Don't think so, not without extensive modifications.

And a shed load of turbo lag for the 5mins that they would last for that price. No point in buying cheap and nasty parts if you want it all to last.

If you buy the best at least you're going to have a good chance that the turbo wont disintegrate and get ingested by the engine.......however........some people (Noz is one of them)have had great success with cheap chinese turbos.

If your going to buy Chinese turbos, there were godspeed 300zx kits for about £350 last week, almost cheap enough to take a punt. But it's a risk, not just to the turbos but to the engine, imagine if a turbine shattered and was Ingested by the engine, that's a rebuild ££££.

No offence buddy but you seem to just be going round and round in circles. Why not just make a choice based upon the advice you've been given and stick with it? It's a street car at the end of the day so anything above 500bhp is virtually pointless, which can be achieved on not massive turbos.

A set of gt600s and some 555s with a good map and you will be making enough power to melt your tyres in most gears and have to refocus yourself on how to get it on the floor. You will be putting down more bhp per tonne than a f430 without the wizardry to keep in all in check.

Indeed, the first ones from about 9 years ago. XSPower T70 (comparable to a Garrett T61) on a 1.8L at 1.7bar and 382bhp@hubs. I bought one of my Pulsars with a Chinese GT2871 and ran that up to 2bar. The car was simply out of this world with great response. You could hold it at 130mph on part throttle, then floor it and it would push you back in the seat as if you were doing 80!

 

I'm currently running twin Churbos at 1.7bar on my Zed. No air filters, just mesh over the inlets (not ideal for reasons other than filtration considerations). These were randomly selected and picked up from Toyosports on the way down to Jimmer's before TOTB when it became obvious that my T04Es would never be fitted in time :wack: They are performing perfectly for cheap journal turbos.

 

I mapped Phutumsch's Zed to 590ish bhp with GSP600s. They were smoking a bit, but that could have been sorted prior to fitment in the same way as with a pair of £2k Garrett ball bearing turbos.

Whatever you do Spin Doctor, do NOT spend £2k+ on a pair of Garrett GTX turbos. Massive waste of time unless you're prepared to run 2 bar minimum and have the set up in place for that boost level. With regards to the turbo in that link, you'd only need one of them with a single turbo set up.

 

The main issue with using Churbos on a Zed is labour if they do go wrong. But that's part & parcel of Zed ownership. Garrett GT28RS turbos have a chequered history when it comes to reliability.

Totally correct Noel bud, i didn't have the ball bearing oil line restrictors fitted so at this moment in time i am thinking the smoke issue was this.

 

I am going forged in the new year and the turbos will be examined, not saying the seals or bearings are shot but they will be replaced as a matter of course, it could be however that this is not necessary.

I was very close the other day to sealing a deal with some gt28rs tubs but the man didnt want to let go of his dps etc.of whitch is aceptable. That said im more than pretty set on the idea that Mark darbeys going to do.hill have to explane.to tech for me. I dont want to get info wrong.just waiting on some results to come back in .in the new year. Happy days. Then full speed ahead

.cheers for all advice though. Thanks.

Once I have set up & mapped the first car fully.

 

The car has been mapped to actuator pressure (0.5 bar). The turbos have better response than stock items, I was seeing the ECU access parts of the map I haven't had to work with before on a 300zx (very low RPM, high load). Impressive so far.

Interesting stuff, I'm assuming there are breather mods to compliment these. I hate turbo lag.

Which turbos do you mean?

The ones he's been arranging with mark, the ones that you say have a better response than stock.

Whats the factory setting for the acuator.on a zed that rolled of the production line.

Ah, it's just you mentioned lag, and that's not really an issue with the VG30DETT until you get to GT30xx or bigger on a stock engine. If you've ever owned/driven a Cosworth back in the day, that is real lag (well, high boost threshold to be precise).

 

These turbos are the opposite, more responsive than stock which is a first. There is more R&D to be done though.

Stock Nissan actuator is ~0.5 bar.

Yeah it's not too bad, obviously there's some, it's not like an NA. It's been a consideration in terms of what to choose as I don't want all the power from 5k onwards, stock is acceptable. As it is/was it's pretty good, however I don't want to fit something that ruins it's drivability.

Please tell me you guys are working on a twin scroll setup!?!

"Lag" really isn't a concern with the Zed for an 8.5:1 compression ratio engine with twin turbos, you can't compare them with N/A cars fairly. I was able to make 480lb·ft (fly) at just 3800rpm on the standard auto turbos. Standard Zeds hit 283lb·ft at 3600rpm. Even Jaffa with GT3071Rs made 634lb·ft (hubs) at just 4700rpm, albeit with lots of PowerZed wizardry helping. Even with the old-school GT2870 Churbos on mine, it pulls cleanly from 1500rpm in 5th. My Impreza WRX PPP would literally kangaroo itself to death. The Zed definitely does not fit my definition of lag :wack:

 

An good spec for a very responsive but powerful setup with a stock unopened engine would use free-float billet T28-size turbos run at 2.5 bar peak with dual 50mm external wastegates (20psi springs). Blow-through MAF, 2.5" pipework, engine-bay front mount (would need to downgrade to electric fans, unfortunately), AAC valve set to 15%, 3" downpipes & fully divorced 3" exhaust system, custom engine mounts for straight intakes to the compressor housings.

Afraid not at the moment.

Cheers for that Noel, I'm not sure I quite explained myself properly but you gave enough information for me to get what I required. I should be on spec.
