Some prices reduced.

I am especially open to offers on the turbo kit.

 

gospeed81, what is the estimated WHP for the turbo kit?


Thanks for your time.

Here is a good place to check the compressor flow maps:

http://www.squirrelpf.com/turbocalc/

The IHIs are down towards the bottom. The smaller turbo currently on the kit is the first one, the 3991. The two "TBird" turbos I have are an upgrade, the 4219.

The 3991 can support about 180hp before it's below 60% efficiency, although it felt much closer to 200whp. I know I was at the edge of the map.

The 4219 should support at least 230whp, and be much more efficient (lower IATs) while doing it.

 

Thanks for the reply. Nice link as well. Well I plan on picking up a Miata in the next few months. Would you reccomend the 1.8 over the 1.6? (Torsen diff, etc)

(Sorry if this is inappropriate for this thread)


Thanks again

 

Not inappropriate, always glad to help. If this car didn't have sentimental value I would have already dumped it and picked up a 94-95, preferably with a TorSen.

Replacement 1.6L motors ARE almost free, but 1.8L longblocks are getting cheap enough that it's more worth it to already have the bigger brakes, bigger motor, and something besides a glass christmas ornament for a rear end.

The best part about a 1.8L of course is the option of later adding a '99 head on your built motor. Never forget the importance of mass air flow. Your runners and valves are the number one restriction, and the '99 head is far superior.

 

Dont have a MBC do ya gospeed?

 

Actually, I do.

The wastegate actuator rod on the turbo kit is adjustable, so I guess I could let it go seperate, it's like a $15 part though. If you search under my name you can find an eBay vendor, AN AMERICAN ONE, that charges about 3 times what the constituent parts cost, but makes it easy on us that need one (or two) less trips to Home Depot. I started a stupid thread on it, can't remember their name.

 

I have external wastegate setup, thats why I was curious I need one.

 

Thanks man. Didn't know that about the 99 heads. Very good to know. Crap, 2 days ago i didn't know anything about a Miata, so I am learning. Much learning for me to do!

 

I know somebody needs a cheap turbo kit.

All the hardware you need, two upgrade turbos, and BEGi quality.

 

what kind of manifold? is it the regular begi log?

 

It's the BEGi cast IHI manifold. This whole kit is their old System 4.1 kit.

Here's pics of someone else's identical setup:

Here's some pics I took before I installed:

And I have installed pics in my build thread:

The manifold is flanged for the IHI RHB5 turbine housing. Four bolts, different from the Suby IHIs. This is the same footprint as the VJ11 turbos Mazda used in the MX-6.

 

**** I was hoping it was a t2. nevermind

bump good luck

Price dropped on turbo kit again...$850, cheaper for locals, or even less if you only want the BEGi supplied (tiny) turbo. The upgrade VJ17s would really make this kit badass though.

Somebody needs to buy this thing before I'm done with finals or I'm ordering an MSII kit.

 

Wow, that's a deal!

 

Yes, yes it is...and it's only getting better.

Absolute rock bottom price which I will sit on until it sells:

$800 + shipping

For that price I'll even throw in a 2.5" straight through Dynomax muffler.

Kit comes with a lot of things besides the mani, dp, turbos, intercooler and piping:

-Boost gauge (backlit same color as OEM gauges) with vacuum hose and "T" to put in at FPR vac line
-drill and tap for oil pan drain line
-SS oil feed line
-oil drain line and pan fitting
-water lines
-K&N air filter with new cleaning/oiling kit
-eBay Porsche look "turbo" badge, unused, so you can proclaim your newfound awesomeness
-plug to put in whichever IAT bung you don't use, which is removeable if you use both IAT sensor and a water injection nozzle
-all mounting hardware
-fuel pressure gauge and line for people running ARRFPRs
-some random feed lines and vac hoses
-all hardware and fasteners

Basically it gets shipped to you as it came off my car, absolutely ready to bolt on and get to boostin'. There were a lot of things I spent a week chasing down to polish off this kit like the heat shield attachment bolts and mani studs. You profit off my previous hard work.

This kit was dead nuts solid for a year and half, save one repair to downpipe that was more likely caused by me running a static 10* of timing due to a dumb mistake in MegaTune. This causes a lot of heat in the exhaust, but my local muffler guy is really good about those kind of fixes.


You NEED this. Go fast cheap.




EDIT: Roll bar and water temp gauge SOLD!

 

I also have some smaller items for sale:

-T25 SS oil feed line $40
-Bosch recirc BOV with two homemade flange adapter for it $35
-Delrin diff bushings $40


The first two are from a recent SamNavy thread, and the bushings are from TimBroughton

 

Will the oil feed fit a GT2554?

 

bump for an awesome seller!
