hi all im thinking of building a twin charged A series and just want to kno if any one has done this and how to go about it

nt heard of it beingdone a 1200 but vw has just done, hks used to do t=for the gtir and nissan had a 1980s march and suby had a small thing too i think (might have been just 2 cyl super and peiple turboed as well).

not really worth it for performance on an a12 but if you can why not. we all know of one TT that hasnt seen the day for a bit

ive had a few ideas about it i was thinking of having it setup so that the supercharger switches off when the turbo/turbos kicks in or have the turbo feeding the supercharger vise versa any other thoughts would be a a big help

supercharger clutch driven down low then turbo up high.
4agze supercharger would work ok them t25 or similar higher up. it will need a strong gearbox and internals too

theres a cool 4agze powered 1200 featured on turbophile, supercharger feeding turbo

would be a good place to start reaserch

ive done twin turbo a-series, have a look in my photo album if interested

winki has a pic in it of compound charging just the link doesn't work

In Hot4's quite a while ago, there was a red corolla that was turbo and supercharged. It was from canberra i think, had an all red interior too. Would've been at some of the autosalon's too. The article explained roughly how it was done. Super first then turbo.

yeah there's quite a few twincharged 4ag's around, there was one on ebay recently. HKS used to make a kit.

just thinking about the supercharger cut out switch how would you go about setting this up also the piping for the sc an the turbo wouldnt there have to be a valve of some sort to stop the boost going back through the turbo

The blower would need to work off a relay triggered by a hobbs switch.
