Hi
I have some questions on my Prelude engine that I have not been able to get answers to. .
I have had my UK Prelude for 12 months. It is fitted with a H23A2 engine. The Main bearings have worn at 126000 miles (full service history, oil change every 6k).
I have options regarding the repair but seek advice on the following

I can buy a H23A1 engine imported from Japan, The supplier has said that there is no difference between the 2 engines. Is this correct?

According to the Mitchell CD the bearings are colour coded at the edge. Main bearings from the Honda dealer are £19.50 per shell. I have been offered non genuine bearings for a fraction of this cost and the supplier says that the colour code is not necessary, anybody tried non colour coded bearings.

The Mitchell CD gives bolt torque settings for all bolts but has not given the torque for the main bearings, anybody have these figures.

Any help/ advice would be gratefully accepted

Thanks

 

Hello,
the H23A1 is exactly the same as H23A2, differences seem to be pollution control..
for the bearing the only thing i know is OEM bearing are colour coded for a good reason, they cannot be swapped over. Given the price of the pieces of hardware versus the man-hours of work i'd get OEM bearings...

there's your first problem.

I wouldn't trust anything from a mitchell catalog.

You can find h23 longblocks for around $1100
if you need a complete one.

 

also to note, h23a1 is a usdm motor, there were no h23's in japan, only f22b i believe which is almost the same and should still work as easily as swapping another h23 in, but u'll have to double check and search around for f22b to be sure

 

Thanks for the quick reply.
Honda bearing set in UK is around £350 sterling imported H23a1 engine £780.
Following your reply still deciding which way to go
Regards

 

Thank you for your reply.
Unfortunately Mitchell CD was all the technical information I could find.
Can you suggest something different
Regards

 

Thanks for your reply,
Interesting to see that the import I am offered is a US version not japanese as I was informed.
I have searched for the f22b engine, it seems to be a possibility but cannot find one in the UK
Regards

 

if you have the money then just take the oem bearings out without mixing up top for bottom, and the color codes should be on them.

if you want the do have a a one size fits all type from companys like ACL and they are cheaper , but OEM im my opinion is higher quality.

also if your looking for an engine swap, basically any F or H series motor will bolt in but depending on which motor may or may not require wiring modifications.

 

Torque spec for main bearing is 75 Nm.

 

yes, definitely stick with oem bearings they are of top quality....worth the money

what he is suggesting on the oil change interval is probably 3k like most do here.....not necessary with the synthetic oil were using now, but the way most of us drive..aka hard..it is a good idea to change the oil at a smaller interval.....

good luck with your rebuilding....

im sure that it is in kilometers, as he is from europe. but that still seems high

 

uhh why don't you upgrade and drop in an H22a?

btw as others have said an H23A1 would be from North America...it was never in a Japanese car...maybe some other export countries but not Japan...

 

maybe hes talking about the h23a that comes in the accord r wagon. dohc vtec ring any bells? around 220hp....

That would be H23A VTEC, no 1 on the code.

Unfortunately swaps in Europe are more or less prohibited (depending on the country). In my country it's strictly *verboten* to touch anything on a car (even rims) so i'm "illegal" with my CAI and exhaust for example.. so imagine a swap

 

What a great bunch of people, The amount of help and advice i have received in 24 hours is phenomenal.
As stated I bought my Prelude 12 months ago with 104000 miles recorded, it was registered in the UK. According to the supplied service record the 6000 mile oil change was from new and I carried on the practice. Being a young senior citizen I don't drive hard, speed cameras and police radar are becoming more intense in the UK, but I will change the oil change to 3000 miles and take oil samples to see the difference.
I have found some non OEM bearings for 20% of the cost of OEM, may give them a go until my son takes over the Prelude next year we can then pool resources and swap out for a 2.2 VTEC.
In the UK you are allowed to swap engines and modify your car, but you have to inform your insurance company and the cost escalates dramatically.
Once again thanks for all your replies, hope I can be of similar service sometime

 

Haha you don't have to tell the insurance company anything...they would never know...how many people at the ins comp would know the visual difference between an H23 and H22? Not many, if any.

£19.50!?! Hell go to http://www.hondaautomotiveparts.com (USA) and you can get them for about £4.80 a shell. Just ask them if they will ship to the UK. That is 25% cheaper than the UK and still OEM. Color codes and everything for the Honda reliability.
