Honda4LifeB18C

I got a civic EG with a B18C swap. It says 97' on the engine. I don't think its a GSR as the intake manifold is not curled. It has apexi vtec airflow controller, VTEC is set to kick in at 5200RPM. As I got this small device it also keeps live revs and the max the engine can rev if im not mistaken is 865*RPM or 85**RPM. I really thought it was a JDM motor. My hatch is Japanese 1992.

I believe that my engine is Type-R as GSR I think that it's rev limiter is 8200RPM and my EG revs up to 8500+.

I'm not sure if it's JDM

If it's stamped "B18C" then it's jdm itr.

dpine

Thats not true. Japanese engine codes don't end with numbers like they do here. The B18C could be a Type R motor or GSR motor.


OP, whats the stamping on the Cylinder head?

dave7

Ok that's interesting, I did not know that.

If stamp on the head says P72, then it's a GSR. If PR3 then it's an ITR.

dpine

OP,

On the front side of the cylinder head above the middle exhaust ports there should be a stamp. It will either say P72-X or PR3-X (X = a number)

P72 = GSR
PR3 = B16A, B16B, B18C type r

Since this is a swapped car who knows if its an ITR motor without opening up the engine. Chances are its running a chipped OBD1 ecu and not the factory ecu.

I have some pictures of my car on here

also was there ever a 1997 JDM ITR ever made?

on the logbook it says the engine power is 1799cc

Based on your pics I think you have a 97 or 98 JDM Integra Type R motor. There is a rare chance that you have a JDM GSR motor that has been swapped to a Type R head or B16 head also, but that seems unlikely.

They made the ITR with PR3-X head stamps as early at 1995 in Japan, so a 1997 head stamp is not uncommon.

Damnit you guys are right. My bad. PR3 on a B18C block would be an ITR engine.

that's good news, I don't know why I can only find very few information about 1997 JDM Integra Type R. Most searches that come are JDM ITR 96,98 and the 2000 or 01 model.

JDM 95-97 are the same. 98+ things started to change. Some might say for the better but I'd argue Honda went sideways, not forward. Take your pick as to which you prefer.

To my knowledge the only change between 95-97 was that the later cars had machine polished heads instead of the hand polishing of the earlier cars. All 98+ cars were machine polished.

The reason is that the 96 spec-R came out in 1995 as a 1996 model, so by the books there is a 96 spec-R which encompasses model year 96 and 97, then there is a 98 spec-R which is 98 to 01. Because the 96 spec R came out in 95 some motors will have a 95 stamp.

The machine polishing came about in late 96 actually, only the very early motors were hand polished. The 98 spec has a better exhaust manifold, has a revised ECU map, and better injectors supposedly. I'm sure there are other minor improvements as well.

The JDM 98's got revised spring and damper rates, thicker stampings on some suspension components, thicker antiroll/sway bars, 5 stud 16 inch wheels, larger brakes, different gear ratios and HID lights. ABS, Airbags and parcel shelf which had been options on the 96 spec cars(though the majority came with the parcel shelf) became standard(though could all be deleted when ordering). They also came with Vogue Metallic Silver as a colour option on top of the existing white/black/red(wheels could also now be ordered in dark grey). In 99 Phoenix Yellow was added to the colour options(with the option of Yellow Recaros). The 99 on to the end of production was the Type R-x. This was a fully optioned 98 Spec with added extras like a (Gathers?)radio and extra speakers and dash clock as standard, blue toned faux carbon fibre trim, metal "sport" pedals, tinted rear quarter and hatch windows, retractable mirrors and keyless entry. The R-X was the only JDM R to come with a serial numbered console badge. Mechanically they were pretty much identical, though drive shafts were balanced. These were the heaviest of the JDM Type R range.

Thats just the JDM R's, the list of little differences and special editions from the rest of the world is another day's work.

How did Honda go sideways with the 98 spec R compared to the 96 spec? If anything all the changes were improvements.

feck

I suppose it might be argued the 98 spec is less raw than the 96 which is the original of the species. Heavier too in standard trim(though customers could option delete all the extras so the weights would remain about the same). A minor thing that I can feel on the road are the 16 inch wheels. I have a set of both the 98 16's and EDM 15's. The 15's of the 96(and the US/EDM) give a better feel IMH and are less prone to getting unsettled on uneven road surfaces(cheaper tyres and more choice too). By the time of the R-x it had started to get a little more bloated and heavier again. There is little enough if anything in it for the vast majority of drivers and the extras make for a more liveable and safer car(ABS/SRS). Either way all Integra R's were and still remain extremely focussed drivers cars.

Tom B

I knew I opened a can of worms with that comment. I guess it depends how you define improvements.

I'll leave it to the others to discuss as I'm not interested in what I fear might become a 96 v 98 debate :-)

Understandable. Not looking for a debate. Is there an actual difference in the motor besides the trans? Can't seem to find any solid/credible information on this. I believe header and cams are different, but not sure what else.

Tom B

There's a good amount of information in the Best Motoring videos which can be found on YouTube. IIRC the Spoon CEO talks about the differences.

good place to start.

PaulMc

Seen them all. From what I gathered the 98 spec out performs the 96 spec in everyway. They don't get too specific about engine changes.

Tom B

It seems that way. Although, IIRC there was no outright performace advantage on a small circuit. Also the drag times are the same with the '98 Spec being a little quicker off the line but the '96 Spec catches up in 4th gear.

dave7

This is why I think putting the 4.7 FD in a usdm itr trans would be ideal. You'd have the shorter FD and the shorter 4th and 5th. That's what I'm going to do.
