Project long overdue( DIY KIT ADVICE NEEDED)
Hey guys.. I've been involved in the miata community for over 2 years and finally have the balls to go buy one for myself and start working on it. Anyway as far as the miata goes.. any NA miata will do.
EDIT********************************************** ****** Okay so heres an update: I've now bought the Bought: 1994 Mazda Miata 1.8 motor (spare) XS Power Turbo Manifold (spare) HKS Turbo Manifold Stage 1.5 Flyin Miata suspension E- Management Blue E-management Harness T25 Turbo: FMIC +pipes+ bov + T bolt clamps + hoses EMB Wire/CD 2.5 inch Exhaust Total: $3635 Need Clutch/Flywheel Injectors Boost gauge Wideband Downpipe SS lines Goal is $5000.00 including miata Alright this is what i've got so far!:bigtu: |
Make sure you step up the injectors so you can at least utilize the potential of the GT28RS. You may want to check out the Megasquirt forum here as well. They are not priced far off from the Emanage but offer a hell of a lot more flexability and control. If you are going to build an exhaust just go with a 3". Every turbo car I have been involved with that started with a 2.25" or 2.5" from the turbo back has picked up well over 20 whp and wtq going to a full 3".
The stock head gasket should be just fine. You will probably get tired of the chirpy HKS BOV. You probably won't like the drivabiltiy issues associated with venting to atmosphere. There are |
Tial does not offer a 38mm BOV, only a 38mm wastegate. They do offer a 50mm BOV and if you are dead set on venting to atomosphere then the Tial is my favorite;) If you haven't picked up all your turbo goodies yet you may want to check out this thread for some pretty awesome pricing https://www.miataturbo.net/forums/showthread.php?t=5352

If I have to listen to the sound of a BOV I will listen to the Tial all day long. Sounds like a whip cracking. Gets my fiance all hot ;)

No its not. Someone did a really good writeup on all the work involved in that conversion though. Crash something was his name.
|
Maybe look into the Mazdaspeed engine and diff mounts to keep everything in place. If I remember right its about $150 for both and makes a really nice difference in the solidity of the car.
|
The engine mounts and diff mounts are around $150 together I wanna say. For sure under $200. You may want to look into a torsen rear diff from a later car as well to get ready for all that power.

Why don't you start with a '94 with Torsen? Then you'll have the 1.8 and the good rear end.

Frank :inout: He said what I was going to say. For what you plan to do immediately, it would be absolutely insane buying a 1.6L... :dancegay: Buy a 1.8, it'll probably cost less too that way. |
First, do you have a horsepower goal? You've listed all this great stuff you plan to buy, but you haven't told us your "plan" yet. What do you hope to get out of this stuff?
Second, a lot of your questions can be answered here: https://www.miataturbo.net/forums/showthread.php?t=4288 Don't forget to read the rest of the sticky's on every page! Third, I don't hear DP. Might as well go with the Begi DP while you're at it. There's nothing better on the market right now. Fourth, The stock tranny will hold up fine. Check the ratios on the RX-7, they may not be compatible with the stock rear Miata ratios... and the stock 1.6 rear will not handle the power we're talking about. You will need a driveline upgrade immediately. Fifth, skip the head gasket, you don't need it. Sixth, boost controller. There's a group buy on the Tullos in the classifieds, can't do better for the money right now. Seventh, consider Wideband. The LC-1 will plug into the EM and make tuning a snap. Eight, gauges. You need a boost gauge and WB would be nice. Don't forget fuel pressure and perhaps EGT. Ninth, don't forget to tell us your goal... and a budget would be nice. |
Skip the head gasket.
Get a matching DP from Begi Upgrade to a Rx7 will get you a cool clutch LSD, but you'll get the same strength from just upgrading to any 1.8 rear. Tons of info on this. Since you are going EMB or EMU you might as well step the injectors up a bit. Yes a power goal & budget would be helpful steering you into any particular direction. I think someone should read my FAQ and just review some of the concepts behind turboing these little devils. |

Okay update. I'm picking up a 1.8 motor that has everything but the crankshaft. Also the guys throwing in an XS Power Turbo Manifold that works with T3/T4 turbos. So that should answer a few questions. As far as the miata itself i'm definately going for the 94-97 as I know they have better rear end and trannies. The torsen was only available with the R package in 94 isn't that correct?

No Torsen on the 93LE. Just the crappy 6" VLSD.

Updated guys check the original post

If you're going with an EMU, get 450-550 injectors. You can pic up a T3 60/48 or t3 60/63 for under $150 with minimal shaft play. Worst casen you sent it off for $150 te get it rebuilt/balanced.
I thought the XS power mani was for a T28 flange? Or maybe a DSM flanged turbo? Anyway, Frank |
What power are you aiming at?
I would forget the fuel pump and go bigger injectors---> 440cc or something. US guys seem to be super keen on upgrading fuel pumps, and i'm not sure why. Buying bigger injectors is much cheaper and gives the same result (to a point). WE NEED A POWER FIGURE... |
|
well I'm more into making a reliably quick car that I can do well in the circuits so power isn't my priority as you can see but I would be very happy with 250whp or around there.
|
The rest look pretty much figured out.. this is what I need help deciding.
