I was wondering...does the GT cam fit right into the LX motors without mods? Cause the escortfocus.com cams are way too expensive! 8O And how much do you guys shave of the head? Even if its on the GT head? Has anyone ever tried the 25% underdrive pulley from EFP? cause it says it fits all 1.9L CVH. And do u think its worth polishing the head ports? thanks for anyone who can help.

I doubt either GT cam will fit in the LX... but if you have a spare GT cam sittin around... try it for fitment.

edit: I just realized you're more than likely talking about the 1.9 HO cam... in which case I do believe it would fit.

edit 2: I just looked up those cams on escortfocus.com.. you're saying 249-279 is way too expensive? The cams I'm planning on for the Civic are, at the cheapest I've found, 519 dollars.

because it would be cheaper to shave the head i got then get the pistons and the head off of a GT. Cause the LXs didn't have the dome type pistons like the GTs

The GT 1.9L HO cam will go right into your LX head just fine. I did that swap to my current LX about a year ago. In all the GT cam is only a small upgrade, it did make alittle difference in the power band, but nothing dramatic. I would not suggest spending much money on one, but if you can get one cheap and have some free time it's worth a little wild.

I got my cam for about $12, the install took about 2 hours, and can be done with the head still in car. If you would like a quick run down on what I did for the install, just let me know.

James, you know we are all cheap when it comes to buying parts. :wink:

no, its not that we're cheap (although $300 for a cam kit is a fair price), its that parts for the nicer Honda engines, although plentiful, are still EXPENSIVE.

^^I think you are right. If memory serves, he would lose a lot of compression if he swapped heads.

You'd have to change a lot of fuel system components, do some wiring, and change out the ECU to go to a GT motor entirely.

it takes a lot of compact rice to make steel... becides, cams are only going to give you like 5 ponies anyway. trust me i know more about hondas than you think...

but back to the topic.. why would you want to put a gt cam in amyway?if your going to go thru the hell of pulling both heads, just swap them.

It would be like doing the 1.9 block SPI head combo.

End result: Low compression good for turbo but not for N/A.

You don't need to pull the head to swap cams in a 1st Gen. Just remove the cam gear, distributor, and the battery (to make room). Then remove the valve/rocker cover, the rockers, lifters, and the cam thrust retainer. Then gently slide the cam out from the distributor side of the head. Do the reverse for the reinstall, reset your timing and wha-la. The whole cam swap takes around 2 hours, and over all I felt it was worth it.

Note: This is also a very opportune time to replace the cam oil seal, distributor o-ring oil seal, and for a little more work the timing belt, and check your water pump.

as far as putting a gt in a lx the wiring needed is 3 wires for the other injectors and the plug for the computer needs some wires changed around and added and taken awayand the computer changed
ive tried it to a 90 lx but thats a long story

It's a lot of work to put a GT head on an LX. I have an LX CFI, and it'd be crappy to replace the ECU with a GT or better one. I've got a "rebulit" head. It had a crack in the #3 comb. chamber, but it's sealed. The surface is milled as well, so compression is up. The block is also bored 1mm (.040") over to clear up a gouge. I'm not in the mood to spend a lot of money getting new pistons (just got new CFI style pistons two weeks ago) and rewiring the car. I know most of the wiring is the same, and the harnesses should hook right up, but what about the extra lines for injectors? Then there comes the replacing of the fuel pump for the EFI version.
Since I'm a poor man right now (living on 400 bucks a month), and I've got this thing finished, I think it'd be cheapest for you to just keep the LX setup for now, and go high compression. And go find a GT exhaust header, and a straight pipe. the GT header bolts right up to the base model head.
Also, if a GT cam fits, it might help some, but here's an odd thought. Would it be possible to bore out the CFI intake, and stick in a larger butterfly? And what about porting the intake manifold itself? And porting/polishing the head? I can't port my exhaust side due to where the crack was, but no biggie. I'll do what I can.
