Re: Pictures Of K20z1 Complete In Engine Bay!!!!!!!

It runs too rich basically my tuner said just to get a base map into the ecu and he would take care of the rest. Thanks for the props it took me a long time paying attention to detail. I polished the rack and the tie rods to waiting for the motor to come back from machine shop. When it gets back from the tuner I will post more pictures. Thanks for the rep guys!!!!!

Re: Pictures Of K20z1 Complete In Engine Bay!!!!!!!

new SI has a k20z3, new RSX-S has the z1

as for differences, here's what I found

K20a is the J-spec ITR/CTR motor.

In australia the ITR uses a k20a2 and in europe the CTR has a k20a2 as well. So there's 2 different kind of Type-R motors...j-spec and non J-spec.

Differences between a z1 and a1 are...

-cams are different on ALL motors. K20a has itr cams (obivously) K20z1 has their own cams that are better then k20a2 cams but not as good as ITR cams and k20a2 cames have Type-S cams (obivously).

The cams in a k20z1 are in between a a1 and a2...but a1 cams are SO mild of a upgrade over a2 cams that z1 cams are even less. They're better cams then the a2 motor but by a extremely SMALL amount, ITR cams > z1. They're different cams...they have different part #'s.

-Bolt ons: K20z1 has a ITR snorkel and catback...that's it. It does NOT have a ITR intake manifold which everyone seems to think they do, nor does it have the header, downpipe and cat. K20a,a2,z1 all have the same throttle body. The k20a3 found in the 02-05 EP3 has a z1/a2 Intake manifold and throttle body. The base RSX which shares the same motor has a dual runner setup like the 3rd gen GS-R and a slightly smaller TB.

-Compression: k20a has .5 more compression due to more material on the k20a pistons vs k20z1 and a2. Rods, crank, bearings, head, block, pan, everything else is the same/identical.
http://www.intrinsicperformance.com/engineering.html

K20a, k20a2 and k24a2 (USDM TSX) cam specs.

Note the main difference between k20a and a2 cams is the duration the k20a has over the a2 cams. Lift is about the same or a lil less for the most part.

Just imagine k20z1 cams inbetween those 2 cams. Or do a search on clubrsx.com for z1 cam specs.
Back on topic, install looks good man
About how much did it all run you, if you don't mind me asking?

Re: Pictures Of K20z1 Complete In Engine Bay!!!!!!!

Well I pluged the two connectors into the jumper and eliminated the E connector part of the jumper harness and went straight into the ecu with that connector and it fired right up.

Re: Pictures Of K20z1 Complete In Engine Bay!!!!!!!

Hey, congrats bud. I tried calling you last night to see if you got the car started. I havent been able to respond to you on the k20a.org forum cuz I've been so busy with work. Glad you got it to work.

I bet the reason it did not start was because you plugged in the E connector to the Jumper harness then to the ECU.

Thats probably what stopped it from working.

Anyways, have fun!
