Tuning Making a 40mm Throttle Body

I now have a ported, skimmed and flowed head, with a fast road cam and a stainless 4-2-1 manifold .

And with those mods added to the sparky TB the effect is AMAZING

up to 3000rpm - grunty but similar to the stock SPI -- at 4000RPM it howls , picks up its skirts and f**ks off for the horizon.

At the recent kit car show people could not believe it was a Seicento engine :slayer::slayer:

Ive received 6 of these today for class 1b irish hillclimb cars. Thanks to Steve for making them for us. The quality of the bodies is superb, its a pity no one can actually see the work when fitted.... Now time to get my engine back together and see what this machne will go like. Ive a skimmed and ported head with a 866 cam which is shimmed and doweled, block tidied up for new rings, rods balanced and crank done up. Home made induction kit all ready to go with new gaskets, belt kit, clutch, thermostat etc. Exhaust will be decatted and reduced to a single ulter backbox. Have a mate working on a map to suit these mods, 4 chips to be tried and we'll pick the best and work on the other 3 to try and get closer. Will be happy woth over 70 hp but would love to see close to 80hp. Time will tell :)
 
Yes, I'm still doing the larger throttle bodies, I have a MPI one done and can do SPI and P75, send me a PM with which one your interested in.
