OK, i now decided to not go turbo auto, and go with a k20, but the k20a3, cant afford that much for the a2, but IF U THINK U DIDNT SPEND THAT MUCH ON UR SWAP, I REALLY WANT TO KNOW HOW MUCH U DID IT FOR? OR KNOW ANY1 THAT GOT IT CHEAP?and another question, whats the differ in the k20a3, and a2???

yeah, you're better off saving up for the a2. I test drove a 2005 si and it wasnt that impressive compared to the d17. Now if you're planning on boosting your motor after the swap, I dont think going with an a3 would be that terrible of a motor to have (but thats just my opinion)

the topic should be how expensive instead of cheap. and what the hell why ping me about my turbo kit then change your mind..

Unless you want to boost later. Its built better for boost. I have a k20A in mine spent a little over 8, but then ive come accross some problems, like shattering axles and junk, So it was accually about 9. Lets just put it this way im up to $30,000 in my car, and i want more lol. Ill probalby stay NA, cause ill have to detune my engine so i can boost it. And if i boost it it going to be a supercharger :-D. Not shooting for top end any more. But if you want to boost ide stick with the A3 and theres one on Ebay for about 2500 right now with all you'll need. Minus a couple things.

Ide say save you money and do the laybor your self, although ive found several places around here that will do the install for about 700.

my current plans are about 6k for a full race turbo 400 for a tune on 91, 100 and c16.

4k to built it...

This is wut i've been saving/buying for my EM2
Block: k24a2 w/o tranny = $1,000.00 cash @ 6.5k miles (friends dads car engine ran but car rear/side frame ****ed)

Head: K20a2 or K20a (@ around $600.00) pending i need help on which is better for my hybrid.

Tranny: RSX Type S (local junk yard for @400.00 working)

Exhaust: RSX Type S OEM exhaust (freevie with tranny lol)

Total: little under $5k with installation and just about every other small part.

Sounds like a good set up when done!
I like to read about "big block" 4 cyl. engines.

^^ it will be starting february. I'm paying off some loan i took out for school. about $1.5k left then the building begins. str8 NA too, then retuning for k20 hybrid with supercharger.

well im just curious about it, but this thread is for those who swapped already, and if u did, and if u personaly think u got ur swap for cheap, than i would like to know about it, and i am planning on getting an a3 boosted when i do get it, also, im not all that balling im only 19 have a full time job getting paid $9 an hour, make about the $300 weekly, and only bills i have is my cell phone, and gas, btw, would it be worth it getting the k20a3 on a 4dr, cuz thats what i have? and another thing, i was on a different thread and some guy said that he has seen this swap go as cheap as $750, to $1500, to 2000 tops, thats mainly why i started this thread, to see whats the cheapest i hear on this swap, so that i can look around and get the swap for as cheap as i can get it, and im going to start saving after christman, and plan to have this by feburary? and whats the differences between the k20a3 and a2?????

I doubt any of the senior members will be answering this question.
Think of why.

 
Rep Power: 279

the k20a3 is found in the 02+ civic si and the base model rsx and have a 5 speed tranny.
the k20a2 is found in the rsx type S and comes with the 6 speed tranny.

The k20a2 and the k20a3 share the same 2.0-liters of displacement, bore/stroke, block, head, valves, and intake manifold. However, pretty much the entire internals and external bolt ons couldn't be more different.

The k20a2 has higher compression pistons, more agressive cams, dual valve springs, and a tri-Y header with larger primaries than the k20a3. If that wasn't enough, the K20a2 has a completely different - and more advanced - method of iVTEC than the a3.

On both motors, i-VTEC really consists of two features: VTC (Variable valve Timing Control) and VTEC (Valve Timing and lift Electronically Controlled).

VTC, in both cases, is simply a hydraulically controlled adjustable cam sprocket that varies intake cam timing on the fly depending on engine speed and load. VTC does not affect the exhaust cam.

However, It's the VTEC portion of these systems that differs.

On the K20A2, VTEC is old school. Like a B-series, the cam has 2 profiles on 1 shaft. At about 6000 rpm, the middle rocker stops resting on the lost motion assembly, and picks up to follow the large lobe. Nothing new.

On the other hand, the K20A3 uses a completely different method, but is still called VTEC. At low rpm, the two intake valves operate with different cam lobes. One valve gets the primary lobe (the taller lobe) and the other gets the secondary lobe (shorter). The exhaust valves always get shoved open by a single lobe with no tricks at all. When VTEC kicks in at 2300 rpm, both valves start following the primary lobe. That's it. There's no 5500 rpm kick in the seat.

Other than this use of a shorter valve at low rpm, its much like a SOHC VTEC D16Z6: VTEC only on the intake side. But even then, can you really call <that> VTEC?

All of that is enough for the A2 to boast a 40 horsepower and nearly 20 ft-lbs of torque advantage over the A3.

A2 Has a compression ratio of 11:1:0
A3 Has A compression ratio of 9:8:1

Haha, I always posted that from k20a.org but was like.. nah someone else will

Whatever you THINK it will cost i suggest adding another 25%+ for un-expected expenses

 
Rep Power: 301

k20a3, greddy turbo with FMIC, Kpro, misc parts...I'm guessing with labour it'll cost anywhere from $8500-9500 CDN for me.

 
Rep Power: 256

wow, my hopes are falling further and further down as every post goes on :-(.. and would me having a 4dr make a big loss of a difference, and has any1 on here who has a 4dr done this swap?

Another question(not envolving k20), would it make a big difference or would it even be worth it to make my LX a vtec, basicly puting the ex head on it?

 
Rep Power: 301

k20 into a sedan is no big deal. it's the same engine bay. IMO vtec head isn't worth it. you'll be left wanting more.

 
Rep Power: 287

^^there's some guy on this site with a k20a in his sedan. He did an auto to manual conversion at the same time. He's actually from ontario. I've spoken to him a few times. http://www.defcon-racing.com/images/...dkcomplete.jpg
