GTR Fever Posted April 17, 2012 Share Posted April 17, 2012 Hey guys, How much power can be obtained from a stock 2JZ motor? All internals stock but it has a Precision PT68 turbo, Tial 44mm wastegate, Greddy intake manifold, Q45 90mm throttle body, 550cc injectors, stock management, dual Aeromotive A1000 pumps. Engine is mated to a built automatic transmission including shift kit, valve body, clutch kits etc etc. (supposedly built to withstand 800+hp) (Optional upgrades - AEM standalone, 1100cc injectors) The reason I ask is because this setup is available from a damaged car and I'm seriously considering it..(never been dynoed, the optional upgrades were bought but never installed) Thank you in advance.

V8KILR Posted April 17, 2012 Share Posted April 17, 2012 The stock engine is safe to a maximum of 560rwhp (700hp) with the auto provided the tuning is nice and safe. I think that the turbo should make that power at around 24psi. The 550cc injectors limit engine hp to about 550hp at stock fuel pressures with more hp at higher pressures. My 2JZ-GTE fuel calculator is at http://mkiv.supras.org.nz/injectors.htm. I'd go for the bigger injectors and the AEM to make the most of the system.

GTR Fever Posted April 18, 2012 Author Share Posted April 18, 2012 thanks..what is needed for the engine itself to withstand the 800+hp? the transmission was built from MTR in Florida and it's confirmed that it can withstand over 850+hp Quote Link to comment Share on other sites More sharing options...
Ricky49 Posted April 18, 2012 Share Posted April 18, 2012 I would go with Uprated pistons, rods, rod bolts, head and main bolts, bearings, billet main cap and if your doing that do a bit of head work for good measure but not required.
