edmonton,
Im looking in replacing my stock 1g manifold with a slowboy ported manifold. Even unported its supirior to the evo so I think I will get it. Will it bolt upto my small 16g?

Does anyboy have any feedback for this manifold?, should I see around 10hp gain with the ported modle. (I have the rest of stage 1)

yes it will bolt on to a 16g (its a perfect match for the 7cm^2 housing). I dont know the exact horsepower because i did everything at once. We had to get rid of the engine hoist & modify the heat shield because the flange is so thick!
 
i know ppl pushing 500+ hp that use stock manifold. Port a 2g manifold and spend your money elsewhere. To everyone their own, but i am just telling you that you can save money and gain more hp with another part.
 
I have about $4000 set aside to spend on my car between now and spring. so the cost isnt an issue

Also for the j-pipe that your using spyder, does it have abuilt in vacume port
 
LOL nice edit!, 4000... hmmm do some head work... upgrade your turbo.. make sure all of your intake / exhaust / IC / piping is straight. ... AHH you probably know what your doing but i just dont see why you would want to waste all that money on a manifold!!!!!
 
Parts Wishlist3' turboback/o2 elim downpipe. upper/lower ic pipe, GM maf+MAFT, 550's

start there, get at least a 50 TRIM, and build your motor. BAng that money is gone. dont need no manifold!! LOL, im done. If threw in my .02
 
I am prolly gonna stay with my 16g, reason being, I drive my car year round and its a fwd. I have potential to get alot of snow aswell.

I will replace my 2.5" turboback with 3" rnr

the $4000 isnt only for preformance but the overall car
 
Well, I ordered one last week, It's coming Tuesday. Unfortunatly I hafto go wait in front of my old house because that is where they are sending it to, For some odd reason. I got it without the $50.00 portwork to the runners being I could do it for $5.00. Either way, I've seen it in person right out of the package, It is amazing. :thumb:
 
You won't be disappointed, I have one, and it works very well. Plus it won't crack like a ported 2G will. And it will crack, don't let anyone tell you otherwise. Enough heat with thin walls makes that happen. Good luck. :thumb:
 
So it will bolt up to a 14b also?
