After seeing DRT's civic i'm quite interesting on how they got that working, ... moreso how they would control the boost, and what turbos would be sufficient enough...

Could two TD04H mistubishi turbos do the job to power a h22a ?

i'm curious on how you would configure the exaust banks to power each turbo, both pistons on the same stroke or on oposites.. to keep the turbines spoolin ?

also this should reduce lag to nil ?

very curious indead..

don't laugh at the topic, if they have one guy doing it, and making low 10 second passes god knows how soon they have that tuned and doing 9 possibly 8 seconds...

pictures or hyperlinks are also welcomed.

 

i've thought about it, i believe it could be done, but with LOTS of fabrication, and even more tuning

 

Why would you want this? The trq from an H22 already makes it a PITA to get off the line. Lag will let you have a resemblence of traciton in first gear.

 

curious... and i have the facilities to do it not to mention i have the time....

I have stainless mandrel tubing, a stainless tig welder, turbos, and a spare motor to start test fitting, i'd be missing the info how to calculate which exaust turbine wheel and what turbos would be best .....

keep in mind i'd like to aquire off the shelf turbos from a manufactured car *easier to source* if one smokes...

I have some Twin turbo Supra turbos' but that would be too much...

also i'm debating how i'd run the wastegate.. i may have to run two independant dial's 35's or 40's ....

doing research first...

block and head fully done allready.

portflow, ferrea's valves, crower pro valve train, crower pro rods, prodrive gears, oil, fully balanced, bla bla bnla bla bloa....

would be different nevertheless... oh and my car is a EK...

 

Well that's of good of a reason as any I've heard. Good luck.

 

that right there shows me you aren't serious.

You're attempting the impossible as it is... so there already is no such thing as "too much."

Room is going to be your biggest and worst enemy. One turbo in an ek is hard enough. Making the piping for two, and then actually shoving two in there is going to be worse. My first advice sinceyou have the bender and the welder is make that front peice a tube chassis and extend the front about 6" so you have space to play with. If you have all these toys, surely you have a friend who could take a one piece fiberglass front end and hack it out, then extend the nose 6"s to fit too.

Maybe with the turbo's offset at a 35 or 45 degree angle from eachother in front of the block. Possibley tring to make a plate and tube setup where they share a wastegate instead of tuning two individual ones.

This is a bad place to ask for insane things like that. We can come up with ideas, we just really wouldn't be able to tell you if it will work. Your best guess is the FI forum.

Just don't tell them I sent you... they all seem to share a common hatred of me down there.

 

i'd rather do testing with two smaller turbo's.. and monitor, the effects... also tune via EGT's and such so i can control it easily... piping does cost much and neither does time.. but blowing a built block does.... i've also got a portable gas analyser so ecu tuning won't be hard at all....

i'd rather start with two smaller turbos so i can monitor and test... buy bigger ones as i monitor the difference and learn from it... i could easily buy some T66's two of them, spend a couple weeks and get the thing start and nail it but i'm certain it wouldn't make the first 10 feet....

so.. looking at the turbo's i'm not worried for positioning that much, i do have alot of space, i'm not going to be running AIR-Air also.. was thinking of a super large PWR water-air.. maybe even two of them one exiting the turbo, then the first bend, and another afterwards before the last bend going into the tb... I don't think the pressure loss is that bad compard to an AIR to AIR also i won't have as much lag since i don't have to build pressure in a bit AIR to AIR unit...

i'm always doubting because i dont' wanna ruin my block....

I'm just wondering why nobody tried it yet except DRT ? funding ?

 

most reasons for twin turbos are because they're on V series motors.

V6, V8, V10, V12 etc. You have twin exhaust manifolds, so a turbo on each one just makes more sense.

That's just my $.02.

Most people don't run twin turbo's on a 4 banger cause you don't need to. A T04 will give you 500-600 whp, and that's about as much as you're going to hold on that thing reliably anyway. Why waste time with more turbo's, that won't give you any more power really.
