DrphTa 5 Report post Posted March 2, 2012 (edited) How much has this cost so far in the conversion. 2g ? Edited March 2, 2012 by DrphTa Quote Share this post Link to post Share on other sites
Ben 0 Report post Posted March 2, 2012 Simple, usable power... Want to see boost before 3k lag is for dialup Fair enough I used a similar sized turbo on my last setup and had next to no lag Your not worried about boost tapering off at higher revs? I would have thought the dsr430 would have been a better match nissan guys use them and still have a low boost thresh hold Have you lowered compression or standard C/R?

I would have thought the dsr430 would have been a better match nissan guys use them and still have a low boost thresh hold Have you lowered compression or standard C/R? Not worried at all. A friends 04 Sti runs on 18psi with a smaller turbo and doesn't have any boost tapering off. C/R hasnt been changed at all yet. Might lower it when looking for bigger HP. Good ideas on lowering C/R?, I have heard of the thicker gasket trick This is my best mates car Andrew. His name is Marc "MarcG" im just speaking on behalf as he doesnt use BS at all What is everyones guesses for HPatw on 5psi? Id say 220-250hp? Quote Share this post Link to post Share on other sites

Subaru is a different kettle of fish tbh Mine has a similar size turbo to dsr380 and i have full boost by 3500 and it holds solid till redline and i could probably bring that down lower with a little more tuning Put simply with a smaller turbo your going to need more boost to reach your hp goals so if you want to retain that turbo and shoot for big hp either lower your compression or use a bigger turbo Thicker hg with arp studs works fine going off the usa forums Lower CR pistons would be best Im using standard CR with buckets of overlap and a big mumma turbo for my current build Edited March 2, 2012 by Ben Quote Share this post Link to post Share on other sites
