Built b series drag race Honda, full race top mount kit.  only turbo changed- no other changes.  

Green line = 9180 1.05 a/r
Red & blue = 8474 1.45 a/r

This is from the blue DC2, right?  I was told that this is running an EFR9280 now, and that this comparison is comparing the EFR9180 with the EFR9280.... in fact, if there are no crossed wires then there is a pic of this car on the Full-Race FB page saying it has an EFR9280 now

I am also looking for a T4 1.05 External gate twin scroll housing for EFR7670 if anybody knows of one for sale.

Part number is 12701019047

I am unsure if all B2 turbos use the same 'D type' rear housing that i am looking for or if it is specific to only 7670

Thanks

It would be turbo specific to fit the right sized turbine wheel.

Any idea is that direct swap from 8474 1.45a/r to 9280 1.05 a/r without any exhaust work?

Between the 1.05 and 1.45 housings is 7 mm. The dump has to move back 7 mm, it doesn’t matter if it’s a 80 mm wheel or 74 mm wheel.

Ok. . Thanks. So 74mm 1.45 to 80mm 1.45 they should be direct swap. 

This is a great thread,

After reading a huge chunk, I have a question for all those high hp setups running 8373 and up.

What exhaust are you all running on these Skylines?

Reason I ask is because I ran into flow issues on my little track built EVO X running 8374 (IWG) with a 3.5" straight through race exhaust, we removed it and ran with downpipe only and made 30whp gain at only 1.6bar boost. I can only imagine how much more power you can make with a side plant (exhaust cutout operated with a valve). I'm installing one now...

I was looking to upgrade my 8374 to a 9180 but now thinking after reading this I'll go to a 8474, my setup is sleeved block 2.2ltr (4 cyl obviously) with direct port meth injection, sequential 6 speed, head work, oversized valves and makes over 600awhp on a mainline dyno (I flew the boys from Powertune over to tune it). peak power is 8500rpm and I get 2 bar of boost by 3,900rpm in 4th gear. Car weighs 1280kg after stripping it (with roll cage) and being built for Sepang F1 circuit.

'little' evo.

You can plumb an exhaust in if you actually plumb it further back (and not lose power), but realistically when you've gone to the degree most people have in these kind of builds it's venting to atmosphere and everyone prefers it that way.

Hi Robo,  thanks for using our EvoX turbo kit.  2 bar at 3900rpm is excellent for the 8374.  What exactly are you looking to acheive and do you have any reason why you would not want to go external WG?

In the case of a RHD evoX, there is less room than LHD.  As you know, the steering shaft area is your space constraint from using a large diameter downpipe.  Dumptubes for an external WG can be tough to package - but doable.. depending on what your exact goals may be will ultimately dictate the piping configuration.  you are welcome to email me directly to [email protected] and ill do my best to help

    • HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.
    • The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.
    • Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?
    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
