hey guys, im thinking about buying a civic and later down the track boosting it.
im deciding between a b16a or a b18c. . do you guys think it would be better to just buy a vti-r with b16a and then boosting it or buying aEG Gli and then putting in a b18c and then boosting it. and if i bought the vti-r and decide to go b18c would that be wasting money or can i make some money back from selling the b16a and buying a b18c?
i dun want to buythe vti-r and then wanting a b18c and wasting money..
is there gonna be much difference in output from the b16a and b18c ?
suggestions and reccomendations please.
im pretty new to this. any help would be appreciated

 

It's all a matter of preference and what u are looking for...the b16a is prob putting down 160hp with high compression pistons while the b18c is putting down 180hp. the real main difference is in the torque. the b18, i would be a safer bet on boosting straight up. it can handle more boost because the compression ratio is lower than that of the b16. I'm kinda in the predicament myself, looking to boost an engine so i know what u'r going through right now.

Yeah...i read that article but i'm talking more boost straight up and being able to still be a daily driver. I'm not sure the boost but a stock gsr turbocharged can handle 350hp as a daily driver without stressing the engine too much. Full race's turbo kit states this, of course you do have to do some calculations but in the end it comes out to around 350hp on a stock engine and a bolt on kit. I'm pretty sure u'd really need to think about boosting a b16a with high compression pistons and at that kind of boost your bound to blow the engine.

 

could someone with experiance just gime some stats to help me make up my mind ? say boosting the vti-r with b16a how much power (kw)can i get out of it safely as a daily driver without having problems. (assuming its well tuned) and say the engine has done 130,000 does that seem a lot of k's to boost ? i know i need to do research and stuff.. but just want to kinda make up my mind and then concentrating researching on one thing.

 

If you want 350 whp on a civic, you need to do some internals. You also need suspension work.
The thing is, if you wanna do 350whp, you should invest some internals cause spending the money you would to make 350whp, you obviously want it to be around a while.

 

B16- high compression, low torque. great motor. is well suited to "low" budget builds (yeah, I know, its not cheap. im comparing it to other b motors.) takes well to mods. Good for FI, but keep boost levels low, as CR is too high for decent boost. early ones had cable trannys, later ones went to hydraulic.

B18 non-vtec-a little cheaper than b16. great torque, mediocre HP. good potential. decent for boost, lower CR than vtec motors, allows for higher boost levels, but similar power numbers.

B20 non-vtec- good motor, pretty cheap. b20b is good for boost, low CR. b20z has higher compression, good hp and great torque on both motors. possible to go cr-vtec, but has issues with piston-to-valve clearence. more feasible than ls-vtec as Honda doesnt offer another b-series 2L vtec. even non-vtec has great swap potential. has thin cylinder walls, might become a problem at high boost levels. and crv tranny will NOT bolt up to a civic. must use other b-series transaxle.

B18c1- great torque, great HP. good all-around motor. takes to mods very well. compared to the b16, its everything the 1.6 isnt. good throttle response, good low end torque. high compression though. keep boost low. even with low boost, some impressive numbers should be possible. has different cylinder head design than the other b-series vtecs. has dual runner intake system, which switchs runner length with rpm. wasnt as great as everyone thought it would be. has higher compression than other B-heads, due to large quench pads in combution chamber. these also help fend off detonation, but that might be too advanced for this post, so ill leave it at that. only drawback is cost. swaps go for about 50% more than a b16 swap.

B16b-better torque than b16a, but still nothing substantial. crazy top-end power. probably the craziest 1.6 in any production car. too expensive to justify, unless you are building a type r replica, and are looking to get some credit for that. its a great motor for NA, insane compression, way too high for boost, i know its possible, but why? you can do better for less money. can run 2-2.5 times the cost of a B16a swap. for the money, go with a gsr. the only thing a CTR motor (civic type r) has over gsr, is a little hp, and a lot of bling. comes with lsd trans.

B18c5- the Holy Grail of the Bs. good low end torque, great high end power. compression is too high for much boost. a beast in a lightweight civic. good for NA drag racing and auto-cross. comes with lsd trans. way too expensive for most people. if you get one for a good price, take it. can run 2.5-3 times the price of a B16a2 swap. most parts are interchangeable with other motors, allowing for some crazy combos.

THANK YOU SACICONS

 

Thanks for all that infomation much apopreciated. one question that wasnt answered was say boosting a b16a for a every day driver how much whp or kw can i get out of it without it having much problems. and also what needs to be considered when boosting engines. example high k's on the engine? does that matter ?
