Overheating & brake issues when turbos dumping

Hi, I have had another engine fitted in my mitsubishi 1994 twin turbo since then, if you have to brake whilst the turbos are dumping the brake pedal goes to the floor, you have to pump it. also it has not moved for a good 6 months i got it going today, and the fans dont kick in and it over heats,and the over flow boils over, i took the termostat out and clean it, and boiled it up and it looked to be working, put it back together and still over heats and fan not working,
any suggestions,

There should be a resevoir for the brakes that prevents that from happening... it's either not hooked up or leaking/failed. as for the fan.... locate the relay for the fan in the fuse panel engine compartment near the battery and replace it... if that doesn't work you need to do some troubleshooting ... starting with the fans actually working... to power to the sockets for the fans

The car runs well, but just as the second turbo is about to kick in, it disengages. This is at about 4,500rpm. Although the engine will rev higher, the turbo punch is lost. I was adviced to check for a...

Hi David,
Sound as if you have a problem with the dump valve opening too soon. Both turbo's should operate together not in stages. If you have twin turbos there will be one for each bank. The dump valve is a flap which opens when the compression becomes too high. Its operated by vacuum via a diaphragm with a lever operation. You'll be wise to have both units attended to and set so they operate as they should.

HI I have an 89 supra with a blown 3ltr turbo I would like to know if the 1jz twin turbo will fit on my 5 speed and will my inter cooler work with it do i need different engine mounts

yes the tranny will work and you need the 1j engine mounts as they are different. the 7mgte mounts will not allow the exhaust manifold to fit with the down pipe. your intercooler will work fine although i recommend replacement since you loose pressure if this is an original unit. hope this helps. please rate.

Can i fit a turbo onto a peugeot 205 1.8 diesel engine?

You can fit a turbo to just about any car, the problems lie in changing the inlet and exhaust manifolds to house the turbo of choice and supplying the turbo with oil and water to cool it, also if the car has a ECU getting it chipped to provide the right amount of fuel at the right time.
To be honest if you want a turbo car it is best to buy one with a turbo already fitted as it will probably cost you less to buy for example a Mitsubishi Colt Turbo (around £1500) than to fit a Garrett Turbo (around £3000 with fitting and manifolds) to your 205. Not to mention that the gearbox, brakes and suspension would need to be upgraded aswell.

Engine compatible

Yes. However it is a very expensive swap $5000 to $8000 to do it right. You will need the 1J or 2J engine, transmission, wiring harness, ecu, and alot of other pieces to do the swap. The engine brackets will need to be modified and you will have to upgrade your brakes. This kind of swap requires a good knowledge of the Toyota Supra and the engines. I do not recommend this swap for a beginner. A cheaper way is to take a 7M-GTE and upgrade the internals and turbo.

Brake failer when turbos are dumping

The brakes are on vacuum assist, if the check valve is missing or in the wrong direction, boost will pressurize the vacuum assist, and mess with your brakes.

Good luck,

Hi, I have a Pajero 2800 Turbo 1995 Auto. It has developed a bad oil leak somewhere around the front right hand side (from the front) where there seems to be oil spraying over the pipes, etc. Can't see it happening with the engine running and have cleaned the engine off but still can't see where it comes from. It has emptied the sump! Any ideas?
