What you said does not mean anything. There are many more atributes to describe a turbo than the exhaust housing flange.Quote:

In the case of the skyline turbo, they are either 45 or 60 trim (cbf finding out/measuring) and .42/.48 a/r. On a 1.8litre motor, revving to 8 or so like the vtec motors do, at around 10psi you will be pushing it in terms of keeping compressor efficiency about 68%. Now, the .48 exhaust housing is tiny. Your compressor will be pushing the air just fine, but up high this little bastard will be a wall in your exhaust and you'll drop torque off at maybe 6,000 or so, as opposed to peaking 1,000rpm later. You certainly could run more boost, but you wouldn't make any more power.
Do not run a block guard. They are piles of garbage and belong only in the bin. Stock sleeves are fine for a lot more power than you will be producing. Detonation cracks sleeves, not moderate power levels. Honda-tech is home to many people pushing 500-600whp+ on stock sleees. Just make sure your tune is nice and tight.
Are you tuning yourself or paying someone else to? Because if you are, there are far cheaper options than Hondata. Same job, quarter of the price (though, they may be a little more tricky to setup and get the job done with hehe).
