EFR or XIDAS?
 

So I'm gathering parts for my 2000 and naturally I have come to a fork in the road.

I don't want to go overboard on spending on this car, so I have a tough decision to make.....spend on an EFR turbo set up or put XIDAs on.

Car is 90% street car, will see few track days and even less autocrosses. Engine is currently bone stock.

I like the XIDAs for obvious reasons. I like the EFR setup for the headroom it gives for power upgrades in the future. I can enjoy it at power levels the stock engine can handle, then once built, get more power out of it, never worrying about upgrading turbos.

What say you?

Xida, wheels/tires, more power. In that order.

xida. efr will kill transmissions and rods. plus driving crazy on the streets is more fun on comfort and handles. speeding tickets not so much. you also appear to be on stock suspension.

^ +1.
Make the car more capable and get to know the car, then add power. You can learn to become a better driver with good handling and less power.

Suspension first. It makes all the difference. Turbo later.

Even cheap turbos are fun, but cheap suspensions will suck the fun out of every drive you take.

I want Xidas badly.

xida first for sure

a sloppy turbo miata is probably more fun on the street

but a good handling naturally aspirated miata is faster on the track.

+1 on Suspension.

good suspension faster car no matter what. You will get more bang for $$

Powerful car on bad suspension/tires = gets beat around an autox/track by a stock miata with good suspension and good tires.:party: (lol my old turbo 92 was a pos on suspension haha)

For a street car I say turbo.

If the usage is 90% street then why do you need baller suspension?

I'd say the biggest issue with your choice is that the EFR is a lot of turbo for the stock block. I am currently struggling with the same issue. I worry about running my EFR on the stock block, it won't take much to bend the rods.

So if you do choose EFR first, you'll be standing on the edge of a slippery, slippery slope...

Both.

there is about a metric shit ton of things you need to support EFR or any other turbo

like a giant radiator, to start with.

I appreciate all the input, but in all seriousness, I side more with Efini on this. This is a street car, I really have no need for such an uber suspension on a street car.

I realize how baller XIDAs are, but it seems like a lot of wasted money/potential to be used on a street car. My 97 is my beater car and would rather take that to the track to beat on rather than my nice street car.

I know the EFR is a bit much on a stock block, but my collection of parts I have amassed includes rods/injectors/radiator. I'm not opposed to building my engine, but I'm in no rush. One turbo to rule them all is quite enjoyable, plenty of room to grow.

Here is where I'm at right now:

XIDAs with cheaper WRX turbo set up (like my 97, I like it and it's cheap)

OR

VMAXX with EFR turbo set up


I don't want this to be a VMAXX vs XIDAS. This is my personal opinion/choice. Unless someone can convince me the Tein Street Advance is better.

your choice is basically: street car vs race car.

I hated having a good turbo setup on a sub-par suspension.

I still hate having a good turbo setup on a slightly-above-par suspension.


I utterly loathe, and cut, myself for not owning a 1.8L.

I think that's a great post. Similar to the "Why not both?" question, maybe it should be "Why get either?"

Why not a decent suspension + a decent turbo setup? If the car is 90% street and you are not in a hurry to build the block and replace the gearbox and you "don't want to go overboard on spending on this car," I might be inclined to suggest the best answer is "neither."

Better Suspension > More power, and this is coming from a forum that is built around making more power.

Better suspension doesn't effect reliability. More HP does. Argue it. I dare you.

I actually pulled the trigger on this decision 1.5 years ago, and went with the EFR on a completely bone stock suspension street car :). It was really fun. Especially if you have rods waiting, just get the EFR and get your car sorted, and start at 8psi. Move up a psi every month or so and you will probably blow your motor at 12-14psi. During wastegate adjustment I hit 13psi one time, and damn that was a whole new level compared to my usual 10psi.

Deleted "outside the point" comment

that's outside the point.

Xidas/fatcat/penske. I'd rather have baller shocks on the street than a baller turbo. Hell I'm thinking of ASTs for the daily just for the better ride quality.

I wouldn't.

Says the guy who took his turbo off. :giggle:

Says the guy with ASTs on his daily driver :giggle:

Scrappy, you may be right about not getting either, and just going cheaper on both accounts.

I've read how awesome the XIDA's are, but for a guy coming from a stock NB suspension, and from my 97's FM springs + AGX's, it may be better to have blissful ignorance on how they actually feel. This way I don't know what I'm missing, and I'm sure the VMAXX's would still feel like a decent step up. Or Tein Street Advance.......idk I'm terrible at decisions.

And for people worried about blowing transmissions apart, I already have a 6speed waiting to go in. I don't beat on my car as much as others, which is probably why my 170k mile 5speed has put up with 250+whp for 20k miles in my 97. This includes track days, autocrosses, and 1 drift event (I was terrified the whole time I would break something).

I suppose until I drive a XIDA's car, I'm leaning towards EFR.

You are welcome to drive either of my cars again on ASTs if you want to ponder. Why don't you come over right now and drive my car to pick-up some beers?

you better watch your cornhole, once he lures you in, you are not coming out for a few days, and even after that wont walk straight for a week

Is that a cock ring and butt device combo?

I love my xidas all the time, I sorely wish I had power only at the track (street driving is nice and tame). Unfortunately though, at the track I tend to get a little bored between corners simply because it feels like I'm on cruise control with my stock 1.6.

Eh, just get both and be happy

Whatever suspension allows for proper weight transfer off the line and accommodates enough travel for a 245/60/13 slick

and turbo

Edit: why do I even have a miata?

Poor Josh. His little island is flat except for potholes, has no curves, and has barely enough room for a quarter mile blast and a quick slowdown, lol. But he is closer to his home track than I am to mine. I just signed up for Homestead-Miami Speedway on May 11-12 with NASA. Come sign up too and we'll show you what Miatas are designed for, hehehe!

I'm having a blast on a cheap turbo. I hated driving my car when it had a crappy suspension. I only have Bilsteins now, but it is significantly more enjoyable. I wish I could afford to spend the cash on Xidas because I know it would be so much more fun. I don't DD my car, but if I did use it for dual purposes Xidas would make it that much better to live with.

urethal plug.

I am left with questions I do not wish to ask or actually hear the answers to.

Racelands are better than blown stock shit, until the shock shaft breaks in half (better suspension, worse reliability).

Take out the rotary from the RX7 FD, add LSX (more power, more reliable).


/troll

Drove/rode in Hustlers daily.
Looks like my mind has changed on the situation.

Maybe I'll just space everything out so it doesn't hurt so much at once. I still love the EFR idea, but damn, I'm blow away with the XIDAs. Anything that can be that comfortable on the street and still dominate on the track seems like a simple decision.

Still want turbo, but seems this may be a good alternative to add new found "fun" to the car.

You're next, ------.

So it was the beer...

What a relief.
