Talking Hi All!

Well hello guys! New to MT.net, but not Miatas. Share the same love as many of you, even learned to drive a manual in a Miata! Grew up dreaming of "Mad-tyte-JDM-style-yo", and as I matured, learned to respect the Miata as the unparalleled roadster that it is. Now, with that said, (I believe I am commiting blasphemy here...) my Miata is N/A at the moment . I know right? Do not worry though, it will be soon enough, I just have another goal in mind first. Does it involve speed, hp, and fun? Yes, but without a turbo. I would like to see just how much power I can squeeze out of my engine before I really crank up the grin factor. I believe I am headed in the right direction, currently producing around 145 whp (per DJ) without ever opening the engine. I have a short-term N/A goal of 160 whp (DJ as well), and a modest long-term FI goal of 225 wph. The closer I can get to that before-hand, the easier it will be with the turbo, right? I will post pics later, as I cannot find my SD-card adapter right now, but I still wanted to go ahead and say "Hey!"

Most of the big stuff is is my Signature. The header/high-flow exhaust really opened it up though. I put in a set of Pulse-plugs and actually picked enough several hp and 4 mpg! Let me explain the 145 though. I registered 136 whp (on a DJ) with: Compression problems due to block + motor honey in oil. To be exact, before the oil additive, my PSI in the cylinders was 150,120,90,89. I've heard stories of how bulletproof these engines are... but GEEZ! I've never seen any engine at those levels move at all, and I drove around for 6 months+ just waiting on it to fail so I could replace it (It never did, so I just started the rebuild anyway). Since then, I have replaced the block with one from an 01, not only restoring the compression, but with a 10:1 CR as well. I assumed 9 hp was not too much of a stretch to have been restored since I upped the CR(I will not say added, as it was just being robbed from the beginning). It sure feels like it anyway! But I guess without a dyno chart reading the big 1-4-5, I cant concretely say that just yet. The most recent chart I do have is a MustangDyne reading 121 from a local dyno-day I went too with the bad engine. My friends stock + MSPNP registered a 104 right before mine.

Cool story bro.
You're full of ****. You make nowhere near 145whp
That kind of ricer math will get you flamed real quick here. I doubt you even make 121whp actually.

Those gay mods do diddly dick for our cars.

*edit-
PS: do you like being blinded by ******** with bright hid's in non hid reflector headlights?

Some guy put, on his car:
Aggressive N/A HKS cams (Don't remember the specs, unfortunately)
I/H/E
MS

And ended up with a little under 120hp at the wheels.

AKA: You're full of ****.

The flywheel weighs 10.4 lbs. Let me get my scanner going and I can prove I am higher than him on a Mustang, if that is what he used as well, then he should get it put on a Dynojet. I believe the difference is 12-13%? Thats how it worked out on mine. Besides the plugs, wires, trifecta, flywheel, and increased CR, yes the internals are stock.

Sorry bro, flywheel weight wont do **** for your horsepower.

A heavier flywheel will make your car read lower HP in low gears. If you pulled in 4th gear or 5th gear, it wont make a difference.

Building a high HP n/a car will leave you desiring A LOT if you want to go to a turbo car. High HP N/A cars have high CRs, while High HP turbo cars have low CRs.

For the money you will spend on headwork to gain 2 or 3 hp, you can spend just as much on turbo supporting modification to gain 50 or 60 hp...and your thousands to get your 2 or 3 hp wont improve your 50-60 turbo HP.

I'm still laughing my *** off that he thinks a rebuilt stock bp with intake and exhaust puts down 145whp LMAO

I dont understand how a flywheel automatically turns me into a ricer? My exhaust note is nowhere near ricey... nor do I have lambo doors, a body kit, spoiler, or rev up at every toyota corrola that rides by. It frees up hp, and that is what I was looking for.

I'm not doing any work to the engine that won't cross-over to turbo. The amount of boost that most miatas push is not enough to require the low compression that many people are putting in their engines. You can solve those issues with tuning, not just throwing in another part. I am only shooting for around 225 hp with a turbo, so the 10:1 wont hurt my results. If I were to be aiming higher, yes, I completely agree that the CR is too high.

They come 140bhp stock... I highly doubt I dropped 20 hp by adding parts.

140 AT THE FLYWHEEL

You think you have 100% driveline effeciency?

Those mods probably added 5hp, so youre at 125, at the MOST
