G'day Mud team,
After researching exhaust manifolds for some time when turbo'ing my HZJ78R earlier this year, I found the 1HDT and 1HDFT manifolds flow no better than the stock 1HZ manifold. This got me thinking.. lots of guys don't really need to buy new manifolds when doing CT26 installs on their 1HZ's - what if I could make an adaptor plate?
So I drew up an adaptor plate on Autocad, had it laser cut, then tapped/countersunk required holes and then mounted it beneath my 1HZ manifold. I then installed a 1HDFT take-off turbo (Toyota CT26), along with the other required goodies, and she works a treat. Pushing 16-17 psi through the 1HZ now, absolutely changed the car. Runs nice and cool with plenty of boost, lots of power, perfect!
I'm now selling the plates as a kit in Aus ($170 AUD in postage).
If any international guys are interested, have a squiz on Facebook, at Simpson Off Road Engineering, or shoot me a message on here.
Cheers!
