is an integra Ls/vtec just as fast as a GSR?

the gsr has about i think 174 hp....how much hp would a ls/vtec have?

like 140hp, and no they the GSR is MUCH faster

First thing first. U can't go based on numbers of whp.I've had only integras. And each 1 different. I had an 86 RS with a JDM ZC. Then a 96 ls/vtec partially built. Then a 95 b18 turbo. Which I swapped 2 a b20 now. I gotta admit. 4 allmotor. Ls/vtec is da way 2 go hands down. All over a gsr. Of course tuning is a must 2 make an ultimate difference. Each vehilcle is unique in its own way Can't really say if u haven't 1.

whoever says a LS/VTEC is unreliable is totally misinformed. What happens is people skimp when building them and THAT causes the problems. The biggest things people skimp on are not really that expensive, but they do it anyway. First people try to run the LS (B18B) water pump, this pump has 19 teeth, when you need the GSR water pump that has 22 teeth. This allows better cooling at the higher RPM range where the VTEC allows the engine to go, it is a $150 part. The next thing is they try to make their own dowel pins, instead of getting a complete gasket/dowel pin set from a place like Golden Eagle. Their kit has the head gasket for the swap, a regular LS, or GSR gasket has to be modified to block certain oil orifices for the head not to leak. This leads to the other major thing, they fail to take the head and block to a machine shop to get surfaced so they seat properly. And last but not least they seem to forget to replace the timing belt, and oil pump. All these thing will lead to failure of the engine, causing people to call them unreliable. I am proof that if it's built right it will last. I have a 99 civic coupe with a JG Engine Dynamics bottom end (B18B1) and a fully built Skunk2 head from my old B16, making a LS/VTEC engine. It is running a Peakboost GT35R turbo kit, snow perfomance methanol, AEM EMS, LSD, and other stuff (too much to write) and at 40 psi it makes a little over 700 fwhp. It runs 15 psi for daily driving and makes 419 fwhp and has been this way for over 2 years. I have had no problems, except for traction, and it has never let me down. As for the power it makes, a stock GSR puts down right at 145-150 fwhp on a dyno, and a basic LS/VTEC will make around 175 on the same dyno.

GOOD LORD people are idiots. A stock GSR has 170 CRANK HP, at the wheels in stock form they put out consistent numbers of about 147-152. a LS/VTEC is reliable, but a little care has to be done to ensure it. You must get a GSR water pump because the LS has 19 teeth and the GSR has 21 allowing for more cooling with the higher revs, a conversion kit is a must, not home made oil lines from home depot, a proper conversion head gasket which blocks the proper ports and a nice set of ARP headstuds. The LS/VTEC when made with a LS bottom end and a B16 head will make about 175 whp with the stock header and air intake. Usually about 180 is the norm with a exhaust, header, and intake. This can be done PROPERLY for about $3,000. Compare that to a K20 which will make the SAME whp 170-180 the swap will run about $10,000-$12,000, and a B18C swap will be about $4,000.

hp wise and ls/vtec probably would have around 160hp. For a "stock" ls/vtec, that is.



a "stock" ls/vtec, ie stock vtec b-series head on an ls block would not make any more power than a GSR. Reason being, it does have a lower compression ratio (stock ls compression ratio is 9.0:1 and with a vtec head it bumps it up to around 9.6:1 vs the GSR's 10:1)



Also, the ls block does not have oil squirters for the pistons which is a good thing on a motor with cast pistons.



ls blocks do not have a block girdle and they use pop rivet sized connecting rod bolts which are not good f or a high revving motor.



Also if you are using a ls transmission you will be slower because it has the longest gears out of all the b-series transmissions.

Don't listen to Jason about the 140 HP. A stock non vtec 1800 Ls has 142 HP so I doubt it would lose 2 HP. The Ls has lower compression pistons so unless it is built up the same, it won't have the 174 HP or a GSR.

ls/vtec conversions are ghetto. too many corners have to be cut to make it work. metal has to be shaved, oil ports don't line up like they should, etc. all motor, an ls/vtec motor will cost less than a b18c gsr, but reliability will be a big issue. just get a b18c, build it right, and be done with it.



a stock b18c u.s. spec is 178 bhp, 170 advertised.

a b18a block, b16a2 head, you MIGHT make 150-160 bhp with the right tuning, no more because the bottom end isn't balanced for over 7000 rpm, below where vtec makes most of it's power.

with all money well spent you can get yourself a H22 already. you spend as much as getting a gsr or building a ls vtec.whats the difference, with the h22 you get more power more torque for the same amount of money.

ls/vtech should have closer to 200 hp if built right. So it should be quicker than a GSR.
