All motor... go lsvtec. The head flows much better and good for better all motor power. I like skunk 2 parts, a little expensive but worth it IMO.

This article might help:

http://www.c-speedracing.com/howto/nabuild/nabuild.php

-Also, check out ITB's "Individual Throttle Bodies"...they're expensive, and i've heard you need an aftermarket Engine Management System to run them...you could use performance camshafts, high-compression pistons, performance header, performance intake, etc. Just depends on your exact budget, and power-goals.

I agree. Ls vtec is good. Most ppl just go with a b16 head and a comp. If you change your mind go ls vtec. But use the gsr head for more compression. Also it good if you change the pistons. From what i hear type r pistons are the way 2 go.

i absolutely hate ls-v unless it's done right and by that time there is usually little to no cost savings over a C block. $1500 gets you a jdm sir-g aka gsr engine. sell what you have, buy one of those, install and go. doing a build is going to eat up time and cash. you'll have the ecu, tune time, hondata, parts like cams, pistons, VT etc. to actually make LS-V reliable you'll be buying aftermarket rods, paying to have them sized, spending a couple hours measuring bearing clearances and having a line hone done if need be to bring them into spec, and or buying honda bearings in different sizes.

just for fun lets do a little write up

obd1 ecu $100
s100 $199
tune time $250
used itr or skunk1 cams $300
scat h beam rods $300
used vtec head $300

we're already at the price of that jdm gsr motor and we have no bearings, no gaskets, no machine work. no idea what shape the often worn out LMA's are in with our used head. no clue on the valve guides or seats either. you also have to ask yourself what your time is worth. a gsr motor is a one day job at most and there is no weirdness with tuning. you wire in a p72 ecu and start the car

I'm not a fan of LS-VTEC either...i've always told people to just get a GSR if they want VTEC rather than wasting time and energy converting one...I like your post, well said.

I wonder if things like the LS/VTEC head swap are common for a reason...? Maybe because the alternative (building an LS head) is needlessly expensive and doesn't perform. By the way, who really cares if you have an LS/VTEC and someone else does too...nobody is going to be impressed by your straight LS, but rather the results of your build

i never see jdm gsr engines for 1500, i hardly even see oem gsr engines for that price, last one i saw for 1500 had like 140-150k on it

The only downside to an LS/VTEC is when it is improperly built. People complain that they are unreliable; however, my LS/VTEC was built properly and runs just fine. If you plan to use stock rods (whereas i have Eagles) then upgrade to ARP rod bolts. If the rest of the setup is built to spec correctly, you should have NOTHING to worry about

The reason a GSR engine would beat an LS in reliability is because when you buy an OEM engine, you know it was assembled correctly and to spec. If you can afford to go this route, it is much easier; however, on a budget, an LS/VTEC is a great alternative

there are two jdm engine shops that aren't too far from the OP, one is

the other is

over in richardson texas. if you pick it up in person knock at least a couple hundred off

You would still need to get an ECU and a new wiring harness. Its engine only, nobody wants to run a GSR engine with an LS transmission... The site says add another $700 for a transmission.

So:
$100 for ecu
$100-200 for wiring harness
$700 for transmission
and $1800 for an engine
You're still looking at just under 3 grand.

Its not that hard to build an engine the right way. When you build it yourself you get more satisfaction knowing YOU built it. You can make the engine the way you want it, High compression/low compression. Most of the time the reason for an Lsvtec is more expensive is because people don't just stop at all OEM.

I think if done right the LS/VTEC is the way to go..

transmission is irrelevant. sure the gsr transmission is a better performer but it isn't necessary. creating an lsvtec assumes he will have the ls transmission right? the gsr isn't going to perform any different since power wise they are extremely similar assuming he uses a stockish cam in the build. just buying a jdm gsr saves countless hours of your time and 90% of the time you'll be money ahead versus doing a build. the ecu and harness are of course needed. but wiring will also be needed with the vtec conversion on the ls, same with ecu work. with the gsr you have a reliable and cheap way to go. it's really not hard to spend 1000 just rebuilding a cylinder head

oh we can do better than that, here's $2474 shipped with the engine, tranny, ecu, everything.

http://cgi.ebay.com/ebaymotors/Integ...#ht_3656wt_939

i've also bought 2 engines from these guys and both were in excellent condition

the other thing going this route does is increase resale. 99% of the time any buyer will feel more comfortable buying a stock jdm honda swap over a "custom built ls-vtec" the exception to this is a documented build with all parts, clearances and everything done correctly. this of course means lots of money on parts and on machine work, not to mention the countless hours of your life.

he does have a point there, if you do plan on reselling the car, a buyer is going to feel more comfortable with a complete swap rather than a frankenstein set up, unless you have receipts that it was done at a shop, most people wont touch it. Thats IF you plan on selling your car
