Hey guys,
So I'm planning on bolting up a set of DCOE's to my stock B18, a little tired but with reasonable compression across all four. I have the R sport replica long runner intake manifolds (I realize some fender modification will be needed) and an IPD header. My question is do I go with 40's or 45's. My thought was to just go with the 45's and choke them down as I plan on building a B20 in the future and this would allow for some expansion. I had good success in my aircooled days choking down 44 IDF's to run on 1600-1800cc flat fours so am I correct in assuming that this shouldn't be much different?
Also, I need some jetting guidelines. What chokes and jets would I want to baseline with for a stock B18 assuming I'm going with 45's (if you think 40's are better then specify for 40's)?
This isn't a debate whether SU's or Weber's are better for my application, that's not what I'm getting at, I'm bolting the Weber's on regardless. Any help would be much appreciated.:thumbup:
Also, I'm considering freshening up the B18 a little bit. Is there anything relatively cost effective to spruce the old lump up while I pull off the cylinder head for inspection? Maybe take a little off for more compression? New piston rings?:thumbup:
