Budget turbo 5.3 vega

[LS1NOVA]

Here are the parts I would use:
Pac 1218 valve springs from Brian Tooley Racing

ARP head bolts replaced one by one if you don't want to pull the engine apart



Turbonetics 7268 with a .96 T4 turbine. Huron Speed has them for around $750. This will make 500-600whp easily and allow a direct swap to a 7675 later if you want 900whp. Lightweight and reliable.

Whatever manifolds fit you chassis. C6 vette center dumps work well on some tight swaps. Weld 2.25" vbands on the outlets.

Use 2.25 hotside tubing and 3" coldside tubing.

Treadstone 1245 intercooler. Yes, it is an upgrade from the typical China 31x12x4 unit although that works good too if you are saving money.

Precision 46mm wastegate.

JGS 50mm blow off valve.
