Mike's question (Re: WTB: Urgent - twinspark axles and cv's)

[Darryl]

Replying to http://www.alfaclubvic.org.au/forum/index.php?topic=10285.msg63461#msg63461 request for comment (Mike, if you feel like you are talking to yourself on the for sale/wanted area that's because nobody other than thread starter can post a reply there anymore).

Mike asked: Can anyone comment on whether Alfa 75 3ltr cv's will bolt up to twinspark stub axles?  I at least have a set of these.

No - M10 fine on 3ltr, M8 fine on twinspark.

You can swap the output shafts if you have a 3L box (TS and 3L output shafts are same size - not so for non LSD 4 cylinder). I suspect GTV6 and 75 2.5L diff output shafts are same size as the 3L and TS as well (but don't quote me on that - just thinking those boxes are a dime a dozen so could find out cheaply and quickly locally to confirm or otherwise?).

Happy to be corrected on any of those.... And no, I don't have any of the bits I'm suggesting spare....

Exactly what Darryl said. Bolts are larger on a v6z you will have to change the axels from the inside of the diff. That's if the 4cyl and v6 have the same amount of splines.

That's if the 4cyl and v6 have the same amount of splines.

4 cylinder *non LSD* (ie everything but twinspark) has smaller shaft/spline diameter on diff output shafts and *will not fit* a V6 diff. Twinspark and 3L shaft/spline is same, twinspark is the only version to fit the LSD that is M8x1 on the flanges. That much I know first hand. I'm not sure about the V6 2.5L, non LSD - I've heard different stories and haven't tried...

I have a set from a 90, I tried to message but it always failed,

Can the forum change the option so we can reply to these ads as its so frustrating

[Mike]

Thanks Darryl and guys.

Firstly, I missed out a number in my mobile number.....fixed it in the add but it is 0488091723.

If you have a good set of Alfa 90 stub axles that would be handy, re-pm me a price and we can sort it.

OK, well I have a full 3ltr rear end and obviously the diff is stronger.  Ihave been keen to stay away from the 3ltr as much as possible just becuase of the taller diff, but the axles and cv's are massive which would be nice and the diff is much stronger with the 4 sun gears as pposed to 2 in the twinspark.  For those that do not know, I smashed my cv at the drag strip....dig run 108mpr though on first run which was nice...30 deg day also.

I am teetering on the edge of doing a corvette import to put the c6 transaxle in but that is a much more expensive and longer term option.  So in the mean time I need to replace cv's and go frmo there.  I doubt I can buy new cv's....I did search but it came up negative.

I always take feedback into consideration, but it's unlikely in this case.

You should be glad - you might have got some interesting replies to your ad for your 90 'race car' that does sub 1.50s on the long track at Winton.  Not a bad deal for over $1k - does it include the v8 supercar wing?

[Mike]

Evan I think the guy has a point, surely we are all big enough to take a little crap on our for sale adds for the benefit of being able to converse.  If one person has a question about your add, many will also, at least the lap time could be cleared up quickly!  I have actually noted that for sale adds seem to have dropped off, there seems to be no where near the traffic there has been, maybe it is for other reasons, or perhaps I am imagining it.

Bring back comments on adds I say.

Cheers

Mike(or anyone else that might be able to answer), on the 3.0L diff install into the GT, are you using the 3.0L front section of the transaxle? clutch, slave etc? what system are you planning to use for shift linkages?

My question.. does the 2.0L gearbox housing accept the 3.0L diff housing? I want the taller diff, longer gearset(and LSD), but want to keep the 2.0L clutch, slave, flywheel etc.. Would need the TS output shafts too or frankenstein driveshafts..

Do-able (I have this setup though the gearbox internals are a bit non-stock so ratios aren't as tall as std 3L). I ended up with a set of early Alfetta driveshafts which are shorter and have the "cottonreel" between the disk brakes and the CV. These have M10 holes so fit the 3L output flanges... The clutch bits swap over easily (given a 2L clutch and transaxle and a 3L next to it you will figure out pretty quickly which bits you need to swap). Selector shaft differences and/or fitting the isostatic mechanism and speedo sender differences are the  and are the other hassles (people have solved them in different ways - mine is 100% old school with the non-iso selector shaft fitted and the older speedo sender drive but its probably simpler to use an electronic converter box for the speedo).

[Storm_X]

What else did you damage besides the cv shaft ? Now I am regretting cutting mine in half with the angle grinder last year , if they are getting hard to find.

[Midda Samid]

interesting.. maybe we should start another thread rather than hijacking.. nah, Mike won't mind the discussion..

How much pain was in changing over the 3.0L to the old style shifter and old speedo drive? I'd like to keep the car working as designed. Through the whole process, is there machining required or are all parts available between the 2 boxes?

Forgot about the older style 2.0L output shafts being M10.. I changed mine over to M8's to get rid of that "cotton reel" about 5 years ago..I couldn't handle rounding off any more of those short head bolts that needed a special thin wall stahlwille spanner to get my discs off..

Pipedreams at the moment.. but sounds feasible.

My inbox from the last few years would indicate that apparently no we're not all big enough to take a little crap on our for sale ads.  More and bloodier complaints caused by that section than any other.

If you want to have a discussion, please feel free to post your parts request or parts for sale in one of the technical boards and post a cross-link in the for-sale board.  If you want to advertise your parts without someone telling you 'you're dreaming', then use the for-sale board.

[Mike]

Haha,

well ok, you probably got sick of that, and fari enough.  Shame we have to regulate everything to the lowest common denominator.  I prefer to target the offenders with a two strike and your out principle...retains forum funtionality and weeds out those who refuse to be social.

Cheers

You should not have to take any crap because you want to sell something, best move ever made, a move that would not be necessary if some people on this forum were a bit nicer and had basic respect, alot of for sale comments were just downgrading the item, not helpful if you are trying to sell something, someones price is their price, make them a offer then let them be 

[Storm_X]

Mike what exactly broke on your car ?
