Nothing has happened for a while but it kicked off again recently. Will be same same but different. Complete PRP and MoTeC catalogue thrown at the car. Will keep you updated

The real Don Mega huh? ?

Sounds like you are challenging me for the most overcapitalised RB20 in history.

It's different when you're connected

I know what happens BTS.

I am also well connected ?i much prefer wasting my own time and building everything myself that wasting somebody elses time on an RB20 ?

Funny you're still not powered by a 4G63T haha

[iruvyouskyrine]

Haha they are to reliable for me. Need that stock 30 year old Nissan 'will I make it where I'm going or will I break my oil pump halfway there' feeling to keep me comfortable. It does annoy me how quickly they spool turbos though and Benny has got them dialled.

It's the stroke and the head, light years ahead of the Nissan boat anchors.

Might need your services one day to convert to DBW, install a couple of hall effect sensors and get traction control going ?

[iruvyouskyrine]

I would convert to DBW in a heartbeat if the only real option to keep the ITB setup wasnt 4k AUD. It's so so much better than cable its stupid. I have never dabbled with kebabtech traction control but with MoTeC it works flawlessly ?

[Komdotkom]

I must win the over capitalisation contest then, my RB20 is DBW!

There was talks of someone on this forum using the ITB DBW from a BMW on this forum, but not sure if it materialised. Maybe you can be the first hahaah

Mines just a single TB on a Plazmaman intake, not the ITB setup so it's nothing fancy. This is from last year.

any particular reason for converting to DBW? do you now have cruise control or anything?

[Komdotkom]

It's a race car and has Motec everything so DBW is used for idle control and I'm a big believer 'in if it's worth doing, it's worth over doing'

I wanted a forward facing TB and would have had to purchase a larger unit anyway so there was essentially no significant cost difference between DBW and a cable throttle.

You get to piss off the idle control valve and aux air control valve (both are slow and lazy).

@Komdotkom any plans to run traction control?

Yes, it's got most of the Motec catalogue in it so runs just about everything you can think of. Just missing tyre temp sensors and suspension position sensors I think.

At the moment it runs 'traditional' Motec traction control strategy but I was considering a DBW TB in the intake pipe after the IC to bleed off boost as a form of TC which was very effective because it doesn't impact engine speed an efficiency as much as other strategies. A mate ran his IPRA car like this with excellent results.

It makes me so mad that a genuine Bosch DBW throttle is only about $400 installed and that its 10x the price to do it on ITB, sadpanda.you go 68 or 74mm?

It was Stephen from IEE and even after talking to him it was still the best part of 2.5k AUD and that was before the 'rona and AUD tanking. I just decided to absolutely tap out my M130 instead haha.

You running M1 or gold box? Would need M150 minimum to run that or a DBW4 unit. Unless you plan to run it as an actuator on a DHB and have no feedback loop?
