Hi, i got a red 96 dc2 gsr shell i'm building. I'm still new to hondas it's my 1st actually build. Was wondering which is better for boost and me achieve 350whp easy in my dc2 shell Ls-T or B16-T. Also already have a JDM B16a engine i'm building with a p72 head. my B16a is fresh out of the machine shop hot tanked,bead blasted, crank was micropolished, checked 4 cracks(no cracks), deglazed/honed. its going 2 be a new stock rebuild the B16a but want TQ but of course vtec head flows better then non-Vtec. NO, I don't want 2 do lsvtec don't really like hybrid engines, thank you.

 

I would boost the ls. i had two friends the LS was on an FMU, and b16 was tuned. LS stomped all over the b16, and i had another occurance of two friends, one teg had a stock ls swap and the other a stock b16 swap. it was a neck and neck race. the b16 just doesn't produce enough torque to propel anything really. In this scenario, torque is what wins the races

 

True that about the TQ but does vtec or non vtec head really matter when the turbo is spooled up when both engines are just prouding 350whp that's my plan. Plus i heard boosting a Ls is cheaper then boosting a B16a is that true if so i'll just trade my jdm B16a short block fresh out of the machine with the gsr head if that's the case. just the block is for it to be complete is missing some very minor parts. I'll just post it on the marketplace but somebody else give me their feedback too!, thank you.

 

the P75 LS head is one of the worst flowing of all the Bseries. But since your forcing air, it cuts alot of the flow characteristics.

Im non vtec and on boost and Im quite happy with it. I also have the P8R head which flows close to the B16.

Either choice has their own plus' and minus's, just do some research and figure out what route you want to go.

you can also source a P8R head for the LS. Theres good aftermarket support for use non vtec crowd.


Edit: just saw this was WHP which means 400(+) at the crank.. So better dig deep in your pocket!

Rods, pistons and maybe even sleeves. Might as well rebuild the whole engine

 

Oh don't worry i'm going forged internals and i'll build either head ls or p72 head. I know they sell aftermarket stuff for the non-vtec crowd like BC with their stage 2 N/A cams etc, tit valvetrain etc. I'm wont be going cheap with either engines when i go boost but thank you 4 your feed back bro.

 

Build the b16. You already have it. Ls heads don't flow for **** period. Just cause someone's ls beat a b16 doesn't mean **** without posting the setup. Theres a guy that went 10.14 on a stock bore stock sleeve b16.

 

SO true dude lol cause i already have it and it's almost complete, yeah i want to go 350whp stock sleeves and new stock internals wit just arp headstuds, yup vtec had better flow. Yea i seen B16s do 11 etc and maybe Ls. Okay then thank you man and i want to be different have a boosted B16a in my 96 dc2 gsr red.

 

Your not the only one to do it. My boss went high 6's in the 1/8th with a sleeved b16 in a teg. It may take a few extra psi to make the same power as compared to a 1.8 or 2.0, but why waste time n money when you got the b16. I'm building a piston n rod b16 now myself because I kept coming across good prices. I've only got a grand in a complete b16, brand new SRP pistons, and brand new eagle rods.

There's another dude on here that's built a few b16's in the high 300, low 400 range with nippon cast pistoms and arp rod bolts in the rods. Also arp headstuds are needed for sure.

 

If you aim for 350whp the ls will stomp the b16 because it will have a ton more torque. 350whp is 350whp but when it's delivered with more torque and earlier it's faster. I would run Ls with GSR trans

 

350 on stock or forged internals ? cause you said the b16 is already in the machine shop built with stock internals? then you say either motor you put will be built with forged? ls turbo with either a gsr trans or if you dont care about gas or how high your cruising on the freeway b16. i loved my ls turbo with a gsr trans. i was only at 230 whp

 

but speaking of reliability, as for a boosted DD, which one would be best? considering same whp goal range with stock internals?

 

I say B16a because what i know just because of the head and revin a ls past its stock redline it's. Also vtec head flows better of course.
sorry man new stock internals with arp headstuds all i want is 350whp DD in my 96 gsr shell which this is going to be my 1st ever project/build. Shoot it's my first B16a block but will be putting P72 head on it.
True, yeah i seen and heard guys doing that gsr trans with a ls. I actually drove one like that felt way better and faster then all Ls.

 

Oh okay nice boss!, OH i know arp headstuds are a must but thank you for telling me man. Really now sweet! don't see much B16s getting build 4 boost or even building which hey its a good engine want more TQ sleeve/bore it to 84mm etc, and yeah so did i get a deal 4 my jdm stock B16a block and minor bent valve p72 head got it for $375 off a close friend, of course i paid for it 2 go get worked on at the machine shop.

 

LS-T for sure, you want that extra torque!

 

I've had several LS boosted motors, and I loved the torque. When you put down 234whp and 210wtrq from a Honda at around on a small turbo, it makes for plenty of fun. However, I swapped to vtec and never looked back. With the same turbo setup, a stock block GSR and 6psi less I made 297.6 and 234wtrq. From there I've upgraded even further, and the gains are ever better. I say stick with the B16 since you have it, put in some 10:1ish compression pistons and have fun.

 

350whp is easy with either engine. It will take more boost to hit it with a stock LS head, but cams will fix that.

 

Whichever is cheaper.

Theyll both get the job done easily. Id say at 350 the b16 in oem spec is more reliable than ls.

 

I have to run 18psi on a "57 trim" turbo to get 349whp / 29x ft. lbs.


This is on a stock ls motor with headstuds.

They can run for a long time given you have a good tune...and it helps if you aren't a WOT all the time driver.

 

Yeah the comp will be at 10;1 if not 10:3 cause the block is going to be a new stock rebuild to oem spec but my gsr head will be built with supertech valvetrain,ferrea valves,valve seals, BC stage 2 N/A cams just want the block stock but new cause getting new main bolts,rod bolts, piston rings from majestic honda and clevite bearings. Don't have money now for forged internals but it will hold the tune shop told me and i asked guys here a stock B16a block can hold 350whp easy with a good tune, turbocharger. Thank you guys!!!
Okay then, Yea i do know B16a will get 350whp cause of the vtec etc, ls have to buy cams like BC, crower etc. B16a still winning besides i do have my jdm b16a block cleaned,ready for rebuild but i can easy go get a ls longblock off a friend.
That's what I'm saying thank you man.

 

Yeah their reliable I heard Ls turbo and asked from some dudes at the dragstrip but there you go have to put more boost while the B16a more power with less boost, No I'm not a driver that always revs the engine high, only at the strip or when i'm racing the rest I'm drive normally out of vtec. I bet it pulls wicked brah.

 

Id boost the ls...example of why
Friends b18b1. arp head studs and rod bolts, crower cams, peiced together craigslist kit using some holset turbo (dont recall which), dyno-tuned on 15lbs. 366whp & 327wtq. Using a ls open diff trans in a 1990lbs ej2 w/ 22" slicks car went 10.57 @ 133

 

True their dude TQ is where it's at but top end power from a vtec head is crazy. vtec+boost=

 

Like freakin dam. I love those number TQ is close to HP. 327wtq is 327! plus 366whp ej2 has 2 fly. Ls cheaper to build to right!?. Yes i have the B16a already but can get a Ls easy for free or for $200 off a friend.

 

top end power from a vtec head means nothing when the goal is 350whp. 350 is 350 weather its from a vtec or a nonvtec. Its not like the OP is saying i want to run 10 psi on said turbo which setup will give me more hp. he has a goal in mind and a gutless torqueless B16 will not come anywhere near to being as fast off the line as the LS will if they both have the same whp because then LS will have a ton more torque. Peak numbers are worthless if they dont have the powerband to back them up.

 

Okay then, because all i want is 350whp for now then later down the road open it up and rebuild it so i can reach higher numbers. Ok then so Ls it is because i want to be fast off the line hahaha but some TQ be fine. 1st time i'll be owning/driving a boosted B-series. So ls better powerband to back up gotcha brah, thank you. I also do like the camshafts from crower for the non-vtec heads.
