hi,

I've got a little question (already searched alot)

I will swap to a 350 with some 350 heads, maybe out of a 92 trans am (larger valves, ported, machined for more lift)

my question is now, what amount of power will the tbi support (ultimate tbi, 350 injectors) + walbro fuel pump

will it support something like a lt4 or zz4 cam. I doubt it....

what will be the largest cam I could use with that combo and makes sense?

I now have a cam out of a lt1 caprice, but even with 1.6 rockers, that cam would be pretty mild for an 350!

I don't wanna make a big swap just to realize later, that there is much more potential in it.

don't care about the chip tuning, maybe I will have a great solution for that (guy with dyno..)

just in case everything is correct with chip, head etc., what can I do with my tbi??
greetings

With good heads and ZZ4 cam it should be good for some power. Also grab a 454 tbi and 80 pph injectors. The holley unit with the '85 pph' injectors will also work but must be run at around 30 psi as they use smaller 4 banger injectors.

With tuning it should be good for 13's. As for chip tuning, Id care. The computer will fight you every step of the way if you cant tune it.

 

mhhh, ok.

but how far can I go with my (nearly) stock tbi and the 350 injectors?
it doesn't have to be the zz4 cam...just something bigger than the lt1.

I really care about the chip tuning, but I wanted to say that nobody needs to say that I have to do it, cause I know.

eventually a guy from the us will come to germany with his equipement. a dyno will be hired, and the chip work can begin!

You pay for the plane ticket, and feed me . . . I'm game.

 

looool, if I had that money I won't care about injector size and whatever

that will be an action from the f-body europe members, and hopefully the engine is done when all that starts.

Actualy,

I am planning on going to europe in the next couple of years. I went over once about 5 years ago, and am ready to go again. Germany is on my list. I am dying to run a couple of laps on the n-ring.

 

are you serious??

when do you want to come? where will you live?
I'm living between karlsruhe and stuttgart, so you have an idea.

I will go to the n-ring next weekend look at my cardomain in the sig, there are a few nice pics of that track :hail:

I'm living between karlsruhe and stuttgart, so where would you live if you would come over there?:hail:

 

I won't be moving there. Just visiting.

 

ahhh, ok!

when you know, where, when, whatever...let me know it.

do you have any suggestions about my little cam problem.

with the cam I have and 1.6 rockers it would only have that specs:
int exh
446 459

not that wild for a 350!
but a zz4 would be too much for the 350 injectors I think, so what now

how much cam can these injectors handle, especially with some good flowing gm heads?

S!MON

 

That really depends. It is going to come down to the HP numbers, and RPMs you will use it at. I'm doing pretty good with the 305 injectors, the 350's would be a little more. The ZZ4 cam i would not call radical either, I suspect you would probably be OK with it, and the 350 injectors.

What we should do, is a parts trade. I'll dig up some BB injectors for you, and a cam, and ship them to you. You can find me parts for my Audi.

 

mhh, if you think that cam with that injectors would be fine, then I'm happy. how hard will it be for a good tuner to get that combo running?

hehe, what kind of parts do you need for your audi. I think ebay.de will rule on this
so maybe I don't need the cam & injectors, but maybe we could do a little chip work when you visit good ol germany, lol

I'm looking for S2 or RS2 front/rear bumpers. And an S2 or RS2 exaust manifold for the 20v 5cyl.

 

front:

s2
rs2
even more


back:
klick

exhaust:
they all write 16v?!
turbo?
more

haha, happy ordering

there's also a lot of tuning stuff like cams, turboss and whatever...:lala:

Simon,

Since i've never tried Ebay.de, if I contact those people, will most of them be willing to ship to the states?

Since no S2's or RS2's came to North America, finding that stuff here can get VERY expensive (a place imports them in the states, and sells the front RS2 bumper for $1500).

We probably should not do this in this thread, do you have PM's turned on, or AIM, MSN, Yahoo, etc??

 

oh, that's the same problem I have with my chevy over here

I will will pm you my icq-no. and my e-mail adress, so we will find a way!

S!MON

 

If you ever have problems getting a part, let me know!

 

In the end the cam is up to you. The 350 injectors wont go far at all. The bigger the better. The stock tbi also isnt that great. I was pulling almost 3 inHg of vacuum with my 350 and low rise dual plane intake.

 

so, where do you think will be the limits with the 350 injectors?
which numbers could I see with that cam in a tbi unit with what injectors? especially with the 350s?

because I won't need a bigger cam, if the injectors couldn't feed the needs of my engine.

how much will be a set of injectors?
greetings
