Default Leak down and Compression test results

Well i bough a 92 DX hatch last week of a friend (WAY too good of a deal to pass up ) The car had some problems...Ghetto SMC management (running WAY rich), Hacked wiring, dented oil pan/shitty oil return) that needed fixing and my friend just wanted rid of the car...Anyways i fixed all the wiring issues, ditched the SMC and tuned the car on uberdata.

Setup is:

b18c1
9:1 JE's
Eagle rods
JG Pro series head (complete valvetrain/valves/PnP)
Drag 3 turbo kit
Uberdata
DSM 450's (temporary )
Walbro 255hp

Results of the comp/leak test were:

165, 165, 170, 162

2%, 2%, 3%, 0%

The car runs perfect part throttle and idles perfect. In boost it still smokes though and i can smell the oil. Im wondering if it could be the ghetto *** return/pan setup (new one goes on this weekend) or possible teh turbo (ive hear story's about the older turbonetics used in the drag 3 kits having problems with the seals )...

how much did you get it for??? compression seems kinda low, but still consistant.

my 9:1 b16 pulled the same numbers and made 260whp @ .45 bar

Paid less than $4500 for the car, it also came with rota slips, Golden eagle intake manifold, GSR leathers, etc..Car is white and no rust/clean body (hard to find for less than $3500 STOCK in the northeast ) Im swapping the turbo/injectors and bunch of misc. things off my sol onto it...Should be an easy 400+whp setup

These numbers can be quite different from one compresion tester to another and at different altitudes I would assume as well. It is just important for the numbers to be consistent. His motors sounds like its fine considering his leakdown numbers look good and his numbers are consistent.

your numbers look fine for 9.1 compression, and i think your in the right derection with the turbo being the culprit
