20b is Tuned

[rextreme]

My Friends 20b Rx7 is back in action.
Now its run in.

He has given me some specs.

320rwkw at 11psi!

Hp ?? I dont remember how to convert. But Plenty

garret to4e, 1000cc injectors (sec), HKS GT2 wastegate, microtech MTX 12 controller,  bosch 600hp fuel pump (probably need bigger), custom radiator… all the other usual stuff.

Cant wait to go back to Oz and go for a drive.

 
:cool

430atw at 11 psi is \'ok\' isnt it!! Nice

Hope to get mine running this year. Whats the spec on the t04e? very popular in oz mod\'d with a 66mm comp wheel I think? whats the turbine a/r? big I presume, 1.32 or? Will your guy fit a bigger turbo in due course? I think even a tricked out t04e isnt gonna make much more power on a 20B - what dyou reckon? Must be a wicked drive...

Get us some more details on the spec mate Who built the rad? Who built the car up this time? who tuned it? blah blah blah!!

[rextreme]

Yeah power is OK, I guess :rolleyes:
He said it gets to 120mph pretty quickly.:p

More Specs.

Ill ask him for more details.
But I dont think he really cares about turbo sizing.
Just BIG is good enough for him.
He just pays the money and wants a fast car.

I\'ll find out about parts and the tuner for you though.

I imagine that little baby spools pretty quick

Cheers Russ,

Nice to see a 20B in an FD running. I think that the turbo is a little small for a 3 rotor, but it depends what he\'s going to be using it for.

As for the Bosch 600BHP pump, you dont need bigger, you just need 2 of them.

Indeed, must be a great laugh with that t04. If its a /66 with a big exhaust housing it should make 500 I\'d have though.

And yes - Danny twin 044\'s will do the job

[rextreme]

Inconel 1.4 AR exhaust housing, P trim exhaust wheel.
TO4E 72mm comp wheel, .7 comp housing, 360 degree thrust  

3.5” inch dump, into 3” Straight as possible exhaust. Removable cat.

Rochesters 1000cc injectors, malpasi fuel pres reg

Bosch 040 in tank pump.

Jake from Jakes Performance has done all the turbo/computer/dyno/exhaust work (he is supposed to be one the turbo gurus in oz â€" In his shop, there are 1000hp 308’s etc).

Chris Halford (Car Doctor) did the engine fit, and cooling system..
He\'s known for porsche service, race car prep etc...

Cheers for that Russ.

Interesting, wonder what the expectations are from that turbo on a 20B...I know they like their big t04e\'s out there..

[rextreme]

Well I think with boost and fuel he was expecting around 400RWKW.

So i think the turbo was sized for that.
So at the moment I think the fuel problem is what hes looking at.

Traction is a problem at 80mph though.

Ist and second gear is a tentative affair i\'ve been informed.

[20B_boy]

\'Tentative\' - yeah I can imagine!!!

Must be a great drive, lots of torque and quick boosting - Animal!

Lives in Aus hey? I\'m from Perth... where is he?

[rextreme]

Canberra.
But theres a few 20b conversions around now in Sydney.
