Homer Posted July 14, 2011 Share Posted July 14, 2011 Provide a full spec of the car before you go messing with the boost control. I.e. - 1st cat in place? = Removed - 2nd cat in place? = Removed - Greddy Intercooler - Apexi Boost controller avcr - Turbo timer - Which cat back system? (Copy and pasted) Supplied by Invoauto to Jabbar in Birmingham. This client waited one year for our Generation 3 Ti tanium Limited Edition back box. This is especially designed for high boost 600-1000 BHP vehicles. The pipe work was custom made to fit the G3 universal box. Has a 4 inch straight through, with 6 inch tail pipe.This is the second vehicle in UK to have this special back box and was out on display at the JAE show on 26-27 July 03. - An Invo302 full stainless steel filter was fitted onto his custom made induction kit- - Is an FCD fitted? Nope, where would it be located? but am sure I don't. - Do you have a boost gauge? Greedy Mechanical Turbo Gauge 60mm - Do you have an AFR gauge? Air fuel ratio, if so no I don't. - Which spec plugs are fitted? My uncle fitted them cant remember the make but good ones gonna get new ones what you guys recommended. If you don't check the above it could end in tears Wel you kind of screwed up the quote function, but all looks good there You need to have the FCD fitted (Fuel cut defender), it may already have one fitted if it's been decatted and has a BC, best to pull back the passenger floor carpet, remove the plastic ECU cover and see if anything is wired in. It's normally a matchbox sized black box. Take a picture in the area if you can. The plugs should be swapped as per the BPU guide. Again, pull a plug and check the code on it. An AFR gauge is highly recommended, though it only allows you to check whats going on. They're about £180 for a good one (AEM or Inovative). Mechanical boost gauges are a bit of a nightmare, some swear buy them but I hate them as most have no max hold function. If you have the money I'd recommend to swap for a good electronic one.

N-Mir Posted July 14, 2011 Author Share Posted July 14, 2011 (edited) haha I just copy and pasted it over to make it easier to reply and understand! Ill have a peek and check it out, So i ve ticked almost all the BPU mods, In terms of servicing apart from the usual stuff is there anything else that I need to replace or check like injectors? Personally I do around 2000 to 4000 miles a year max, my dad did the same and am sure thats the same for my uncle, I always use shell V-Power so am presuming they would be fine? and what about fuel pump I know supranature said to change these due to age but again is stock best for my set up or because am going to get the stock ones replaced should I pay a bit more and got something better? I did think Walbro but in the BPU section it said that the stock one was better, quieter but more expensive so what would be the next option? Thanks again Edited July 14, 2011 by N-Mir (see edit history) Quote Link to comment Share on other sites More sharing options...
Supranature Posted July 15, 2011 Share Posted July 15, 2011 Some reading for you with regards to the fuel pump http://www.supras.nl/index.php?option=com_content&task=view&id=49&Itemid=65 as I said previously you don't know what condition your existing pump is in, so best to renew anyway. The above link gives an explanation of the procedure, amongst other technical info. Quote Link to comment Share on other sites More sharing options...

Sharpie Posted July 15, 2011 Share Posted July 15, 2011 When you go bpu, the difference in power over stock will certainly make you go "wow" again, especially at 1.4 bar! Damn-Homer beat me to it With respect, and as we are in the Tech section - I don't think we want to be advising N-Mir that he should be running at 1.4bar of boost, it will end in tears! I only point this out as you have mentioned it twice in the same thread so, N-Mir (or any other noobie) might think that it's OK to up his boost on the AVCR without fully understanding the implications/risks with such a move....I didn't see him list the Apexi SAFC or the like....

Tyson Posted July 16, 2011 Share Posted July 16, 2011 I said this to a mate in the trade, he pulled autodata up and it stated on there that it was not non-interferance?? He's wrong I have read some official Toyota documents on the 2JZ and that stated it was non interference, I would trust Toyota over autodata. Must be human error when it was added.

He has a UK Spec so the safe maximum is 1.4 as supranature said, the UK's have steel turbines and can withstand higher boost. Safe maximum for JSpecs is 1.2 bar. So no tears will be shed here.

Sharpie Posted July 16, 2011 Share Posted July 16, 2011 I have seen the car a couple of times over the years so, I’m well aware it’s a UK spec I’m sorry but, I still disagree with the advice being given to N-Mir, who is new to Supra’s and is asking for basic upgrades. I think using 1.4bar of boost and Safe in the same sentence is the wrong advice to a noobie! You don’t talk about if the UK spec turbo’s are still in their efficiency range or not, what the level of reliability he should expect with running at this level of boost, EGT’s levels, AFR’s & Fuelling etc… Supranature did cover things very well in post #2, it’s the 1.4bar of boost mentioned lower in the thread that I think is crazy talk! If a noobie reads post#18 and #32 I think they could get the wrong idea and……..hence the Homer gave some sound advice, as usual Quote Link to comment Share on other sites More sharing options...
N-Mir Posted July 20, 2011 Author Share Posted July 20, 2011 Thank you for the advice guys it really does help, am away from home at the moment as you might or might not know but will update you guys on any mods that I do and the boosting set up and I respect both the figures given I'll use stock on normal driving and set up the higher boost every now and then!
