Testing The Waters

[nelsmar]

No interested in low compression pistons... but I am extremely interested in head studs & case studs... If you have any information on this I would love to know! I am ready to buy right now. Dynasty sells a set for nearly $1,000 and that just seems quite over priced.

It's a combination of both. Good internals but why do you think factory CR is 8.0:1? There's a reason they didn't go with anything higher. The reason IS lower compression allowing higher boost.

I have 9.0:1 in my car at 30psi making 500whp on a twin clutch transmission.

On low, very low boost higher compression is okay but you cannot exceed 8-10psi without getting into the danger zone (enter Top Gun song)

I can't stress enough high boost = low compression, do you think I'm inventing this? Why do you think the STi, Evo, SRT, Most high hp muscle cars all run sub 9 CR's?

There is so much untapped power in the FA20 by lower compression and adding boost.

ARP head studs usually go for $250-$300 so they will most likely be in that range unless there's something special about them, I highly doubt it though

Please don't spend $1000 on head studs lol

IMO if going to the trouble of lowering compression, just dump a stock EJ in there.

You're tearing apart a well built motor, to build it for a different purpose. Easier to just buy one built for the different purpose.

Building an engine isn't that costly. Buying a whole new one an fitting it is very costly. Swapping pistons and rods is way less than a swap guaranteed

if you're going to make uprated rods, pistons, sleeves and head studs targeted at the FI crowd why not do a stroker kit at the same time to make it even more compelling?

More torque!

Stroker is impossible on this platform. Not enough clearance/room unfortunately. The displacement is negligible and not worth it, we already tried.

But...Darton Sleeves bored out to 90mm is a nice displacement increase

You posted testing waters... i posted i have money and am looking to purchase immediately. Are you looking to have them made from ARP? Because as of current I purchased 1 OEM head stud, one OEM case bolt, and I was going to have a set made. But if you already have this process rolling you can call me and ill give you my card info.

edit: I had no plans to spend $1,000 for a set of studs & bolts. I don't know why they are charging so much =/. ARP told me they were working on a kit and they should be out soon, then i called yesterday and they acted like they had no idea what i was talking about. Hell the guy on the phone didn't know what a BRZ was... I figure ill email them tonight for further info, and if not I will have the oem bolt & stud on thursday with a new shortblock.

Do it, sell as a kit, win.

I have everything for sale in the vendor thread

I also have ARP working on them in conjunction with BC. I'm waiting to hear back. As soon as they're ready, first set is yours!

I just PM'd you for further info.

Tell that to TODA RACING. Who already have a stroker kit being tested and will be going to market later this year.

Both in low and high comp versions.

There's no stroker kit that's worth making. You can make more displacement with overbore. We already outweighed the value. It will barely make a difference and the cost for the crank is going to be not worth it IMO.

I even confirmed with BC, there's no worthwhile stroker possible. A boxer engine layout doesn't leave enough clearance with the rod shape to allow more stroke.
