Building a 7age.

[70XIN]

Yeah that compression would be fine. I seem to remember Robo's is up around that number, he just had to run 7 degrees of base timing instead of 10 .. unless you plan on cams.. which would be awesome.

Cams later.

Want stock ecu. And like 27x cams

Oversize Toyota pistons fine?

Worth balancing crank and running lighter harmonic balancer? Like about would like to go 27x cams later. stock ecu..

im not 100% but im pretty sure youd just foul plugs and it would run like balls.

only if the limiter gets sat on alot as in drifting but as for racing i think it would be fine and as for the compression i think the more comp the better allows for upgrading the head later and the more comp you have the more efficient the engine will run there is power to be made just in upping the comp lok at smallport compared to bigport 86kw at fly to 100kw at fly cams are the same duration only major difference is the comp, intake ports and ecu

[Robo86]

you wont sit on the limiter with a 7a, at least a basic one (stock ecu/cams). there isnt much up top! goes hard through the mid-top though

Cam's would give it more power up top, so I would be up there more I think.

People post up their setups!

block - 7afe
crank - 7age nitrated
crank timing gear/sprocket - bazda modified 16v/ae101 20v
harmonic balancer - ross tuffbond race series (yet to be made, eta july)
flywheel - toda 4.4kg
bearings - acl race series
conrods - belfab racing 7afe
pistons - custom wiseco (unknown specs, special order by engine builder)
oil pump - ae101 20v + ae101 20v tensioner
sump - ae101 sump/ae101 windage tray/tecarts spacer plate + accusump
oil cooler - greddy thermostatic
headgasket - stock thickness cometic
head - ae111 20v (smoothed ports)
valves - supertech 1mm oversized
vale springs - supertech heavy duty + ti retainers
cams - kelford 288/10mm
cam gears - toda
timing belt - toda 16v
intake - ae111 itbs/30mm sptech stacks/nobybooth airbox
extractors - powercraft 4-1 n2
cooling system - rschita conversion with genuine 16v waterpump
radiator - koyo
ecu - haltech ps1000
miscellaneous - ARP head/mains/flywheel bolts

final CR - estimated somewhere between 11.5:1 and 12:1 from memory....been awhile since we worked it out....
power/torque - unknown

first attempt starting - ETA 12-18 months lol

abit of a puzzle/collection of bits and pieces...i honestly dont know what to expect from it...could be 100kw could be 120-130rwkw...quite excited to see how seamus goes with his motor...

7a block .5mm oversize
7a crank stock size
spool con rods
wiseco pistons comp ratio is 12.37-1
7a stock brand new Toyota genuine oil pump
7a sump
4age 16v stock head gasket Toyota genuine
4age 16v bigport head ported to the shit
264 hks cam shafts at 8.1mm lift on intake and 8.35mm lift on exhaust
toda single valve springs
fidanza adjustable cam gears
Porsche timing belt
t3 quad throttlebody adapters
ae101 silvertop individual throttle body's
stock 2nd hand head bolts
stock 2nd hand main cap bolts
arp 2000 rod bolts (comes stock with spool)
and just Toyota genuine seal throughout

that's my setup there is nothing to over the top for the moment but my new head will flow a few more horses with all the wright mods a 7a will make power up high im thinking of also building a 7a 1zz crank for a nice 2L setup

[marvis]

^ what sorta power is that?

[Robo86]

everyone knows mine but meh
