Draw Through Turbo Carby Settings

Featured Replies

Hi I'm from south australia and am new to all this so sorry if I'm stuffin up your boards lol :) . i have a 2 door 1975 ke30 corolla that i have just completed a draw through turbo set up on. i have locked the distributor and set it at around 17- 18 degrees. i am using a turbo from a 12a rotary running around 5-6 psi (soon to be 8- 10 psi) and a 32/36 webber running 98 octane fuel. i have found the webber to be really rich and i have down jetted it by putting a 175 in the primarys and a 145 in the secondrys but is still really rich. i was wondering who else on here has done a draw through set up on a 4k-c and what carby and settings they used or would advise

 

When i figure all this out soon ill put up some photos of my car and engine

I'd use a Stromberg off an old Saab. Good carby.

oh ok sweet cheers!!!

um nah i bought it of some old guy just out of adelaide can't remember his name but i have done it up a bit since then i will get some photos up of it asap!!

The carby I used would be ideal for your setup, it will tuck nicely behind the headlight with a small pod filter, then you can be fully sick and remove a headlight for drags hehe

Hey mate did you change the seals in the turbo to run draw thru or was it already setup?

oh yeah 4 sure lol :) i havent touched the seals as its a turbo from a 12 a rotary she already has carbon seals in it!!

Good stuff, didnt want it shitin on ya.

are roller bearing turbos ok to run fuel thru or do they have to modified aswell?

You can run the booster vac line to the original spot as it has a check valve in it, and your manifold will supply vaccum at idle.

That wont do him much good when he wants to stop

 

Its not an issue as long as the check valve isn't farked. I can still step my my brakes when I'm on boost. Then again you've got a crazy big volume after the throttle body :)

Have you actually tried driving this yet?? guess so.

 

How laggy is it? cause thats a bloody big turbo for a 4k. mines off a 2 litre wrx, but you should really consider the 12a as a 2.4lt when your interested in the turbo so i can see it be VERY laggy!!
