Ok so there are a million threads about the 18t vs the 19t, but I am wondering what the physical difference is.

I am building a honda ZC with the old skool greddy turbo kit. the td04h-15g that came with it was toasted, so i swapped a jukyard td04hl that i rebuilt, using the 15g turbine housing.
because of my bad tuning, i ended up damaging the compressor wheel, so i am trying to replace it. I ordered the 19t wheel and the one that i received had a 58mm exducer, while my old one had a 56mm. is this an oversize wheel, or do i have an 18t? I cant find any solid info on what the oem 19t or 18t wheel specs are.
thanks :)
 
You need the chra machined to accept the 19t compressor wheels. Kinugawa sells a 19t compressor wheel that doesn't require machining but it's like $120.
 
so is my turbo an 18t? it came from a 1999 or 2000 v70 2.4 t
compressor wheel is superback 40/56mm
and it had the integrated BOV
 
Just went thru this...
Turbo with angled housing sourced from a 99v70AWD.
Milled CHRA housing for 19t compressor (58mm) and milled compressor cover/housing for same compressor. Both areas pointed to in red need machining. Normally about $100-$150 each.

18t is a small turbo. Find a he351 and have some real fun! Or a new fancy BW if you wanna spend some money.
