Ok so I was over in Derby today visiting a Panda nut looking for advice, with this in mind, has any-one ever fitted the Dizzy cap Ignition set-up to a 1242cc 8v (P75) engine???

with-out going into the why's and what for's I would like to know if its
A:- Been done before.
B:- If it has what to look out for.
C:- Any other advice.

A - been done in past, plug & play.

P75 head is 10 mm higher therefore intake manifold needs to be modified.

ps. I've weird feeling that there are more panda nuts in Derby, but i doubt that DragonMan was seeking for advice.

it was indeed DragonMan that I went to see but it was me looking for advice lol, he was very helpful.

Ok what I am doing is Bike Carbing a P75 Motor but needed a dizzy set-up for it as I am binning my cars ECU in prep for the carbs and the oldschool approach to my track car.

Yes I am well aware that 16v would give more power but as far as I am aware there has never been a Mk2 Sei 1242 8v Bike Carb done, I could be wrong.

does any-one have a handy link to a Panda that has been Bike Carbed (4 carbs) on a 1242 (P75 motor) or a similar F.I.R.E engine???

I went for a pair instead of a quartet due to the reduced capacity.

I have all the bits in my shed waiting for another Panda.

Thanks I think I actually looked at your video when I first thought about this. what sort of performance did you get off 2????

i'm after great power as its going to be a track car.

Torque mostly. The car would spin wheels in all gears on the road.

so 4 on a 1242 should make an animal lmao.

he is a mad man.. take it from me.. i have met the guy!

tell you something.. im looking forward to the end result of this.. i wanna see what this fire block can do >_<

Folk have got 170bhp out of them already (turbo).

Not a hope in hell of that from a n/a engine!

FordCosworth on here has a Cinq with a Turbo P75 in it and it is de-tuned to 185bhp, it ran 215bhp on the dyno but they turned it down as it was spinning the wheels on the dyno lol so the dessision was made it would be undrivable, its still spin happy at 185bhp.


all I am aiming for is 125bhp which I recon with enough time and effort should be possible. I ran 100bhp on my Mk1 Punto Sporting 16v with simple mods.


When I start building the engine in the next few months I will start a build thread but for now I just need to get it MOT'd lol

I think the real limitation -- Jason spinning wheels aside -- on the 8v is the head,. The formula 750 folk have done some really strange things with the engine, but you wonder how much of it (even if we could interrogate someone to find out what it was!) could be translated to a street car.

the other thing I thought about, didn't he have a GSR head fitted??? that would of freed it up some what.

I would stick with twins as the reason I chose the TDM ones was due to the capacity of the engine in relation to the fuel and air flow.

Small capacity quartets are a little all or nothing, high revving self destructing lumps that the banger boys wouldn't even consider.

A lot of people make the mistake of looking at F1 and such high profile motorsport for inspiration but you need to walk around the grass roots to see the true innovators. Ask anyone who has raced a Zetec round the dirt oval. 1600cc 16V or more for four anything less then it's Webbers or twin carb's.

Even the 2.0 Pinto stock car racers are apprehensive about quartets.

If you insist on a quartet of carb's on a 1242 16V engine I'd run a bank of ZXR400 or CBR400 carb's with the smallest jets possible and work your way up until you get the torque curve you want.

It'll mean a rolling road session with someone who knows his stuff. The only man for that job would be Dave Walker.

The two most important things to remember are...

1/ The angle the carb's sit on the bike needs to be replicated otherwise they will not work properly.

2/ The length of the inlet manifold should be proportionate to the the capacity. 10mm per 100cc for a twin set up 5mm per 100cc for 16V

Consult as many people as possible who have done this before. I have dabbled and never got to use the car properly due to the fuel pressure regulator not working correctly. The more people you ask the more you will know. As many opinions as possible before forming your own and acting upon them.

cheers for that, you have been a massive help, its an 8v I am doing it on so you recon twins off a 600 would be better than Quads of a 400???


My dad races in Autograss so I will ask a few of the blokes he knows but most of them are going to fuel injection now.


I really have my heart set on carbs now as they sound amazing.


so going off your comment, 10mm per 100cc, is that 100cc per cyliders run of carb or engine size, ie 1242cc for both carbs or 1242 / 2=621cc per twin carb or 310.5cc per cylinder

Engine capacity. The carb's and manifold for the FrankenFiat engine were 120mm long.



I have the whole set up in my shed if you're local and want to take a closer look.

P.S that's 120mm from the carb mounting to the head (the whole thing) and not 120mm from the head to the carb mounts (the yellow bit).

I'm in the Midlands near nottingham, how far is that from you??? A closer look and chat might be just what is needed here.

North West Norfolk, near King's Lynn so about seventy-ish miles.

Hmmmm maybe a bit far at the mo, I might arrange to pop over once I start the construction process in a few weeks.
