But I was probably getting ~225whp on the right day when I twisted up the mbc on the B6, how close was I to failure?
My point is really more this: It's not a simple cheap swap like everyone makes it out to be if you add up the costs, especially if you have 1.6L components already. If you're going to bother swapping, you obviously want more power, so why would bother swapping in the lesser of the 1.8L components. Surely you can toss a cheap block in there, but you're talking a 3-4 hundred bucks for a motor and then the $100 swap kit in the least. And you're still left with a stock motor that people love to bend rods in at relatively low boost levels. If you're looking for the best setup, yes, the 1.8L is the better platform by far, there is an overwhelming scientific consensus of this fact. But IMHO don't see the cost:benefit for power levels under 230-250rwhp a 1.6L can do it if setup properly, just not as well. If you're going to build a motor, you'll be silly not to build the 1.8L as well, but just don't expect it to be "cheap" like everyone makes it out to be. What's a good '99 worth nowadays...$4-500? |
check my build thread for my receipts from the engine builder. It appears that I got a really good deal. Then 400 for my 99 head, 300, rods, 350 pistons and rings, 300 for 1.8 turbo mani, $350 invested in six speed (I hope it works), 550 injectors cleaned and flowed 130, donor motor for 600 (which included a FM swap kit, ACT xtreme pp and clutch), billet oil gear 100, begi thermostat reroute housing 100 (after shipping), still have to buy water lines, oil lines , fluids, miscellaneous
I will reuse my DP, try to sell my 1.6 FM manifold for close to what I paid for the 1.8 begi, sell my garrett 2554 and replace it with a china 2860 (keeps cost down) Sure I'll recoup some of my costs by selling left over parts, but this was starting with a turboed 1.6 making 210 HP |
I have a '99, but the 1.6L is a much "nicer" motor. The '99 sounds thrashy and agricultural, where the 1.6 is a lot smoother and zippy, more like a 4A-GE. The 1.6 has some low-comp piston options at low, low OE prices, from the 323 GTX or an automatic Miata.
Miatas are great because they are really good for how much they cost. So keeping it cheap, simple and fun is smart. If you think you'll have the discipline to be satisfied with the simplicity, low cost, fun and good-enough performance of a moderate-effort 1.6L build, it's the way to go. If you think you'll follow Savington and BBundy down the rabbit hole, definitely start by building the 1.8 you'll eventually want, mixing and matching blocks and heads as discussed above. Do pistons and rods the first time, so the stock ones don't take out the block, crank and head when they let go, forcing you to start all over. |

Oh yeah i did notice going from standard bore to 0.040 to 0.060 it got to its peak hp a little quicker in the powerband eachtime
...so going back to the root question adding displacement is always an advantage if i had to do it again, id go from 1.6 to 1.8 first then modify .if anything it would be the same power, less effort. |
that's a cam and IM issue.

seeing peak HP earlier....means the torque is falling off faster, which is a cam and/or IM problem.
