In short, YES. You don't have to replace the pistons with forged items. You definitely don't have to replace the rods, they are already forged. With a healthy engine, forged items are a choice and not a requirement at that power level in a road car. A track car would benefit from forged pistons to better withstand the in-cylinder heat & pressure for prolonged periods. Lighter aftermarket rods have benefits in such a scenario too.

Rods & crank are forged from the factory. The stock pistons are cast, but still strong and can cope with 600+

At £1.30 per litre, 45 miles from £20 is 13.3mpg. There was a problem :wack: I managed about 16mpg last night, 90% 'spirited' driving :shifty:

No, they are brand new. Guess where they originate from. Trust me, I have done the research.

They're brand new injectors. 6 for £144. What could they be....?

They are the OEM speaker connectors, the original speakers had individual amplifiers.

The fuel pump control unit? It doesn't have any maps programmed into it. Do you mean the TT fuel pump control unit? You're not running a stock NA ECU are you?

You might want to check the cost of genuine JECS injectors first of all...

Hello & welcome :) Use Photobucket :)

Hello & welcome :)

Thanks everyone, had way too many :pint:

Coolant temp = water temp. Temp sensor for the gauge is the single prong sensor, don't touch the other one, it's used by the ECU. Buy a sensor for your alloy adaptor.

400bhp & 400+lb·ft is nice & easy on stock 370cc injectors & TB022 turbos. The key to these engines is allowing them to breathe as they are so restricted in standard form. Full exhaust system (divorced turbo elbows, decats, cat back, all 2.5" diameter) Air filter(s) Uprated side mount intercoolers or FMIC Boost controller1 NGK BKR7E or BKR7EIX spark plugs2 Nistune ECU Also worth considering: Uprated fuel pump (320lph) Dual intakes 2.5" intercooler pipework JECS/NISMO 555cc injectors 1Boost required will depend on the BSFC of the engine (ie how much power it makes for the amount of fuel used). This depends on how efficient the intake & exhaust setups are. 2If you would rather use higher boost levels with less modifications to achieve the power, I would recommend using BCR8ES spark plugs. This will of course increase wear on the turbos, replacement of which typically requires removal of the engine. The 300zx turbos are TB022 (hybrid T25/T2 units unique to the 300zx) with an A/R 0.63 turbine housing on the manual cars. Boost will drop off in a depressing fashion on a standard set up when increased over standard. You can achieve large torque figures without troubling the fuel system due to this type of boost response and intake design (see my sig for an example). The small turbos simply cannot push the required airflow at higher RPMs. 400bhp & 410-420lb·ft is a common set of figures I've found. The VG is over-square in design (87mm bore vs 83mm stroke), but you don't want to push the revs much higher than the stock 6800rpm. There's no real need to as there isn't a great deal up there to be had unless you've got much larger turbos, uprated valve springs and minimal intake/exhaust restrictions. It's not a lazy engine, but it's no screamer either. I typically set RPM limit to 7000. My car with stock turbos at 1.7 bar, 481lb·ft @ 3800rpm & rapidly-failing autobox would leave pretty much anything standing (traction allowing) from 40mph - 120mph once the pedal was buried. I miss the response, it was truly rapid and could maintain 140mph at part throttle with ease. Digressing slightly, one thing I have seen over time are big power Zed builds that quite often seem to run into trouble. I've been around cars for some time, built engines, swapped gearboxes, clutches, bodywork and all the rest, but I refuse to attempt everything on the Zed myself. Jimmer @ PowerZed fitted my latest turbos, clutch, manual conversion, 850cc injectors in a single mad week before TOTB. I wouldn't have my custom intercooler without Steve @ Silverline Racing (no longer trading unfortunately). I have some admiration for those that do attempt everything themselves at home, personally I'm way too fickle to have a car in pieces in the garage rather than on the road, it would get broken for parts in no time (like my old more-door R32 GTR). But it's also puzzling to see, as the standard engine and car in general have so much potential with the stock components. There's a Zed on here that ran around 700bhp on a bone-stock bottom end for final two rounds of Time Attack last season.... Anyway, hope some of that helps :D

All the best :pint:

Hello & welcome. You've had some nice cars according to your PhotoBucket! P.S. Your offside alloy is on the wrong side :D

No need to guess with any sensors, Consult will tell you everything you need to know. £15 for a cable, free diagnostic software. Even buying a laptop for £80 it will pay for itself the first time you hook it up if you value your free time and sanity :D

Whenever an engine ingests oil, it will produce blue smoke. If it only happens at start-up, and is visibly worse the longer it has been stood, it could well be the valve stem oil seals. Have a look in the plenum via the balance bar ports, see if there is a lot of oil in there. If so, remove the PCV system from the equation to test. Did the old turbos fail? Are the intercooler pipes full of oil? Just something to check for, won't have any bearing on smoking from just the passenger side. Are you sure it doesn't smoke under boost? Worn piston rings result in smoking all the time and the engine will breathe heavily through the dipstick, oil filler cap & breather system.

What was wrong with it?

What I know about bodywork can be sprayed on the back of a matchbox I'm afraid :wack:

Just use your laptop & Consult :)

Chinese turbos can be good. They can also be bad. It's a lottery, but one I play gladly when it comes to my own car :D

If there's air, fuel & spark, the only other things you need are compression and correct timing of the spark.

That's the type I always find floating around a Zed engine bay.

He wasn't overloaded with tech speak. Every acronym was explained (CAS, DTC etc) and I even supplied a picture of an engine. My posts later were tongue in cheek, at the end of the day, until DTCs are relayed on here, it's all a bit moot.

It would be incredible :)
