I was just about to say, TO4 means about 20 different turbos. Even diesel ones.

I cringe when people go in about to4 or even worse, some bullshit t3\t4 crap combo they have no idea about at all.

Why? TO4 can mean any of a shitload of turbos?

yep, that is why I'm asking, cos I'm not so sure what it is.....a hiflow can be anything and we are allsaying that its being choked and I tend to agree, but I'm not so sure that the turbo is any good period, not just the hot side but the whole lot.

I'm not disagreeing with you, I agree, and that is why I'm asking. Just cos he says it is a T04 and its been hiflowed doesn't mean jack.

hey guys sorry about the lack of knowledge of my turbo but here is my dyno sheet. we have fixed our problem its holding 18 pounds again we just need to get it re tuned. turns out the actuator diapraphm had a tear in it and was leacking boost. ill let you all know what happens with the next tune when i get back from this dam work trip....

i cant get hold of my specs on the turbo but i have the standard r33 rear housing that has been re machined and i believe its 6 mm bigger than standard size if that means anything to u all the wheel in side was changed but cant remember what size it actually is. its not just some random turbo as i have family that works at mtq and has actualy made the turbo for me sorry about the lack of knowledge tho. sorry to cause any arguments with this next post but yea cheers for all the help its much appreciatedpost-79355-0-75899900-1312949653_thumb.jpg

      New fix for low tyre pressure from bmw

      CTIS (Central Tire Inflation System) has existed since the 80's. I'm looking into buying a Hummer H1 and they generally included it.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      My idle is set at 950rpm though - Moving the timing around 20 degrees is not really what I'd call a calm idle. That said... neither is chop, by definition. The LS ECU likes to adjust timing to hold idle as opposed to air. It'd work, but generally speaking there'd be a discrepancy in the base idle and the IACV would want to move the timing around anyway to maintain said idle. I think I'm just going to keep the timing steady anyway. Preserve my engine mounts.  My aircon is now officially regassed. As the guy was reversing I noticed my reverse lights do not operate, along with my reverse cam. This is a bit distressing, because 100% of guides talk about which wire to connect to backup cams as "the goes with the [other color] wire". Often when doing conversions. Unfortunately the R34 colour wires aren't documented Unfortunately I had a T56 Magnum gearbox with it's reverse switch, which also isn't documented. Unfortunately there's definitely not documentation for people with both of these in the one car. Unfortunately I forgot. After many hours of this, I have a reverse cam and reverse lights again. The wire going through the trans tunnel to the reverse switch had broken. Upon inspection, it looks like this one wire had about 7 spade terminals and extensions in it.. for reasons I cannot possibly comprehend. I also spent the 750 hours required to clean up the wiring behind my head unit which now looks like this: This is a monumental improvement relative to what used to be there WRT triple gauges, head unit, traction control, wideband controller, and whatever the f**k OEM stuff still exists there in various states of connectivity/needed. Next step is to check in at the Exhaust shop to see/confirm how much clearance I have, to decide what mid mufflers or 'resonators' (which are just straight through, narrower mufflers) I can add and hopefully cut out a lot of exhaust leaks, pinhole, v-band or otherwise. But first step will be to 'take a look' before the next step.

      It's most likely the bolt/bush where the cover bolts back wore and allowed cover to move forward.

      Still haven't put the injectors and R35 AFM in so we can tune the bloody thing for the HG highflow it got mid last year! I think I can forecast the upgrade path to a bigger twin scroll, external gate, Haltech, flex setup, Samsonas, dis dat, etc will be .... a while away!
