Looks good! I may have to look into doing some porting.

Bill, I have to applaud you for your "planning aheadedness." You're a great example to all of us because you rarely perform a mod or repair without planning ahead and designing your work process to minimize hang-ups. You have illustrated how successful a procedure can be if you take the time to anticipate difficulties and develop a plan of action.

I hope the rebuild continues to be a success.



















What'* this brown stuff on my nose? Weird.

I dunno, but it stinks, and my sure feels clean now.

Seriously, Thanks.
I don't like failure. I'd rather have the job take twice as long as long as it'* successful. I don't mind spending half on planning, half on the work. The beauty of it is that once the first one is done, nobody else has to spend the time planning and researching.

I have about 4 or 5 hours invested in this total time now. The MAF support porting and polishing, as well as the throttle shaft porting/modification.

Nice work, Bill. I would be happy if I could find the time to just "clean" mine

I sure wish I could get free spindle time at work... those intake adaptors would be ready to ship by now!

looks very nice... very nice indeed.

Nice work Bill...as usual

I'm thinking though that you're going to need an AFC to tune that. I have no experience with the Series I TBs, but the the 97 Series II TB has a similar pedastal for the MAF and for those that removed it found themselves to be quite lean. I've seen people running AFCs at 103 to 104% with this kind of mod.

On the other hand...what a teeny tiny TB you have there :P :P

Cheers,

Awesome! Can you monitor the STFTs and LTFTs with your scanner? Do you have easy acces to make further changes to the MAF table?
