"Why should I swap my D series out?"

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 40hp 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 / 40hp = $75.00 per 1 horsepower --------------------swap
$1k / 30hp = $33.00 per 1 horsepower --------------------bolt ons

Now your out $4,000.00 and gained 70hp @ $57.00 per 1 horsepower -----not really a deal if you think about it.

Then say what everyone says: add a turbo to your B18c and you got mad horsepower.

$3k / 100hp = $30.00 per 1 horsepower -----------------turbo kit for B18c

Now your out $7k and gained 170hp @ $41.00 per 1 horsepower -------still not a deal, but hey you spent $7,000.00 and now have 300 crank horsepower or 255 wheel horsepower.

=============================================
Or keep your D/B series for example purposes I will use the D. Have 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 / 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.

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.

Or use that $3,000.00 to build your block and btm end and put a complete head job on giving you another 100hp. 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 shit out of that modestly modded B series for the same cost factor.

Could someone justify this to me!!!!!!!!
==============================================

Then you get into the car down time which is a whole other story.

originally stated by ben: "here's the way I look at it... why push your d engine to give you every hp it'll give you when you can just swap it out with a b engine, not work the engine as hard and get the same hp! longer engine life if you swap."

A: true, well not really the same hp as I compared that out for you. But I'll do it again since you didnt quite catch it the first time: 160chp stock B16 + 70hp gain taking you to 230chp or 184whp on $4k. 130chp stock D16y8 + 100 + 10 gain taking you to 240chp or 192whp on the same $4k. Considering you are 80-100 # lighter with the D engine vs. the B engine and have a slight gain of 8 hp or the amount of a good I/H/E put on the B you will most likely kill the B in the end.
You have more hp and less weight, tell me again how exactly you plan to beat the D for the same cost factor...................
==============================================

again originally stated by ben: "yes but for that same 3k I would get a b18c1 (and yes, I see them sell for 3k all the time) I got 102hp in my eg so I'd get about a 83hp gain going with the gsr engine."


This is true, 83hp giving you a total of 185chp or 148whp. Wow, yeha, you gained modest horsepower for $3k. Lets do a comparison for you as well:

$3k / 83hp = $36.00 per 1 horsepower

add I/H/E spending another $1k and adding that same 30hp, giving you a total now of 215chp or 172whp on your B. Now your out the same $4k as my other comparison and $36.00 per 1 horsepower. You still SHOULD change the oil pump, water pump, timing belt, fuel filter with a swap spending another $600.00 taking you to $41.00 per 1 horsepower. This is all assuming you did the swap yourself!!! Did you??? If not I can figure that out for you to, about $800.00 for the entire swap, bringing your total to $5400.00 and changing your power to $ ratio to $48.00 per 1 horsepower.

or

D series stock w/ Turbo kit gaining RELIABLE hp @ 205whp or an actual gain of 100hp
Exhaust (along with all the necessarys) bolt on gaining a respectable 10hp.

==============================================

Or forget about getting the I/H/E as you already spent $3k on your motor swap gaining 83hp giving you this: $36.00 per 1 horsepower. Giving you civic now 180chp or 144whp.

Or comparing to the $3k spent on your B to the $3k spent on the D adding hp to 250chp and 200whp.

Now your B18c1 is @ 144whp and the D16y8 is @ 200whp................D power baby!!!
==============================================

I'll break that down for you:

$4k on the B18c1 gaining 113hp @ a cost of $36.00 per 1 horsepower; 215chp or 172whp
+80# weight gain

$4k on a D16y_ gaining 110hp @ a cost of $36.00 per 1 horsepower; 240chp or 210whp
no weight gain
==============================================

I guess I'm still confused as to where you justified swapping. Please explain..............
