Building a 7age.

[n2866]

I pretty sure you won't get much more hp but the torque is great. But I think mat(pen15) car made close to 90kw on the 4age bottom end. And also when doing the said 1zz crank it tips it over a 2l.

[Robo86]

yer mine pulls so much harder than 4age and cost me so little

[Sprinter86]

im not sure mine belongs in this thread lol...


-7AFE Block
-7AFE rods
-7AFE pistons
-7AFE oil pump
-7AFE Sump
-4AC Head
-Regrind Cam (270)
-4AGEOil Cooler
-WEBER 32/36

Makes 60kw atw with more torque than any of my 4age's. would easy make more power with 4ac style pistons and more comp.

Thats awesome!!! I rate it!!! Ive always thought if my 3tc shits itself in my ksev once i get around to it, id throw a 7ac together and see how that went lol

[Sprinter86]

if you do end up doing it, remember that the key part to the 7ac is a Mitsubishi colt timing belt

I have a question aswell, im just gathering parts for 7agte setup, using a blacktop head, i already have a brand new 7A oil pump, will this be sufficient compared to say, a blacktop oil pump?
what differences are there, just volume?

any help would be great

the thread is building a 7age but you get an A+ for effort i cant imagine why you would build a 7ac unless you had a magneto coil and mechanical injection but still a very cool engine what timing belt/chain did you use and things

Okay mine is kinda basic, not quite as crazy as delazy's monster. Should be fun though!

block - 7afe stock
crank - 7afe stock
crank timing gear/sprocket - bazda modified (offset keyway)
flywheel - J-Works 4kg chromoly flywheel
bearings - kings
conrods - J-Works H-Beam
pistons - ae111 4age stock
oil pump - 4age 16V + 4age 16V tensioner
headgasket - stock ae111
head - ae111 20v slightly ported
cams - TODA-R 264, 9mm
cam gears - ae111 4age stock
timing belt - 4age 16v stock
intake - ae111 itbs/70mm J-Wworks stacks
extractors - RSR, soon to have J-Works 'Octopus' headers
cooling system - Garage Annex
ecu - ae111 4age stock, with Garage Annex modifications (unknown. could just be speed de-limiter)
fueling- ae111 4age stock, TOM's or stock ae111 4age FPR depending on what the wideband says
miscellaneous - ARP head studs and ARP bolts

I hope to make 120-130rwhp. My <2" exhaust from headers to cat will be quite restrictive though.

on my boss's 20v stroker 7a he uses a stock 20v timing gear on the crank and then uses a Peugeot timing belt how come you guys dont do the same?

[fantapants]

does he use cam gears? if he is using adjustable cam gears and disabling vvt then he can dial the timing differences out with those, but if he is using the vvt timing pulley, then the simplest way to reset the timing to the correct place is to recut the timing keyway...
