RE: 4DL TZR Engine Unmaintained!

Ahh ryt yeah that makes sense. I thought the S was supercharged? Or is that what you meant?

What pressure you running? Me and my brother bought Toyota Starlet GT Turbo. His is running fair bit more than mine. TD04 Billet Aluminium Hybrid turbo at only 0.5 Bar at the moment. Even so it still made 200bhp on the dyno. When you think the car only weighs 800Kgs then you can imagine the thing absolutely flies!

No its the later gen 2 turbo charged, 23psi, only small mods atm, but keep adding more mods, future mods, bigger turbo and intercooler, 3" downpipe and sports catback, probably miltek :)

Nice, That's quite a lot of boost. I'm running Zero boost atm, mainly cause the heads off. Jokes. I don't know what I'm running, but don't imagine it being that much. I need to get the motor running first lol

Can't have too many projects ;) I want to buy a rolling dt to fit my spares to

True that. Have you seen my CarPc project lmao. Got over 100 games built into a custom computer in my car. Sega Genesis, Snes. N64. Ps1 :D Doom, Quake...good times.

Yeah I just want to do one at a time, not juggle them all.

Just wondering is the tzr 4dl bottom end much different to the 3mb dt engine and is it worth sitting the antenna top end to it? The bottom end will be rebuilt of course and run the zeeltronic ignition I'm building a engine with plans to buy a project dt125r, currently have a 95 model completely standard untouched only done something silly like 4300 miles from new but would be a shame to spoil it, any help with the bottom end would be well appreciated Thanks Andrew

I wouldn't go out my way for a belgarda 4DL unless it's an SP. In which case you won't want Athena.

I don't rate the athena kits, you get more torque but lose overrev and they're pretty killer for the bottom end.

The 4DL gearbox I had was no where near as good as the stock DTRE box. All round I prefer the RE engine. But this was a great project.
