The goal is to securely affix an 11" Moroso degree wheel to the end of the crankshaft, outboard of the crank pulley. I think our vehicles' axle hub nut is the same thread pitch as the M20 crankshaft end threads / end nut. I can use the deeper axle hub to thread on to the crank end, then use it...

New 1500 rebuild nearing completion and preparing for install. Question: The 1500 still in my X (which is to be uninstalled) has an aluminum blanking plate on the left lower front of the block, below the closest freeze plug. On my freshly rebuilt block, in that same location there are two...

I'm picking up a spare 1500 motor and am thinking of shaving the fire ring off to raise compression. This thread is NOT about whether it's a good idea or not because it makes the head too thin. Some folks have said they have done this with no ill effects. This is a spare motor and if it...

Can someone please tell me what this means and how to check/ fix the problem? The Ex. Gas Sensor dashboard light came on yesterday as I was pulling into the garage. The car seems to idle and run normally.

Hey all, I've been chasing things creating an uneven idle on my 1987 FI X1/9 and one thing i noticed is that charcoal canister has a port on the top that is not connected to anything. With the charcoal canister connected to the intake, there is a noticeable vacuum at the 90 degree elbow on the...

A couple of recent threads here have once again raised the questions of the various exhaust manifolds available for our engines. It seems info here is quite scattered and at times incorrect. Thought I would try to do some research and consolidate it into one thread. Special thanks to Andrew...

Hello guys, I tried to find on forum and on Google but without big success and maybe better way to get info from first hand... I want to ask about coolant / water connection for 128 or X1/9 when is used Tipo cylinder head, mean new type of head who dont have water outlet on right side and use 2...

Wow! I woke up this morning ready to change my side motor mount on my ‘78 X1/9 with a 1500CC and I’m lost!! I can remove the main bolt no problem, but how in the heck to you get to the remaining three??? The alternator belt and water pump look like they are in the way. Do I need to remove...

I've got some injectors I picked up some number of years ago that are labeled X1/9 and others that are labeled 124. The part numbers are different so I'm wondering if they injectors are car specific? The part numbers are: 4430293 (those are labeled X1/9) and 4393596 (those are labeled 124)...

Hey Folks, I sure would appreciate ideas and photos on creating a throttle linkage for the new twin Weber carbs I am installing on my X/19. I have a PBS manifold. The throttle rotation on the twin carbs is opposite of the stock carb. One suggestion I was given was to turn the carbs around on...

I have a couple questions regarding the Aux Air Valve. Currently I can only start my car with the throttle fully open (accelerator down to the floor) and then have to give it gas for about 2mins before it finally idles on it's own. Even then it's a rough idle, idle clears up after a 10min drive...

[Continued from Valve Adjustment Part Two-A: https://xwebforums.com/forum/index.php?threads/valve-adjustment-part-two-a.25497/#post-212035] Once you get the shim out, you'll see that it is just a metal disc (precision ground and hardened of course) approx. 33mm in diameter. Each shim would...

As many of you know, I have been trying to record info on all the cylinder heads I could find. This started as I was trying to source the ideal head for my engine build (Euro 1500 carb'ed). I quickly found out that there are so many head could possibly work, some good and some bad. Then there...

The fuel gauge has steadily moved downward over the years until recent fill ups only showed a 1/4 tank when in fact it was full. Suspecting a fluid-filled sender float, I pulled it and sure enough it was full. I looked it over with a magnifying glass while trying to see if there was a crack or...

I pulled the fuel tank from the '79 to clean it out after sitting for many years. When I removed the level sender mechanism I found the float bottle was half full of fuel. Then when I emptied out the tank another float bottle fell out, also full of fuel. Naturally they don't "float" well when...

Dr. Jeff has been asking for a description of my 1603 engine build, so I guess it is time to do it, The intent for this engine was to take advantage of the increased stroke and aim for maximum torque across a broad RPM range. I will use as many pictures as possible. Block: 14 bolt, drilled...

Deep in garage boxes found BMW e36 front suspension arm bush. Fits exactly into snail mount (~4mm thinner). Centre cylinder have to be used from old X19 bush. It fits too good, so I put a thin layer of wd40 can between bush and centre cylinder. In link part nr6...
