Hey, i have a 1979 datsun sunny with a s13 sr20det manual. I currently blew my t28 on the dyno and when installing the oil feed line on the side of the block it was cross threaded and i did it up to tight and cracked the outside of the block only a couple of mm but i am now pulling the motor out and getting it welded and re-tapped. While its out i am rebuilding the motor. I brought a t28 high flow, what specs i have no idea.

so far i have ordered wisceo 9:1 compression 86.5mm pistons so 20tho over
manley h beam rods
arp main stud kit, arp head stud kit, 1mm mls cosmetic head gasket, front oil pump cover, water pump, gasket kit, timing chain kit + gear, bc springs and retainers, tomei rocker arm stoppers, button clutch

Basically i know i will be limited by my turbo cause i doubt ill get more than 320-350rwhp maybe less at this stage but while its out i am doing it all, and doing it correctly, this is why i am posting this, to see if i have missed something.

I hav a 3inch dump and ex, boost controller, fmic, microtech lt-10, hks camshafts 264 in and ex 10.5mm lift, some sort of ex manifold, bosch coil packs, 660cc injectors, bosch 040 fuel pump. when is aparts the block is getting full machinced and balanced, line honed etc, head is getting cleaned up and also ported. Basically i figure id be happy with anything over 320rwhp, with the higher compression pistons it will be tuned for 17-18psi, and before everyone starts saying i can do this on the standard motor i know this but i will eventually get a bigger turb maybe a 3071 or similiar and maybe get around high 300's and im not pulling it out again, hense the depth in the build. The idea of the car is something i can drive to the track have some fun, 1/4 racing, i have a diesel corolla so i hardly use the datto its my toy, but i still want it to be like a daily driver, so im not going a complete massive stupid turbo that will make it a prick to drive on the road

i was thinking maybe a inlet manifold? maybe a greddy manifold?? they seem to be popular i can get one for $650, but thats expensive, compaired to ones that are like $200, is there really a difference or really i point in changing it for the power levels i want?
i think i have everything covered, but id rather post then over see something, is there something i should add? is there something i overseen?
I added a picture of my car incase anyone is interested.

Thanks for any advice...!!!
