Hey there,

Recently, I have come upon two turbo kits that I am interested for my 1995 Miata with a1.8L engine. Interested if anyone has any suggestions or tips

1: Garrett GT3076R, artech turbo kit with pretty much everything including a mspnp2 except the midpipe and the muffler, wondering how much it would cost to get one custom made 3 inch?

2: MKTurbo DIY Kit with CXRacing intercooler, brand new

I have questions about running the GT3076R on low boost. My goals are only 220whp, stock motor, stock transmission, upgraded clutch.and radiator
The GT3076R is a big turbo and I feel like its overkill for my needs. Will it have lots of lag if I run it at a low boost setting, like 5psi and will I have any problems like boost creep or anything?
If that kit, I will get a magnaflow 3inch muffler and have a muffler shop weld a midpipe on

Thanks for your time

 

It'd be worth mentioning if you plan on having a built motor or simply turbocharging a stock motor.

a gt3076r for a goal of 220 hp is overkill
a gt3076r on a stock motor is a bit wild
a gt3076r for the purpose of running 5psi Is a bit counter productive

I'd be looking more along the lines of a Garrett 2554r/2560r. The gt3076r is just really more so for goals well into the mid to deep 300s

 

2560r at 11-12psi will get you 220whp.

 

Between those I'd pick the mkturbo kit. It's a good kit that includes the 3 inch exhaust. Search, there are hundreds of threads on which turbo is best for these cars. If you look at the available prefabbed kits you'll find which turbos are the most common.

 

3076 = generally no boost before 5000 rpm, depending upon spec

 

Any recommendations on what t3 turbo I can get that is smaller?

 

I would listen to what others have said on here.

The 3076 size turbo is a great turbo, just very wrong for your goals. I can tell you from practical experience as I've run that size turbo in chinese version and was very pleased. I have even swapped to the larger gtx3576 churbo, but my goals are very different from yours. For what you want I would be looking for at most a 51mm or even smaller compressor inducer.

 

The turbo from the MKturbo kit.

 

Borg S475 for all the boost lag

 

This. Buy one from Lars. He tested several before choosing.
