6G Celicas Forums

i have a 1.8L and im not looking to make a swap. i want so bad to show that this little beast has power i plan a lot of do it my self modifications (worked as a machinist for a little while ) any ideas to get me started? if u look at my profile you'll see the little i all ready have.

Its really hard to get power out of the 7AFE, especially with regular bolt ons. For decent power, a turbo will be needed. You can get the basic I/E/H which you have 1.5/3. Custom 2.25-2.5 exhaust piping. aftermarket header, and a cold air intake.. that should give you some umph.. also adjust your timing some and use a higher octane.

im planing to fabricate a cold air intake friday i was going to run it in front of the fans is that a good spot? in your opinion

Try to locate near the fender, having it near the fan/radiator may not be best area for them.

4age 20v swap is a good option don't spend money on 7afe...

If you really will not budge on a swap you can get a air fuel controller FunkySR got one and he's at 118hp now with minor mods

I completely agree

How much Is the 4age 20V? Is that what coomer has In the yellow Celica?

Yes, coomer's Celica had a 4age 20Valve, a silvertop to be more specific. They are found in the Levin GTZ Corolla. 160hp but on dyno it brings out about 120whp. another member has it in their Celica, Xpander.

130whp thank you very much!

So how much Is the 4age? 4 G's?

maybe if a shop did everything for you...

Silvertop is ~1K for EVERYTHING
It bolts right in to the ST, so if you can bum a cherry picker from someone you should be able to do the transplant yourself.
Make the harness yourself, or send it off to Dr_Tweak and have it done for ~400
So for ~1500 you would have it in the car and running... this is in the best case. You'll want to change the timing belt while the motor is out and other preventative maintanence...

Other than that, you'll need a paseo throttle cable and other various things along the way, and if you plan to modify it with a lightweight flywheel, new clutch (which you should do anyways) and exhaust

I would set aside about 2.5K for the 20V swap if you plan to do it yourself... 4K+ if a shop is going to do it....

For what it's worth it is a fun little motor

you can find the 4age 20v SilverTop for 800w/o tranny and 1100 w/ manual... 500 or so for extra parts, 400 for harness, rebuilding it will run ya about 400
this is one of my things on my to do list...

Thanks, I think I'll put this on my to do list as well. You guys are awesome.

meh, for that kind of cash, i would just do the normal I,E, a couple degrees of timing advance, and throw in some cams
i would bet that would net you ~125-130whp, which out of a n/a 7a, wouldnt be bad at all, and would make the 7a feel much more "alive"
cheaper, and less hassle.

not if you are burning oil... thats the last thing you want to do

thanks man kinda got off topic what kind of cams and how much timing advance

i dont see the op saying he has an oil burning problem?

webcams, and or colt cams can grind a set of cams for you.

as long as you use premium fuel, a couple degrees (2-3) of advance wont hurt ya.

Wont advancing my timing strip out my spark plugs faster and more offten?

Yeah, the 20v is a fun 1.6L engine. It may not be as powerful as a 3sgte, but it's a good improvement over the 7afe IMO. Also, 2.5k (not including the engine) is suggested to be put on the side. This will go to such expenses as buying needed parts that you may need to make the swap a success ie: paseo t. cable, new hoses, etc. Also keep in mind that if you want to keep your a/c and power steering, you will need to have a shop fabricate new lines using the existing hoses and fittings coming off of the new engine. Like everyone else have mentioned, the wiring harness will need to made into a conversion, and the man to do it is Dr. Tweak. He did my harness and it's worth it The exhaust will also need to be welded and mated up to the existing setup or redone from the engine to the rear, whichever you prefer.
