looks good mate! im in the middle of doing mine (j spec ) i see your in the uk same as me im from newcastle. what psi you going to be running the turbo (on stock internals) if you have 380-400bhp? and with it being RHD did you remove the enginge to drill the oil pan? also im getting rayn from 2bar tuning to map my greedy ultamate well recomended

[dr_jekyll]

the car has been turbos for a while. ryan is superb mate , he dose wonders with the mapping. mine made 381 bhp on 95ron @6psi . ryan has mapped it for what he estimates will be about 400 hp @ 9psi on 99ron, the reason being was that i couldnt get any 99 on the day it went to be mapped ( 5 am on a sunday morning )

the timeing is set at 6btdc to avaoid det at 9psi as its pushing the limits on high compression, i could lower the compression but for sprinting the high comp / low boost is perfect with a verry sharp responsive throttle

to drill the oil pan i removed the drivers side engine mount and jacked the engine up to tilt it over , then used a 90 deg hand held drill with a cone cutter . flushed it through a few times then changed the filter , sorted. :)

yeah i got a 90degree drill bit like. how does the car idle at 6btdc? im going to be runing stock internals and HG but 7psi of boost and factory timing. what power should i expect from this? cheers

here is the link to my build http://forum.clubna-t.com/showthread.php?t=11104

[dr_jekyll]

the car idles perfect, tbh off boost its fine at 6btdc . if ryans mapping it depending on supporting mods at 7 psi i would expext too see 370+ but im pretty sure he will pull some timeing , he will probably set it up the same as mine using my map as a base . youl be verry happy and supprised mate,

7 psi of posotive pressure on a high compresstion engine makes a huge diff, itl go like a rockett

[TOTAL TINTING]

class mate! i just connected the ignition timing wire the outher day like. so thats a good thing if he needs to mess with that. i was only expecting around 280bhp so any more than that then im a very happy man! and if it hits 370bhp im a very EXCITED MAN! ;-) lol.

also i have the AEM TRU BOOST its the boost gauge and electric boost controller all in one. and i have fitted a 5.25psi wastegate spring (red spring). now i cant put my foot down to play with the boost controller to make sure 7psi is my limmit with out a tune! so will ryan do that? how did you set your psi or did ryan do yours? cheers

[TOTAL TINTING]

just spoke to ryan he is going to set the AEM TRU BOOST up for me and also is going to drive up to me in newcastle ;-)

[dr_jekyll]

you wont want to run on boost atall utill the map is set to up the duty cucle on your fuel or youl go lean and melt pistons :)

my boost is set with a manual boost valve on a 6 psi spring.

if you give the car to 2 bar tuning with all the parts fitted , he will give you back a masterpice, he will fully map the car, this includes boost levels , fueling , injector dutycycle, and timeing. it will supass 270hp with ease. ill see if i can find one of my dyno print to post for you

[dr_jekyll]

here is a graph from when the car was running at 0.45bar about 6psi i think

i cant wait now !!!!!!! lol. that pic is not showing for some reason?

[TOTAL TINTING]

hi mate ive just installed my kit. what did yours idle like before it was mapped ? just because mine is running verry lumpy thats all. im running stock everything and only drove it 15mins and kepet it under 2500rpm. any ideas mate i thought it mite be the 4runner as thats the only thing ive changed . thanks

[TOTAL TINTING]

also whhat sparck plugs did you use (code number if possable) are they turbo plugs, colder plugs,or copper plated. cheers

[Mr Ree NZ]

Just a thought mate, are you positive you have the HT leads wired correctly? Its quite easy to get wrong if you arent paying it 100% attention.

Is it possible you have one back to front and thats causing the car to burble and miss etc??

[dr_jekyll]

i used ngk irriduim plugs, ill look at the box for the number . double check the leads on the 4 runner cap as its easy to get one wrong. also have you removed the inlet, check all vacume pies and make sure the map sensor is plumbed in. what ecu have you used? check all your wireing and conections are sound.

yeah ive checked and checked and checked once again! i even put my factory cap back on to see if it would make any diffence but just stayed the same! if i power up on the throttle untill i here the turbo start to whistle and quickly let stright off it will go back to normal and be ok ?

i think it must just need mapping! and i think because its an auto i cant keep it in lower gears to try and keep pressure down. like for example in my corsa turbo i had. if i give it full throttle in 1st it wouldnt boost much but in 2nd and 3rd it would start to boost at the lower revs and in 4th and 5th it would start to boost at a blip of the throttle. i could be wrong like but i cant think of anything else. and ive just been told on my HELP! thred, that even tho im not boosting it , it will still be forcing more air into the intake than normmal and upsetting the factory ecu and that could be the problem? im clueless at this point but i think hes rite?

hi mate i didnt touch the inlet manifold and ive checked all connections over and over again! im just running off the factory ecu at the moment. and my greddy ultamate is ready to be fitted im just waiting for rayan as he wants me to drive 2hrs down to him but the car wouldnt get me there. so im trying to get him to come up and map it on the road or even a base map just so its drivable then i will take it down to him if need be. well if thats the problem.

how did yours drive before you mapped it? thanks

[dr_jekyll]

mine idled pefectly before it was mapped. it should idle any differently as the part of the map wont be changed from factory

just a thaught, try adjusting the timeing on the dizzy . crack off the 12mm nut and slowly rotate it , see if that improves it. my timeing isretarded to 5dbtdc to lessen the chance of det on boost but drives and idles fine on that

Yeah I can get mine to idle fine now as long as I reset the ecu and don't drive it. But if I drive it , it must do somthing to the ecu? Or summit. Could you drive yours before you got it mapped? It's just rayn wants me to drive to Leeds to get it mapped but I can't even really get 5 mins up the road before it goes funny.

[dr_jekyll]

thats a bit strang mate. best bet would be to traler it to ryan and heel sort it, no issues

did you use the factory o2 sensors (lambda)?


i had to change mine for the bosh threded type as thats what was fitted to the down pipe so my factory ones wouldnt fit. just in case thats whats causing me the problems.

cheers

[dr_jekyll]

i also have the bosch type sensors. works fine for me

[dr_jekyll]

hey guys , sorry for lack of updates , ive been a busy boy :) round 1 has been and gone and we made some good progress with the car. we fitted the meister r suspension a few days before the round and its is superb , as we adjusted the set up through the day we found a few seconds of laptime. also verry impressed with the competition stage 4 clutch , verry good.

here are a few pics from the day enjoy, ours is the blue tsc supra :)

Lovely looking supra and conversion :) I take it you know Dr Paul with his auto N/a supe in the sprint series? He used to run an Aygo...
