So, the Black street car is going on the dyno on Friday, and will probably be there for the majority of next week. My tuner is a 1 man show and can take a while to get it done. That said he does a dam fine job and I don't mind.

The Yellow race car is ready to get started on. It is getting a new motor, box diff and suspension. The motor is well underway, a 26/30. The head has been ported, 1mm oversize valves, up spec springs, short skirt buckets and HKS type 2 cams with old school HKS cam gears. I have 3 blocks and cranks to choose from. All 3 blocks will be getting basic preparation, acid bath, bore, hone, deck and bore squirter seats n holes machined. I will be Grout filling the block to the welsh plugs to help control the warp that is common with these things. They tend to split down the welsh plug line under load, about the 650-700bhp mark. Guess where I'm aiming for?

The crank is a std RB30 item. We are looking at doing some offset grinding. Knife edging, enlarged galleries, grub-screws, match grinding and balancing. I think Spool rods with ACL race series positions and bearings will be next on the shopping list. Stay tuned for pics. Might be a week or so.

Sounds like you are getting serious with it now.

Good stuff :thumbsup:

The new engine build sounds wild Noddy!

That hoist would help a shit load! Im super jealous.

I can give you a few ideas with the sump if you like... What sort of pump you looking at?

240V or 415V?

got all the required locks etc on them to stop them dropping? been looking around a bit and that price is pretty good for a new unit for 4.5t

Yes they have Chris, Dan has one as his second hoist in the workshop and they are the real deal.

Michael, I'm surprised you don't have a hoist. Will pm about pump/oil setup. I have been tooking at Cammo Hill's setup.

Chris, yes it has drop locks and arm locks that disengage when it comes down. It is 240V 10A single phase. we have used the hoist heaps already this week. Skyline, Falcon and ceilca have all had a ride or two.

I have been trying to tune the Skyline for the last couple of weeks. First issue was that the 9 pin serial cable had been damaged and need a new 1. that took a while, turns out it is not a normal straight through cable, it's a 232 null modem cable. same as an AIM dash.

A new cable in and it was just a matter of gettin on th dyno. There has been a bizarre boost issue, apart from it tailing off it would flutter around 4500 up making tuning hard. We use a live trace to identify exactly where to make changes....... it was all over th place. We data logged a ramp and found the boost pulsating from 14.8 down to the 9's and back again several times a sec. We changed map positions on the plenum a few times, even tried a different EMS ecu! went back to the original spot and it was fine????

So with the flutter mysteriously clearing up, the boost drop was still a serious issue. 14psi dropping to 8.5, why? Boost controller? By elliminating it and just running waste gate psi? still dropped 10 to 7.8 psi. Ran a ramp with a reading at the turbo\wastegate, 12psi, climbing slightly to 12.5 psi. Was there a rag left in a pipe? Short answer, no. We did just run a pipe in place of the intercooler, 11.5 psi in the plenum.

Now there is a new intercooler in and goes back to the dyno, again, tomorrow.

A hoist is something that has been argued about many times...if only we did have one!

I like how you guys go eliminating problems step by step. No guessing or mucking around.

Hopefully you get it all sorted out.

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
