Elkins911

can you make this a sticky thread? i like looking at the pics.

satan_srv

It's in the FAQ

mattmw88

where did you find all these pics? I knew that Japan got all the goods cars, but never to this extent. I'm moving...

donz

Which engine do you guys feel is the best for mild N/A applications? I assume they all weight the same.
Also do you guys have any gear ratio information on the F20B? does it have LSD?
I'm looking for one of these to go in my civic, but i don't think i can afford the type s

damn those japsanese they want to keep all the cool cars for themselfs

satan_srv

added gear ratios. Also added a really cool euro-r vs. type-r accord power comparison.

MotegiMan

Not sure if people are interested but here in the UK there is another Red Top motor, as fitted to the 1999+ 5th generation Prelude Motegi. Engine is the H22A8.



As far as I am aware it is the same as the Euro Accord Type R engine, however no port and polish.

I have a '99 Prelude (Euro model, I'm from Italy)
It's a normal 4WS and I can confirm that my engine also is the h22a8, wich is the only spec available in Europe since 1999 (with manual tranny).
Obviously the valve cover is red.
You are the one guy I've found with the same engine as me (the best for Ludes)

would anyone happen to know the differences between a H23A vtec and a H23A1 non-vtec? need any info thanks

Yeah a VTEC head. And the block is newer and open deck.

MotegiMan

Just thought I would add a little piccy (See my previous post) of the H22A8 for any body interested...

From hunting around other web sites etc... I get the impression that the air intake on the H22A8 is the same as that on the Type S. Can anybody confirm or disprove that?

It's the same intake as JDM Type S. Please check this link

Look at the weight savings! In just this one pic you can see that they used a Civic Battery (20) lbs savings right there... And the Aluminum Motor mount on the Driver side... I have been thinking about making Aluminum mounts to shave some weight off the front end of the car. Need to shave some weight off the front end.

wow nice info

Weird...but it only has 200hp?

Can you read the P5* code off the head? if it says P5P it should be a type-s head. Or does it have type-s cams.

Can you read me the tranny code as well? It's on the label by the engine code.

I went outside and had a quick look under the bonnet (its dark down there in the office car park ) and the only P number I could see was P13? (Just above lefthand side of manifold) but this does not fit with the convention you mentioned so I guess I must be looking in the wrong place?

Similarly what format should the transmission code be in? and where should I be looking. Forgive me I am new to this!

I am happy to go out and retirieve any of the codes for you, as I am keen to understand more about this particular engine.

One of the previous posts asked weather I knew if they were Type S cams or not and the answer is I don't know, however I imagine there will be a code stamped somewhere, so if you point me in the right direction I will retireve it for you guys.

Any other questions about this engine/car just let me know as I am happy to go and get piccys etc... (New digitial camera beggin me to use it )

ATR and Motegi share the same engine but Motegi didn't get p&p, so here's burried the power difference.
What funny Motegi is quicker than ATR because of weight difference: 1319 kg vs 1405kg.

Motegi: 200HP@7100rpms, 212Nm@5250rpms 6,9s 0-100kph Vmax 228 km/h
ATR: 212HP@7200rpms, 216Nm@6700rpms, 7,2s 0-100kph Vmax 228 km/h

I have a nice write-up about those cars but it's in Polish...

MotegiMan

I believe they are two different engines, Motegi engine developed from ATR engine (H22A7 I believe). There is more differences than just the port and polish. I belive differences include: different intake manifold, cams, vtec timing, maybee even the pistons etc.... I am assuming the cams are selected to make optimum use of the better flow of the head.

I have had the pleasesure of test driving an ATR and the power delivery is slightly different. The Motegi VTEC change over is at 5500 rpm and you need to rev round to 7500/8000 rpm before changing where as the ATR is later at 6000 rpm and you need to hold the revs until 8000+ rpm. ATR pulls a bit harder in VTEC and sounds awesome.

Car is definatley heavier due to additional bracing for stifness etc... and is slower in a straight line, however I would say the handling/grip(due to LSD) is better.

If the article you are talking about is the one from car magazine I have it in English. I will scan it and post it up at some point for people to have a read.

Possibly there are more diffs. I haven't met Motegi model so far :/
Yes, this article comes from April 1999 Car Magazine and is written by Mark Walton.

no you did it right..that's why it's confusing. P13 is the head from the 4th gen prelude. Why are they using an older head on a newer car? It definitely doesn't have the P&P if they are using P13 heads.

The tranny code is on a sticker with a bar code on in which is viewable from the front of the engine bay. It's right by the starter where the tranny meets the block near the flywheel/timing window. It may be partially covered by the lines from the slave cylinder.
