Which B series engine is best for a turbo application? I want to run some low boost until i can get the money together to do some internal work to crank up the boost. Would the B18C1 be best and will i have much trouble droppin it into a 94 Civic sedan

: I want to go fast

And not to be overtakin by fake ass evo lancers

As much as I want to say b16b, I will have to say that the b18b1, or older b18a1 from the lower model tegs (ls,rs,gs,se) is good for boost. The compression is lower then in the b-series vtecs therefore you could boost a little more on stock compression than on a stock compression GSR motor. The reason I say this is because the Dohc VTEC motors are built on high compression for the top end power of the vtec, if you would want to run some serious power out of the turbo you would need to lower the compression of that motor whos whole purpose in the first place was to be a high compression motor for top end power. If stock block is what you want then go for the LS. That's my $0.02

I do agree with you, the B18A-B motors are more suited to FI because they demand less tuning to get power right out of the box, HOWEVER, it also means you will make LESS power with the same amount of boost on a B18B than on a B16 because of the lower compression. If you dont want to spend time to tune the car, it is better for you to hook up a B18A-B. If you want real power go B18C or B16A-B and spend the 300$ on dyno than you'll smoke everything you want.

my .02 cents...

it comes to money, for a tuner looking to be on a tight budget i suggest the b18b, its a cheaper block and the parts are cheaper, how many ls tegs do you see on the road. the potential may be higher in a b18c, but its alot more expensive than the b18b. a full gsr swap is going to run at least 4000, an ls swap with drag turbo is gonna be in the 4000 neighborhood.

The B18C seems to one of the more easier swaps to get a hold of here in Australia so i was thinking that would be my choice. But im new to the 4cyl seen so any information would greatly help, cheerz

Ive got the D16z6 in my civic at the moment and it just seems slow as compared to my peice of crap six cyl that i just gave the boot! Can i get any decent power out of the d16z6 with a turbo or should i just start with another engine?

There are some d16 in my area running 12s on slicks and 13s on street tires. It all comes down to whether you wont to work with what you have or not, but more importantly money. If money is no option go for the b18c since you said those are readily available where you are located. Now if you are on a budget, the LS swap is a good way to go for a little boost, which would probably run you around 4000+ for the swap and turbo. Now if you want to keep the sohc, then I would suggest the F-max kit. With a thicker head gasket on the SOHC, you can produce around 13psi on stock internals which isn't that bad considering you didnt swap the motor, and daved a little there, only downfall is the kit itself is 3300+ at some places, but in my opinion is hella worth it. I myself am going this route real soon, and if you talk to a couple people on this board (Red Fox, or Jay D. Em) they could tell you their take on this kit since both of them run it. Red Fox runs it on a d16y8, and Jay D. Em runs it on a b18c1. Look them up and maybe hit them with a PM, if you really want some feedback on this kit.

it would fit in a civic sedan

Yes money is always a problem, Especialy here in Australia where they charge some big $$$ for everything but if it takes a swap to get a quick reliable engine than im willing to save for a year or so to achieve what i want. I heard that boosting on a D16Z6 could be a problem since the conrods smash themselves to pieces after running in a boosted inviroment for a while, i read that this happened to one guy three times over two years! I couldnt afford to keep fixing my engine all the time so thats why i was a bit concerned about boosting the D series. Is there any way around this problem? Maybe this guy was running alot of boost, possible? Reading this guys sob story is what made me consider a swap, Thoughts? I havnt heard of a f-max kit, have they been around long? is there a site i can see one? Thanx

you can have the d16 rebuilt and boost high boost levels. F-max is a good company with a complete turbo kit but it is expensive.

If you only want to boost low for now until you can save up for a rebuild, you might as well go with the B18C.
