Not sure if you were asking if you could use an MHG without surfacing the block.
If you were, then no. Have the shop deck the block with a fresh cutting bit, so you get a very smooth surface.
And have the lower rear timing cover installed on the block when it's done. The cover must be shave as...
Hmm. Sounds vaguely familiar...
Never seen on of those "RA comparator" tools, very cool.
LOL at the belt sander criteria.
PS- Don't go with a lightened crank pulley.
You're splitting hairs about the gasket. Either one will do you just as well.
As for pumps, I'd say go with Walbro. It's reliable, and it's cheap. Nothing wrong with the AEM,
though one person did mention that it didn't quite fit the stock pump hanger.
If you dont want to smooth the turbo block surface so you can go mhg, AND dont want to deal with higher compression/ cam timing issues assiciated with a composite gasket and loss of deck height, you might as well throw away the block. If you build up the na motor, you cant bump the boost up much...
Resurfacing the head for smoothness would take off very little material.
Using composite will increase your compression ratio, and likely throw off your cam timing.
Walbro pump would be fine for those upgrades, and cheapest option. Just be aware that there are many fake walbros on Ebay.
Spec...
I know that my Tial knockoff would make a nice, calm 'pshh' when light boosting,
But if i went to 12+psi, it would vent with an additional high-pitched tone added to it.
Maybe you just need to increase boost to get the original sound back.
#1. WHAT a difference! Glad you go it done.
#2. That finish is not smooth enough for a metal head gasket to seal. You have to either bring it back and tell them you need it much smoother for a MHG, or plan to use a composite head gasket.
#3. If you go with a composite, You might want to...
