How and wot....Bolt on more power 1.8
 

Ok if i want to get to about 150 hp.

It looks like I can do this with bolt on stuff,

wot would you recommend..

No supercharger, turbo, just bolt on

I hope you have deep pockets. Bolt on's are pretty ineffective with this car unless you are going with an IRTB setup. If you are looking to get into the 150+ range, boost is the only cost effective way.

You can snag a few HP from a Megasquirt. Unless you have forced induction, aftermarket intakes will rob you of some HP. Exhaust may make your butt dyno feel faster, but gains are negligable. Cams don't do much, but many have had success with the exhintake mod. It doesn't add HP, but shifts the powerband lower so you gain low end torque at the sacrifice of top end.

I tried this when I first got my 95. For half the cost of a NA setup that would be worth anything, you could have a screaming turbo or supercharger setup.

Hmmm. I was hoping that by lowering my HP desire. I could get a few hp cheaper and perhaps be able to understand it and do thework myself.. perhaps not

The following quote is a good breakdown from a well respected Miata racer and builder.

Like I said. Do-able, but not cheap.

DO invest in the Megasquirt. Tuning is an ABSOLUTE MUST for any build. It may not give you tons of power, but you will feel it and have the knowledge for when you do up your HP.

hmmm, unfortunate.. can anyone recommend reading material or video on understanding turbo and its effects hows and whys. and superchargers. looks like if I am going to do this later I am gonna have to learn some new stuff.
I would much rather do the work myself.. but I will have to get a much better grasp on terminology and such

Miataturbo.net our sister forum. Read the stickies, there is more information there than you Probobly know what to do with.

turbo at like 5psi. /thread.



(it will be the cheapest, easiest, and best method.)

Sirbit you are standing on the edge of a very high, very slippery slope.

I hope you base jump off it like most of us did here.

Having a goal is the most important thing in my opinion. Figuring out a plan that gets you to your goal is going to take a while if you want to educate yourself. Read, read, read.

I can tell you that power adders for the Miata are about as cheap as they come, due to the small size of the car. A mainstream full turbo system (kit) or a full supercharger kit will cost you just shy of $4000.

If your motor has high mileage, higher power levels may cause you reliability problems.

For 150whp, an MP45 supercharger kit will do what you want. I agree that getting a MegaSquirt is a good idea - the fuel/timing management that comes with the supercharger kits does the job but not elegantly. If you have any plans to start with 150 and maybe increase in the future... go with the MS. If you want the power and want to spend an absolute minimum of your time and involvement, buying an off the shelf kit is the way to go.

Anything above 250whp would benefit from forged rods & pistons plus a full upgraded fuel system, which significantly increases the cost. Most guys see this as the ceiling for power on a stock Miata motor. This is why having a goal is good - it starts narrowing down the options.

are you advising a thread to read under turbo called "turbo 5 psi"? I dont see one

No he's saying add a turbo, run it a 5psi. Be at your goal with all kinds of room for upgrades.

I agree and I dont plan to waste money to do it.

If I don't understand it, I just won't do it, thanks for your advice

lol, ok I will stop searching,,lol

Heres the deal, I have read alot of information, But very little information is linear, bits and pieces all over. also most of it seems to be explained in terms of discussions between mechanics.

I am looking for turbo 101, 102, 103, doesnt seem to be much of it that I can identify with. lol.. just take my time and go sloooow..lol

First steps would be power goal and budget.
I would suggest a power goal south of 250.

I would honestly be Happy with 150 to 180 and not worry about blowing something up.

budget??? I have no desire to spend 4G's its not that important to me. I would rather buy another Miata with 4 g's

so honestly I dont know, its one reason why I need a better understanding

what you will need to accumulate
Exhaust Manifold
Turbo
Downpipe + full exhaust
Injectors
Engine Management
Intercooler
Wideband o2
Boost Gauge
Various hoses, clamps, bolts, gaskets
I know im forgetting stuff, but a basic list is a good start. the bolded things all have to be in conjunction with each other.
Miataturbo will be your best friend, comb the classifieds for people selling ther kits and you can do it fairly cheap.

Some areas of information for you.

Thanks rtm. That helps alot

some of the stuff in the thread doesnt apply with modern engine managment

this should help, keep in mind it's REALLY old data that i posted years back.


I wwas going to link to the very basic BEGi shanghai kit, but the site appears to be down. that's as intro-base of a kit you can get. would surely meet your goals and set you up for further improvements as you learn.

well it sure does help, thanks fellas,, this is much better than all the floating about I was doin.. thank u Brain

is this it

or this

my friend has the S4 on his brg, with a diypnp. instant spool loads of fun.

I think that these are more like wot im interested in..I love running the the gears all the way to 50mph. but then its like huh wot happened till u hit 60,

I think this will fix that!!! lol

Right ?

i had a blast with the greddy on 5psi, and then i did some supporting mods and cranked it to 10psi with lots of boost sag. according to virtual dyno im making like 180hp, and im significantly faster than my sisters 03 Eclipse GTS, haven't ran with dads mustang recently but i think i will stay side by side with him. good enough for me. :D

yeah, nice!!!!!

that just sounds like Fun!!!@

this was about 4 weeks after i bought the car, still had the tiny 1.6 injectors, had an msd timing box for engine management, i had to go through and fix just about everything the PO did, but it was still fun, 5psi ish run. maybe 150hp at the time.

Yeah yeah.. thats wot i want. Lol.

you could get the s4 starter kit, which is basically manifold,turbo, downpipe. and piece the rest together, you would have to pick up intercooler, megasquirt, injectors, make your own coolant and oil lines. but for that price you could probably get it done for under 3k if you shop right.

good start to your parts collection.

dont really have a desire to spend that on a turbo tbh, i will go with the s1 or shanghai and then see how i feel about it.. i also would like to keep the option open to use as a DD..
If i get a kick out of it, i will likely be open to more improvements. Also as my understanding increases and i am more comfortable with it

As everyone else said, Megasquirt first, then everything else. The Megasquirt will let you make more power and get better fuel economy right away due to improved fiel and spark. You get to ditch the AFM and remove intake restrictions to let the engine breathe better. You can hear the intake growl when you stomp on the throttle pedal once you get rid of that stuff. You could actually do a cold air intake that pulls in cold air unlike most of them.

ok, so i dont need the turbo kit to use the MS pnp? cool

nope forgot to mention that.

Well, I Appreciate all the help, I found a MS pnp on craiglsist, I think its overpriced. ur thoughts?

http://nashville.craigslist.org/pts/2982259597.html

ask questions about how old it is. if the wideband pictured comes with it, if it includes the o2 sensor itself. if not i want to say a new sensor is about 100$
A new still in original package PNP is going for $500 on Miataturbo, an a lightly used lc1 for $120.
so 650 is high, if you could acquire it for under $550. i think you would be doing fairly good.

thanks rtm
