Lars has come right out and said that he does not recommend his setup for track use. He's not necessarily saying that it won't work, simply that it was not built with that type of use in mind.


that price for FM bits includes the inconel studs. It's actually $1874 leaving out the intercooler core, turbo, boost gauge and pod, and intake box. Though adding their box back in for $80 doesn't seem like a terrible way to go. Can also cut a bit from the price by dropping the FM heat shield. You can go with stainless steel hardlines (oil & water) for just a bit more.

Wouldn't you just buy one of those SR20 drop in replacements? Either way, some research for a cheap turbo would be required but well worth it, and I'd go this path over that setup in the classifieds no question.

Whatever, I disagree.
He's gonna do what, 1 track day a year? maybe two?
the tubular will have way better spool and transient response, no contest. So 90% of the time, it will be 100% better. And I'll be shocked if he manages to crack it. And I know how he drives, no surprises there.

The rest is almost the same.
factor in the 300 for a brand spanking new sr20 t25 that's already custom welded to work with the setup (which is what it has), and another 80 for core (with welded in tabs, so more like 150) and you're at about the same cost. and the classifieds setup has inconel and upgraded hard lines, and intake box, and shield, and everything else.

I'm not trying to sell you that kit, lol, I could care less, but cannot agree that a FM setup will be better. I like both, but the awethummm thpool thetup is cooler-er

turbofan 05-31-2017 12:36 AM

You really think there will be a perceptible difference in spool? ... What's the point? I mean, an FM Mani with 2560 spools so quick it's almost silly. Just going to a 2554 would be silly spool. If the tubular is better yet.... Wow.

It's just hard for me to support paying for something with zero guarantee or warranty or whatever over an FM setup at the same (or very nearly the same) cost.

hard to say tho. If he is going to do several track days, FM is prob better. But the absurdflow Mani should be pretty stout too.

:dunno:

18psi 05-31-2017 01:02 AM

hustler posted plots showing the difference
does the FM setup come with a warrantee? I never heard of that

Not sure a chineseium cast manifold would be either.

I have not even ran his parts, but from the pictures of his setups I've seen on this forum, and the results of people putting miles on them, and one guy running 12's in the 1/4 many many times with the setup, I think it's a really good street setup. If you're going to drive your car on the street 98% of the time, I think it's a great option. Given his post above, I didn't read that he was looking to spend a fortune to build a baller class race car turbo setup, more like budget is tight and needs boost.

I didn't say I was recommending the taco one, either.

FM warrants their stuff for some period of time if you buy it new, I don't know about used.

I really want to bring my manifold over to the foundry across the bay and see how much to replicate a batch in some nice stainless. My manifold is beginning to show it's age, but I have almost 23k and I have 175 1/4 mile passes on it. Would buy again :bigtu:

turbofan 05-31-2017 02:24 AM

Still not nearly the same as a track day with a decent driver.

sonofthehill 05-31-2017 02:31 AM

I have been in Turbofan's car and I agree.

turbofan 05-31-2017 02:36 AM

:skid:

The MKTurbo kit is an amazing value for what it is: a street turbo kit. Drag racing included, as you have shown.

But the sustained full throttle and heat experienced on track is a whole other level.

At this point, Marcello needs to really decide what he wants and plans. But he has said he wants a track reliable turbo kit. MKTurbo isn't one, and I don't believe tacotaco is either. FM parts with inconel will work.

For reference, here's a frequency bucket plot of my throttle position for a single lap at Laguna last week:

http://www.codrus.com/miata/fm2r/lag...tle-bucket.png

So out of a 1m48s lap (I was being held up by traffic :)), 32% or 35 seconds was at full throttle. If you assume all laps are like this, then 6 sessions * 20 minutes per session * .32 is 38 minutes of full throttle per track day. That's the equivalent of 190 12 second 1/4 mile passes. :)

Here is roughly what you can expect from the "thuper duper awethum pothum" kit in the classifieds?

https://cimg3.ibsrv.net/gimg/www.mia...112cd6140e.png

18psi 05-31-2017 10:33 AM

No way. that looks like poop.

I'd fully expect over 200tq by or before 3k rpm on the thuper thetup. What setup is the above dyno from?

I did a whole bunch of research on that setup, I even think I had a thread about it showing plots of kinda similar setups.

Steve Dallas 05-31-2017 10:42 AM

That is an FM II kit with a GT2554R. The exhaust is unknown.

I agree the spool looks pretty lousy. It pretty well matches other FM dynos with the 2560. Manifold flow?

This 2560 dyno has a 3" exhaust. The scaling is different, but the curve looks similar.

https://cimg6.ibsrv.net/gimg/www.mia...4fee881287.jpg

I take it all back, and I'll see myself out.

18psi 05-31-2017 10:50 AM

Ahh, that's an FM plot, now it makes sense.
The manifold is part of it, but the biggest reason is elevation.

Ed is right, it's not like a gt2560r on a log is lazy or a slouch, I was just dead set on making the BP behave like a big ol v6 at the time I was going go run that setup. I'm sure it will be a hoot for whoever runs it. On a vvt 1.8 with supporting mods I'm sure it will be a riot.

This is 100% correct. I build the manifolds beefy and to the best of my ability. I even get the t3 flanges specifically made to fit the M10x1.5 TSE Inconel studs. Now saying that I sell a $250 manifold and I don't trust it to actually hold up on track with a fast driver. I don't know what will fail, but I without a doubt expect the manifold to fail somehow if you are fast on the track. I bet Savington or BBundy would get less then a day out of it. On the other hand, someone in HPDE 1/2/3 might get a dozen events out of it or more without issues. I could "possibly" build a track reliable manifold, but it would be priced at what Artech charges, and I have zero desire to get into that market. Especially since I think the TSE manifold is the set it and forget it option. I say this with both an Absurdflow and TSE manifold sitting in my garage.

Got it. The elevation issue had not made it from the back of my beer-addled brain to the frontal lobe in this discussion. Good thing my elevation is only 530 feet.

thumpetto007 05-31-2017 11:54 AM

Just to clarify, I won't be doing anything track related for many years.

I want the low cost boosts for the smiles on the street. Just a little bit of full throttle every day. Eventually, in maybe 3-4 years, I'll upgrade again.

Lars' kit doesn't come with intercooler or intake setups, and pushes the cost to the same as full diy FM kit without turbo.

The thuper duper kit on here scares me, since I have been burned in the past with a kit that had changed hands many times. There is also almost zero customer support for me if I buy that kit. 2700 seems steep for this huge risk.

18psi 05-31-2017 12:02 PM

Find a complete MSM setup for under 1k. I've seen quite a few over the years.
That would probably be the easiest and cheapest "temporary boost" you could find.
You could throw it in with everything on your car staying exactly the same, and not needing any additional supporting mods aside from oil feed/drain/water lines, since you already have MS3, clutch, exhaust.
