HR 30 problems

[machg]

Guys, a few questions for the learned:

1/. Turbo slowly gets noisier and noisier, then all of a sudden HEAPS of oil smoke out exhaust......stuffed turbo oil seals, right?

2/. A good (and cheap) water cooled turbo upgrade for an L20ET, I'd get a ??? of a ??? (more interested in reliability than performance upgrade)

3/. How hard is it to get the turbo off an L20ET?

4/. L20ET + L28D crank and ??? rods/(standard pistons?) = L??ET (how many cc's and how hard to do)

5/. Does anyone have a central locking motor from an R30? - Long story, you don't won't to know.

Not urgent, car off road for 5 months, but any responses would be appreciated.

ok for starters you have a dead turbo there, a replacement turbo would be something like a ball bearing rb20, your turbo on the l20et should be oil feed as theres a oil line running from the oil sump to the turbo, i had a bitch of a time trying to get the turbo and manifold off my old l20, ended up just getting it all taken away?? i think each door has its own motor in the r30, a wrecker with a MR or HR should be able to get a motor for you, i've got a centre control unit waiting to get the motors for the hr30...

1. More than oil seal me thinks!

2. I'm sure the L20's had T3's stock,so I'd go a T3 style turbo....maybe an RB25 BB (R33 Skyline) ,or an older stlye water cooler T3...

3. How handy are you with the spanners? It's not real hard...

4.???? Ghostrider would be the man for that one

5. As RSX said....or buy a Jaycar central locking kit for $40 and use a solinoid from that.

Gonna have a crack at pulling the turbo this pm. Have fitted a Jaycar central locking kit, but doesn't work on drivers door due to lack of locking motor, hence the search for another. (None in any local wrecking yards.)

Thanks for feedback guys,

RB20DET turbo bolts straight up. Need to manufacture the water lines though.

Actually, I've got one here, off a red-top RB20DET, that you can have for about $50. Needs a wastegate actuator, though.

Forgive me for this....but what the hell is a "locking motor"???????

:confused:

:confused:

if you have central locking theres little motors that pull down the locks?? when you push down the main door lock....

[0HR-30T]

Ahhhhh Now I see.Otherwise known as solinoids If you (machg) buy the Jaycar kit I'm talking about,then it comes with new solinoids.Either a 2 door or 4 door kit--has 2 or 4 solinoids,and can be hooked up to your existing system....

[rsx84]

those jaycar kits are $29.99 for the 2door or $39.99 for the 4door wire them up yourself..

[0HR-30T]

Too easy!

[machg]

Yeah, originally after discussing the problem (driver's door lock stuffed) with the guys at Jaycar, they sold me a "remote locking/alarm" kit, which (unfortunately) didn't come with any solenoids, I guess Jaycar might sell me a spare solenoid (considering the kit they sold me doesn't work to my satisfaction). Geez I reckon changing turbos on the last model 300ZX would have to be easier than changing the turbo on an L20ET; what an absolute BITCH of a set-up.

L20ET update: Its Not Impossible! Managed to finally get turbo off engine. For those interested; this is how I did it. 1/. remove all attachments to intake manifold that prevent access to retaining bolts. 2/. Remove all shit you can from around exhaust manifold and turbo and undo exhaust system at end of dump pipe. 3/. Undo and remove all manifold retaining bolts. 4/. Remove intake manifold, remove exhaust manifold. Getting turbo off exhaust manifold is a piece of piss once removed from engine bay. Four 17mm retaining nuts with captive washers (bend away with small screwdriver)

Sounds easy? Its NOT! To get the bolts holding manifolds on underneath them you need small, a good quality 12mm socket, long extension (at least 15cm long), universal joint and ratchet. (Sydechrome - thanks Dad!) and smallish hands (I could JUST squeeze one hand in to feel location of bolt heads).

Door locking motor: Jaycar does one for $10, will fit today.

Thanks for feedback guys, I hope someone finds this interesting/useful.

i didn't get my manifold off! and my engine was out of the car at the time, even hoisted the whole engine gearbox up by the turbo manifold and it didn't move, used a penitrating oil nothing. its on there for good now!

Push down the main door lock???????

What's this that you do???? My central locking works when I push the button of the remote!

Anyways, doesn't the stock MR30 Ti central locking work off the key?????

4/. That's right, I probly be the man for this. Don't waste your time with the L20A engine block, it might be the same physical size as any other L series 6 cylinder, but you cant put a 10.0 mm over bore down it, the cylinders get a bit airy!

If your going to do the stroker deal, you need a bigger block and not ZED blocks as their sumps and oil pick ups are all in the wrong place for R30's, and the LD28 crank is only comp[atible with another L28 block without a fair amount of machining.

Do lots of homework on the subject before you embark on it, as it is super expensive and more so if you **** it up. It is not the sort of engine build you can do and cut corners, it's either all or nothing and then it has to be THE VERY BEST of ALL, not what you can afford.

I have got all the bits, but i'm not going ahead with the build until another day, the easiest way is build a stock L24E into a turbo using maybe the L26 crank and find some pistons, the L20ET manifolds all bolt on.

A TURBO! An T03 off an FJ20DET is identical in every way to the L20ET turbo with one very important change, the turbine housing is nearly twice the size, from .46 to .87 A/R which should make it spool up faster and produce more power. The FJ T03 mounts to the stock manifold, just like the old one (L20ET)

Thanks Ghostrider, sounds like the easiest power upgrade is to wind up the boost a little! Going with that turbo off the RB20DET (cheers BlindElk) be back on the road early 2005.

Unless your going all the way to 3090cc, the stroker isn't really the go and to have a strong 3090, the F54 280ZX Turbo block should be used, in conjuction with a P90 head.

At the end of the day, some extra boost is the answer in a lot of cases.

Hey there Ghostrider, how goes the Newman & RMR?

The L24 will rev harder, but the L28 will pull stronger. My L28ET 240Z will make 15psi at 2000rpm. The stock NA compression is influencing that but it pulls like a truck.

It is not too hard to produce 400HP+ out of a mildly prepped L6. My under-construction TT F54/P90 engine is aiming for 450HP, but SKY-084 here in SA has over 180kW at the wheels with an LPG-only L'27' setup (including locked dizzy).

i've also been told that the turbo off a VG30 (single) will bolt up as well and being a newer model should work as good if not better than the FJ, but remember it's off a 3lt, maybe use the L24 block(for under 2500cc comp events) and might work ok! also what intercooler should be used in a r30? not much room and not wanting to cut up front bar(orig HR30,diffrnt to local)

put up extra photos of enginebay pls look!

[machg]

You can fit an R33 GTS-T (yeah, I know its puny) cooler in front of the radiator, but I had to cut a little out of the top of the grille (not visible from front) and use a tight bend (see a turbo specialist) at bottom cooler outlet.

cheers,

with the iron mask front, ive got the hybrid 600mm x300mm x70mm fitted low...
