1987 Toyota Supra GTtwin Turbo from Australia and New Zealand - Comments

Tuned engine and increase in horse power damaged the auto gearbox.

I then replaced it with a six speed short shift gear box with a triple plate kevlar clutch with no problems since.

Also changed head gasket to a TRD type

to allow for the use of full time ave gas use and higher boost from modified turbos. (standard ct12's machined to fit larger compressor and exhaust wheels) 20psi boost,

And a 4inch o/d stainless exhaust to increase flow.

Absolutely wicked car got it running 460hp at last Dyno run. cornering is wicked, pick up very quick.

Took a bit to get it there, but the basis of the set up was already there

thanks to the 1g-GTEU set up from TOYOTA(nice job)

Also I have run a water/alcohol injection system to give better bite on the long races 20km+ to cool combustion temp and stop high boost detonation.

Fitted a range of auto-meter guages and two set's of five point harness in both front seats.

Also fitted a up market fuel pump with independent computer to feed the fuel amount this thirsty raging beast needed to run.

Average running cost $120.00 NZ per week (weekend drive only?)

ALSO OTHER USUAL MODS TO GO FAST!!!

Next mod - NOS!!! and lots of it.

Excellent article. If you could please email me on dciccarello@yahoo.com I would love to discuss the 2.0L Twin Turbo with you as I also have one and definitely want to modify it.

Same goes for me. I've got a 1GGTE in my GZ10 Soarer. I'm in NZ too. rcckidd@hotmail.com.

Hi I have a 1G-GTE and I am very interested in your mods. Especially the turbos. Any info would be great..

Hi, I have just imported a 1988 supra with this engine. Would like to know any info you can help with. It has a slight puff of smoke when left overnight, I am told its probably valve stem seals... hope so. Any thoughts?

Thanks Geof.

Hi there,

I also have this great engine and I have recently bought a HKS single turbo kit for it! I am interested in the TRD style head gasket you got for it. Could you or anyone with this knowledge get back to me at nightfall01@optusnet.com.au.

Yeah me too! glim@usa.com
