Hi, basically we purchased a MK Indy kit car last year, its running a 2.1 pinto with bike carbs, my question is, what sort of power can i expect from the spec below? is the pinto really the engine for the job due to its own weight also or is there better alternatives i could use within the same budget as rebuilding or upgrading the pinto if needed?

spec i was told is:
2.1 using v6 pistons
standrad rods and bolts
injection head
cam unknown with adjustable pulley
r1 bike carbs jetted for 2.1
then the satinless exhaust

It doesnt go to bad as the car is light, but it does tend to run out of puff up the rev range, it feels like the car is to retarted up top even slightly lean, any info will be much appreciated on where to go next, i personally was thinking zetec but then its a case of different flywheels and starters etc where as with the pinto the ancillaries are mostly there, Paul.

id say with that spec its 150/160ish bhp

So say its 150bhp, what is the way forward on getting the best from a pinto, i could use a zetec but i personally think (i may be wrong) that due to all the ancillaries etc that are already there for the pinto it would be easier and the end results would be similar on the 2 engines in regards to power n/a, pinto possibly more torque due to being 2.1?

I'd say it's knocking on the door of 150ish.

Ask on Oldskoolford forum or pinotpower for a more definitive answer though.

Unless the dizzy has been adjusted you're wasting your time.
These need huge amounts of advance, your best bet is to get a BOSCH dizzy with the removable windows in the dizzy body side, use a older dizzy and convert it for around £30 to electronic ignition, then do some dizzy modding.
Set the base/static timing to std and try it, then advance 2 degrees at a time till it is nice low down to about 1/3 throttle, record this figure, now you will no doubt find it pinking under load, using a screwdriver through the dizzy body window(small caps that pop out) bend the stops so the weights can move so far out under centrifugal force, this will limit total advance.
It's a pita but well worth the time to do it, a sit makes the best of both worlds, this is how I've always done it.
You'll be amazed with the drive ability increase lower fuel consumption, and power, listen for the exhaust note changing with different amounts of ignition, and you'll son get the hang of it.
V6 pistons usually result in around 2086cc from memory(been years!!).
A really good way to extra performance is a lightened flywheel as pinto ones are very heavy, as are cossie ones mine was 8.9KG(std 2wd) lightening/skimming for £40 or so had this to 6.6KG, a very useful increase for the money, same weight(6.6) as a 1.4 saxo flywheel by the way for comparison.
Without a shadow of doubt the best mod for the money in alight weight kit car that doesn't need inertia/energy stored in a flywheel.
The injection head is almost identical to std, it just has a slightly better as std port, and a boss/lump in the top of the throat but takes less work to port as some is already done, the mad professor Roland Hayes of HT racing is a genius with these heads.
