3tgte ra28 help

[boy28racer]

.
Hey all, last year i purchased a ra28 with a 3tgte engine conversions.
After getting it home i realised that the ct20 turbo was in need of a rebuild. once it was overhauled i went through the things that will need to be changed to get mod plated.
.
The prevous owner had put a surge tank in the back, so to get the car road legal i have removed it. Now the car wont kick over im not sure what problem is? does anyone have any idea what it could be?
.
thanks

If you took the surge tank out whats feeding the high pressure pump now? The outlet and inlet for a 28 tank is at the top and high pressure pumps don't suck.

As per stidnam's post, but I would like to add a bit more.

A surge tank in itself is not illegal. What is, is having it inside the cabin. If you simply move the surge tank in under the vehicle, then there is no problem. You should have coming out of the tank, a low pressure filter, followed by a low pressure suction pump, which will then feed into either the surge tank, or the high pressure pump directly if you don't have a surge tank.

After the high pressure pump, you will have a high pressure filter, into your fuel rail, then out of the fuel rail will be the pressure regulator, which will feed back to either the surge tank or straight to the fuel tank. If you have a surge tank, then it will have an overflow feed back into the fuel tank.

On top of all that, you need to keep your charcoal canister as it will stop the fuel tank from pressurising.

So things to check
1) do you have fuel in the tank?? Silly mistakes are often the ones which trick you the most.
2) do you still have a suction pump in the system to feed the high pressure pump - and can it out-flow the high pressure pump (remember that the return from the fuel rail to the surge tank normally negates the need to have such a large suction pump)
3) did you wire the fuel pumps back in?? IE do they run when they should (turn the ignition key on and jam open the air flap in the AFM and it should pump (if it works the same as other Toyotas from the 3T-GTE's era)

I would say move the surge tank under the car and put it back in. Fuel pumps and lines in the cabin are a no-no too, so don't expect that pulling out the surge tank is the only thing you need to do.

Thanks,



I think I could have had someting unrelated (to fuel) fail as motor
should run without good pressure. Have re-checked pump etc.

on the fuel pressure thing I am thinking I need good reliable fuel
pressure, how I go about it is the thing, another surge tank (just
about no room under RA28) or retro-fit a twincam pump into my
tank.

If I get no joy can someone recommend anybody in Brisbnae
(Northside prefered).

Thanks

have a look at rod's (the toyman75) ra28. He has a real neat fuel setup under the car. I think linden (the real road runner) may make these up and may be able to send one up.

[stidnam]

Rod's setup will only work if you decide to go a side pipe exhaust. Linden has done a few others though including mine where all lines coming off the surge tank inside the car are hard lines while the bottom of the surge tank is outside the cabin where all the fuel hoses come off it. The whole setup is built around the well behind the drivers side rear wheel. Its rather neat and no fumes in the cabin
