1976 TA23. 2t conversion to Sr20

**Roachy93** · 21-03-2011, 01:27 PM

Hey guys i was wondering what I needed to do to convert my engine to an Sr20, my current engine is a 2t with twin mikuni solex carbies. I have kept everything stock but i want to give the car a bit more of a grunt, im going to keep the origonal engine and parts so i am able to convert it back to stock, but for the time being i want to be able to beat a ford van :L

Um, full engine, ecu, gbox, tailshaft cut and shut, engine mounts, cooling and fuel systems

You'll have to do a bit of fabrication work yourself. A quick list being:

- Custom engine mounts on standard crossmember
- Mod / new gearbox crossmember
- Tailshaft will need to be modified
- Liftpump / surgetank / fuel pump in the boot or under the car
- New exhaust to suit
- Bunch of wiring / plumbing etc
- Might need a larger radiator, some new thermo fans at least.

Other things you might consider is replacing all the steering bushes, upgrading the front brakes. I'm assuming your just puting in an SR20DE, and not the turbo version. Otherwise you may need to beef up the diff, and you'll need a bigger radiator, and run piping for the intercooler. If you want to keep it all legal, you'll need to get the car engineered as well.

No engine conversion is ever simple, or cheap. Be prepared to double your expected costs.

Otherwise, if you want something bolt in, I've got a 3TGTE complete engine package that's currently in a TA22.

Yes im just installing an Sr20DE, i have a mate selling one totally rebuilt one for $250, I have not yet brought it, How much would you like for the 3TGTE? As I would like to keep the engine toyota, but I just want more power then the little 2t i have at the moment.

As Frosty mentioned, it's still a 4 cylinder, but a factory turbo item. For sale thread is here: http://www.toymods.org.au/forums/sho...lf-Intercooler...
$2,000 shipped to a depo near you. A little more costly than the SR20DE, but much easier to install, and it is a bolt in upgrade. Comes with everything you'll need to install. This one was even registered in the TA22 with no engineering or brake upgrades needed.

The Sr20 engine im getting is rear wheel drive.

If your going to bother spending that much money on doing an engine conversion, you may as well go turbo.
The SR20DE will be a nice power upgrade, but for the money it's probably not worth it.
