Hi guys, so I am going to turbo my NB2. My power goals are around 240-250whp. I want to stay on stock internals reliably.

I know the efr is a great turbo, but is it with the extra money? If I go with the efr, I will purchase the Trackspeed engineering kit. Price=3k before tax. I will have to wait to save enough money for this.

My other option is the garret gt2560r. If I go this route, I will get the FM manifold and downpipe etc. Price=1700 before tax. I can get this now.

My deadline is the MRLS event in october so I want to have everything dialed in before that event.

I have searched and have not found any comparisons of these two specific turbos on a stock motor. So don't flame me.

250hp on stock internals doesn't sound reliable to me.

if you want to do it once, you wanna do it right, and since the efr is modern tech and 2560 is 80's tech, I'd go EFR and not look back.

but the 2560 is a real neat turbo and should work just fine too, miata's have been running with them for 20+years

icantlearn

What sounds reliable to you?

Thanks for the input!

You'll probably have to get with the fact that you're too late and you're not going to meet your deadline to be at MRLS and be trubo... just saiyan

Get a TSE EFR if that's what you truely want, goto MRLS stock 'now'... show up 2017 SS3 BUILT and bro down.

Miatas have been reported to run many years at 250hp. I blew up an engine at around 230hp. Too much low-end torque around 4000rpm was presumably my problem.

Just accept the fact that even the 6258 will eventually vent the block and pick up my brand new 6758 for a killer price

icantlearn

The 6758 is too big of a turbo for me. I like fast spool. hehe.

icantlearn

But....boost. :(

icantlearn

So what are you suggesting?

Get the 6258. Run at 220hp. Buy used engine or short block and install Ebay rods and some aftermarket pistons while you're enjoying the 220hp. Don't blow up your old engine if you can avoid it. Side-venting the block isn't too bad, even though the sounds it makes are nasty. But setting your pistons free of the annoying tether of the rod will have them impart their kinetic energy onto the valves above. The valves were not designed as shock absorbers and will deform, subsequently sticking out of your head at odd angles.

NAh, YOU LATE TO TEH BUILD!

Which is which?

icantlearn

I have a used engine. Ebay rods?

Then do your build and show me HD Laguna photos... I'll be waiting

the efr comes with a bpv, an adequate internal gate, and a boost control solenoid too.
