wondering what size belt im supposed to use for use with the n1 crank pulley. would 95 prelude injectors flow more than injectors on 95 ls? i think the integra flows 240cc, correct me if im wrong. i thought the prelude injectors were like 270 or 280, if i can use them would it be worthy upgrade for an all motor engine. if i upgrade injectors should i upgrade the fuel pump? just looking for someone to kind of point me in the right direction, heres a list of my set up so far:
95 ls motor
b16 pistons ls rods arp hardware
crower 403 cams, crower valve springs and retainers
skunk 2 im, hondata im gasket
aem cam gears
b&m fuel pressure regulator, and a billet fuel rail
n1 crank pulley
msd plug wires, msd blaster ss coil
hondata s200
i plan on using 100 octane, what kind of power do you think ill make?
i know its a lot of questions thanks for your time

 

ur not gonna have to use 100 octane. ull be fine using 93 octane. as for power i dont know. but y dont u just do an ls/vtec vtec heads do have there advantages. besides the ls heads arent nething to brag about. what size is the cam ur running cause if its too big of a cam ur gonna have a problem idling.

 

as for the timing belt. you use a normal sized timing belt. the ctr n1 pulley is the same width as stock so you would run a stock sized timing belt.

 

The ALTERNATOR belt for the N1 pulley is shorter, I will see if I can find the NAPA number. The Prelude injectors are larger, but peak and hold so you would need to wire a resistor box in the harness. You will be fine with the stock 240's.

 

1992-96 Prelude VTEC Peak and hold 345cc
1997-up Prelude VTEC Saturated 280cc

if you have a ls fuel pump (79.92 lph) ditch that pos and upgrade to a gsr/itr (131.04 lph) you might have to get a vtec fpr if you using the 240s, the gsr has the highest pressure.

 

i was sure if i could use injectors from a 97 or later prelude because it was obd2 and my car is obd1

 

You could use either, but the earlier (like donf said, are gonna reguire a resistor box). The obd2 injectors are saturated, like your obd1 injectors. So you wouldn't have to add a resistor box but you will have to change your obd1 style injector clips(grey,metal clip) for the obd2 style(black,squeeze type clip)...very easy, I change the clips on all my cars for ease of taking them on and off.

 

like don said you'll be fine with the 240's. they have been proven to close to 200whp,and i dont think you'll be near that.if your gonna upgrade the valve train and tune i would go with the 404's and they are very streetable. as long as the stock fuel pump is good it will also be fine. have you ever thought about just getting a vtec head instead since you already have the bottom end good.

 

well the thing is i bought the engine like this for a deal and a half, so im just trying to get the most out of what i already have because it wont cost me as much as going ls-v right now. so the motor is alreay built im about to drop it in, i was just trying to get parts in order to make it a little better, plus be able to use them later when i decide to go another route, wether it be ls-v or turbo, which i know id have to change pistons for turbo but the point is someone already did all the spending.

 

not trying to take your post but should i run the prelude injectors on my b20 because some people say if i run the b18 it will run lean.... or i can just run the b20 injectors can i ?

that's only if he has a stock VTEC fuel pump. even 310 cc DOES NOT support the power the 404 makes w/ a NON VTEC fuel pump. im running 404's and rc 310 at 90%+ duty cycle at higher rpm and she still wants more fuel. (im keeping her under 6k till i upgrade my fuel system)

i would only run 240 cc if your making less than 190 crank hp. look at RC's injector size calculator

my good friend makes 193 with a itr but they were maxed out. i doubt any mild 1.8 non vtec is gonna make over that.

about the N1 pulley belt.. I have one sitting in my car, but I found a few part numbers and sizes by searching.. https://honda-tech.com/zerothread?id=1520094

Its fun revving with that pulley and a flywheel

 

I have a 95 b18b1 motor in my 92 cx.

It has

Head
Crower Valve Springs and retainers
Stock Valves(3 angle valve job)
Port matched head.
Hondata intakemanifold gasket.
310cc prelude injectors
Skunk2 OLD Style Intake manifold.
Edelbrock 65mm throttle body.
ABS plastic Whale dick replica
Crower 404 cams
NGK 7's plugs.
new coil, cap, wires etc etc.

Block.

Fully balanced.
Factory main bearings.
Standard rod bearings.
Eagle H-Beam rods.
Arias 12:1 LS pistons.
Fidanza flyhweel.
Had a unorthadox crank pully(wanted ac so put back the stock one).

RMF replica header
2.25inch exhaust.

184whp and 135 torque.
I have no dyno graphs to post, but it's very fun in a car that weighs about 2200 pounds with me in it(weighed 2380 w/ full interior and me in it, now its gutted).

I daily drive the car. On average in the city, I get lower 20s, like 23-24mpg. Interstate, it's crucially good.

Its mated to a ITR trans w/ Kaaz lsd.
Solid mounts.
Comptetion Stage 4 clutch sprung 6puck(I had it from my turbo setup).

Motor wasn't built for this car. Built for a 'ef' four door and we were going to spray it, threw it together for another car after that car got stolen. Sold the car that got stolen after we recovered it and put it in mine.

All in all. Unless you just have a head and some cheap cams (like I did) and you wanted to spray a motor. Do it. I wouldn't build this motor again.

This motor will be going in a 89 hatch taht has more rust than paint.

a stock fuel pump thats in good working order is more than capable to supply fuel for a mild all motor project

LS FUEL PUMP 79.92 LPH!!!!!!!!!! = NOT ENOUGH FUEL.

fyi
40 ish psi at the filter.

 

thanx for findin that thread
