Fully built D15 how much boost?
 

building a Built D15 in a few months need to know how much boost it will hold so I can piece together my turbo kit and find out what I can run.
ENGINE COMPONENTS
1.5liter with 30K, JE pistons, Eagle H-beam rods, and block guard, how much boost can I pump into this or what can I do to make it stronger?

I have a IHI T3 turbo to put on this engine

First of all, I wouldnt use a block guard, because they do more damage then good. Either sleeve the block, or Post/Pin it.

Since it sounds like your dumping alot of money in this engine, you dont want to cheap out in areas like turbo/engine management. If it is built up how you say.. The engine can take a good chunk of boost, I would go with a T3/T4, .48/.50comp Turbo. Get yourself a nice set of 450/550cc injectors, Hondata/Zdyne/EMS (maybe the afc hack)
and you could easily run 15psi if not more. But its all in tuning, not how strong your engine is. Spend lots of time on the dyno to get everything dialed in perfectly...

People will have a nice built engine, and run stock injectors with a homo ass turbo, turn up the boost and blow the fucker. Engine management is everything.

That turbo you have is crap, ok for a stock engine, but if you want to make power. You need something larger.

yup, good managment is everything, that's how i'm running about 2.3bar~33/34 PSI on stock 13bt reman motor with lead. it's not how everything is built, it's how it's bein control'd, upping the boost will still cause (LEAN conditions) and then BAM no more motor.
