mark 4 supra build

ok the 550cc injectors didnt work out the one i posted in my previous thread, getting 850cc injectors now with haltech e11v2 ecu, almunium radiator an transmission cooler an also nismo or bosch 044 pump.....have masterpower t70 turbo on it at the moment with 46mm external an sard regulator.......will i be able to crank 500rwhp with this set up.....also changing crank pully to aftermarket one coz supra ones are known to crap out an fly off

[Crimson Tears]

Why would the crank pulley 'fly off' if the bolt was torqued to specification?

naa i think they have a rubber surronding that cracks away slowly an it come off mine was cracking slowly caught it before it went

harmonic balancer, it's there for a reason, hope your aftermarket one still has the rubber bit.

better have its pretty expensive, its a ross harmonic balancer

are you buying the plug and play adapter loom for the haltech for the 2jzgte, or is that not suitable for the auto cars? will you piggyback the haltech in, or use a suprastick or similar to control auto trans?

the shop thats doin it for me said the haltech can control the transmission as well, also wat did you mean by piggy back its a stand alone ecu

[avinesh]

any ideas on what pump i should be running, has to be internal pump an should be able to support 500whp safetly, at the moment have walbro intank pump which will not cutt it i guess......already have considered bosch an nismo pumps is there any others that would be good thanks....

bosch 044 are tried and proven. i have one here for you if you want it. near new $300.
most aftermarket computers can not control the auto trans(it would add massively to development cost if the software developers had to work out how to interface with different brands and models of trans,and then replicate the fuzzy logic that determines shift patterns,stall convertor lock up,shift quality etc)so installers tend to piggy back an ECU over a factory trans,allowing the aftermarket one to control fuel and timing, and the factory one to continue to control the auto trans.
unlike the 1jzgte, the 2jzgte has no line pressure cable connected from the trans to the throttle body,which means the line pressure is controlled by the factory ECU. without this electronic control, the 2jz trans will burn out quite quickly under spirited driving.

so the 2jz doesnt have a seperate auto gear box ecu??? an piggy back you mean keep the factory ecu i heard that can hold you back a bit....an is your fuel pump intank????

[BlakeNZ]

that is correct, the 2jz does not have a separate trans ecu, so if your workshop say that the haltech can run standalone and still run your trans, please name and shame them so we can all avoid them in the future.keeping the factory ECU running the trans wont hold you back, because you have a fully programmable haltech controlling fuel and ignition. very few workshops are capable of successfully wiring in a standalone ecu over a toyota ecu that controls the auto trans.it can be done, but you have to know your stuff.
i have a walbro in tank pump. the 044 can be installed internally(usually externally though) as evidenced by justins NITRO supra in auckland, with a 044 installed in tank.

[BlakeNZ]

apparently the newly released WOLF V500 can be made plug and play with the new adapter loom that they are marketing for jza80s(also soarers too!) and has the ability to run the auto trans!!
