Hey guys, I'm going to start buying parts soon and I need help with choosing parts, there's so much to choose from!
My plans have changed a little, and I was thinking about bumping the compression up to 10.5 by shaving the head, and possibly ceramic coat the pistons to hopefully reduce/eliminate the risk of detonation since I'm seriously considering on slapping a GT2560 later down the track.
I'm going to be running E85 as the main choice of fuel, and with the MS3x setup with a fuel flex sensor and possibly meth and water inj, I'd like the flexibility to run RON98 pump fuel when I can't find an E85 station with just reduced boost and timing retard (5PSI instead of 10) via separate fuel/ign/boost control tables and at reduced power of course.
My power goal is 200HP, does this sound feasible? I spoke to an amateur car nut a couple of weeks back he told me I was crazy to boost on 10.5. And yes, I would be crazy to boost on pump gas, but E85 is a whole whole different story! What do you guys reckon?
Gates Timing Belt kit
Hondata phenolic intake gasket
(I've heard somewhere that aftermarket pumps aren't as good as genuine Mazda, this only needs to last me roughly two years/25,000KMs ish, will it be fine?
There will be the neccesary seals, ie front main, camshaft, cas, rear main, half moons etc.. which I'll just source locally.
So I'm hoping that all my spare 1.6's, that best case scenario, the pistons are within spec. So all I need would be a re-ring.
Now onto the bearings and rings choices..
NPR B6 piston rings
ACL Race Main and Rod bearings
(Will I need these or will I be fine with just ACL OEM specs which are more than half the price?
ARP Head studs
and main studs
(again, do I need these? or just OEM spec?)
The motor will basically running 255* reground stock cams with HLAs, and 99% of its time on E85, I also have a set of COPs which I'll slap on to help me with cold start issues on our cold winter mornings, a coolant reroute is on the cards and the turbo intercooling piping and log manifold will be custom fabricated by a good friend of mine.
I already have a new stock headgasket, will that be fine or should I consider a cometic? I will be running adjustable cam gears to workaround the shaved head and timing issues. But all in all, what do you guys think? And what am I missing out on?
