Hi all, its been a while since i have posted on this forum (have been busy building a house and becoming a dad so had little time to spend on the v8 supra). After a couple of successful show seasons here in the UK with the 1UZ Mkiv Supra i had decided to take it off the road one last time in...

Hi all. as part of my single turbo build on the V8 supra I thought I would re use an old oil filter relocation kit I had on it when it was a straight 6. I was wondering is it a must to run an oil cooler on a trubo v8. the turbo is oil cooled only so my gut instint is yes. If so I have a spare...

Hi all, Now I know this has probably been asked a billion and 1 times but I was reading on another lexus site about a budget low boost single turbo set up and im a tad confused. from reading it it would appear that only one header is being swapped to be facing the opposite way so in theory the...

Hi all, probably a really stupid question but unsure what they are etc. firstly the one circled in red, what is it and can it be removed on standard management if i made a blank. already removed power steering if its anything to do with that. secondly the one circled blue what is it and why...

Hi guys, i bought my first v8 soarer last night to do the conversion on my mkiv supra. it had to be towed home as it had no mot or tax on it. when i got near my home i thought i would give it a try and start it up. it has a fully charged battery on it and jerry can of fuel. now tick over it...

Hi all. was sat here today thinking why am i going to spend out more on buying twin turbos and not just get a single. then this sparked off another thought. v8's obviously have exhaust coming out both sides. so do you bolt up the turbo to one side only or do you do it to both. help my head now...
