I will make project with stock b16a2 sleeves with turbo gt3076r and I am interested how HP can safetly spend the stock block that will be a guard block between cylinders or pins? In my country, Bulgaria has a fuel with 100 octane and the car will be driven only by such ......

My expectations and desires are ~ 450 whp of ~1.5-1.7 bar pressure ....

 

450whp on a stock engine regardless of fuel type is rather risky and is not recommended as a power goal for daily driving use..The stock block regardless of turbo and amount of boost used can take only about 350-400whp. After that, the motor will seriously be fatigued. A block guard with a stock block is not going to help you much, regardless of the pressure.

Short answer: It CAN work, but tuning needs to be spot on, and don't expect too much longevity as you increase abuse.

 

If you want 450whp and want it to last, at least get pistons and rods

 

what kind of psi?

 

He said about 1.7 bar which is around 24 psi. Psi isn't what kills an engine, it is horsepower that kills an engine. With a great tune, 450whp is very do-able. There have been 600+whp stock b16s but I highly doubt that they lasted as long as you would like yours to. Save the money for the block guard and at least get a set of pistons and rods. If it were my car on 100 octane, I would shoot for 400. That is plenty for the street in my opinion and you will have a lot less to worry about.

 

100 octane? wow. Is it the same octane rating system as ours?

 

So things have been :
Pistons - CP 9.1
Rods - Eagle
ACL Race bearings
ARP bolts everywhere
750cc injectors
255l wallbro fuel pump
Camshafts are stock only will have valvetrain and retainers Supertech to no problems in 9000rpm

My idea was that for the 450whp to use Darton sleeves ... ??

 

If you are going to spend the money on sleeving a block, you might as well start off using a GSR block, IMO.

 

With 100 ocatane you should run higher than 9:1. Go 9.5 or 10:1. Also, get 1000cc injectors. They cost the same and you'll need the extra room. You could keep the stock sleeves but i'd recommend updrading them. It depends what your budget is...

 

These are photos of b20 stock sleeves made with pins and now makes 397whp on every day without problems.
If you use this option, would it not be better than blockguard for ~400-420 whp .....
In your B20 block has a stronger or equal to b16 ......

 

I have never seen that. I would not feel safe shaving the sleeves like that. A blockguard reinforces the sleeves without damaging them

 

I think endyne had a similar sleeve reinforcement style, with the exception of the pins being drilled into the side of the block.

Block posts is what they call them.

Look I see these threads daily it seems about stock sleeves. If you want to make big power don't half-*** it.

Sure people have made big numbers on stock sleeves, hell even on all OEM blocks with some head studs but who gives a ****. How long did it last.

Personally I would sleeve it. Or you could be like 90% of the hicks around here and never drive there cars because they are always broken.

 

The 100 octane fuel in Bulgaria is a RON rating so his 100 octane, like here in Japan, is actually about 95 AKI (US). The US AKI rating is (RON + MON)/2 but the easiest way to convert RON to AKI is RON X 0.95.

Like many people have mentioned before: upgrade your pistons, rods, head studs so you'll have longevity and use 1000cc injectors so you will have some breathing room. If you have a reputable machine shop near you, you can purchase aftermarket sleeves and have the machine shop install them for you. The best method is to send your block to a reputable company/shop that deals with Honda engines on a regular basis.

What ECU will be used to control this setup?
What exhaust? Custom 3" (76mm)
What tires? 450hp is worthless if you are running on brick hard tires or all weather commuters.
Is this a strictly street car?
Will you be doing circuit or drag racing?

 

Not , really 100 octane fuel for us as your 95
For now I close with Engine Block Post Kits because it seems to me most certainly to change without sleeves .....
ECU will be AEM, exhaust of 76 mm and the tires are 225/40/17 Toyo R888

Coming Soon Dino chart with 400+ whp and 11sec 1/4 mile with terminal ~ 208-210 kmh
