Depending how different the balance is with the swap I think this link should be a good starting point to be refined on.

Also on a side note, does anyone have tips on how to get the oil pan core off? I got all the bolts out except for the one I assume is under the front seal. I have the front seal unbolted but I can't seam to pry the plate off without damaging it. I'm pretty sure its stuck on the crank seal. Is there any way of removing that plate without bending it?

Thanks

Destroy the plate, it’s a cheap replacement and is the “front crank seal” so it should be replaced anyway.

Thanks! We have a relationship with a race team that should be able to help us. They do lots of carbon work and have run multiple Daytona Prototype programs. Regardless, the more resources the better!

It's much easier than trying to attach the aluminum Lokar end piece to the pedal linkage, IMO (I tried it a couple times and ripped my hair out in frustration before I figured out that the 944 pieces could be used).
Thanks Alan. Do you guys also have the details on the power steering fittings you used? Did you reuse any of the factory lines?

Curious how you'll be addressing the front axle. It is archaic and certainly not designed to be used with 600hp and downforce. Porsche redesigned the front axle for the GTRs using 935 parts.

Hey all, I've searched back through the thread and checked out the parts spreadsheet.
Please could anyone help me double-check that this parts list is the most accurate and up to date before I order?

(this'll be for a turbo build)

06A905115D ignition coils (audi oem)
900143 Pontiac solstice slave cylinder & bearing - if I'm looking for an OEM Solstice cylinder, should I get the base or GXP version? they have different part numbers from pontiac. Do I need the separate pilot bearing also?
1J0422152G 1.8T power steering pump (vw/audi oem)
021133064A throttle body (VW oem)

thanks for any help.

  • Coils are Audi/VW 1.8T coils, that is the correct part number for OE. Mike describes them in this video -
  • GM part number for the slave cylinder is 24234308 or 24249824. As far as I know you need the GXP version. If you buy the Boost Brothers Garage bell housing they will include a pilot bearing with their adapter. Good price here - https://www.ebay.com/itm/2007-2010-S...M/230627242695
  • Adapter for slave cylinder to allow an AN line to be used can be bought here - https://www.ebay.com/itm/GM-LS-LSX-T...P/352395034436
  • The power steering pump was used on a bunch of different models and engines so it has a lot of OE part numbers, 1J0422152G is one of them. Seems most start with 1J042215xxx. Not sure what the differences are or why there are so many different numbers. I bought one that fits a 1.9L diesel and it fits fine.... 1J0422154A but also 1J0422154E, 1J0422154H, 1J0422154HV, etc.
  • 021133064A is correct for cable driven throttle body, from early VR6 models. If you want drive-by-wire, stock 07K and there are some others that fit as well I think, search this thread. Not sure if the Performance Electronics kit that Boost Brothers Garage sells will support DBW and you would need a custom pedal.
