Reliable Amount Of Power on Stock D16Y8 with Boost?
So i am boosting my D16Y8 and im going to shoot for 200whp. I've got a T18 turbo and will probably be pushing 8-10psi. Just want to get some on input on if my stock internals will be able to handle that power/boost safely as this is just a fun daily driver and i plan on driving it all the time. I've looked around and have found a lot of different info on what is a safe amount of hp/boost to run. Any input helps. Thanks in advance.

You should be fine if you don't go over 200whp and 8-10lbs is right about where you want to be.
Make sure you get a good tune. Personally, I would replace the Rods and crank. A6 rods and crank are a little stronger and the crank has dual oiling holes, so it's much less pron to spinning bearings. Also a set of ACL Race main bearings w/ 3/4'' oiling gap, instead of oem 1/2''. Swapping your wiring from OBD-2 to OBD-1 give you greater tune-ability. y8' have an inferior water pump, which contributes to spinning bearings. Only after swapping to OBD-1 can you run a Z6 oil pump, which is much more reliable. Last, but definitely not least, the head bolts/studs. This is the crucial point of stress. It's highly advised on most every D16 Turbo thread out there to install ARP head studs, they are a good cost effective ($100-$130) assurance. The head gasket is a common misconception. No, you don't need a Cometic MLS head gasket. Any quality MLS will do. Don't install a graphite gasket and you'll be fine. So, that's my advise. Hope your build goes well. Here's what I run in my crx: D16Z6 Block/Head Chipped 28 ECU D15Z1 -16 dished Pistons Eagle H-Beam Rods (had to notch the block) ACL Race main bearings w/ 3/4'' oil gap King Rod bearingspiston rings NPR Piston rings Fel-Pro MLS Head gasket ARP head studs D16A6 main drive pulley (Heavy as hell and yes, has built in damper) DSM 560cc Injectors P20 Hydro trans w/ LSD Re-surfaced OEM Flywheel (stock weight = more inertia that helps hold boost longer) Yonaka Stage-3 6-Puck clutc Fresh build. Running a kkk k26 t3 Turbo @ 13psi. Good so far. |
Ok ya i got my car tuned to 190whp. I've converted to OBD1 (P28 w/hondata s300). So does that mean that i can just switch directly over to a z6 oil pump with no issues or is there something i have to do in order to swap my Y8 oil pump for a Z6?
Oh and maybe a stupid question but can a swap out the rod bearings by just taking off the oil pan unbolting the rod and then swap out the bearings? |

If you have an OBD-2 harness, with an OBD-2 to OBD-1 Jumper, then you have to rewire the oil-pressure sensor clip, with an OBD-1 clip. Yes, you can. I've done that before. Lawl. You have to unbolt the block cradle too, ofcourse. Not a big deal actually. |
Ok, now i when i was researching the oil pump issues. I found write ups on guys porting and shimming the stock pump. I found that a lot of people said that you should have around 80-90psi oil pressure around 3000rpm when it is shimmed. HOwever my pump has that 80-90psi without a shim. Would i be better to just port the stock pump then?

Hey, If it's not broke why fix it?
If your running 80-90psi, then (If I'm right) you dont want to increase much. I think shimming the pump would be pointless, since your already just fine. Are you sure it isn't swapped to a D16Z6 Pump? How many wires does the sensor have? |
Ya its not a D16z6 cause i have a dip stick, and from what i found if you convert to a z6 pump you lose your dip stick. So i'm thinking i might just port the pump and call it good.
