Hello,
I want to build my engine. I have a Honda L15B7 Engine. It’s a small 1.5 Litler engine.
My plan is to install Pistons, Rods, and Sleeves in the engine.
I really like this car. (10thgen Civic Si Coupe). I like the design of the coupe, and I don’t feel like buying a Type R.
I’ve seen these engines pushing around 300Whp with bolt-ons. But I know my engine is going to blow out if I do so. That’s why I want to build the bottom end of this engine with stronger components.
Currently I have a stock engine, it’s pushing around 23 psi of boost. The engine is healthy, has around 130K miles. I have no issues with it in its current state. No oil leaks, no issues. Seems to hold to all the abuse. I’m well aware this isn’t going to last forever though.
I’ve been doing research for the past 3 months on components. I was thinking on building the engine to stock bore. Using sleeves since this block is an open-deck design. This will require me to remove the stock cylinder liners.
The top of the sleeves close the deck, and only have the necessary coolant passages. I believe this will improve the longevity of my head gasket since these boosted engines tend have higher stress and combustion pressures. The cylinder tends to warp under pressure which leads to head gasket failure.
Here is an image of the aftermarket sleeves for reference.
Other than the sleeves the rods and pistons are going to be sock bore and stroke.
I would be cool if someone could help me, or even pay to teach me how to do all this process.
Boring the liners, decking the block and head, and also boring and honing the cylinder walls.
I can supply the tools needed for the CNC mills, or end mill bits if needed. I’m really interested in this process. Or even if it’s possible with the tools available in the machine shop.
Thanks
