ok ive searched and searched even on the rb20det huge kilowatt how to forums that I cant get to load,have the usual mods stock injectors,mines computer,fmic,bee,r,rb25 afm,walbro 255,rb25 turbo running at 15 psi,higher voltage fuel pump.goes well flat to the board afr is about 11. im almost about to buy ths kinugawa td05 18g 8cm.i want similar response to the 25 turbo but I also want a nice hit from roughly 4500 upto 8000.my neighbours s15 pulls really hard with his turbo upgrade and injectors...I want the same..i am gonna install gtr injectors,z32 and a nistune.I suppose I want to be able to get about 260 rwkw.is this turbo gonna get me there or do I need to get the td06 ?? only street driven.so I suppose the question is what turbo similar response to rb25 but with the biggest push in the seat up top.i know this has been covered before but I cant find enough info or I find a lot of the links don't work.what would be the best td turbocharger for my needs.cheers in advance....
