If you're not sure about maintaining a turbo system, you really don't want to attempt a junkyard turbo setup.

If you want to avoid machine shop work, then you really can't do anything inside the engine. Porting, new pistons- all of that requires machine work. Without it, all you can really do inside the engine is replace the camshaft. Everything else is external and gives minimal gains towards your 50% goal unless you want to go with boost.

A new fuel rail and injectors won't help you at all because they're not really performance adders. They're used to extract more power from parts that increase flow through your engine. Without the extra airflow, extra fuel can't be burned. You can optimize your tune a little bit compared to the factory setup without power adders, but you'll gain a few percentage points at best. ]]> Engine Building Calesta http://hondaswap.com/engine-building/d17a2-build-advice-421133/ <![CDATA[thought I'd find this discussion on here]]> http://hondaswap.com/engine-building/thought-id-find-discussion-here-420500/ Fri, 20 Nov 2009 04:56:53 GMT heres an exhaust you could put on itImage: http://carphotos.cardomain.com/ride_images/4/203/4521/38007260484_large.jpg heres an exhaust you could put on it

They are coated on the skirts but I don't know if it will raise the comp too much with the B18 head.
I took the rings off and it slid in the B18 block nicely, with little resistance.

I need to put them side by side and take a pic. I don't have the barretts or know how to measure the volume of the dome with it pokin out the top of the bore.
I wonder how much could be milled off the crown of the piston??

Just because they slide in dosent mean they are perfect, your piston to wall clearance should be at OEM specs or of the piston! if not, you will destroy the walls and skirts if they are too tight, if they are too lose you will get way too much blowby and destroy your engine. No good machine shop should bore and hone your block without the pistons your going to use. ]]> Engine Building Magana559 http://hondaswap.com/engine-building/b18-b20-combustion-chamber-welding-411202/ what camshaft should i get http://hondaswap.com/engine-building/what-camshaft-should-i-get-415343/ Mon, 16 Nov 2009 22:01:22 GMT After you get the head off, pull that little oil restricter out so you can clean under it. It might have crap behind it. Even if you have a 'cradle' that holds your main caps.
(I had an old 1200 that I pulled the plugs in the ends 'just in case', and man was it loaded with metal shavings! Good thing I listened to GOD.)

I wouldn't trust that block. I know it's a pain but you could ruin the motor in seconds if that crap is still in there.

Honda cranks are pretty stout and usually don't give up that easy. Have a good pocket porting on the head with a mild cam. Have your injectors flowed by a reputable shop.

Once you build up a good bottom end, you will be less worried about it later when you add more stuff to it. (you know you will..)

Most important thing is keep it all CLEAN when you build it and if it will sit for a while, Bag it up. You don't want to disassemble it, re-clean and reassemble again.

Check under the dizzy cap, does it look like red dust covering everything? ..(It shorts out and messes up the firing order.)

Take a look in toward the throttle body opening. Is it all 'gunked up'? If so, clean. The carbon/sludge keeps the butterfly open)

Check your grounds. There might be some that are not there or missing.

i have a 90 civic si with the d16a6. I purchased an exospeed reground stage 2 cam and an aem adj cam gear. I replaced them a year ago and haven't started the car yet. (wainting to paint the car). Now that I'm trying to get the car running, the car won't start. I remember having a hard time when I replaced them becasue the old stock cam gear has the notch for tdc. But the new gear didn't have it.

Anyone out there know how to get the car timed right. I checked my firing order, and reversed the distributor thinking it could be 180 out. But still nothing. I do have spark and have replaced the plugs and put new gas in it (parked it with fumes). I also tried using starting fluid. Not even a sputter. My only thoughts are that when I installed the belt the head wasn't in tdc (the bottom end was at tdc #1 cyl).

How do you know when the head/cam is in tdc?
