D16 or a B16a
 

Should I just do up my d16 or should i swap it for a b16a i wanna make pretty much a road legal race car. what should I do?

lol that funny.... hahahahahaha
but seriously go with a b16a more parts, easy swap... d16z6 is a good motor and takes boost well but has jus about the worse gear ratios

b16a2, or check out B18's

Although I love the d-series motor, it will be hard to use it in a race car. It gets really hard making more power after 300hp.
A b16 on the other hand is dohc, so its not as limited and the potential is higher. The thing that I hate about the b16 is the fact that its a useless swap over a d16. You get 30 more horses, and 1000 extra rpm's. The torque stays the same. For $2500 that doesnt seem worth it to me. I would prefer to work on my d16 for that money. As a matter of fact, I could probably get my d16 to around 250whp with $3000.
If your really looking to build a race car, I would consider a b18. Preferably a gsr. It's a great base, and there are a ton of options. But thats if your seriously considering a race car.

Personaly i would go with a b18a1 lots you can do eg v-tech double over head cams, i have made a planed to make 230-250hp with just internals no turbo any ways that my opinion

boost ur d16 put a d15 vtec head. its a light engine.

Sorry but I'm gonna have to correct this.

The b18a1 comes in the ls/gs/rs integras from 1990-1993. It makes 130hp and 120 lb/ft of torque. And it does not have VTEC.
If your planning to make 250hp from this engine in N/A form, be prepared to spend around $5000.

There is a great way you can make power with this motor though. Actually this applies to both b18a and b18b. Use the bottom end of a b18a or b, and the head of a b16. You get whats known as a ls-vtec engine, its a frankenstein motor that allows you to keep 1.8L of displacement, a DOHC, and you have vtec. This setup has been proven to make about 180hp and 160lb/ft of torque. In order to properly build an LS-Vtec, your going to have to spend around $3500 though. You might as well just get a b18c.

The best thing b18a and b18b engines are good for is boost. They have low compression, decent displacement, and are fairly strong. I would expect to see around 250hp at 10psi on a nice t3.

Thanks for the tips i was saying that you could put a v-tec head on it. And i was planning to plain the head down to make more commpression and yes i im prepared to spend around 5000 grand and will the b18c fit in mostly all hondas would i have to get ne engine mount to fit it in? thanks

I'd just get the engine mounts from hasport. If you check out their site you will find what you need, because it varies depending what car you have, and what engine you want to put in.

If your planning on making an lsvtec, your compression ratio should be about 10.0:1. To up their compression on ls-vtec's, what a lot of guys do is run p72 pistons off a jdm b18c1, or the p73 usdm b18c5 pistons. p72 pistons will put you at about 11.1:1 compression, and p73 at 11.6:1 compression.

Personally I'd just stick with p72's since they are easier to find, and if you want to up the compression after that, I'd switch to 2 or 1 layer thick headgaskets.

thanks and if i want and i do wanna make more compression ill plain the head down to make more compression but thanks for the help hasport has what i want to its awsome thanks again

Ya no problem, just be careful to not up your compression too high.
