New guy with A310 in the US

Postby dallarax19 » Sun Dec 30, 2012 2:58 am

I am a "new" guy with an Alpine A310 but am in the US. I joined this site to correspond with other Alpine folks. To tell the actual truth it was to connect up with Martin Faulks concerning the PRV but I know there is a wealth of knowledge I can tap into with other members - Johnb. A bit of background, I am an in Automotive Engineering in specialty vehicles. I have a history with Renault and was my dads mechanic in the early 80s when he raced an R5 in the US Renault Cup.

I was 14yrs old when we got the car and raced it around the midwest US. My dad was a designer with AMC so we were connected with Renault Racing which had put their US shop in Belleville MI - about 35min from home. I saw many R5 Turbos including the IMSA GT car and was hooked. When I tuned 18 this Cup car was my car to drive to work and to the University. I was in tears when I had to trade the car for more reliable transportation. My wife and I have very fond memories of that car. It was my goal to get a R5 Turbo but they were out of reach. In 2000 I was feet away from a black R5T with my hand on my wallet but did not purchase it because I needed to fix a sick Audi A4. The next day I called on the car only to find it was sold to a guy in Greece. I was depressed, Fast forward to last year. My wife pointed out a couple years back it was about time I looked at getting a car to drive and have fun with. I got rid of my Cadillac and bought a Focus. I looked and looked for a R5 T but they jumped from $15k US to $43kUS overnight and out of my budget. In my investigation an Alpine popped up on Ebay. It was rough but probably good for me. The car did not sell but I contacted the seller and flew from MI to SC. It was a huge disappointment, the car was imported to Canada and driven through the winter and had many fixes by "European" mechanics. The car was in terrible shape, it would have required a body off restoration. The car had a totally cool R5T1 type of blue interior but it was too much for me at the time. I got a good idea of what was good and bad because the seller also had a car he had imported from Belgium 5mo earlier behind the project car. I could not take on another project car ( I have a Fiat Track car too) so I left for home empty handed and very disappointed.

A week later I get a call from the seller reluctantly telling me he would sell the Belgian car if I wanted it. I jumped at it, this was September 2011. I had seen only three Alpines, the first was a 110 I had seen at Mosport in Canada in 1984 or 1985, the second was a GTA in 1989 that AMC had sent to the company I worked for, I got to drive it for a very short distance, and the third was an A310 that I saw on the 401 near London Ontario on my way back from Montreal after the Canadian Grandprix in 1993. When my Alpine arrived it was a major milestone for me. It arrived on a rainy day but I got it fired up and put in the garage for the major inspection. This is what it looked like:

The next day I got a good look at what I got. The car idled fine and ran great at Wide Open Throttle but had no mid range. I got a carb rebuild kit and manuals from Simon. I rebuilt the carbs but still could not fix the mid range problem. I was searching the internet on information on the car and started to realize the seller had removed several parts before shipping the car. An unfortunate education for me. I bought the car thinking I could drive it with a bit of work while I was working on a major update for my track car. I did not expect it to require the attention it did. So I searched the internet for information and contacts and finally got connected with the US Alpine club.

I have not figured the US Alpine club out yet. I got a connected with a couple of guys but it seems to really be underground. The guys I contacted did seem to be interested in corresponding - very strange. I studied the dual carb set up on the 2.7ltr and could think of every problem it would create with the dual idle adjustment screws - I am still baffled at this. Anyway I contacted the president of the club and he recommended a mechanic in SC - like 15minutes from where I purchased the car, something is very odd at this point. Anyway I contacted the mechanic and struck a deal where I would send him my carbs and he would tune them to his car, I also sent my distributor too, incase the midrange advance was no good. To make a bad story short this "mechanic" did not do what we agreed and in the end I had to fork over $1400usf to get my carbs and distributor back. I never, never , ever have people do work for me but this was a case where I had another engine I was working on and just wanted to drive the Alpine. I am done with the US Alpine club.

So I got the car running and put about 50miles on it but the #5cylinder keeps fouling out with oil. I presume the gaskets have just given up but I still need to remove the engine to see how good is good. So I am now looking and PRV rebuild options. I also need to rebuild the trans, some issues there too, and need to restore the interior - just need fabric.

I look forward to colaborating with other a310 folks so look for additional posts by me.

By the way this is a different car but will give you an idea of my capabilities:

Hey Brian,
Welcome to the club... I feel for you and I know we have a few guys in our club with A310 that can assist you.. I only have a GTA Turbo and and A610 but if there is anything I can do to help, just IM...
I once sat in an X19 but found it too small for me, and I am not the tallest of guys, but you did a great job on it... and if you need parts for that shipping over, again I can help..
A great post and will be keen to see how you proceed.

Once again Welcome...
Vince..
The Saint.

Hi Brian,

Nice thread, obviously a lot of history there, especially with the 5’s. The T2s prices have rocket over here, and a bucket of rust sold for a crazy amount of money, always seem to be barn finds.. Your A310 looks good, and nice and original, so I think you have done well there. Did you see the A310 restoration link I posted on my main thread a few pages back I think, there was some good stuff on there worth looking at. There are some other good guys, Odd Fire on Aussie Frogs is running DCNFs and has a great deal of experience, and a couple of other chaps names escape me at the moment, will come back to be though.

As to the oiling improvements as mentioned on TurboBricks, the head castings were modified to hold an oil well around the cam, but I think you will have those anyway. There are changes to the rocker tubes that you can see photo of on my main thread, and if you pulled down the Volvo service manuals and look at the chain tension adjusters, they actually went through 3 revisions (2 shown in the Volvo manual, and a later one used on the 24V) that I know with the last being significantly different. The first two revisions with the same basic design, but the oil feed drilling for the chain spray was increased, and you can see that in the Volvo manual with part numbers. The chain guide rails went through numerous revisions however. There were changes to the metallurgy and compatibility of the rocker follower and the cam due to wear, and there were a number of suppliers for the cams, and this caused issue. The rocker arms were revised to what I believe is a tungsten alloy pad that is bonded to an alloy rocker arm, these are the ones you will want, and most likely you have the all steel rocker arms - heavy, otherwise the same geometry. You can mod the spray drilling in the follower to increase the oil spray to the lobe as well. The geometry is not a simple single rocker ratio number, since the cam sweeps an arc across the pad, and hence the ratio is continually changing quite significantly. Further note that the left and right banks need to be treated differently if done that way, as the relative direction of the cam rotation to the rocker follower is swapped, as the heads are not in fact handed, the casting core is the same simply rotated 180 deg (the external machine casting features are handed) i.e. the inlet rocker on the RH is the exhaust on the LH. This simple fact is often missed by many cam grinds (and grinders) that I know of. This was done for cost, and the same machine could be used for both, clever. An interesting side note is that you will see the exhaust ports face different ways left to right as it’s a curved port – note to the wise. Hence, I do not input a fixed ratio in simulation, but actually input measured valve lift against crank rotation, and set the rocker ratio as 1:1 in the software.

On a separate point you may want one of the moderators to move your thread to the Projects section so that your thread doesn’t get lost in the usual chit chat of Christmas pudding… Just a thought :wink:

Cheers,
Martin
