Help me decide guys! D16 or LS?
 

here's the story: i have a turboed d16y7. its running on afc and 6lbs of boost and i like it. but the motor is 190k miles old! that means there has to be some change pretty soon, but i dont have too much money. awhile back i bought forged rods and pistons for the sucker and i was planning to buy a newer d16 block to put the pistons and rods in, tune it right with uberdata, boost it around 12-15 lbs? how much power will i get out of that setup?

Anyways, recently i've been lookin at Ls motors on recycler and some are pretty cheap, around $1,000. SO that got me thinkin and now i cant decide which i want. the LS ahs more potential when i turbo it... but the cost to swap to an Ls will be worth the block and tunning that i was gonna get for my D16!!! what should i do guys?? sell my rods, pistons and get an ls and turbo it? or keep building the d16??

Re: Help me decide guys! D16 or LS?
 

its all about the D ;D

Re: Help me decide guys! D16 or LS?
 

yea but u get power a lil more effortlessly with the b18... cmon guys i need some input 12 views and 1 post?? i'm ghetto just like u guys so i want ure opinion!

Re: Help me decide guys! D16 or LS?
 

the y7 can handle alot more than 6psi as it sits...just turn the boost up and be happy with it a while longer.

Re: Help me decide guys! D16 or LS?
 

I like D cuz there just soooo easy. i mean come on, if you and a friend can lift the motor into the engine bay by hand, and still run 13's - its gotta be good.

Re: Help me decide guys! D16 or LS?
 

haha that's fucken true... anyone got a complete, nice y7 or equivalent block in socal?

Re: Help me decide guys! D16 or LS?
 

12psi in a d will get you bout 200whp, the ls will get you way more power same boost just a llil bigger turbo, you should think about what your goals are if you only intend to get to the 300hp street monster range then you will be set picking up a d16z6 or y8 from a junk yard and rebuilding the seals with yiour internals and hitting that mark with your interanls even on stock sleevs if you want more power then just go for the ls

i love d's because there ------- all over the place over here and cheap as ---- too, i just cant justify the cost of a swap and a new kit for my weak ass 200 whp goals ;D ls tourqe would own if u did decide to go that way though :P :P :P :P

Re: Help me decide guys! D16 or LS?
 

Hands down the ls swap owns the d, there guys making 300+ stock block on pump gas

Re: Help me decide guys! D16 or LS?
 

thanks guys, good points. is it reasonably possible to get an ls swap finished for about 1 grand tho?

Re: Help me decide guys! D16 or LS?
 

go turbo d. i know of 3 locally running from low 13's to low 14's on stock blocks. clutches, flywheels, engines, and transmissions all cost way less for d's than ls's.

Re: Help me decide guys! D16 or LS?
 

a built d or a ls will both get you to about 300hp. i would pick up another z6/y8 and throw the rods and pistons in it. you didn't say what turbo you are running but use the extra money to buy a bigger turbo. unless your current turbo will support close to 300

ps. torque is overrated in a fwd Honda. I break the tires loose in 3rd gear at 70mph in my 17psi turbo D <-----

Re: Help me decide guys! D16 or LS?
 

right now i'm runnign a .42 .48ar volvo turbo, its ok i guess, i'm a lil reluctant to set it to 10 psi cuz it starts spooling at around 2500 and doesnt get to 6lbs untill 3000rpm, is this normal? if i set it to 10 psi wont it takes till 5k or something? are the gains greater than the cost of lag? how many psi, approximatly will it take to get this car to 300whp? and what is the best sized turbo? i dont want specs... i can search for that but actual experience, thanks guys.

Re: Help me decide guys! D16 or LS?
 

yeah that turbo is too small for 300. a 60/63 can hit 300 but that is about the limit. this is the turbo i plan on running

Re: Help me decide guys! D16 or LS?
 

alright new turbo then. is a complete y7block with trans 78k miles for $200 bucks good?

Re: Help me decide guys! D16 or LS?
 

what wrong with the y7 you have? if it is just burning oil that should be fixed with new pistons and rods. i would just throw the pistons and rods in the current block or get a z6/y8

Re: Help me decide guys! D16 or LS?
 

i cant have much of a downtime its my daily driver and plus the 78k block would have cylinder bores that are closer to stock (my pistons) shouldnt it.

Re: Help me decide guys! D16 or LS?
 

go Ls you can always upgrade to vtec later. but its cheaper to build and maintain a d series motor

Re: Help me decide guys! D16 or LS?
 

awwww you just missed out on a complete LS swap, everything, harness, tranny, engine, axles, ecu, the homie just sold it.

But it'd rock the Y7, if you get the LS, give me the Y7 for free :y By the way, do you have the stock Y7 manifold? If so, wanna give it away or sell for really really cheap?

Re: Help me decide guys! D16 or LS?
 

which manifold the exhaust or intake?

Re: Help me decide guys! D16 or LS?
 

The D is much cheaper and with the forged internals (balanced correctly of course) you should be able to make decent power out of it on higher boost.
As everybody else said a DOHC engine is going to make more power easier just because of how much higher the head will flow. Turbo B16s are prett common around this way and deffinately give everyone a run for the money at the races. There are a few guys with turbo H22s and B18s that pretty much dominate the turbo 4cylinder scene around here.
Cost, time and gain all in consideration... I would go turbo B16 over a D any day.

I also wouldn't have gotten forged pistons without getting them oversized unless you planned on a nice set of sleeves going in or a very low milage block.

Re: Help me decide guys! D16 or LS?
 

yea i realized that afterwards, plus the deal was really good so i was in a hurry to get the pistons and rods. now i gotta find a low milage block

Re: Help me decide guys! D16 or LS?
 

I didn't read all that, but I saw 1000.00 for an LS, man your getting HOSED!

Re: Help me decide guys! D16 or LS?
 

whoops, looking for a crack free exhaust mani :y

Re: Help me decide guys! D16 or LS?
 

sorry but but do u mean by that? too much? too little?

Re: Help me decide guys! D16 or LS?
 

Too much. Around here the going rate for a B18 is 275-350 and anoud $250 for a tranny. So yeah your gettin screwed. look around and you'll find something.

Re: Help me decide guys! D16 or LS?
 

Speaking from experience, I will honestly tell you that unless youre planning to get a B18C1/C5/B16 or some hardcore ---- like that, its not worth it, I have an LS in my car right now and am going back to a D16Z6, there are many reasons for this, the first one being that stock for stock they motors are about the same, the LS may pull a bit better in 1st and 2nd with the YS1 tranny, however both engines are about the same from a roll.

My friend has a Ej1 coupe with an NA stock D16Z6 and we did a few pulls against my EG9(sedan) LS B18A1 with the LS YS1 tranny, and from a standstill I had maybe a car length on him, from a roll we would be pretty much even, both cars weigh about the same and both engins have about 280,000 on them.

Another reason I am going back to a Z6 is the weight of the engine, the LS weighs almost twice as much as a D16 after you include the intermediate shaft, the bigger tranny, axles and the DOHC head it all adds up and weighs alot more, you can definetly feel the difference in the front end after you've done the swap, the cornering gets worse, the front end feels heavy and you get alot of understeer. Now I am not planning on doing alot of autoX, but i'd like to go down to a local road course and try it instead of always going straigh. I plan to buy a nice suspension this year, maybe some Illuminas with Tein springs.

and the last reason I want to go back to the Z6 is simple, the LS swap cost me over 500 dollars after it was all said and done, this may not seem like much to you guys but I did get the engine and tranny cheap, real cheap ( I got the whole swap for $300, including the axles, ECU, harness, tranny etc. etc, it was a deal of a lifetime and will probably never happen again) the rest like mounts and bits and pieces here and there added up in the end.
Most Complete B18 LS swaps go for much much more.

If you ever break anything on a B series its A) hard to find and B) expensive.
With a Z6 you can go to a local bone yard, get a part, put it in your pocket and walk away...ok within boundries, but even if you have to pay for it, it will be cheaper, and you'll be able to find it...I dont see alot of yards with LS engines around here, most of them get checked, pulled and sold or stripped and scrapped.

For the price of an average B18 swap you can have a D16Z6 swap with a good turbo kit. sure you can put the same kit on an LS, but you just doubled what you spent, and if you break something you wont be able to just go to your local junkyard and buy a block, or a head.

Re: Help me decide guys! D16 or LS?
 

A Men... this is the ---- u guys have tried everything! now when you say the z6 do you mean the dohc? or single cam? or am i ------- up my motors here.

Re: Help me decide guys! D16 or LS?
 

z6 is the sohc vtec

Re: Help me decide guys! D16 or LS?
 

there is only a SOHC Z6...Youre thinking about the ZC which comes in both DOHC and SOHC, the SOHC ZC is pretty much a non Vtec D15B and the DOHC ZC is a D16A6 on crack.

Re: Help me decide guys! D16 or LS?
 

haha ---- thanks for clearing it up that ---- always confused me.
