Assuming the engine is built properly, is 300whp any easy mark to hit? Not nessesarily daily driven, say 240whp on a daily unless it of course it will handle 300 on a daily basis.

I don't know anything about those motors but it's easy enough to do that on smaller B series motors so I don't see why not with sleeves/rods/pistons.

 

Piece of cake!

 

that's sweet. 300whp in a 93 accord sedan with a bone stock exterior minus rims that runs a mid to high 12 in the 1/4.

I like it

 

amen sounds like you are on the path I am on, only I am using an h22a. 300whp should be cake ecspecially with a built bottom end and proper fuel management/tunning.

 

not hard at all, especially with a built motor. make sure its tuned.

 

i'd say its pretty easy with a built motor. Boostedh23a has 250 whp on stock internals (i think the internals are stock) but he hit that 250 on only 7 lbs. So build it up the boost and you'll have your 300 whp

 

i got a beat up h23a1 with tranny and ecu for $400cdn from my friend who also doubles as my mechanic. It needs to be rebuilt so i figured hey, great candidate for boost.

 

its very easy to hit the 300whp mark with the h23a motor. My h23a1 will be putting out right at 450whp with the new t4 60-1 that im upgrading to. And yes, i will be running c16 octane. If you are interested, i have the perfect turbo for you if you want 300whp, it is a t04e ball bearing turbonetics turbo in perfect condition.

 

my goal in about 6 weeks is 400whp with my new setup on c16 and 320-350whp on pump gas on low boost am runing high comp

 

Would you guys recommend higher compression or more boost to hit the 300 mark. I was thinking to run about 9.0:1 pistons. should i go higher or no? If i end up using the car to commute to and from school then i'd turn down the boost so would it be better to run a higher CR?

 

300 whp : Easy.
Daily driven: No problem.

if you sleeve it, put new rods and pistons, it'll hold all the power you
can make with 550cc or 650cc injectors, increase the boost until
you max out the injectors. 550's will get you to 325 whp
and 650's should get you to 390 whp.

run lower compression (9:1 is good) and then you can use pump gas
and it'll be more relaible (in theory) than a high compression motor.

I don't want to get into the high vs low compression discussion, but
the higher the compression the more 'touchy' it will be when tuning.

Let the boost do the work for you. Run 18-20 degrees timing and you'll have no
worries.

Spoken like a person with experience.

That name looks familiar from another board rimes with cortex

 

cool, looks like i was already on the right track

It's gotta get rebuilt so the sleeves were already on the list and i like the idea of being able to survive on pump gas with the 9:1.
