Experienced cam users please lend me some help...

Hi,

I was reading in a post about the hks cams not requiring adjustable cam gears. I was under the impression that the only reason to have cams was in combo with the gears so that you can tune them.

But do you really need them? I have the 264/272 cams sitting here next to me, and If i dont need the gears, ill get them installed 2morrow. Also, Im still running stock injectors @~ 12 lbs on a B16g. Will i need to upgrade the injectors before install the cams?

Thanks alot,

Martin

You don't need adjustable cam gears. You may want to keep the boost down until you get larger injectors though.

with any cam, even the hks, you could gain power if you took the time to take the car to a dyno and tune them with cam gears. HKS have been proven to be made well and just dropping them in will be close enough. Also, if you want to see the full potential of your setup you should definitely get some injectors. With the b16g alone you couldve maxed out the stock injectors.

Thanks for the input. Now just gotta go get em installed. Any recommendations on inj. size? I was thinking like 660's.

what size fuel pump do you have? if you have a 190 then get 660s if you have a 255 get 550s, then tune it cause upgraded fuel uncontrolled is not good.

I have a safc. I also have a 255. But I cant get 660'S? Isnt that waht the safc is for?

 

[Sephroth57]

660s are fine, i dont think he knew that you had a SAFC. do you also have a logger? an AFC alone cant tune efficiently, it only changes your A/F ratio, you have no way of knowing how much more/less fuel you need without a logger

 

[StarCraftLover]

Nah, how much is a logger?

how would the greddy e-manage work in his situation?

255 and 660s would be fine...Im just saying for a 16g turbo 550s and 255 or 660s and 190 will max the turbo out and still have plenty of fuel left over just my $.02...

Please explain the above
What does the different pumps have to do with the different injectors.

If he's running a 16g he will not tax a 190 pump.
A 190 is all he needs.
As far as injectors, I'd go with the 660's. This will give you some room to play with.

edit......oops I just saw that he already has a 255. just get the 660's and an AFPR

I obviously wasn't clear enough for you.

Please explain why you say 550's with a 255 or 660's with a 190.
What does the pump have to do with anything?
The 190 will work with either set of injectors and his set up

because 550s and 190 arent enough to max a 16g to its potential...

Andrew

so you're saying that 550's and a 255 will max it out

Maybe I'm just misunderstanding what you said.
We maybe saying the same thing....

I understand and agree that 550's can be maxed out by a 16g. Hence why we both say go with 660s.
but a 190 is more than enough pump for a 16g

I was just confused why you changed pumps with the different injectors.
190 with 550s=good potential but could max out the injectors only.
190 with 660s=better potential/room to play. Should not max out injectors or pump.
255 with 550s=same as 190 with 550s
255 with 660s=same as 190 with 660s

With either pump and set of injectors you could add a AFPR and raise/lower the pressure.
With the 255 you're almost garanteed to need one.

Like I said...I was just confused why you changed pumps with the different injectors.

 

[DSMeclipse4G63]

yeah we are both on the same track as far as I know...

You have a 255 and that is a good choice. I would get 660's for the extra room to play and get the absolute max out of the turbo. I would also get a FPR becaseu that 255 will over run it. Some say that it is fone just by itself but why make sure it runs perfect. This goes along with the cam gear question. Why leave something to chance when you can know for sure there is no problem. So many people want to go fast but dont want to spend money to do things right.

Get the cam gears and FPR and tune on the dyno and I bet you will have a car that runs hard.
