"Ello","did you say hello?"."No, I said 'ello', but close enough".
 

Do to "phillyb" urging from club roadster here I am. I've been in the automotive world for sometime. I have a friend that contacted me about selling his wife's 91 Miata. There having twins, and they purchased a Fit and a Camery. I've never really been into Miata's, no particular reason just haven't. Longer story short I've decided I may pick it up from them. My general plan is boost (want some where near 400hp), hardtop, decent driveable stance, and clean body, with some type of dope lip kit. I almost nothing about Miata's so here I am.

All I hear is "not reasonable" "reality check" yada yada yada, its dual overhead cam motor. 400 Shouldn't be an issue, with a bored 1.8 to say, 2.0 and a VVT head. Am I wrong? A little D series breaks 400 with mild build. Whats up with mazdas not being able to make that kinda of power?

:rofl:

Enjoy the stay

Hawnduh engines are sideways so they make more power. Miata engines point forward.

400 shouldn't be too bad if you've got the money to spend.

i am indeed here. yes.
i don't post here often due to my lack of knowledge, but these guys will point you in the right direction on your build.
as i mentioned in your thread on cr...

built block
all the mods
6 speed transmission
big turbo
and a hell of a tune...

definitely check out this thread too for the basics - https://www.miataturbo.net/useful-sa...ig-post-10821/

and also check out the builds to see what others are doing to reach their goals - https://www.miataturbo.net/build-threads-57/

At 400rwhp, you are going to be replacing everything in your drivetrain, except for maybe the block.

If you're going to be replacing everything anyways, why stay 1.8?

Flyin' Miata : V8 conversions : Turnkeys and tradeins

If you're still stuck on building a miata block into a 400hp machine, I've listed all (most) of the things standing in your way:

come in, meet the misses.

One does not simply, make 400hp with a miata.

Since you didn't get it the first time, the easiest way to 400 HP is an LS1 swap and about $15,000 plus to replace everything underneath the car and that's assuming that you do most of the work yourself.

Fooge03, Thanks That's what I needed a veritable this is what needs to be done list. This Will be a "Toy" not a daily so, I'd like reliable, but forced induction isn't reliable...EVER, theres always the need for more, leading to ka-boom.

At $15000.00 PLUS a LS1, I personally need to be in the 1000hp range. As I stated, I DO NOT WANT A V8, Ill go SR20 before that.

It's probably important to realize that if you are from Honda land that 275-300 hp in a Miata will be way faster then the majority of 400hp fail wheel drive (d series) hondas that you may have encountered

That being said - 400hp is a monster in a Miata and won't come cheap - Be ready to invest a lot of time and money in a huge project -

Quality Control.
