BADR33

hey. for the SAFC cant you tune it to run +or- 50% less/more fuel? so there for you should be able to tune it to run with more fuel to cater for the increased airflow? just hook it up to one afm and run 50% more fuel? i can see the logical part of the thinkin that you will end up with half the signal of 1 AFM. there must be away around it either using resistors or somthing similar. otherwise just go for a aftermarket computer. very nice work tho.

yeah it is strange and i thought it would help it breather better. seems to have helped up top. the extractors definalty bought back the low down torque. but boy dus this car scream its head off. i love the deep sound it has and im happy with the power i have. next time im at the dyno i will either put the factory air intake back on and see if that makes any difference or i will advance the timing a couple of degrees the other thing i might look at is a rb25de intake manifold as it might be able to hold more air/ have better flow then my current one. i duno if it will work. ill just go get one from pickapart. haha an apexi S-AFC is another way of gaining a little bit more power for not too much spent but really the rb20e isnt worth spending money on. if i could go back i would have got a 4dr with a rb25de or det. factory manuals are a pain to find thats all yeah i have been adding the weight with sounds. and as my car is a 4dr its bloody heavy. yea losing the weight is the cheepest but i dont really care bout going fast anymore. you get more looks, well the good ones when your going slow yeah the stock system off a r33 gts25t mspec. so thats factory 2.5" mandrel bent. i thought it was crush bent meaning the flow would have been about the same as a 2 1/4" mandrel but i was wrong. i have had the cat taken out(not required in NZ) and a louverd resonator put in there instead. if i do any more engine work ill just repalce it with a rb25de about 800ish or a rb20det $1500 for a nice one. rb25dets are expencive here. about $2000(basic motor missing parts)+ and you cant really get front cuts here.

i have a r33 rb20e series 2 skyline. i have spent somewhere between 1000-1500 on mods and it is only cranking out 71.7rwkw on a hub dyno. its a dissapointing result but it has made me realise the difference between the rb20e and the rb20de. i think i still have gaind approx 10-15kw my mods are coby extractors, pod and CAI, custom intake pipe, 2.5" mandrel bent cat back running factory muffler(full cat back system from a 25det). i dont reccomend running a custom intake pipe as you lose a bit of torque that you will especialy notice on hills. but you do get a awesome sounding intake i was running on 98 octane petrol on the day. i wasnt running advanced timing but i probly should have been. if you guys can see any thing wrong let me know it sounds nice and still looks stockish. good on gas over 10km per ltr with plenty of thrashing. i can still keep up with a stockish r33 25t on the windy roads. does straight line speed really matter that much? im sure all of us would like to own a turbo skyline if it was the same as running and insureing a NA skyline. i had quotes of $1500 a year to insure my car with full insurance. but im from NZ
