engine to head

[arc]

not ganging up.. but what do you expect when tell to go and read posts properly and insult them? ("forgive me but your word means nothing to me.
") you've added on about using the panda inlet, because that aint what you said before

know of someone that used the punto 75 engine with the injectors in place still (so no holes) and used a panda carb setup and got quite a good result, however this was a kit car.

if the injectors are still in place like you've said then they must be using the punto75 inlet manifold..but now you've said they're using the panda manifold, which is it..deciede before you get arsey with me

Arc is quite right with what he is saying. 999, 1108 SPI, 1242 SPI heads are the same.

Seems odd to me. I stand corrected.

Thanks for clearing that up hun,

Leaving the injectors in was a presumption, My mistake, I will be more vigilant in future so to be clearer towards you.

I wasn't being arsey hun, lol, just that you misread what I typed hence what I said.

Anyway, blood is thicker than water.

Guess I am water then....

O/J (no not orange juice).

have a nice day.

well, no - just if you are going to tell someone they are wrong and to read what has been posted previous - make sure you know that what you've written is right in the first place. I've not misread anything.

arguing on the internet is silly though

Hi arc,

"Also, you did kinda contradict urself there

Not pretty much, they just are, it is a feature of them being part of the fire concept design.



yet


Quote:
however I am not convinced that the 55 and 60 heads are the same unless someone has some technical data to support this,



so which is it? they can't be completly (read, not pretty much) interchangeable if they're not the same can they."

This is where you misread a post.

and I clarified here;

"All fire heads are interchangable with all fire blocks - FACT - this is well known.

I have previously said that I am not convinced the 55 and 60 are the same as in the port sizing and the valve sizing because nobody has yet to prove this."

But your right this is silly.

i'm not on about that, i'm talking about the punto75 engine with the panda carb..

it's still silly, like

 

[waynegts]

so, i could use any engine out of a uno with a fire engine, use the head too, but keep the carb? it dont have injection see but want a bit more power,

would a bottom end off a uno 60s fit the head off an uno 45 fire engine?
cheers

From what I know, and what has been already posted, the answer is 'yes' if we're talking Uno 60 mk2 Uno.

However, if it is a mk1 Uno 60S then the answer is 'no'. The mk1 Uno 60 used the older ohc 1116cc engine which is totally different to the FIRE.

3 motorbike carbs? I presume you mean the busa throttle bodies on TBsei's sei that has throttle bodies that peak flow after 9k but it revs below this - yeah really clever (note to andrew ellsome - make them longer or swap them with variable length throttle bodes) :bang:

I've seen a racing Panda fitted with four motorcycle carburetors, and also with throttle bodies. Check Smokeme's website as he has some pics up on there of Pandas with different induction systems.

Smokeme has done one heck of a lot of work with FIRE engines and has some superb knowledge. See the power graphs for his turbo versions

Also worth bearing in mind, that from what I've read it's not just the valves and ports that are bigger on the Punto 75 head. The camshaft has greater lift/ duration, which puts the engine into a higher state of tune. Along with the MPI system, it gives a healthy increase over the SPI Punto 60 1242cc engine.

I'd like to drop in a 1242 Punto 75 engine into my mk1 Uno and run it on a carburetor, but it seems that the camshaft doesn't have the lobe to drive the fuel pump Then again, all I'd have to do is wire up an electric pump and I'll be away.

Anyone got a Punto 75 engine for sale?!!!!

Hang on a min, Peak Flow, eg: Max Volume Flow Rate? Theyre 42mm IIRC (Gets tuning book out)... Nah I cba disputing it, but small bore for big bore, Id say around the 38-40mm bore mark personally, based on the experiences of those that have 38mm and 40mm TB's. Much bigger and the flow into the head gets so slow it could cause bad idle and probably reduces the ram effect / takes it so high in the rev range its pointless

Variable length TB's? Dont you mean variable bore? All the length is gonna do is really mess things up, unless its all calculated and tuned....that will definately affect the ram-charging effect. And that is a good thing to keep!!

Oh. For the record on the head thing, I did run a 55 head on a 60 engine (Im currently running another 55 head as that one was fooked). The 75 is a better head. Looks to have slightly larger inlet ports (always a winner!). The valves are identical on the 55 and 60. I swapped a few over and their either too small a difference to measure (using something accurate - eg: vernier caliper), or they just bedded in nicely . Eitherway. They fitted

Do you have any more info on this Punto 75 engine with a Panda carburetor?

I was told that the 60 and 75 Punto engines don't have the lobe on the camshaft to drive the fuel pump. If they do then I could be in luck

My plan is to stick a 1242cc Punto 75 engine into my 1986 Uno but run it on a FIRE carburetor to save the hassle of swapping over to injection. As the 999cc only pushes out 45 bhp, getting close to 70 bhp (even with a small carburetor) is quite a hike and should make it more fun

Any information gratefully received!
