Best performance mod for 23hp vanguard

[SgtRick1775]

Looking to modify the vanguard 23 in my max 2. Seeing many options like rev kits, mikuni carbs and heads on this mud buggy site: http://www.mudbuddy.com/Performance%20Engine%20Parts.htm

Curious as to what you guys recommend for the best bang for my buck.

Thanks in advance.

I put a performance cam and a Rev Kit in a 18hp Vanguard, and removed the governor,,, phenomenal performance! Be carful not to over rev,,, a rev limiter from 600 racing will tame your heavy foot, or gripping hand in our case!!

Also a lil head work, like cleaning up the welds in the intake side, and slightly enlarging the exhaust ports as well and finish it off by polishing, but just the exhaust side. The head work is the cheapest if you do it yourself. There is a lot of power and or torque to be had with our engines with small modifications.

Last but not least,,, do a search here on the site for info, like this one started by site member Jpswift, : http://www.6x6world.com/forums/engin...ification.html .

Heads, timing, cam and carb are the easiest. billet rods will keep it together if there's control issues

HI,
1/ 4000 rpm limit Timing key way , valve spring ,valve spring shims ,HD valve retainers , HD steel rockers and a heavy duty starter motor if not already fitted .

2/ Rev limit 5600rpm
include all of above
remove governor ,new cam 600 racing ,steel pushrods ,rev limit unit ,pistons and conrods optional ,[change carb jets ],change exhaust valve to a single piece unit

3/ above 5600 rpm all components to be upgraded both inlet and exhaust valves changed with 3way valve cut

4/carby option single Mukuni vm33 [has an accelerator pump ]

5/apart from cleaning up castings ,trim valve guide ,match ports ,aftermarket valves with a 3 way valve grind ,the only way a port can be modified is with results measured on a dyno . Most likely u will loose throttle response ,have poor fuel consumption and have the torque/ hp where u do not want it in the rpm band .

The mikuni TM33 flatside has the accelerator pump, 36mm for a 23hp up to 6K. 40 after that

How much $$ we talking for that?

[Nubs]

I would go with the 36mm, its a chunk of cash but it will follow you though your up grades. otherwise i think i have a 32mm with pump N spigot for 150.00, has about two hrs run time on it. i can post a picture of it in the morning if that helps ya.

36mm
carb 300.00
adapter to intake 100.00
spigot mount 20.00

Replace it with a Kohler engine. I will never own another B&S 23hp, have had two and they were more trouble than they were worth.

I can honestly say,, I do agree!!! I’ve had 4 Briggs (one 16, one 18, two built B&S motors, and just 1 Kohler). The Kohler has been put through it’s paces and I’ve had no problem with it at all going on 9 years now!! Ive still got the same compression PSI as it did when it was rescued!!
