Hi guys! Well my b18c-R engine blew at 1.7 bar on stock block with thick headgasket, arp headstuds and supertech dual valvespring + Ti Retainers. Well, it actually did run great untill I put on some "oem denso coils", and it blew as soon as I got into full boost. Well, enough of that story. I just got hold on benson sleeved, laskey build b18c engine 84mm x 89mm, so now I'm considering if I also should upgrade the turbo aswell. I mean the rest of my system should support around 500-600hp: ARP Headstuds Supertech valve spring og ti retainers Valvecover with 2 -10an Hondata intake gasket Thermal 3" exhaust ACT 6-puck disc ACT xtreme pressure plate Exedy 9lbs flywheel Hasport 62A engine mounts OEM torque mounts Ingals engine damper AEM water methanole kit Hondata Traction control Hondata CPR ID1000cc injectors Walbro 400lph fuel pump AEM fuel rail black AEM fuel pressure regulator Turbo: Full-race ramhorn AC compitabel manifold Garrett GTX2867r .82 a/r Full-race 3" DP Intercooler from Full-race painted black Tial 44mm wastegate Tial blow of valve IC piping from full-race + custom pipe, 2.5" cooling: Mishimoto x-ine full-size radiator -16an fittings and hose Setrab 60 row oilcooler with -10an hose and fittings Mishimoto sandwich w/thermostat Spoon thermostat Spoon fan switch 1.3 bar radiatorcap I really like the responsivness from the GTX2867r, but with the new engine, I could easily run a lot more power. But the car is used as a daily driver in the summer + circuit racing. The turbos I consider is the GTX3071r or GTX3076r, GEN 2 of course. I would love the 76 because it will support more power, but how much slower spool and shorter wideband would it be? Anyone running these turbos?
