i want to run sequential turbos eventually.
i have a 1987 t2 and i want the power of a single turbo, but i need the lower end for normal driving... i'm used to working on v8's w/my firends and this is their recommendation. how practical is it, and do u have any recommendations? thanks, -jeff |

Seriously, stick with the single turbo design. You will LIKE IT.. https://www.nopistons.com/forums/pub...IR#>/blink.png you will LIKE IT! https://www.nopistons.com/forums/pub...IR#>/blink.png -Markus |
There's a reason why FD guys go with single turbos. https://www.nopistons.com/forums/pub...1047683561.gif

sequential becomes a pain in the ass once it isnt running perfectly
|
oh yeah..... how would you propose setting up your turbo's for sequential anyways?
|
i'm not sure how i'd do it. It was just a quick thought that came out of a night of heavy drinking. What is the typical powerband for a single turbo? because i want to be able to drive this thing normally.
thanks for the advice. |
any of the factory twins wont clear the intake of a t2 motor, so you'd have to do some kind of engine. the fd twins will fit on an fc though. not worth it imo, you also need to find an ecu that will run it and wire it all up

the japanese does it, they put FD intake on it, and put the MAF after turbo.
|
The spacer between the LIM on the FC and the FD UIM costs a few hundred bucks. It's all possible. But is it worth it? Survey says ----- NO!!! https://www.nopistons.com/forums/pub...R#>/tongue.png

A properly sized turbo will boost torque more than horsepower, just look at the 5v audi 1.8t motor
|
I made a few of these FC LIM to FD UIM adaptors, PM me if interested.

Whats sequential twin turbo mean?
How is that any diff than one turbo or normal twin turbos? Basically i understand single turbo and twin turbo like they have on the 300zx, one turbo for each 3 cyclinders. Is this any different? |
Mazda FD3S sequential twin turbo:
primary turbo comes in line from the beginning, lower rpm. Using all exhaust engery to spool only one turbo, thus spools very quickly. once rpm goes up, where there is enough exhaust engergy to spool both turbos, a control door opens up, providing both turbo the exhaust gas, spinning both, flows more air. other common sequential setup: have a smaller and a bigger turbo. the smaller will spool faster, and increase the volumetric efficiency, increase exhaust flow. The bigger turbo will then start to spool when the exhaust energy increases. |
