i just bought a 99 GSR and when i got it home, i popped the hood again and found a B16A2 block, and a VTEC B18C1 head...i was dissapointed at first but said who cares and kept it anyways...

now, my question is...is this a good setup???...should i change the head back to a B16A2 head??...or is this B18 head better??...

i just dont know much about this stuff yet, thanks for the help

I believe a b16a2 head flows better than a gsr head, but if I were you id try to get a 1.8 block(gsr,ls) on there... that extra torque would help move the beeftron of an integra more than switching the head...

JSPECEX

get a ls block better compression a little faster and cheaper

Thats a long lived debate. With the GSR head the compression will be lower then with the B16A2 head. Personally, I would go with more displacment, depending on what you are putting the engine into. I would also talk to the person you got it from and look into a possible partial refund.

OT: how could you not be pissed at this? was the price cheap enough that you don't care that you purchased someone elses problems if there are any?
who built the motor and why would they replace a b16 block over a b18?

I`d go back to where you got it, bust the guys *****, and get a new block FREE.

I`d be furious

Wut u pay for the car??? Crappy deal in my opinion unless you got it cheap! Also, just suggestion but have the block numbers run to make sure its legal!!! Good luck. I too say, go bust some ballz. Once again depends on how much u paid$$$

Sucks that you got ripped off. Well i say sell the b16a block and buy a B20 block and beef it up.

tmekjian

well i paid 8 grand and i got a 98 GSR with the b16A2 block with 29,000 miles, and the B18 head with 55,000 miles...

also coming with the car was brand new DC header, COMPTECH intake, COMPTECH exhaust, cheap ebay Front Strut Bar, and DC billet lower rear tie bar, coilovers, and bad *** 17" wheels...

yes, i have ran the VIN's and checked everything out, the block and head are both 99's with low miles and compression is good...the car looks beautiful...i will post some good pix in an hour or so...

tmekjian

here are pix of the car...now tell me that it isnt beautiful...

I hope that's suppose to be a joke. That ****'s funny...

tmekjian

it was, and i am glad that it was taken as such

tmekjian

so my next steps should be cams/cam gears/springs/retainers???

should i worry about changing the intake mani if i am sticking with relatively mild cams like the ITR/CTR cams???

remember, like most people i dont have 10 grand to dump into my engine, a couple hundred, or 500 at a time is more like it...what other options do i have???

What you should worry about is the fact that you got ripped on the car. How can you not care that the motor in there isnt supposed to be in there, and that you werent told about it?

Jonathan_ED3

with a b16 block, wouldn't that be losing a substantial amount of power?

00b16

Its not too bad of a deal for that car. I say go ahead and find a gsr block then sell the A2 to someone. Maybe toss some new pistons in the gsr block ITR and call it a day for the bottom end. Then cams and find a way to tune or get a chip. Done, then just drive the **** out of it. (Maybe a clutch too). Good luck.

tmekjian

so instead of just modding the block and head that i have...

you are all saying that it is imperative that i change the block???...i dont see how spending all the money on changing the block is better than taking that money and working with what i already have...if i spend the money to change the block i will be out of money...

someone give me some more advice...this is a serious decision i need to make...

1...spend the money to change the block

2...spend the money to work with what i have (B16A2 block with B18C1 head) if i kept my block i would probably put ITR cams and valvetrain in, and maybe do some piston/compression work...

thanks for the help

tmekjian

also, i thought a B18C1 only has 10 HP more than the B16A2...

if i have half of each engine arent i pretty close to either one of those???...i guess i just dont see the point in changing an entire block...

but if it is the most important thing to go faster...than i guess it will have to be done...let me know...thanks

MikeMAN

its not really about the 10hp, its about the torque that helps to get the boat movin'

mike

NiiS

Night and day difference...Although you could stroke that bitch...Check around, I know a friend is *suspected* to have this set-up and it made damn near the same numbers as a JDM ITR on the dyno, of course he won`t actually say what he has done, we all conclude this is the case

Drag_On

Just build the **** out of a B20 block.. It will feel better than putting bolt ons into your bybrid motor you have now..

tmekjian

help me please

Black 2K

have that ***??? wow mann

anyways... i think you are the only person i have seen with a B16 block and a p72 head... seems kinda weird. Sonds like the guy had some extra stuff laying around the garage and decided to just throw it in... There is nothing wrong with the head... Both of them are success, like it has been mentioned there is debate as which one is better. IMO honda went with the PR3 for the itr so i will go with the PR3 head. But the B16 block is a B16 block... I just think it is kinda weird to see that combination of block and head.... Becasue if a person has a B16x and wants to upgrade... he is not going to get anything out of a P72 head over his PR3... If anything minimal becasue the cams might be a little better assuming it is a complete head. But you change the block... not the head...

Drag_On

OK-- You want help -- here it is..

It is NOT imperative that you change the block.. Your car ~could~ have more horsepower than a REGULAR GSR block because the B16A2 has higher compression.. It will have LESS torque due to the lack of displacement... It is absolutely NOT imperative that you change the block.. It can ACTUALLY rev higher than the stock block safely.. Your just going to be lacking the torque found in a GSR motor.. Its OK-- but like we've all said you should at least ask for some money from the guy.. The GSR block is worth quite a bit more than a B16A2 block.. Your car is FINE though.. Build a B20 block for AWESOME torque and still the ability to rev... Just my .02

-- uh, how much did you pay for it ? if you paid the price of B18C engine, you got RIPPED OFF.

[edit]
Just read the whole thread --&gt;&gt; HOLY **** YOU GOT JACKED!
$8000?! ARE YOU ******* KIDDING ME?!!!

[edit edit]
Ok, misread that, so you bought a full blown GSR w/a B16 motor in it, very shady.

now, my question is...is this a good setup???

-- besides the possible rip-off factor, this is actually a good setup w/a Skunk2 manifold. The GSR head makes some pretty good low end power over the PR3 (b16) head, not to mention your compression will be raised a couple clicks. Since you own a 'torqueless wonder' (B16 slang), the GSR head will help you in the torque dept. I say try it out, if you don't like it, sell /trade it for a B16 head.

...should i change the head back to a B16A2 head??...or is this B18 head better??...
