First post here, hope it works for me. I am rebuilding a high-mileage RB20DET in hopes of >350whp, so I need a few parts to be on the safe side. I already ordered head studs and 1.5mm copper headgasket with sealant.

Water pump

Thermostat

Fuel filter

Intake and exhaust manifold gaskets

Where can I source these parts? They are rather hard to come by in the US. Would any other parts be beneficial?

Thanks.

RB20DET....350rwhp? You need to be more descriptive about rebuilding a "high mileage" motor. Add on oil pump, timing belt, big injectors. What is it going in? do you allready have aftermarket fuel pump, FMIC big exhaust and aftermarket ECU

ps welcome to the forum, a good search will bring up heaps of info on what you need

When I say high-mileage, I mean high-mileage, 150000miles. Compression test was fine and everything looked nice once I got the head off.

I have 6 top-feed, high-impedence RX7 550cc injectors, 300ZX TT fuel pump, 300ZX N/A 6-puck race clutch. Stock ECU and uncut wiring harness(i.e. front clip). Bi-intake setup with the stock MAF, this will accomodate the double-sized injectors. FMIC is to be determined as I don't know what model 240 I want to drop the engine into. Turbo will be a T3/T04E 50-trim with internal wastegate. Tubular exhaust manifold Jet-Hot coated. 3" straight exhaust, no muffler.

For fine tuning of the fuel, I will use a little pot. mod, found here.

http://www.autospeed.com/cms/article.html?&A=0008 This will get the car running with moderate boost. A PowerFC, or something similar, will be employed once I crank it up.

Thermostat and fuel filter are probably the same - or at least very similar - to the 300ZX-DET(T), or most other Nissan models. Similarly for water pump - but don't quote me.

The inlet gasket is only normal paper type, I believe you can buy the paper, so make your own. I'm sure there are people in the States who do custom exhaust gaskets.

Possibly not you'd have to ask them. In Aus since the upsurge in Jap imports most of them have woken up and have the factory parts cd. Possibly hasn't happened yet in the US. As pointed out earlier in the thread some of the parts are interchangeable with other Nissan models.....the trick is...finding out which they are.

If you get stuck I'd be willing to see about getting bits for you.

    • Ok I get you. But isn’t the butterfly intake a headache with the +T?  see this is my plan so far but please advise me into the right direction.  Nistune Ecu, 1000cc Bosch injectors, TD05 or TD06 Kinugawa turbo using stock rb25det exhuast manifold, walbro fuel pump unsure of model I think it’s 450/460, spitfire coils and sparks to suit and a R35 MAF sensor and boost sensor.    I was thinking maybe do a cheap eBay plenum $400-500 or try find a stock det neo intake. I think I’d port match it so it’s getting the full capacity but open to advice please.  Thanks 
    • The issue now is the 'fuel cut' while driving, and when it happend, it does not stall. This, I did not test the fuel pressure while driving as I cannot with a fuel pressure gauge. I do have Nistune logs, yes. I have also replaced the MAF Sensor.   Also related to the FPG Fuel Hanger – I just realized that I need a Deutsch Crimp Tool to crimp some cables for the FPG Fuel Hanger. Need to purchase additional cables as the kit only included 2, which are for the float. FPG has not responded to my emails so far since purchasing. I thought about taking it to someone and having it done professionally, but I am reluctant since everyone I took it to messed up in some way.  
    • There's a good German place in Brisbane if youre up for the drive 😛
    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
