Robs Sil80-more skyline than S chassis


Recommended Posts

  • 3 weeks later...

Well spent a bit of time this week going over the 180sx in preparation for hill climb tomorrow. Compression test came back 115-120 across all 4, the blow by had filled half the compressor housing and Intercooler with oil so pulled it apart gave it all a good clean.

Dropped the oil and there was no shiney bits so fresh 20-60 oil went in with a new filter. Still blew a little bit of smoke on quick test drive so see how it goes tomorrow and may give it a bit more boost. 

Hopefully holds together for a few runs.

Cold and dry? 

warm. 


Ended up 5th outright with a 1.01:89 at the hill climb but only did 3 runs as blow by got worse. Thats a new pb too so will be alot quicker with a healthy motor
It was blowing oil up the boost solenoid ref line and out the port.
Tried venting catch can to atmosphere which helped a little bit but still pushing oil to catch can. On the last run turned it up to 22psi but blew off intercooler pipe on gear shift after launch so called it a day.
Pulling engine this week as couldn't find another one locally.

The only way a vent will help is if you vent the sump and the head separately like I did on mine. 

You need to equalise the pressure top and bottom. 

 

Will be doing whole new catch can/breather setup when I get this motor freshened up. Atp 2l can and all dash 10 lines.

Priced up everything for forged bottom end through golebeys so once engine is out and everything measured up will place the order.

Even with a fresh motor, Nissans need bulk breathing capability. 

Vent it top and bottom and happy days.

 

2x - 10 off the top, 1x - 10off the sump and the factory block fitting should be hopefully help. Never had issues with the s14 but the rocker cover is a better design.

Progress back moving under its own power.

Been spending a little bit of time sorting out the power steering setup since I didn't end up going electric. Went with an aeroflow tank as I stuffed up the original one trying to weld on dash fittings. 

Cut off the old bracket and made a template, copy to aluminium, cut/drilled and folded.

Finished making lines and filled with fluid only to find I had hoses the wrong way on the rack. Switched them around, Bled it up and everything thing was all good. 

Also fixed cooling set up by moving one of the fans, got a new nismo thermostat just incase as the old one was around 11 years old. New coolant with demineralised water and now temps around 80c at idle.

Still sorting idle with ethrottle as when I stab the throttle it doesn't return to idle smoothly or stalls so will keep adjusting the proportion and stall gain to make it right. List of things needed to get back on the road is getting smaller.

That won’t be helped by adjusting the throttle pid settings, it will be your base throttle table referenced before closed loop takes over.

Just spent a bit of time this morning doing a few small things like fitting indicators, rear speaks, shortening intake pipe and cooling plates.

Thanks to @Ben C34 advice went back and checked the ethrottle setup and set it up properly so idle is smooth at 800rpm and doesn't stall ?

Big ticket items left is driver side lca, cat back exhaust and Coilovers.
