ninet4teg Posted April 19, 2004 Share Posted April 19, 2004 ok before i waste my money and time i want an honest opinion on an ls/vtec swap, how good are they and do they last. i have read if it isnt done right the engine will blow and it if its done correctly they are only good for around 30k? PLEASE HELP!! Link to comment Share on other sites More sharing options...
carta79 Posted April 19, 2004 Share Posted April 19, 2004 The reliability of that swap is always in question. I have heard horror stories about it and I have heard good things about it. If it was reliable I would think Honda would have developed an LS Vtec from factory. Personally that swap is not a chance I'm willing to take. If I were to spend my hard earned dollars on something I would need to be 100% sure it's worth the money. Reliabilty is one of the very things that attracts Honda buyers in the first place. I would save my money for a GSR swap if I was in the market to do such a thing. Maybe SSR will post his opinion on this matter. I don't know if he's for or against this issue.

BigBirdSucks Posted April 20, 2004 Share Posted April 20, 2004 the biggest mistake most people make when doing an LS/VTEC or CR/VTEC type swap is using the wrong rod bolts. ARP rod bolts are a must for that setup. Link to comment Share on other sites More sharing options...
Mercutio Posted April 20, 2004 Share Posted April 20, 2004 Honda did make an LS/VTEC...it's called the Intega GSR. B18B displacement 1834cc B18C displacement 1797cc Close enough for the risk involved with an LS/Vtec conversion. I would agree with just getting a GSR engine and working off that.

..SSR.. Posted April 20, 2004 Share Posted April 20, 2004 It is reliable if you build it right. Get good rod bolts and torque/stretch them correctly. Honda never made an LS/VTEC. The B18B has an 89mm stroke while the B18C has an 87.2mm stroke. With the 89mm stroke, the engine can rev to 10,500 RPM if using aftermarket parts, but not for long. If in a long road race, the engine would fall apart rather soon, hence the 87.2mm stroke in the GSR, longevity. A fully built N/A B series on pump gas can last around 20,000 +/- miles. Omniman created the first LS/VTEC. He just dropped a B18C1 in a customers car then the engine blew. He felt bad so he started comparing parts with a B18B block he had lying around. Everything matched up with a little work and just the head on the block pulled harder than the stock B18C. He then put ITR pistons in it followed by cams and it made 180whp, impressive for that time. Any built engine won't be reliable. Drivability comes into play when you get cams. Do you want nice power, nice idle, and nice starts. Or do you want a rough idle "camming", awesome power, and crapty ass 3,000 RPM to get moving starts? Link to comment Share on other sites More sharing options...
S14Silvia Posted April 21, 2004 Share Posted April 21, 2004 they last...:-" if you're honestly wanting to do an LS/VTEC make sure you spend the money to do it right! i personally wouldnt waste time and money building an LS/VTEC, just go turbo or build up a n/a gsr motor -_- Link to comment Share on other sites More sharing options...
ninet4teg Posted April 21, 2004 Author Share Posted April 21, 2004 i really appreciate all the information you guys are giving out, i would like the car to be as reliable as it sits just as an LS right now but just be able to have the GSR head on the car with the same relieability if at all possible. i have been in talks with a local guy who does all honda work in my area and i trust he can do it right and going along with what SSR said i would like hte nice starts and still havin the low end torque of the LS and the mid to high range power of the gsr. i am beginning ot think of just swapping out the entire engine to a GSR like some have suggested?

ninet4teg Posted April 21, 2004 Author Share Posted April 21, 2004 just a figure i would like to have, if it is done "right" what am i looking to spend parts and labor? Link to comment Share on other sites More sharing options...
Mercutio Posted April 21, 2004 Share Posted April 21, 2004 If you already have the B18B block, than it wont be TOO much. You can get a stock GSR head for relatiely cheap, compared to a whole swap... Link to comment Share on other sites More sharing options...
..SSR.. Posted April 21, 2004 Share Posted April 21, 2004 Parts, depends on what all you get. Labor should be no less than $600 for engine assembly if done right. Link to comment Share on other sites More sharing options...

S14Silvia Posted April 23, 2004 Share Posted April 23, 2004 i dont have much lag.. but then again i have a fairly small turbo and its dual ball bearing. t3/t4 will have lag, the t28 should have minimal turbo's make gobs more torque then n/a, plus higher hp.. cant go wrong there Link to comment Share on other sites More sharing options...

optional187 Posted April 23, 2004 Share Posted April 23, 2004 lag shouldn't be that bad. my lil' t25 spools damn quick, even in 5th at cruising speeds. t28 would be a little slower. a lot of people knock turbo's because of lag, but i actually like the feeling when you can hear the turbo spooling up then the car lurches forward with the added power. its nice.
