The standard head includes cam caps, valves, springs, seals, retainers and keepers. To set up the cams and set clearance you must follow a procedure for measuring the valve clearances then you must buy new valve shims from Toyota or aftermarket to set the clearance properly. That can be a 1-2 week process if you have to wait for special order shims (and they’re always special order). If you select any of the camshaft/rocker options listed we will install those rockers and cams for you and shim the valves properly. We even install new lift bolts.
If you’re not having cams installed then select no rockers. If you’re going with used cams, select used rockers. If you’re having new OEM, MWR, or Piper cams installed then you can have new OEM, MWR, or Ferrea rockers installed. The MWR rockers function the same as OEM rockers but have an uprated friction pad for the big cam which reduces wear and is much more durable especially in extreme conditions. The Ferrea rockers eliminate VVL, using a roller actuated by the big lobe only, so they’re best suited to a very high revving engine with Ferrea dual valve springs and they DO require custom ECU tuning.
Select the ported head option to request a fully ported cylinder head. That includes using our builder's extensive experience on the flow bench to smooth and reshape the ports and seats for the ultimate in flow. You can expect improved power throughout the rev range whether you’re turbo or NA with no loss of street manners.
Select from a variety of valves. Aftermarket stainless valves work great for most applications. Choose MWR flat faced valves to increase your compression ratio slightly (increases stock 11.5 compression to 11.7:1). Ferrea’s valves are polished to a mirror shine. The intake valves are stainless like the MWR valves but the Ferrea exhaust valves are made of inconel which has exceptional heat resistance and is preferred for extreme turbo or nitrous applications.
Select aftermarket valve springs to safely rev 500-600rpm higher than the stock rev limiter. Add Titanium retainers for the ultimate in valve float resistance. Choose Ferrea dual valve springs and retainers for racing applications up to 10,000 rpm (may cause faster valve seat wear, not recommended for street use)
Like most engine builders we sell these engines, heads and blocks on an exchange basis. That means that we require you to send us a rebuildable “core” similar to the engine, head or block that we are sending to you. If we’re going to send the rebuilt unit to you first then we charge you a core charge, which is a deposit that we hold on to until your core is returned to us and is then refunded to you. For a full refund of your core charge the core must be returned within 30 days and must be rebuildable- this means no holes or cracks in the block, no significant damage to cylinder heads, and no missing bits such as cam caps. We don’t care about pistons or rods. Valves may be bent, crankshafts may be scuffed.
- Build time is 1-2 weeks or less with stock hardware, 2-4 weeks with upgraded pistons, valvetrain etc.
Fits all Lotus and Toyota vehicles originally equipped with a 2ZZ-GE engine.
30 day limited warranty. Does NOT apply to racing or forced induction applications. Must be installed by a certified mechanic or performance shop.
