Got my Version 9 Spec C motor in and running.... only to find an oil leak at the external oil cooler unit on the block. Damaged in shipping, so I had to order one from the UK. Was nice to see it start and run for a minute without CELs. Running a Ver 8 ECUs for now.

I think the benefit of the OEM style is having the throttle response given the large reservoir right in front of the throttle. Turbo lag is negligible but the throttle lag does exist with a FMIC. You can tune around it with a little more spark, etc. but it *DOES* need to be considered when you tune the tip-in.

EDIT: Hyper - are you logging pre-throttle boost in that photo? That's a great place to do it that I hadn't considered, but for anti-lag tuning, I've been brainstorming where I want to stick the tap.

What I *really* wouldn't mind having is a restrictor with something like this built-in so I could measure PR and hold it around 1.8.


yes, it goes directly into the autronic map sensor
honestly I can't say I noticed any added throttle lag when I added my lateral FMIC setup. I can see when it can become an issue with long piping and a core made out of soda cans

that's a cool restrictor, never seen one like that before, we've always been using a long trumpet copied from prodrive grN

I've got 3 and haven't really noticed any difference in how they perform:

1. Prodrive 33mm aluminum (N15)
2. TMR 34mm steel (N14-N15)
3. STI 33mm long aluminum (N14-N15)

As far as I can tell, the only difference is which inlet you want to run. The STI long one needs the STI inlet while all the others work find with the Samco/Prodrive.

Update for those buying twin scroll engines: the newer style GDB JDM twin scroll down pipe is the exact same length as the USDM downpipe, so you won’t need anything besides possibly an adapter for the 2.5” donut flange in the down pipe to your car-back if it has a 3.0” flange, for instance.

This is facts, I bought a jdm exhaust only to find my dp was too long, I had an exhaust shop cut the 3" off and reweld the flange on the dp. Now I'm stuck with jdm length exhausts.

The twin scroll down pipe of a ver 9 is long and equal to our usdm, the twin scroll down pipe on a ver 8 is short as is a single scroll down pipe of a ver 7.

Correct, because I swapped my V7 to twin scroll from single scroll, I used the tomioka twin scroll usdm length dp. Nice piece and performs well.

Hey everyone,Side question:
Kinugawa wastegate actuator for the vf36, preload is 3 full turns? I found one reference to this but wanted to double check... 1.2 bar spring if it matters. TIA.

I went off their site for a baseline to start with but it was pretty far off, you'll have to readjust it as you do logs to find where it should be set at.

Baro is internal to the ECU or potentially read by the MAP before starting. Never bothered to check, but it's one of the two.

So if im running my usdm ecu, on a jdm motor, what would be the way to solve this? Finding the baro sensor from the old 255 and connecting it? Or is there another way around it?

only thing you have to worry about is passing emissions. Most don't connect to the jdm ecu's. Unless it's a track car then it doesn't matter. Just do the normal maintenance stuff and go on your way.
