i have got a 91 integra it has gsr pistons in a stock bore ls block with an ls head, stage 2 clutch, coilovers, an exhaust from the previous owner which is ridiculously loud and annoying, my mfuture plans 2.0 ls block 10.1 compression pistons, 5 angle valve job with stainless steel stock size valves stock cams, and turbo kit i am aiming for 350 horse, i would like to know what size injectors i should run for this horsepower goal? and also i would like to buy 1-4 either gsr or type r gears i want to keep 5the ls 5th so i can have hwy gas mileage. any suggestions on where i can get these gears?

 

If you are turboing you should think about GSR gears so you are not shifting every second, But i would check all the craigslists around you as far as your willing to drive.

 

thanks for the info you wouldnt happen to know what size injectore i should use for 350 horse?

 

If I were doing your build I would ditch the higher compression pistons for something in the 9.0 range.

As for injectors. You'll do just fine with 550-650cc range.

thanks for the info now as for a clutch if i ran the s300 hondata i could get away with a stage 2 for low boost but still be reliable with high boost on the drag strip like once a month right?

 

Divide required Horsepower by number of injectors used...

(350HP / 4 INJ.) = 50 HP PER. INJ.

(50HP X .60 B.S.F.C.) = 25 Lbs/Hr

(25 Lbs/Hr / .80% Duty) = 31.25 Lbs/Hr Static flow rate.

31.25 Lbs/Hr X 10.50 = 328 cc/Min. Static flow rate required.

This will tell you about what size injectors to run. Go with the low compression pistons. The clutch is better base off your torque.

 

i jyust found out that my integr ahs a gsr tranny in it already i was r0olling 80 mph at 4500rpm, i talked to some people about it because i thought it was strange and they told me that that years the gsr and ls trannys were intermixed so i guess i got lucky

 

u have this new procject and there are no pics

 

ahhhhh will get up picks soon i have to find a camera to use first i am saving all my money so i can put it into my car.
