You'd need to do this if you want to adjust the LCA on the 12V.

(Yes, I am kidding!! - these are from a TS engine. Customs thought they had something illicit inside them so had a quick look. Not mine by the way.)

Customs... Idiots... Bunch of glorified mall-cops - DRUNKEN WITH POWER (and now armed to the teeth - thanks to the single, most evil piece of legislation, ever passed in the United States)!

The "Patriot" Act now has even some 50-60 year-old fat, lazy, (and in many cases - DUMB as doughnuts) absolute slobs packin' Glocks! Wouldn't let me carry-on one of Ron's RSR shocks one time ("could be used as a weapon" was the assessment - had me go back outside to check it and I ended up missing AN INTERNATIONAL flight! Another time they pulled me from a flight over a ****ing alternator in my checked luggage!

Yes, I hate them! Morons. That entire over-reaction "protect the citizens/the government must think for the people" solution to it all is moronic - at best! Any way...

Speaking of RSRacing; I have been a very big proponent of Ron's setup. He must have 30-40,000 miles at the Ring alone on his own - and on other - suspensions by now (in about 40-50 different cars)! Heck, his CURRENT fleet of transaxle cars rented daily at the Ring is in excess of 35 or so Milano/75s and GTV6s, so I would have no room to question his expertise!

I run his full-race setup on the 24v 3.7 and his street-track setup on the 24v 3.0 Verde!

wow... did the x-ray show the hardened outside different to the softer core? leading them to think they were hollow? ****ing idiots

iv just ordered some of the csc headers. going to have them 'jet hot' coated here in australia, in a finish called sterling [google jet hot coatings if you interested].

im also going to do the megasquirt conversion. after reading more about it, i think i could pull it off without much trouble.

where can i buy clutches for the LSD? or do we have to use second hand ones?

going by steve rosser's walk through - Untitled Document - what megasquirt is he using? ms v1 i presume.

jazig.k · #19 (**permalink**) 11-07-2009, 03:05 PM

ok, going by the price of friction discs for the lsd, should i just buy 2 new ones and use the ones i already have? or 'suck it up' and but 4?

Hey JJ,

Try changing your name from Van Rensburg to Bin Rensburg, you might end up as a special guest in their special rooms. AMHIK. ^&%&^%!!!! I guess having the APEXi Big bore muffler in me bag also didn't help.

Anyway, Jazig, if you're looking for cams, you might wanna ask Richard Jemison. He knows cams. I wish I found out about his cams before I bought my CB. His cams make a stockish 12V head make power all the way to 7K rpm, idles smoother than the CB SM1, and I believe I got around 26 mpg (29 mpg Imperial) at 70-75 mph on the highway.

thanks evo,
im currently eyeing off a set of rjr's cams.

with the risk of going further off topic... i found this...
S14 Install - Phantom Grip - Get a Grip! Limited Slip Conversion Kits
a ebay find, had them listed for a couple alfas. i presume the springs between the plates to the work. wonder how long it last before wear becomes a issue.

edit:
not dial up friendly, and this page is what really shows best how it works. sorry.

Jazig,

Now is a good time to go shopping for items in the US, USD is cheap. There were some RJR cams in the classified section, very good price. I think it was the 570 cams. Good for a 3.0. But I would suggest getting your heads shave a wheel bit to bring up the compression to 10.5:1, maybe a slight port job.

jazig.k · #23 (**permalink**) 11-07-2009, 05:35 PM

how much off the head to bring it to 10.5:1? no valve interferance problems with the cams and a shave?

junglejustice · #24 (**permalink**) 11-08-2009, 09:08 AM

Guys, don't ever shave the heads to gain compression!

Standard practice as it may be, it is a very bad idea; if you ever over-heat and warp heads, or have some other head problem and have to resurface them, now you have a problem and no margin left!

I know that it is a quick fix to ge higher compression and you can do it with the block/sub still in the car, but don't - rather "lengthen" the rods (small-end off-set) and pocket the valve-releases in the pistons - much better (and reversible if you ever decided to go the other direction with the compression for forced-induction for example)!

JJ,

I would shave the heads if head availability is plentiful. Not sure about Australia, but in the US, people are offering a pair of 3L heads for $300 (some even "beg" others to take it off their hands). And if you take good care of the car, it will be a long time before you overheat the engine.

I personally would buy forged pistons. I did, JE forged pistons for my 12V, very happy with them and not bother with rod modification or shaving the head, but I have to admit that this is a very cost effective mod. Unless of course heads are not easy to comeby and the weather is usually hot or the cooling system is marginal, then shaving the heads may not be such good idea.

Greg Gordon · #26 (**permalink**) 11-08-2009, 02:05 PM

I don't like shaving the heads either. It throws off the cam timing, makes the head thinner, and it's not reverseable. It's starting to get tougher to find heads, the older the car gets, the tougher it is. Try finding a good unmolested head for a 1600. They are out there, but few and far between.

JE pistons are a better way to go. Rebore your existing liners and the extra cost isn't too bad, and it's far outweighed by the benefits.

It's not the 300, or 600 bucks for a set of replacement heads that I am worried about; it's the 1,500 or 2K dollars that one might have invested in the porting/flow-bench/matching of runners/custom valves & seats & valve-angles etc and now you have the labour to re-shim the existing cams into the new heads - on and on!

In any event, the stock rods and stock pistons are good enough for 7000 revs all day long with the compression modified to 10.5:1 or 10.7:1 and premium pump-gas (as long as your fuel-maps are good and the timing is not too slow or too fast...)

Forced induction, higher revs, or higher compression than that - the Venolias, JEs and Ross jobbies are a better option!

1 Ozzie dollar is .92 USD....

Why haven't I seen more of you over here for vacation!!??

jazig.k · #29 (**permalink**) 11-09-2009, 01:01 AM

right-o, iv been convinced not to shave the heads for compresion ill just get them resurfaced. we have hot summers, where the cooling is stressed out enough as is. and 3lt's are hard enough to find, before worring about how much some new heads will cost me! by numbers that iv been told, only a total of 84 3lt 75's were brought to australia, and 4 special imported ones.

so, iv just asked a well know and respected place about head work, and decided [forcefully] its out of my budget for now. damn it. i dont think i should take it on myself, even with the linked walkthrough.
well the matching of the headers i can do myself, no? and the rest of the heads are in mint condition.
should i just stick to a 's' cam or go something a little more lively? remember im going with megasquirt too.

more aussies to america? we're having financial issues here too, so i guess thats the reason. interests rates are the big problem atm, while i dont pay much attention [i dont have a morgage, im 20] we're getting raped by the banks last i remember. the dollar is great for buying car parts though! shame american postage costs are a killer, but thats still usually countered by the good dollar.

I remember just 6 months ago I was looking into importing goodies from Australia when it was like .68 AUD to USD, but now...I think this could be a major opportunity for you guys to grab as much as you can...unless we keep slipping further

Anyways, the cost of the cam gears is something to consider when deciding to shave the head as well. Also know that, the more duration off the seat your cams are, the more you are going to need an increase in compression. So if you decide to go with some 10.5:1 or higher pistons, you should get hot cams. If you just want to install some QV pistons (10:1) then I think S cams or slightly warmer would be good.

9.5:1 and hot cams will be pretty regrettable I would think. Look at alfagtv6.com/bb for setup tips for MS and Alfa V6 if you haven't already.

Don't worry too much about porting of the heads, a friend showed me some diagrams from JimK's V6 book and it doesn't seem like there was a need to go wild with the porting, unlike the Alfa 4 cylinder engines. If you can, look up 75evo's specs...might be a similar direction that you're going in.
