ls or b16?

[rex oner]

well i have been into the import thing for 3 or so years and used my same dx motor in my crx and *tried* to beef it up.. it has caused me to much time to try to keep ...

so now i want to run with the big boys and get out of the high 15's
i wanna go ls non vtec or b16 ... and money is a bit of an issue i found a shop tho put a whole b16 swap in my car for 2,200-2,600 and an ls for around 1,800-2,000 depending on how cheap they get the motors

if i go ls.. i will go ls/vtec later when money is there...

is it worth th ls.. and the hassle for ls vtec later...
or suck it up and pay for a b16.. and info will help?
or if some one is selling one of the two motors tell me

-thanks

iv got a friend thats running high 14s and all he has is a jdm b16a and spoon cam shafts , pistons and NOS.
good luck

The big question is, are you going turbo or all-motor?
LS/VTEC is usually unreliable, it costs WAY too much to get it done right. You would actually be better off buying a B18C1 than doing ls/VTEC.

id go with the ls me and my bros have 3 hondas all with ls motors no vtec n there reliable we had no problems since the motors been in i have a 93 cx bubble with a 96 ls motor gsr tranny gsr head n gsr cpu and i beat the new 350z he had bout 50 to 60mph on me i hit it an cought right up 2 him he couldnt see me till i got to the toll both cuz i had a packed car n he was by himself.... n it wasnt a stock 350z he had a turbo kit n a exhuast from what i know.. i see him alot butt try not 2 let him know it was me im not tryin 2 get my car robbed

Umm, no. A turbo 350Z would be putting out about 400 HP. Your 142HP LS swap isn't going to even touch a stock 350z which has 289 HP. Trust me he wasn't trying at all.
Not that I'm trying to knock the LS engine, I think it's a sweet engine and all, but thats just rediculous.

well, he does have LSVTEC and less weight, but I dont believe it either.

No he said NO VTEC!

[94tegRS]

oh, I just read the GSR head and GSR ECU. is there much of a benefit of putting on a DOHC VTEC head and a VTEC ECU without actually enabling vtec?

guess I better pay more attention next time.

Okay, first off, a 96 ls with a GSR head, tranny and ecu, and no vtec??? either thats a) a typo, b) a lie, or c) why the hell would you pay to put in all gsr expect the bottom end, which would be the only ls left, and not enable the vtec???

okay, now that I finished with that, here's my I say go with the LS. I have an LS and I love it. The added torque of the LS versus the B16 is worth in IMO. The LS tranny's longer gear ratios is prefactly suited for turbo apps, and the LS bottom end can handle more boost on stock internals than a B16, some ppl say it can handle 12 psi, you would go more than 8 on a B16. ( I'd peronally stick with 8 period on stock internals). Anyways, if you want all motor, the b16 is a good choice, if you want to turbo it, go ls.I personally say, go with the LS and turbo it up. forget the b16, the h22, and the ls/vtec..the ls/vtec is too unreliable. Put that money instead eventually to building up the internals so you can turn up the boost really high. You'd be faster on an LS done right, built-up, running say, 20psi, than an LS/vtec. Plsu you can always turn down the boost to save then engine when not at the track. Sorry my post kinda sucks. I am usually more informative, plus my posts are usually clearer. But it's 7am and I haven't slept yet, so that could be why,

I completely agree. But 12 PSI on a B18B1 is a ''safe'' number for that engine. I've seen 15 PSI boosted on stock internals. The usual numbers are: 12 PSI one the stock rods, 12 PSI on the stock pistons, and 14-15 on the stock cylinder sleeves. So just replacing the rods/pistons is stupid because you just spent a grand to be able to run 3 more PSI boost. So replacing the sleeves you could run 20 easily, and that makes for about a 300 HP B18B1. Of course that includes other mods like exhaust and ignition and tuning.

I know the B18B1 can handle 12psi fine, I just haven't personally seen it done, or talked to many who have. I guess my felling is I'd tone it down until I was racing it. But you are correct, 12 psi is a safe number on the LS. I guess my comment of I would go 8psi and be safe was for the street when not racing, I'd turn it up for the track. Butr yuou are correct, you'll be fine running 12 all the time. Also, yea, if he can afford it, like I was saying, build the internals up, new stronger pistons and rods, put in new sleeves and close the deck. Thats a 20-25psi engine. Easily 300hp, like you said. Plus at 12 psi, your still well over 200hp. Thats actually my plans, but having to pay for college has put them on hold for a bit. I think my 8psi comment about being safe may have been a product of it being 7am and I hadn't slept yet, lol. I'm suprised my post was that clear, considering how tired I was.

Oh yeah I see what you're sayin. 8 PSI for daily driving, 12 PSI at the track. With 12 PSI he should be doing atleast 250 to the crank, and 220 to the wheels.
