what do i need for total boost control

[GTR R35]

hi all,

I would like to know what EBC I can use that will allow me to run 0-20psi boost on a R33GTR?

My wife is not used to manuals and I do not want her to get into any trouble, so I want to set the boost at say 1psi for her, but I want 20psi for track days. I do not need any bling bling just full control of the boost.

Thanks

Mal

avc-r is the way to go i got one last week

what aza said.

AVC-R are the best.

I dont think you will be able to set it to 1psi. I think you can only go as low as the factory actuator.

[JNR24]

thats right, lowest youl be able to go is 7PSI

[rob77]

Yeah, with the boost controller turned off it will just go off what the std spring in the internal/external wastegate is capable of holding to

[Zombie]

Maybe a boost controller that will allow you to make the boost come on very slowly and not until up in the rev range.

Nah - just tell her to keep the revs down till the boost comes on. Short shifting.

Get an adjustable actuator to set it less than the normal "factory' setting. Depending on the actuator used you could effectively get rid of all boost.

This will need to be adjusted manually between driver swapping though, could turn out to be a big pain in the arse real quick

You could also just disconnect the actuator, a much quicker job. I don't know how healthy this will be for your wastegate/turbo though, because it'll probably be flapping around a hell of a lot.

Thanks for the replies people,

I was wanting something that would drop the boost down below factory specs, but I am guessing I would need something with an electronic wastegate/actuator and that would equal big $$$.

Tha AVCR looks to be the go, do I need a specific model to use on the RB26DETT ? They seem to be costing around the $750AU for a new one, but I did not want one that was for a different model motor and want to make sure.

Are they also user install or do i need it pro installed and then dynoed ?

Thanks all

best to get it installed/setup by a pro. Here in adelaide i was quoted ~$250 (for install/tuning). It suits many types of cars, not brand specific. I've got the "vehicle specific wiring diagrams" book sitting in front of me (come with the AVCr when u buy it) and the Rb267dett is listed.

[JimX]

Depends on how competent you are with the iron. I installed my S-AFC myself and I've removed/replaced the turbo myself, I don't imagine a boost controller would be much harder than combining the 2.

There are no tuning costs if you don't have a reprogrammable ECU or piggyback device (S-AFC etc), but don't expect it to run very well until you get one and tune it

[Bl4cK32]

Yes, but setting up is critical - can lead to blown turbo/engine.

there very easy to put in it took me 1 1/2 hours to put in from opening the car door to taking the first run down the street just take it to some one who has one to show u haw to us it the boost setings r very low so u cant realy do much damage if u dont play to much with the set up but just dont give it to it to much till u have been shown haw to us it

AVC-R look good but they r only single solenoid and old.

Get the profec b spec II, its got dual solenoid, digital boost gauge, overboost warning etc.

[Lunatic Dancer]

yes but with the avc-r you can set boost for each gear and rpm range..and ye u cant set boost lower than lowest on wastegate.

install you can do urself with a bit of skill and tuning you can go dyno or with a mate and long stretch of road

if u only want hi / low setting then profec b spec2 is good buy..

its still a single solenoid unit, it displays injector cycle etc but if u got a pfc with h/c u can see that anyway.

So so many people have stated u can set boost in every gear but has any1 actually done it??? coz how does the avc-r know what gear u r in?? it doesent get a signal from the gearbox.

[4 Doorz]

am interested to find out more about this gear specific boost settings as I am looking into getting a avc-r ... this option would be the deciding factor, if it does actually work

[Bl4cK32]

Right ppl. I have in front of me the AVCr instruction manual. I haven't had it installed yet (due to engine dying week after I bought it - different story). The Avcr has a number of different learn modes. Its pretty complicated, but there is a wire for the revs and a wire for the speed signal. It uses some sort of calculation from these two values to know what gear its in

Yes it would work - cos its in the Manual. Just need someone in the know to set it up fo u.

[calvintys]

get HKS evc ,,,,i haven hear anybody complain about it,.......and it simple to use but not the latest evc 5... too complicating... alot of GTR us that for track ....if you guys not sure ... just ask around
