300D,
So, how can I help? I can say the 357's are great for high economy, power, not so much. The Firad's we sell, But not the Bosio. Got screwed by Bosio too many times with bad quality control... I just had enough. RC3, we often carry on the shelf in various tunes from Jeff.
Want a reality check? 11mm pumps are overrated. Especially if all you are using are 520's. You'll have to raise the IQ to a taller number to reduce overfueling. Also, every 11mm pump has a fuel cooler. Look under any automatic car with a 11mm; you'll see it under the passenger seat. Hot fuel expands. Sometimes, the additional stroke pressure is lost. Fuel heat at 90c is normal. When it it's 160c, you've lost substantial fuel volume. 2.5" exhaust, we wouldn't argue. We have some deals with those, Garret Turbos from Europe, bushing kits, yup.. But the stiffer suspension? Depends. Are you looking for ride height? Wrong way to do it. Your ride will be bouncy, stiff and uncomfortable. The front, we use a 20 or 40mm spacer under the isolation bushing on top of the McPherson strut. Also, they have a bad habit of crushing down and sometimes, just replacing the rubber bushing gets you subtantial ride height improvement. I've got an XL hand... when I can't fit my hand between the stock tire and the fender, that's a crushed rubber mount. We also do the shocks, normally, but life for OEM's is exceptional. The hype on shocks; same the world over. If you aren't running rally races, save your money.
The clutch, that is a whole thesis in itself. To start, we balance every single flywheel and surface the pressure plate surface, 12 at-a-time and ship directly from us. Average misbalance is 2.4gr. Pressure plate surface is often done incorrectly or off plane. A properly cut flywheel, done on flywheel cutting equipment is a thing of beauty. And the clearance between the ring gear and the pressure plate surface is correct. Some 'cheat' and make it short, to increase holding power, but don't leave enough room for the pressure plate to clear. Stupid mistakes we correct.
We always drop ship the pressure plates and discs. Why double up on shipping? They do a good job from our warehouses. Depending on your expected hp, which doesn't seem to be all that much, if you are going to be below 165hp, we would recommend alternatives to SBC that are not only adequate, but in some ways better... price being one of them. But don't get me wrong. Jon and DJ at SBC know me and we ship from there often. Depends on the need.
We are just a Ma and Pa shop, but we keep extra busy and I think we know what we are doing. Much of what you are buying is not overkill, except the downpipe is not necessary until you hit higher hp. We generally cut a hole in the CAT and knock out the ceramics. That is the single biggest backpressure issue at lesser hp ratings.
Sometimes, these PM's are covering issues that a phone call would do quicker. Feel free to do so.
