Poor Rb20det, Finaly Being Put Back Together...

[carl h]

ok first of all a BIG thanks goes out to greg at proengines and the rest of the guys there, greg was kind enough (and willing!) to help me source out parts for my rebuild since bits like bearings and timing cogs arent available here stateside, so again a GIGANITIC hooray for greg!

internal mods:

full arp bottom end (rods, mains, and head studs)

proengines crank collar

new nissan n1 oil pump

cp pistons (20thou over, .5mm iirc)

prepped stock rods

nsk bearings (mains and rods)

dual tomei oil restrictors (sorry SK, i'd rather err on the side of saftey when it comes to hydrolifters)

top end:

tomei cams

new nissan oem lifters (i cried when i paid for these)

tomei valve springs

external drains fitted to head

still putting the motor together but its finaly comming together.

only thing im not sure bout right now is the fittings in the head for the oil drain, not sure if the brass bits are up to the job or if i need something else.

thoughts on said fittings are welcome, oil pan isnt sealed right now so i can figure out where to place the return lines...

He is building an RB20 of extraodinary magintude!!!!!!!!!!

Will we see 300rwkws out of it? You were makign great power before so now that it will hold together...it looks to be a great engine

That motor would put a horn on a Jelly fish!

Nice... good to see a bit of headwork - valve deshrouding.

The redbull can really put the piston size in perspective. lol

Maybe you mentioned some where but why and or how did the old motor fail?

[GTR1993]

chances are that those brass fitings with sutable rubber hose will be 100% fine but i prefer to use braided hose for stuff like that, just makes me sleep at night.

(i have used rubber hose in oil cooler applications that are that hot and pressurized with no problems so you will still be fine, but i still like braided even as its astronomical price)

Looks good, now ditch that bloody air regulator valve which is uglying up the very nice looking intake manifold

Why the swap to an rb25 ignitor?

[sproosy]

This is what wet dreams are made of!

[dbo]

hot!!

[fr0st]

Nice build up

Out of curiousity, why didn't you go the RB24 rout? (if you have stroked it... my bad)

[R31 POWER]

Sweet as! What are the 2 brass fittings in the back of the head for?

[rice_me_up]

much respect to you.

even though the rb25 has the upper hand and is an obviously easy engine swap to produce more power, im glad to see someone putting some serious effort into an rb20.

cheers. james.

hehe make the bitch rev to 10,000rpm

thanks for the kind replys guys, its taken me a while to collect all the misc bits i needed to rebuilt the motor.

cubes: motor failed (which i speculate) was due to the previous owner in japan not knowing how to tune a car took the std ecu, chipped it and slapped 30* advance all over the timing map. accelerated ring wear and caused ring land eroding detonation...then you have me doubling the stock power out put and well, old girl wasnt too happy.

gtr1993: word. i'll change them out for steel bits anyways, last thing i want to do is remove a broken fitting from the head with the motor in the car.

BHDave: the ignitior is actualy part of a new nissan z32 retrofit kit, my ignitior had taken a shit and since rb20 parts dont grow on trees here had to get creative, some repinning and the z32 one works a treat; plus it looks loads better than the std piece .

fr0st: didnt go rb24 for a number of reasons formost being cost for the rewards, i couldnt justify the money spent on the power the motor would make. motor was making 288rwkw sooo with a fresh bottom end it can do more for sure. would have loved to do a rb24 but when you factor in parts cost and the machine work to mod the head and what not, simply not worth it as SK said long ago.

r31 power: brass fittings are for the external oil drain for the head, trying to keep oil pooling to a minimum with the use of restrictors and the external drains.

i'll have more pics soon enough, any luck i'll be able to mount the oil pan and then the exhaust mani and turbo...then its just a matter of getting the motor back into the car and breaking it in.

[carl h]

few new pics for you guys...

[Roy]

That final pic makes me anxious...in the next few months the thing hanging off mine will look remarkably similar

[yogi000]

you gaylords with your external gated rb20's

pure evil

cant wait to see

LOL...but how can you say no to this
