Nice power Ryan! And a great example of a Vr4.


Any engine bay pics?

Any quarter mile time?

Talk about wolf in sheep's clothing. Nice and stealthy mate. Love it!

Clean! Nice to see you on here razza...

Good power!!! Surprised that the heavy duty clutch holds up! Mine died at about 160 kW at the wheels.

How did you get the 2x internal fuel pumps with different flow rates to work?

Yeah Ill get some engine bay shots and put them up.

 

I've had one go at the drags, but I didn't go too well. Firstly the throttle body seals had blown causing a massive boost leak (and dyno showed a loss of around 50kw atw), and secondly my driving is shit.

Thanks Baz. Yeah clutch seems to hold up fine. Will see how she goes after next dyno tune!

 

The two fuel pumps was a stuff-up sorry. Have amended the list

Was the Tb seals issue with the s90 tb? I've got the same on the AMG..

No I had the S90 sitting around at home, so put it on instead of replacing the seals in the factory throttle body. Had to machine out the flange on the intake manifold to suit the bigger throttle body too.

 

One thing is that the car doesn't idle as nicely as it used to. Although it is likely because it needs the tune updated do you have an idle issues with the S90? Do you have the FIAV blocked off?

[CLuTZ]

Looking good Razza, welcome back!

I have an S90 t/b sitting here too- what TPS are you guys using?

Stock vr4 tps on mine... Bolts right up!

[evo-gsr]

And what have you both done with the FIAV?

[bazeng]

It all bolts up as per stock...
Mind you I have a fiav block off plate but still utilising the stepper motor.

[evo-gsr]

Gotcha.
Thanks.

[Ian91]

Gotcha.
Thanks.

If your asking because you are thinking of fitting one on your evo, they are also a direct bolt on for them, stock tps and faiv bolt on and work like normal, I went to one because the big universal one which came with my manifold was cheap and shit, had leaking seals and no faiv so car wouldn't idle, swapped back to the s90 and car runs like stock again:)

[evo-gsr]

Thanks Ian.

Beautiful Ryan. Our cars are twins. Lol

I had issues with a leaky S90 too Baz. Idk if mine is a real S90 or a copy but it relies on the grease retaining seals of the ball bearings to seal boost from atmo which isn't a great idea. I installed some thin greased up o-rings to seal against the housing and the inner bearing race and it held up great on a boost leak test. Idk about the longevity of the fix though, its a pretty harsh environment for the o-ring on the throttle shaft, thats why I greased them heavily.

This tb has a brass throttle valve and another S90 I have has an aluminium one. I'm sure one of them must be a replica but idk which one.

 

Keep up the good work mate. Nothing hits like a black VR4. Has yours been resprayed?

Leak is not good!

I'll monitor the AMG.

 

Mine was not an S90.  It was a copy.  But it idled perfectly and fit well....

[MDK87]

Same here, that's the thing with SD. I didn't realise it until I did a boost leak test.

[MDK87]

Ryan you did a good job of fitting a decent sized intercooler in there whilst keeping your foglights. Was the intercooler custom made?
