Hearsay? No. Common sense? Yes.
So you’re saying that you’d spend $3,500 on a kit with a cast iron log manifold and a non-garret non ball bearing turbo roughly the size of the T25’s from the SR20’s?
Or
$3,300 on a GT3071R + Tial 44mm Wastegate + Best.KA.Manifold.Period + 3" SS downpipe?
All you need is injectors, and ECU tune, and you have the same parts for your Greddy kit.
But the Fullrace kit I linked isn’t complete, neither is the Greddy, but you can get better KA turbo kits for less than the Greddy that come with MORE.
Here
$3,000 FOR A FULL kit, with a beautiful, solid manifold + BOV + Intercooler + better and bigger turbo
Hearsay? I say truth.
