yes

 

I'm glad to see that you are taking on this project. It should be a lot of fun watching you do it. I have complete faith in you if you decide to definitely tackle this project. Prove 'em wrong Christian

 

there's a discussion about this already. im moving ithis to the same area. mmkay

 

Youare the absolute sultan Christian :bowdown::bowdown: more power to you and i REALLY hope you get this to work because this will beable to smash just about everything on the road, i have no doubt mid 12s easy for some reason. ANywasy you are and will always be the King of Chances. im glad you are on my team (Legend team):bowdown:.

one question though, i noticed you call the C-series by CA. all literature i have found and the block its self (mine atleast) says C32A. i dont get why you call it the CA32A...please inform me

Thanks, ill be looking forward to creating a real true Hybrid swap. The fun part about all this is i have to change out the block out of nessesity, so why not slap a 3.5 in there if i can.
All my friends are sayin mid 12's too but i cant see the engine handling that kind of power. we'll see what condition the block is in when i pull her out.

CA32A1...it's C32A1....i dont know what your talking about........

~Hybrid

 

excellent Christian!

I really look forward to seeing this finished product.
I do know that the 3.5RL (newer) has a lot of oooomph. In a lighter chassis with mods it should run even nicer.

 

Re: CA32A1 Head Gaskets- CA35A1 perfect match

If anyone can come up with anything else please let me know.

~Hybrid

Shouldn't the longer stroke on the 3.5 require different cam timing? I gather that you plan to use the stock 3.2 heads and cams? Are you concerned about the clearance between pistons and valves?

I think it will be OK, it is not that close of a call between TDC and valve timing that the 3.5 bottom end topped with 3.2 heads will interfere. Your timing would still need to be way off. I think for the initial development of a hybrid 3.5/Type II combo he should be fine running stock valve train and stock injectors. If he is running lean, he can always get slightly larger injectors while leaving the stock ECU alone. I think DV8 already has a bored T/B and P/P heads, so feeding the bigger cylinders should be no prob for this setup.

way to go man, let's put more REAL projects into the Legend community. It makes me so happy to see the progress being made with hybrids and swaps, hopefully the rest of you guys stop whining about gutter guard and 20" wheels and start helping out on the real modification aspects of the Legend!!!

DV8, maybe I will buy a 3.5 motor also, would you be willing to share technical info? I think it would be better if more than one person was attempting this, and you know I ain't afraid of tearing into my car.

 

DV8... all the power to you man!

Are the exhaust ports the same on the RL block as they are on the Type II? I hope this won't change your "header" project efforts to be focused on developing them for the RL block instead of the Legend... but if they're the same.. then cool! :2cool:

Hey, don't get me wrong. I'm not trying to rain on DV8's parade. Rather, I think its a cool idea, and I'm tyring to help.

The Legend has a 84mm stroke. The RL has a 91mm stroke. So, if the two engines used the same pistons and con rods, then at TDC the RL pistons would be about 2.5mm higher than the Legend. That wouldn't work -- so Honda must have changed the piston and con rod geometry in the RL. And my point is this: if the pistons are different, then the shape of their dome might be enough different to interfere with the Legend heads. The fact that the head gaskets match is not sufficient evidence to deduce that the Legend heads will work without interference. Suggestion: put a wad of clay on a piston, bolt up the Legend heads, and then rotate the engine through 2 crank revolutions by hand. Unbolt the heads, and look for impressions in the clay. That will tell you about clearances. Try same trick on the 3.2 block and compare results.

OK, next point: cam timing. A longer stroke leads to higher piston velocity at given RPM. That higher velocity affects gas flow rates in and out of the combustion chamber. So, the timing of the exhaust and intake valves should be somewhat different to achieve the optimum result. Suggestion: perhaps one of those adjustable cam sprockets is available for the Legend, or maybe something for the NSX can be adapted. Assuming the hybrid engine runs, then some careful experimentation with cam timing my result in significant changes in performance. But, be careful about piston/valve clearances!

Good luck,

to an amateur like myself, a lot of this is over my head. Nonetheless, this is a very exciting movement in the Legend community. I can't wait to see how everything works out. Good luck Dv8!!

Now that is using your head! Prob with adj cam sprockets is that we are SOHC, cam sprockets are basically "bling" on a SOHC. Well, this project needs to be jumped into by somebody. You are bringing up very educated points, but I think it is best we just wait and see what happens. I had to ignore alot of educated "your gonna have problems" or "it is not gonna work because....." when I did my trans swap. You just need to get in there and do it! If there is problems, then ya make it work. If he has problem with cam timing (which is a valid point) he could always research the Honda swapping communities and find excellent info on basically the same issues from the 4 banger guys. No worries........

Where was my mind!?! LOL. That's right! My careless mistake! DUH! <smackin myself over my head on this one>

Cap its easy to get cought up in technical stuff and rest assured i will check it all out once i get the engine here, i got hooked up with block and heads from a RL so ill be able to compare with the 3.2.

My genral rule of thumb of all this is the B series engines b16's b18's and b20. Take for example the b20, you take a b16 head(head of choice by most) and it fits and works with no problems and thats stroke twice over than the legend vs RL. Obiously i dont have more technical assurance, but if there wasnet risk involved everybody would alreay be doing it.

Ill bet you anything the pistons are exactly the same and their TDC is as well. They share virtually the same compresion ratio and besides why would HONDA make up a whole new set of pistons when the legends would work fine. think like a business man when it comes to engine building and youll see that crossing many of the same parts saves money. thats exactly what Honda does. Especially nissan with that 3.5 v6 its in everything.

When it comes down to it, ill find out when its already to late.

way to go dv8

a lil off subj but could i do the same with c30 heads on my c27 they are the same idea in reverse right???

 

Cap you are thinking too hard. not tryin to "cold bust you out" i hope i dont come off like that. but with what you said theres a major draw back, the pistons, if located in the same spot, will be in the same area though traveling faster. the crank travles twice as fast as the cams so in 1 revolution 3 pistons will have fired, whether the stroke is longer or shorter the engine will fire 3 times per rev. the rod angle and piston speed will increase but with the increase in speed it is matching the spots where the shorter stroked C32 is. the cam timing may prove to be a little off for the Displacement but what i am thinking is that with the Legend strong topend it is possible to not worry to much about it. On clearance, Christian is not removing the crank from a C35A and placing it in the C32 block, rather he's using the C35 block so what ever honda did to make sure the block wasn't too short for the added stroke is what will keep the clearance issue to a minimum. no matter how hard you try, a factory engine's pistons will not come past the block surface. the Legends Pistons are of a SLIGHT dish style more of a flat Dish style and have Valve reliefe cuts in them to minimize valve contact, and as such the C35 SHOULD have the same style pistons, having not seen a naked C35A yet im flying blind. Anyways, the breathing (cams and what not) im thinking shouldn't be too much of a problem as he plans on making his C35 a "running shoe" engine rather than a loafer.

 

hey dv8 or nickd i got a fully rebuilt type 1 heads i will donate to this projcet to see it run.. im serious i always wanted a fast legend since im runnig out of stuff to do to it soo lemme know nick d im in the nyc area so lemme know...jon

For a topend to the 3.5 block
Ive got Port and polished-gasket matched TYPE II intake manifold, exhaust manifold, heads, 3 angle valve job, direct port NOS and KMS honed race Throttle body(semi custom). on paper this engine should scream.

On clearance, Christian is not removing the crank from a C35A and placing it in the C32 block, rather he's using the C35 block so ... a factory engine's pistons will not come past the block surface.

I concur. But for that to be true, then the pistons must have a different geometry than the 3.2 pistons. That's all I was saying.

the Legends Pistons are of a SLIGHT dish style more of a flat Dish style and have Valve reliefe cuts in them to minimize valve contact, and as such the C35 SHOULD have the same style pistons,

You say "should." I think we all "hope" that this is true, so that DV8 will have one less problem to overcome, and we can all enjoy his success.

So, you believe that I think too much? I've heard it before,

Hybrid Project

Hows it goin guys, this is a great idea. I defintely think it could be done and I'd like to help out in anyway that I can. I have a 97 RL turbo and I think if this project worked out it would make a great deal of extra power out of my turbo. If I can help in anyway as far as the RL aspect of this project is concerned, please let me know. I have all kinds of wiring diagrams and schematics and manuals for the RL. If you think you could make use of any of these things please let me know. ALSO, in case you happened to have been browsing ebay, there are currently 2 RL engines for sale. The one being sold without fuel rails for $700 which is being claimed to only have 35k on it really has 118k and was nitrous fed for the last 25k of that. I'm not sure how that guy got my engine or why hes selling it, but I knew it was mine because he forgot to take the blue wire covers off and the small yellow rubber hose I had off the breather. Just a heads up, Good luck with the project, I have faith.

Whoa, there.
Im the guy doing all this and Ive seen your mod list up on car domain in the past week while searching for RL material, however, i among others would love to know where and how much for the turbo manifolds.

Now about the swap, dont u already have a 3.5 RL? what do you need to benefit from? The Legends topend? I dont understand.

"I have a 97 RL turbo and I think if this project worked out it would make a great deal of extra power out of my turbo."

we are talking about taking a RL block and putting the Legend TYPE II heads on it, then putting it in a lighter Legend.

Anyway i need engine block diagrams, do you have them?

Let me know ASAP.

IF ANYONE FLAMES THIS THREAD FROM THIS POST ON, BECAUSE OF certain DESCRIBED MATERIALS ABOVE, I WILL PERSONALLY BAN YOU FROM THIS SECTION. IF YOU HAVE A PROBLEM WITH THAT pm ME

Do you have some mean turbo lag? Looks like your turbo is after the "Y"
Anyway, I am interested in your fuel management.....I can help you get a 6 speed in that ride if you wanna show me your fuel management
