Can someone give me the specs on a JR Adkins lil 55, I've got a guy wanting to trade me a HTT 62/12 like new for mine, and need to know how it compares, I'm wanting compressor size, exhaust turbine size, and any other information you guys have to give me

Compares to a 64/14. 1050 to 1100 CFM of air. Known to be found with 22 or 18. 5 exhaust housings. The 16 and 14 mm exhaust housings are machined to fit. 64 wheel. J. R. likes a big turbine. It will spool (on my 24 valve) around 1600 to 1700 rpm.

I must be doin somethin wrong then... mine refuses to light before 2000 - 2100, I'm running the 16 housing, I'm not sure if I'm running enough fuel with the detune I've got right now for street and winter driving or what, but it's not too hard to cruise with 0 boost pressure... . any ideas?

 

[Kissfan113]

also what kind of boost should I be expecting to see... I've been getting 20 - 25 WOT on the road tops

Theres something wrong, Boost leak, bad bearing or wastegate stuck open, I dont know but that thing puts out way more than that.
