3S-GTE/Turbo MK1 Engine twin charged - Page 3

okay well now im wondering about air to water intercooler be better for an mk1 because not as much air is in that part of the engine bay?

Kevin I scored this for Aus $37 on ebay & $20 gas to pickup ;]

Bench tested it matches an Evo 9. 2½" both sides will outflow a 9.
Cheers !

okay and will it help a mk1 tc set up?

also i made this on paint and these are my 2 ideas.

2 intercoolers

1 intercooler ( all the labels are the same on here )

Any suggestions would be appreciated especially what turbo to use?

My w to a IC is 3" think. I don't know if it will fit without a hood mod.
It has a low resistance back on the pumping source, my turbo.
So the load back on my turbo bearings are low, turbo lives longer.
It's not the coldest IC out there, but quicker responce time for me.
divO is going to use w to a for an all round street car like me.
Bridge 2 of these or smaller with one water supply for twin charging
& plumb it feral4mr2's way to keep it easier for you to build.
Still big $$ unless you can fabricate a lot of the custom work.
Cheers !

I have a twincharger engine in my mr2.
It has the same setup that the golf tsi has.

Homebuild manifold.

I'm quite interested in your setup, Sethro. Can you provide more details on how things are routed and if you are running a supercharger bypass? It is quite difficult following the all the plumbing from your pictures.

I'd be interested in details like
- Detailed specs on your turbo
- Total boost you are running
- Boost threshold RPM
- Full boost RPM
- Any perceived lag

As my project has been progressing, I've been trying to calculate the expected turbo boost threshold for my setup, but I have not found any good references for predicting boost threshold. So any empirical data is appreciated.

I will try to draw a drawing of the setup.

The turbo is a garrett t3 from Fiat croma turbo.
I will runing that turbo to max 1.1-1.2 bar.

The engine is started. I have not try to drive th car whit that
engine yet.

The car is not finished yet..

This is old pictures. This is from i have just the supercharger.
I have used the intercooler from levin 4agze. That i have wraped
is with aluminium. And it used water pump from celica st205.
And the old a/c radiator that was on th car. Who needs a/c ? :-)

Thanks for the details about your build Sethro. I'll be very curious on how it all works out.

I won't be able to use your results to predict boost threshold, since you are going S/C --> Turbo, while I'm going Turbo --> S/C.

Keep us posted on the project.

Feral4MR2. so know when u twin charged your mr2 did u mod the internals or keep them stock? and also so your idea is running the turbo into the sc into the ic to the intake. how does the sc know when it disengaged if their is constant pressure from the turbo in high rpm. and do u know of any cheap turbo exhaust manifolds for the mr2?
