C20AT Turbo on C27A???

[CB7Man]

This is an amazingly rare part!
OEM Turbocharger for the C series
And aparently it had some sort of Variable Turbine Geometry that was like an i-VTEC for the turbine...constantly variable.

This turbo made a little ass 2.0 V6 make 190hp!!!!!
The USDM 2.7 makes...what? 170!?

It one of 3 engines honda has ever offered turbo in a production car.
Its beautiful. Its on EBAY right now, the engine doesnt come with an ECU....that was the critical part! The ECU controlled the turbo and everything....

The engine seems to have similar dimensions of the USDM C27

Cool?

VERY COOL

i was researching these things lately ha.

BUT i highly doubt a turbo meant for a 2.0 L isnt going to work well with a 2.7 if thats what your asking

But none the less great find!

[gloryaccordy]

You get all the weight plus some of the 2.7L, w/worse throttle response and 20 more HP. Plus u might have to get the ECU + harness, and of course the harness is made for RHD cars....

I like the idea of the motor and wish Honda had gone more into turbocharging.... but between the complexity of actually swapping and the mediocre chassis available that this would mate to, I would have to pass...

If the ECU controls the turbo then how would you swap the turbo? You either A wouldnt have the turbo working right or B wouldnt have the engine working right. Other then the cool factor of having a OEM honda turbo the engine is kind of weak if you ask me. Its turbo'd but only makes 190hp when an h22 makes 200 n/a

[CB7Man]

Well if somehow this turbo went on the C27, you would have quite a bit more power than an H22, as well as more torque
Im sure some sort of programming could be done to the ECU, or perhaps a piggyback.
You could disable the variable function of the turbo, make it open all the time just like a regular.

But to me a 2.0 V6 is cool as hell, most 4 bangers are 2.0 lol
What would win a N/A 2.0 v6 or N/A 2.0 4-cyl? In the same car ofcourse.

But $1400 for an engine isnt something I would do lol

C20 - Turbo

The C20 was a destroked C25 used to fit in Japan's 2 liter tax bracket. The 190hp was not so much for sport as it was to haul the heavy Legend chassis. I am not going to digress into a lengthy explaination as to what level of technological innovation Honda had achieved by the time this motor went to production, but suffice it to say, the turbo was NOT controlled by the ECU. Yes, you can swap the turbo, the only down side is there is not much you can use off the C20. You would do better to use the C20's design, and not its parts.

First, perform a manual swap from a 5-spd Legend. Then fabricate exhaust manifolds to route exhaust gases to the same spot you see on the C20. Then fabricate an intake manifold to reverse the intake stream (note the C20 intake is facing the opposite direction compared to the C27). Now you can work with something tried and true such as a T3/T4 and even add a top mounted intercooler (such as that found on Subarus). After upgrading the fuel system, and a tune, you should be ready to blow your motor.

Why do I say blow it? 'Cause unless you have money to pay someone to forge and cast custom low-compression pistons and connecting rods, you are going to have to settle for stock internals. You cannot breeze into your online retailer and order low-compression pistons for the C27. Having internals custom fabricated is the least expensive option, others include using modified C32 heads.

If I had the money to fabricate custom internals, I would not limit myself to the C20 design, I would use two T3s and make it twin turbo.
