Well i bought a db8 shell with a db6 front end. I wasnt going to buy the engine but here i am posting. Its a boosted c1. Sure it sounds cool at first but then i learn more about it. Its a C1 with b16 pistons which would jack up the compression. I speak to the engine builder and he said he built it as a high compression engine. Didnt build it for boost. Well here is what i found. Compression on #2-4 210, #1 120. Leak down test revealed either a burnt piston or the rings are fried.

"now me and the mad scientist have to rip apart the block and replace the piston rings your fried"

Sorry couldnt help myself

Here are the "build specs"

lightened fly wheel and was balanced before installed

.58 ebay turbo boosted on 9psi with a street tune on crome (p28 ecu)
3inch down pipe to flex pipe and 2.5 full apexi exhaust car sounds mean and bov is LOUD (hks ssqv limited black edition) all motor work was done by Nate at Daily driven motor sports i can meet up at his shop he can show proof of work probably about 15k on rebuilt


Forgive me for my ignorance, im a chevy guy but as you can tell ill get into other stuff.

So it sounds to me like this motor has to be over 11:1. Sounds like a bad formula to boost. Im obviously rebuilding it. What do you guys think would be the best route. Take the turbo off and build an all motor deal? I love boost just like 95% of people out there. Any tips and advice is appreciated.

Nothing?

 

You'll probably get more input over in the forced induction section then here, https://honda-tech.com/forums/forced-induction-16/. I wouldn't be scared of high compression and boost though. Its better to run lower boost and have the motor do the work then run a low compression and have to run higher pressures to make up for it.

 

I'll start it there. It's just the questions has n/a and boost in it so I just put it here . Thanks

 

No problem. And it depends on what your planning to do with the car. If you plan on just having fun with it, you can't beat boost. My cars been boosted for 4 years (stock b20v) and theres never a dull moment while driving it.
