It is called a direct replacement. But it's not really. It is not like the tomei one. The tomei one is literally everything you need and more is supplied.

fuel tank gasket, bracket, pump, fuel pump sock, etc etc. EVERYTHING.

The walbro needs mods to wiring to fit, needs to be mounted, no nothing is supplied etc.

also, the walbro flow rate is not as much as it says - their rating is not the same way of rating it as other pumps.

The tomei flows HEAPS. like crazy amounts. I can't remember when i converted it, but it was somethign like 270 lph.

A walbro is normally about $150.

One of our fellow guys who's in the same situation as us - installed turbo, changing pump, getting tune in a bit, has just got a tomei pump. For $340, it's pricey, but it's a massive pump, it's brand new, and it fits straight in.

Cheers

you on msn matey? My msn keeps signing in and out - mum took my computer, and i've got hers here. It's a pos. Also, it's the old msn, so if you're in appear offline mode, I can't reply. grrr, stupid pos comptuer

yeah im on now

if u get the r33 gtst kit for the walbro it comes with the pump, the rubber mount to use in the stock cradle, a new hose for the top of the pump and 2 new hose clamps and the sock on the bottom of the pump too

only mod needed to do is cut the old positive and negative wires and join the new ones with either crimps or solder/heatshrink

but as stated, if going for higer power go for a tomei as they flow much more

the kit was about 190 delivered from ebay, gss341 i think the part number was

tek, you didn't mention that the tank seal normally expands when you take it off, and it miht not go back on properply.

The good thing about the tomei pumps is it comes with a new one of those.

I can't remember who, i think it was either bass junky or abobob, did a test on the walbro, and it ran dangerously low on flow - they aimed the return line into a bucket.

I have experienced the same with the walbro. I have had 2 in my car and both were the same. Last time i had the car on the dyno i was running a flow / pressure test on the return line and found the flow went down to .2 litres per minute back to the tank on full boost.

These pumps are not very good at holding pressure they can do it for a short while but lose there flow.

I recently had to turn the boost down to 9psi because the pump started failing. got myself a 044 last night to chuck in.

Apparently these pumps are more of a non high pressure pump - they can flow high HP on non efi systems that dont require alot of pressure.

So for me walbro will make a nice pre pump for the 044 :(

Tomei pump for me as already stated - $340 delivered from Greenline.

Didn't want the Walbro as too many experienced people have had issues with them.

Bosche was looking OK but for $230ish, i'd rather pay the extra $110 and get i higher powered, direct fit replacement.

Considering it's made to fit with rubber seals on the bracket, it should run silent to.

This from nengun site : 248 L/h (Standard 136 L\h)

That's nearly double !

Installed a Walbro the other day, not difficult at all when compared with the mucking around required to install a Bosch pump.

With regards to the pumps having problems, any good workshop should tell you the stock wiring won't really do for this pump. I gave mine a good ground and it works fine, though it's not being pushed with just over 200rwkW.

Although to be honest, the only reason i didn't get a Tomei/Nismo pump is i couldn't wait a few weeks for them to arrive (stock pump failing)..

I can't really comment on walbro vs tomei, as I'm not a skyline specialist but with the walbro pumps as was already stated you can get a kit for it.

There are 2 types of walbro pumps, the GSS341 and the GSS341HP - High Pressure. The standard pumps do not handle high pressure very well, rather than explain, here's a graph that shows the difference:

d_885.gif

The walbros are extensively used in the USA with high power Supra's where they run multiples for higher HP applications without any issue. Personally I like the idea of a high pressure 255lph pump with fitting kit for a cheap price, I just finished doing a group buy on the supraforums for $165 for a direct fit kit delivered, you can't really beat the price compared to other pumps.

walbro pumps are rated at 255 L/hour, but in tests, at the voltages our pumps run (not at like 16-17 volts) and at the pressures we run, flow is no where around that.

Govic, for the stock turbo, pretty much any pump will do. We're going for more power.

Jase, looks like i'll be going for the tomei too.

Food for thought for you guys - the nismo and tomei pumps are both top notch products. However, which one is better, flows more, cheaper etc :) Now that's a fun one

    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers) Replacement of the Valve body (if you removed it) is the "reverse of assembly". Thread the electrical socket back up through the trans case, hold the valve body up and put in the bolts you removed, with the correct lengths in the correct locations Torque for the bolts in 8Nm only so I hope you have that torque wrench handy (it feels really loose). Plug the output speed sensor back in and clip the wiring into the 2 clips, replace the spring clip on the TCM socket and plug it back into the car loom. For the pan, the workshop manual states the following order: Again, the torque is 8Nm only.
    • One other thing to mention from my car before we reassemble and refill. Per that earlier diagram,   There should be 2x B length (40mm) and 6x C length (54mm). So I had incorrectly removed one extra bolt, which I assume was 40mm, but even so I have 4x B and 5x C.  Either, the factory made an assembly error (very unlikely), or someone had been in there before me. I vote for the latter because the TCM part number doesn't match my build date, I suspect the TCM was changed under warranty. This indeed led to much unbolting, rebolting, checking, measuring and swearing under the car.... In the end I left out 1x B bolt and put in a 54mm M6 bolt I already had to make sure it was all correct
    • A couple of notes about the TCM. Firstly, it is integrated into the valve body. If you need to replace the TCM for any reason you are following the procedure above The seppos say these fail all the time. I haven't seen or heard of one on here or locally, but that doesn't mean it can't happen. Finally, Ecutek are now offering tuning for the 7 speed TCM. It is basically like ECU tuning in that you have to buy a license for the computer, and then known parameters can be reset. This is all very new and at the moment they are focussing on more aggressive gear holding in sports or sports+ mode, 2 gear launches for drag racing etc. It doesn't seem to affect shift speed like you can on some transmissions. Importantly for me, by having controllable shift points you can now raise the shift point as well as the ECU rev limit, together allowing it to rev a little higher when that is useful. In manual mode, my car shifts up automatically regardless of what I do which is good (because I don't have to worry about it) but bad (because I can't choose to rev a little higher when convenient).  TCMs can only be tuned from late 2016 onwards, and mine is apparently not one of those although the car build date was August 2016 (presumably a batch of ADM cars were done together, so this will probably be the situation for most ADM cars). No idea about JDM cars, and I'm looking into importing a later model valve body I can swap in. This is the top of my TCM A couple of numbers but no part number. Amayama can't find my specific car but it does say the following for Asia-RHD (interestingly, all out of stock....): So it looks like programable TCM are probably post September 2018 for "Asia RHD". When I read my part number out from Ecutek it was 31705-75X6D which did not match Amayama for my build date (Aug-2016)
