what do u guys think bout a 12A draw through turbo kit is dwar through any good or is it bad and around how much hp should i see using a 48ida carb setup.

 

well i think blow through is alot easier and i think moajority, LARGE majority, of peopel turboing there rotarys are going wioht a blow through setup. your HP will totally depend on you entire setup liek IC or no? how much boost. the turbo you will be using etc..

 

You sure as hell better port it if you're gonna use a 48IDA.

 

nah 48 will be fine as long as it's tuned right. use smaller horns.

 

one more thing, SEARCH!

 

A draw through limits options. You'll be ok with a Dellorto, but since the mixture will be drawn through the carb, and then through the turbo you cannot use a IC. You'll need to keep the intake lengths as short as possible, since the longer length might let the fuel the mixture to become liquid again. This is a typical problem, and makes little fuel puddles occur in the intake housing of the turbo, especially when you'd have the car running too rich.
A blow through will only draw air through the turbo, and therefor leaves more options open. You can use a IC, and a blow off valve.
In Europe (UK) there was a kit developed for the first gen (no longer available) that had a draw through setup. The cars did become very different with that kit installed. It only used a small turbo, and an SU carb. But still managed some good power.
It's mainly a matter of choices, and budget. Of course you must be carefull not to spend more on a good 12AT setup then it'd cost you to do a TII swap that might give you as much power. After all, don't expect 250 or 300hp from a draw through carbed setup!

 

You can definately make some big power using a draw- through turbo. At one stage the quickest untubbed rotor here was in the 9's running a draw-through setup.

I don't see how you could use an IDA as it's a down-draft carb so you're basically limited to a DCOE. It's gotta be big to flow enough air (like up to 55mm) and you need some form of charge cooling like water/methanol injection.

Apparently streetability on these things is a real bitch because of things like heat soak which causes hard starting and they tend to be dogs off boost.
