The intake plumbing needs to be radically modified to get those rpm figures i guess. But still: do we have any sources for lighter/stronger valves/rockers/pushrods for our alfas? I haven't found anything on the net so far. Only IAP's "performance" valve springs.

thanks for your thoughts on the subject. I can agree that the 3.0L is the best option when looking at maximum attainable power. But with so many GTV3.0L going about i like to have something a little different. A Gleich replica floats my boat in that respect. For the serious power of the hot Gleich m...

2.8L conversion

I have a set of pistons and liners for a 2.8L conversion for the 2.5 V6 in the garage, The set has never been used and is actually from the times when Dieter Gleich made 2.8L conversions in the '80ies. I have been tempted by this conversion for some time, but due to the required block machining i pu...

I was not aware that the new tensioner was intended for a different type of belt. Guess that explains the poor performance of that particular tensioner on the older engines. Barry; i think it was you who had the good rule of thumb for tensioning the belt with the modified old tensioner in another th...

Mechanical type tensioner failed on me on monday. Luckily all valves are good. I reinstalled the plugged hydraulic type as per advise :roll: I started the engine up and let it heat up to operating temp. Now the belt is very firm. I think it's maybe too much thension. What should be the install tensi...

I started a thread on this topic a few months ago. Turns out there are many different opinions on this subject. You have the three possibilities as you mention. Hydraulic, mechanical and the plugged hydraulic type. I had the same experience as you with the hydraulic tensioner. Leaking even after fre...

If car is rusted it is wise to never use the official side jack points. They may easily disappear into the cabin.. Better to jack your car on the two frame beams underneath, and put the jackstands under those as well. Also, you have a single jackpoint in the front, that will allow you to raise both ...

Are the high-performance springs sold by IAP the same as the Arricambi type ?

Replies: 13

Liners are not pressed into the block, they are only mounted with a fine tolerance slide fit. So they normally slide right out with light hand force. But sometimes they can get warped, i guess due to overheating, causing them to get stuck. On my engine i had one such troublemaker. With a piece of wo...

i'd say : replace. These seals are taking a lot of punishment from the internal heat and are probably very crisp and aged by now. Good to get some fresh rubber in there.

Even if you leave them on the liner, just the dismantling / mounting of the liners may cause them to break and initiate a leak.

Hi Seb, Here's my thought on the subject: Acceleration times moment of inertia equals torque. For a given torque, if you reduce moment of inertia, the acceleration increases. By lightening the crank, you reduce moment of inertia. So you get better acceleration. But the same applies to deceleration. ...

Alfa Romeo and Ford should really have foreseen this issue when they designed their systems, and agreed on a standard wheel diameter and press fit tolerances once and for all :D

(but i am not so lucky; my EDIS wheel doesn't fit on the 75 hub)

There are people selling EDIS trigger wheels of different sizes from time to time on ebay. I think mounting depends on your crank pulley. On the Euro 2.5L pulley, i think the easiest would be to mount it on the outside, as it has a fairly flat face, with good space for bolting a wheel on with screws...

+ you need to run the Extra code in you ECU.
+There are some modifications needed on the printcard to get the right input/output for EDIS. Not to difficult, it is explained in -extra documentation.
