just purchased 95 with BEGi-S (pics and ?s)
 

I flew out from OK to CA to buy this car on Saturday and then drove it all the way home. It's basically a stock 95 with the BEGi kit and magnaflow exhaust. It will be my daily driver/occasional weekend warrior.

I'll start with the pics :)

Since the car will primarily be my daily driver, I'd like to keep it as reliable as possible, while still maintaining a good bit of power. I read the FAQ and many posts but I'm having a tough time finding info for the 1.8s. Almost everything i read seems to pertain to the 1.6 only.

From the FAQ it sounds like if I stick with my stock ECU I'm pretty much stuck with the stock injectors because of my MAF. Is that correct?

Will race gas (unleaded 101) allow me to run more boost or will it only allow me to advance my timing?

It seems like the BIPES units are selling pretty cheap in the classified section. Should I even bother with the BIPES or should i go directly to something like MS?

I'll be purchasing a FMIC soon.

My goal is a car that will reliably give me about 8psi of boost. Right now its running about 5.5 psi with an occasional creep up to 6.5-7. I think that extra pound would be all the power i need for a DD.

For days when i hit the PCA or BMWCCA events I'd like to be able to get a little more power. On these days I'll be running 101 octane fuel.

What do you guys suggest? Thanks!

Bipes will help out your low end. but if your going with a intercooler your going might as well get injectors and ms and unleash 200+ hp. This will allow you to run lower boost for your DDing and when your up your boost for when your go auto crossing.
i dont think you need 101. theres plenty of people pushing more than enough on pump gas.
Thats a nice and clean ride!

get rid of those ugly ass tail lights first and then worry about boost ;)

I made sure the stock tails came with the car :)

I like those hubcaps. Seriously, they do look good on the car. Get MS, IC, and injectors.

i'm fine with the hubcaps for daily driving. It adds to the sleeper theme. Other people have given me crap for them but it's not that big of a deal to me.

How much better is the mspnp than a normal ms system. I think i read that braineak sells some pre built ms units. Is that true? What's the difference in what he sells compared to the pnp?

I believe his is not a "full" pnp. it does pretty much everything the pnp unit does but does not have AC control or idle control (not 100% about idle, correct me if im wrong). you can run it as a piggy back. with your stock ecu.

Just out of curiosity has any of the bracing on the underside of the hood been cut? When we installed the begi kit on my friends 1.8 there were some clearance issues and the hood bracing needed trimming.

No, the underside of the hood looks 100% stock. Where was it having clearance issues?

clearance problems are form car to car... not every car has it

The hood was hitting on the crossover tube. I guess it is possible that his motor mounts raised the engine.

Injectors and MS, this will allow you to make a lot more power. Water injection or an intercooler should also be added. High octane fuel is a good thing, but in this case intercooling and megasquirt will take you to 12-15 PSI on pump gas and to the limit of what the stock transmission will handle without blowing up.

Not necessarily. The Xede runs with the stock ECU and MAF, but you can run up to 550cc Injectors and control timing.

Hope the trip home was uneventful!
Stephanie

Yes you have many options
MS via Braineack 550$
MS Pnp 700$
Exede 800$
Used link 500-800$
EMU 500+ $
So read up on what you want they will all do it, quite well. For the 1.8's most of the 1.6 tricks work just fine. GL man, and thank you for actualy searching abit before throwing the Q's out there and assuming we would hold your hand through it. :D

It's the FM 5 Lug conversion !!! SWEET !!!

I'll give you 20$ for those mad altezzas!! :giggle: Seriously... plus shipping? :) I have an evil plan.. ;)

Attachment 214413

FRIED RICE? :giggle:

Nah nothing too destructive hopefully.. I wanna try and make some cool tail lights ;)

I :dunno: I like altezza's :p

please tell me those arnt the 5 lug hub caps from the auto store....

You also like the -----invader body kit.. :hustler:

Just messin with ya mang. :cool:

I have always wanted better looking tail lights. I think the hour glass brake light is ugly. It should be the circle around the reverse lights. I want a set of those tail lights so I can lamin-x the clear red and have nicer lights.

Car looks good. Looks like it should make a fun DD. Steel wheels are nice, if one gets bent they are cheap to replace. People usually don't steal them either.

I like body kits to when done right.

I briefly looked into the Braineack MS and found this price list:

o Base MS with Miata Mods and db37 connector ($310)
o AIT sensor with 3/8" bung ($30) (for AFM removal)
o EBC includes GM boost solenoid ($50)
o KnocksenseMS ($115)
o 4-bar Map sensor ($70)
o Fan Control ($5)
o Idle Control ($5)
o Piggback Boomslang Harness ($75)
o Standalone Harness ($45)
o Insured USPS Priority Shipping ($15)

I'll be going the piggyback route so i can eliminate the standalone harness, idle control, and fan control, correct?

What else can I eliminate from that list? What did your $550 product you quoted consist of?

Is the knocksensems worth the $115 dollars?

I would say so. It is much better to have the sensor adjust the timing instead of hoping you hear it before you detonate your engine.

sxevegan check your PM Box.
Thanks

I would have more respect for the steelies that are behind em

Sorry Mike, I don't have enough posts to send you a PM reply. The clears are still in the car. I will try and change the lights out tomorrow and will get back to you.

Does that mean you don't want to buy them?:hsugh:

550 was a ballpark figure of what most people pay. When it is said and done. WB o2 is 170 or so depending on what you want. I only payed like 300$ for mine from ADbradley, cuase he is just a cool guy like that, and i feel it is easily worth 500$ for a MS unit they are that nice.

Get a MS, you will thank yourself :)

Congrats on the purchase, I guess its a nice base to start off with. Black NA's rule

I find it amusing that a straight edge vegan drives a turbo miata. I don't know why, but it just seems wrong.

at least the miata doesn't have leather seats like my m3 did :)

and to top it off...im a republican!

Start posting... LOL

OK :)

Like i mentioned before, sometimes I get confused with the capabilities of the 1.8 and the 1.6.

I read that 5psi on a the 1.6 with stock injectors can od 5psi and the 1.8 injectors can do a little more. Since my car is the 1.8 does that mean my injectors are capable of more?

I'm worried because occasionally my boost creeps up to 6.5 or so. I'd really like to get the car paid off (it's the only debt i have) before I start spending serious money modifying it. I really haven't spent much time in boost since I bought it. I'll do an occasional short pull through 1st and 2nd but I'm a little apprehensive about the boost creep and running without an intercooler. My timing is set at 4*.

I guess I'm asking what the biggest limiter is on my car right now. What is being maxed out at 6 to 7 psi of boost? Is there any way I can check the duty cycle on my injectors without spending a ton of money?

When I had a DSM I had a free program called MMCD that would run off of a PDA. I bought a serial cable off ebay for like $10 and was able to plug it directly to the diagnostic port. MMCD would tell me my injector duty cyle percentage, knock, rpm, O2, etc. Do they offer anything liek that for the miata for a low price or am i stuck buying a hole engine management system?

You will be stuck buying MS. You can get MS up adn runnign for about 450$ if you do it yourself and that includes the lc-1. With MS you can use your pda to tune, tehre is a big thread about it if you search.

As for your duty cycle you are maxing them out. I have a 94 with more or less the same setup as you except and intercooler and I am running MS. I am maxing out the stock injectors at about 4.5psi. With runnign the BEGI FPR you probally have some wiggle room for the 5.5 to 6psi.
