Latest update......

i have now fitted a new timing belt and fan belt as I had previously mentioned. The fan belt being slightly shorter than standard due to the aircon pump being removed.

here is a pic of the new fan belt routing and a close up of the part number for anyone interested! (Mat :winky: )

I have recieved my oil lines for the turbo too. This involves the two original turbo oil feeds joining into one via a T-piece and then going to the turbo.

I had to drop the engine in for one final test fit to measure up the adjustments I need to make to the wastegate feed pipe on the manifold. As I have shown earlier in the thread, the wastegate outlet fouls on the steering arm so I need to modify it. I also got my rocker covers painted temorarily.

I also had to modify the top rad pipe and the piece of intercooler piping I had got from the breakers yard as they were slightly to big. here is the top rad pipe before trimming.

I decided to use the older style viscious fan instead of the electric fans for the radiator. This is simply because there isn't enough room for the electric fans as they hit off the pulley wheels.

here is a top view of the viscious fan test fitted and it even fits quite snugly

This is another top view with the fan and the rad pipe and intercooler pipe both trimmed to fit. The standard IS radiator is there too but with the electric fans removed

Here are a couple of pics to show the difference in thickness between the standard rad with and without the electric fans

I decided to remove the aircon radiator too as it is no longer being used. This will save weight and also give more air space between the intercooler and radiator for better cooling

This is a pic of the relocated power steering resovior that was mentioned previously

A close up of the rocker cover

Here is the V-band clamp on the turbo. A flange is welded to the turbo and also one welded to the downpipe. the V-band method allows very easy removal of the turbo etc as it is a one bolt job. It also does away with the need for any gaskets as it seals itself.

As usual more pics as they come :D

This is a fascinating read, you must have so much patience compared to some1 like me lol..

[aido]

This is going really well fella, have to admit after looking at the pics I've only just realised that you're going down the single turbo route here as opposed to the factory twins - this is gonna be seriously quick - what are you hoping for with that turbo again fella?

[Monster-Mat]

nice write up man....

got your phone image today aswell mate.

im just gonna drop you a Pm

[Adie]

Looking great man. Really coming along now :D

[gsportcars]

Should be around the 500bhp mark Aido give or take.

The turbo is the only restriction to more power but as it was such a good price and I am on a tight budget I couldn't say no. Next on the shopping list is a bigger turbo after it is all completed.

[Mr Morse]

Awesome conversion Gav.......will you be bringing her over for JAE 2007?

[gsportcars]

Hopefully will be able to bring both new additions to the family (engine and baby;-) ) over but have to wait and see!!!

[Ellz]

look amazing mate love the gold cover the only thing you've got to do is have one of the clear cam covers so you can see them spinnnnnnning :D love it

[LexusIS200Sam]

coming along good mate, cant wait too see her finished :D

[GALLA_4]

How do you get time to do all this!!! lol

Would love to see it sometime.

[gsportcars]

How do you get time to do all this!!! lol

Would love to see it sometime.

If you are going anywhere near Belfast drop me a PM and you can come have a look no probs!! :winky:

Finally remembered to take a pic of the brakes fitted to the car

Although it doesn't show it that well, the 3rd pic shows the nearly non-existent gap between the caliper and the back of the spokes of the wheel. I can just slide a single sheet of paper between them and no more LOL

I recieved my new intercooler and got straight down to fitting it. The position it is in may be slightly adjusted depending on other factors but one thing is for sure....my standard bumper WILL NOT fit over this cooler

The cooler is an extra 25mm thicker than my old one and also a lot longer.

Some may have seen my post about needing a new front bumper, and here is the reason why. This is the bumper set onto the car and fixed with the plastic plugs between the headlights. You can see how much "more" I would need to take off the bumper to get it fitted. It would be easier just cutting away a whole section around the cooler which obviously isn't going to happen

[Adie]

What brakes are they mate?

[gsportcars]

The ones that Mat made up. I bought them from him.

UK spec supra discs with modified LS400 4pot calipers.

I would comment on how they are compared to standard but the furthest my car has been is rolling in and out of my garage LOL

[TheDon]

would it be worth having a 2mm spacer made up to just give you a tiny bit more clearance on the caliper, i dont know how much they will expand (if at all) when serious heat is put into them (and im sure this car will be putting serious heat into them!)

Car is looking awsome, really wish you the best of luck with this project

[TheDon]

actually if you want i am laser cutting a load of 1.5mm aluminium, i will chuck in a couple of 1.5mm spacers for free if you want them?

[gsportcars]

That would be brilliant mate!!

I have been looking for 1mm spacers and the smallest I can find is 3mm.

The problem is that I already had about 2-3mm shaved of the inside of the wheels to slightly increase the offest as they were catching the arches.

1.5mm would prob be perfect.

Let me know if this is ok buddy

;-)

[gsportcars]

With baby Jay now occupying most of my time the progress with the ISupra over the last month has been slow.

Although I ain't complaining as he is a little star :D

I mean just have a look :winky:

I have had to re-locate my Greddy oil catch tank from it's previous position at the rear of the engine bay. It now sits nicely to allow for the induction pipe from the turbo.

I have also had to make up a custom crash bar to fit over the intercooler. Just used some 5mm thick flat bar and I have braced it from behind to stop any flexing. It protrudes about 15-20mm futher out that the intercooler which should give ample room for the bumper.

[peter026]

A lot of work and thought seems to have gone into this project.........Well done :winky:

I mean the car not the bib :D
