Crower 403 b18b
I have another engine with a lot less miles off an automatic and another tranny In my garage so im just gonna keep reving it till it blows, my care doesn’t smoke at high rpm so I doubt it has floating valves yet at about 8500 rpm Is when it smoked nasty and loose power all off a sudden so now i just rev it to 8

I can't understand how you keep pouring money into the engine without fixing things that are obviously wrong and saying F' it, I'll just put another one in when it blows up. Why not just do it correclty?
Lol I am still trying to figure out what the smoking at high rpms has to do with floating valves...
Is he trying to say that the valves don't float until 8500, so he set the limiter to 8000 and thinks thats okay?

Seriously.... just upgrade the valvetrain lol

Rocket sells a set with more reasonable seat pressures that work with stock retainers too. The crower and BC ones are very unnecessarily aggressive for the lift that the 403s make and make me nervous with the P75 head’s tendency toward sinking exhaust valves.
I want to build a p8r head and I don’t have money right now to spend on the valve springs that’s the main reason why I haven’t done it yet I might get around to it around February but for now i should lower my redline to 7000 to be safe
So I ended up boosting my integra , the head is still the same , same cams, intake +3 exhaust +1, ram horn headers tc-26 Godspeed turbo 3 inch down pipe to two inch exhaust rsx injector 550 redline at 7900 at about 8 or 9 psi ls tranny , it breaks them loose in second with just gas and in third it almost wants to break them loose but needs a better clutch I have a stage one exedy , I love my setup it feels so easy to drive and makes plenty of power to keep up with anything around town
Hmm, very interesting! Back in my day I had almost the same setup but I had 404s with springs & retainers. It was in a 1993 DX Hatchback and paired with a B16 tranny. Best I ever did in the 1/8 mile was a 8.80 with 14 inch slicks.
Not sure what happened but the engine started smoking from the breather and the dipstick, my brother brought it back like that one day. not sure how it happened l, but before that I had done some full throttle pulls on third gear and I didn’t notice anything strange, it was fine when I parked it last, and it was a 3 inch down pipe to 2.5 inch exhaust made power past 8000 rpm easy
I’m fine with the power the car makes I just want it to rev safely to 8000 rpm what parts do u guys recommend those of you who have built a 250-300 whp b18b , which pistons rods hardware headgaskets and yes I’m finally going to put those valve springs in
Do you have some weird form of autism that doesn't allow you to read or comprehend anything? It's like you are blindly talking to yourself and ignoring every word of advice from everyone on this website.
Anyways, lets start fresh. You want to build a b18b that is safe at 300whp and 8000 rpms?
Assuming that your valve guides/seals/, rod/main bearings, cylinder walls and piston rings are okay, really you would just want to upgrade the:
Valve springs
Install ARP rod bolts and Head studs
Install a new oem head gasket
Then you should be okay. The factory LS internals are okay up to about 300whp with good tuning (stay conservative on the ignition timing, boost and AFR). ARP rod bolts and head studs should give you some extra insurance.
If you want to really be safe and do it right (not a snow ***** chance in hell, the way this thread has been going lol), I would:
Refresh the cylinder head (Resurface, valve job, light porting, new guides and seals and a hot tank).
Hone the cylinders, clean up the pistons, then rering the pistons with a slightly bigger ring gap.
Clean up the rods and have them shot pinned.
New oem and color matched main and rod bearings, with slightly larger tolerances.
New oem water and oil pump, new oem timing belt and new oem gaskets and seals.
New oem spark plugs (1 step colder and properly gapped) and new oem wires/cap and rotor.
I would imagine that engine being fairly safe at 8000 rpms and 300whp. If you want to push further than that, you will need to go forged internals and even further you will need to upgrade and or reinforce the sleeves.

It cracked some ring lands from running lean and too much timing but my new engine has been fine after about 50 plus pulls and a couple of two hour trips it been running about 11 psi occasionally and 9-10 daily the tune is a lot better and rev limit is alot lower as well https://youtu.be/lRVr0hRbUkA
