My new build and some ?'s
Posted: Tue Jun 19, 2012 9:39 pm
Here I go, first post on the forum. Thanks in advance for the help. I have been running a 1mz in my MR2 Biohazard race car for the last two years. It is so much fun I decided to use it in an upcoming build for a kit car, but I have a few questions on which direction to go.
3.3L Twin Turbo with about 15-18psi. I am thinking it should have about 450-550 hp at the crank depending on rpm limit. So I have a few items that I am having trouble figuring out and could use help on.
1- What pistons to use and where to get them. I am thinking 8.5-9.0 c/r. I was going to call Wiseco and see what they have.
2- Head gasket? I was thinking of getting Cometic to make a custom one if they do not already have one, but any other suggestions.
3-Valve springs- Who makes upgraded ones or how to get more rpms out of the engine with boost and higher revs
4-Shimless buckets? I have done this on the 3sgte, but I reved that to 10,500. Is there a toyota drop in or does the 1zz shimless work?
5-Best way to raise rev limit. I have used oscilator chips to overclock the camry ecu and that works but might not be great at higher rpms. Is there another way?
6-Emanage- Does anyone have a base setup for this? I have tuned with TEC3 so I am wondering how hard it is to get the emanage up and running? I will have a wideband and will be able to datalog with that, but I am not sure of the capabilites of the emanage unit. It seems that most higher hp cars use it so it must work, just wondering how easy the setup is.
7-Am I missing anything major from the list below?
Thanks for the help and tips. Thoughts on my future setup?
Here are the specs
3mz block and head, stock 3mz intake and exh cams with vvti disconnected
8.5-9.0 c/r (which pistons should I get that work in this block with the c/r I would like)
Ported polished head, might as well clean it up a bit while it is out
Valve springs? (which springs to get? I want to rev to like 7500-8000)
Longitudinal mounted engine
G50 transaxle with flywheel,clutch,pressure plate and bearing supplied
Twin turbos, not sure on which yet, Maybe T28, GT? or t304b with .48ar housing. They should flow about 30cfm and spool fast. Twin turbo fun.
Dual 2.5" exhuast with borla mufflers
Dual 1.5" wastgate exhaust
Custom exh manifolds
Dual 38mm wastegates
Twin MR2 air to air intercoolers
Custom intake manifold with med to short runners and velocity stacks for mid to higher rpm
Head gasket? cometic custom with the rings in it to seal well? Anything else for the 3mz block that works good?
75mm throttle body to match intake and take in all the air
600 to 680cc injectors
Greddy emanage
Boost controler- not sure yet, maybe just wastegate spring
Custom oil pan or modified stock oil pan for longitudinal engine mounting
accusump
oil cooler or coolers. Might just use two small ones right before each turbo
Bosch 044 fuel pump to feed the rails and surge tank
Aeromotive FPR
All an fittings and SS lines.
Zentronics wideband and datalogger with rpm, afr and boost
