WI on my Supra

[supraNA-T]

Hey guys.
I'm new to this forum and looking for some insight on Water/Meth injection.

My car is a 96 JDM Supra SZR NA-T.

I'm installing a AEM WI kit

Now i'm running 1.1bar as max because of my TThg..they say this is about max on 98ron fuel

How and how much would it be safe to turn up the boost on my NA-T Supra

I use a MapEcu2 for fuel and timing control.

Any input would be great
The grey one is mine, and the black is my bosses

It is difficult question to answer without more information. YIuy can rub as much boost provided you have enough fuel, no knock and EGT below 900C.

I know this very general but work on most engines.

Did they lower the compression ratio when they did the conversion?
(Low-comp pistons, thicker head gasket?)

Also do you still run the standard injectors? (440cc/min)

Do you have any AFR figures? We'd need a bit more information to go on :smile:

Yes i'am running a thicker head gasket, lowers cr from 10:1 to about 9:1
and i've got 525 inj. The AFR is 11,5 ish
