I got my big streetport motor in last night, and cranked it up today. It started up right away, and held an idle. Its running great, and I cant wait to get more miles on it. I really want wait to wind it out.



Im running a TII MAF, with TII injectors, and its working just as well as the n/a stuff. Apparently, in S5 cars, the AFM is tuned for the injectors, instead of the ECU like S4's. The TII AFM has extra range, so hopefully I wont have the problems with maxing otu the AFM I had before.

that would be pretty interesting!



looks good!

Cool, any pixs of your porting? It started w/o a push start?

When I said it cranked right up, I mean it cranked RIGHT up. It started as quickly as any well broken in rotary Ive seen has. Starts right up every time without fail. I just did a compression test, and got 85 PSI all around. Not bad for only 2 miles on the motor.



Heres the porting.

Did you put the ehxuast sleeves back in?

If I remember correctly mazdaspeed7 is a fan of removing the exhaust port sleeve.

Great job! Keep us posted. YOU MUST BEAT ME TO THE DYNO.

You are correct, sir. I will never build a motor foy myself another way. I like that powerband WAY too much without the sleeves.

i think the fuel maps are the same between the t2 and na, they just put different injectors/afm/map sensor/fuel pump in it

Exactly. And my motor is going to LOVE that extra range in the afm... https://www.nopistons.com/forums/pub...#>/biggrin.png
