1949cc 260 whp KingMotorsports
I figured I would make a thread specifically for this engine. Here was the thread that originated it. https://honda-tech.com/forums/all-motor-naturally-aspirated-44/kingmotorsports-modded-performer-x-thread-2873074/

^^what he said, very impressive!
I'm building a similar sized engine my self. Will be done in a month or two.
1980cc (85*87.2), 13.5:1 CR, jenvey ITBs, pr3 head with type-r valves (ported locally), custom bisi header, but only Pro 2 cams (just went with what we had from last season). Will run on E85 from the local gas station, or a mix of E85 and regular pump gasoline.
Hoping for 240+whp.

This car is just a test chassis. Engine is being shipped over seas. Power steering and AC are not hooked up.
i read that u can keep the AC belt on ( have the system off ) and just take off the power steering belt for minimal gains .. any truth in this ?
94-01 integra and 92-00 civic usually gain 3-4 whp without the PS belt. DA's usually make a few more.
You guys don't waste any time switching motors in and out of the test car. I can tell that the higher compression makes a big difference, nice graph!
Was there a difference, that you could tell, between v1 and v2 of the modified px?

good build, props on the results
we did a very similar build w/ the differences being 83.0mm bore, little less compression for pump gas and different intake and exhaust manifolds w/ 70mm tb. power and tq were nearly identical.
alot of people overlook the little b series engines but they can make great power if you know what your doing

Very impressive and simple set-up!!
I just want to ask what injectors are you using? and if would be a big difference in numbers if you were using 93 US pump gas (about the same with European 100 octane gas) instead of race fuel?
I can see that you using stock fuel rail and FPR.
I have a similar set-up (building in process) with 13.5:1+ C/R, PRO 2, 84.5*87.2 (1956cc), Toda header and 62mm T/B with Skunk2 V1 manifold.....I hope for 230-240 whp
I have from my old 1.8 set-up, AEM fuel rail, RC 320 P&H injectors and everythink else stock (OBD 0 ECU..is a CRX) and my tunner told me that will be fine with my new B19 set-up!!!???

Yes. Class rules say the plate needs to stay 62mm but can be modified before and after. This throttle body is a spoon throttle body, (Thanks Paul). We did put a 68mm throttle body on it and it wasn't worth anything on the dyno but it felt better.
I really don't think there is a difference between the two or enough to make a difference. The runners are the same length. The plenum may be a hair bigger. It is just easier to make so it can be sold at a reasonable price.

Yeah, I am sure the awesome tuning makes a bigger difference than the difference between the two versions of the px. It sure seems like there is a bit of work involved either way.

Just to fulfill my itch to test the victor x myself. Would you show me some charts of a modded Vx vs Unmodded? also pics would be great. I was wondering what type of gains could be had by modifying the Vx (cut open and ported) would i sacrifice alot more bottome in to gain slightly higher hp?
