With no tune, you'll make less power at higher boost on the stock turbo, but your not going to blow the engine (unless you boost enough to shit the turbo). When my RB25 was just fully bolt on (ex manifold, elbow, dump, de-cat, cat back, intake pipe, fmic, etc.) on the stock ecu, I make 285rwhp at .75 bar, and 258rwhp at 1.0 bar on the stock turbo. The ecu freaks out when it sees that much air and throw's a bunch of fuel at the motor and pulls timing to keep it safe. It'll sound stronger, but it's not.

Anyways no, you are fine at 11psi on the stock ecu.

    • Been slowly chipping away at it when I've got time. Tried to get the box in with the converter but worked out that the flexplate isn't the correct thickness and the converter pulls out off the pump too much (about 8mm). The flexplate for some reason was setup to use the secondary holes on the converter which had a press in nut to bolt to. I worked with Adamat performance the guys who manufacture the kits and they revised the design and made it suit the factory converter holes and milled up a new one for me and is currently on its way over. Can see the differences between the two compared to the orignal design which is in the post above. Once that's here the box can go in for good. I dummy'd it back up to get tailshaft length and is currently with Hardy Spicer to sort that out. Unfortunately won't get it back until late Jan Have been working in the boot lately getting it all a bit nicer and useable. Painted it with sound deadener and cut out a new boot floor from 18mm MDF so I can put a pram or my tool bag in the back. Have marine carpet coming to stick onto that and then also cut a piece to cover the battery. Once ive stuck the carpet in and all cleaned up ill pop the fuel system back in. Need to order 2 new Walbro 525s to replace the 3x 460s. Should be enough fuel for the new setup and run a bit cooler as well having more volume in the surge tank and less heat.  Have also ordered some sound deadener to put under the carpet. That should be here next week and I'll start putting it down on the floor, doors and roof. Hoping all this effort will make it a nice streeter with ability to daily if I want to.
