I recently rebuilt a 1.5JZ from scratch, plus redid my radiator support and cooling setup while I was at it.
Goal was a conservative reliable drifting setup, over 400hp/400tq, and fast spool. Absolutely nailed it.
- Non-VVTI 2JZGE block, crank, & rods
- 2JZGTE pistons & head gasket
- Non-VVTI 1JZGTE head w/ modded oil port to better align/seal with 2J block
- China DBB GTX3076R copy w/ T3 .82AR exh housing
- China T3 exh manifold
- 44mm Tial MVR
- 800cc DeatschWerks injectors
- AEM V1 ECU
- Chasebays harness
At 17psi, made 423hp/471tq
At 20psi, hit the 450/500 ballpark
Full boost by 3300rpm... Snappy!
Northern radiator with monster 3-3/8" thick core compared to Mishi SR radiator.
Modified the radiator to make it a dual pass (welded up by the one and only silviaks2nr). Also modified the upper water neck with a filler and a 90 to the passenger side.
Cut out the old lower rad support, welded in a new rad support further forward.
Fan to belt clearance. Ignore the harness, it ends up down low on the shroud with plenty of belt clearance as well.
All buttoned up. Still need to make some shrouding to better direct air flow thru the radiator.
On the rollers.
