Hey,

My brother has just put a bigger turbo, bigger injectors and a Z32 AFM on his R33 Gts-t. I think the turbo is GT35 size, not sure of the brand. The car hasn't been tuned and the ecu is a Power FC. He was thinking of driving it around tomorrow.... Im thinking that this would be a super bad idea and can damage the engine? So I was wondering if he could drive it at all? Could he drive it if he didnt hit boost?

Will it be ok to drive around at low revs, or will it Tick Tick BOOM!

Thanks :thumbsup:

As if he's gonna drive it around without hitting boost! And if it isnt tuned for the AFM then he will be lucky to get out of the driveway. But its up to him. It will be a cool story for you to tell us when he blows his engine anyway! look forward to it !

+1 for won't start.

Great choice... GT35 on a stock RB25... Its going to go tick tick boom anyway.

Good luck.

Another guy on here running a GT35 on an unopened motor, 25psi 475rwhp, 3 years. All depends on your driving. As a daily driver it will last.

To OP, as others have said, it won't start with those injectors. AFM you can get it working in the PFC, same as injectors if you know how to set them. It will be driveable to get to a tuner. I drove my car with my Z32 and SS2 turbo to the tuner then had them fit the injectors in.

A while ago I had a tune on my power FC for 200rwkw (stock injectors, stock turbo). A year later I had 740cc injectors put in, along with a high flow turbo. I then tried to drive it un-tuned to the tuners. It was running like crap, black smoke was pouring out, it was spluttering and I couldn't go over 30km, it made it less then 1km before the car completely died. Flooded the engine, had to get a tow..

Not worth it.

    • Hard to say, just pop the rocker covers off and have a look if you think it's cammed. You probably need to replace the valve cover gasket/half moons anyways.
    • From my youth: GTi-R clutch change is a massive pain. The gearboxes are fragile? But the car is super cool and I want one 😢 
    • Remember this is 1988 tech.
    • Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.    
    • heh, aint no R32 ever meeting modern targa cage rules unless the driver is veeeery short OP, good luck with the sale, since its already in the land of freedom I'm sure you will find a good buyer.
