Wazzup fellas, here's the deal, i have a civic D13, 1.3 75hp, its pretty weak stock, ive done some mods on it like removing midle silencers etc, ive bolted on two keihin carbs from the 1.4 dual carb engine (D14) And i have an extra exhaust manifold, a turbo from a VW Golf GTD from the 90's, some oil lines and stuff...and have some questions...

Will my carbs work well with the turbo? I was planning on getting a R5 GT Turbo carburettor that will surelly do, but if mines hang, i would keep them eh

Im also going to buy a electric fuel pump and fuel pressure regulator to make the return fuel line ...

Im adapting the KKK exhaust flange to my extra exhaust header, get some fittings to the oil pan, to drain the oil, and a oil hose to fit in the oil pressure regulator place...

Can you see something here missing me? hehe

Cheers

i think u need a carb made for boost i could be wrong tho

Wich carbs do you think will be allright with boost? I was trying to find a Renault 5 GT Turbo one but theire all a bit expensive.

you can get your carb pressurized or just buy on that was built for boost (pressurized) all it does is add more fuel when in boost. its an airflow operated enrichment system.

you are wrong any carb can be used for boost with only slight modifications. read the book max boost it had a chapter dedicated to draw through and blow through carbs

Hmm i can search that book, must be good, how do i know if my carbs are blow through etc?

Need to find out how to pressurise my carb, never knew of that pressurisation part

Guga

Found it, maximum boost, gona read it. Any other replyes would be apreciated

the blow through draw through is named for the turbo setup not the carb. a draw through setup is where the carb is infront of the turbo where the air filter goes on a efi setup and a blow thruogh is where the turbo blows air into the carb. its a really good book i think any one who wants to know more about turbos and turbo setups should read. its a little out dated but most everything said in that book is true to this day

Ive started reading it and have already rad a bit, so what im doing is a blow through turbo build...as far as ive understood, the presurization methood makes some of the turbos pressure or vacuum suck, or blow that thing that is in the carb's fuel "tank" that stops the fuel from comming in, so it nevers stop comming when in boost, avoiding the very common fuel failures cuz of the turbos excessive air flow right?

What do you think of me using an electric fuel pump with a FPR before the carb's fuel lines so that it is allways givving fuel instead of camshaft operated fuel pump?

Cheers

Hey all, my first post here. I've built a ton of blow through setups and I'd say you're on the right track.
Use the electric pump, but use the FPR on a return line instead. You'll need to boost reference the FPR and you might need to mod the fuel pump to run higher pressure. Also, some brass floats don't like too much boost and collapse under the pressure. Find a plastic float or mod the one you have.

I've personally made 1290 HP with a blow through setup, so I know it works.
