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning
