No the first place you could ask is me .

Which FJ20 inlet manifold do you want as there are two DR30 variations and the S12 Gazell type .

The one I used in the Bluebird I had 4 cars ago was the slightly larger plenum volume early version . I removed the external EGR log from the lower side of the runners and the throttlebody flange was removed and welded back on at a better angle for the old birds intercooler plumbing .

I have all three and their native fuel rails and FPR's from memory so drop us a PM and make an offer .

In Syd , cheers A .

BTW still have all sorts of FJ20 odds and endz looking for new homes ie Gazell engine mount brackets (v hard to find nowdays) Gazelle thermo housing , loom, Gazelle turbo exhaust manifold and cast dump pipe (no fire wall mods) and these dumps have the waste gate integrated unlike the DR30's extra flapper plate and small bore bolt on elbow , intercooled DR30 ECU , odds and endz .

There is a lot of miss information about inlet manifolds and in this case the std DR30 manifold is not as bad as many think .

The ultimate system is individual throttlebodies and is why Nissan used them on RB26's and the GTiR spec SR20 .

Still while the Japs race 9-11000 rpm drag engines the copy cats think its the way to go .

Actually thats only partially true, the RB26 was designed to compete in the up to 4500cc touring car class.

And as such was a curcuit car engine firstly.

ITB's give better response,not necessarily more power.

I guess it depends on exactly what you are trying to make.

A drag car would want 1 large t/b over itb's.

The other way around for raod/track car.

    • 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.
    • I'm almost at a point where I feel like changing the alternator. Need to check the stuff you mentioned first though.
