For the money it takes to build a N/A d17 you could have a stock k20 swap that would be 1000000000x more reliable. and put out way more Tq. and rev wayyyyy higher

I just got my civic, and I was also thinking about modding it... but I just scrapped the idea of modding that engine, and saving for something big after the warranty is over (K20a3, yummy). I would suggest doing work to the suspension, I'm having alot of fun with twisties after I lowered my car, while still using the stock engine. Just my opinion though!

Most swap shops, unless you are doing the word yourself you can get a K20A2 for about 500 dollars more than the K20A3. The K20A2 will put out 200 HP compared to the A3's 160 HP. That is how it is here, don't know about where you live.

^^^ It also depends what he wants cause he could get the k20a3 and boost it or k20a2 all motor or even boost that but would be harder i believe because of its high compression

i'd like to swap an A3 in just cause i don't wanna have to use premium gas but for the money its still more worth it to get the A2 with real vtec.

heh wtf? ... only $500 more dollars than a K20A3?

that's either a REALLY REALLY cheap K20A2 or a REALLY REALLY expensive K20A3 ...

A3 engine swaps go for about $1500-2000 ... A2 swaps go for about $3500

theres a lot that goes into building a motor. I am currently building my D17A1 motor. Should be assembled here within the next week. Then in the car within the month.

First off, you have to buy the parts.

pistons
rods
piston rings
wristpins (usually come with the pistons)
sleeves
cam
valve springs
valve spring retainers
main journal bearings
thrust washers
rod bearings
oil pump
water pump
timing belt
rear main seal
oil pan gasket
water pump gasket
oil pump gasket
cam seals
valve cover gasket
head gasket
intake manifold gasket
exhaust manifold gasket
head studs


Then you have to pay for the labor for.....

removal of the motor
disassembly of the motor
flywheel balancing
crank balancing
cylinder hoaning
block decking
knotching cylinder walls to clear rods
milling pistons to fit rods
micropolishing the crank
clearancing bearings
assembly of the short block
disassembly of the cylinder head
Porting the cylinder head
valve job
lapping the valves
assembly of the cylinder head
assembly of the long block
installation of the motor



after all of this, i can guarantee you that with a good tune my motor will be just as reliable as a K20 swap. Its just mine will be made for boost and putting out more way power and torque than any stock K20
