If the Lotus Elise had no trunk, these engine upgrades just might fit.


Trial Supercharger for 2ZZ-GE

Blitz Supercharger for 2ZZ-GE

Turbo Technics Supercharger

Although the Turbo Technics supercharger is not for the 2ZZ-GE, it is the right size to fit in the Lotus Elise engine compartment. It might work well with some engine modifications from Monkey Wrench Racing.

I have come to the conclusion that while the 2ZZ-GE is an excellent engine, it really lacks good tuning options. A Honda VTEC would have been a much better choice.

The big problem is getting sufficient airflow across that intercooler.

You might also need to upgrade the front radiator and install some electric fans in the boot to pump hot air out of the engine bay.

Heat generation is a *big* problem with FI midengine config.

The Turbo Technics supercharger kit (for the Rover engine) addresses the heat issues with a charge-cooler radiator and oil cooler mounted in the front clamshell.

the problem with mounting the intercooler in the front clamshell is the amount of distance the air will have to travel to reach the engine. This is not a huge deal with a supercharger but if there is a turbo in the mix this could be a deal breaker. I will increase lag by a good bit making the turbo potentally suck.

how much is the Mr. Gasket "the beast?"

damn 1.8L 270 hp NA. sign me up. It will be heavier than the 2zz, but you'll be getting 30-40 more HP than if you were to FI the toyota engine.

Damn, 270....i didn't see the inclusion of a transmission?

No transmission, intake, or exhaust are included with the GX20 engine. Plus, you would need a Honda conversion kit.

you'll end up over 25k easily. Forget it...even though the Elise will kick total ass and be hella unique. power to weight ratio of a Z06.

No, this is not an air-air intercooler, but an air-water-air chargecooler, so the air does not travel all the way to the front...

On the engine side there's a heat exchanger, then a water circuit (separate from the cooling system) to transport the heat to the front and a radiator/heat exchanger under the normal radiator.

Look at the Lotus Esprit turbo's. They always used this solution and it is basically the *only* real solution to cooling compressed intake air on a mid-engined car.

Regular air-air intercoolers mounted in/around the engine bay in a mid-engined car will always be severely compromised in their effectiveness as they are not in enough airflow.

Bye, Arno.

If you are set on an engine swap and would like to save a little money, you would be better off buying a "complete" Honda K20A and having it performance tuned. There are many tuning options for the K20A that could bring NA horsepower up to 270 HP.

The 2ZZ-GE can take a little boost as long as you use the right spark plugs and 91 octane fuel (or higher). Based on all I have read, the best you are going to safely get from the 2ZZ-GE with FI and no internal engine modifications is 260 HP. Although, higher boost can be achived if you harden the engine internals and lower the compression.

There are many tuning options for the K20A that could bring NA horsepower up to 230 to 270 HP. A couple tuning options can be found at the TODA Racing and Hondata websites.

On the other hand, you could explore your options with the 2ZZ-GE by taking it to a tuner like Advanced Engine Breathing Systems (AEBS).

The 2ZZ-GE can take a little boost as long as you use the right spark plugs and 91 octane fuel (or higher). Based on all I have read, the best you are going to safely get from the 2ZZ-GE with FI and no internal engine modifications is 240 HP. Although, higher boost can be achived if you harden the engine internals and lower the compression.

At this point, I think the only viable FI option for the Lotus Elise is the Turbo Technics supercharger package.
Or you can get a TRD crate engine for $8500, 230hp
Trial USA stroked 3zz crate engine for $5500, 220hp

+ PowerFC tuned 10hp.

Here is some info on Nitrous for those interested ...

Zex Wet Nitrous Kit



According to many Toyota 2ZZ owners out there, no more than 55HP boost should be used with stock internals and tuning.

You're forgeting one thing the intake of the Toyota faces the firewall not the boot. The K20A can take a supercharger (in the S1 at least) - so maybe it will fit on the Toyota (no doubt someone will try). As an owner of a Honda powered Elise provided by Prototype I would be wary of parting with any cash. There are issues with the kit and with the power claims. But the engine itself is a real gem and will gobble up Toyota powered Elises all day long :p

Centrifugal blowers are only going to make reasonable power from 4,000 on, and good power from 6,000 on. Your low end tq will see little to no benefit. Given the compression ratio of the motor, you'll be looking at a 6psi kit, which is good for a whopping 2psi at 4,000 rpm.

You'll add lots of heat to the motor, will likely need extra cooling capacity in form of a better radiator and a second oil cooler for long term reliability, all while deviating from the subtle throttle response that Lotus designed into the car, which plays a role in handling at the limit.

Nitrous properly managed would be fine, but unusable where the Elise is in its element, backcountry roads and the track.

Just my opinion of course. I'd be more interested in a crate motor.

I always thought the 2ZZ was a great engine to build up N/A. Others have said the head on the engine seems to flow so well that it's just asking for boost. Cams, standalone ECU, port/polish, higher C/R, ITB's, stoker-kit. all this should work fine with the lotus, maybe w/ the exception of the ITB's.. would have to see how they fit in there.

Does anyone on this forum own the 2zz-ge Trial Headers for the Lotus ??? :confused:

If so, have you experienced any performance gain with it? I am wondering if it would beneficial to have it on a supercharged Exige? Its necessary for any supercharged Lotus to have bigger piping on the headers than a NA Lotus, correct?

sorry for not having an answer to your question, I just had to comment that this is likely the deadest thread ever resurrected! One page, and last post was july 2004!
:eek: +1 If not the deadest, it's definitely in the running.

With respect to the header, I would think that if it were readily available or offered appreciable gains there would be a number of threads on it, considering that there is quite a number of pioneers on this forum. As there are very few, I'd think I'd look for other options. But, then again, I could be wrong.

rotfl Yes, I know its an old thread. So I've decided to start a separate thread about this under the "Drivetrain" section (forced induction).

I am curious whether there has been an improvement on the OEM header that comes in the forced induction Lotus like my Exige S. I wanted to know what the diameter of the piping is and if it has been increased on FI cars. If so, it might be pointless to go with an aftermarket header since most of the aftermarket header were designed for naturally aspirated Lotus and perhaps the Lotus Exige S may have have bigger pipings on the header. :shrug:

Search (on the lowly newcelica.org econobox forum) and ye shall find...

Before and after the installation and tuning of the Trial header on a Greddy Supercharged GTS (same shorty header):

http://www.newcelica.org/forums/showthread.php?t=227690

Before:


After:


But for the price on sites like kinwaymotorsports.com or japanparts.com...the larger primaries more suited for supercharging doesn't make the price worth it when you're right under the price of the PPE race header Dave used to hit 248 whp with only a 3.2" pulley and standalone ECU tuning. Plus without a custom tune, you can't make most of the header, and even Boosted2.0's $155 stock ported header service has been known to provide better all around and more consistant gains for an unbeatable price.
