My 1991 Talon TSi Compound Turbo AWD

[pgfpro]

Wheel Tire Update:

Mounted my Rota Grid wheels and QTP Hoosier's tires today.
0 to 60mph in 2.5 seconds or less



These will be my track and sometimes road tires for to and from the track. My goal is to drive to the track, run a 9 second 1/4 mile then drive home.

I'm going to install the coil overs next week and drop the car about 2".

Buggati who?

Thanks guys!!!

This car is going to be whole lot faster then I originally thought, so its time to have my welder friend cage it.

Speaking of my welder friend Eric, hes got the turbo box tacked up.

Update:
Final fit on the turbo box.






Now I will drop it back by the welders tomorrow and have him finish welding it up.

Next I will purchase a CO monitor from Sata #SAT X144 just for extra precautions.

I'm going to order my 3 gallon recycle solvent fuel cell today. This will sit in the passenger side rear trunk area. I'm going to run the solvent line to the low pressure turbo inside the box and do a four coil wrap around the turbo up pipe.

This will be the first stage heating coil for the solvent. Then it will go to the control flow valve, then through the fire wall to the secondary heating source, the heater core inlet hose with a 6 wrap.

What I have found interesting is the recycle solvent needs to be heated to a least a 175*F. It mainly made up of Toluene and heating is a must.

I know this is a ton of extra work but I think it will pay off in the long end.
My best tank so far is 44 mpg at 65 mph running ultra lean burn. Running the recycle solvent I should be able to get around 60MPG, based on the recycle solvent is free. As of today I have ten full 55 gallon drums waiting to be used.

I've been slowly working on life efficiency. I currently own 2 1990 Honda CRX HF's stock with over 200k miles. I'm only getting 41mpg in my DD but I've started working on mods so far including a hot air intake and small grill block but will have full aero mods minus a boat tail or anything that will cause serious rubber necking. I've looked at this thread and even sent it to friends/colleagues. We are interested in starting to do a setup similar in our CRX's however I'm hoping you can guide or offer insight as to exactly what we can do with our engine to kick things off in the direction of better MPG. I think your car is fascinating!

First, Thank You for the kind words!!!

I would be glad to help in anyway I can? I did a few Honda's a few years ago and had some great success with them. Is your CRX EFI?

I'm also thinking about building another Honda VX with a management system and turbo compound system. Of course after I get this one done.lol

And I've researched a bit but don't see anything major you can do to this cars engine . Do you have a suggestion on where to start with this? It don't have lean burn and mostly gets it's efficiency from running at 2k rpms at 70 MPH on the highway and low rpms as I can pull a hill at 1000 rpms in almost any gear. I mean yeah the small intake and 1.5l help but I'd like to get into the 60s without too much coasting if I can? currently only getting 41 and I keep a steady speed and speed up down hills and slow down up hills when possible.

The first thing I would do is get a management system. I love the Neptune RTP.

1988-1991 Civic/CRX Si-HF or swapped cars (can use OBD1 ECU and OBD1 tools with OBD1/OBD2 distributor swap and conversion harness)

Once you have a tunable ECU your gains will be worth it.

Then it gets into how much you want to do as far as the engine build and a single turbo system or a turbo compound system?

My major fuel mileage gains are from lean burn with zero intake pumping
losses. So keep in mind your local state might have some issues with you running lean burn and emissions.

The other thing to keep in mind is when my car goes into lean burn and ultra lean burn it takes some time to get used to the power loss and the throttle. Your first instinct is to let off the gas and and start to pull over thinking the engine is going to stall.lol I recently got the pleasure of driving a VX Civic with lean burn and my car is 10 times more sensitive when it goes into lean burn. The average driver wouldn't even want to drive my car because of this built in hole in the tune.

Anyway I hope that helps.
