Hi everyone i am very new to the boosted scene and am currently trying to piece together a turbo kit and i’m currently looking at a cx racing 53/60mm t28 turbo, i’ve been told by some it will spool slow and some said it would be fine can anyone shed some light? i am running a non vvTi 1.8 engine with stock internals. i am also planning on using a speedy efi ecu to control everything if that matters.

 

"Perfect for any 4 Cylinder"
"Our products are developed at our US R&D center with state of the art Equipments by Experienced Engineering and Racing team, fully tested with fitment and Performance. Dyno and track Proven."
"Buy with confidence. We own many motors and chassis for R+D. Also sponsor many motorsports. Products are fully tested"

With statements like these, how can you go wrong?

 

look ik it’s a cheap *** turbo i’m 17 and broke lol i’m just looking if anyone has had similar size turbos on a miata and how they fared.

 

They can be a bit of a gamble and unless you are getting something from a place like MKTurbo that has a decent supplier...you can be SOL if you have problems. If they are a known clone, you can use any off the shelf rebuild kit. If it isn't then you are screwed if the oil seal on the exhaust side dies in 1000 miles.

Try picking up a Garrett GT2560R, you can find them used if you are on a budget. Good spool in a 1.8L engine and enough top end to blow up both your engine and transmission if you do it wrong. If you want faster spool and don't want to run the engine/tranny on the ragged edge with the turbo pegged out, go with a GT2556R. Smaller compressor side and should keep the power right under the limits of the engine and transmission. Both are great turbos for this platform, I'd go with the 2560 and keep the power in the low/mid 200s HP/TQ,

I have the exhaust-side of those turbos in my Fiesta ST with a modified compressor side; had a mechanical issue one day and overboosted to ~45 PSI absolute feeding a 6000+ RPM 1.6L ecoboost. ECU slammed the throttle body shut and enriched the AFR to compensate, turbo still lives to this day after another 40k miles and still makes 300 whp in the right weather.

If putting together a Garrett based setup is too much for you, look at MK Turbo's website. Their kits are the best on the low end of the market, last I checked. Certainly better than all the ebay trash I see. Just my 2 cents.

 

Do some searching and reading what other ebay turbos people are using. That one is .86AR, you don't need that big of a turbine housing for a stock engine.

 

Just like others said....dont go the cheap route do it right. Im sure youre broke and 17 we have all been there but take our advice and get a 2560 it really is the best suited turbo for a miata with a stock motor and has room to grow if you build it down the road.

 

I can recommend a second hand TD04.

 

This is also a decent option that I forgot about.

 

The turbo is rarely the most expensive part in a turbo setup. Just sayin.
