Got a question on different turbo options for the FC.
 
Not looking for mental power, so BFO turbos are out really.
 
But looking at 2 possible hybrid turbo solutions.
 
1st Option is a T3/T4 Hybrid with a ported wastegate and high flowing hot side.  The front end is a T04B with 60 trim.  Good for upto 450BHP
 
2nd Option is a HT18S/T4 Hybrid with a ported wastegate, hiflowed turbine (but still twin scroll) and a T04B front end with 57 trim.  Good for upto 400BHP
 
Both the front ends are virtually identical, and the turbo unit would be a direct bolt on with no manifold changes or external wastegate.
 
I will not want to make the maximum out of either option, just looking for mid 300 at the fly, and the fuelling will be setup to support that (larger secondaries and more use of the primary injectors).
 
So the question is does anyone have any experience of the T3/T4 hybrids - what are they like as regards spooling up, as one thing I love about the HT18S is it\'s quick on the boost.
 
Any advice much appreciated.
 
Cheers,
 
Prof.  :cheers

Just look at 88GTR \'s setup,NOW that is how a 2nd Gen should look...even tempted me towards the 2nd Gen !!!!!!!!!!!!!!!:Hammer :guinness  What am I saying ?:rolleyes:

Prof

Yeah - that car does look good Era !
 
Thing is I don\'t want so much power in the car that the engine rips itself out of the vert!  It might have a strong floorpan, but its not as rigid as a coupe.
 
Still, quite a few Yanks are running 300-350 in the soft top and seem to get away with it, so why not one of us limeys. :cool

You can go for a scaled down power version,but the setup is soooooo impressive..:yes :Thumbsup!

Hi Prof,
Your first option won\'t hold 450. To make a pretty strong, not over the top setup i suggest you use a Microtech, TO4E hybrid, 1000cc secondaries and your Arc cooler. The T04E hybrid will use a Turbonetics cold side with S5 hotside. Give me a shout on 01980654188 to have a chat. Price wise, i should be able to get the lot for under a grand.

Injectors, microtec and turbo for less than a grand,  that sounds a bit cheap?

Hi John,
are you settled back in good old blighty?

When are we gonna see your beast in action,  you have a title to retake!
400 BHP - 650 KG\'s = 616 BHP Per Ton of Rotary Power

That\'s the way to do it! :Thumbsup!


88GT-R

Hey Ant, hows it going?
Settling in, bloody weather is crap though! If Prof is interseted, i may be able to pull a few strings to make it as affordable as possible...all depending on the supplier!

You see, something about the title is that it has always been mine... i am just soft enough to let you pretenders walk the walk!!

Love
John

grinder

did someone say microtech :D :D

john - you got a cheap supplier or something ?????

Yes - thanks Stu!  I was looking at some from Canada on eBay - but always get done for postage and duty on those - so the ones you sent are a good price.

Still can\'t find any springs though :(
