Both me and a mate are running small ex housing GT2871R's on FJ's. While I havent had a chance to lean on the setup yet, my mates FJ 1600 has been running 216rwkw @ 16psi for quite a while, mainly only been used for track work. Super responsive with minimal lag he loves it, I'm just hanging to get mine running similar.

something like a gt3076r with a .69a/r exhasut side would be perfect for a mild FJ, should see you past 300rwkw

Thanks guys

I've also been recommended a GT3071R with 0.6AR compressor

Pardon my ignorance as I'm not up with turbo sizes but will these bolt on and is this an equivilent to a GT3071R ? http://www.digi-hardware.com/tr43gen2.html

The manufacturer recommended this but the internal wastegate is optional plus I was worried it was too big.

I assume the std turbo has internal wastegate?

R34, The non intercooled FJ had a .63A/R rear housing on a T03 mount flange. The intercooled FJ had a .48A/R.

As it's fairly well known, I bought the DR recently from Qld and I'm going to use it as a track/hillclimb car.

The sky is the limit as to what you want to do, but the first thing you do is punt the ECU and get an a/mkt tuneable unit, then bigger exhaust, then bigger or more efficient intercooler (bigger isn't necessarily better) then injectors, all depending on your budget.

I think personally a 2871R is too small as I think it will run out of puff up towards the red line.

I'm going with, as stagefummer suggests, an GT3076R with external wastegate and .86A/R rear along with 3" exhaust & 550cc injectors in a custom O'Ring fuel rail. With this I'm looking towards 400+HP at the wheels and then your problem is getting it to the ground effectively.

My only concern with Hypergear is it sounds too cheap, remember all of the Monsta T70 turbos that flooded ebay a couple of years ago, they were claimed to be ex USA but in fact were coming out of China, into USA and then to OZ and they were farked, would not spool up at all. Just be sure what your buying as cheap usually is.

Cheers, D

Yeah Dennis

I'm looking at Autronic SMC or Vipec now.

Would aiming for 400hp create a problem with lag?

:P

Had a rally Mazda years ago and built it with small periphial ports rather than go for the big ones of the all out power monsters.

Section of the rally up the side of the Darling scarp (Zig Zag) beat all the other Hi po Mazdas and the works Stanzas (Dunkerton,Fury) and Works Fords (Carr, Bond)

One rare claim to fame for a poor privateer but taught me to chase low down power too

    • Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
    • Hi guys, has anyone either purchased or built themselves a rotisserie for their car before? I can only just justify the need for one hence why I should just make one but at the same time, if I make one I can kiss another 4 weeks of potentially productive car working time goodbye because I'm building a bloody rotisserie....  I mainly want it for the application of the body deadener.  Cleaning the old stuff off, priming and then colour over the deadener doesn't worry me, it's just the application using the Schutz Gun that I feel would achieve a significantly better finish painting it side on and keeping the Schutz Gun upright.  I don't think they would work well on the side let alone almost upside down for some areas.  If the product I use (Terosun, etc) could work through a HVLP ok then it might be ok to apply without the rotisserie.   I can get one of these style ones for about $1200 which is pretty good value-     I reckon if I made one it would cost around $500 but it's more the time that it would take is more of a killer than the cost.  They look to hold their value pretty well second hand so I could always sell it after using it and realistically only lose $200-$300 at worst.  Or keep it and buy another project when this one finally sees the light of day... Anyone selling one...? Cheers!  
    • While it is a very nice idea to put card style AFMs into the charge pipe (post intercooler, obviously), the position of the AFM and the recirc valve relative to each other starts to become something that you really have to consider. The situation: The stock AFM is located upstream the turbo, and the recirc valve return is located between the AFM and the turbo inlet, aimed at the turbo inlet, so that it flows away from and not through the AFM. Thus, once metered air is not metered again, neither flowing forwards, or backwards, when vented out of the charge pipe. When you put the AFM between the turbo outlet and the TB, there is a volume of pressurised charge pipe upstream of the AFM and there is a volume of pressurised pipe downstream of the AFM. When the recirc valve opens and vents the charge pipe, air is going to flow from both ends of the charge pipe towards the recirc valve. If the recirc valve is in the stock location, then the section between it and the TB doesn't really matter here - you're not going to try to put the AFM in that piece of pipe. But the AFM will likely be somewhere between the intercooler and the recirc valve, So the entire charge pipe volume from that position (upstream of the AFM, back through the intercooler, to the turbo outlet) is going to flow through the AFM, get registered as combustion air, cause the ECU to fuel for it, but get dumped out of the recirc valve and you will end up with a typical BOV related rich spike. So ideally you want to put the AFM as close to the TB as possible (so, just upstream of the crossover pipe, assuming that the stock crossover is still in use, or, just before the TB if an FFP is being used) and locate the recirc valve at the turbo outlet. Recirc valve at the turbo outlet is the new normal for things like EFRs anyway. In the even of a recirc valve opening dumping all the air in the charge pipe, pretty much all of it is going to go backwards, from the TB to the recirc valve near the turbo outlet. But only a small portion of it (that between the TB and the AFM) will pass through the AFM, and it will pass through going backwards. The card style AFMs are somewhat more immune to reading flow that passes through them in reverse than older AFMs are, so you should absolutely minimise the rich pulse behaviour associated with the unavoidable outcome of having both a recirc valve and an AFM in the charge pipe.
    • Yep, in my case as soon as I started hearing weird noises I backed off the tension until it sounded normal again. Delicate balance between enough tension to avoid that cold start slip and too much damaging things.
