How good is a std mx83 Cressida radiator?

[Cressid@]

Hey all,

Just a quick one as I've searched and can't seem to find the answer. How much power would my 1jz need to pull before I should think upgrading my radiator? To add I'm using a 2jz water pump, new clutch fan unit and mx83 blades. The new clutch fan unit is amazing pulls so much air through.

Your thoughts would be most appreciated


Thank you

Standard will be fine, although being a 20yr old radiator dont be surprised when it fails - when it does, use one of the chunky full alloy China spec replacements.

I actually saw those china alloy ones but because I'm using a clutch fan setup with the mx83 shroud so I'm quite tight for space.

Anyone out there with the same setup that can shed some light?

not exact same, but yes - if the rad is in good condition, it'll be fine. If it's got 50% bent fins and is only flowing 40% of what it did new, you'll need a new one - measure what space you have to work with, and put in an alloy one that fits. You could either take your rad to a specialist to get it tested, or just put it in and see what happens, and replace when/if necessary. Depends if you want to do it all perfectly first time, or don't mind messing around a bit further down the road

Thanks for your input guys. I guess the reason why I'm asking is i need to buy a new radiator. I have a gt30 single setup on my 1jz so power has increased and If a new std mx83 radiator is sufficient then great I'll just stick to that.

I had a bigger radiator in there before but the fan blades tore it to shreds due to the limited amount of space when the engine rocked.
