Hi all, I am going to be putting a L28ET in my early 260Z, and am thinking of puting on a better turbo that will support up to 20 pounds, but will be driven mostly at 14-15PSI. I was thinking of goint to a T3/T04E hybrid turbo. I am fairly new to turbo setups, and would like some opinions. Alot of them have the 5 bolt downpipe setup, and some with a round 4 bolt, but I have seen some that are a V-band setup, are these better? It looks to me that they would be less restrictive, and you could fit a larger downpipe with them. Are there any advantages to the V-band setup? What about exhaust leakage? Where are you guys reintroducing the wastegate pipe into the exhaust, or are you just running a dump tube? I am wanting 300-375rwhp, and it will be driven alot during the summer at 4500+ ft elevation on pump gas. Also are all the ebay ones junk, or are there some that aren't too bad. Anyone run a cheaper off brand with success? Most of the Garrett ones seem to be $500-$650+. One more question, at these power levels is a forged piston mandatory? I would think they would be, but if I can spend the cost difference between cast, and forged somewhere else on the car, I would. Sorry for all the newbie questions, and I have searched alot already.
Thank you for any info.
