Thread: Thoughts on a full race motor setup

If you talking about 1.3 Swifts.. here is local hillclimb driver at local track

YouTube - Filip Zelensky - Suzuki Swift Kit Car - Vsetin 2/2008 KWBT

Car is about 1400lbs (620kg) and 160hp. Fast as hell. He is faster than EVOs, STis,.. check his other vids too, especially onboards.

<---(Paying close attention.) Great read!

Hmm Suzuki Swift mannnn......Been looking for one for about 1yr

I'd love to see a couple of consolidated threads like this based on n/a build too
eg options for tuning such as

N/A
a) std bolt on motor (best way to optomise the cam timing etc)
b) rebuilt std displ motor (eg what pistons/rods are best for what compression etc)
c) stroke/bore options (eg what pistons/rods are best for what compression etc)

the same for turbo setups would also be awesome

Turbo
a) std motor with bolted on turbo gear
b) rebuilt motor at std displacement (what pistons/rods are best for what compression, and suitable turbo)
c) rebuilt bored/stroked (what pistons/rods are best for what compression, and suitable turbo)

Be a great addition to the FAQ thread i think.

Anyway, apologies for the interruption.
I think the MSS could be handy in the above situation where you want to activate cams at a certain TPS/Pressure with the correct sensors

haha, yea, I know. But look up specs for the b18c5 motor on google. You will find that they have a very low lift and duration for such a high rpm. Only 10.5mm lift on exhaust and 11 or 10.7 on intake iirc.

I will try and find some more specs. I looked at the DSM cams too, and they are also a somewhat low duration.

awesome thread indeed, but hey i did start it hahahaha

neways i got my buddies 2.2L build running finally after some minor issues with the calum ecu keeping the vvl triggered no matter what, still working that out with Calum as to why its happening. But it runs really really smoothly. After the breakin is done i will do another compression test. I did one already after only driving it like 10 miles and it was right around 250psi accross the board which seems about right for 12:1

Now i just have to fix the vvl issue so that by the time breakin is done it will really kick some butt. I still need to set the timing and tps to where they need to be but other than that its all finished up and the car that my buddy hasnt been able to drive in 7 months in finally back.

ITR Cam Specs (DC5)

Int mid: 224 @ .050" / .276" lobe lift / .483" gross lift w/1.75 ratio
Exh mid:219 @ .050" / .241" lobe lift / .422" gross lift w/1.75 ratio
Int sec: 176 @ .050" / .161" lobe lift / .273" gross lift w/1.7 ratio
Exh sec:175 @ .050" / .154" lobe lift / .261" gross lift w/1.7 ratio

Exh pri: 171 @ .050" / .148" lobe lift / .251" gross lift w/1.7 ratio

US RSX-S Cam Specs

Int mid: 217 @ .050" / .276" lobe lift / .483" gross lift w/1.75 ratio
Exh mid:212 @ .050" / .246" lobe lift / .430" gross lift w/1.75 ratio
Int sec: 165 @ .050" / .168" lobe lift / .285" gross lift w/1.7 ratio
Exh sec:170 @ .050" / .167" lobe lift / .284" gross lift w/1.7 ratio
Int pri: 160 @ .050" / .164" lobe lift / .279" gross lift w/1.7 ratio
Exh pri: 165 @ .050" / .167" lobe lift / .275" gross lift w/1.7 ratio

These figures are taken from the lobe...not the valve.

Does anyone know duration of the VE various cams at .050" lift? Maybe then we can get an idea on how the VE cams relate to these specs, just for kicks. I know you can't compare the cam grinds directly against each other but it can give us an idea. The Exhaust side looks to have little duration.

I posted earlier that the B18c5 cams were a low duration, but it seems like that 240 duration was measured at 1mm lift, so they are actually:
Int-278 dur. / 11.5mm lift
Exh-280 dur. / 10.5mm lift @ 0m lift.
But they still only have 25* overlap? With that duration it is hard to believe that overlap #. Perhpas others can clarify?
