Hey guys.

Currently in process of installing Nismo intank fuel pump on the 33. Working off the tute in the diy section. Everything was going to plan until i put the new pump back in the hole. I cant find the spot to actually mount the bracket inside. When i pulled the original pump out it didnt appear to have the mount part holding onto anything either. It is sitting right at the bottom of the tank part. Am i pretty safe to close it all up and leave it go? Or is there issues this could cause (maybe like fuel surge if the pump moves (even though it seems fairly steady).

Secondly. With the black ring that you have to tap around (with wood and mallet by the tutorial). A few of the tab bits are starting to dent a bit. Has anyone come across a better method to tighten the ring over the lid???

Thanks for any help.

ps if anything doesnt make sense im a bit "fuelled up" atm. :) lol.

Cheers Luke

ive seen pics of people using big multigrisp on the ring thing. god that gave me the shits putting it back on. too fiddly to get off centre.

also, it may take a lil while to get it on the mount. took me around 10mins of constant trying. you'll get it eventually :)

Thanks for the help guys.

Pump is in. Car is running again (cant take it out of the street to test as No interior or seatbelts atm. and i dont have a milkcrate to use as a makeshift seat :(

For peoples future reference. My ring was getting a knocked about trying to get it back on. (No funny comments there please ;) ). Ended up putting a bit of inox on the inside thread of the ring. Went on like a dream, then secured fine once tightened.

Literally took about 2 minutes to finish off.

Cheers. Luke

Well. The car finally left the garage with the new pump in tonight. Running fine. Ive read the nismos are fairly quiet. This thing sort of howls. lol. Admittedly with no back seat or sound deadening. But wow. Sounded pretty tough though i must add.

Is it normal for nismo pumps to be approx double as loud as standard??

Secondly. I know i dont need a tune straight after getting the pump done. But if the car was running perfect before the pump. Am i fairly safe to be revving it right out on the new pump without affecting tune at all???

Thirdly (full of questions tonight). With a power goal of approx 250rwkw. On the Nismo pump should i be doing the wiring upgrades to make the most of it??

With a power goal of 250rwkws, you'll be fine with that pump as is, no wire upgrades.

As far as tunes go, if your tune was fine before, and you've upgraded your pump.....all i can see happenning (and that's a maybe) is you'll be getting slightly more fuel which is actually safer so rev to your hearts content.

just make sure you did secure the pump to the bracket inside the tank. otherwise you are going to get fuel surge issues and possibly damaged/dead pump eventually.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel

      What should I do next to hold the head on

      By MBS206 · Posted

      When you pulled it off, there is no signs of blown head gasket? Is it possible you have some other issues going on? Possible cracked blocked? Or do you think it's straight up lifting the head? Did you check what the head was torqued to before pulling it down (To see if possibly they're stretching, or starting to break threads out etc)?

      Chris' Toyota Mark ii JZX110

      Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.

      If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
