I emailed them , they said they could make them if I orderd 30
-
its hard to say without seeing it . but dosent sound good. its hardly a common fault for jz oil pumps to fail
-
where was this?
-
believe it or not. the new range of nankangs are pretty tasty. a world away from the old stuff
-
any explanation why? bore wash? so they buggerd it up? did the oil pump fail , why would it have oil starvation. im not happy with this

what about this? too restrictive ? •Inlet/outlet 4"/2.5" •Features wet float bearings •1/8 NPT oil inlet •3" V-Band downpipe flange •Compressor wheel: .70A/R, Inducer: 91.00mm, Exducer 69.20mm •Turbine wheel: .68A/R, Inducer: 74.00mm, Exducer: 64.10mm - - - Updated - - - what about this? too restrictive ? •Inlet/outlet 4"/2.5" •Features wet float bearings •1/8 NPT oil inlet •3" V-Band downpipe flange •Compressor wheel: .70A/R, Inducer: 91.00mm, Exducer 69.20mm •Turbine wheel: .68A/R, Inducer: 74.00mm, Exducer: 64.10mm

So what. Full spec should i bee looking for . Ie turbine size trim ect
-
would this be too big/ laqggy Inlet Size 4” Outlet Size 2.5” Type of Flange T4 Flange Type of Down Pipe Flange 3" V band Type of Cooling Oil Cool only Compressor Trim .80ar Compressor Wheel Inducer Dia.: 76.71 mm Exducer Dia.: 102.36 mm Turbine Trim .81ar Turbine Wheel Inducer Dia.: 64.5 mm Exducer Dia.: 74.5 mm Applications T4 turbo charger

in my case undevided
-
just to jump in here, are we saying .81 ar for hot or cold side ? and if it is a .81 hot side what cold side trim suits for best of both spool time/ power
-
slight over kill then, so a t70 with .68 and .70 will enough for 550 on 9.5-1 compression. with a stand alone. the only reason I was thinking bigger was for lower egts and less stress. all this turbo sizing gets confusing as hell, im looking at all sorts and my brain is melting. I mean, whats the advantage of a bigger a/r hot side than cold side and vice versa.
-
thanks noz. what trim do you think
-
I messaged cx racing and they were as helpful as a lube at a lesbo convention so ill be giving that a miss
-
im not bothered about actual numbers per say I just want the best balance of response / punch without tones of lag but I don't want to be maxing out components
-
this on on an na-t with 9.5-1 not the tts 8.5-1. 1bar with 550cc injectors made 510bhp with a piggyback, @44psi of rail pressure so I can make more power with less boost so the 630s should be capeable of 600+ on the latest set up
-
ok a brief setup overview. 4 speed auto with a01b stand alone ecu 635cc injectors 9.5-1 compression ratio. my question is what size turbo, it will be a generic journal baring turbo as per usual but what size a t61 .68 .70 ? ive used before and had over 500bhp but was maxed or a t76 .80 .81 im guessing it will make more power without being maxed bit at what lag cost input always appreciated
-
and willit foul the steering column
-
ive seen these , they look good but will it fit rhd ??? - - - Updated - - - do you have a link?
-
no if a log will give me high egt's over 500bhp ill stay with a tubular but a diferent one - - - Updated - - - no if a log will give me high egt's over 500bhp ill stay with a tubular but a diferent one
-
ill be going 9.5,1 id like to see more than 500 - - - Updated - - - in that case a tubular will be fine as long as it clears the dizzy and sits the turbo a bit lower
-
its height aswell the bigger hot side impeads the tb , plus I ideally want the faster spool of a cast/ log type
-
How much of a difference did changing your intercooler make?
dr_jekyll replied to a topic in Supra Chat
I changed from a fmic to an oem smic and the only difference I noticed was the side mound saved me about 3-400 rpm of spool time . ( this was an na-t so I cut out over a meter of ic pipe too ) -
whats about manifold wise for an na-t these days . I would use the xs one ive always used but I may want a bigger turbo and I don't really want to have to use the 4 runner dizzy this time so im hoping for something I can for a 76mm on with the oem dizzy in place and use a the 4" intake . so the question is . what is available that works on a rhd car that wont break the bank?

cheers

yea pretty sure its in the workshop somewhere. ill have a look tomorrow
