C25A1 in a 3 gee?

[ICEMAN707]

I have these almost finished pictures that's all. It's one of my buddies buddy, so I dont actually know the guy myself.




I believe the plan is to twin turbo it, and currently the car should be in running condition but with stock engine.

that looks alot like your car in your signature. are you hiding something from us? lol anyways, got any finished pics of that car? i'm curious to see it all done and running. although an h22 would be worth the headache if you are gonna attempt that engine swap instead since the h22 makes almost 200hp.

Nah it's not mine. But they do look like eachother. I havent got any finished pictures but might get it in a couple of weeks.

[ICEMAN707]

is that a factory color for euro accords? nice color.

the first year c25 and the second c27 are not really great motors. But you are better off talking to guys over at acura-legend.com to figure out how to get rid of the vauum lines and get a different intake manifold. Its a very very very tight fit and also need to make an extra mount on the pass side to hold up the motor. Believe it or not, the 3g engine bay from side to side is longer than the legend and the front to back is smaller than the legend. So the radiator and fans need some thinking (atleast the fans). The car will be extremely nose heavy and u need to get the car weighed and run proper spring rate in the front to help the car not dip and bottom out in deceleration and braking and accompanied by the right struts.

No it's pure coincidence really.

just thought you guys would want to see this C series engine while we're on the subject. I don't know how much you guys know about honda's history, but this is a little gold nugget of honda!



C20A. 160HP @ 6 psi FACTORY

[carotman]

That C20A is nice. There was one in the "showroom" of a local engine importer. It's quite big for a 2L engine tough

[HondaBoy]

would this be the legend the C20 turbo came in? seems like it would be. i think so because you see below V6 at the top it says 2000, so 2000cc.


also thought this was cool. a really early nav system. its out of a 2nd gen body legend.

actually that motor is a G20t and they are not very good motors (destroked c25a turbo that produced 180HP/179TQ), you can only get them in an auto and the best part about them is that they have a winged turbo so there is no turbo lag. The whole premise behind the 2L turbo v6 was that they needed a turbo v6, but anything above a 2.0L exceeded the HP/Tq restriction on the car for the times. As for the C25A, alot of the parts are compatible with the 91 NSX motor. I know the pistons will fit and a couple other parts to. You should try and get the c27A internals and stroke it up to a 2.7L then you will have 176HP/176TQ and that little car would be a rocket. As for getting rid of the vacume hoses you would need to get some parts off the 94-97 accord v6, because it uses the exact same motor, just a little more modern.

On a side note I have seen a c27a stuffed into an 89 civic hatch and the only problem he had was radiator not fitting, so he stuck it on outside of the bumper . That car was so fast and was a perfect sleeper.

One more piece of food for thought.

Its an '84 Civic powered by an C25A Acura Legend 2.5L V-6. The bodywork (front and rear bumpers, quater panel flares, fender flares, and rocker extensions) was hand built. A very interesting mix of parts were used during construction. '87 Corvette brakes all around, a Porsche 944 airbox, and 240Z rear suspension bits are some of the highlights, along with many more custom fabricated parts like lower rear control arms.

The car was constructed in the early 90s. It was featured in Sport Compact Car back in February of '94, and again in Turbo and Hi-Tech Performance in February of '97. Full documentation of the build comes with the car. Judging by some of the articles that were in the documentation, the builder toyed with the idea of a Whipplecharger at one point. Also in the binder were articles pertaining to the Ford Festiva/SHOgun, the Renault R-5 Turbo, and the Puegot 205 Turbo 16. All of which share the design of a pint sized hatchback with a big/powerful motor in the back.

There is a ton more to learn. In the next few days/weeks as I work my way through the paperwork I will post any other interesting and pertinent info. Also, I will see about scanning some of the dozens of pictures that document the build.

I would like to see more pics of that C20A-T motor.

actually that motor is a G20t and they are not very good motors (destroked c25a turbo that produced 180HP/179TQ),

I guess you meant to say C20A-T. Cause the G20 was an Inline 5 cylinder motor that never came in turbo.

The C20 was NOT a destroked C25 motor. The C25 was actually a bored out and stroked out C20.

thats right, the G20 and G25 series were 5 cylinder engines. the G20 and G25 i know came in the ascot.

No I ment to say G20t, The turbo legend only came in the 88 and the first c25a was released in 1986 with the original legend and then upgraded to c27a at the end of 1988, so that means that it would be a destroked c25a or c27a. Here is a little more info on the turbo Winged turbo

When I looked into purchasing one of these motors for my legend all the importers I talked to called it a G20T and they are very rare. I did find a couple, but they dident have ECU's with them so declined to buy one. I can't prove that it is the right engine code, but I can't find anything to prove the engine code at all.

Here are some better pictures

That's gotta be the most badass Civic project I've ever seen...but then again I'm a huge fan of the Renault 5 and Clio look...mmmm midengine sexiness. I wish I had the time and money to work my 84' Accord into that!

I about shit my pants as soon as I saw that guys car. He was telling me about before he had pictures and I dident believe him then he showed us those pics and I was like .

Turbo Legend Motor

Holy Shitassmittens that is one beefy lookin' JDM motor. Its funny the only thing that is even similar to the A20s is the alternator.

[accordlxi2.0]

damn!!
a couple of cars i raced asked me what i have...i tell em' stock.

they can't belive that a rusted honda/acura out did there 99' and ^ car.
i did'nt think these engines whould have this much potential....one being i did'nt know that honda made a v6 back in 86'.

i wanna put a turbo in my c27 now.......

[Legend_master]

If it was possible to stick that turbo on a c27a it would scream. It woudl have well over 200+ HP and TQ. I wish I had the money to try that when I still had my legend, but those motors are worthless without the ECU because the winged turbo.

[accordlxi2.0]

(sadly)...ohh.

damn! japan and australia gets better engine than us.....
as for my car...i'm surprised with her performance (even though she needs cap/rotor and o2 sensors)

hey legend master what happen to your legend??

But $700 is a good price even without the ECU...but I'm not sure what the mileage is on that. The shipping on that probably sucks too. Good luck finding an ECU...and what a bitch that would be to swap into anything other than a Legend. Hmmm I'm gonna go see if that Sterling is sitting around the junkyard today.

[accordlxi2.0]

a while back on here a guy in the us found a sterling....but he bought the steering wheel.....
so you'll probably get lucky

[Legend_master]

hey legend master what happen to your legend??

I had to sell it after owning it for 6 years it was my first car, but I will be moving on to bigger and better things once I finish the swap in my hatch. As for the price of the turbo motor it really is not that bad, but you are right it would be really hard to find an ECU or Wire harness for that car.

[phrenology]

I saw the Sterling at the Junkyard again today. It must be the same one I saw months ago, because the hood was jammed like last time. It had some stupid chrome 15's on it that I was gonna salvage, polish and then sell off but the 4th wheel was missing.

I was gonna swipe the steering wheel but it was leather and all chewed up. The interior was dark tan and all beat to shit. It sounds lame but I couldn't find the hood release under the dash. If anyone knows, tell me so I can snap a shot of the engine.

Today I saw about a million A20 Accords, no rare birds though only LX, LXi, DX USDM (I saw an elusive Exi-Si a few years back before I knew much about rare Accords!), couple of 90-91 Accords and Legends, two 2 Gees no hatches damn it (they're becoming a rare find and I need a hatch lid!!!) couple dozen Civics 81-95, two or three Gen 1and 2 Tegs, a Del Sol, no old CRXs! and about a dozen Ludes 86-90.

I was thinking of you guys though, I tried an experiment with some Sterling parts. Unfortunately nothing really worked. I pulled the tails out and tried to fit them onto a 3 Gee but they are a different shape, they might fit a Legend. The front suspension parts are very similar to 3 Geez and contemporary Legends too.

If anyone wants something specific from this Sterling let me know and I can try to pull it for you if it isn't huge. I think the Sterling was an 835 or something, I don't know my Sterling model codes. It was an auto with brown interior. Tell me and I'll go back next week if I can (no promises) I'll charge lot price plus a small pulling fee if its not a pain-in-the-ass piece. Ask me first cause I took a long hard look at it before I left, but keep in mind the engine bay was inaccessible, and the interior is pretty shot.
