Building a 7age.

[Robo86]

everyone knows mine but meh


Final engine spec.
7AGE

-7AFE Bottom end - Honed, 0.5mm Oversize bores.
-Standard crank (midsized)
-Kings Main bearings
-Standard Conrods (Resized + new bolts)
-ACL Con-rod bearings
-Hypatech Smallport 4AGE Pistons 0.5mm Oversized. (new)
-Hastings Piston Rings
-New standard thickness 4AGE toyota head gasket
-Standard Bigport 4AGE Head, with some mild porting.
-New Headbolts
-4AC Flywheel
-Apexi Intake
-TRD copy extractors + 2.25 exhaust.
-Compression ratio: 11.4:1

105hp or something, chops my old BP

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

[70XIN]

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?
