That's actually my project.
Whipple Twinscrew with quad-core Laminova ATW IC.

I have a spare engine on its way, and have also contacted 6 different suppliers for wiring terminals to be able to do harnesses. I have A LOT going on all at once at the moment. But I taught myself CAD to be able to design my intake manifold. Now I have the issue of having to teach myself how to get my 3D design into 2D for .DXF export in Fusion 360.
Then I have a Waterjetter lined up for that.

Then I have to design my belt pulley system.

If you can make a kit to fit a whipple 3.3L onto the 2gr, I will the first person to buy it :)

Honestly, about 6 months ago the 2GR swaps all but completely died out. Most of this seems to be related to the Brexit instability because most of my market was overseas so I'm in a bit of a holding pattern to see what comes of it.

I'll still sell the existing parts for as long as it makes sense but the switch from about 12-15 kits per year to about 4 kits per year makes it not make sense to support this platform. I think i waited too long to finally get this supercharger stuff out there.

I still have two of the routing kits available out of the nine initially produced and people can buy those to go with the lotus charger but i don't think i will even bother putting these on the web-site for sale.

That said, I'm developing new stuff, trying to pick up the MKIII market and I'm trying to hit a completely different price point with that stuff to make the swap more appealing.

Something like these
and
? I am not very familiar with these style of intercooling. Is it more efficient or at least as efficient as "external" intercooling ?

Laminova cores are pretty fantastic for intercooling. they tend to be very compact and offer good heat transfer characteristics without needing to be custom sized for the application. the flip side is they are a bit spendy.
 
#145 ·
They can be speedy yes, but there is so much surface area per core with VERY minimal pressure drop.

There are a few OEM's out there that have used them too. GM has used the Laminova cores in the Cobalt SS and some of the Cadillac S/c vehicles. Although they are non-standard core lengths.

The advantage to these things is their compact size, laminar flow with little pressure drop and incredible surface area.

They also make cores for fluid heat exchange. Oil coolers ect.

Damn so supercharger quest has ended then Gouky?

Let's keep in mind, i did make a way to get a supercharger on your 2GR. Yes, the parts are rare but there's more than enough superchargers out there to satisfy the people that really want one on their car.

That said, I'm going to put more effort soon towards the ECU. The TRD tune was a bit lackluster and frankly the stock tune feels much better. With the work I'm doing on the MKIII 2AR-FE kit I plan on following that up with a turbo option and that will require me to dig into the ECU and finally find the fuel injector sizing stuff. There's a good chance that the work there will get ported back to the 2GR.

but as for making a bolt-on supercharger for this motor, i just can't make the numbers work out with the demand in the MR2 market and the other markets would require ECUs to be figured out more before they can be supported.

Music to my ears!! (The ECU!)

I heard that ECU Master is going to release a new ECU in 4th quarter of 2017 that has 4 trigger inputs that will be able to support the 2GR. I remembered you mentioning you might do Haltech ECU tune at some point, and this might be another option.

This is still a possibility. send me the info. but likely the effort for that kind of stuff would go towards the 2AR-FE at this point.

It looks like the MS3Pro Ultimate ECU has 4 VR inputs
https://www.ampefi.com/product/ms3pro-ultimate-standalone-ecu-only/

VVT Control (4 channels)
- Open loop VVT control for 2-position camshafts
- Closed loop control for fully variable camshafts
- Controls up to 4 total VVT camshafts

I see that they have just made an adapter harness for the Lotus ECU. This is great if you are coming from a Lotus ECU, which to my understanding is quite different that the Toyota ECU the majority of us are using. The Link Fury does seem like a pretty nice ECU.

MWR sells a Link package as here well, although wire in.

My understanding is that Lotus uses a standard Toyota engine loom (and connector), but they use a proprietary connector for their body side connections to the ECU.
If thats the case, an off the shelf adapter harness for the Link Fury standalone would allow the engine harness to plug right in, but some adaptation would be required on the body side.

To anyone still interested in a TRD/Lotus TVS1320, I do have one currently for sale.

Mainly, it’s posted on the FB Marketplace.
S/C with approx 50 miles, factory S/c lower intake manifold, full set of Toyota Blue 500cc injectors, and Marc’s upper idler pulley assy.
