This. They do interfere with the MBSP, which is useless anyway. Get a '99 windage try and pan and use that, or spend an hour or two drilling your MBSP for clearance.

Will discuss with my builder today as I'm about to drop this off. If this doesn't get me close to 170rwhp on pump gas, I might kill myself.

Dropped stuff at the builder. He will clearance the tray for arp studs. He ordered arp headstuds, main bearing studs and acl race crank and rod bearings. Will line hone too. Decided not to knife edge and lighten the crank, just clean it up and polish it.

If you consider e85 pump gas since you can get it at a normal pump. You got this.

Nearest e85 pump is 50 miles. No go for now.


Machine work should start next week and he's cool with me coming over and looking at what's being done.

Lulz, just realized my brainysack ms2 has no vvt control. Do I deal with it until I can get my hands on a rev ms3x enhanced, jury rig a spare output as an on/off based on rpm/map or buy vvtuner until ms3x time and hope to sell it later on.

This is assuming I can get my hands on a VVT connector in the first place.

MS3 pro or AEM EMS-4

Keep pestering Dimitris until he finishes the Enhanced MS3... ;) Make a little race - who is first, you getting the engine in the car or Dimitris finishing the EnhMS3... :firedevil

Get the current Basic MS3 (which despite its name, is a fully fledged MS3, complete with the knock and RTC modules), and when the Enhanced MS3 will be ready, you can send it back to me for the upgrade, at the cost of the price difference between the 2 units.

Awesome. Lead time and price? Will my downpayment from 2 years let me jump the queue? :giggle:

This finally came in too. So pretty.

This was waiting at the machine shop for me, yay.

That's a great offer. Will your enhanced upgrades fit into the 'old' style MS3Basic case?

Unfortunately not.

Ahh crap, I did not know this. I have a 2002 motor getting work done and have ARP studs. I now cannot use the MBSP then without hours of fitting and drilling? Is it really a useless item? Can you explain that further?

I think they're useless. They might help with NVH or something, but not for big power applications. I broke a factory main bolt at ~350whp using an MBSP but similar applications with ARP studs hold up just fine. You can either cut up the MBSP or you can use a 99-00 oil pan and windage tray in its place.

Something else I thought of, will I run into clearance issues with the valves and the 10.5:1 wisecos? Ie, not being able to use the full VVT range? Obvious answer would be to clay it, bit I'd like to know beforehand if I can expect troubles. Most awesome would be if it could be kept non-interference.

I did (finally) order an MS3 from rev, so the VVT part should be covered :) Someone was also kind enough to hook me up with the oil control valve connector, so I hope that shows up soon too.

Then it's off to start the wiring for the sequential fuel and spark, VVT and whatever else I need.

My case will help you very little, but may indicate the effort it will take to measure.
ST 11:1, block/head decked 0.8mm in total, 305 cams with 10.7mm lift:
4.7mm clearance at TDC with -13 degree advance (that's what the decking gave).
Measuring at many points revealed that I have contact at 24 degrees advance and beyond (10 degree sweep that is nono).
This was measured without the 0.8mm gasket to simulate stretch at about 8krm.

Do you know how much your intake cam lift at 47 degrees?

Share source for .421 lift VVT cams?

IIRC he built one from blanks?
