YOU COULD SPEND A FORTUNE ON THE HEAD, PEOPLA MODIFY HEADS TO GET BETTER FLOW, IF YOU HAVE A TURBO, INCREASE THE BOOST WILL YIELD MANY TIMES MORE POWER THAN HEAD MODS AND IS CHEAPER TO DO. DO THIS, IF YOU HAVENT ALREADY,
1. SHORTEN WASTEGATE ROD(DRILL HOLE NEXT TO OLD ONE) THIS WILL YIELD AT LEAST 10PSI OR GET THE VBC FROM HKS.
2.GET A BLOW OFF VALVE(OR CLAMP DOWN THE STOCK)
3. GET A REAL EXAUST
4. GET A REAL AIR FILTER(K&N)
5. USE INTERCOOLER OFF SUPRA OR CONQUEST, PLUMB IT ON AND RUN 12PSI BOOST
NOW YOU HAVE ABOUT 265BHP, THIS ALL CAN BE DONE
FOR LESS THAN 800 DOLLARS, ABOUT WHAT YOU WOULD SPEND ON HEAD WORK THAT MAY YIELD AN EXTRA 20bhp
Thanks for the info .I have a boost controller would this this mod do the same as a controller.I was just wondering if some one with a different head, with it stock, and the same mods made to the car would my car be faster or slower than theirs just because of the head.
