32Gtr Help Needed With Walbro Model And Thermostat Gasket Part Number.

[roadhazzard1]

Hey guys I know this has probably already been answered or at least half answered but I am struggling to figure out the right fuel pump to replace the stock one in my 32GTR.

Looking at the Walbro 255 the problem is when ordering it gives me 2 options in the 255lph flow, the GSS342 255lph high pressure and the GSS317 255Lph OEM pressure. The car has standard rail, fuel reg and injectors although the injectors and reg are getting changed within a month when the haltech gets fitted just want to do the pump for peace of mind as I think its still stock.

Do I need a better fuel reg to run the high pressure version of the Walbro 255 (so can I fit it before reg and injectors get fitted) or is that the one I should be using regardless of regs and injectors.

The second query I have is doing a full coolant flush of the block. I understand the tutorial the only thing I cant find when ordering parts is the gasket part number for the thermostat housing is this just a silicone gasket u make I assumed there would be a gasket. The only one I could find was a complete replacement housing that came with a gasket.

Thanks in advance the forums have been beyond helpful so far srry for so much text just trying to answer any possible questions.

I can help with any injector/pump questions...

I would be running the 255, (the 341 and 342 are identical other than where the sock fits) actually I run two of them currently. Better would be the new 460L e85 pump to allow for further power later. What are your power goals anyway?

Give me a PM when you get price quotes on your injectors/pumps, I can get rock bottom pricing from the wholesaler...

As for the housing gasket, I would be buying the entire thing, it is a sacrificial anode and as such usually corrodes badly.

Thanks for the quick reply. so is one of the pumps socks location better suited to a stock cradle in a 32 gtr? I was considering going an e85 pump although i am not in a city so availability is still a few years off for us unfortunately. aiming for anything above 250kw at all 4 with more boost and the haltech fitted. maybe 300kw at all 4 one day. It has a 33 gtr engine fitted with 33 N1 turbos so was planning on a safe 16psi? wat injector size would u recommend for just over 300kw at all 4 max on the standard rail and wat is an ideal reg upgrade, thanks mate
