Well the modding bug has hit me again. I have always wanted something above the norm. The stars have aligned and it is now feasible for me to do it. My current kit will have a new home on my friends car. It served me well and was top notch.

Car as it sits now:









These arrived this past week!




Setup will be roughly-

Twin precision CEA billet 6262's
front mount stainless twin kit built by Turbo Joe @ Straightline performance
existing forged 370 CID built by my good friend Jason
Lonnies double pumper with -8 feed -6 return and 80 lb injectors
Built t56 etc etc

Looking for 800 wheel on pump gas. I don't think that will be a problem based on other's results. Hoping to be able to turn it up to 1000 hp!

 

Very nice those turbos are awesome keep us posted.

 

Yes...can't wait to see! I think those turbos won't wake up till! Round 800 HP

 

What is the opinion on the 317 heads? Will they become a restriction at this point?

 

Awesome!! Subscribing to this.

 

I personally would want them ported. The better the engine runs N/A the better it will run under boost. Period. Look at my sig and you'll see my hp numbers are at 14 psi. Granted its on E85. But the fact is the more power it makes N/A the less boost it takes to make what you want.

 

Is there real benefit going with say a 220 TFS over the ported 317 besides the thicker deck?

 

Anxious to see how this turns out. I have ported 317's i did myself on my lq4 and I'm running turbos with similar specs as yours. My build isn't complete yet so i want to see how yours goes because we have similar goals. Good luck

 

No. Not to me there isn't. You goals are like mine. I wanted 800-1000 rwhp depending on fuel and boost. I decided I like the safety of e85 so I went that way and with a very low boost level made my goal. Since there are so many guys making 1000 rwhp with 317's I spent the money elsewhere. Ported 317's are half the cost of ported AFR's or the like. I put that money difference towards a capable fuel system.

 

Nice 'Bird there, I will be watching your progress eagerly.

 

hmmm.. I'll have to weigh my options. I already have a BA fuel system so i guess i can justify pouring more money down the toilet on heads .... hopefully working on the car tonight after i get done studying... thats if the roof doesn't blow off my garage.

 

Very nice. I just dyno'd my 370 with twin 6262's, you're gonna love it. Instant boost.

 

oh? details?

The 7675 was fun with insta-spool, i would imagine these spool similarly?

 

Got the old turbo kit off last night, certainly much easier coming off than going on.



Comparison, new turbos vs old turbo (pt76GTS)





I'm going to have to stand up the radiator. Does anyone know the p/n for the radiator that tucks under the front core support? I think that looks the cleanest.

 

subscribed.

interested in how you do ur hot and cold side and ur intercooler.

 

Its the regular griffin eveyone uses. just takes more cutting/trimming to the top and bottom

cant wait to see results

 

What this guy said.^

Just need to cut part of the bottom of the support where it's angled to sit down in there.

 

Most of the materials have arrived and the fabrication has started

here is a sneak peak:



Also began my radiator relocation last night, hopefully i can finish it up tonight. I am doing what Stangkiller did. Radiator tucked under the core support, very clean and functional. Hopefully update later with the finished product!

 

Sweet *** setup man, it's going to be a monster on the street. I'm in the process of what you did with your first set up, so I'm really excited to see yours finished!

 

You will be pleased with it. I really enjoyed my old setup but the fact that it was T4 and designed around a tc78 (the 76gts was a VERY tight squeeze) didn't leave much room for growth. With the 370 im sure i could have made 700+ but after that it would be really pushing it. I will say that spool and throttle response was insane.
