Ls Vtec or GSR swap?
 

What do you guys think? trying to decide which to do based on which one is more reliable and which one would be cheaper?

Re: Ls Vtec or GSR swap?
 

lsvtec=reliable if you spend and do it right which makes it expensive, but fast
gsr reliable, expensive, and slower than lsvtec

Re: Ls Vtec or GSR swap?
 

I have a build thread on here where i'm building a b20vtec for my ssbp gsr. its getting expensive

Re: Ls Vtec or GSR swap?
 

Yea i was shopping around and i think it would cost me around $3k just for parts alone on a ls vtec build....sounds about right? I was considering boost but kinda just prefer reliability of all motor, plus front mount intercooler attracts too many theives

Re: Ls Vtec or GSR swap?
 

i've had 3 95-99 gsrs (stock) now. and 2 ls vtecs (stock), reliable+fast=GSR...somewhat reliable(if the time and money is spent to do it correctly) and fast

Re: Ls Vtec or GSR swap?
 

Go straight gsr with the head and block with type r internals and bolt ons. You will be happy. Lsvtec or b20vtec won't be as reliable as a b18c. Think OEM in what your building.

p72 head & block(refreshed/resurfaced with new OEM seals and OEM gaskets)
ctr cams
supertech valve springs and retainers(type r is cheaper)
type r t/b
skunk2 i/m
81.5mm type r pistons(honed & bored)
OEM bearings

Pm me if you have any questions.

Re: Ls Vtec or GSR swap?
 

The cheaper route is prob piecing a turbo kit togather on your stock motor. I know people that went this route and they spend under $1,500.

I did the LS/V but was not happy with the power so I'm in the process of rebuilding it this time with higher compression for ITBs.

Re: Ls Vtec or GSR swap?
 

u should just go LS/T
buy another LS motor, build it, boost it and drop it in.

Re: Ls Vtec or GSR swap?
 

i duno why ppl say ls.vtec / b20's arent reliable. theyr just as reliable if you were to build a b18c, b16a it depends on the builder. And if ppl are gonna talk about the rod/stroke ratio, the rod stroke between b18c and lsvtecs are 1:58 and 1:54 if ur worried about that then go drive a b16a and leave all the power for us.
To op i suggest LS/VTEC build it properly and yull be laughin all over the gsr's
endrant

Re: Ls Vtec or GSR swap?
 

depends on your goals. gsr is gonna be a simpler project. and with cams and valve train and bolt ons it will run quite nice

Re: Ls Vtec or GSR swap?
 

Exactly, it all depends on your goals and what you want out of it. If you want a nice stock motor i would find a jdm gsr. I had a ls and swapped it out for a gsr hugee difference. I also did i/h/e, racing clutch, skunk2 im and mounts.

Re: Ls Vtec or GSR swap?
 

just built a b20vtec myself with 85mm rs machines pistons, my first build, pretty easy, not too expensive and stomps gsr's
all ****in day. Oooh and i used gsr rotating assy for the stronger stock rod bolts and slightly better r/s ratio.

Re: Ls Vtec or GSR swap?
 

gsr

Re: Ls Vtec or GSR swap?
 

anything is reliable if you spend money on building it right and getting the right parts...ls/vtec or gsr...

Re: Ls Vtec or GSR swap?
 

The question here is can you actually build a reliable and fast ls/vtec considering that 90 percent of them are built wrong? If you do great, go for it. If not, it's up to you to take the risk. If this is the case for you, I'll say just stick to a gsr swap or a swap of of some kind. Don't look down on boost. If your motor is fairly healthy and you don't always bang on your car, a boosted car will last you at least 5 years even on stock conditions. Personally as for me, I have always found turbo the easier way to go. The key is just tuning when it comes to any n/a or turbo build. For 3k, I could get a lot out of a turbo if you know what you're doing. My bro and I slap on a t3/t4 turbo for his stock single cam. Did everything under 5 hours with a total budget of 1700. With the first tune, set at 4psi (due to bad spark plugs, distributor, and spark plug wires) he cranked out 140whp and 140 wheel foot lb. of torque (with mostly stock application considering we didn't even have a 3" piping etc etc). Not bad if I could say so myself.

Re: Ls Vtec or GSR swap?
 

what are you on about 90% of them are built wrong?. Its when tight ass people dont change nothing to the bottom end thats when theyr built wrong. GSR is slow as shit swapping out from your LS i assure you wont be happy for the money spent.
Buttt your saying what is more reliable to be honest your going to be getting a used GSR right? vtec motors are surely enough have been giving a hard time who knows if it blows smoke, how manys kms its done etc, Lots of things to consider. If you want reliablility i suggest you rebuild your own motor so you know everything and every part is in working condition.
and ASG00 why would you bore out the already thin b20 sleeves to 85mm, then put in a GSR crank and rods?. does boring out defeat the purpose of reliablity.

Re: Ls Vtec or GSR swap?
 

Why bother asking me the same question when you have already answered it? I already know why 90 percent of them are built wrong and if you have been keeping track of the past and present post on builds dealing with ls/vtec left alone b20vtec, you'll understand why. Besides, building the bottom block is only one of the concerns and there's FAQ outlining these concerns as well as the proper way to build one. To down play gsr motors like that is quite ignorant. These motors hold extreme potential and a majority of them are key players when it comes to 500-700hp builds. Your definition of "reliability" lacks logic. So you're telling me that people build ls/vtec or b20vtec for reliability? Built motors that are meant to be beaten day in and day out is going to outlast a stock gsr motor? I'll be surprise if your builds even make it to 150k. For any individual who knows their "sources," they should be able to obtain a non-defective gsr motor easily unless they blindly buy things from people especially on cragslist. But the question here is, "
What do you guys think (ls/vtec or gsr)? trying to decide which to do based on which one is more reliable and which one would be cheaper?" If you want longevity with decent power, a gsr swap is well more than qualify, and I can assure you that buying and swapping a gsr motor is no where near 3k when compare to a ls/vtec or b20vtec build.

Re: Ls Vtec or GSR swap?
 

wow lots of great information here.

Re: Ls Vtec or GSR swap?
 

agree

i would type my own thoughts but this thread seems doomed to massive FAIL.

kids seem to chase fashion with hondas. no idea why, they just do. power is made in the top end, the bottom end just has to hold up. comparing an LSV and GSR, it's laughable. the GSR is actually designed for 8200 and is what, a few cc's smaller? what's that, maybe 1-2hp if the LSV has the exact same other parts?

i wonder if this will turn out to be another 5k LSV build that's slower than a stock ITR?

yes i have seen that, more than i would like to.

Re: Ls Vtec or GSR swap?
 

I answered why the bottomend goes im questionin ur 90% show me ur evidence how 90% of these builds built wrong.
Im downplaying GSR motors cause the stock performance is shithouse and he will really regretting not rebuilding his own engine if he comes across a lemon, Whether it be from a craigslist or your friends house most ppl dont give out a warranty on these used engines. But engine builders do.
500-700hp builds??>lmaoo these motors are certainly not using a stock gsr engines and if they do it will only be the only time you will see that figure on the dyno before they see pieces of cylinderwalls flying out the block.
Your definition of "reliability" lacks logic. So you're telling me that people build ls/vtec or b20vtec for reliability? Built motors that are meant to be beaten day in and day out is going to outlast a stock gsr motor?
My definition lol or your definition? so your saying just because you have a built motor its going be beaten day in and day out. A built motor will piss all over any used GSR in terms of reliability - Your arguement is invalid.
I'll be surprise if your builds even make it to 150k.

I will continue to build my 2.0L frankenstiens with greater hp/torque than a B18C will ever output..

Re: Ls Vtec or GSR swap?
 

5k LSV build thats slower than a stock ITR? Show me please?

Re: Ls Vtec or GSR swap?
 

For dd, I would just go GSR. Just dont be cheap on the LS/V build.

Re: Ls Vtec or GSR swap?
 

drove my gsr 8hrs to the beach and beat on it going there and back thats reliability . If i had a ls/vtec i dont think i would of been able to do that. Its all in the build and how its build.

Re: Ls Vtec or GSR swap?
 

Calling the B18C1 '$h1+house' is idiotic. It is a very strong engine with unimpeachable performance from the factory. It remains an object lesson in how to design and manufacture an economical, driveable, high-output, low displacement engine, despite the fact that it is now over 15 years old.

How can you complain about a silky smooth inline four that revs eagerly to 8200 rpm, develops nearly 100 hp per liter, and has a flat torque curve from 3500 to 8000 rpm?
