A quick question.
The 6A12TT engine has a pair of turbo's which boost in tandem.
There are inherent limitations to the upgrading of these turbines due to the spacial contraints posed by the firewall on the 2nd turbine (closer to the driver), [not to mention gobs of lag if the turbo's r not sized correctly]
After such discussion, a fren of my posed a question, what if he were to only upgrade 1 turbine, ie the one further away from the driver, to lets say a TD04L (which he has at home from his GSR days).
Assuming there is enough fuel and spark, would there be any drawbacks? ie engine not balanced due to different loads on the exhaust side, uncontrolable boost spikes? etc..
would love to hear your opinions, guys.
p.s. For arguement sake, lets say he doesn't want to go with a customised turbo exhaust manifold. He wants to use the stock manifold.
I'm not sure if the bolt pattern on the flange is identical between the TD04L and TD02. maybe someone knows. Anyway, assuming it can be done, will it work? ie more power? more response?
I think the Efini has different sized turbo's as well. So can it work on a 6A12TT?
