So about a 6 months ago I revived a 90 240sx coupe in a trade for a mustang. The 240 has a sr20det red top swap running a greddy TD06-25G T67 turbo kit. the car pulls like mad but the TD06 takes days to spool up hitting full boost around 5200rpm @ 1.4bar so I'm looking into swapping out turbochargers And manifolds. I've been reading up on the Percision 5558 turbo and in the .63 AR version full boost seams to come on at around 4100-4200 rpm @ around 20psi. Now my question is if anyone has experience with the 5558 turbo in the .48ar on a sr20 and would know about the spool and power Characteristics would be? And dose any other suggestions for a turbos that are well with in the 450bhp range with good spool up?

Now the greddy TD06 that's on the car at the moment uses a 3 bolt flange to connect to the exhaust manifold is there a name for this flange and is it Specifically for greddy products?
