You can build a 400 WHP miata for cheap and it might last for a week. You will have to spend money if you want it to last.
- built engine a must (forged pistons and rods) - head port-smoothing, polished chambers and de-shrouded valves - BE oil pump gears - ATI damper (ill say recommended because I don't have one for 5+ years) - EFR 6258 and solid manifold (TSE or ArTECH) - 3" exhaust - intercooler (precision 650 or 300) - injectors (FIC 650 or ID 700 or more) - oil cooler - programmable ECU (MS) - solid tune There is a such thing as too much power. A 200WHP is fun and manageable, a 300WHP miata is crazy fun and a 400WHP miata is stupid crazy. I'm going on 5 years with stupid crazy. Hope this helps. Edit: Once you are at that power level, then brakes, suspension, rollbar, seats and harness will keep you alive in case stupidity ensues. |
I got sport brakes (and booster) with porterfield pads and ss lines.
I think ebay cast manifold and the right size ebay turbo is a good start. |
I believe you have been "graciously" given solid advice many from people in this forum who have achieved though trial and error the power levels that you aspire to have. If you continue to disregard the advice from them then there is no need to continue posting in this forum. Good luck in your endeavors.

Why do you say that ?
Any mistakes with my build ? VVT engine wiseco pistons 83.5mm 8.6:1 ebay rods BE oil pump ATI damper oem seals oem HG oem bearings id1000 diypnp ebay cast manifold ebay turbo 6spd NB lsd sport brakes, booster and pump breaks ss lines fm1 or fm2 clutch competition mounts mishimoto rad rerout What's wrong here ? Thanks |
Okay, glad to see you are open to suggestions.
The specs looks ok except for: ebay turbo ebay manifold These parts are questionable and are known to fail in the long run. Better to pay now than to pay more later. What about the intercooler? |
I got a good one, if IAT will show a bigger one is needed, I'll get one.
|
ARP head studs would be good.
|
Head studs as previously suggested
Make sure the rods have ARP hardware Skip FM1, go with the FM2 clutch. Don't use ebay; support the vendors who support the community Skip the Mishimoto radiator for the SuperMiata Crossflow (I had a hell of a time getting the Mishimoto to stop leaking) Don't break ss lines, but get ss brake lines (My old goodrich lines where too short in the front, my 949 lines seem are better) I have a set of 949 Hybrid engine mounts (one comp mount, one race mount) that is collecting dust in my basement, PM me if interested, let it go cheap. I don't see anything on valvetrain, though Soviet accomplished a lot on a stock head. |

:bowrofl:
Nah, can't make power that way |

Better to buy a 1,500 dollar turbo than a 200 dollar one that might only last a few years. Besides you can't make serious power without a 4 digit pricetag turbo. Right?

if I go through your thread and quantify all the money and time you dumped on parts that didn't work, broke, or needed modification over the years, the number I'd end up with would probably be more than OP could pronounce |

On the flip side, let's be realistic here:

It won't spool as nice as an EFR, or look as good, or impress as many people with the bling factor, but it will make boost and make power. |
Fast Forward kits make power and boost too, but some of us have higher standards (for good reason)

Just forgot to add the ARP studs, top and bottom, the rods came with ARP 2000 5/6" bolts.
The Mishimoto holds great for a few years now. My SS brake lines are from garage star. Maybe I'll do some porting and springs on the head - not sure yet. ebay taco taco (?) manifold it will be, and the right size ball bearing vband ebay turbo. Thanks Pat Elior |

yes, Pat got 500hp~ with ebay manifold and turbo
