Tb42e power and response up grades

[Alitis007]

Sorry fellas 300 would be the absolute max it was more of I dont want more than that 200 to 250 would be ideal and im not talking at the wheels so im guessing around 190 at the wheels would be where it probably ends up I think from memory the tb42e is roughly 145 standard no doubt its lost around 10 over the years. By taller gears you talking diffs? Or gearbox? Or both? Im gonna change my 3.9s to 4.3s as ive still got the crown and pinions from my old rb30 I dont want to go bigger because I already have 4.3s ive set my car up so far on an unbelievable budget to get it where it is she is a very heavy girl at the moment George. Power isnt my main concern but as I understand you cant just add torque with no powergains. Thats why I am asking you blokes as I have no knowledge in this field. I really want response off the pedal and torque obviously in my mind power has to come with that. Am I right or wrong? Id much prefer a supercharger as thats gonna put the torque up more than a turbo I think but then again the turbo is cheap. im fn confusing myself now. Sorry if Im making no sense

Why wouldnt a 4.2 carb exhaust fit on a efi?? Or even a td42 set up obviously no dump.

efi extractors need a o2 sensor bung mate, they're only worth $5 so if you got a cheap set off a carby or td you could just drill and weld in the bung.


Yeah heals, i was talking diff gears mate. Mist people go turbo coz it's cheaper to setup even tho a charger would work better i haven't seen many, actually 1 td42 with all plasmaman gear on it. I was pretty sure the tb42 had 125kw at the flywheel so probably only around 80rwkw if your lucky lol. I can see that your doing what you can for sweet eff all mate but that gt42 is a massive turbo and wouldn't start spooling till 5k i rekon haha . Anyway mate your pretty limited with what you can do without spending a fair few $$$ but imo you should forget about power figures for now and focus on what the long term use of the truck is going to be to work out how your going to set it up. Think of torque as pulling power, the more torque you have it should accelerate faster and hp/kw is the by product of that at the peak of your rev range. Imo for now just fit the diff gears, that should make it quicker off the line and make it a bit more responsive for the time being. BUT remember everything is about sacrifice so tall diff gears will make you have less top speed, more power = more fuel consumption so work out what you want so you can find the happy medium.
