after reading about what u had wrote above it's got me a little worried as my frame is similar to xvalvers and mini Vlatko with very slight difference
is there a way of Strengthening the area around the toparm mount/tower..?..as u said this would be a very weak point taking speed/breaking force on this area
Mark. I have been asked many times before and no doubt will probably be asked many times more ........but the answer is NO .... I don't intend to sell the design or frames. It was a one off.... sorry.

I cannot remember too much about my proto mini subframe, but I guess it would be possible to build in some strength around the towers.... remember.... I was one of the first to go down this route ( mininut even earlier) so I guess with the number of homebuilds around now, it should be quite easy to have a look at an installed engine and frame and get an idea of clearance for bracing etc.

Maz(mininut) has been thrashing his car around for ages with modified mini subframe...... it hasn't broken yet !!!



Cheers FBM

Glad you have gone for the extra mount however I would have mounted it the other way around so that it is working in compression rather than constantly having a sheer force on it, these mounts are not designed to work that way. I would also add more gusset plates to all corners and more bracing to the turrets.
I have also found that a brace bar of some type is a good idea as the engine still moves a great deal even though it seems stiff on the mounts alone.

Well...after advice from the best I had to go for the 4th mount and now Im very glad especially after what happened to XEvalver...
But Im not sure what exactly you meant by saying "other way around"?
As for gusset plates...I was thinking exactly the same thing after all that braking and bending the subframe talk...


Now for my next issue...the bottom pulley!

I managed to take it of with chisel and hammer technique as these were the bolts I had to fight with




I will replace them with new ones and I was thinking of allen bolts!
What do you think? I dont know how hard are they tightened?

I would also like to machine my pulley but Im not sure how...some advice would be much appreciated...
If Im not mistaken that rubber works as a damper...can just trim it down same as the rest of it and can I just transfer the TDC marking on the "smaller" pulley?





Think I will go for poly V belt pulley in the future but this will have to work for now...

The fourth mount wants to be orientated the same way as the other three, ie stud pointing upwards. The rubber is then compressed between the steel plate parts of the mount rather then being sheared off the plates, if you see what I mean

Ohhh I see now
I decided to go this way just because my engine stood pretty firmly with only 3 mounts and this 4th mount now acts like stabilizer...took a peak at Allspeed frame too...

hey.

i replaced my pulley bolts with stainless M8 button head bolts and i've used a custom alloy single-v pulley (the kind that often comes up on ebay, although i got mine from a local XE specialist)

and i have two of those spark plug covers going spare, if you fancy, i'll pick out the cleanest one and send it off to you. i'd like an Opel one for the very reason you want the vauxhall one!

As Im trying to cut my expenses for start I would like to machine my pulley and then in future go for smaller alternator and poly v belt pulley...kinda hard to get these things here exactly when you need them, it takes a lot of internet search and lot of time to get it delivered I cant just go out and buy it like you guys can

As for button head bolts...I like the idea ...will do the search for them...I was thinking of plain allen bolts but Im not sure how hard they have to be tightened...wouldn want to have to chisel them again ...

Bout the plug cover...I think we have a deal
My adress in PM...waiting for yours!

Did my research again...dont want to bother you with too many questions ...and I see that lot of you XE drivers used Metro rad for cooling so I guess its sufficient!
Must say that Im very glad I kept it for over 5 years cause its not that easy to find one here...
And here it is!

i think most are using 16v corsa rads...but i think some have used metro rads aswell without any problems
i've just acuired a punto rad with the exspansion bottle on the side..also have MPI and original vauxhall...so i will see what i can get away with...

Well my initial thought was to machine the bigger pulley down cause I need the smaller one...
If I leave the bigger pulley, the alternator will be spinning faster than it should be?

all depends what size pully the alt has on it , but to be honest it does not matter.

I was thinking of leaving the standard Opel/Vauxhall one for start but in the future Ill be looking for a smaller one with poly V belt...

I think the smaller pulley is going down then
