yes...for sure. i havnt really dealt with any of the GT series turbos smaller than the 35R....but i know right off the bat the GTR series turbos are where its at....its all i want to use on my car from now on.....if you can affored it go for it.
ALWAYS go with something a little larger than you want....just like you said you WILL want more power down the road! unless your set on the power goals you set i'd even consider the GT30R's.......i actually prefer a little bit of lag....and the whole "lag" thing is something you need to experiance first hand to understand that its not as bad as people make it out to be as long as you dont have like at PT70 on your car or something... the bigger GT28 is rated at 440 Flywheel horsepower...but the GT series turbo's are underrated.......keep in mind that if your going with a smaller turbo and want to make 350-400whp its going to take a lot of boost. thats the nicer part of going with a turbo thats slightly larger...you can make the same horsepower at lower boost levels which is better on pump gas.

not sure on PSI....i'd say just run a low boost setting of 10-12psi and then a "fun" setting at around 15psi on pump gas. should make the power your looking for no problems.

i like compression with boost when on race gas.....but for a pump gas car i'd just stick to 9:1

boost response between shifts is much much much much greater with a ball bearing turbo too 
also....another thing i think is funny about the whole "lag" thing........ even with a small turbo....a lot of times the gauge will say 5psi or so but the car still isnt going anywhere.....like in 5th gear if you stomp it going up a hill......sure the car will make boost at a low rpm....but its not going anywhere...so who cares! you will be happy with the turbo you have selected

nah....you want a smaller wheel with a bigger tire for traction. the more sidewall the better. just like on slicks....we run 13 inch wheels with 24.5 inch tire. more sidewall = more traction.
9.5 compression will be fine, just leaves less room for tunning errors than a 9:1 piston

, I just want 300 - 350whp NOT BHP with a nice torque no laggy and good response but also top end I think this turbo seems well good for it. T-charged what psi you reckon I can manage the power goal?? i saw a GT28RS vs a GT3071 in full race site the dyno is hosted by evans tuning ... wow the torque is amazing and made more power/torque than the GT3071 everywhere i think this was at around 11psi on stock b18b only problem i think there was that the turbo doesnt produce power till the redline and i wud imagine even so on a b16 which revs higher.
.the tuner iam getting is apparently very good, going with 9:5:1 will also help in down low response. i know what you mean the about the 5th gear, my cruising is mostly done in 4th gear and around 2400rpm 57km/h more or less.. remeber i live ina very small small town. use google earth and search gibraltar you can even see my house the roads even my car althought it just looks like a white blur lolol . finally .... I know this is may be a stupid question but no matter.. lol originally i was gonna go with 16" light weight rims cos i had the vortech ... now iam thinking ... more power better powerband more torque... 17" wud seem better at gripping right? and also i cud fit a nice four pot break kit under thea.
