Toyota Chaser Turbo

Hey fella's, just had a thought.

They say the JZX100 2.5L 1JZGTE vvti single turbo model has the largest turbs of the toyota range. It has a T3 flange on it too which means it'll bolt up to a standard rb20/25 exhaust manifold. Obviously the dump flange is different to a gtst turbo, so fitting one will require a different dump and possibly changes made to the intercooler piping.

So does anyone know if they're any bigger than the r33 rb25 turbo? Flow more etc? Good/crap upgrade/downgrade?

It has the much hated ceramic turbine wheel, and can't safely be boosted above 14psi much like the skyline turbo's. Buts thats all I know.

I'm probably answering my own question, but i suppose it comes down to if it does actually give an extra 15rwkw, is the price you pay for the turbo, dump fabrication, front pipe modification, intercooler piping modification, oil and water fittings actually worth it? .......Probably not.

Flow less. Are a POS.

Mate has a chaser, stock turbo, with exhaust and FMIC, it peaks out of flow at around 5500RPM.

They are not as bad as you think as in stock form they turn out more torque than the earlier rb26detts although they have 1 less turbo and 0.1L less displacement...

Although i'm interested to know...when it peaked at 5500rpm...how much power was it making? Because the r33 stock turbos also peak soon after that point...if the chaser turbo makes power regardless then it probably isn't a crap turbo...its just not viable for us...

You make good points. As far as my knowledge served me, the chaser is faster than a gtst/25t/gtt out of the factory, and is a heavier car(not by much), but has the same displacement.

No there was a single turbo version (2JZ) as well with some form of CTxx turbo .

Really?? Are you sure - I most definitely haven't heard of that. The 1JZGTE was twin and ended up with the single turbo CT20B if I remember rightly, which seem about comparable with an R33 GTS25t turbo from all I've seen.

What car used this version of the 2JZ? i thought only the Supras and Aristos came out with 2JZs and they both ran sequential twins...didn't know there was a single turbo 2JZ from factory...can anyone confirm this?

      Stock rb25det neo questions

      By joshuaho96 · Posted

      I mean yes, if you're starting from scratch on an unknown engine yes you don't need to be doing all kinds of math in the background but if you're doing relatively minor changes like AFM + injectors + boost up with some aftermarket turbos it takes quite a bit of math if you want to do something like maintain OEM fuel + timing tables but compressed and then a bit more load scale up top. I think I've spent too much time working on big engineering nightmares though so I'm a big fan of trying to constrain the scope of whatever work I'm doing as much as possible and trying to get it right before moving on. For example, a local owner just did the usual E85 + single turbo conversion to his R32 GTR and nearly burned his car to the ground doing some spirited driving up the local mountains. Turbine is unshielded and too close to the hood insulation. It's tough to balance "just get the project done" and "seemingly small details can cause massive setbacks I'm not willing to deal with".

      Neil's R33 Gts-t Build

      No idea about Neil's steering wheel, but I have the same behaviour in the Stagea. I doubt it has ever been messed with so might be normal. Indicating to turn right at a roundabout and correcting even a little bit to the left to go around will cancel the indicator. Never considered it an issue other than it being a bit odd.

      Does anyone know if this is off centered? Looks like it, when I indicate to go right, but turn my steering wheel slightly left it cancels (was always like that even before I started messing around with it) was wondering if anyone else has the same issue?

      Nothing photo worthy since last update, lots of little plumbing bits for the AAC/Cold start valves, and unfortunately I still need another couple of parts for the brake booster line and the AAC into the plenum. Otherwise it all looks good to start up engine wise, onto checking the electrics/interior
