Any hp goals? turbo size? or just a stock turbo kind of build. btw take that honda emblem off your subs hahahah will get crap for it here
with that kind of miles, i honestly see a serious head ache in your future, boosting an engine with almost a quarter mil on it is just asking for problems.
If i was in your position, and i had the money, resources, and perseverance, i would just rebuild the engine, or do a stock tune + Dv and cat delete, then start saving for an overhaul, before something catastrophic happens and your head or block or crank become garbage. Engine builds dont happen over night, it would be a long, drawn out, excruciating process, but is so worth it in the end.
Drop in IE Forged rods
JE Pistons, keep Stock bore + rehone cylinders
Fresh hardware (weather its stock or ARP or Euro or whatever...)
Fresh bearings (doesn't have to be performance, but if i had everything out, i would throw something performance in)
+every seal, gasket, O-ring, anything you can get at while the engine is out (aka everything)
I know it sounds like alot, but look at the other route...
you buy a stage 1 tune, like it alot... but after a few months you want more (you will)
So you decide to go a little bigger because your on a budget, so k04 or franken turbo will probably be what you pick for the next step up of an upgrade, next thing you know your boosting 20 lbs on an engine with 250k... in the end somethings gonna brake... and when it does, **** around it will also be destroyed aswell (cylinder walls for example)...
Go stage 1, and start a piggy bank, because weather its for a BT build or an engine overhaul from catastrophic failure, you WILL need that money one day
