Thread: My HC 87mm build

with 2 failed 2.4 builds behind me, its time to look forward. here's an update

the 87mm motor is finally back together, tranny bolted up and back in the car.
look for initial start-up tomorrow.

Awesome, Im literally about to put an order through for some 87mm CP's

Will the stock VET gasket work or does it need boring out?

What compression?

dp 2

bore it. i got mine bored, from MazworX.
p.s. try thmotorsports for the pistons. got mine for less than $500 shipped



87mm 12.5cr cp pistons.

here's the short list...
bc rods
acl race bearings
ve crank
de girdle
de upper/lower pans
ve oil pick-up
p&p head
arp head studs
525cc sti injectors
calum rt ecu
bc valve springs
N1 cams set @ 0/0
stock plenum/runners
de t/b
ve maf
3" cai w/aem dry flow filter
ebay header w/2.5" outlet

think thats it

after start up i'll need to take it to my local muffler shop to get the header matched up to my 3" cat back. will be running the stock oem 2.5" cat off the header.

Sounds like it may be a reliable setup Ric

Not far off my setup il be using Nissan bearings though.
370 injectors, Custom header and a 3.5" intake.

it runs! i tried uploading a video to photobucket. it took forever then gave me a FAIL. so screw it. here's a couple stills.


i put a couple ounces of marvel mystery oil into each cylinder to lube the top end till the oil pumped up. i turned the key a few times w/o the spark plugs in and with the fuel pump fuse pulled in order to pump some oil into the system w/o the engine starting (dry start+high idle=BAD). only unusual sound was the p/s pump whining as it pumped the initial fill from the reservoir.
smoke from the MMO combined with the oil burning off the new header was enough to choke the neighbors
took her for a quick spin around the block and let her run for 30 minutes. got the coolant temp up to 180 for 15 minutes .
ha, did i say NO LEAKS?
have other pressing matters so it'll be it'll be mid-month before she goes to the muffler shop then over to firestone for its 20th alignment. gotta love lifetime alignments

Nice cant wait to see how the tune goes

nice, want to see this running
