My goal is +300whp.

Sounds like a good plan. But I have to ask, with such a strong engine you're building, why shoot for only 250?

Nice, in before allofit

I'd like to keep breaking things to a minimum. 250 is well documented, and will be easy to get without much effort.

Are you getting boost creep (or was Kotomile getting boost creep) with the BEGI downpipe and 3" exhaust on the Greddy? Considering the same downpipe but have seen that some have had issues with the SG downpipe when using an IWG.

You'd have to ask him. I can tell you once it gets here, but who knows. The ETA was July 2nd lol... so much for that.

Not sure if this is relevant but I'm using an Artech 2.5" SG downpipe on my Greddy set up with absolutely no boost creep with a 3" exhaust. Stock wastegate actuator, though it seems to be holding up significantly better than most Greddy wastegates I hear about. Holds 10 psi all the way to redline with the wastegate sourced post-IC. It did creep quite considerably though with just the Artech DP with no exhaust.

That's consistent with what I've read elsewhere. The ARTECH SG supposedly isn't as long as the BEGI SG. In one thread I saw someone claim that they fixed creep on a BEGI downpipe by shortening the SG section. Can't remember if that was a Greddy though.

Anyway, my take-away is that there are no issues with the ARTECH design (assuming you run an exhaust, LOL). Hopefully, FRT will get his car and answer for the BEGI design. I'll also PM Kotomile (assuming he's still on here now that he's a gentrified NSX driver).

I want to get either the ARTECH or BEGI, but prefer mild steel so leaning towards BEGI.

Sorry for the threadjack -- back to regularly scheduled programming . . . .

No issue with the garage pic lol, it's messy and I know it.

No creep. Some spike initially, but not terrible. Adds character. It's running a Garrett (FM1) WGA instead of the party favor that comes with the Greddy.

It's actually not a bad thing that you're ditching the Greddy. It's a pain and a half to take on and off of the manifold, and the design of the return pipe almost guarantees that you have to replace the top section of the return hose every 6 months or so. I've worked out a lot of its kinks but it'll never be perfect with a Greddy. :)

I honestly thought about just getting a 1.8 mani fabbed up for the greddy and using it on the 1.8. But it's hard to justify that :/

I really haven't given much thought to what I'd replace the greddy with yet though. I'm not trying to run "all of it" but I'd like to have boost hit early and hard.

haha glad you don't mind me posting that :D I love that pic, look at it every morning for at least 5 minutes. I think that is the perfect representation of what a lot of miata garages look like.

That is a nice looking car. Good luck with it.

It looks a bit more like this now:

lol

hahah nice koto!

I should mention, 250 is only 10 more hp than it's making now. Would probably have a lot more meat to the powerband with the larger displacement and lower CR though.

Yea that is the plan. I think that I can increase the power just about everywhere. 250 is just a goal, if I happen to make a lot more, I won't cry at night :D

That garage looks perfect for a turbo Miata. Not so much for an NSX. Where's the shiny floor and Gray Poupon?

:rofl: title change.

Whatever guys, mark my words. This one stays.

Grey Poupon, lol.

I'll do tiles in the next garage when I move in February back out Californee-way. Not worth it to lay down epoxy in temporary houses. :)

LOL, the title change cracked me up. Good one mods.

I'm subscribed for driving impressions of koto's car.

Also, koto how do you like your NSX vs the old miata? the miata @ 240whp HAD to be faster.. right?
