Ok, i plan on saving my money to get a full engine swap from my 99 Civic EX with the 160hp SI engine. But, its only 30 more horses more than my engine now, less with my mods. Will I notice a difference at all in speed? I mean, is this worth the money?

fa sho!>........dont underestimate the DOHC. it pulls in a totally different way than the D16. plus with all the aftermarket availability, you'll be able to propell the B-series to levels twice as powerfull as the D. puttin' money towards any B-series motor is a worth-your-wild investment!
I agree...I've got both an 99 EX and 00 Si, and that Si pulls unbelievably compared to the D. And yes availability and quality is much better for the Si. But to be honest with you, you may want to look at getting an even better engine swap...since you ARE spending that much money you might as well go all out and get the best!
true true......try a GSR....they are kinda popular and the price isnt too high. check on total-boost.com or maybe hmotorsonline.com. they have some really good deals. persoanlly im all for the illusive B18C. im just into the whole type R thing when it comes to power.matts2ksi said:
there really isnt a 'best' motor to swap....it all depends on the builder and what he/she wants out of the motor. Im more of a power hungry type of guy so i look at high HP motors like B18C or H22A......some people like to build a less powerfull, more solid base motor like a B16A2 or B18C1. Tuning is all about the driver.......he/she needs only to make up their mindmatts2ksi said:
Its all about whatyou want for boost GSR is good, for all motor Type R is best for just the potential of haveing a fast car a b16 is fine there are many things you can do to it but i would agree with what someone else said think ahead if yo uwant boost get a motor better setup for boost, basically a motor with lower compression if you want all motor get a b18c there are some on jspecautosports.com.
SI are definitly faster and you can feel it too, but what are you all planning on doing? and how much money you willing to spend? That all should depend
30hp will feel like night and day. To answer your question it takes just a little more info. What are you goals with your car, how much do you want to spend. If you want to go fast there are many ways to achieve this. All depends on how much money you want to spend, the variations are almost endless. I will get flammed for this but you can mod your D-series for cheap, parts are dirt cheap find them local used I/H/E cam, ect you can also go junk yard turbo or even a full turbo setup like greddy, Nitrous on the D-series, B16a is always good, B18c1 as everyone said is nice, B18c5 if your a baller, also frankinstein motors LS/Vtec or B20 vtec. What do you want to achieve and how much do you want to spend is the name of the game when it comes to building any car.
also, there is more to an engine than just peak horsepower. the b-series will pull better throughout the entire rpm range. plus its a better platform to begin with. you have to dump money into the d-series just to get near the stock output of a b
Not trying to be a jerk, but from what it sounds like you dont know much about motors, and if I interpreted what you wrote correctly you're saying the SI engine will put out less hp compared to your current d16 setup??? I highly doubt it. IF you've dropped enough money into the d16 without a turbo to make it do that then stick with the d16. Despite what you may have heard I/H/E on your D16 will not give you 50hpslimddozen said:
maybe like 15whp if you're lucky which leaves you at 120whp on your d16 compared to the still 135 or 140 (im not sure) whp on the stock SI. good luck tho 8) Oh yeah I'd get the B16 if I were you if you have the money
You will notice a difference in speed and a difference in V-tec reactions, however, 30hp isnt night and day-----200hp would be night and day. Put a 55 shot on your modestly modded D and determine if making the transition would be worth your time and money. Spending $500.00 is way better than being out $4k, view my comparison in prices and hp below.
A lot safer, to swap in a B series, I'm imagining nothing could ever go wrong with this motor, its indestructible!!!
I have this thing with dollar to horsepower ratio.
I have to ask, who can really justify spending say $3000.00 for say 30hp gain??? Then gain modest amounts of hp through purchasing bolt ons that include I/H/E creating say a well respected 30hp more for another $1000.00??? (considering you do the swap for $3k and other work yourself)
$3k / 30hp = $100.00 per 1 horsepower --------------------swap
$1k / 30hp = $33.00 per 1 horsepower --------------------bolt ons
Now your out $4,000.00 and gained 60hp @ $67.00 per 1 horsepower -----not really a deal if you think about it.
Then say what everyone says: add a turbo to your B16 and you got mad horsepower.
$3k / 100hp = $30.00 per 1 horsepower -----------------turbo kit for B16
Now your out $7k and gained 160hp @ $44.00 per 1 horsepower -------still not a deal, but hey you spent $7,000.00 and now have I think its more like 320chp and 255whp, we'll use those numbers
================================================== ======================
Or keep your D series for example. Stock having 130chp or 105whp.
Spend $3,000.000 on a turbo kit and $1000.00 on an exhaust system, fuel pump, oil pump, water pump, fuel filter, new head bolts, and timing belt. (Considering you do the work yourself also)
Turbo kit gaining RELIABLE hp @ 205whp or an actual gain of 100hp
Exhaust bolt on gaining a respectable 10hp.
$3k / 100hp = $30.00 per 1 horsepower -------------turbo kit
$1k (using the $1k for full example purposes) / 10hp = $100.00 per 1 horsepower -exhaust
Now your out $4k and gained 110hp @ $36.00 per 1 horsepower ------still no deal for $ to hp ratios. However, you spent $4,000.00 and now have 240chp or 210whp.
--------->(WTF, now your @ 176whp w/ a B and $4k)<-----------------------
Now considering you are 80-100 # lighter with the D engine vs. the B engine this almost makes up for that 45whp that you don't gain saving you $3,000.00. (This being a comparison between the B @ $7k and the D @ $4k.)
Then take that $3,000.00 you managed to save and build your block and btm end and put a complete head job on giving you another 100chp making your new total now 290whp. In turn making your $7,000.00 investment $33.00 per 1 horsepower still being reliable by adding a dual stage boost controller running 12psi daily and 18-20psi when you need it to kick the s**t out of that modestly modded B series for the same cost factor.
================================================================
So thats $4k B series power @ 176whp and D series power @ 210whp, and
thats $7k B series power @ 255whp and D series power @ 290whp, am I missing something here? Like where the justification is with this swap!?!
Could someone justify this to me!!!!!!!!
================================================== ======================
Then you get into the car down time which is a whole other story.

Just sell the damn ex and buy an Si, not only will you have a car with more horsepower but you will get all extras the Si offers.
......I would swap a b18c1 or b18c5 if you gonna swap.....you will notice the diference then
b16 engines are made for high rev and long lasting....it might not be the most pwoerful..but its the best setup for the b series motors
B16B! FOO. get civic supremacy!
