Psbdeck Posted April 14, 2021 Share Posted April 14, 2021 Hey all, A question I'm not just 100% sure on and maybe somebody can help. I got my hands on a set of pistons and rods for the vti deck. Now on closer inspection it appears I have got type r rods and pistons. So the question is, can I put these straight into the standard c4? Mixed answers online. Some saying cams and a map are needed. Or would I be able just to put them straight in with no real.dramas? Many thanks all. Quote Link to comment Share on other sites More sharing options...
noodels Posted April 17, 2021 Share Posted April 17, 2021 (edited) FFS Tech | B-series Piston Check (ff-squad.com) gsr has little more CR than b18c4 <10:1 ?>so be about this below and would be better without the snail inlet manifold and p28 ecu,but try it maybe ok with 98ron gas,you need to know what you have also.. P73 JDM pistons in B18C w/GSR head CR=11.3-4ish P73 US pistons in B18C w/GSR head CR=10.8-9ish Edited April 17, 2021 by noodels Quote Link to comment Share on other sites More sharing options...
