I do wonder how much the std and a modified et head could do for sure.S13EATER could probably shed some light on it when he comes back from holiday.

thats the bloke pukka that i met and seen his car a few times at the pod his a bit of a regular at the pod like myself when i had a the orange s12

i'd say about 330bhp, i still need my cam timing in and there's another couple of things i'am going to try, its still going strong, but the fj is well under way so maybe someone would get there self a bargin and buy the engine with the forgies, headwork, t34, top mount exhaust manifold, plenum and god knows what else its had done.

FAO S13 Eater,

hiya mate,

did you ever get the CFM flow figures for your 'before and after' ET head? I remember your current head is somewhat trick aint it? or does anyone know what a stock head and a flowed head figures are?

hi craig, the so called ported SE head flowed 85cfm, mine flowed around 94 cfm, but that was with only a 81mm bore adaptor, it would have flowed more, but andy @ amt din't know it was a 83mm bore until i showed him the s12 manual.

cheers Shaun and Sideways.

i have a spare head kicking around and was thinking of getting it done for next year. Im collecting bits at the moment for a tublar top mount and elbow.
Whats the pros and cons of tubular elbows (of the turbo rather than arm variety

)? i have one that has a seperate wastegate dump pipe that reconnects to the elbow and thus exhaust gases about 6" later. In power terms, would i be better off making it connect further down into the downpipe? or maybe make into a screamer pipe? Only interested in performance gains, not a cool sound. How loud are screamers? wonder if they will pass circuit sound tests?

my screamer is fairly load, so you maybe best using one that joins back in, although if you used a large external wastegate with a large screamer pipe, then it would probley be less noisy.

the SE one was 75 cfm not 85 cfm, i went to AMT and had him look up the graph.
