Cool Sharif. Thanks for sharing. Looks real good.

 

I don't want to step on somebody else's glory, but there is somebody about to try this in the Mid-A (Northern VA). Maybe they'll chime in, maybe not. But it should be interesting to see it when it's all said and done...

 

Shriaf - my car has the Darton liners in them now, and some quick data logging will definitely show a HUGE improvement in cooling compare to the Darton MID kit. I ran both kits and the Darton Liners for a street/roadrace car is the way to go! The Darton MID kit runs 20+ degrees hotter than the stock block or the Darton liners. Now for all out drag setup where the car is only seeing -10 seconds of full throttle, than maybe the MID or better yet, fully sealed closed deck would be the best option.

 

Why? We have found it is not necessary... with a good head gasket like the HKS or Cometic and a set of L19 head studs we haven't had any problems with leakage.

 

who is Shriaf??

 

Ah, I completely forgot. The only thing left to do, is to beat the **** out of it on a circuit course to confirm.

Great post, Sharif...

Lots of good information in this thread... Looking forward to see how your next engine runs...

 

LOL listen young padawan, i'll be beating the **** out of you if vids start appearing on the forum of you beating the **** out of my car on a circuit

 

Very informative thread! Is there any specific reason why your changing turbo kits as well? From reading on this forum for a while, I see that the JWT kit is best for road racing, but is the greddy kit actually bad for road racing? I never really see anyone using the greddy kit on a road course and was wondering if theres any specific reason...

 

sick, just sick. i cant believe how clean that is. i cant wait to get past all this bolt on stuff and really build this car, im so excited. the next 365 days are going to be really awesome. seeing stuff like this keeps me really interested and excited about working on this platform. with the supras it was always the same thing over and over and over and except for Leh King and GSC nobody really built them for road racing which i like. im going to be VERY interested to see how you do once you get your new set up rockin.

 

Well the reason I would upgrade to our crank is just not the power added due to the larger displacement, but the fact the it is lighter, and mainly, the oil design of this crank is superior to that of the stock crank and actually produces higher oil pressure and better oiling of the engine during extended high RPM usage (road course).

That and it looks cool as well

George, tell Sam to ship me a complimentary kit, and I will install it right away.

 

Sharif,

I will call Sam right now

 

Sharif:
It is always a nice suprise to see mild wear after an engine has gone through anything but mild use! I was pleasantly suprised as well on my last engine that I tore down, didn't have as many miles as yours, but after 12k miles, the bearings just had the superficial coating removed with mild scuffing...

good job

 

Dang you know who it is too.....................and he said dont tell anybody. Btw looks like a mean setup for the track sharif.

 

The Greddy kit was fine when I tracked it. I was just looking to try something a little bit different. I was also thinking that a water cooled/oil cooled GT series BB setup might be a little more reliable than the Greddy setup on the track, but that is speculation on my part.

 

Have you had problems with bad turbos due to heat?

I think it would be the exact opposite due to the fact that coolant is being cycled through two red hot turbos. Usually water cooled turbos come at the cost of slightly higher coolant temps.

 

I went through a couple sets of 60-1's that had upgraded Greddy turbos. That was an expensive lesson. I have had zero "standard" Greddy turbo failures, but a handful when we upgrade to the larger wheels. So we dont upgrade anymore.

It's always a tradeoff, of course....and it will be interesting to find out how much of a tradeoff.

 

just curious... where have you seen that? because ive always been under the opposite impression as well, it may get a little hotter but the difference shouldnt matter much when compared to the benifit of the added cooling to the turbo. i know a lot of japanese tuners who use mitsu-styled or non watercooled turbos often run them at far less boost pressure during track days than what the car is tuned for, but the tuners using water cooled BB style turbos almost always run them at or very close to what they tune them at.
