69sroadster Posted August 31, 2013 Share Posted August 31, 2013 I may finally have some more cash again to work on the sr20det mods. Nobody seems to have any real tech data concerning the powerband shift when switching to the tomei 260 solid lifter cam assembly or the 270 cams. Anyone on here have some dyno backed data other than the standard conjectures? I'm tired of the bench racers personally in the SR crowd online.

emoximuu Posted August 31, 2013 Share Posted August 31, 2013 http://zilvia.net/f/tech-talk/124925-gt2871-users-sr-motor.html Check out this thread in regards to SR motors. If I decide to do a SR again this will be the general build I look at. Quote Link to comment Share on other sites More sharing options...
69sroadster Posted September 5, 2013 Author Share Posted September 5, 2013 There was some good info on there for the GT2871R and similar turbo. I'm going to replace my aging T25 with a top mount twin scroll EFR 6758. It seems like the solid 270 may be a better fit. Quote Link to comment Share on other sites More sharing options...
69sroadster Posted April 14, 2014 Author Share Posted April 14, 2014 Not sure anymore if I can get the twinscroll 6758, but don't care too much anymore about that. Once I get my PFC tuning done, I'll repost what the results were from changing over to the solid lifters, bee-hive springs, bronze guides, tomei 260's and titanium retainers. It's killing me right now staying off the boost pedal, but I don't want to detonate on a leaned out motor. Quote Link to comment Share on other sites More sharing options...
CasperIV Posted April 14, 2014 Share Posted April 14, 2014 I'm looking to go EFR as later this year after I get the basic package tested and any other bugs worked out. Right now I think I'm going to go with parts from Full Race, a Haltech, etc. I was looking at cams and the last ones I was planning to look into when the upgrades start are the Jim Wolf 260 S3s... but really it will depend if I am staying true to a small turbo plan or if I end up going bigger. With the gain in response of the EFRs I have a feeling I might go somewhat larger than I would with a traditional turbo option, which may also make me want to look at something 270 or so. Have you played with any SRs with EFR turbos? Quote Link to comment Share on other sites More sharing options...
69sroadster Posted October 27, 2014 Author Share Posted October 27, 2014 Not yet with the EFR's but I would love to. I need to get my SR to a dyno to see what difference the move to the solid lifters and 260's did for another baseline. I'm still running the stock ECU and injectors for now after realizing I didn't have the time to learn the Datalogit tuning software on the PFC. I had some drama after trying out the 550 injectors for a bit when one of the lower seals started to get pinched and dump fuel. I fixed it all and put the original injectors back in for the time being. Quote Link to comment Share on other sites More sharing options...
