Hello Everybody,

I Got A Big Problem Need Some Opinions From People Who Been There Done That. Buy A New Engine Or Rebuild The Same Engine, Rebuilt Turbo Ready.

You Guys May Be Asking; What Happened To Your Engine? Well I Had Miss Shift Gears While Trying To Downshift, Caused My Engine To Over Rev And I Blow Two Pistons And Rods; Crankshaft Is Also Missed Up. Honda Tech Also Told Me The Pistons Shoot Up And Valves Were Missed Up As Well. I'm Assuming Everything Inside Is Broken. What Should I Do Used Engine Or Rebuilt Engine with Bigger Internals.

Bigger Internals. A Friend Told Me To Go With Titanium Internals. But I'm Not Sure From Where I Should Buy The Internals. Give Me Some Opinions

Thanks Guys

Budget $3000 Will Extend To $5000

Thanks!!!

Do You Know If It Comes With All The Stuff Needed?
Valves, Valves Springs, Pistons, Crankshaft, Etc.
The web link above only shows fully assembled short block, that means you'll get brand new crankshaft, rods, bearings, pistons, oil pan-oil pump and all the other stuff installed to the engine block. But you won't get cylinder head parts with it.

If you only need valves and valve springs, you should buy it seperately. They are not expensive though. Make sure that your cylinder head is in good condition to use it again or buy brand new cylinder head.

Here is the web link of cylinder head with all parts in it. (if your cylinder head is NOT in re-usable condition)

ENGINE SUB-ASSY., CYLINDER HEAD for 2008 HONDA CIVIC SEDAN|10003-RRB-A02

If you only need valve and valve springs (if your cylinder head is re-usable), you should look the following link and choose what you need

OEM HONDA CIVIC SEDAN 2008 VALVE - ROCKER ARM (2.0L) parts

You'll probably need brand new cylinder head with all parts in it (the first web link), because messed up valves cause damaged/worn/broken valve guides which you have to send the head to machine shop for rebuilding it. If you choose to rebuild your cylinder head, inspect every part properly.

Don't forget to buy new cylinder head gasket, timing chain and tensioners btw.

Getting brand new engine rather than rebuilding it is much safer and peace of mind way imo.

For that budget you can find a used k20a if you want.

but honestly i'd swap in a k24a2... more power more torque and save yourself some money

I agree. Go find a $300 dollar Honda CRV block from a wreck, and with you K20 head it will make your car feel like it's supercharged. Especially if you run mild after market cams. Yes it will match up to your tranny perfectly. Though since it will sit higher you might need a modded header or a used skunk 2 megapower header which fits K20 / K24 engines builds.

If you don't want to look for a K24 block talk to KMOD Performance....or go to their site.
They can sell you any block in perfect condition, add the new forged internals you want, cams, or they can build a 230 whp K20 / K24 to a 300 whp naturally aspirated k20 / k24 and ship it to your door or your tuning shop for installation.

BTW it's a good time for a new upgraded clutch to be put in.

Nothing beats OEM internals for longevity. Buy a low-mileage K20Z3 from a wrecked Si.
That's what I'd do. It's a great motor as it is IMO and finding a wrecked Si shouldn't be too hard -- people really like crashing their Si's from what I've seen around here :p
