Isuzu reliability tester
I was wondering if anyone has heard of high hp numbers out of the 4bd? What is the highest hp/tq? Do you guys thing 250-275 is an unreasonable number?
I'm aiming for around 200 hp, from turbo and exhaust mods for around 30 psi boost, air to water intercooler and fuel injection pump adjustments.I was wondering if anyone has heard of high hp numbers out of the 4bd? What is the highest hp/tq? Do you guys thing 250-275 is an unreasonable number?
I think 200 will be enough for what I want. I do some long off road trips to remote areas and reliability is important. I would be concerned about the head gasket at higher boost pressures, without o-rings. My intention is to use ARP studs and a little more tightening tension than stock recommendation for a 4BD1-T.I could be wrong but I bet 200 should be fairly easy to get with the mods you plan on doing. I have already talked with my local injection shop about modding the pump and the injectors they have been researching what can be done and say that my goal shouldnt bbe a problem. I just wanted to hear from people like you that have or are doing it. I didnt know that arp made head studs for our motors. hmm I may needa set of those.
Have you called comp cams to see about some custom valve springs, or to see if they have any suggestions?
The fuel pump delivers up to roughly 120cc/1000 shots without any internal mods.so dougal what do you think I could make hp/tq wise with the HY35, intercooler, and turning pump screws?
I will get the local injection pump shop to mod the injectors and IP later if necessary.
Not yet, but I have been far too busy with other distractions.Hey bush did you ever find any valve springs? I have been way too busy messing with this fueling problem to even look, just curious.
The air enters the slots in the tubes, passes over the fins on the outside of the laminova core, and leaves though the slots on the opposite side of the tube.Okay, first off that looks like quality work .
But I'm somewhat confused (or maybe not, it's why I ask), the air runs across the tubes laterally, and the water flows through the tubes (inside the "Laminova intercooler cores")?
