Finally , all the parts are here and the workshop is ready !

I had a 3/4 mongrel when my Skyline went in for the works - But this is different.

Learning from the past builds, parts, bits, pieces and workshops has taught me a lot.

Can't say that I have it 100% perfect this time - but has to be better than the last try !

So now I have a 7/9 mongrel :D

I'm pretty excited -

3-4 weeks I should have it back.

Not going to speculate about peak and average power, but I am hoping for some good numbers ! And then some good times to back it up.

Geez, I havent been to WSID for ages - Can't wait for a test run !

It's going in to Race Solutions / HitMan for the works - Maroun from RS will do all the mechanical work and fabrication - and Matt will do the Haltech install and tune !

Cheers !

Need help urgently .....

The 1.00 AR rear housing on the HKS T04Z is too small...

I need a 1.15 or 1.32 housing from Garrett.

If anyone wants to swap outright or I can buy outright - let me know !

Cheers,

Nothing on the internals yet.

But when I do it won't be dramatic. SCR Seals. Maybe a mild extended port.

The motor is pretty fresh - and the 20B flows heaps enought to spin the turb. So I'll just leave it for now until - (a) something breaks and ((B) fundage is a bit better.

PS - 2Rismo ! I have been convinced to trick the auto. I'm sure you'll be happy about that. Cosmo's share gearboxes with Nissans ! ha ha - Same as a 300ZX. I'v e been put in touch with a place that can work magic on these things.

Something will break eventually with a T04 on a stocko 20B :yes:

Get some nice big porting and some tougher seals put in, and some extra dowelling and up the booooooost :(

P.S. Autos are for poofs :laugh:

Good man! I'm guessing BMS/Wollongong Autos or Powershift. The box should be an RE403A yeah?

Not sure on the details mate - but Maroun from Race Solutions has a mate that has done many 300ZX boxes - I think he said that they are Jatco ??? No sure but.

Apparently he can set them up for the best of both worlds - Full manualised auto with steering wheel shift buttons , fast changes - And then flick a switch and can go back to the feel of std auto.

2800 or 3000 RPM stall converter means that I will have boost straight off the line. Therefor more average power to the ground than any manual. This offsets by far any drivetrain losses of the auto.

I still don't quite understand how it all works in terms of the stally slipping etc - but I wil ldo some more research - As I don't like putting things in my car that I don't understand how they work - ha ha.

Should be a beast with the 1.32 - Now looking at 400kw at the wheels - then more if engine re done and max the boost.

fingers crossed - no b-manning !

Ye of little faith Drunkan !

300ZX Autos are RE403A's i'm pretty sure. Some interchangable parts with Skyline and WRX boxes (RE401A) but overall a bit bigger and stronger.

Nice that you can still use the steering wheel for shifts - B-Man + 400kW launch = OMG!!! :P

I can speak very highly of SCR seals too! Webby does a great job on them and I've seen them take a huge battering. Cheap too!

Jumbo - had a big think about it - and I will have the TX3 turbo project for the manual fun ! So sticking with the auto onthe Cozzy now !

Fair call.

      Blue/grey smoke after idle

      By Duncan · Posted

      I don't know, I've never done it that way, but 1. While it is an interference engine, there is still clearance between the valves and the piston at all points in the regular timing cycle 2. There is not a lot of distance before you can't catch the top of the valve stem any more I don't know if 2 is greater or less than 1. But 3. If it doesn't work out you are f**ked, engine is coming out to disassemble so it is a big bet.

      Semi slicks are horrible for road use, just use a high performance road tyre unless you really need the maximum grip. Noisy, unpredictable (amazing, until they are not), expensive due to very high wear and not good in cold and particular wet. And yes, it is a thing to store cars on stands instead of tyres if you know they are going to be parked up long term.....but who ever realises that a short park is going to stretch into years before it is out again!

      I know in Australia you'll definitely get above 30c. Parked in the shade in Summer you'll be above that. 😛 But in cooler climates, you might get that warm driving on the highway for a bit, but you'd never get to full heat temp. I'll try and find some of my historical tyre temps between Aus summer and winter (be aware immin the warmer area of Aus too.)

      I get that taking off the head is best but that's a bit much for "just" valve seals. I was just under the impression that one would be able to rotate to TDC and be able to temporarily drop the valve without losing it and effectively having to remove the head to then recover it. I never knew people actually pushed rope into the cylinder to do valve seals hahaha So just to confirm, just going to TDC will not work? In that case I know when I do valve seals I'll maybe just remove the head and do some other things while I'm there, or just wait until I do an engine build.
