Diesel Boost Compensator

Boost aneroid you mean? 

Heaps of jokers with TD42 non turbos add the aneroid setup from td27s, so I guess it's possible. 

If you're merely lookign to turbo your existing engine, you don't *need* to run an aneroid. essentially all they do is limit fuel until the engine is making sufficient boost to support it. in effect a smoke limiter, but the lack of aneroid can be looked at as causing EGT spikes too. not a big deal really, if the nanosecond of gross overfuelling frightens you just lean into the gas pedal gingerly off idle/in laggy situations etc.

After a quick search the general consensus on ORE seems to be swap the RD28 for an RB30DET (tempting) or buy a truck with a TD42 lol

 

Yeah aneroid/boost compensator/manifold pressure compensator/boost modulator etc for some reason I thought they were pretty much a "must have", I'm starting to collect bits to turbo the Gloria, 40k max uphill is getting old real fast! haha.

Will check out some other pumps when I can, might be easier though just to buy a factory RD28T aneroid from Aus.

Don't even bother man, it really isn't even a big issue.

 

Yowzer has so many fuels off boost and his egt's are are well within check.

 

exactly. plus without an aneroid you get mean coal rolls on gearchanges, and the 'egt spikes' aren't even a second long I'm sure. not enough time to actually transmit through to components. 

I guess it's an issue on offroad shit where you might be lugging away off boost. overfuelling will be a huge deal there, but, for a road car, all good. just don't pull up hills at 1000 rpm at full throttle lol. 

 

in summary: aneroid will only limit your potential of rolling huge coal for lolz. 

If it were me I'd whack turbo on. wire wastegate shut. tweak fuel 'til it maxes the boost level out a psi or two higher than you want to run in the end (12ish psi without an intercooler I reckon would be a good level) then hook wastegate up properly to open at your desired boost level. I reckon you'd be about spot on with your egts then

 

also if you're going to do a choice job of it, build a decent exhaust and intake system to make the most of all this stz. my teranno was severely restricted in it's performance by the dump pipe/peashooter exhaust (plus the turbo wasn't really big enough but it would've done a lot better with a decent zorst) 

 

do rb turbz manifolds fit the rd series?

Hmmmm black smoke is a pretty good selling point for running with no aneroid...

No, RD28s have non crossflow heads so the ports are way different.

 

Tossing up between doing it quick and easy with a J pipe and no intercooler which should be easy enough to whip off for wof time, or doing it somewhat properly with a factory turbo manifold from Aus and getting it all certed.

Found an EGT gauge with probe for $25 shipped on Ebay, what could go wrong haha

I had a compensator added when I threw a turbo at our old B2200 work truck, it wouldn't return to idle properly without one. You should be able to use one off any Jap pump, though something is ringing a bell about a spacer now. I just used a diesel pump specialist.

Also no fucks are given about an added turbo to a diesel come WOF time, nor should there be. A 20% increase of fuck all is still fuck all.

Testing stations have never given a stuff, and my current guy is super tough and doesn't care.

I didn't get through with a turbo, it was all complete bolt on factory stuff but somehow I ended up with the only guy who knew about shit old toyotas and what engines they had.

Changing from NA to forced induction requires a cert regardless of power increase. You will also need driveshaft loops.
