TravRMK Posted May 7, 2007 Share Posted May 7, 2007 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. Quote Link to comment Share on other sites More sharing options...
TravRMK Posted May 7, 2007 Author Share Posted May 7, 2007 Also would a .48 AR turbine support 300+rwhp, or do I need to go with the .63 AR? And would an internal wastegate suffice? It sure would be alot more simple on the instalation. I also plan on puting megasquirt and Spark in the car. Quote Link to comment Share on other sites More sharing options...
Clifton Posted May 7, 2007 Share Posted May 7, 2007 You could do 300 rwhp with a .48 but it would take ALOT more boost to do it. Cast pistons are fine, don't detonate. Quote Link to comment Share on other sites More sharing options...
TravRMK Posted May 7, 2007 Author Share Posted May 7, 2007 So a .63AR with the t3/04e? What about a Holset? I have read alot of people on here running them. A hy35, or hx35? Some of them seem to have funky outlest on the turbine housing. Would this be a good way to go? BTW Clifton, I like the color of your car in your sig, what paint is that?

There are different turbine and compressor trims for what you listed. I would run a 60-1 but if you are set on an E trim, I would go with a 50 or 60 and atleast a stage 3 on the turbine. I don't know what Holsets flow. Quote Link to comment Share on other sites More sharing options...
