Tweaking HP out of Wasserboxers.

Ceebers · Post by **Ceebers** » Tue Feb 03, 2004 12:53 pm

I have a MV 2.1 in my 88 Vanagon.

I recently installed a performance? eprom chip in the ecu, and bumped the timing up to 10 btdc, as indicated with the chip I bought for the digifant f.i.

I definitely feel an increase in power from the start, and in the mid rpm range where the power band seemed to lack a bit.

What are some other ways to tweak a bit more power out of the engine? K&N filter, different wires and plugs, etc..?

Thanks a lot.

You could install some solid rockershafts, swivel adjusters from C.B. Performance...

They make a set of 9mm swivel foot adjusters that will go right in your rocker arms...

They also sell a set of 1.25 ratio rocker arms that are the 9mm's These are factory rockers that have the pushrod cup re-located for more ratio.

Set-up your valvetrain geometry with cut-to length pushrods (if needed) and rocker stand shims.

K&N aircleaner would be good...

Up-graded ignition products would be good...

Good Quality oil in the motor / Tranny would be good...

A good quality exhaust system (header) That's about it without tearing into the motor... Maybe I missed something?

Service the C-V Joints / re-pack all the wheel bearings.

6 ply tires reduce the rolling resistance / help with handling / Improve gas milage / last far longer than regular tires on a Bus.

These tires are the ones reccomended for mid-sized Ford trucks ... Explorer? I'm not shure exactly..

Thanks Joe,

I am new to this forum, and to Wasserboxers, being a type 4 bus guy for most of my vw life...

what would I upgrade in the ignition, and are any brands or models better than others, in your opinion?

Thanks!

I can only reccomend the mechanical / internal modifications... The factory ignition is a good system.

My specialty is building motors... I have done quite a few built wasser motors / related components. These are usually carburated....

My specialty is the Type 5 conversion... Converting to air cooled for Dunebuggies, sandrails, earlier street cars, race cars.

I'm not shure if the Mallory ignition system is compatible with your fuel injection.

i don't give out advice on subjects that I have no experience with...

Maybe someone else on here can speak from experience, or you could describe what you want on the fuel injection Forum?

Good Luck with your project. - Joe

we just finished our prototype turbo kit for the 2.1L Vanagon, it works VERY well. You can also put a "chip" in the stock ECU for an 8hp increase on a stock engine, or a 30hp increase on one with some 1.4/5 rockers.

we will have the chips in 2 weeks if you are interested.

The 9mm adjusters ONLY fit the CB 1.25 rockers--- Them fitting the std rockers is a bit of disinfomation I started. (my bad) Stock VW/wasser are 10 mm. A cheap way to go would be T1 1.1:1 rockers, they have 8mm adjusters, and would take the Real Porsche adjusters John sells, probably need the same .060 inch removed for clearance, easy to do. Should practically eliminate guide wear//adjustments, even with solid lifters.

I have hear nothing but good things from bolting on Berg (or Scats copy) 1.4 rockers, assuming a stock cam.

With the chip, it should really sing... 30HP is a LOT from a bolt on combo on a 95HP engine, but appears realaistic, as Boston Bobs #s are about the same, even more with a little porting/big valves.

I'll be harassing John in 2 weeks... If it doesn't hurt too bad.
(Discounted combo on rockers + chip?)

Is the 1.4 berg rocker + porsche adjusters still OK on a 1.9 with an engle 120? I tried to find out a little while ago, but found out that I needed to disassemble and check all the clearances with a dial indicator etc etc....

The Berg/Scat rockers cannot use the Porsche adjusters, mutually exclusive parts.

John, send pics to [email protected]

What do you think a production turbo would go for?

Thanks,

Chris
