i've got two 84 944's and a 924S, along with an extra engine and transmission, all of which are project cars, that you could have for 2750. One of the cars is an automatic, but it has fuchs on it and it would be a good parts car or something to strip and sell the parts off of to makes some money back. The 924S has some body damage, but the manual 944 is perfect for a "get ready for the track" car. It needs some reassembly in the engine area, and one of the valves is "stuck" but that's what the extra engine is for!
Hope you find what you need and want!

Hi Tom,
My name is Tyler and I am currently converting an 84 944 (non turb) to a race car like you did with my college club. I was wondering if you did a balance shaft delete and if you did how did you go about that.
We currently have a "new" engine we plan on installing onto the car and we already have the entire engine stripped (balance shaft included). The thing that my club and I are struggling with is how to plug everything up and make it an official delete. We have considered purchasing a balance shat delete kit. I was just curious if you all went ahead with that or if you would, how you would do it.
Thanks!

Hi Tyler,
The very simplest way to "delete" the balance shaft is to leave the drive belt off. With this approach, you are removing the parasitic losses of spinning up the mass of the balance shafts. If you want to remove the balance shaft, to reduce weight, you will need to plug the oil supply ports at the bearing caps, using grub screws. Most folks would agree that the benefits of doing either are pretty marginal. Note that if you delete the balance shaft, there will be increased vibration in the engine. One area this can affect is the oil pickup tube, which may already be fatigued and the increased vibrations can push it over the edge, which will basically cause sudden oil pressure loss and will trash your engine instantly. Regardless, if you are rebuilding the engine, suck it up and buy a new Porsche OEM oil pickup tube. Do not think you can weld little brackets to the existing tube and do anything but add a heat affected zone that will become your new failure point.
Here is a link to the first of 5 articles on my website about rebuilding the early 944 engine.

Good luck

https://pcaclubracing.org/944-series/ Contains a 2023 schedule
So many of the 944 Spec links are dead-ends...
