oh fun,

to bad it's not a 16v I have a complete uncut harness and ecu out of a 91 usdm ae92 I would make you a sweet deal on.

The blacktop will be fun, it seems like the 4a gets a bad rap here because the 3s is such a great motor but they are dependable,
smooth, and a lot of fun to drive.

That and the 4a's dont have much torque. Makes more sense in a light car like the corollas. Most users say they wasted there time swaping a 7a for a 4a unless they build them.

yes, and the rolla/ hatchi guys lol "upgrade" to the 7a.. the builds that i have seen that seem to be the most successful are the 7agTe' s in the old 86.. they will swap the 7a's bottom end in place of the 4a... and also IIRC i remember seeing that the 16valve makes more power than the 20 valve when boosted..

my brother was in the area during the time i was porting my head (just gasket matched and some smoothing of the runners and getting rid of the machining/casting imperfections) and is of the opinion that the 7a head could actually make a good bit more power and flow allot more than what most ppl give it credit for.. he said that there is ALLOT of metal that can be removed from the head, both on the intake and exhaust.. and that NA gains could be realized w/ some time on a flow bench (to get measured results) and over sized valves (which can be had for cheap from the 4age/gze head) but the best results would come from a turbo application.. i have 2 spare heads and he will be building my next(full boost) application motor.. and i am curious on how much of an improvement he can get on the flow of the head, but that will be a wile from now as he is still looking for a flow bench that will work for what he wants and for the right $$$

any hoo, rambaling over. .i hope all goes well with your build, what ever the direction you deiced to go ultimately.. IMO stick the the black top, its already in there.. see what you can get out of it!

i will agree that there is alot of metal to remove, building an na 7a right now. hopefully i get some good numbers and open up more people to modifying them. not gunna do oversized vlaves tho, 3 angle, port, polish exhaust ports, cams, 11:1 comp. forged bottom end. We'll see what we can squeeze outa her

what are you going to use for a controler? MS3, trust E-manage ultamate, safc, or any of the full top $$ stand alone???

Not sure yet. Gunna be a while to get everything together. Money is an issue. Lets not hijack this thread. Comment on mine (7a n/a build)

Attached the rear motor mount today



Anyone know what this is? Found it next to the starter wear the big power cable runs.




And shipping my harness to DRTWEAK tommrow to get this thing running hopefully in time for the celica meet at starved rock, Fingers crossed!



OO and got some free steelies, also need brake pads it was metal on metal -.-




^^THUG LIFE!!!

Signal wire? Look around on the starter. Should plug in around there.

I unplugged it from the starter the wire was cut from it, would this prevent the starter from getting power?

Could be

the black wire that you are holding in your hands, was that pluged into the starter just next to the BIG wire that is bolted to the starter? if so then yes, your car will not start with out that wire.. it is the signal/switched wire that tells the starter to turn over, the BIG wire only feeds power to the electric motor in the starter.. so you need both.. hope this helps

looks like i will be playing with the harness one last time before i go to work to see if that was the problem thanks!

Hope thats the only problem. Tired of reading this and only seeing problems being sorted out. I wanna see a post about how much you love 6gc's and how the 4a feels!

yup.. np. but you will have to get a new O2 sensor as well.. looking in that pic the sensor is there, but the wires are clipped off... you will get a CEL due to that.. cahlk one more to the list.. but easy fix though

Yes, you will need that wire on the starter. I'd check all the wires on all the sensors before shipping the harness out, a quick tug to see if the wires are cut/loose should do. If this wire was making a very loose connection, then that explains why the car would sometimes start but often wouldn't.

I'm dying to hear a review of a 4A swapped Celica. I've found a select few posts saying the Silvertop swap is a poor choice for a Celica due to the car's weight and the engine's low torque. But I don't believe I've read anything on a Blacktop swapped Celica so I'm hoping you can get the wiring sorted out and have a reliable DD. I'd love to see this thing at the Midwest Meet.

Yea i saw the 02 a day after i got the car, DRIVER gave me a 02 he had laying around from his car, and old warn 02 is better then no 02 imo

And this list keeps getting bigger and bigger lol


The wiring harness has bin out of the car for about a month, i will ship it out anyway and have drtweak work his magic and fix what needs to be fixed, and i hope it will be a reliable DD and i extreamly hope i will be there at the midwest meet, if not i will bring my broke ass miata

Went on a quest today to pick and pull in Indiana



Found some fun...





Learned that hatch tails do not fit coupe's




Sat in a manual celica




I must say i loved the way it felt and that will be on my to do list for spring 2013

found this baby



Anddd then this baby




And this cutie



I loveeee the way it looks white and i have a feeling mine will be white in the spring also


Got this for my hooptie



Pedal assembly with a throttle cable, relay covers relay box and other small crap i pocketed

Andd tinted my side markers



Waiting for Drtweak to update me on the harness

Glad to see you decided to keep her. I hope you get it where you want it soon.

wow! so many of them at the junkers. I can never find a single one by me.

only 3 and a half hours away from you
