HELP

I NEEEEEED some racing camshafts and some new injection jets......

Can anybody give me some information on how to find that!!!??

Why do you need new injectors - are you planning on turbo'ing your motor? The stock 259cc injectors will cope with pretty much anything non-forced induction I would have though.

If you do need new ones, then you can get some 370cc ones from a 200SX SR20DET, and these will connect to your existing fuel rail as well I believe.

I *think* you'll have to get the ECU remapped for the new injectors though - something like a Unichip will do the job.

HELLO Anthony....

aaaaaaaaaaaaaahhhh I just read your signature, and it appeared to me that my car is on your homepage.... :o)

Well anyway i have spoke to the Danish Nissan Guru and he told me that he could chip my car and combined with new injectors and maybe a couple of new camshafts he could get about 170-180HP (7.800rpm) out of my engine..... I'd like that.... he he

I assume that's crank hp. If you're getting 170-180 at the wheels you'll need at least 370cc injectors. The DET ones are just a plug in like Anthony said. And you will need your ECU remapped or some other way to change the pulse width.

If you're talking about 170-180 at the crank you don't need new injetors the stockers are just fine.

You're going to need some higher compression and some very hot cams to get 170+hp at the wheels.

Hey G-Force

Thanx for the input......

I will enlight him with yours and Anthonys input and then I will get back to you tomorrow with some more details!

To add 25-35 hp, you will probably need:

Header (extractor)
Remapped ECU
Cold Air Intake (filter in the fender well)
Good cams

You won't need different injectors.

He says I need

New ECU
New cams 280-285 dg cams
New injectors

It should work.....

Hey gurpal, you got mail!

anyway, ive got some fast road cams in and a unichip, but havent had the chip remapped for the cams just yet. There is a noticable difference at the bottom and mid range, but i was a little dissapointed, i was expecting more. Anyway, i might also look into new injectors, see what the tuning companies say around here. One of the problems are my filter, i think. It currently sits behind the battery and doesnt have a cold air feed. I might look into extending the pipe to relocate the filter in a cooler part of the engine bay, cos at the moment, it seems to be sucking up warm air.

I'll ask around, see what i find out about the injectors and let you know.

i just rang a company here in the UK called Norris Design, they say i will only need the injectors if im having fueling problems with the new cams, but until i get it remapped, i dont know, aaaaahhhhhh vicious cirle kinda thing going on. The stock injectors should be able to handle a bit more horse so i dont think i'll need them. They have a set of 4, second hand which will cost me £100 inc. postage

yep got the mail....thanx....
ps have you tried cold air feed like I have for my K&N,,,,,,,,

:flash: :flash:

TeamNissan · #11 08-30-2001, 06:34 AM

Your standard injectors should handle up to 170HP

But try remapping your ECU then you will get much more out of your cams.....

P11GT · #12 08-30-2001, 09:22 AM

im gonna try getting a pipe bent to go further around and below in the engine bay to mount the flter on, to get cold air, but not too low, dont wanna hydraulic the engine. I'll have a proper look when the weathers a bit nicer here.

You absolutely do not need new injectors. We have someone here in The States putting 170 hp to the wheels with the stock 259cc injectors. He has not run out of injector either. This is verified by JWT since they he has been doing cam testing for them.

Also, you will not gain 25-25 hp from cams and a ECU remap, although 20 is on the fringe of what is possible. There is no way for you to make 170 bhp (roughly 145 to the wheels) without a header (extractor). Chances are you will need a true cold air intake as well, not just a tube running cold air to the filter.

Go for the Cold Air Intake!!!

...actually the cold air effect is minimal. The added horsepower is actually from the intake being longer and funnelling the air in at a higher speed.

boogie...... where is your filter located then? i see that the pipe goes down into the hole where the resevior would normally be. The main problem is that there isnt anywhere in the UK that sells the CAI and its a pian the ship over. How much am i looking at anyway?

I should be able to get the same diameter piping to extend it, would this has the same funnelling effect? or does it need to be at different diameters ie smaller at the filter and bigger at the intake manifold, or vice verser?
