yeah, I took the "cap" of the manifold off and made it one big hole. Then I thought I was going to do the same to that (above) side of the intake, but the runners would have left me in bad shape. That porting looks do-able, but I'm really kinda over it and will probably just pick up the aebs as per JD's request.

 

The aebs manifold is killer flowbench seems to like them but the casting is really really bad aka porting it comes into play again. Out of the box the aebs still needs alot of work though imo to really perform but thats all motor chatter for turbo a quick clean up and go enjoy.


A mill bridgeport owns all for rough cut and alot of blending can get the job done on the gsr manifold but the aebs pricing makes it the more logical choice.

 

itll work fine.

 

skill and doing alot of porting along with trial and error is really where it comes down too. A flowbench,track times back and forth are what taught me what worked.

 

any pics of anything youve ported? Before and after.

Something else Id like to know, can you ---- up a port?

 

i fucked up a gsr manifold, that ---- hurt my build.

 

Practice port work on a garage sale weedwacker. If you have any luck making it chew up the lawn? then you might be able to move on to a more expensive cylinder head. haha. I can port a 2-stroke. Never done a 4-stroke.

 

I don't recommend the AEBS for anything less than 2.0 liters. We recently swapped out my AEBS for the fabled JDM P30. The reason being, during the course of the build on my B17, a good loss in power and an obnoxiously HUGE loss in torque was being seen on the dyno. No matter what tuning was done, we were never able to extract the proper power. Frustration led us to swap it out. Low and behold ALL the power lost from before the AEBS manifold returned with interest, and the engine is now putting out more torque than I've ever seen it lay down in 5 years of owning it. (142hp/110tq) which I know is not impressive, but seeing as how the car has never made more than 105 ftlbs of torque in its life, it's a pretty big improvement. AEBS numbers never exceeded 99 ftlbs. Keep in mind this is a very preliminary tune.

I loved the price on the AEBS, and I should have listened to others who told me to go with something else, as the AEBS was too big for my 1.7. Based on my experience they were right. just my .02.
