Yes the manifolds have Tial V-Bands on them.

I have decided to go upgrade my aeromotive 340 to a 400 aeromotive. After doing a lot of research between twin scroll or T4 it seems the twin scroll will spool faster but a regular T4 will make more hp and tq.. So many things to consider with pulse rate of our cars since it is a V motor and equal length runners in such.. I also may bump up to a 1.15 AR but again I still have a lot of things to work out..

Sasha already figured all that out^ and I'm pretty sure his kit comes standard with a 1.15 ar could be wrong tho. Just buy his kit, install it in an afternoon, make power.

Yeah baby!!!!!
Turns out my internals are good but will replace the bearings and maybe pistons rings. Had my lower intake ported and polished and few other flow issues addressed. New block is at the machine shop soon to be bored and everything balanced.

COSMO · 03-16-2016, 08:18 PM

New closed deck block and new front bumper.. Having the motor acid dipped before boring process..

Coming back from the dead is right. LOL Well, Cosmo good luck to you on this build. Hopefully everything goes better.

Looks like the head gasket went right at the water jacket. Once that happened the block let go. Any pitting on the head gasket fire ring?

Bringing this thread from the DEAD!!!!

For those who care and those who don't here don't care here goes......
Built motor from Bobby=Vortex, VSR, PRS,RJM, etc etc etc blown at around 2k miles. The cylinder didn't crack but a chunk was taken out.. lol
Yes I put my faith and lots of money in this guy to find out he can't leave the state of FL due to fraud over 50k, paying on several judgments to others to whom he has blown their motors as well, etc etc. Needless to say after speaking with his probation officer I no longer have any dealings with bobby Ralston.
Goods news I'm having bryan brooks build my new closed deck block with the only precision gen2 twin scroll 6466 switching from uprev to ecutek (no more maf issues with high boost). Before my motor blew it dynod at 748whp and 705tq at 25lbs. I've decided to continue this thread in hopes of saving any other unsuspectful people from his full line of bs but not to to be bashed ( in which I'm sure that will happen anyway on this forum).. Stay tuned and I will post up the motor pics.
Peace...

Here is Bobby Ralston's mug shot from when he was convicted of Theft of State Funds for over 50k. If only I had known..

Meth is a hell of a drug.

And what an idiot. Steal from individuals and you can get away with it. Steal from the state and they'll throw you under the jail.

Sucks to have blown two motors but everything I've heard about Bobby's BS over the years, your experience doesn't surprise me.

Hopefully whoever you have building this one will put together the last motor you need.

COSMO · 03-16-2016, 09:28 PM

Man I'm hoping so. Actually you know him as the guy who made his own twin turbo setup (bryan).. BBR Racing located in GA..

Btw how is your car coming along? Built motor coming soon and more boost?
