Supercharged rolla

[tenyearguarantee]

My brother in law in the UK is looking at this. I never knew these existed, looks fun

mmm..  drop into a KE70 nicely..  225bhp if you buy the right motor!

No wonder those Lotus' fly!

I'm tempted to go supercharged on my 2ZZE102 but I need to see how much clearance there is to the radiator (plus I actually have to do the conversion first, baby steps....)

I was just looking under the performance and economy tab on that link 215 BHP. Up to 35 mpg on the open road. What box would u put behind it to jamb into a KE55.

You'd jump the T-series, they're too old & worn out, and go straight to a J160 6-speed.

Then you need an adapter plate to fit it on the motor if at all possible with input shaft dimensions, and the room in the car to fit a rather large gearbox.

We will all come to this problem as our K boxes can't be rebuilt as there are no bearings anymore, T boxes can't be far off the same problem, and there are no small RWD gearboxes in the Toyota range.

Big problem with RWD-converting 2ZZs is that there aren't spots on the block for the engine-mounts, since they were only ever a transverse installation (in the Corolla/Celica/Lotus/MR2 3 of the 4 "engine" mounts actually attach to the gearbox)

 

Assuming that could be sorted, J160 would be a no-brainer.  2ZZs _need_ a 6-speed behind them to keep them on the boil, even with the stock C60/64 gearing they drop out of lift going between 1st and 2nd unless you slam the change and slip the hell out of the clutch, which is why most people fit aftermarket ECUs/piggybacks to lower the lift engagement point (that, and Toyota deliberately programmed it higher so that the kick was more pronounced, not faster)

The Locost guys have been onto it for years it seems-

The lack of block attachments for engine mounts is something I'd never thought of. His solution is not ideal, but I can't see any other way.

Comments from a guy who owned one of those Rollas was that it was uninspiring but adequate in traffic going to work..  and an animal over 6000rpm when the dual valve lift/timing hit!  So you wanted to drive it over 6000rpm all day.  Someone else said there were chips to lower the cut-in revs. Old motors now, for blocks that can't be re-bored.

You can over-bore and then sleeve them, Bill/Xoom did this in his turbo ZZE123 Sportivo.

 

I lucked out and got an engine with only 127,000k on it, should still be factory-fresh.
