its not really the large streetport that you should be worrying about, its the intake manifold and the exahaust that you will have worry about after doign a large street port. usually you just port the primary ports as big as u can go and then the same with the secodnary and portind the aux doesnt really help. there is not much to port on the 6 port engine on the secondary plate. with this setup you will be looking at somethign liek 170 at wheels with the AFR at about 13:1. now if u go with a standalone and some nice intake manifold you will be somwhere at 190 at the wheels.



if you really want a nice street port then go with the t2 secondary plates and port those. that will net over 200 at the wheels with a standalone.



or



euro NA end plates have smooth aux port casting and if you port that into one port and connect it at the manifold side as well makign it one big street port with an addition of some nice cutom intake manifold it will equal to some nice power output.

btw if u only have 750 you will prolyl spend all that just rebuilding your motor to stock specs. if you meant u have 750 on top of rebuidlign the motor i woudl reccomned just gettign a haltech or microtech.

Your injectors will be fine for a mild street port if you have them properly cleaned and tested.



www.cruzinperformance.com has a good service. Not sure how quick they are compared to RC Engineering but if your down for a rebuild it should matter.

Are there any problems with removing the exhaust sleeve?

Correction for the above post.





It shouldn't matter if your down for a rebuild.

Good luck. If you only have 750 to spend, a factory seal kit for a 13b is like 800 bucks. Give or take.

The Rotary Aviation seal kit has everything for around $550, including teflon combustion coolant seal and viton o-rings.
