Re: D15B jdm Upgrades
I think when hes refering to the Y8 head gasket he ment the 2 layered gasket. I believe its 0.027 inches as opposed to a y8/z6 gasket- 0.037 inches. I agree with a milled head, the thinner gasket, and I/H/E the D15b would be able to put up with the B16. Dont forget there are different gens of the JDM D15b. Im assuming the OBD1 version with only 1 vtec is the one we are discusing but i believe there was a newer D15b made with 2 or 3 vtec solinoids and 2/3 stages of vtec.

Re: D15B jdm Upgrades
I recommend sohc fans to look out for 1/4 numbers listed for sohc builds located in the sohc drag times section listed in the old eg/dc faqs section, then compare them to dohc ones to have a better idea! read this aswell .http://importnut.net/theswap.htm
my friend runs 14.7-8 ish all day long in an eg dx gsr with just an intake and catback!
I ran 14.9 with an b20z nonvtec eg vx with very cheap and plain bolt-ons, both are only achieved in d series that have a very serious modification list and have a big price tag! and do remember the point of resale with a d vs b civic!

d15b is a decent engine, but its lacking some torque that the 1.6's have.

Re: D15B jdm Upgrades
building internals for 300-400 bucks?
you do realize this isnt lego? most guys were talking about labour for droping a b-series,saying the swap install would be another cost, sorry but I cant see them building the d15 internals for fairly cheap if possible at all! besides the least one (who is smart) would do to a build is hot tank, check bearing clearances, check crankshaft play, deck the block, deck the head for a flat surface,get new bearings,new rod bolts, new head studs,new pistons,new rings,a fresh hone,new w-pump,t-belt,o-pump,new seals,new gaskets,balancing the internals and obviously the assembly of all the parts plus lubricant and honda gasket maker for a proper bottom end alone!
the preperance of the bottom end alone for a 13 sec d would cost more than the 1500 you speak, unless you want to take the risk of failure in the future, besides that price doesnt even include rods(which d series are non to fail after a weak *** 200hp)
dont get me wrong Iam just trying to make my HT friends more aware of the facts just so they can be more realistic, most if not all of the N/A d15's that run 14's specially 13's are wildly built d series that by far extend to higher prices than a b swap, plus just how much cheaper do you think any part is for a d vs b, I dont think there is anything substantially cheaper performance part availble for the d over the b!

But yea, agreed... OP you're not going to get that kind of time at the track even with a fully built N/A D-series... they'll only make like 160-170WHP.

Re: D15B jdm Upgrades
there are a lot of tools in this thread. a header is not gonna get you 10 hp, neither will exhaust or intake. maybe added together, thats a small maybe

Stock internals are good for about 200whp. N/A or Turbo.
I am sorry but what you have said is not true. My 1.5 was not fully built and it made 160+whp and went 14.00 all day long. It avtually even went 13.95 with a stock block and head. Just a cam and carbs. So lets not start talking about things we know nothing about...

Re: D15B jdm Upgrades
i agree too much incorrect info 160-170whp is not tops for the d with a bisi level x cam and high compression which can easily be had from stock parts 240whp normally aspirated is possible and still costs less then a b swap and thats including valve springs etc...
also the good thing about the d is if it does blow its not the end of the world they're cheap and plentiful.

Re: D15B jdm Upgrades
there are already people who have dynoed a d15b with i/h/e geting 125-128 whp its waaaaay more than 10 ponies....stock d15b comes with 130ps/128.5 hp to the engine you get your 15% back that is pretty good a dyno run does not lie

Re: D15B jdm Upgrades
Not at all... But when people post negative/wrong information about these engines for some reason people tend to believe that negative and not the positive. Thus the reason for many people spending too much money on a swap that is really not needed. I am building another d15 now that will be pretty much "built". Same basic setup but this time with 15:1 compression, ported head. Same stock rods, same cam and carbs too. So we will see what happens. Still very economical as far as builds go.

I don't want the OP to do a swap either, I support the D-series all the way... I had just been misinformed that it wouldn't be able to make those kind of numbers N/A.

Re: D15B jdm Upgrades
whoah now... how many people do you know running 200+ whp in a n/a d series... i know of zero currently running. i know of one guy in puerto rico running a 12.7x something with around 170-180whp though. there are more and more guys bumping the 170-180 mark, but 200 is super super rare n/a.
but who cares. boost it for less than half of that 14 second B swap and have fun going mid 12's

Re: D15B jdm Upgrades
i read it in modified mag,they did a dyno pull on some car and it got like 4 or 5 hp they say when you get a better ground every thing runs smoother and throttle response is better but im still looking into where and what to use ive found a ground wire set it claims like 7 hp or so but i need to fully check it out like to see if any one did it
