RB20DET OEM replacement parts

[wcbjr]

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.

And searching usually only comes up with what parts I need, not where to get them. People magically leave that information out of their posts. Happens all the time in my Subaru forums.

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.

Any Nissan dealer should be able to supply OEM parts failing that nengun has a good reputation on these forums

Thanks for the link.

Even stateside dealers can get RB parts?

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.

Thanks for the offer, I may need the help in the future.
