Well fast forward to now and I am building a new engine for it. Reason being oil in the coolant. On teardown I found cracks in the deck (marked in green). The oil was seeping pass the cracks at t

Look forward to the next installment.

Catch can, this is one thing Im looking into at the moment.

Im interested in the Racepace units as seen on Tangomatt's 34 - going to chase up prices.

Is that the combined washer/catchcan? if so sounds good!

Got brakes back from being machined, on a lathe this time and they are better for street now, smooth, but high speed stop or heat in them still makes em shake a bit, so new rotors will be on the list I think. one is looking like it's had a better life.

Just took the car for a drive and it's been great!

Getrag 6speed is noisier at idle and taking off but thats due to the flywheel, no more dual mass.

The 2860-9's are what I'd thought they'd be like :yes: . Great response, meaty mid range and revs out nicely. It's running at 17psi, 1.2BAR on gauge is maxed out lol, injectors are at 90% and knock has a peak of 22, yet to be tuned but runs great.

In 6th gear I see 0.8bar, 12 PSI at 3000RPM. The way it comes on boost is impressive considering the stock cams, manifolds etc. The engine had cam gears already fitted so I haven't touched them.

Pulling out of corners, it just accelerates, so no real problem being in a higher gear too. :)

Let us know how much they are nick :banana:

Fitted up the alpine x types in the front door today, and bitumen deadener, then it rained so I still have to do the passenger side.

That's not my fully sik scubie by the way! :ermm:

Not much money now lol. Lot of it is doing it smart and not throwing money at it without having a plan/goal first. Made that mistake with the 32, spent way too much.

Will post up some pics soon, go away rain!

Thanks Brad and Scott :blink: White is a pain to keep clean!

Audio is pretty much done, still have boot space. Also sorted out the catch can setup. Put a vent/drain into the dipstick hole from the catch can, seems to work well.

May go an alpine sub and mono block later on. A 4x100watt alpine amp is running the front and rear speakers from the audio processor.

Had it dyno tuned the other week and the standard wastegate actuators that I put onto the -9's aren't controlling the wastegates properly at high boost, see dyno graph.

Runs well though and new actuators are on the way. Still running stock injectors and afm's.

Also going to replace compliance cat and sort out exhaust.

Steve-o, maybe....:happy:

Pete, I ended up getting the catch can from just jap in Kirawee, comes with the hose, I bought extra hose to set it up how I wanted it.

Bryn, I'm pretty sure the non vspecs didn't have em as the exhaust temp and intake temp is not shown on the MFD, I could be wrong though as nissan do some strange stuff too. You can fit the rear vspec dump to a non vspec....

      My hold point for future mods is that I want a OEM detachable hard top first, but, finding one is a pain, MX5 Mania are looking for one for me, but, as hens teeth are more common, finding one in Australia is proving problematic  I can get a OEM one from overseas, hell, you can still get new ones in 'Merica, but, shipping is a absolute killer and I cannot justify the cost, or the risk of it being damaged during transport As for the aftermarket hardtops, whilst they do the job of being a hard top, and are fine for a track car, they don't seal well (read: leak like a sieve in the rain), and you need a plastic/poly rear window, plus they are a bolt in option only and not made to be easily removed I liked how the hard top on my NB could be fitted, and removed, by myself, in less than 5 minutes I know it sounds bad, but I'm waiting for someone to write off a car with one so I can swoop in on their pain, it will go to a good home though, so my guilt of this is tempered

      No, you don't want to plug the vacuum line, as that will turn that side of the booster into an air spring and probably make it feel worse. I'm not saying that the GTR master itself doesn't need a booster. I haven't paid attention to the GTR one to know what size it is cf the non-GTR ones. But when you think about it - they have to do the same job, which is to move a little slave piston a few mm to do what it is supposed to do, and that final action is the same on all the cars. So, it is very unlikely that the GTR MC is any different than the others, because it has the same pedal stroke and the same output requirement. The booster just makes it feel easier. I'd suggest you probably have an actual hydraulic problem. It's totally common on these old shitboxes.
