I was thinking in running it with anti lag anyway as I have Simtek on the car and once it gets remapped I'll get anti lag put on but need to see if this turbo is any good for me

jonesy81

mates got one on his classic ra mate ran 12.4s at santa pod at the weekend with no anyi lag either said its slightly laggy but he says turbo is great other wise

To make even a guess about laggy or not one would need more info.
-Exactly what GT30??
A 3036, a 3071 or a 3076,
-What size rear housing/AR (0.63/0.85/1.1)
-Engine spec

Stainless headers that's a roughy spec

supposidly a cracking turbo even in the standard position, nearly bought one myseklf recently, until i found out how much of the block, bellhousing needs cut away to make it fit properly, so changed mind

Didn't realise I would have to start cutting and chopping I though it
Would just be a straight fit

You can unbolt the exhaust housing and rotate slightly but a minor trimming of the bell housing would be required on a MD321. It's only a minor trimming and nothing to worry about.

I love my MD321T (Billet). Not sure what it would do on NON ACVS heads so cannot comment. Someone will be along shortly to update.

I assume the trimming is only needed with a 6 speed? As i put o e of these on a scooby with a 5 speed PPG box and it went on with no trimming of the box.
Then the guy decided he wanted to
Rotate that turbo, weld the penny valve shut and fit an external wastegate lol

Believe that would be correct on 6speed box only yes. My mistake.

So apart from the cutting of the bell housein
Is this turbo idea for what i need

A gt3076 on a .63 should get you 450 bhp !

SC range or MD rage is based on the GT30 core and they should be OK like on the AVCS or non AVCS cars

Ideal turbo will be as above MDX321T or SC42,which should be good like as I said on the AVCS or non AVCS cars
