I didn't think of that.... Good thinking!

And if you can make almost 500 hp on this thing... I am sure it will be perfectly fine for my modest goal of 250ish.

please don't make silly blanket statements like this because some n00b will open this thread years from now and make a really stupid conclusion based on it.

It's pretty silly to compare his compound boost franken-setup on e85 to your basic Miata turbo setup

Making 500whp for 2 weeks and a few drag passes does not exactly say how long term reliability will be. The 1.6 tacotaco has been shown to crack after sometime on a real track. So I expect the 1.8 will possibly crack when also driven hard after some time. Now saying that, I still think they will be ok for 250whp on the street for a good long time. And honestly at $80 if it does crack you just buy a new one.

Well there is no way to guarantee long term durability on ANY new part. It takes time.

That said, so far this manifold works fine, and I'm probably pushing it harder than anyone else is currently. And as mentioned, if it only last a year or two, I'll buy another and keep going at this price. My car gets drag raced and street driven, so since I don't do long track sessions it will likely be fine for years on my car.

It seems too many people like taco's, the tacotaco went up in price by $35

Glad I got mine when it was super cheap

E85 isn't quite as warm as gasoline.

There is a very good chance that this wont be around again when yours cracks. I would stockpile a couple if I were you.

yep, he's right

I disagree. 1.6 tacoburritto has been around on and off since 09 or later.

aidandj

iTrader: (5)

Yeah, on and off. Pat doesn't wait around. What I mean is that it isn't always available. 1.6 was down for at least 6 months last time. I didn't mean it was going to disappear forever.

oh yeah we all love waiting a year to drive our car again

Looks like these are currently only available with T3 flange. Without any idea if/when they will put out the t2 version again would there be a way to convert this from t3 to t2 that isn't destined for failure?

Sounds like the exhaust outlet size may be the same between the T2 and T3 versions based on shuiend's post? I know Ive seen some people locktight studs into the holes, then hacksaw them flush, then tap new holes in the proper flange layout. Also have seen people weld a T2 flange over the existing flange. I have no idea if these are viable options or just an option when you are in a pinch. Would also be concerned about possible complications if the exhaust outlets are different sizes. I wouldn't want to create a situation that results in turbulent airflow.

The outlet at the flange are exactly the same on the t2 and t3 tacotaco's. The only difference between the 2 manifolds are the locations for the the stud holes. I don't think welding a t2 flange is a good idea, as welding to cast iron is hard to do. The screwing in studs and cutting them is probable the "best" method, but I honestly don't think it is a good one.

The real solution would just to be buy the t3 manifold, and the t3 turbo I use, then cut your rear shelf some and build a downpipe.

I would agree but i already have an SR20 T25. Which based on your other pictures seems to fit nicely with the FM downpipe. So the perfect situation would be to find one with a T2 flange.

I guess you'll have to wait then

shuiend

iTrader: (24)

Yep I think waiting is what you will have to do. Honestly mine is sitting on my garage floor being used as a door stop, but I won't sell it because one day I may actually use it.

On another note, did you ever figure out if there were clearance issues with the SR20 T25 and the full FM downpipe?

shuiend

iTrader: (24)

Top part of the downpipe bolts on fine, the bottom section looked like it lined up good with the exhaust, I did not really bolt everything together though as I was lazy. You may need to trim your shelf near the shock like all other FM/Begi manifolds.

Opt

The Begi downpipe lines up perfectly with the tacotaco. It bolts straight up to the cat, no modifications, no clearance issues. I am also using an sr20 t25. Not so sure if the FM downpipe will fit, as i believe the tacotaco design is taken from Begi.
