Probably a project for later in the year, but just brainstorming on ideas to boost the ol' KA in the 1969 dime with a T25/28 off an S13/S14. Planning on a very mild setup so i think a T25/28 with internal wastegate should fit the bill. If i can get close to 175-200hp at the factory 7-8psi I'd be very happy.
My main hurdle (probably the same problem with all 510's with KA swaps who want to boost) is the manifold. I'm open to any and all ideas at this point, but i was planning on getting a 240sx (ka24de) bottom mount SS tubular manifold with T25 flange from eBay and see how much I'd need to modify it to make it fit. I have zero welding/fab skills, so any alteration will most likely be going to a local muffler/fab shop. Hoping the small(er) T25 with internal WG will fit as a bottom mount with this manifold with minimal modification. Anyone have any insight here?
The other option is a top mount cast manifold with a T3/T4 flange. I know this has been done many times before, but I'm thinking a T3/T4 might be overkill for what I have planned.
Of course I'll also be upgrading the fuel pump, injectors, MAF, ECU and all that other good stuff.
Looking forward to everyone's input! Thanks.
