hey guys I'm after a 5/8 to 3/4 hose reducer for my heater (20 to 25 conversion) but I can't find one anywhere. I've tried pirtek, plumbing stores, hardware stores and a bunch of car stores but have found nothing. Does anyone thats possibly done the conversion know where I can find one (well 2 actually)?

i just used half of the original 32 heater hoses (ones that go through the fire wall) cut them off, fillted 2 5/8 straight joiners from bursons. them fitted 5/8 blue silicon heater hose onto the engine. they are fairly tight but with a bit of vaso they go on ok. I didnt use the factory pipes that go across the bottom of the inlet manifold tho.. i just joined them straight to the block if that makes sense lol

Ah so basically the silicon 5/8 could stretch enough to fit over the 3/4 outlet / inlet?

Seeing as your in SA, head to GRH supplies at South tce Wingfield (use to work there), ask for Laurie. They have an extensive range of brass fittings and should be able to make something up to do the job! :blink:

Tell him James that use to work there sent you and he'll look after you!

I wouldn't go streaching the hose, gives it a much higher chance of splitting as it makes the wall thickness thinner!

Yeah mate thats right, just have to get the "blue" silicon hose. Bit of lube and they go on piece of piss.

If you didnt wanna do that then id say enzed, pirtek, hartrite etc etc will have the stuff you need

    • The SS button head cap screw on the back? If so, good to know. I presumed it was there for basic assembly and nothing more. 
    • Hello, everyone. I'm new to the forum. I have a 1989 Nissan Skyline R32 GTR. I have lost all power to the interior, including AC controls, the gauge cluster, turn signals, and windows. Stuff that still works includes the horn, brake lights, radio, and headlights. All fuses, in the interior and exterior boxes, tested good.  It starts and runs fine, just with no gauge power or anything stated above. No warning lights either. Things that I have tested: - Fusable link tested fine - No other fuses blown - Alternator good - IGN switch tested fine - With my power probe, I can backfeed power through the IGN pin to the plug on the back of the gauge cluster, and everything comes back on.    So my theory is something on the control side that sends the ignition power through the system isn't doing its job, or a wire is broken. (I would think that it is the ignition switch that would do that, but who knows?). The ignition relays don't fire (all relays tested good). So what tells them to fire other than the IGN switch?  I would really appreciate it if someone had some insight on this. I have tons of hours into this; I don't want to give up in defeat! I have the HD wiring diagram, but having all those wires laid out like that on one sheet of paper makes things pretty hard to follow.  Thanks for reading, and thanks for the replies.  Where should I look next? Thanks.
    • Install a MAP sensor pre and post throttle. Best data you could have for NA, then play with the bends and/or air box and see how much of inflection is created at WOT on the plot.

    • The car remains in paint jail. I am now pretty convinced that the whole "RB25 Airboxes are kinda limiting to ~300kw" could be a thing. Also saw a good video from Engine Masters: (Sorry for FB link) (https://www.facebook.com/watch/?ref=search&v=761771519471924&external_log_id=c10bcbb6-2c39-4ff3-9240-287e9921fde6&q=Cold Air Considerations) Where they tested Pod Filter sizes and kept adding bends to a LS3 on an Engine Dyno to find if bends caused power loss. It's a good video worth watching - They did lose ~25hp from making an intake which had 3x90's and a 120 degree. They only lost maybe 1hp with a basic 90. I feel that by sealing up my airbox I have: 1) Created the same restriction a stock airbox would have. 2) Created a very convoluted set of intake 'pipes' by forcing all the air through the ducts. So I am pretty confident I'll be going full circle and have a huge hot air intake pod and actually see a benefit. The air does *not* stay hot once it gets flowing, aided by the ducts, and the pod can then pull air from anywhere. All the posts of yore talk about the stock airbox costing 10-15kw at 300kw+ but you know what? I f**king would very much like that 10-15kw and I remember my own pod filter in engine bay experiences. Turns out the GTT Reo and Headlight brackets really don't allow you to mount GTR items, no matter what the internet says. Various brackets have had to be made up to actually make it fit right for the front bar. Also some idiot mounted a 3L Accusump right where the bumper wants to go, so that has had to be 'relocated' To where, I am still not sure, but it's supposedly mounted in the pictures and I can't see it.
