I wanted the NonVtec fans to give their two cents on using OEM parts to improve performance to their B18 engines. For example - injectors from the b20 to the b18 to improve fuel. "Not sure if that's true but heard it somewhere". Or, "CR-V calipers to add extra breaking". Let's see what we can pick up on a tight budget.

uh, all b series injectors are the same even type R

you should look into calipers fron an accord v6 or accord wagon

airbox / intake tube from sonething with a bigger engine, maybe a v6 something.

header from a GSR

thats all i can think of, not a whole lot interchangable...

Honda-tuning had an article once on putting twin piston calipers from an acura legend on a civic and I had a friend try a five lug conversion for 1/3 of the cost by using prelude parts. Thats all I can think of unless you're getting into the motor then you have a plethora of parts to upgrade with; from pistons, and crank swaps to cam and entire head swaps.

theoldone.com has a write up on to use a ITR intake manifold on your LS/b20....

i have the legend calipers. you've gotta grind 1/4" off the mounting bracket for clearance for the rotor... then you've gotta use 92-96 prelude vtec rotors becuase they fit without shims or anything. these put you at an 11.2" rotor where as stock, i think is 10" or so.

you can use 02-04 si rear calipers and rotors on your 94-01 integra as well as 90-93... they're 10.2" where as stock rears for itnegras were 9.2", i think.

I like! So I can get my buddies stock header from his 95' GSR and put it onto my 90' B18A1? Increase power?

^ The only issue you'll run into is fitment to the rest of your exhaust. GSR headers/downpipes are quite a bit longer than DC LS headers/downpipes, but otherwise everything bolts up. I had a manifold and downpipe from a '91 LS on my car once, and also had a '96 GSR mani on it for a day, everything bolted up. I have a head from a '93 GS on my B20, btw.

Hondas are Legos, haha.

you can use an ITR intake mani huh, how many type R's you see in junk yards lol

the legend calipers are good, they are an upgrade even over typer/accord v6 ones

thats some good info bout the SI calipers for the rear, never knew that.

well by ITR it also means B16 s well.

i have a set of the calipers but im not sure if i wanna sell or not...

yea, i ran across a thread on honda-tech about the 02-04 (4 lug only, you dont wanna have to redrill a 5 lug rotor, i think the 02+ rsx's will work as well, but sure.) i was amazed. im hellbent on doing it.

About the GSR header.... I don't think I am going to go with that. It has a lot of weight to it. And I don't think it's going to be that big of a hp increase. But what about more engine "lego" stuff? I do think I want to try and find an Intake Manifold from a b16. I bet that would be a nice little bump. But would I need to worry about the TPS on the TB? Or would I still use my TB?

You can use all your stock electronics/sensors as well as your stock throttle body. B16 throttle body is the same as an LS anyway... A GSR and ITR TB is bigger, not sure sizes I think its 60mm and 62mm... cuz LS/B16 is 58mm.

newer LS tb's are 60mm just like gsr's

Cool man, TY. Wanna beer? I'll email it to you.

What about cams, pistons, valves, and springs? Anything from the B20 an upgrade?

Cams - crower 404's
valves - ferrah, supertech [if they make em for an ls]
retainers/springs from supertech [if they make em for an ls]
pistons - p30's

Using parts from a B20 as an upgrade... absolutely not.

I see. So if I had a B20, and wanted to use parts off a B18 (internals, IM, Tranny) that would be an upgrade. But not the other way around.

the b20 and b18 have two different bore sizes i think the ls is 81mm stock and 84mm b20 nut not 100% i just know that they are different

is there anything you can do to a B18A that would give it more tourque from a B20?

No but if you have a B18a and a B20B or Z you could use the water pump and timing belt because they are the same as the Vtec on all the newer B-series. Thats what I'm doing. Aside from boring the B18A out and using the B20 pistons there's not much internal you can do

What?

No they're not.

Part number for the timing belt from a 2000 B18B1 (B20B/Z, as well) is 14400-P7J-004 where as the timing belt for a 2000 B18C1 is 14400-P72-01.

The part number for the water pump from a 2000 B18B1 is 19200-P75-003 (B20B/Z, as well), whereas the water pump for a 2000 B18C1 is 19200-P72-013.

The LS water pump only has 19 teeth where as the GSR/ITR/B16 have 22 teeth. Im sure the exact dimensions or teeth count on the timing belt, but I do know the LS/B20 is longer than the GSR/ITR (B16 possibly).

What about the valve cover? The B20 valve cover looks better than mine. Could I use it without any problems?
