just a quick one

what would you recommend

keeping with std injection so no carbs or tb's lol as its just a run around

but as for cams etc

which would be better :lol:

ebay chips ;) lol

id personally stick to the NVO series of cams from Kent (or the similar series from piper) as they are designed for injection use.

Or try a catcam profile. but to be fair if your not fussed about performance etc as its a daily drive then its going to be very mild stuff that you fit and probably not really worth it in the long run mate. keep a beady on egay..

Tbh, i dont think you would see that much of an increase by fitting a performance cam if staying with standard injection and management.
I'd just leave it standard, maybe an aftermarket exhaust, but thats all i would do.

Before my engine was reborn many moons ago i ran the nvo62 cam coupled with my head and the usual filter/zorst etc and to be fair it went well for what it was, a marked improvement over standard.

Was that using std injection or on 40s?
Any ideas on what power increase the cam added?

on the group a ones we have to keep the std plenum and AF meter, but we rip guts out of it and use a standalone ecu.. eg emerald/mbe/motec and then you can run a good cam.

keep the std af meter and gut it to bend the rules? otherwise why bother with it.....

its not bending.. its the norm.

same rule as the hot hatch series.. engine must be externally identical to std.

Ye, thats why i said i dont think the improvement would be much using the standard ecu, but with mappable management, its a lot better ,lol. :)

im planning on dropping a 1.6 8v mpi into my crosa 1.4, ive been told by my mechanic that i can put in 2.0 injectors, fuel pump, throttle body and ecu, along with fse boost valve and k&n induction cone, this true? how many horses would i get form this?

cheerz!

That was on the engine when it was still injection (i've had the engine 9/10yrs in total lol). As regards what power the cam added the engine was done in one hit back then rather than bits and pieces. There maybe better ones or options on the market now but for me that was good back then

it will give you lovely bore wash and crap mpg with little or no increase in power.... so yeah go for it if you want to screw your engine :D

The standard 1.6 injectors and throttle body can fuel for upto 150bhp IIRC.
And it will only use the fuel it needs, excess fuel from the pump will just get sent back to the tank.

And bigger injectors, as Stu said, will rid the bores of oil, which you dont really want,lol.

Dan-I was thinking of a 1600 engine, running standard everything apart from the cam, but i was told that the standard AFM doesn't cope too well with cams above about 290ish duration. Something about the air pulsing instead of flowing. I dont know what the Kent nvo62 spec is tho, as it doesn't seem to give much detail on the Kent website.
I think thats what i was told anyway,lol.

Best mod on my 8v is the big valve/flowed head. I had a Piper 270 IIRC, made a reasonable difference & definately made the exhaust note really deep.

2.0 injectors didnt work for me, it wouldnt even fire (too high impedence)

I'd do an AFM mod, there are 2 you can do. PM me.

the nvo62 was a 270 also and met the requirement perfect. Alot of people bitch its not worth it with cams below 285 etc but its dependant on application and if you want something abit nippier or an all out race engine lol.

the gte lump (e16se?) has 101bhp? what can be done to it to get it to about 120 to 130 bhp?

101 when new.... probably isn't that anymore...

could do cam, head work, 4-1 manifold, full exhaust system, twin 40's
