Maybe a wade 818. Have one in the car ATM, Sounds nice & lumpy. Had a 1147c in the car at one stage. Now that was lumpy but because my turbo wasn't big enough I had detonation. Talk to a tuner so he can help you decide what's best for you setup. Also because you have a standard ECU that will limit your capabilities.

Should be big enough. I was running a T3 high flow(20psi). But the turbo was boosting out around 18psi making the air less dense & prone to detonation.

guys dnt always go for a lumpy cam seriously do some research a cam isnt designed just for sound purpose theres alot more behind it and can easily be the sole item which will define ur car from making power or loosing power speak to ur tuner and cam guys about the rest of ur set up. seriously a wade 1147c is a big cam and isnt for basic set up cars its dsigned to make power with big boost not baby boost under 20psi

just a question on this....baby boost 20psi - fair enough, i kno theres vls making like 30psi, but isnt 20 psi from a t4 a little different from a t3 makin around 20psi? i kno its the same pressure but say a t3 makin 20psi makes like 240rwhp. and a gt42 on 20psi make over 400rwhp. thats what i meant before thats all. will the t04e thats been rated at 600hp on 20psi or so be ok to run that 1147c cam. i guess i can try it and see. i'll let u guys kno on here the result.

What size rear is on your t04e? Mine with .63 rear and 1147c maxed out at about 17psi and 246rwkw and wasn't worth pushing further because of the heat generated.. That's why it now had gt3582r lol
