Your going to be in for some serious fun when you do open it up :w00t:
If its anything like mine the rear will break traction in the wet or the dry and for some reason it gives you quite a big smile :laugh:
Got to have a look at my fueling as i/ve just done 16miles and it cost me £10 in fuel hock: Have a feeling its the silicone hoses i've fitted to the engine, as before it was ok, but since they have been on the fueling has gone terrible? so not sure if there too soft for vacuum lines and there closing up under pressure??
So might fit the oem set again to see if it makes a difference? cant see what else it could be as the rest is still the same as it was before? God help me when i turn up the boost cared:

Interesting that you're having problems with water pumps. Are you using original Toyota/Lexus pumps? We have had some guys doing engine swaps on MR2s and once you change the water system around it can put additional strain on the water pump (certainly in the MR2 there is further to pump the water, more water, etc). The pattern pumps people are fitting from motor factors are not up to the job. Admittedly this is with the 3.0 V6 engine.
Are you using the original radiator for the engine or is it a larger capacity/thicker? I assume with the turbo mounted directly next to the radiator the water temps are through the roof. I'd be putting SPAL fans on the radiator (you will probably create big problems with having the fan on the FRONT of the radiator as it causes an obstruction to natural airflow) and look at what temperature your thermostat is opening at. TRD thermostats open at lower temperatures which could be also useful in your situation, just to get things circulating quicker.

toxo OK. My point still stands about the water pumps you're using. These are 2 pumps for the 3VZ-FE:
Note the difference in impeller design. Left hand one is blueprint (Toyota is the same) right hand one is QH.
Not all water pumps are created equal :thumbup1:
Hi mate, i have only just put the new pump in, so time will tell if its as good, but it did look the same as the old one so thats a good start.

toxoI'm just going by how they look here. The right hand one looks a lot stronger, but the left hand one seems to have *much* bigger vanes, and even though it has slightly less vanes than the one on the right, it looks like the one on the left would have a better flow ? I could be totally wrong of course.

You're pretty much bang on. Both work fine in a Camry but when you put them in an MR2 the one on the right doesn't flow enough due to the impellor design. QH don't see it as a problem because their pump works just fine in a Camry which is what it was designed for, but I would assume that the wheel is a semi-standard part that's used on a variety of pumps.
Of course you don't run into these problems if you buy genuine :thumbup1:
Thread hijack over I hope the car goes well this weekend, don't wanna be stuck in a tunnel trying to get water back into it!! I've had to do that in Rouen in a friends car before...
