Just for the "what the ..... is Bill talking about" crowd......
three levels to add to Chike's - MSD Stacker - Ported/Polished/Thermally coated intake and injector stacks - Blueprinted injectors and fuel rails and yes, those are phenolic spacers installed between the injector stacks and the heads and intake manifold and the Impreza FPR -Bill p.s. note that Chike's and my numbering systems are not identical

If I can make two passes I will, but if they see atf on the track after my first run, I'll get booted off. I'm risking being kicked off the track that evening, but hopefully it'll be worth it. As I have an ailing front diff (I'll launch easy off the line) and no stage 2v5 or MAF bypass, if I run a 14.9-15 flat, I'll be pleased. -Chike

Plenty of time to do the MAF bypass! Get busy! -Bill

Nice write up Chike... To anyone interested in comming to the drag meet... you can expect to see that same Stage 3 in my 5mt... I will have mostly all of the mods listed here minus the Phenolic spacers...

I'd probably add those in the Stage 3 category. The MSD ignition is a definite plus, and those others upgrades will ensure that the intake and fuel systems are flowing to the highest level possible. Nice! -Chike P.S. What I see as a stage 4 would either be increased compression or a slight bore on the heads to increase the displacement of the engine. I know I won't be going to this level with my SVX. Once I get the trans replaced, the addition of the stage 2v5 should make this a mid 14 second car which will make me content.

-Bill oh, yeah....here's what "ported and polished" injector stacks look like

-Chike P.S. Btw, I would have mentioned your ebony 5mt being stage 3 as well Tom, but I wanted you to be the one to mention it!

If it gets cold enough on the 25th we'll probably all have to launch "easy" as the VHT they use on the track at the start doesn't work below ~40 degrees (if memory serves me right). Question for you -- a 5.0 0-60 time should support what 1/4 mile E.T./trap speed?

Okay, I'm bushed...
...and I'm off to bed. I'll work on the camshaft write-up this weekend for sure and post it. It'll be nice to see some n/a EG33's make some serious power! Hope others will follow.
-Chike P.S. I was going to thank these people in my write-up but I'll also do it here. Big thanks to Oab_au, Svxfiles, TomsSVX and SubaFreak for all of their help in making these intake cams a possibility.

Cool, Chike. Looking forward to seeing your cam write-up!
Will be interesting to see how it performs on the race... Chike, is it possible ever for an upgrade n/a eg33 beat the one with turbos or supercharged?

If you go to the scoobymile.com you'll see a 15.30 sec SVX that used a turbo system owned by Kevin Donofrio. Needless to say, several n/a SVXs have gone faster... -Chike

Stage 3:
The idea for upgrading the intake camshafts has been tossed around on this site for years. The specs I used were the brainchild of oab_au who based his theory off of the stock specs Wawazat measured a few years ago. Oab_au had helped his son modify his Z motor (which used similar internals to the EG33). The stock specs are as follows: Intake Cams: 7.0mm lift, 236 degrees duration Exhaust Cams: 8.0mm lift, 244 degrees duration I picked up a set of stock intake cams from TomsSVX around the end of summer and began exchanging PM's with Harvey... Stock Cams The ideal intake cam specs Harvey recommended for a 4EAT SVX are as follows: 8.0mm of lift, 240 degrees of duration From here, I began speaking with several different camshaft grinders including Webcamshafts and Ram Performance. However, all roads led to www.deltacam.com in Tacoma, WA. Their sales guy Scott was very helpful and going back-n-forth with him and Harvey we settled on the following specs for the weld-n-grind on the intake cams (their machine wasn't set-up to do 240 degrees of duration): 8.0mm of lift, 247 degrees duration w/ the entire profile retarded by 7 degrees The cost was $150.00 per cam excl/ shipping: Modified Cams SubaFreak and TomsSVX were very gracious to lend their assistance in the installation of these modifed cams, and on Saturday, November 5th I drove up to NJ to do the install. We decided to pull my engine, even though it wasn't necessary, as it would give us extra working room on this install: The valve covers were pulled, and while I replaced the seals, TomsSVX and SubaFreak installed the performance intake cams: The Ride & Drive As lift was increased by 1.0mm, there's more power throughout the rev band w/o a noticeable reduction in low-end power despite the slight increase in duration. My stall speed is still 2,500rpms and launches are still quick but w/o the excessive wheelspin and axle hop I experienced before (i.e. only slightly less torque down low). As the rpms rise, the power comes on with a rush between 3,500-4,000rpms and from there it's a really quick blast to redline! I can't say how much extra power these cams make as the stock MAF is maxed out between 240-250hp (per Mychailo's extensive testing with his wide-band and MAF voltage reader). I would make a conservative estimate of between 10-15hp, but to fully realize the performance potential of this upgrade the ECUTune Stage 2v5 w/ the Z32 MAF is a necessity! -Chike
