This means at operating temp the rod will be longer and closer to the head. On a performance build I highly recommend measuring the actual deck clearance on your motor. I removed the sandwich plate behind the oil filter because it is easier to access than the oil line (to the oil cooler) and is the same as the one on 7AFE wrap in a plastic bag and check the seal has not fallen off the back. You may have to register before you can post: click the register link above to proceed. Tighter than that and you could risk the piston hitting the head. We can also get 20v pistons made with modified specs and are now working on improving the 20v shelf designs. Fit the oil cooler sandwich plate which you wrapped in plastic and a new oil filter The project started when I wanted a way to find more torque from the 4age engine. Using quality parts is the key to an engine which not only makes big power but is reliable. Another place that most piston manufacturers mess up is with the dome volume.

Bolt on your new 212mm clutch (a nice little upgrade) (19nm), On to the left hand side Change injectors take care not to damage the fragile seals, in fact you should replace upper and lower seals as they are probably very worn out! Including a Blacktop specific piston which to the best of my knowledge is the first production BT specfic design anyone has offered. For your average build or for pre build rough calculations this number can be used. It is very important to pay attention to the compression height on aftermarket pistons because most of them are a good bit off. This post is created for those who wish to modify their CAMPRO from mild to extreme machine. This brings the piston back flush with the deck. We have made improvements to our designs since the development we did with Arias and also offer a lot more options and variations.

= 54.4728, swept volume = cross sectional area of bore x stroke – dish in piston Valentines day 2017: love for the hachi-roku! ), Experience a 4age with a killer torque band, the rear tyres have no chance!!! The pipe support bracket on the side of the engine block cannot be used I just left it as it seemed secure enough you could make a simple bracket to hold it.

The big advantage is more torque throughout the rpm band. = pi 8.1 ^2 /4 x 8.55 – 12.5562 Use the adjustment on the cam pulleys to retard each camshaft by approximately 3-4 degrees to so it all lines up nicely, The middle timing belt cover will no longer fit, On to the back of the engine use correct tightening pattern first all to 29nm then each through a further 90 degrees then all again through a further 90dgrees, see manual through the throttles and i cnt seem to get the timing right. Home / 4AGE / Car Stuffs / Toyota / 4AGE 20V to 7AGE 20V conversion. It is good to have a manual with you for torque settings and detailed information on the individual jobs you will undertake. Deck clearance A stock piston would be 0 but for the arias we must take 30.5 -30.226 which is the 1.190 in converted to mm. Check which holes are used by looking at the 4AGE block: This post is created for those who wish to modify their 4G13 and 4G15 from mild to extreme machine. MRP 7age engine internal conversion kit. = [ pi 8.1 ^2 / 4 x 0.0266 ] + [ pi 8.1 ^2 / 4 x 0.03 ] + [ 39 ] +[ pi 7.3 ^2 / 4 x 0.3 ] I do believe that from the factory many 4AGE blocks come on the tall side of nominal meaning the piston still sits slightly below deck. = 428.025 + 54.4728 / 54.4728 Work methodically around the engine removing bolts and wires, label anything you don’t know or may confuse you if you forget. This process is fairly elementary in nature… There are few differences in peripheral components depending on the engine orientation and the chassis it’s installed in, but all of the components should be readily available from one of the 2 engines you should have on hand the 7A-FE and the 4A-GE. For most of us in the world of light to moderate builds .75mm to 1mm is a great and safe target. A tab must be cut off the Celica injectors try one on a injector plug and you will see which tab needs cutting use a sharp knife then the plug will fit like normal, Stage 3 – return engine The Toyota Corolla AE86 winning the 1987 BTCC driven by 2017 BTCC winner Tom Ingram!
Most applications use similar ECU and peripherals from the 4A-GE and seem to work quite well despite it’s increase in displacement. Well, the “FE” design head is a twin cam but is driven by the crank only on one cam.

You can use this compression ratio calculator to crunch numbers. Stage 2 – building 7AGE
