Turbo LS vs. Turbo LS/V-TEC
IM TURNING THIS THREAD INTO YOUR LS TURBO AND LS VTEC TURBO BUILDS. SHOW ME WHAT YOU GUYS GOT HAVE. POST YOUR DYNO NUMBERS IF YOU CAN AND LIST OF MODS. Im not trying to copy the turbo ls post. This is for my own reference i just wanna see what you guys got and what these setups put out. THANKS!

Re: Turbo LS vs. Turbo LS/V-TEC
the "vtec option" isnt a big deal. Its just a solenoid thing that you hook up to the outside of the head. Your best option seems to be to fit the vtec onto the ls head.

Re: Turbo LS vs. Turbo LS/V-TEC
Are you serious. Thats the dumbest thing that I have ever heard. Its more than just the vtec solenoid. The b16 head flows way better than the ls head. You would have to build the ls head just to flow equal to a stock b16 head. The cam profile is more agressive on the b16 head obviously so it will make more power up top in the rpm range. There is no way you can just slap a vtec solenoid on an ls head. I guess this is where honda-tech has gone

Re: Turbo LS vs. Turbo LS/V-TEC
wow please never give anyone advice again. Anyway what kind of power are you looking to make? simple answer is the vtec head will make more power, do you need it to hit 300hp on a stock block no, but it will take less boost to do it with the vtec head

Just WOW. And he has over 2,000 posts.
Maybe I can put a V8 badge on my car so it will have 8 cylinders.
As boostedeg302 explained, the B16 head flows much better than the stock LS. Not on will you benefit on the flow, but you also will reap big gains when the vtec activates and your valves open up more for the higher RPM range. You also will have a lot more cam choices to chose from for the vtec head.

Re: Turbo LS vs. Turbo LS/V-TEC
maybe this guy is on to something, all this time everyone has been going threw all the work of a head swap and paying for a lsvtec kit and all we had to do was duck tape a vtec solenoid to the head.

Re: Turbo LS vs. Turbo LS/V-TEC
thanks guys, now im going with the GT35r Garrett turbo. I know its turbo that spools late in the powerband so i want to go with either GSR or ITR cams because of the more aggressive profile and the extended RPM range and want to make full use and get the full effecincy out of the turbo. Is this a good idea, and also how much of a build should I go with to get around 400 hp out of this turbo, because I heard this turbo on stock internals pushes around 350hp, once again thanks guys and all opinions appreciated

Re: Turbo LS vs. Turbo LS/V-TEC
i make 360 on 12 psi with a 35r with a .63 hot site. Spool is 5500 for 18 psi, 5k for 12 psi.
if you get a bigger hot side, your spool time will increase but top end will be gained
you just need eagle rods and a piston of your choice(wiesco, JE, CP, arias)
a 35r is good for around 700 with the right setup, who told you 350?

Re: Turbo LS vs. Turbo LS/V-TEC
That sounds great. I want to run at least 400 on pump gas and still want it to be pretty reliable. I don't want this setup shitting the bed six months or so down the road. And what do u mean by the "hot" side (sorry if its a dumb question) the turbine chamber or the compressor chamber??? and also whats ur suggestion on compression??? ive been advised on 9.0:1 and if so do u have an idea what kind of overall comp that'll make with the B16 head??? thanks

Re: Turbo LS vs. Turbo LS/V-TEC
make sure you pay attention to his management.... IMO if you have money for a motec than a 750$ sleeve job would give me a little piece of mind at that power level...

Re: Turbo LS vs. Turbo LS/V-TEC
Do you guys think I should go with ITR cams with the high revs they offer along with an aftermarket valvetrain. With this setup, an aftermarket IM, bigger injectors, rods, and pistons should this be reliable at about 15 lbs with the GT35r???????

Re: Turbo LS vs. Turbo LS/V-TEC
the stock b16 IM is fine if you don't want to spend the money on it.
Injectors and a fuel pump for sure. Recommend peak and hold injectors, less likely to fail.
Do some searching on your rods and pistons, I'm not an ls/vtec guy, but stock on my gsr which is about 10 to 1 comp. I made 350 whp on 10 psi.
What exhaust manifold are you going to be going with?

Re: Turbo LS vs. Turbo LS/V-TEC
That's on pump. On C16 I EASILY could've hit 400, or even with e85.
I personally have 750cc peak and holds. More reliable then saturated. If you don't already know, their is SOOOO much more you're going to have to do and read up on. Not trying to be a jerk. But their is alot of things you might be able to learn just by searching and not necesarily just asking for questions ya know? I know alot of people on here are willing to help...but a lot will flame.
For 400 whp you're going to need everything from a 3 bar map sensor, to a non ebay intercooler lol. Those are garbage and very inefficient. Do some searching in the for sale threads and see if you can snag a nice garret, pwr, or precision. You're gonna need oil lives and intercooler piping, clutch, a resistor box for the p&h injectors..the list goes on and on lol.
As far as manifold. I've been quite suprised at some of the power some of these guys are making with basic manifold all the way to the top mount like myself...depends on what you want after you do your own personal research.
