1.5jz gt 42 turbo manifold.

manifolds go by flange type not turbo type.
Since a gt42 takes a t4 flange, all you need is a 1jz manifold with a t4 flange....

correct
a T4 flange is all you need, so all those 60-1 and 70-1 manifolds you are seeing will work on your turbo

GT42 will not fit, you need to move the flange forward to clear, hence a custom manifold... try to find someone that does manifold fabrications (check honda-tech for a fab guy) local to you to do some custom work.

at least in toyotas and Lexus....
well as long as the turbo dosent go higher then the top of the motor atleast not more than a inch am fine.how do i know which manifold is the right one for this turbo on ebay ? thanks guys.
i test fitted my borg warner s474 which is comparable in size to a gt42 on my drewgo manifold on my 1jz engine in an mk3 and it fit fine. Just had to clock the compressor housing so that the outlet faced downwards.

yeah, actually one of my customer has a gt45 with a 1.06 T4 back.... a.k.a. Donky turbo.
His issue is the height.

how did you do your ic piping? mine is pretty tight and i'm having some issuses

i ran my piping at the bottom where the bottom radiator hose is. It's a shorter distance from the turbo to the intercooler with less bends as well. All i had to do was weld on a 3 inch 90*elbow to the comp cover. Less piping less lag.

And that's on a 1JZ right? A 1.5JZ is going to be worse.
How much bigger is the GT42's compressor housing over the GT40? I have an HKS long runner manifold that sits the turbo pretty low:
That's a 4" inlet pipe on the cold side, to get an idea of the size of the turbo. The 1JZ is pictured, the turbo WILL clear the strut tower bar I have there, I just didn't install it. With the 1.5JZ, it interfered with the strut tower bar, but still clears the hood no problem. A GT42 shouldn't be that much larger in size. It should fit no problem....... assuming you can find an HKS manifold that doesn't cost you an arm and a leg.
If I can find a good 2JZ manifold for a good price, I might be swayed to sell this manifold, and swap my head over

alright i'll give it a shot but it looks pretty tight down there. you think you could get me some pics?

going down to the shop sometime this weekend if i have time. i'll try to take some pics.

I did something similar. I haven't welded onto the turbo yet though, just have a coupling there, going to a 90 on the pipe.
