Thats good.

 

As for Modding, pretty much the same as the MR2 turbo I would have thought. Decatt, Boost controller, FCD, Exhaust etc. Depends how far you want it to go.

Used to have one of these, fantastic cars they are. As for modding, decat/downpipe, exhaust, induction boost controller set to 1.2bar and hey presto 300bhp. A water injection system would also be helpful to keep charge temps down......... Also make sure the fueling is spot on coz the pistons can be abit on the weak side :yes:

 

Yeah you can get raiser blocks from fensport!!

I also have a ST205 GT-four. Quite easy to modify... rasing blocks are a bit expensive for what they are but they do help a lot with the rear downforce balance at speed.

For rasing the boost there is a guy on the GT4OC website called K1ANO who makes and sells relief valves... combined with a boost gague you can set a pressure of 1.1bar and your looking at 280ish bhp.

 

Check out my vbGarage for a few pics.

 

 

 

I'm going on a trackday at elvington soon in mine... are you up for something like that?

thanks for the reply folks, yeah looking at around 280-300 bhp just so she can keep up with the sti from time to time.

 

Will do some searching on the sites

 

Cheers again

 

As for the trackday yeah sounds pretty cool, have to see if she's willing to track it

I used to have a GT4 running 1.2 bar of boost. Great fun to drive, but unfortunately 1994 - 1996 year blocks were weak. Mine went...grrrrrr

Modding wise, I would tend to steer clear of the relief valves and fit a good EBC. I had the apexi AVC-r fitted with aquamist WI.

Check your front suspension carefully, parts ain't cheap!

Fensport are great for advice and they are spot on for parts. The GT4 God is Ian Smith at the Toyauto Centre in Nottingham. Does a great level of work - very thorough and priced very keenly. His details are on http://www.GT4OC.net

If you need any workshop manuals, drop me a line and I'll send you what I've got on CD.
