Hey firstly I'm gonna get some EL dials....has anyone got any places to get them...I saw some at Autoshop.com.au for about 250..they looked good.

But more importantly I have just replaced my K&N pod filter with a ram-pod filter from Unifilter...cos they rock. I have this plastic duct that sits above the radiator to get some air into the boxed area but I wanna run a pipe form the grill somewhere to get cold air in. Problem is...I can't find a good spot to do it cos in that part of the bar its all sealed off and full...what has every1 else done for theior CAI setups??

Thanks

Chris.

when i put my FMIC on i ran some pipeing through where the old bottom pip was (now on opposing side of engine bay) it pops up riht under the pod, very little modification/effort required

yeah I would assume so...perfect spot...but cos I have a 34gtt side mount one I have no space...maybe a FMIC is on the cards :)

FMIC kits are so cheap it's a crime not to get one. Even 34 IC is a joke so get rid of it before you chase power and bust an engine Chris.

GTT cooler isn't thatbad?? :)

Did alright for me, plenty of others too. Plus if Chris isn't chasing crazy power figures at the moment, why spend the $500 or so for a kit??

ta razor...FTO brothers stick together hey :)

but I think the FMIC was on the cards regardless so guys don't stress....it wojld set me up nice for a wicked CAI...now the only thing is which FMIC is ok for the money???

and thx for the EL dial PM razor...I'm keen not to get the normal white dials like in my FTO...although my FTO dials looks pretty aswome...I have a aliminum back plate and not looking for AL rings for the dials...can't find them yet.

Not tasking a shot Razor but even a modest increase in boost can result in massive post IC temps. Most never bother to take the measurements.

Consider I measured post IC temps of in excess of 60 deg on a 27 deg day. This was with just 13psi. I then measured with the water spray on getting 37-42 deg. Improvement, but not enough and I discarded water spray due to space and inconvenience. I also cracked 2 pistons playing tag with a Porka. I pulled in close behind him (about 2m) and even with the water spray got detonation on full throttle because it lost sufficient airflow to cool the charge. Unfortunately at the time I didn't have the water injection setup.

I then installed a Hybrid 800mm cooler and with 14psi (and 220rwkw which I don't even remotely consider crazy power but sufficient for street) I was getting post temps of 31 deg on a 30 deg day. At under 60kmh it would gently rise to 36 but as soon as speed increased it would drop quickly. This is without any water spray or injection.

So a quick percentage calc of volume and mass of the 34 item would reveal an efficiency increase of SFA, whereas a small 600mm Hybrid or copy would gain size of over 400% compared to the 34 item and should be as efficient as the 800HP I run since it won't be pushing massive power. The 600 would fit fine but the 800 needs some trimming behind the standard bar and at $650 delivered complete with piping and brackets is a bargain http://cgi.ebay.com.au/HYBRID-INTERCOOLER-...1QQcmdZViewItem

considering I paid 700 for mine 3 years ago with just the IC then had to fabricate piping.

Besides, Chris is a good bloke and I don't want to read of him busting an engine when he gets the urge for some go when some crook tuner says "she'll be right mate. We'll keep it a safe tune!" with no idea of the temps created, so on a hot day it makes that innocuous little "tink tink"sound and a month later is blowing the dipstick out.

My attitude now is fix it before it's a problem, having now busted the engine in the GTS25t track car 3 times (last was one of the twin turbs shattered). Fortunately I do my own work so it's parts and machining.

RB25's are tough enough for decent power (Inasnt has 320rwkw on the stock bottom end) but very susceptible to detonation so just don't risk it.

      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

      I hear that would involve some nice country road drives into the hills for Mark...

      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?
