My SR20 build... shooting for 450whp

[1evils13]

I have a SR redtop with <50kmi on it and im trying to build it for 450whp. IM currently looking into buying a Garrett Gt3076r, Synapse turbo Top mount manifold, Brian Crower 272 cams with springs/retainer kit as well. Going to be going with a AEM stand alone with wideband.Nitrous intercooler sprayer. Dyno tune at Synapse Motorsprots Glenville NY.

.. Also possibly BC Valves and maybe a forged crankshaft if I can find one... is there anything else I should look into doing to it to achieve 450whp? Thanks

what pistons would you use?

I would rebuild my SR. If you dont rebuild it, you will prolly spin a bearing or break a rod and then cry.- New bearings, water pump, oil pump, etc- Have your crank and rods inspected for cracks by a machine shop.- Invest in new dished pistons w new rings- Use stage 2 of cams, retainers and springs( you choose the brand)- New Bigger Injectors and an EMS- Get it tuned- Use bolt ons, intake mani,exhaust mani, bigger turbo and boost controller.

you are aware that a sr already has a forged crank...

I am also looking to achieve at least 400+ whp. Not sure what turbo setup yet maybe a holset.

I got CP pistons, eagle rods, ACL bearings, ARP main and head studs, metal headgasket.

That's all for the block for now, but I would also consider a fpr, at least 750cc injectors, bigger oil pan

[chicos240]

You dont need the bigger oil pan, unless your planning on really tracking the crap out of your car.
