S52 Swap Question

[cormier]

THR sells a kit with new sensors etc, works out to almost the same cost getting it all separate. That takes care of just about all the wiring if youve got the harness done

a chipped obd1 s52 with exhaust and intake was like 260RWHP

I would think thats an optomistic number.

Highly optimistic.

260BHP = ~220WHP (assuming the arbitrary 15% drivetrain loss). That is around what most OBDI s52's dyno.

Most if not all of the gains come from the OBDI manifold though so staying OBDII but swapping intake manifolds will net you almost the same results.

more like 220-240rwhp for any S52 stock longmotor and stock cams on a real (heartbreaker) dyno. It does not make as much power as the S50us/s52us swap boys like to say it does.

as high as 250-260rwhp is possible with aftermarket cams and some other tricks, full race S52 can be close to 300rwhp but may need rebuilding often.

a stock S54 in e46m only dynos ~280 rwhp (333 hp crank)
