I'm planning on running an LS-Vtec in my Integra. A B18B block with a B16A head. I just want to know if someone else out there has done this (cause I'm pretty sure there's tons) But I want to know how well this setup is.

 

I don't know exact gains, but some of it will depend on the cams you use. I would hope you know stock B18B1 cams wont wont, because they don't have the extra VTech lobe on the cams. I've heard the B16 head works very well with the ITR cams, but like I said I don't know exact gains. I'm curious on this subject as well, because I plan to make it the first offical mod to my car.

 

Use the search function as this topic has been cover MANY, MANY times!

 

If it has, just be kind enough to answer the guy's question. Since you've seen it so many times just answer him and get it over with.

 

forget vtec. turbo is the way to go. thats what i did.

 

ive done it several times and if you put it togther right you shouldnt have any problems. there i 1 case i heard that had a problem round here and its only because he miss shifted and put it in 1st and not 3rd (dropped a valve) i use a ls/vtec in my "street car" and im very pleased

1. His question is VERY vague.
2. a couple more months on this forum and you will understand why some people get aggravated when people dont search BEFORE asking questions.

Ignorance is bliss... a turbo'd ls/vtec is a whole lot better then a turbo ls... the vtec eng. and turbo compliment eachother.

plus there is a difference between 600 and 1000... let alone 600 and 2000-3000... some people arent capable of doing a turbo setup... head swapping is rather easy.

 

if you do the ls vtec combo, you need to strengthen the motor. that means new rod bolts and b16/gs-r rod/main bearings.. so you can rev higher. also need a vtec oil pump and water pump to handle the extra oil pressure vtec needs as well as revs. use the gs-r timing belt with the vtec pumps. make sure the head is completely secure and no leaks that may be caused by dowel pins, headgskets or watever.. this is common with ls vtecs not buit right. be sure your vtec oil line is of good quality and correctly tapped into the block and head. replace all gaskets and seals and don't skimp on things.

a common build would be:
b16 head
b18b block
gs-r transmission
p28 chipped ECU
performance clutch
b16 or ITR pistons for higher compression 10.8-11.3:1
ITR cams, and valvetrain
ITR intake manifold
OEM gasket kits
gs-r head bolts
ARP rod bolts
rehoned block for pistons
polish crank
balance rotating assembly
OEM rods resized, shotpeened for strength, and using b16 rod/main bearings
golden eagle dowel pins/vtec conversion kit.
b18b head gasket
gs-r oil/water pumps
gs-r timing belt

this would be a very decent, simple build with about 1200-1500 invested into the block, tranny is about 500-800, head runs for about 300-500, ITR cams and valvetrain $500, ITR intake manifold, $180-200, chiped ecu $100-150. your choice of intake exhaust and header, tuning $???

ls vtecs will make good power. easy 13's low 14's in a full interior full body integra for you with 170-200 whp depending on extra mods, which is about 210-230 at the fw. . and safe rev limit of 8200 rpm, and almost same reliability as stock.

good luck

You have to be kidding first of all the ls motor is almost the perfect setup for a turbo the block and bottom end are strong and the compression is just right. I have a ls and I wouldnt waste 1 dollar on the vtec swap only unless I was doing an all motor set up. I also disagree on your high 13 low 14s statement for fully dressed teg just doing vtec swap and raising the compression a bit I have h/i/e and 75 wet shot and my best time is 14.0 that was with the car stripped no hood no back seat no spare tire jacks ect. ect. I had the car dyno tuned before I raced and with the 75 shot i was putting 201hp to the wheels with 160ft tourqe sorry would have to see to beleive not saying its impossible. Also a turbo would put out almost twice the power for less money.www.uncensoredimports.com goto video mikes teg at the track.

75 shot nitrous on a stock block with IHE, is good enough for high 13's really. were you having traction problems??? what about your clutch? also you are using the LS tranny correct?

notice i told him to use at least a gs-r tranny. i said between 170-200 whp and you can run high 13's to low 14's. ok i'll be more specific, 13.8-14.3? does that sound better? thats with at least a 2.2 0-60ft time. and 2400-2500 curb weight. all i'm saying is that it IS possible.. whether or not you can hit those times is really up to you as a driver, the track conditions, and so many other variables.

if a USDM ITR can run mid 14's on 165 whp, and can run 13's slick down with a few bolt ons, and tuned.. i don't see how an ls/vtec could not. you are basically making an ITR motor minus the revs, and all the little bling details.

and the topic of this post is LSVTEC... he's not asking about a non vtec turbo setup or 74 shot NOS on a b18a/b. he's asking about LS vtec, so thats what i'm telling him about. and making sure if he's going that route that he becareful and take the proper steps to do it right..

 

tranny makes a world of difference...
