Twin Turbo might move forward!!!
 

so, i think i finally might be able to move forward with my TT setup. I sourced about 5 IHI RHB5s from various 80's subarus. turns out, given the right wastegate settings the RHB5 can push about 11#. The junk yard wants 55 each, so i can get a couple, clean them up and move forward. That is if the fiance and i can come to an agreement about it. These turbos are tiny so they can easly fit where i want to put them. If i can get the turbos, it shouldnt be long before i have a TwinTurbo running. :D :D :D

Go get them DRAGON:D :D :D

Tt?
 

Best of luck with the project if you can get it going.

Just on a point relating to available power, I would have to say that using two turbos rather than one is more complication than you need to take on.

You will have to feed exhaust gas to each turbo, requiring fabrication on each side.

My brother has a 4cyl Forester Turbo from Japan, '97 model. It has only one turbo. It is a relatively big one, a TD04 I think it is, and the car makes about 240 hp.

Now if you run the maths on this, 4 cyls, 2 litres and one turbo producing 240 hp.
So the SVX with six cylinders, more than 50% more capacity, and using the same turbo setup, it has to deliver more than 360 hp. Plenty enough power I would say, for half the complication and the fabrication.

However, if you have your heart set on having a twin turbo SVX, I will look forward to seeing how the progress goes.:)

Keep us posted,

Twin turbos.
 

Twin turbos on a six does fix the interferance problem that is caused in the header pipes joining before the turbo. I reckond that is why most six cylinder engines use them.

Harvey.;)

my thinking exactally. and this will involve less exhaust work. and the turbos i am looking at are small enough, to mount about halfway down. so less exhaust and cold tubing to fab up. Another reason, our headers just beg for a twin setup

Sounds good.

Go for it, as my son would say....

:D

might want to rethink location. Having had plans and SEVERAL parts for my TT setup I found the best location would be to remote mount them in front of the front tires. Get rid of the ABS and relocate the batt to the trunk. It is your best bet my friend

Tom

intersting idea. i might have to consider it. ill have to do some measurements. i think that the turbos i will get, will be small enough, and facing the correct direction to mount where i had planned... now for another issue i havent quite worked out. Will i need to run double MAF?

So is that the round-a-bout figure our cars pops out, turboed, for the people here who are at that level? If so that's awsome. We are talking about straight connection right, running 4-5 psi, no lowering compression, beefing nothing up?

my setup for now will run on stock internals. if all goes well with an engine on stand. i will make it a power monster. whole 9 yards. so this first TT will be kind of a test period.

No you will not need to do that. You can run both intakes out of a single collector. Take a look at how a 300zx tt works and you will understand it better

Tom

cool. that will save me from doing lots of extra electronics work.

yeah, this can be done....

This is what Tom was talking about, re: going with a single MAF
(no A/C:mad: )

(major kudos to PhatSuby!)

Bill, the intakes before the turbo's is where you will need to place the MAF not post intercooler. It is a tricky setup and will require oodles of fab work and a lot of custom piping to be cut and welded

Tom

Tom,
Seems to me I read where there are some folks running their MAFs post intercooler...I'll have to go dig around and see if I can find how they made it work...
