D16Y7s are useless without boost. Trying to build it naturally aspirated is a waste of time and money.

About the only way to make that pos engine better is to swap a y8 intake manifold and transmission, and then boost it.

boost or swap..........to get any serious performance out of a N/A D series you have to spend BIG bucks.

apexi_rsx

u would make more power with a turbo setup then a b16,b18,or b20 swap... just my opinion

Ruben19

yep.
depending on the set up

newtron63h

as it is yes, but more displacement means more potential.......a boosted b18 or b20 has more potential than a boosted D.........it all depends how far you want to go with it.

apexi_rsx

depends some are shyty drivers and run the same times in a turbo d as they do in turbo Ls's lol. or a built D( vitara and eagle build) can make 300+ and prob cost as much as a motor swap. if u do it urself. D's a easy to build and maintain. just the transmissions suck for D series. that y7 tranny sucks as it is.

newtron63h

oh yeah there are definitely variables there, reliability, cost, potential...... a boosted D IMO has a very good balance of those. but there are other options........and there are advantages and disadvantages to each.

ya my boys shop said around 1500 for a full lsv

na d-series is only worth it in certain chassis - the advantage is decent torque and overall light weight. the reason it makes good torque is because the d has a long stroke.

if you just want some pep, get an ex/si trans, p29 pistons, a nice header (SMSP), some sort of Bisi cam (ie http://bisimoto.net/store/index.php?...products_id=36) and a GOOD tune via obd1 conversion.

or, you could plop a z6 head on there (ports flow better than y8 head), run a wild street cam...and the rest of the stuff i mentioned. all of that will get you power in the range of a stock GSR swap.

a turbo setup would be very powerful per dollar spent, but it would be expensive. doing a swap the right way, with a quality engine and proper preventive maintenance done before running the engine, etc is expensive too, and you end up with an engine that does have a high ceiling, but will require yet MORE money to make powerful. anyway, re: the turbo d, you'd have to fortify the engine with head studs, something like this - http://fjdistributors.com/product_in...roducts_id=566 and then this - http://www.go-autoworks-store.com/gotutusy1.html

a stock D series bottom end in good shape can handle 200hp just fine......and 200hp in a 2000-2200lb car can be ALOT of fun. and a D series wont need a whole lot of boost to get to 200hp.

titi_vtec

hey the y7 came with a compression of 9.3.1 is low compression, just build it, that block with that heads are the best one for it, dont put v-tec head for turbo it is not stronger that your head, so just put the intake of a y8 and rebuild it and go boost, or if you put a S40 transmition and some cams on it with headers you are going to beat a lot of v-tec, that engine is stronger for turbo dont made it v-tec you are going to run bettler

ekHatchdom0

thanks everyone. but i kinda wanted all motor cause its my daily and i know people who boost there daily and i get second thoughts! i may just get headers and chipped ecu fornow then think on it better

JasonYo

You wont get much from a y7 without boost, so your better off getting that b20 or something.

And if you do, try to get a sir tranny or soemthing with shorter gears.

newtron63h

if all you are looking for is a bit more power out of it, then I/H/E, IM, cam, and tune will definitely do that. itll have some more power....not a whole lot, but noticable, and still be a good DD. add a Z6 head for some more top end.

but if you want significantly more power......you gotta boost it.

UndisputedH22a

Hey i am in the same situation i got the Y7. I have a Dc sports 4-2-1 header,Obx hi flow cat,Full catback exhaust,ebay intake,Lowered and it makes decent DD power.I wouldnt waste my money on my y7 i got an ls going in it in a few weeks.Just because i want a little more power lol. by the way mine is a 98 cx hatch with no power steering,ac,locks,windows to power luxuries.

KstuDio

turbo or swap!!

ekHatchdom0

ya im gona be throwing mine on boost maybe next couple months if not th emiddle of summer ill pickup a ls or b20

Schister66

Mini-me Y8 head swap then save for a turbo setup. Your stock internal D is safe and reliable in the 220-240whp range with a good setup and tune. Dollar for dollar, this is the most power you're going to get. A swap will cost you as much and net about 80whp less...

Lowkey12

Y8 manifold, port for ls throttle body, 10lb flywheel, underdrive pully, ex tranny, tri-y header, and a big delta cam, possibly port the head. That mite make it more fun but in all honesty...depending what you wanna do with the car....boost is your answer and building a small set up isnt that bad. your rods are your weakest link on your motor- set of H-beams and you have solved most of the problem..shim the oil pump to!!.
