2zz swap

Anonymous · March 29, 2005, 00:33

I see GT300 has performed a 2zz swap.. Could you please tell me the final cost ??

Does anyone know a company who would perform a swap for me? As I have neither the facilities or expertise to undertake it myself !

make sure you can insure it first. It's not so easy.

I'm the only known person to have done the swap in the UK. Because of the adjustments and custom fabrication I doubt you will find anyone to do the work. If someone did agree, it would be big £££ because of the labour charge.

£1200 Cost of the engine
£600 Gearbox and ECU
£80 Little Rocket - Shifter Shaft Conversion
£144 Custom vaned intake
£272 Little Rocket Header
£200 Manual Conversion parts
£120 Manual wiring Loom
£250 Dastek Unichip
£150 Unichip harness

£3016 Total

All of these prices will be variable as you can use different parts ie. Apexi PFC instead of a Unichip or OE air filter instead of an intake.

My conversion cost more as the car was an SMT and had to be converted to a manual using the 2ZZ 6 speed gearbox.

The labour to fit this into a manual car shoud only take a weekend between two people (its been done in a day in the US) if you have all the parts available.

Some custom work still needs to be carried out like modifying an engine mount, wiring some of the engine loom, re-routing the dipstick and finding an accessory belt that fits.

Monkey Wrench Racing does this in the U.S. You might drop them a line to see if they can point you in the right direction. But, you might want to ask the question of those that have made the swap if they're happy, now that it's done. The 2ZZ has plenty (of power) on top, but little at low revs or in the middle, where most of us drive. If you're headed for the track, the 2ZZ is probably the way to go, but otherwise....... go with a CAI and an exhaust of some sort. You might be happier in the long run.

another option is speak to Trial about there 3zz option if you're considering the full engine swap but want a faster responding engine

the 2zz is no worse done low than teh 1zz it just has more power up top.

I would actually say it is still quicker below 6000 rpm than a 1ZZ. I know I'm always ahead of Kerrie when staying out of lift (women drivers s:wink: :wink: s:wink: )

I think people perceive the 2ZZ to be slower because it releases so much more from 6000 - 8500 rpm

I did this a while ago, when this subject came up in SC.
(both a whp dynos from Celica, so should be comparable against each other)

Interesting chart. It really shows how the 2ZZ power hits. Thanks for the info.

Jap GT300 · April 4, 2005, 09:46

The chart shows a 2ZZ Celica against a 1ZZ MR2 with pretty close readings and on average the 2ZZ is probably 1-2 whp behind until lift.

I would have thought the scenario would be different in a 2ZZ MR2 though. The car has less weight overall so the hp would be released quicker from the flywheel through the drive train and out of the back wheels.

I would expect a 2ZZ would be averaging 1-2 whp over the 1ZZ graph before lift, if not more.

I think Chris on SC has a dyno so we should be able to plot it up.

Actually it's Celica GT (1ZZ) vs. Celica GT-S (2ZZ), both US models and stock from Newcelica Dyno archives.

Actually the reason why a stock 2ZZ is faster than a stock 1ZZ even below 6krpm is the 6speed gearbox. s:wink: :wink: s:wink:

What about the facelift 2 with the 1ZZ and 6 speed box then s:?: :?: s:?:

AFAIK the 6 speed celica box has lower ratios. The '2s 5sp and 6sp box ratios are identical (1st to 5th of course!)

I didn't realise that the Celica box had different ratios; assummed they would keep them the same for manufacturing and spares reasons.

It's probably just the final drive, but I remember when LittleRocket (at spyderchat) did the 6sp celica box swap into his '2 he ended up with 20% better acceleration from the shorter ratios.

The 2ZZ 6speed has closer ratios and a more agressive final drive.
As mentioned above the 1ZZ 5 and6 have the same 1-5 ratios.
