the mounts for the na 1g and turbo 1g are different..
youll find that there are 6 factory holes not 4.
the middle holes remain common, but depending on what car it goes into, the mounts will either bolt to the 2 more forward or 2 more rearward holes.
my memory of what exactly we did is a little sketchy as the conversion was done before my bro's birthday.. and went something like this..
Sat 10am- start working on conversion 11am- engine out, start drinking. 11-12- fit all pedals, clutch master, lines etc. 12- stop for lunch, have many a beer 1-3 swap gearbox over from NA to turbo motors have some beers 3-4 try get motor in, go first time- drink 4-5 get motor in, but sitting in wrong position. drink 5-6 swap mounts over.. modify mounts with grinder..while drinking several beers. 6-7 sump fouling on x-member.. just get drunk
Sun 7am- no sleep, still drunk..swap sumps 8am-10am- put motor in while recovering, having breakfast etc... 11am- motor in. start drinking again.. the rest is a blur..
