hello from a pair of old duffers,the brother in law[smart alec]and I are rebuilding our locost,out goes 1300 crossflow and in rover 1.4 k mpi,so far so good.now we have all the bits from 1994 mpi car,we also have 1 set of 600 gixer tbs.he says if rover mems ran mpi,why not gixer tbs,[it's got 4 squirty bit similar says he] B*****s,says I things dont happen like that,this is 2007 not 1967.or do they ? any way many thanks for all the info we oldies have picked up from this site yes you can teach old dogs new tricks,ray+alec.

Learning new tricks every day

How to undo the hub nuts on a Sierra ? Blowtorch until the plastic threadlock oozes out (you're going to replace the nuts anyway, aren't you?)

Good luck and race you to the pensions counter.

Being "of a certain age" is no excuse for being a bit slack

Check out Chippy's photo archive, I hope I'm not upsetting him by pointing out he's older than the average builder but I've not been as impressed by anyone as much as I have by him. He's done everything in the "proper" locost style, from designing the chassis and building it, to bodywork and megasquirt !

I hope I'm half as open to new stuff when I'm his age

BTW I don't suppose you're Sarah Jane from cbeebies channel are you ? *dribbles*....

Will you gain much in the way of bhp by using bike TB's on the 1.4 ltr engine?

u have u2u

your user name is not always your own name,as we are old duffers we got one of the kids to set it up:ray+alec.p,s need space more than horsepower,but would not say no to afew more gee gees,and tb,s look the watsits,with bells on.

Mems works mainly on the MAP sensor signal (manifold absolute pressure), on the standard Rover manifold this signal is fairly well damped by the manifold volume with seperate throttle bodies even if you tee all four together the pressure signal is going to have much higher amplitude pulses than he Rover setup.

In short I don't know it might work it might not.

If going to throttlebodies I would go for Megasquirt, however other easier tweaks are around for the K.
If you can find one the early Mpi 1.4 used a cast alloy inlet manifold which is worth a few horsepower at 1994 your engine might already have one, if it has the downside is it will have a much less sporty cam profile than the later K engines, easy to fix with a cam transplant.

Another simple mod is to raise the fuel pressure by "adjusting" the fuel pressure regulator in a vice.

Thanks for that bt,ray.
