Hey guys I have a turbo 1.6 running 10 psi but she's giving me trouble. I'm looking to upgrade cars and I was hoping you could provide some feedback.

I have been looking at BMW Z4M's and Honda S2Ks but I can't figure out what I want. I love power and speed but I also appreciate the nimbleness of the miata. The two cars are similar in price but complete opposites. The Z4M is way fast with 330 hp and a sub 20 second 0-200 km/h but the clutch is vague and the car is fairly heavy. The S2K is light and would feel more like a miata but lacks on the speed side. Any anecdotes or experience from anyone here? Thanks!

The answer is always Miata.

I test drive an s2k. Nice car, zero low end, weak midrange.
if you like buzzing around at 5+k rpm around town it's a cool roadster. Way overpriced in my opinion.

never drove a z4

You like the nimbleness of the Miata but want more power. Buy Harold Hammerly's car in the sale section and be more nimble than the Miata you already have and faster than the BMW you are considering.

The BMW Z4 weighs 1000 lb more than the Miata. That's four fat girls riding with you in your Miata. Do you expect that to be nimble?

Bit confused on your location. About me says US, but you give quotes on km/h?

BMW is a pig, magazine specs don't match reality.

S2000 is an awesome track car, but for the price you can buy a nice C5 Corvette that will stomp it into the ground on street or track.

Nimble would be shifter cart.

I am US but I like to use Automobile-Catalog the complete Catalog of Cars, car specs database and they list first in km/h

Was it Top Gear that said it wallows like a fat piggy?

I just looked up the quarter mile times on the z4m and it's reported to be about 13.4 seconds. Sonofthehill on this forum is running 12.08 seconds in the quarter mile on a Chinese turbo and a log manifold. That's a bunch of car lengths.

I was catching and passing Corvette C5 ZO6 on the track on the straight at 262 horsepower. Harold's car is making 318 at the wheels and is completely sorted out with beautiful paint, huge brakes, built engine, great Turbo, and a premium suspension for only 15 grand.

This just in: Stock Honda is slower than an aftermarket turbocharged car.

BREAKING NEWS FOR SURE

lol @concealer404

@sixshooter my turbo miata is a cheap setup and not well tuned so I aint putting down a whole lot. When I first finished and drove it turbo I had 1500 in the setup and 2300 in the car. I am just looking for something with some oomph that won't need constant repairs or worry about it exploding and sending a piston for a long overdue flight. I want a long term car I can enjoy without it being the "boring" DD family car.

then you are doing it all wrong and buying/using shit parts on a shit car.

buy a nice/clean 3-4k miata and use proven reliable turbo parts.

I personally have had zero turbo related issues with any of my turbo miatas. Most recent stuff that actually broke are an alternator and a power steering pump. $50 each and an hour to swap and it's all good again.

This is 100% true. The most have had to do to my setup was clutch master and slave cylinder and the rest has been fine. And that was last year all mine has seen all summer is gas oil and tuning time.

well yea it was a shitcar build just to see if I could. Most of the kit is FM with a china turbo and friend made exhaust. Leaks oil like a mofo and recently the exhaust split in half after an exhaust leak before turbo started igniting exhaust. I fixed the exhaust to find out it had done some damage to turbo. I replaced the turbo with one from cxracing since they were made in the US I thought it would be better. The only thing made in US got me is some ancient/proprietary flange that no one can seem to find and cxracing told me the flange can only be gotten as a combo with the turbo so now im sitting with a nonfunctional vehicle that has been that way for 3 damn weeks.

i have a non turbo exhaust that you can put on, hell you can put my turbo kit on.But you need to invest in quality proven parts for a reliable car.

Pick two

• Cheap
• Reliable
• Fast

Lol @cxracing made in usa.

its the same China shit that you see on ebay, comes from same factory with the only consistency cxracing orders the same spec turbos over and over again, unlike Ebay that constantly changes their specs.

of you can afford an s2k. $10k+ price tag, you can buy or build a real sweet dead reliable turbo miata that will blow the doors off any $10k s2000

Ancient/Proprietary flange?

Are you telling us that you're having a problem finding a T25 turbo and downpipe flange?

Having owned a turbo miata or 3.... i'll take an S2k over a $10k total invested turbo miata, thanks. Twice on Sunday.

Its a t25 turbo but not a t25 flange. It's closer to a t3 but even thats off. It seems that standardization in exhaust flanges isn't always perfect.

You should be able to find a 2554r or 2560r for relatively cheap. I think for the price of a s2k, you could be in the k-swap price range for the miata.

I don't get it. FM manifold is based around a T25 turbo. I would suggest you get a T25 turbo.

Goodness its given about as much trouble as you are having understanding. It's some POS turbo exhaust housing that fits the manifold great but wont fit the downpipe I got made for 500 bucks to find out the turbo was broken. The flange leading to downpipe on turbo is a completely different flange from a normal t25. I have sent measurements to vividracing and they were unable to find a flange to fit.
