NA pistons are not 8:1 CR bud they're 10:1, even the lower compression GTE runs 8.5:1 as stock. If I were you I would stay at 10:1 CR with the rebuild to keep drivability then when you come to turbo it run ethanol on a fuel flex, more boost more power.

 

Dang, will have to see whats about. Would be cheaper to run the old pistons i guess but they'd need a thorough checkover first....

Sitting at my computer at work the other day and I receive an email from the guys at HKS Europe. Attached are some special offers and I notice they had the Silent Hi-Power Cat-back system for a Mk4 Supra going pretty cheap.

 

I just couldn't resist, after having the same system on my old MX-5, my mind was made up.

 

Couple of days later,

Granted, the Engine is in need of repairs, but I couldn't let it go...

Been researching ITB's lately and am very interested.

 

I dont know why, but there is something about a high revving 6 Pot ITB engine that makes the hairs on my arm stand on end.... lol

 

Now before we go into it, I know its not cheap, especially for such minimal power gains. I do believe that think driving the wheels off a lower powered car can be more fun if not just as enjoyable as having power on tap from a Turbo...

 

I found a guy in the US that is already on it though, looks brilliant :)

Anywho, I have other bits to sort first as well as some saving to do....

 

For now, back with the Auto...

 

Found these at work a while back,

Transmission Oil Cooler from a Pajero.

 

The OEM Rad is looking a bit worse for wear so may be opting for a Mishimoto Rad in the not too distant future.

 

Will be hooking this up once the Engine is going back in.

 

Will hopefully have it ready to go back in this weekend, fingers crossed...

Making slow progress but we're getting there....

 

Changed all the main bottom end Gaskets, re sealed the upper and lower Sumps, Stripped and cleaned the Oil Pump and gave that a good clean too.

 

Also cleaning up parts and giving things a lick of Paint as we go. Hoping to have her back together for the new year,

Engine and Gearbox are all ready to go.

 

The only task left was to give the Engine bay a good Steam clean, looks a lot better under there now.

 

Took a bit of work to shift all the Crud and Old Oil of the Sub Frame, well worth it though.

Engine day tomorrow....
