just bought one tonight... whats a good boost level to run a pretty much stock rb20det??

So did you get the one with the 1mm hole in it? Thats the best one is it?

I have a turbosmart manual boost controller I scored off a mate, are the Turbosmart ones better then the $25 item?

How do they compare next to the Turbosmart item?

Is this type a bleed valve boost controller? Because if it is I would say the ball and spring type would be far better.

A couple of pics installed on my MR2. Not sure if its right but...seems to be spiking. Could be the way i sealed off the stock solenoid lines.

Hey,

I just got my turbotech controller from Mark off of ebay (whitie_bear on ebay) and my controller doesnt have that tiny excess pressure hole drilled in the back like this one does!!!!!

Isnt that going to highly affect the performance of the controller, i have tried to contact Mark but still no reply, im sure he is busy but this is very annoying to me!!!!!!!!!

Are you sure you even brought it from Mark? When I brought mine from him his eBay name was simark87? Mine does not have the hole either and it works very well.

hole or no-hole better/worse is still up in the air a little. If it works good on your car, great. Go with it :) but don't write it off just because there is no hole. Try it first.

i drilled a 1mm hole in my mbc and i have noticed if i accelerate slowly but still let the engine rev right out boost will slowly climb up to 15-17psi and hold there but if i smash the loud pedal staright to the ground boost will shoot up to 13psi and hold there.

got me confused...

anyway.. mine is set on the GTR to 10psi and its feels pretty good. its something like 9.5 but spiking a little.. full boost earlier..

still waiting for the S14a to come round and install on that :P

also has anyone had an issue with this controller..? eg. overboost dramatically.. clog up..kill turbo? etc?

i've never had an issue with it. it always holds boost perfectly.

there was one stage where i had heaps of lag, but that turned out to be my cat. changed it, problem solved.

i'm still happy with no hole. since there's no lag, and response is super quick, i'm happy to leave it alone.

so how did u find hole vs no hole? did u do the r34 yet?

rather than reading back thru 72 pages, can someone who has already read them let me know if its worth running them on r33 GTR at 19psi?

what turbos u got. hope u dont wanna run 19 on the standards..

ive heard of people running 24psi and over on these. so year go for it.. :P prob contact mark first.

    • I have no hard data to report, but I have to say, having driven it to work and back all week, mostly on wet roads (and therefore mostly not able to contemplate anything too outrageous anywhere)..... it is real good. I turned the boost controller on, with duty cycle set to 10% (which may not be enough to actually increase the boost), and the start boost set to 15 psi. That should keep the gate unpressurised until at least 15 psi. And rolling at 80 in 5th, which is <2k rpm, going to WOT sees the MAP go +ve even before it crosses 2k and it has >5 psi by the time it hits 90 km/h. That's still <<2.5k rpm, so I think it's actually doing really well. Because of all the not-quite-ideal things that have been in place since the turbo first went on, it felt laggy. It's actually not. The response appears to be as good as you could hope for with a highflow.
    • Or just put in a 1JZ, and sell me the NEO head 😎
    • Oh, it's been done. You just run a wire out there and back. But they have been known to do coolant temp sensors, MAP sensors, etc. They're not silly (at Regency Park) and know what's what with all the different cars.
    • Please ignore I found the right way of installing it thanks
    • There are advantages, and disadvantages to remapping the factory.   The factory runs billions of different maps, to account for sooooo many variables, especially when you bring in things like constantly variable cams etc. By remapping all those maps appropriately, you can get the car to drive so damn nicely, and very much so like it does from the factory. This means it can utilise a LOT of weird things in the maps, to alter how it drives in situations like cruise on a freeway, and how that will get your fuel economy right down.   I haven't seen an aftermarket ECU that truly has THAT MANY adjustable parameters. EG, the VAG ECUs are somewhere around 2,000 different tables for it to work out what to do at any one point in time. So for a vehicle being daily driven etc, I see this as a great advantage, but it does mean spending a bit more time, and with a tuner who really knows that ECU.   On the flip side, an aftermarket ECU, in something like a weekender, or a proper race car, torque based tuning IMO doesn't make that much sense. In those scenarios you're not out there hunting down stuff like "the best way to minimise fuel usage at minor power so that we can go from 8L/100km to 7.3L/100km. You're more worried about it being ready to make as much freaking power as possible when you step back on the loud pedal as you come out of turn 2, not waiting the extra 100ms for all the cams to adjust etc. So in this scenario, realistically you tune the motor to make power, based on the load. People will then play with things like throttle response, and drive by wire mapping to get it more "driveable".   Funnily enough, I was watching something Finnegans Garage, and he has a huge blown Hemi in a 9 second 1955 Chev that is road registered. To make it more driveable on the road recently, they started testing blocking up the intake with kids footballs, to effectively reduce air flow when they're on the road, and make the throttle less touchy and more driveable. Plus some other weird shit the yankee aftermarket ECUs do. Made me think of Kinks R34...
