Stop with the camp councillor preaching crap nboost. One of the good things about this website is the skepticism. They don't claim every magician to be a messiah and bow down. 18psi has warranted doubt and questions. He never out right flames the dude. He reserved his judgement and was suprised and compliments the guys good work. This is suprisingly civilized for 18.

Back on topic. I'm a dud. Anyone want to explain why good exhaust manifold design reduces det?

Lower EGTs and lower backpressure mean lower cylinder head temps. And a mean no more hot spot cylinders that make you drop timing across the board to compensate for 1 hot cylinder.

EGT... Of course...

I did a bit of reading too. It makes sense. Thanks.

I read page one and the last page.

Did anything change between them in terms of bandaid fuel management, 550cc injectors, and 300 hp on a stock 2002 motor?

Because if not, I predict the creation of a "help me rebuild my blown motor" thread by same OP sometime in early spring.

sincerely,
guy who ran a 2001 stock motor at 250 rwhp for many years.

I don't see what is the problem with the 550cc??????

Well the engine survived all the summer taking it to the strip for 8-10 passes at least a dozen time. We made 20k this summer and beating on it pretty hard, tapping it to the rev limiter in 6th gear at least 25 times

as for multiple years we will never know because during winter we are upgrading rods, valve springs, billet wheel on ct26 and changing FIC for an ms3 because we plan on upping the boost to achieve between 350-380whp.

We will see the condition of the rods in the engine in about 2 months when ill remove them but i'm sure there will be no bad surprise because compression was still 180 across all 4 when we put the car away for winter.

The car may run fine for years, but I can promise that at 250 wheel hp, your rods look like a bowl of spaghetti very quickly. Just plan to replace them if you pull them.

Please...........stop posting anything about miata's. I'm serious, and not even trying to be mean here.

I don't think you've even been near a miata. At all. I don't even know where to start.

Between this and asking why we all can't yank our oil pans like every other car, I see a serious need for QC Bot to bring the ban hammer.

Why would anyone sink a single dollar into a stock rod? I do not understand.

Well i knew that...

I was just wondering what he thought he'd gain by paying someone to shot peen a curvy rod.

This guy is very strong in the running for eggplant award.

I mean really, it takes skill to be so dumb and wrong.

I'm convinced it's some pimple faced retard hellaswag kid driving a civic and thinking all his "knowledge" applies.

As self appointed marketing director for the "Shuiend for President 2024" campaign, it would be unethical for me to endorse another candidate.

Have we derailed OPs thread enough yet?

I apologize fellas, I was typing a reply larger than what got posted above, but then got busy and exited the browser on my phone. Opened my email later to find that it had accidently posted, obviously incomplete. I also saw a few people replied (to say the least) but im not a grudge holder.

*FIXED*

but no trolling here, Just absorbing all the knowledge I can through reading. The oil pan thing wasn't something I thought through long enough, my mistake for sure. It wasn't something I had realized under my car, yet. I have only had my NB a few months, but alas, they are cars, regardless of how many Miata owner's will act they are something totally different, or dare I say.. Better?

Back on track:

I am interested in seeing the power curve of this set up, I feel this type of build reaches that turbo's "sweet spot", all while not having to worry about stock rods.

I'm in for updates!

Dyno plot was posted earlier in the thread nboost. Page 3 if i remember right. I'll post the new dyno plot with the new upgades and more boost as soon as i have time to do them. Im currently pretty busy on subaru project so upgrades should come around march or april.

Yes, I know it was. I was referring to the new curve with forged internals, more boost, etc.

Update

I finally opened the engine to upgrade some stuff before summer.
First of all lets take a look at 300whp stock rods



yep straight as an arrow
I see no reasons why these would have failed in a near future...
obviously we replace them because we are shooting for more this year
