Hi Everyone. I am wanting my 300zx tt to safely produce 300 - 350 rwkw preferrably on e85. The engine is currently undergoing a full rebuild with forged parts. To get to this figure i was thinking of aftermarket turbos but not sure what type, 740cc injectors, upgraded fuel pump, dump pipes & test pipes full exhaust, SMIC and aftermarket ECU i was thinking probably Haltech. Is there anything i am missing that i would need to safely produce this power as i dont want to push the new engine to its absoulute limits and also how much boost could i run before things start to fail. Thanks
Heads being ported, Larger valves, bigger camshafts, BDE camgears. Exhaust headers , 2860 turbos. EBC if your chosen ECU doesn't do it. Radiator, clutch, brakes, the list goes on and on.
You will not make that power on e85 with 740 injectors. They’re just not big enough. High flowed stock turbos, adjustable actuators and top feeds will do it. Stock cams and valves and you have a bet responsive motor. Yes have done it before.
^rob is on the money- Cheapest option 2560’s or hi flow turbos Actuators if applicable 1200cc side feeds (not personally advisable but saves going top feed rail) Walbro 485 Least a full 2.50” exhaust Larger intercooler (front or sides) Nistune ecu EBC The bottom end should be strong - assuming your doing ARP main and head studs in which case it should make 300-350 relatively safe
im currently sitting @ 304 rwkw on 17 psi shell ron 98 with high flowed auto turbos 3 inch split dumps to 2 1/2 system manual tt cams 550cc injectors @ 80% turbosmart fpr walbro 460 fuel pump big side mounts with standard IC piping link g4 ecu low km engine completely stock
Rubbish! I'm making that on 650's at 86% peak duty cycle. This is another one of those marketing furbies that has been getting around for far too long.
All you need is a dead stock engine (all the standard deletes), EBC, Nistune, high flowed turbos, bigger smic's, bigger injectors (650's will get you to 350rwkw at 19psi boost), and a decent heavy duty clutch.
Edit: also factory fuel pump and fuel system is more than capable, just add an aftermarket FPR. And decent dumps and exhaust.
Thanks for the input everyone, either way it seems pretty easy to make decent power out of these cars
Haha, the true test of performance is on the race track. If you want to talk measuring dicks Rob, when was the last time you tracked yours
The last time it went around a racetrack was the Oran Park short circuit. That should tell you enough!
And just to take all the 'dick measuring' out of the equation lol. I recorded 355rwkw at just over 19psi on E85 on yes a hub dyno. So assuming that this is likely to read less on a roller dyno, do you really think it's going to read less than 300rwkw? The OP asked about 300-350rwkw. 740's will handle this easily. Also for what it's worth, if you understand the variances in roller dynos and all the different Shootout modes and how they work, you'll understand that roller dynos are arguably the most inaccurate of all dynos. All you have to do to change the output is change mode or even just change to a different tyre. Not saying hub dyno's are necessarily more accurate as it still comes down to the calibration factor entered, but they do remove a lot of the variances that you find in roller dynos. Dyno's are only good for tuning and for comparison on same dyno on same settings on same day.
I honestly don’t remember -took it out on a lotus club day with my old man, I do remember he managed better than I did...
In terms of providing accurate feedback to the operator a hub dyno is much better... but the reason it’s a better tool is also the reason they give a higher HP reading than running the same car on a roller dyno. Re injector sizing don’t take my word for it; check out any one of readily available calculators. Have put Nismo 740s in a car with standard turbos and e85 in a car before and it certainly didn’t make 300rwkw. It made more than it would have on 98 but from memory ran out of fuel around 280rwkw. Numbers could be off a little as not my car and I didn’t tune it but key point being ran out of fuel before ran out of boost. Compared to putting 1000cc top feeds in a few cars now with standard turbos and they tend to run out of turbo around 300rwkw with plenty of fuel to spare.
