[QUOTE=tradiuli;44357424]Very soon we will upload the car on Dyno , but I have concerns whether the block will last about 500whp



This is the Block


WTH is those lil pins doing there...?

 

ill assume its to keep the4 sleeves from floating around due to heat, and abuse

more of a stabalizer

think of a block gaurd

 

There are several Honda in my country made with blokgard, but because no proper seal is broken ....
Pins on my engine is putting up cnc milling aluminum with the same extension as a block and 1 percentage point gap .....
Similarly, my friend makes B20 with 400whp already one year without problems

 

You'll need a great tune and some luck to have that last at 500whp. Those pins seem to help but they're still stock sleeves

 

why i had a completely stock gsr last me all summe rlond dailey driver over 50 passes at the track with 500hp block is still going strong as well.

that was on 26psi

 

On 93 octane?... Plain and simple 500whp is a lot for 93. An aggressive tune and/or bad gas and you'll have problems quickly.

As I said with a good tune and some luck, it IS doable. You just proved it.

I guess the real question is what does the OP mean by "will last". You think it's going to last 100,000 miles?

 

20 ish psi on a big turbo will net u 500 on 93.

 

lol now we get into an intersting conversation

will last depends on a ton of things all luck dependant

 

Turbocharger is Precision SC6162SP .63 A/R .....
1000cc injector and AEM Standalone

 

Nope. It won't make 500whp with this choky turbo. I think you will have some overheating issues too

 

why do you think he will have over heating issues????

 

Sorry.
he is going to have severe local overheating issue not entire engine or gaguge reading overheating. Just good detonations.

 

What 'choky turbo'? ^^^ agreed... What does the power level have to do with the cooling system?

 

Sorry, i mean hot spots, overheated spots

 

Turbo is to small for it to work on 93 oct
Boost by rpm to keep torque low and water/meth injection to cool the charge at high psi and it just might make the number.

Bigger turbo will make it easier, think big t3t67 or small gt40 and 10000+rpm!

 

What is the idea to put a larger turbo? To reduce pressure cylinders right?


I can buy Precision PT6776HPS 67mm turbo .63 A/R for 750hp ....

A good variant is it you think?

My head is fully build with valvetrain , retainers , valves and cam Supertech for 9000++ rpm safety

 

bigger turbine is better flow so less backpressure and more breath up top (coupled to a decent mani)

bigger compressor is more efficient delivery at same psi
think difference 20psi t25 and 20psi GT42R, that's the difference between 350whp and 600+

 

You will hear and buy Precision Billet 6765 and what will be done with engine
