Os Giken TG24-B1 heads

[badintentionz]

Thanks for your replys. Well now I know it's suppose to be TC not TG, thanks. I see all of your points but it would still be nice to have them around again. If you still want to try to support me on this, that would be cool. If not, it's all good, I can't make you do what you don't want to do. Anyways, thanks for the info and wish me luck.

I remember reading in another thread that only something like 11 of the LY motors were ever produced, someone please correct me if i'm remembering wrong.

It was a low number of LY's for sure. v12horse (Ben) got to ride in a RHD with a 2.9 liter LY. The owner of the car said he paid $60,000 for it 30 years ago. Yes, $60,000.

Hey Victor, how about a loan?

I think you'll find that we all support in in your endeavours to have this engine, however the majority of us do not have spare cash like this to assist you in underrighting a major project like this.

I'm sure all that have replied, indicating to you why it's no longer manufactured wish you every success and I'm sure we all would like to see a 240 powered by of these rarities.

Please keep us all informed of your progress on the project and good luck...

Eric, it would be great to have one of these TC24 heads indeed, but besides being very expensive, they are extremely hard to come by from what I have heard. If it were to cost 20K to get this setup, I would some day love to have one. I have a lot more to learn first as well as a lot of money. errr. However, I have a feeling that 20K would be too little for one of these heads and engine sets. From what I read, everything is changed- the head (duh), the pistons, crankshaft. etc. Correct me if I am wrong. In a different thread about these engines I believe Alan says that the people that do have these are not going to give them up. Why should they? The TC24 is a beautiful machine and it is a museum peice indeed. By the way Eric, if you are able to contact OS-Giken on this matter, I am sure that we would all be interested to hear what they have to say, even if they crush our hopes and dreams of one day owning a DOHC L-series powered Zed.

As far as the LY goes, there is no such thing as bang for your buck. It will be crazy expensive, but well worth it in my opinion if one has the cash. Mr. Akamatsu told me that he payed 60K in USD in 1979 for 2 LY engines. I have heard that there was an LY on Yahoo Japan auctions that was being bid on for 60K USD, but I am not sure when this was. One of my friends that is not a member told me this. Gav, I would take a LY over a P90 any day. I am sure you would too. hehehe. I am not sure on bhp on these heads, but the engine that was in Mr. Akamatsu's car had a grip load of power. It was no 5hp increase. I do not want to make guesses about its power, but let me tell you- if felt faster than being in my friends Corvette (C5), and he was flooring it. Mr. Akamatsu was not stepping on the gas.

Ben,

Since you didn't want to make guesses, Here is a page dedicated to Akamatsu's LY-powered 260Z. Power figures: 300HP / 232 lb/ft, 11.7:1 compression.

The results seem to go along with the obvious performance of it chasing down the OS Giken Bluebird.

*edit*

Apparently it is a hand-copied page from SportCompactCar.

Thanks for the link Phill. I don't think that Z that is chasing the TC16 powered Bluebird is Mr. Akamatsu's. If you look carefully you can see that the lights are from an earlier car. I could be wrong. It is great that more people are getting interested in these engines. I have learned more about them since you started the other thread. Thanks for sharing the videos. I really hope I didn't seem like I was demeaning because I was not trying to be. I really don't know much about the subject, and I would like to learn more.

Take care,

Ben

Thanks guys now for the last few days all I can think about is an LY or TCB-24 engine head on my L28 .

What i found interesting is that Yasuhiro Akamatsu's car is only what appears to be an L26 bored out to L28 spec.

Imagine this set up with the 3.1ltr w00t

The imagine what the twin cam 24 valve could do with two turbo chargers ok I am dreaming but Alan T did have a pic of such a set up. One could only dream but then again one should just buy an RB26

I know what you mean Gav. I think my problem is the addiction for Vintage modified... having a timeless engine designed in yesteryear and watching it compete competently against newer motors. Its a hard pill to swallow, knowing you have a better chance of being struck by lightning than to acquire a crossflow Z head.

As an aside, I'd love to see what a naturally aspirated RB26 could do.

[v12horse]

Hi Gav, I don't mean to be picky, but it is "TC-24".

As far as Mr. Akamatsu's Z goes, he told me that it is a 2.9 ltr engine. Once again, I really don't want to be picky.
