I want to do a spot of modyfying to the inlet manifold and will need to stick it back together when i'm done. Does anyone know what grade of ali the manifolds are made from or what grade of tig filler rod i need?

At what kind of boost levels does an RRFPR become necessary? I'm only looking to run low levels 5-7psi on factory ecu and injectors to start with. Will i need an RRFPR?

I'm looking to use a bypass valve from a mini cooper that has an M45 blower on it on an M90. I can't see a reason that it shouldnt work - have i missed something?

What length of snout is needed to clear the water bridge? Theres an eaton m90 come up at a good price but the snout length is 195mm from the outer face of the pulley to the ring of bolts that fixes the snout to the body. I've had a quick measure and it looks very close.

The fuel circulating round the fuel rail sounds like a toilet cistern filling - i'm assuming this is not right? I had a bit of a moment when i piped the fuel lines in and mistook the rail buffer for the PRV and piped it to the return. The pump ran but locked out when it got to 11 bar. Would...

I have an engine and gearbox out of a soarer in my rover p5, It turns over but fires only briefly ( couple of seconds ) and then dies. It looks to me like a fuel problem. I put a gauge on the fuel line and found it to be running at 50psi which i believe is too high ?? I have a correct fuel pump...

I've put the engine and gearbox out of an sc400 in my rover p5b. I'm just doing the last of the wiring - i want to use the neutral start switch on the gearbox but cant find a point to wire it to. I was going to make the NSW connection on the ecu +12v and use the output from the neutral switch to...

All of the inlet manifolds for roots type superchargers i have looked at dont have provision for the idle control motor. Bullet can add this at extra cost. If it isnt added, how is the idle controlled?

I have an engine out of a 1990 soarer in a rover P5B that i want to supercharge. I am looking at fitting a rotrex charger on the lextreme fish bracket. I dont have any room at the front of the engine to fit it the usual way round so it would have to be fitted with the pulley facing forwards and...

Do engine mounts have to be the same both sides? ie symetrical? One side has to have a dogleg in it to clear the steering column so do i mirror it on the other side? cheers

Whats the oil pressure when hot at idle? The pressure switch that i have off the rover switches at 8-10 psi. I'm trying to keep the look of the rover interior as stock as i can so didnt want to fit a pressure gauge but need a bit more warning than 8 psi! It looks like the switches are 15, 20...

I want to use the original temp gauge on the rover which is a 10 volt jobby, so i thought i would use the rover sender on the lexus engine. What temp does the water run at in the lexus or what temp stat is used? Cheers

What fuel pump flow rate do i need on a stock engine? Dont plan on any extra power for the foreseable future, so i wanted to fit a pump that wasnt massively overated.

The o2 sensors that are on the manifold foul on the subframe so i want to move them further down the system. Theres only one per bank ( with a single wire ?) How close to the engine do they have to be? Can i move them further down with no ill effects? Cheers Neil

I want to connect a temp sender for the gauge on the dash, is the efi sender the only one? If it is, is there a plug somewhere on the water jacket i can remove and fit a sender? my gauge is working on 10v so really need to keep it seperate from the rest of the system.

Hi, Am looking to transplant the engine and gearbox out of an ls400 into a 1968 rover p5b. After a good measure up it looks like it will fit. The intention is to buy an ls400 and remove everything i need. The mrs will only let me have a wreck on the drive for a week, so i have to get all i need...
