Default boost on stock Ls block



how much risk of damage is there if you were to run 5-8 psi on a completely stock B18A1. taking into consideration, the engine has high mileage and it burns a small amount of oil, but compression is good across the board and runs strong. with a proper tune would turbocharging it effect the reliability ??? all thoughts welcome thanks

also the greddy e-manage "piggy back" .. are they universal between honda engines, or do they have the ability to be re-tuned for a differnt engine????? If so would it be possible to put a turbo kit originaly for a D16 on a B18A1 if I repalce the D16 manifold with the proper B18 turbo manifold... i would appericiate any knowledge or advise!! or if some one has done similar things love to hear how it turned out .......thanks

yes it is possible to use that kit but the kit probably isnt matched well for the b18.... you would need the new manifold and possibly downpipe. as far as the management stay away from the greddy shiat. you would be better off piecing a kit together and having it tuned on hondata or neptune... or even crome

Don't piggyback the computer, get a real EMS and tune that ****. No FMU, no emanage.

If you want to turbo your car, don't be cheap about it.

That motor with a small turbo has a possibility of running probably 13-15 lbs of boost on it reliable. With a larger turbo, 5-8 lbs is sufficient. Different turbos will give you different power results and IMO, it's not the boost that breaks stock motors, it's the power level.

Turbocharging your car will not hurt the reliability of the motor as long as it is done right. As long as the setup is tuned properly, routinely taken care of, and not completely abused like a jerry springer wife, the longevity of the setup should match that of any normal motor.

I'm no pro at this whole thing, so things I have written will get picked and poked at, but I do have plenty of experience working with these systems and these are the patterns I have seen to hold true.

If you do decide to turbo your car, do it correctly and don't cut corners. And in the end.....

Enjoy it.

If you are going to switch out the pistons why not just go ahead and do connecting rods also since they will be out the motor? Im guessing around 350hp or so on stock bottom end.
