I'm at 6000ft elevation (~18% lower power) , 3.63 rear end (~7% less power), no real power mods. I also think its slower with the non oem intake. The gains/losses are well within VD's error, i couldn't get good a/b testing data. So I can only go by butt dyno.

 

Ok. So is the spedo reading low because of the gears? I've never driven a NA car at 6000 to know what that's like. I guess that's the reason though. You sir need some boost!

 

Haha, that's the plan.

Speedo is actually pretty close to actual. It was reading high with the 3.9 rear end, and now with the 3.63 it is within 1mph of gps steady state.

 

I'm shocked that your car isn't rolling backwards down the hill with a 3.63 at altitude!

 

that sounds awesome. Induction noise is my personal favorite.

 

Yeah for boost! What are your plans? How many boost?

 

Basically anything I can get my hands on. I made an offer on the town bicycle absurdflow/fm turbo kit, but it was lower than another offer.

I really shouldn't spend any of the money I have left, since I'm having trouble with a solid source of income, and i need rent money. buuuut, my life sucks so much right now, and boost is the best self medication.

 

Ah. Well when it's time to go fast, I look forward to seeing some boost in your car! I have posted some cheap turbo builds in the past, boost on the cheap is doable.

 

I hope the race cooling gear you have sells soon with the temps going up. Maybe the gopro setup as well since folks are probably going to want those now that track season is upon us!

 

^that would be lovely

 

So Ed helped me price out a turbo kit from GASP Flyin miata... Budget kit without injectors or turbo comes to 2300 dollars, I'll try and source mustang? ev14 injectors? IIRC and get an ebay turbo.

Gunna call fm tomorrow and see what fitment I need.

 

good luck with that. many ebay turbo's have different 5bolt flanges from the standard garrett

also youneed inconel studs
and don't get the crappy FM core that's now made in china, since you can get one for like 50

 

Why wouldn't you just go taco manifold if you're trying to save money and are getting an ebay turbo anyway?

 

Not sure, haven't bought anything yet.

 

I vote eBay taco mani. sr20 turbo. ebay/cx racing intercooler.

 

I heard ebay turbos and manifolds can work and make good power if done right.

The manifold at least is hard to argue with. Very low cost, beefy construction, and bolts up and has external gate support too. If you go that route, I would recommend going external gate since the ebay mani supports it, and external gate is way better anyway. Also opens up a lot more turbo possibilities.

I have an excel sheet printout of part numbers, links, prices, etc for my complete turbo setup I built last year in my build thread. It was about 2K for a 500whp (capable of more) turbo setup for parts. If you follow the build thread I document some of the parts that were changed, modified, etc to get everything to work well and fit right. The only ebay part that actually failed on me was the oil return pump, and I now run a BMW M5 oil pump instead (lol also bought on ebay but it's genuine bmw part) and it's working great.

 

Also the MK turbo setup is pretty much the deal of the decade for bolt on miata performance delivered. I would consider that option as well.

 

This. I seriously do not understand why anyone would bother with eBay stuff in any way when MK exists. Unless he doesn't have the type you need available and you can not wait....

 

Yeah... Unsure why he's not considering that. Maybe because he wants a 'track ready' setup? That was my guess.

I wasn't sure where Lars stood on the 'approved use' for that i.e. if it was supposed to be a street setup and all bets were off if it was used on the track.

 

I have no personal experience with MKTurbo, but a fabricated manifold would not be my first choice for a reliable track turbo system.
