Canceled-Chris Batres is purchasing this for $1500 so I can pursue a better engine.
So the last big piece of this little Celica I’ve been wrenching on is the motor. I’ve swapped the trans, swapped the brakes, spruced up the body with better panels.
With any project the engine selection is critical, not only does it need to be unique(for me) but it has to make solid power.
My initial plan was to plop a 1mz in and build that up later but I landed a bunch of parts in the hopes I’d buy a local Alltrac but the deal fell through due to a flaky seller I had a change of heart and some of the parts I bought to use on that were rendered useless.
Among those parts were a few key components like a nice, complete gen 2 3S-GTE head, a bunch of injectors and rails with a pair of distributors, cams, two mr2 intakes, a set of rods and pistons, egr setups and a down pipe to make that alltrac smog legal.
Kinda in a transition position with the build I decided why not make use of the GTE head and the parts? Well that didn’t seem like a bad idea given I got the above parts list for $120 bucks. So what I decided to do was build a stout motor, so forged everything was a must, I figured since I was going that far I might as well get studs for both ends as well.
I figured if the same sensors are used technically I can run this motor on the same ECU and it wouldn’t know any different, this may be a very naïve thought but it’s a starting point. I have a Greddy Emanage Ultimate in case it doesn’t pan out.
So heres the list.
-Xcessive manufacturing 3sgte intake setup for a Q45 TB including an adapter for a Toyota TPS sensor.
-top feed injectors, probably going to start with the factory ones used on my 5s-fe (redone ones)
-KO Racing phenolic TVIS delete
-Gen 2 3S-GTE head, cut for 34.5/30mm valves and clearance for a big set of cams, milled 0.006”
-01 5S-FE Block (bahaha free!) decked 0.005”, bored 0.020”
-Bought a machined 5sfe crank, had it balanced, deleted balance shaft parts (91mm crank)
-ARP head studs
-ARP main studs
-beams red top cams, going to be modified for a distributor, VVT oil passage plugged. (10.2mm lift on the intake!)
-Ebay cam gears (one center custom to match the beams intake cam)
-Maxspeeding H beam rods with ARP 2000 bolts
-JE forged pistons, 0.020” overbore (87.5mm)
-Q45 82mm Throttle body
-egr block off
-Brian Crower Titanium valve spring retainers
-Brian Crower valve springs
-shim-less valve buckets
-NGK wires
-factory distributor
-Beams timing cover
-OEM Toyota 5S-FE oil pump
-Australian 4-2-1 header (or an extractor from those down under)
Things I’m still sorting is the fuel rail, I ended up picking up the wrong style Q45 TB (pretty much the same outside of the TPS mount and shaft attachment), Gen 1 3S-GE valve covers(either over the gen 2 machined to fit or standalone Gen 1’s) and a few other things that aren’t coming to mind.
The fuel rails I’ve tried; 5S-FE, gen 3 3S-GTE/3S-GE rail. I just received a gen 1 rail thanks to Joe Randall scavenging a Gen 1 GE rail from a local junkyard.
The 5s rail matched injector spacing but not on the hold down pattern, the gen 3 rail didn’t match either.
My plan with this setup is to try it NA first, the Beams cams will compliment that but I will start with gen 2 3S-GTE cams first and switch to the Beams cams later possibly with gen 3 3S-GE MT cams as an option depending on which has the most aggressive NA profile.
If the NA setup isn’t enough I’ll step up to boost, but as of right now my focus is getting it together and in the car.
UPDATE
Gen 1 rail will not work, this is the cheap alternative
http://www.mr2oc.com/showthread.php?t=213289&highlight=fuel+rail#/forumsite/20711/topics/213289?page=1There is always the speed source rail if this doesn't work.
The O rings were 10.50 shipped.
Beams cams will require a bit more machining than initially thought, but plans with continue.
(Journal is 2mm larger on the gear side, sealing method is completely different and there is not end play control based on a width of the beams cam journal vs the gen 2 head)
I will still have to make a cam gear center for it, but I will just change my design to accommodate the seal.
On a good note, the cam clearancing did allow them to clear, by a small margin but they definitely aren't drop in.
*******Update June 2016******
Switched to a beams black top head CNC ported in Malaysia.
Plans are to run ITB's, build a custom plenum for those, stainless steel top mount manifold, Borg Warner EFR (6758 is where I'll start but more research has to be done)
Plan to run the stock beams valves and retain the VVT on both cams if possible with the AEM Ecu.
****update***
December 2016
5sgte plans have been scrapped. Beams head is being saved for the triumph.
5sgte with gen 2 head will be sold to Chris for his st185.
^where it started, picked up all of this because i wanted the downpipe so i could use it on the alltrac I was hoping to buy, but due to a flaky seller that got canceled so i made use of the parts in the purchase. Cant beat 120 bucks for all of this.
^how I received the free short block
^guy said center two were down on compression so he pulled it out in exchange for another 5s
^monster 3s ports, the only reason I used the head over the 5s stuff is because at this stage I had it so why not. The alltrac I thought I was gonna get made me think spares werent a bad idea to have.
^not a bad start, had some valves come apart in its past life so it took a bit of machining to clean up the quench areas of the head
^mock up
^came with a new oil pump from a late 5s too (40 bucks haha)
^interesting composition of the later 5s pistons, curious if they would handle abuse
teardown
