due to the fitment problems we have been seeing with the 4bolt turbine housing mating to most of the a/c compatible manifolds, we are now offering a 5bolt turbine housing option. the option will only be an extra $50, making the price of a t3/to4e with a 5bolt housing only $599 shipped and the price of the t3/to4e with a 4bolt housing still $549.

we have actually brought in a couple of the popular manifolds to check fitment and try to figure a way to solve the problem without changing the turbine housings. due to the larger than estimated difference in offset, we were unable to divise a solution or than offering the 5bolt turbine housing as an option for those needing it.
i hope this will help to save everyone from having to shave their blocks.
thanks

That is wonderful. That changes my perspective on things a bit!!

Very cool, Is it correct to say that the 4 bolt housing will flow better than the 5 bolt?

 

Ken can you post a pic of the two side by side. I am having a hard time visualizing the difference in them.

 

I 2nd this..

 

looking at the two it would appear that's the case, but i doubt it's enough difference to make a big difference in power on most cars here..

 

problem solved

 

in my opinion, the 4bolt appears to be more efficient. i think the only noticable difference would be spool time..
i will post some pics of the 4bolt housing and 5bolt housing side by side tonite, and point out the offset problem.

we are also working on a new all garrett gt30/35 flowing 65lbs/min. we finished one today and overnited it to FL for an S2000... updates and pics soon

 

why would the older style housing cost more? it seems it would be cheaper/more readily available?

 

I'm guessing it is for the trouble of changing it all over.

 

Ken, I think that is a great idea.
Its probably cheaper for the housing to be changed rather than manifold companys to change their design for both turbos. To much casting process involved.

 

it definitly is. casting is a very expensive and timing consuming process.

 

if ive already removed my a/c, would simply adding a spacer between the block and the mani. let me use the 4-bolt?
