my boy was telling me to sell my gs-r motor and get a ls-turbo .. i said why and he said its a good setup its good and fast for street racing... what do u guys think? and the motor is in a integra so?

 

well ur friend needs to look at it on both sides....if u turbo both engines u will get alot of power....more power on the GSR for sure...but on the LS since theres lower compression you are able to raise ur boost...a lil more....either one is good....but if u were gonna go all out i'd keep the gsr motor cause ur gonna swap in lower compression pistons anyhow....

keep ur motor.....ur motor is expensive... you'll have a TURBO VTEC

 

ls motors are cool

david--> who thinks ls motors arre cool

 

a GSR motor will make more power, GIVEN THAT IT IS SETUP CORRECTLY. The head simply flows more air, it's as simple as that. If there's a budget on the project then you might want to go LS because for the price of a GSR motor you can build up an LS motor that will make more power, that's what I did before.

 

Personally I am running a completely stock LS motor (never had the valve cover off) with 12psi on stock injectors, a high flow fuel pump, Drag 2 kit, full emissions, and an Apexi Dunk. The car is putting out 253 whp on a 105 degree day.
Many VTEC motors I have seen can't do that with the same setup. VTEC doesn't seem to help forced induction motors, too much overlap, the boost blows thru. Better off investing in a good head rebuild with valves etc, to possible raise the top of the rev limit to 8000 rpm.
Just my .02
From someone already there.

 

Without a doubt turbo the GSR. When my car was on the dyno when we were tuning Vtec wasn't working and the car was making 300 horse...after vtec worked it shot to 390 with no other changes. soon afterwards i was at 405...trust me go with the GSR.

 

id have to disagree... there is definately a lot more power once vtec hits... u feel it more than a non-turbo car imo

 

I dont know where U got your facts but a GSR will ,make that and more once its properly tuned how about 379 WHP. A custom kit on a GSR will yield upwards of 450 WHP

 

12 psi on stock injectors, that has to be leaning out.

 

gsr

 

On a stock GSR motor you should put down 240-270 easy.. With a built one even more.. I hope you do it right and build your bottom end.

Hey Tony I bought that Type R cluster from you remember me, so you goin boost now??

 

hey bro whats up... hows the car.... u know anyone who wants to buy a gs-r motor

 

full swap or just the motor??

 

HOLY ***** you run that much boost on the stock guts? Is that car daily driven? if so at what psi? I run 5 on stock everything and am toying with the idea of 6-7. still need to get exhuast first though.

 

at 12 psi, a gsr would KILL that number (240). That seems really low for that psi. most bolt on kits that I've seen on the net pull 260ish with stock boost (half of what you're boosting).

 

I am confused how do your stock injectors support 253w and approx. 307BHP????
I dont even need to do injector math to know you must have a different fuel setup - your pump may give you an additional 1lb/hr fuel thats it.

 

Maybe my car is running lean but i ran those number with 118 octane fuel.
Normally i run 7psi on 93 octane, 10 psi with pour in octane boost.
As far as the fuel system, stock injectors, upgraded fuel pump and whatever fmu that comes with the Drag 2. As far as theories go, i was there and i have the dyno numbers to support that statement, it was done in Houston @ hocus- Pocus Auto.
I have spoken to many race car builders and understand that drag cars don't usually run VTEC on blown or FI cars?

True VTEC does have too much overlap, but if im not mistaken cam gears can help with the overlap problem....the good thing about VTEC is the increase in lift...which allows the VE to be better, which basically means it flows better...
Plus that 8100rpm redline helps to make power..once you get new pistons in there, the lower compression advantage the LS motor has is gone..

Octane Boosters really work?

 

You have to buy the 104+ octane booster for racing use only (available at your friendly Wal-Mart). The bottle will say good for 4-5 pt octane increase with a 21 gallon tank. What i do is mix 1 bottle with a 1/4- 1/2 tank. Should be equivalent to about 104- 108 octane. I have been doing it for about 10 years.
Previous cars include a Buick Grand National, Old School Mustang 5.0 with NOS, and twin turbo RX7. The octane boost works when you can't get your hands on true race gas. Only costs $7.00 a bottle

How about do it on a Type R ??? I wanna turbocharge my car for sure but i dont should i get the 2.0 block instead..the 1.8 cause my cousin just crash the brand new CRV and he will give the block to me ..IDEA Pls..
