Its a toss up. If you are willing to put up with the lag then the 35r is good to go. But a general rule is, if you dont plan to push it to its full potential (in your case you dont plan to ) then go one step down. You will hate a big turbo on pump gas and low boost. Trust me, there are plenty of people putting down 420-500 on gt30’s and they spool at lower RPMS… --- _[View the full topic](https://forums.speedlife.net/t/rebuild-motor/192826)._
