hi guys

i recently just put an r33 turbo into my r32

but now its overheating, and im assuming its because of the coolant lines that go into the turbo,

i noticed that the bolt have a special hole in the middle to feed the coolant down into the turbo,

my guess is that its not lined up properly.

how do u know if its lined up properly?

cheers any help is much appreciated.

The bolt is a banjo bolt and the coolant feeds from the line into the holes in the side of the bolt.

There are galleries to feed it through so you will have have coolant going through there.

So your engine is overheating not your turbo?

It may be that you have a coolant leak? check levels

Was the coolant bled properly?

thanks guys so theres no way that the hole in the banjo bolt can be blocked if facing in any direction,

i just bleed the system,

seems to run alright not overheating like last night but the tempreture reads weird.

goes from 80-90 down to 60-70, like jumps up and down

thanks for the comments guys

You may need to bleed it again, It can take a few goes, did you end up dumping the

radiator aswell, If not there might be an air pocket waiting to get out, but usually it does not take

to long to surface, Failing that if you keep getting,radical temp changes, I would be looking at the thermostat.

Yeah, the banjo bolt does not need to line up with anything, just install it.

It sounds like you have an air pocket in the coolant system. Did you bleed the system via the 10mm bolt in the plenum? Its the highest point in the coolant system, so the air will escape here when bled properly. This is an important process as differential heating of the head can lead to cracking or warping of the head.

      R32 GTR Lost All Interior Power to IGN Accessories

      By Kirby7887 · Posted

      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.

      Mistakes were made, my R34 Story

      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.

      Factory oil temp sensor in a RS4V without gauges?

      By MBS206 · Posted

      Sounds like the oil pressure light is wired into the oil temp sensor... As it warms up, resistance on temp sensor reduces, hence more current can flow and the dash light gets brighter.
