Ok well I'm beginning a new build and I'm starting with the bottom end of my vq35de. Planning in doing .20 over cp pistons, carillo rods, acl bearings, Arp l19 bolts. I have a vortech supercharger that I run at 9 psi now on a stock motor and I put 400 whp now. I'm hoping to just increase boost on my vortech to 15 18 range and hope that will satisfy my need for speed. The shop I use to tune said I should sleeve my block if I want to push more than 600 whp (I know I won't do that with a vortech that's another conversation lol) but I'm wanting to build this to someday build the head turbo it and push 700-800 whp someday and don't want to have to redo the motor then. Do you think I should sleeve it or what is your guys opinion on that? The shop I use gave me a quote of 6500 for a built block using manley turbo tuff rods instead of carillo. I feel that's really expensive. Any thoughts? And anything else you think would be helpful advice please let me know. Thanks guys for the time!

First part directly answers your question.

 

Search around a bit, there are a few 600+ vortech guys out there. I'll be one of them after the retune with my new blower..

What shop are you using?

 

I was using slowmotion motprsports in Columbus Ohio but after 2 recent quotes that were outrageous I think I'll find a new shop.

 

The least expensive built motor is the one that lasts. Go with Dynosty in KY.

 

Dynosty does have a good reputation. Dont sleeve the block for under 1000HP... I bet they will tell you the same.

 

Dynosty probably has the best reputation around.

Considering that and I had more expensive quotes than a shipped price from Dynosty (I'm in California they're in Kentucky) than a race shop a mile away from my house, I wouldn't go any other way. Eddie used to build sprint cup motors. Tons of experience

 

Cut to the chase, sell the supercharger (I have nothing again superchargers - this isnt my point) and get a built block from Dynosty, IPP, Z1 as a crate motor and go directly to turbo. Sleeve the block only if your engine builder thinks it required for your goals (it's my opinion that this isnt necessary).

The reason I say go straight to turbo (if this is your ultimate goal) is because youre gonna waste time and money leap-frogging to a higher boost supercharger then on to a turbo setup. It's also my opinion that you should stick with/around 600whp...it gets awfully expensive and trouble-some past the 600whp.

to get your 600whp you're gonna spend $5-$8k on a built engine, $6k for your turbos/intercooler, $1-$2k for ECU/tuning, $3k misc/supporting mods...at the end of the day youre gonna be $15k-$20k into this - gotta pay if you want to play...
