KA24 Engine build, JE pistons, Port and Polish, Full Race turbo manifold

[tunermt]

Recently put a fresh engine into my S13, the stock KA24e had proven its worth after 6 years of boost at the track and on the streets but with an extra engine floating around why not throw something fresh in the car?

Basic engine build details:
OEM crank
OEM rods (vertical smoothing of all the casting marks)
ACL bearings
ARP head studs
ARP main studs
ARP rod bolts
Port and Polish (gasket matched head/manifolds)
JE forged pistons with (skirt coating) about 9:1 compression
OEM valves

Will also be doing a new cam and solid rocker arms shortly (hydrolic rocker arms failing above ~5300 rpm)


Car is currently using a AEM EMS, ID1000cc injectors and Full Race manifold with a tiny t25 and 38mm tial waste gate.


Thanks to the new injectors we will now be able to really push this turbo and see what kind of torque can be made with 20+ psi.

An early graph after the first E tune revision, just need to lean things out a bit more and start adding boost.





**please not the new graph was done in 4th gear VS 3rd gear**
