    Whats this Turbo then...VIDEO ADDED!!

    As its a laggy ******* low down as explained below...




    Is seriously laggy till about 3-3.5k then just pulls like a train.
    Engine runs outta puff before it does..Yet its only making 12psi?
    Exhaust housing is unmarked,an definately not T2,looks japish to me>?

    Really wanna improve the off boost performance but dont wanna cam it,jus get it spooling up quicker but keep the Top end

    Any ideas fellas

    Cheers all

    Re: Whats this Turbo then...

    If you want to improve the lag then maybe have a T2 .35 rear housing fitted, to be honest it doesnt sound too bad when your turbo kicks in now but each to there own

    Re: Whats this Turbo then...

    Like i say jus seems toooooooooo laggy for me...but my concern is it feels like its been limited if you know what i mean..feels like it could do a shed load more boost as when its on boost it aint sweating,yet low down its ****e. made 153 @fly on 12psi,turbo feels like ita take 20psi,better actuator needed first though

    Really wanna combine the best of both..Hence id the turbo and hopefully find what its capable off....

    Re: Whats this Turbo then...

    Yes that turbo will feel more lively if it runs more boost, set it to around 15-16psi with the carb rejetted to suit and you'l find it abit more lively for sure.

    Main/idle jet have been taken out too next size...Jus found believed reciept for it...Turbo technics stage3 hybrid(T25/T25)...

    But no-one can say what sorta psi it can handle...as im only running a standard actuator on it and a cossie cone(will be dropping that a touch me thinks...)

    Well it will all depend on the wheel trim size and what rear housing it actually is but i'd say you'll be fine right up to 20psi, maybe abit more.

    Do you know what jet sizes in your carb?

    The stage 2 t2/25 from turbo technics that I had could run 22psi fine. 360degree thrust bearing should be in yours also so see no probs with you running 20/22psi.

    The TT 'Stage 3' is a very laggy turbo. I had one years ago. When it finally came on boost though, it packed one hell of a punch. I sold it to Adam L (from Turbo Developments) who agreed with me. He, like me, got a bit fecked off with the lag, so he fitted a smaller back-end, and said that transformed it into an immense turbo. A lot less lag, but it still punched very hard.

    It might be worth chucking him a pm, and asking what back end he fitted, as I can't remember

    I think those jets will need changing alittle, no need to take main out larger you'll prob need to enlarge 2nd stage abit and reduce the ac abit. Checking the AFR's will tell you this mate

    Check you got the right size restrictors in the breather pipes still, I see you still running the breather into the air filter hose and wrong size restrictors will cause a noise like that

    Re: Whats this Turbo then...

    could there be a leak on inlet manifold or around that area, also check the non return valve of servo

    spray a bit of carb cleaner around the inlet side ,see if the revs pick up

    although revs hunt when this happens

    hmmmmmmm yes i did

    which hose needs a restrictor fella, one from rocker cover to breather pot or the two that split from the air filter and go to pot/an inlet?

    just to jump on this thread.

    I had this problem when I went to silicone hoses, forgot to put restrictors in, put them in, noise went.

    my new setup doesn't run a pipe to air intake pipe, so can I loose the restrictors? will it change anything, better to run with them or without

    You still need the 1.7mm restrictor in the T-piece to nrv line...or do away with the nrv & associated pipework altogether, and run the 'Cup' breather setup instead.

    Yep, it does away with the restrictors altogether.

    Blank off or remove (and then plug) the breather nrv from the inlet manifold, and do away with all the breather pipework & gubbins, bar what's shown in the picture above.

    The '2L' item is a catch can, but an old lemonade bottle or the such like will suffice - Just make sure it's breathable as such; ie, don't 'seal' the pipe into the bottle.

    Right done all the cup mods, NOISE GONE


    But ive 2 new probs...1, idle mixture is stuck at 10 On AFR, wont budge off mixture screw, so im assuming this may be due to my next problem...Being..

    Boost gauge(plumbded in via AEI unit) is Registering -10, when revved, go's to -5(so on the up ) but ive a hunch maybe my Boost pressure is simply too low to help with making the correct leaneancy of mixture...

    Would that be a right assumption??

    Carbs all good but for good measure its being opened tomorrow, and a few tweeks made to jets as per WIZARDS advice......


    As always fella's Much APPRECIATION to you

    Re: Whats this Turbo then...

    Pull the carb elbow off, start the engine, look down the venturi, and see if any fuel is dripping onto the thottle plate. Report back if so

    You'll hardly produce any boost from rev'ing the engine off-load, so nothing to worry about there.

    Right have pulled it off and its not dripping fuel, mixture screw dont make any difference when adjusted...
