question about carb for turbo setup
I was wondering if using a 45mm Weber Dco carb would work okay with a turbo setup.. yes i am refering to blowthru.. and it will more than likely be a stock turbo.
|
for stock port it would be okay, but if you go street port, and alot more power youll probably want to upgrade. but yea a 45 would be okay
|
well i wasnt going to do any porting until i blow the engine... then i may do a half bridge.. so should i just get the 45 for now or shoudl i get a 48?
|
go ahead and get the 48. just use smaller chokes till the motor is ported.

why not side draft... wouldnt it make more sense.. especially with intercooler hose routing?

do some research on tuning side drafts and you'll understand. if you can't tune the carb then forget about boosting it ;)
just some warning.. it isn't easy. |
i had a turbo on my 68 impala with a 4 barrel carb.. and i didnt do much to tune it.. so i think i can handle this.. especially since i am a mechanic.. but thanks for the warning.
|
would a downdraft be better then sidedraft?

you can read my SIG ...

i would just about go to say its almost impossible to have any kind of reliability with that much power thru a 12a. if the dyno wasnt setup properly do you know they can give you an incorrect figure, also some people pursuade ,as you would want to say, the numbers on dynos. |
700rwhp is completely possible from a 12a. Rob at rotaryshack makes 730rwhp out of his. made 550rwhp using the stock nikki carb. but to go way past that you either need a nice blow thru holley like the mustang guys use or Stand alone fuel injection with ITB's.
|
funny thing.. a thread about blow-thru carbs and we are to read his sig...
which makes no mention of any type of fuel induction system whatsoever, unless its that mystical "port bolish" that seems to be popular with the young-uns lately. |
yeah i am not looking for anything more than about 250... i think that is all i would ever want from such a small car..
|
yea 250 is rediculously fun in these cars!

my favorite is still the PORT BOLISH :p:
and if it's just a greddy T88 then he's gotta have that boost cranked to get 700rwhp. it's not an 88mm turbo like some think. hell the people with gt42's and 47's are running crazy boost to reach this number. i'm not buyin in to it yet. |
yeah what a tard.. so fbII everyone on the ohio board thinks i should just get a T2 engine and drop it in.. but i think i may have more fun with the 12a being turboed.. i respect your opinion and would like to know what you think..
|
it really all depends on how much you want to spend and the patience you have. i love having my 12a turbo setup, but i won't lie... sometimes i wouldn't mind having a TII motor in there purely for the fact that i could just slap on a 62-1 and make 350rwhp no problem. with the 12a i am forced to tear it open and port it. BUT, when the 12a is ported with that same turbo i can hit 400rwhp at the same boost level. sooooo, asdflkaslfkjaslk;jflkasjfk it's a toughy :D
if you have the funds go for the TII swap. |
well i have the funds.. but i really wanted to see what i could do with the 12a... not to mention i hate computers.. so i wanted it to be carbed... maybe i could carb a T2.. i dont know.. i will see..
|
you can carb a t2 that is what a lot of people do. Hey FBII didn't Robert make 680 rwhp on a weber 12a blowthrough. I'm pretty sure he did then he went FI and went over the 700 mark.
|
carbing a turbo 2 motor is easy!!! if you have any questions please e-mail me :) robert@rotaryshack.com
oh and for the record it was 540 rwhp on a 12a turbo with a nikki and 730rwhp after the efi conversion and more boost :) |
thanks robert.. email sent. I am still confused about what i will do but i have all winter to debate it.
