Does anyone know why the 90-91 tegs made 10 hp less than the 92-93s? I need to know before I buy another engine to build for the race car. Were the heads different? Please help!!!

as far as i know the diffrence is the cams and the exhaust manifold.That is where they say the extra 10hp comes from,you know you could always try a SEARCH
If you’re buying another engine, I’d suggest a B18B. 142Hp, a bit more torque, and just a nicer overall engine (i think) 
if u buy a newer integra engine and keep your orignal computer u will stay at 140 hp the newer engine have 142 hp because the computer is different.
I wish I could go with another engine but the rules don’t allow it. (I race SCCA ITA) So from what you guys think, if I can get a 90/91 engine and replace my cams, I should be right back at the advertised 140. (right?) I’m already not using the stock manifold. I was concerned that the internal runners and ports were different b/n the years.
Welcome to the club.
Next timee please try seearching first.
im 95% sure its the cams and intake manifold.

your questions would all be answered if both of you did a search.
Not to be a dick or anything, but if you do a search on the word “search” alone, you guys will understand.
I’m pretty sure cause it’s the bumper style :), yea the way the mouth is designed u get better air to your intake hahahahahah
try :search:
I’ve heard the difference comes from camshafts and intake manifold. The distributor is different too, but I don’t think that counts. I believe there is also a second o2 sensor just upstream of the catalytic converter so maybe that helps engine efficiency???
Im pretty sure it also deals with compression…

nope.
I’m quite sure all LS pistons are the same.
Cough Cams Cough
Thanks for all the help guys! I did do a search and found good info. Sorry about not doing a search sooner but it seemed that most were vtec vs non-vtec threads. 
Anyway, checked and there are different part numbers for the two sets of years on the manifolds and cams. (stock part numbers)
90-91 parts:
Intake manifold: 17101-PR4-H10
intake cam: 14111-PR4-A00
Exhaust cam: 14121-PR4-A00
92-93 parts:
Intake manifold: 17101-PR4-A00
Intake cam: 14111-PR4-000
Exhaust cam: 14121-PR4-000
The heads are the same for both years. I did not check on the exhaust manifold but I’m sure they are different. I will try and see if I can find out from contacts at Honda for the engineering data on these parts and hopefuly we will know exactly the differences (i.e. the TRUE lift and duration on the cams). Either way, thanks for getting me going and again I apologize for not doing a more extensive search sooner.
I’m quite sure all LS pistons are the same.
nope they’re not all the same… JDM b18b has a 9.5 compression… USDM b18b1 has a 9.3 compression.
