Questions about mildly building an engine.
Would it be worth it, when mildly building an engine to get the Billet Main Caps and having my engine line bored for it?
Its about a 1000 upgrade, but does it really need to be done? Projected plans so far: -Belfab H-beam rods - $300 -Knife-edge, lighten and balance crank - $300 -HKS Bead Metal Head Gasket MAZDA Miata 1990-1993 ; Engine Code: B6ZE Thickness(mm): 2 Bore(mm): 80 Compression Ratio: 8.72 - $200 -New OEM 9.5:1 pistons - $(?) where can I get these? -MiadaRoaster Billet steel oil pump gears * $300 inner and outer gears * $110 new pump supplied by us * $50 machining * $10 shipping * $470 total Is that all that needs to be done to the bottom end, or should I get the main caps and put those in? Thanks for putting up with my stupid questions! John |

knife edging the crank and billet mains will be useless to you. Also no real reason for the oil pump gears in a "mild" build.
For a mild build you would do well to just get the rods and maybe new pistons only if you needed them. Also while its aparts, new bearings. Beyond that you can start tacking on all kinds of cost for little things you might want to replace. Also, you need to factor in installation costs. |
Go big or go home. Spend that extra 1k and have yourself a beast. are you building this for na or FI?
|
1k isnt going to build you a beast, trust me.
|
If your talking to me, I meant, that "extra" 1k, so about 2k ;)

mild build:
HP Engine Kit Complete Gasket Set Cometic Head Gasket Wiseco Forged Pistons (78.5mm bore) and (8.5-1 or 9.5-1 comp ratio) ROSS Performance Rings Performance Wrist Pins TOGA HP Main Bearings TOGA HP Rod Bearings Thrust Washers Timing Belt Expansion Plugs + Belfab Rods ---------- $1239 you could save a bunch with OEM pistons, higher then OEM qualtiy rings, stock bore and a hoane job; and still have a block that can take a bunch of abuse. |
Wow.....Seriously......Thats hella worth it. Im gonna show this list to my local Motor shop....
|
Where to get OEM pistons and HP Rings? (For a 1.6)
|
gave link above should have it all.
|
:) Who's got a crankshaft? |
ok So far....
I have: Belfab H Beam Rods $320 HP Piston Rings (R3074) $88 OEM Pistons (Topline?) (PAMA9S) $136 Freeze Plug Set (EPSMA9) $36 HP Main and Rod Bearings (TOGACOMBO-MAZ02) $95 Knife-edge crank (Why not?) $300 New billet Oil Pump and gears (I hear its a weak point) $470 Hone? Any body have a round about price? Assembly? Couldnt I do it myself? If not I know a couple guys who could put together an import engine blindfolded. Then I will be doing to the head: Port, Clean, Polish $980 1MM Oversize Valves $400 Valve and retainer set from FM $366 To put it all together. APR bolts and studs. Running 15+ psi on a TDO4 19T greddy kit? Sounds good? Missing Anything? |
build a 1.8. I wouldn't spend all that money to still have a 1.6.
|
Lol, whats the fun of having the fastest 1.6l Miata with a 1.8l engine
|
1.6.....1.8, its really not THAT much difference when you strap on a turbo.

Yea, I'm sure we all get that the added displacement is helpful but a full 1.6-1.8 swap isn't that cheap. The 1.6 isn't a bad motor, and there are a lot easier ways than an entire engine swap to make up for a 20-30hp difference.
besides, a .2 liter upgrade has never really interested me. now something in the way of a 5.0L engine... :D (but again, not cheap) |

it only costs a little more than a 1.6, is like a 240cc advantage, and it gives you the option of using a NB head.....

There is no replacemnt for displacement. |
