For a b18c N/A built???

 

What are you doing with the engine?

Will you run an aftermarket fuel pump, fuel rail and fuel pressure regulator?

IMO, 450cc is always a good choice for a NA build.

Lots of stuff doesn't help, and I'm almost willing to bet you will not need an aftermarket fuel rail, but you could be swapping in an old Chevy 327 and I would be wrong.

Other then said case, I'm right.

We need all the specs for what your motor is going to be to give you the or to a set of 450s.

 

I recommend a fuel rail and fuel pressure regulator. Look at AEM. This way you can adjust the fuel pressure.

I have post my set-up a lots of time here...i will list it for the last time i hope

97 b18c ITR block
81.5mm 12:1 CR
JUN 3 cams
JUN spring+retainer
Ferrera valve
Spoon adj cam gear
Stage 3 port&polish head+intake manifold
70mm skunk2 TB
Spoon sport 2 layer head gasket
SMSP header
Hondata s100
And more stuff...

 

TB is too big and 310s will work just fine. i run 370s in my personal motor.

Its too late my 450cc are already purchase...and why is 70mm too big???

 

68mm TB sorry its my bad...

 

1.8L 62-65 IMO.

 

Do not use an AEM fuel pressure regulator. It WILL kill your motor. I have seen a few built motors go to **** because of these regulators. They have a tendancy to lean just for a split second, but on a built motor thats all it takes to cause a rod knock.

 

With Jun Cams and a SMSP header, 70mm is fine for the throttle body. You want all of the air possible for those cams

Using the AEM fpr will allow you to dial down the pressure with the 450cc injectors.

I have never heard of anybody having problems with the AEM fpr.

 

sure the 70mm will work but i think it will hurt performance vs help it. more air is ok but velocity is where its at. we dont know if his "stage 3" port is even worth a ****. for all we know hes flowing 270cfm VS a good port job of 290+. if he was somewhere near a 2L the 68-70mm TB would be a good choice.
i put down 222 or so with a stock ITR TB and IM in a 2L motor with over 13:1 CR. more displacement moves more air period.

Its your motor, but Im telling you they have issues. There are many other options out there so why not just go with one of those. You can "dial down" your fuel pressure with a diffrent type of fpr. Also if your gonna run 450's you will need a tune.

450cc ain't bad choice, but what's your setup?? aftermarket inline fuel pump, regulator, fuel rail??????
