Heres part of one of my emails with jeff. hes a real good guy, and I trust his advice.
The H motors have serious oiling issues, and balance problems with big
power. You can look at the Honda helms manual to prove it. The #5
journal
asks for like say .0011 clearance, and the #1 journal wants say .0016.
That's not a good sign when Honda is already admitting through the helms
that the block has oiling problems, and to make up for them, you have to
progressively clearance the motor from 1-5. Its also got 2 balance
shafts
because its not really well balanced. It "can't be really well balanced
with 1 journal is a lot tighter than others, the loose end is going to
have
more vibration. So they put the 2 balance shafts in to "help" it.
Never run the motor without the balance shafts or stock, heavy crank
pulley
that is dampened.
Then there is the tensioned issue. H23 tensioned should be20used only on
every H motor.
Then the piston to valve clearance is an issue on Preludes as well.
There is no other Honda motor in the last 15 years that has as many
problems
as the H. It's the worst. When you put a lot of power to them, it
makes
all the problems more severe, and chances of failure compared to other
motors increase dramatically.
Then you add to it the fact it's a LOT more labor to work on a Prelude
than
it is K or B series, you get a full picture of the situation.
I am a Prelude expert, I can tell you all about anything on the motor,
in
detail. How and why and everything.
270 WHP can be had on a Jackson Blower at modest PSI. If I were you, I
would do the Jackson kit, THEN modify it to fit an aftercooler, which I
can
sell you the cooler and radiator setup for it. A little work, and you
can
do 10 PSI on it, no problem and possible make 300.
Believe me when I tell you, 250-300 WHP on a H motor is quite an
accomplishment keeping it as reliable as possible, which is what the
build I
layed out for you will do the best humanly possible.
I know what your saying, and I understand it completely. The thing is,
I
will not sell you, or recommend any customer ANYTHING I would not do
myself.
That's why you come to me, you get no bullshit just to make money. I am
just like you, I want to spend money on something that is power
ful, yet
last
a long time. Notice 300+ WHP Preludes on the internet is so rare? And
if
you see one, its not running the next month and you never hear about it
again? Notice that?
