kinugawa stuff is top quality, I'm saying this from the first hand experience from stuff I bought from them.
Td05-18g are nice big tubby's but the other thread kinda proves my point why I chose evo turbo - no boost creep issues plus little] faster spool up, easy access to everything etc. Setting up the actuator to hold wastegate in place on that turbo was a challenge on its own though.
That boost creep issue on the other thread could be wastegate opening issue or too little backpressure (too fast spool up) due to exhaust system flowing too easy
The fact is what is it like when it works......
regarding this set up did u try to use a 9t exhaust size or u was using a 10.5t ??
if u was using 10.5t def u would have so much lag ,i manage last week to get a seller on ebay selling 560cc injectors and turbonoz chip i will give ita go ,also i got a nistune that im selling on ebay i my just hang on to the nistune then map it all togheter with 560cc and td05 on ca18 so it should make a good power no lag on a exhaust side 9t the smallest they do for those turbos , as there is also the 7t but thats for the evos 1,2,3 ,.from 4 to 8 the are all reverse turbos and 9t is the fastest spool exhaust housing
love your project ,cheap a chearfull
Thinking off doing something similar do you have the drawing for the adapter or would you have any ?
