I have been a member for a while and found some incredibly helpful info here. I have had a turbo'd MX5/miata for about a year and a half and am just getting into my hands dirty myself now so thought a good time to introduce myself.
I live in London, UK, and bought a white 1990 MX5 BBR turbo from a member of this forum at the end of '08 (not through the forum though).
Engine Size: 1.6
Engine mileage: 50000 (new engine received today as I $%$ed the 50000miler...)
Turbo: Garrett T25
TPS, o2 sensor
Diff: Torsen from a 1.8 fitted last summer after original went "bang, clang clang!!"
Steering Wheel: momo
Running approx 198 bhp, at least until I let the engine run dry of oil (thought I had a dodgy connection on the oil pressure gauge as it was sweeping wildly to the left - schoolboy error)
Putting a MK1 1994 1.6 auto engine into this, so far so good and intend to swap the camshafts out of the auto engine and replace with spares I have.
Only issue so far is the previous owner swapped engines too and seems to have plumbed the coolant return and the oil (feed or return?) into the block... The auto engine has studs where the holes are in the other engine... I assume that I need to drill a hole and tap a thread as the easiest option is to use the same format as the previous owner (so not redesign anything), but I would love confirmation of this, and (maybe stupid question) not sure the size of the current fittings so not sure size to tap so is there an easy way to identify the size I need form the fittings? - Maybe just measure would be simple but is it really that easy as the size must be accurate for a water-tight fit...?
By the way I have read a number of posts and the majority mention tapping into the oil pan and using oil pressure sender - is this better than direct into the block via those bosses/studs? As mentioned I wanted to keep it the same as the previous engine as I know the lengths of pipe/tube and fittings are OK - if I get the size right of course !
Apologies for queries in the meet and greet thread, but it all seemed to flow !!
Thanks for reading
