Bom dia,
I have a '89 Toyota Bandeirante with the Mercedes Engine and got 'em a turbo upgrade like 4 years ago. Since then I'm driving this setup without issues.
When I was installing the turbo, it took me quite some tim, because it wasn't a Plug'n'Play kit or so and I had to upgrade some other stuff as well. I spared out the intercooler back then.
It's a unregulated turbo which delivers around 15PSI of boost at redline limit (and less at lower RPMs). The engine was never build for turbos, so I do not have a boost controller, I just cranked up the diesel a bit and drive like this. I watch the EGT closely (EGT Meter before turbo) and try to keep the black smoke little by avoiding a heavy foot at low RPMs.
Once in a while I' thinking about the intercooler and I could need some piece of advice from you guys:
1. I know, that there is no additional power just because of the IC, but it will thematically relief the engine a bit
2. How big will the drop of EGT be? Like roughly?
3. If I crank up the fuel further to meet the same EGT as before, will that be a big difference?
4. Any fuel savings?
The successor of my engine was build with a OEM turbo and was delivered in different versions and the turbo alone had something like 110hp and the turbo+intercooler went up to almost 140hp. I somehow doubt, that I can get up there. I have right now around 85hp on the rear wheels with around 20hp-25hp loss in the drive train and wheels (acc to the dyno).
I would go for a more or less similar IC-size as the 140hp engine and squize it infront of the climacooler. The electric fans would need to go, not enough spare and I would need to bring the radiator a bit back anyhow.
What you guys think, worth the effort? Cost wise I would end up at around 450USD roughly, building the kit myself and get some stuff welded by a local shop.
