still using odonnell plugs at the moment , they are great plugs and cheap

I'll pick up a 97T and give it a try then. Running a 77T now.

you need to get to sleep frosty



very fine sandpaer (emery cloth) after you rub what you can off with a rag and denatured alcohol

hi!
i want to ask if the n21bf-limited has any timing difference from the n21b except the difference in rear bearing.
thanks!

different crank , it is 14mm instead of the 13mm but it really doesn't make any major performance gains . the good carburetor and better crankcase makes a difference though


the n21bf limited is a sweet engine for the price

oh,i confused because in amain's specifications i saw that it has 13mm crank too.does it has the 24064 carb?

Sleep? Whats that

Thanks!

the n21bf will actually accept a p5x crank (or plus 4 ) and conrod . it has the same carb as the p5xs .

so houston.you can't confirmed if the timings have remain the same for the first n21b,right?

about the plus 4 crank,what gains will have?
thanks!

sport cranks are not the best for high performance , the competition cranks create much more power in general throughout the whole powerband . larger crank intake, larger bore in the crank throat , more efficient fuel release out of the end of the crank . just plain more power do i really need to say more

no houston!no!

monty, i live in az as you know and its 110-115 in summer, i planned on using the dyn 053 pipe and if i liked the run time and power i was stayin with it, and i seen the cost of the od plugs and decided to run those, whats a good one to use with my ambient temp

i think i am done talking about plugs but i recommend odo77 standard and odo77t turbo (oh wait those are vspec plugs )

Hey Houston,
I got a NIB novarossi n21bf 3 port hot mods (not limited) awhile back from a friend in a trade can you tell me what the head should be shimmed at for 20% or 25% also what pipe and plug works good with that motor mod or not

Thanks,

.60 = 20%, .70 = 25%, .80 = 30%

Im pretty sure thats correct. I asked once before and others have also.
