Ah yeah didnt think about that. Once you have a 4" intake, the 3" afm will become a restriction and also annoying changing diameters if you did leave it there.

What options are there to remain with a 3" intake. I know simon you will recommend the 4" intake but think about it from a stealth on the street point of view. Is it possible to get an anti surge housing with a 3" intake on a GT30?

on another set up we did on a mates street car same turbo as mine mounted on stock manifold. used a 4-3inch black silicon reducer and painted black hard pipe to the AFM. cant really tell that its a 4 inch intake on turbo unless you look right at it.

Thats a great idea, do you think it reduced power?

This seems to be a restriction for people trying to use reponsive turbos but still make ~275rwkw.

I dont understand, how is that related to "R33 Gts-t Turbo Recommendation, most responsive for 275rwkw"

Because on the street it will be just as fast as 275kw with his laggier turbo for example, I think you could get 260kw out of it if you used E85 quite easily.

theres no way its a restriction.. you can flow 300 rwkw or even 350 rwkw of air thro 3 inch pipe no worries.. think about intercooler pipes and how they flow large amounts of air under pressure and yet are around the 2.5 inch mark

i have a apexi ax53B70, had it tuned the other day and made 240kw on 18psi with 555cc injectors, pfc, z32, 3" exhaust, fmic. but was told i wont get any more out of it. pretty annoyed as i spent just under 2k on it and was told i would see 250 with ease. although i am very happy with the response :(

how much does a 3071 go for?

do you know which version of the ax53B70 you have? there are two different versions the 320ps one and the 380ps one. You may have the 320ps one which would explain the power?

Ok so after going through this thread it seems the garrett 3071 turbo is the best choice since it can achieve around the 280rwkw mark with the least lag???

Im from perth, would anyone know a rough price for one of these? also does it bolt onto my intake and dump pipe?

I just dont wanna get my stock r33 turbo highflowed only to get bored of it down the track and wished i had'nt skimped out, and bought something a bit more expensive.

No chance in a straight line. Maybe on a really tight track.

The HKS 2835 Pro S is pretty damn responsive.

I think the HKS 2835 Pro S turbo wins the prize of most responsive turbo to make 275rwkw on 98 fuel.

+1

very happy that I went that way

much love for the anti surge housing... i have 4 inch hardpipe straight to Air filter (afm is on other side of pipework) and the spooling sound is insane! greatest sound on earth hahaha

i'm running a 4-3" custom metal pipe off mine and yeh... sounds awesome

use metal, paint black

Yeah Thats what i bought...will hopefully post some results soon...

you will need to modify your intake pipe..as its 3 inch...

for the kit..3k...new

if your lucky you'll get a s/h one for half that ..If your game enough to go s/h turbo route you'll get a good BB jobbie and there is plenty that will make that power...but buyer beware...

EDIT>>Actually just looking may as well get this for the same price...More power just as responsive..

Yeah in a drag race the outright power would definitely win but around the street and tight hills it would be very close.

Seeking an opinion on this one. Like the price! Going for street use and response over max power.

Is that for an RB25? That wont make anywhere near 275rwkw on an RB25.

I think it will be too restrictive and lack any sort of top end. Just use a 0.63 housing on a GT30 turbo and it will be super responsive and wont restrict the top end as much.

do you know which version of the ax53B70 you have? there are two different versions the 320ps one and the 380ps one. You may have the 320ps one which would explain the power?

yeh i found out after getting it tuned i have the one with the smaller exhuast housing

use metal, paint black

When doing this do you still have the AFM mounted on the intake side? Or in the cooler piping?

If on the intake do you get any problems with reversion?

    • Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.  
    • 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.
