When i can drive mine expect 150mph plus terminals(might take awhile though-2010 is looking good),chris has already done a 147,garys engine made in excess of 650rwhp in oz.Come along with james to the fastshow, hopefully weather dependant we might see some 145 terminals(if i cant do it, i am going to strap ross in, with a brick attached to the accelerator):Thumbsup!

@ Ed : What would you suggest is my best option ? I want to stick with the above but maximize the performance of the car... What would be a realistic goal with porting etc ?

 
if you wanna stay strretported with boost of say 1.2-1.3 bar i would say the 4088 will get you about 430-450ish rwhp.....go bridge youll be closer to 500rwhp.

Is the GT40R not the bigger out of the two ?

By the way, thank you all for your patience !

Between the GT4088 and the GT40R as these are listed as two different kits on rx7store.net ?

One is journal bearing, one is ball bearing,the latter is a better turbo,should cost alot more,
Turbochargers > GT40 Family >GT4088 - 703457- 2    
* Journal bearing turbocharger
* Oil-cooled bearing system  
* High Load Capacity GT Journal Bearing System
* High performance BCI-18 compressor and UHP turbine
* 6-bolt turbine outlet flange
* T4 (International-style) turbine inlet flange

Need to make sure the manifold is designed to utalise the twin-scroll of the turbo, otherwise it wont be as efficient as capable of.

Going to save up a few more bucks and get the HKS T51 of rx7store.net

Thanks to everyone for the information and help. Hopefully the car will prove worthy of your time:god

good choice if you want to get to your 600 target, plus the T51R V band exhaust manifold and rear compressor housing is a unique design which has good flow characteristics rather then the traditional T4 type square flange footprint.
Make sure the porting of your engine is big enough to spool that sucker properly

No point in cutting corners for the sake of a grand... I\'d only be kicking myself down the road.

Oh, and if you are even remotely contemplating trying to power map high hp cars on the road you need your head read. Its irresponsible, sooner or later this will be proven very much for the worse I fear. Fine tuning on the road after dyno time is one thing, pulling 1.6bar on the road on and off for a couple of hours while doing a complete map is going to end in a custodial at best if you\'re caught!

Ooookkkkk then....
