Hey I'm trying to figure out what would be better for my gsr engine. I'm thinking about going turbo but if I can get good #'s out of it naturally aspirated I might just go that route. What do you guys think WHP I can get out of a naturally aspirated GSR engine?

dmotoguy

anywhere up to 320+hp dependent on $$ and knowledge. lol

esurds

What would I have to do to get those kind of #'s?

egluv92

about 20 g's if ure going NA...

Vindicator9000

^^^Yes, but 320 would be a LOT of $$ and knowledge.^^^

Last I read, I think Larry from Endyne was running around 260-ish on his DD B20V EF hatch, and he's one of the best in the business. And that was with a non-OEM custom head, Dart block, custom manifold, custom cam, custom pistons, rods, and a bunch of other stuff. Granted, it was a B20 vtec, and I think those might have a bit more potential. I'd estimate street value of that engine to be around 10K (largely due to who built it), maybe 6-7K if you built it yourself.

OP, what's your budget and target HP? What are you intending to use the car for? All things considered, turbo HP is almost always cheaper than NA HP on a Honda, but NA tends to be more reliable.

pretty much buy a spray kit make sure is a wet shot more safe an that will give you couple up in no time

larry is also known for being wayyyy over-**** with ****.

but for someone to drop off a gsr motor at his shop and expect the op's numbers... i'd say it'd cost 20000 bucks.

OP should just stick a stick in his eye. wtf is a 'GOOD NUMBER' anyways?? ****ing tool

wait a minute.. this is not to the wheels right

My_FrankenStein[EG]

+320 to the wheels now thats pushing it N/A on a B-Series
I can see +260 on a Full Build and VP gas
but if you want a everyday driver N/A before juice you can get 210-230whp

MonkeyMagic

either way, it'll never happen to the OP

let this thread die

stock or built...
but i have seen 250+ from a built gsr on the dyno

rick_rabies

whats "OP"?

MonkeyMagic

original post or original poster... the guy at the top of the first page who usually asks the question or starts the fight

I'd like to stick with stock internals ex. cams, rods, pistons, crank. How much hp could I get out of a gsr engine with skunk 2 intake manifold, large throttle body (68mm), msd ignition, header back exhaust, and obviously cold air intake. Any other recemendations for add ons other than what I just listed?

jdmcivicracer89

nowhere near 300 whp. haha the msd is useless dont even bother with that. ngk wires and plugs and ur set ignition wise for ur setup...

esurds

Ok cool that will save me a good $200. So what else do you think I should do? Should I just go with the non v-tec b18 or should I go with the gsr? Im just tossed between the two. I definitely want to boost though. What is a good psi with stock internals?

VTECROAR96typeR

yeah those numbers are more like it

jdmcivicracer89

well if boostin id do a lsvtec and ur good to 300 whp with a good tune that is. u really should read up on boost. if u doin everything urself u got alot of learning to do. good luck

Vindicator9000

For real?

170 WHP. With a tune.

98civdx

well you forgot a good tune...
thoses mods you listed are pretty much useless without a good tune, i reccomend hondata, not beacuase everyone else does, but they are capable of growing, if you decide later on to build your motor or boost it.
with what you have listed msd igniton is a waste of money. stick with ngk and a set of good wires. maybe a msd w/external coil.

i think you shold look into going ls/vtec with some minor head work, pnp, and a valve job.
they can make great power and a decent amount of tourqe.

esurds

So I should get a ls block and get a v-tec head for it? Do you recemmend the ls block because of the compression ratio?

98civdx

for ls/vtec you have to have a ls block and a vtec head you dont have a coice.
you decide on the head tho, people say b16s flow best, but either b16,b18c or b18c5, or some sort of jdm head.
also people do put integra type r integrals in the ls block, for the compression.

esurds

So does the head just bolt right up with no problems or do I need to have work done to it to make it work?

miguel329

theres a ton of ls vtec info on the net... u can go to b20vtec.com and find like 500 pages on it.. plus if you already have a gsr then you can take that head and put it on a ls block.. i was going to go N/a but for the money i went turbo and never looked back.

98civdx

no you will need a ls/vtec kit, i recommed golden egal, every thing you need comes in the kit.
no head work needed
do a search on ls/vtec there are millions of pages of info on it
well maybe not millions but you get it lol
