Hi, i have a 1.6 with a tdo4h turbo and running 10psi. It has 200rwhp. I am building a 1.8 motor and was wondering which turbo would you reccomend to give the same drivability as my old setup?? I want to make more power, but still be responsive and easy to drive. Looking for around 300rwhp. I use the car for time attack only. It is not driven on the street.

 

2871

 

FYI, 300whp isn't easy to drive no matter what turbo you stick on it. You want to look at either a 2860RS if you're serious about that 300whp limit, or a 2871R if you're planning on making more power someday.

 

Savington- do you ever race at Thunderhill or Sears Point/Infineon?

Your Miata sounds like a blast. Especially weighing under 2200lbs!

 

I've run at every track in California, including Thunderhill and Infineon.

It's a lot of fun to drive, but you'd better be very awake.

 

Alot of fun to ride in too

Here is a few laps in a ~250-275whp miata. Should be around 2300lbs or so.

This one.

 

That's an exhaust manifold manifold. Here at MT.net we bolt a big pinwheel to ours, the OP is asking about which pinwheel to use.

 

If I remember right, it's also a GT2560, making the OP's stated power goal. Should be zippy.

 

2871

 

That looks like the ideal set up. Thanks.

 

2860rs will do the trick and will leave a little head room

 

I've seen many guys recommending 2871 but which one of these do you mean?
GT2871R - 472560-15
GT2871R - 743347-1
GT2871R - 743347-3
GT2871R - 707160-10
GT2871R - 780371-2
GT2871R - 743347-2
GT2871R - 743347-4
GT2871R - 771847-1

The only difference between those different numbers are some of them are the .86AR house and some are the .64AR. Also some come with a 3 bolt and 2 bolt compressor housing and the other ones are the std 3" house for the turbo intake

Most std one tho is probably the GT2871R - 743347-3 if your want a .64 AR
