my H23 head swap thread

[wed3k]

started today...
took off header, moved aside powersteering, took timing belt off
getting ready to pull the head off maybe 2morrow if i have time. (work+july 4th dinner)

need to disconnect a couple more things attached to the engine harness then it'll be ready to pull. im sure i could take the head off today but the engine was still warm and i didnt want to risk warping the block and shit.

did you know that the h23 injectors dont fit the accord wiring harness?
it has some tabs on the side of each injector that wont allow it to slide into the plug...or i got a different set of fucking injectors.

[wed3k]

got the head off today, got oil all over my inner thighs!!! YES!

umm, pistons look good, piston walls are smooth as fizzuck.

so now i cant get the crank pulley bolt off...tried breaker bar and an impact gun. im gonna have my friend bring his higher torque spec impact gun to blast this shit off.

my beater camry today got a new pair of tires right? apparently the valve stems were leaking as well. so me taking a corner r4eally fast pretty much caused the tire to roll over the rim, lol. i had to change to my spare at 5am in the morning inf ront of work.
at least i did it in under 10 minutes

otherwise...not too much progress today.
im hella tired from work and blah.

[wed3k]

once again...it is bare.



yay

boo to spare tires.

thats a lot of HEADS!!

25 dollars, not bad at all...will match my JG cam nicely.

[wed3k]

valve stems fixed oin the camry except it gets shit ass gas mileage now...put on 17 city miles and consumed like alkmost 2 gallons already.

oh well...
obx-r red rad hoses

yea, i dont know if we're gonna ever have one, lol.
no one has really spoken about a norcal one.
i wouldnt mind dyno'in my head swap

[wed3k]

you know whats crazy?
the h23 injectors fit the suzuki GSX1000r fuel inector wiring harness...

so if i really wanted, i could hack apart my wiring harness to use the h23 injectors.
but 30cc difference...is it necessary?

sigh...i dont want to starve the engine of fuel though.

anyways, waiting till monday for my friend to bring by his impact gun to blast off the crank pulley bolt.
maybe try and finish the timing belt and hook everything up?

i need a new powersteering belt since the head is larger and furthur away from the crank pulley thus requiring a larger belt.

im worried about certain things right now...
-knock sensor? (because im running a p14ecu)
-my external->internal distributor
-stock accord injecotrs...can it handle the slight boost in hp?
-will it even fucking run? lol

[d112crzy]

im sure your injectors can handle the power. ive heard of people boosting on stock injectors, with no fpr, fuel pump, or way of pushing out more fuel. they used uber.lol.

anyways, what about the external>internal thing are you worried about?

[gdout90accord]

so what injectors are you using ?

this h22 distributor that i got off ebay was external.
so i converted it back to internal (because i have brand new ignitions coils and ignitors)...however, the way that i did it, im not sure if it is correct.

im using stock accord injectors but thye have been cleaned/hypersonic (or whatever they use) tested...

[wed3k]

sweetness, shaved off the tabs off the h23 injectors to make them fit the harness.

just a p14 ecu that came with the head...

i remmeber someone mentioning the cc's for the injectors

like 260 for accord
290=h23
310=usdm h22
340?=jdm h22
