Hi there. In about a month's time a friend of mine will be fitting a C20LET into a mk3 Astra GSi.
He will have two complete cars for the swap so everything will be available. We're going to swap the engine and 6 speed box into the Astra.
Before we start, are there any obvious problems we will encounter doing this swap? It seems like it will be a pretty straight forward swap to do but I thought I'd better ask before we start as we've got a restricted time zone to get this done (doing it whilst my parents are away for 3 weeks!).
Yeah its a DIY job to convert it. I had a kit that required some holes to be drilled and tapped but I believe you can now get a kit that is just a bolt-on-and-go. You'll need to use the F20 rear gearbox mount and shave a small nodule off the F28 casing to make it fit.
Getting a custom made exhaust is the only option but the fun lies in how you either get it to an exhaust place or how you entice an Animal round to make one for you .
