A few pics of my current toy. R5gtt 'sleeper' conversion built/setup by myself. Power is estimated at 190hp.

















This is a vid of it in action at Santa pod last year. With the new engine spec im hoping to drop at least a second off this time when i do a test & tune day next month smile

Thanks for the comments smile

Im in the process of sorting a set of gt turbo spare steel wheels out & fitting them with r888's for a more stealthy look.

Here are a few of the build pics.

The donor engine, out of an early r11 turbo i stripped many years ago.



Van as standard 1.9d.





The first build.









T28 turbo.



The first build finished.



Koni yellows/mintex 1144 up front.



With this engine setup - Fmic/t28/exhaust/16lb boost & carb setup with wideband afr gauge i got 161hp at the fly & 14.6 @ 90 on the qtr.

Got used to the power easily so decided to fit a hot cam to compliment the bigger turbo. Seemed a shame pulling it to bits as it has never missed a beat in a few thousand miles but needs must.

Engine out once again.





Degreeing the hot stick.





Give it a lick of paint.



Removed derv mount as it got in the way.







Engine spec at the moment -

Stock compression c1j/bottom end.
Custom spec cam & vernier.
Piper valve springs.
Armtech rev limiter set at 7200.
Valeo 'uprated' clutch.
Alloy Fmic off frontera.
Tiger 2.5" downpipe/side exit exhaust, Bung fitted in downpipe for lambda sensor.
Carb Jetting adjusted by myself with wideband afr gauge, Fuels for 18lb boost @ manifold for now.
R5gtt fuel system & all fuel lines renewed. Retained the derv tank as it is essentially the same.

Chassis Mods -

R5gtt hubs, Driveshafts & front brakes with mintex 1144 pads.
Koni sport shockers with -25mm springs, Torsion bar adjusted to suit. 1.5 deg negative camber up front.

Goes a lot better with the new engine spec, Cant wait to test it out on the qtr mile smile

The gtt carb has 2 stage enrichment circuit for on boost fuelling. Ignition is controlled via the Aei, Basically a primitive ecu for ign with knock control & has a vac capsule that adjusts the ignition when it senses boost. It all works pretty well for 80's technology.

Give it a clean up today so took a couple of pics smile

Took it down york raceway for a few test runs today. As the surface isn't too good i knew i wouldn't break any records but i were more concerned about trap speeds.

Best run was 14.73 @ 100. All other runs were 14/15 sec with consistent 100mph traps. The cam/18lb boost must be doing the job, No idea how much power ive gained but 10mph up on last runs at the pod.

Best run slip here.

You hit the nail on the head Jessop, Cant leave the van alone lol. Ill get the gtt back together one day.

If the weather holds out this week im going to do some more tuning this week, get the full potential out of the current setup. Taking it down to Santa pod for a few runs at the end of the month, Going to dig my mickey thompson drag radials out & see what it will do on a well prepped surface.

Doen a few runs at Santa pod on fri. Done a new best time of 13.4@97 on slicks, 14.3@98 on road tyres. Hot weather weren't helping things as it felt down on power slightly, Grip/surface was awesome though.

Its possibly the fastest Renault extra van in the world now lol. Roll on 12's when i up the boost.
