More Power From 12ht. Thread starter jack doff Start date Jun 8, Is there someone out there who can tell me how to get more grunt without compromising my reliability or blowing up my motor?

Joe Active Member. You can add an intercooler. That will give you a few more horses. I have a snorkel, a 3" mandrel bent exhaust and am running 10 psi boost. I dont seem to be getting much more power than stock. Does an intercooler make that much difference? Its a lot of cash for a maybe. Split pin Active Member. Basically an intercooler will cool down the air going into the motor.

Intercooler come in two styles air-air or water cooled. I prefer the air-air type with a fan. An air-air intercooler looks like a radiator.I was in disbelief that anyone would want to use something so slow and noisey. I asked why and they said it used less fuel than the petrol equivalent and the fuel was cheaper.

Ok so I had my answer and yet always wondered if the sacrifice was worth it. At about the same time I was given a book for my 12th birthday on formula 1 cars.

I was very interested in the engine sizes and quoted power. Well, it was and many were turbocharged…. Wow a miracle power increase…. I have always been interested in internal combustion engines and followed the history of them.

Later when I could buy my own vehicle, my quest was to increase the power. After a few naturally aspirated engines I bought a small car with a turbo, EFI and a Haltech programmable computer. This is where I first did programming26yrs old. Detonation at 14psi was an issue so I added water injection which allowed an easy 18psi on 91 octane.

But the detonation still bothered me and I realized Diesel engines were immune to it. Gturbo can upgrade fuel pumps, injectors, install chips, intercoolers and exhaust systems, and most importantly tune the vehicle to suit the modifications.

They also refurbish fuel pumps, and will tune based on your specific requirements. Not everyone wants the same sort of tune. Gturbo uses a Dynocom AWD, with a single large roller for accuracy and all wheel drive capacity. Give him a call; I guarantee you will be impressed.

Yep, you read that right; the old Nissan engine was ditched in favour of one of the best engines Toyota has ever made. Boost is a minimum of 32psi from rpm. AFRs start to finish. Safe to over 35psi. Nov 13, — our race VDJ79 rwkw. This is a production class vehicle so we are very limited in what we could modify and only had 10 days to do it including an engine swap. This is a beast.

This has been running around now, doing long trips and towing for months. Very responsive. Makes 20psi at rpm, psi by rpm on road. Awesome towing? Turbo capable of over rwkw. No fan assistance on intercooler during run — tuned for worst case.

The 12HT fuel system is a little different to its baby brother the 2H, where the fuel is controlled by a governor in the rear of the pump, making it a very responsive and torquey engine.

The pistons in the 12HT are a lot stronger and run a steel insert between the no. Transplanting a 12HT into your cruiser is very simple with very little needed to be changed. The gearbox bolt up is the same, and the engine mounts will swap to suit both the wagon and tray back.

As per every performance-related mod there are trade-offs involved: so you will need to work out at which end of the spectrum you eventually want to be i.

I would also suggest getting the brakes thoroughly inspected and making sure they are working as well as possible. This isn't the ordinary 4wd or toyota mechanic - it needs to be someone who can check the injector spray patterns, overhaul the pump, test all the pump pressures and test the compression on a diesel engine.

Ideally it should be someone with a rolling road; because you need it tested through the rev range. I know this sounds "boring" but these engines are getting old now so getting the basics right is important. Also you need a baseline for your build. However, the pistons were manufactured with a softer than ideal seating area for the top ring.

This means the natural cycling of the engine causes the rings to wear this groove to the extent that, after some time, they will become loose and score the bore; eventually jamming the engine. The evidence appears to suggest that this occurs somewhere around ,km.

However, in vehicles that have spent a long time idling e.
