Know anyone who has actually used them yourself? Soon as i see £150 turbos i get ebay special chinese nock off shudders.
But as said nitrided will do the job (as banny shows), a known quantity and cheaper.

And what is nitriding if it isnt heat treatment?! 🤔

I ran an exedy twin plate clutch and I preferred the pedal feel to the ACT I had in the type r I just sold but then again the twin is almost double the price.

it is but totally different process to "std" heat treatment.................
to better explain
the EJ20 STi cranks are still manufactured in "nitrided" form and have a matt BLACK appearance.......
the EJ257 crank is no longer available in nitrided (ceased approx 4-5yrs ago!!) and is supplied these days in a std "heat treated" form and have a mainly steel finish with heat / rainbow marks

Well the car is long since dead (engine is going strong in a mk1 escort ran by CAMS) I drove it for a year as a daily to work and back 14 miles round trip and was a pleasure to drive and no issues in traffic.
I ran an exedy twin plate clutch and I preferred the pedal feel to the ACT I had in the type r I just sold but then again the twin is almost double the price.

£150 sounds dear! My £125 td0520g is performing excellently, recently pushed my newage into the low 12's.
