My other 1303 GL

[DORIGTT]

Steve,

What width wheels are you using for street, and track use?

Also, are you using this car as a track vehicle only? I ask because of the potential 'soft' skull - DOM steel tubing interactions may leave one...brain dead from what I'm told.

[Steve C]

Hi

The wheels I used to run on both track and street are in my post with Invos fitted. They are 18x8 and 18x10 from a Boxster. I've fitted my front 225x18 R888R to genuine 18x7.5 hollow spoke twists and I went down to a 235x18 Toyo R888R fitted to genuine 18x8 hollow spoke twists for track work.

I've fitted the 245x18 R888R that I used to run on the rear to some crappy Porsche wheels that I have , the plan is to use these at roll racing or the drags. I also have a pair of 18x245 ET streets that are also on some crappy wheels that I can use for roll racing or drags.

I'm a bit of a wheel collector, I also have a set of Simmons OM in 18x8 and 18x9.

And if I feel I need more acceleration I also have a set of 15x6 Cookie cutters with front street tyres and 205 ET streets.

The cage with be padded with FIA approved padding soon

Cool pics Steve, thanks!
I still like your mod to move the whole engine & trans combo 100mm forward. Huge undertaking, but it all makes a difference I'am sure.

[Steve C]

Thanks Wally, lots of welding and cutting.

Looks like I have to use a 1/4 inch steel flywheel scatter shield. I tried searching and of course your build thread came up. I started looking through the 104 pages on your build and gave up.

Do you have any information and photos about your flywheel scatter shield?

These I still had on my phone:




Basically my buddy bend some 6mm thick and 10cm wide plate round the G50, which I welded to my old tranny cradle. Its heavy, but as you said, mandatory to run at most drag race tracks under 11.9 sec iirc.
For circuit use I can unbold the top section, which then saves some weight.

[Steve C]

Thanks Wally, really useful photos and information.

I'm using a Subarugears mount and factory Subaru engine mounts. I could weld the lower part to to the Subargears mount

Steve--

Bit off topic, but what block is that? Any issues with the open deck and being boosted?

[Steve C]

Its a spare block that I borrowed from a local Subaru shop to mock up my chassis, not sure what type. My my EJ207 block is semi closed now

[H2OSB]

That's what I suspected(mock up only). Though I believe the WRXs here in the states originally came with boosted, open deck EJ22s, like your mock up block. My LegacyGT had an EJ255 which, like the EJ257s in the U.S. spec STIs are semi-closed deck. I don't know much about the JDM spec engines you guys get in Oz. I was only asking because I ASSumed with the power you make in your 1303 you would start with a semi-closed deck, though I don't even know if it's necessary.

Have you ever seen one of the closed deck blocks from the original 2.0L(or was it 2.2L) Subaru turbo engines? Supposedly They can take some serious boost.

Hi

Started on the scatter shield today, rain and lack of welding gas stopped progress. Thanks to Wally for sending me some photos of his shield, it really helped. I had a local engineering shop roll me up a circle.

My motor is a EJ207, the very reputable engine builder was worried about cooling in my setup so he made the closed deck with dowels not a fully closed deck. His instruction were with tuning to limit boost to 30 psi and AWD rwkW to 400.00, I made 305 rwkW but I've gone to a bigger rear housing on my GTX3076 and I've altered my air cleaner which was choking the motor. If I'm not happy with the results of the next tune I will change turbo.

I have a Toyota JZX110 as my daily and the GTX would work well on that. Its a cool daily, photo added. Factory manual 2.5 litre 1J and I've added 3 inch turbo back exhaust and Greddy front mount

Hi

Been doing some test drives, wrapped in the new clutch, so progressive unlike the organic Kennedy that I was running, off to the tuner soon for more kWs

[Wally]

Hate to admit, but that Toyota IS a cool car indeed. Dont think we had those over here.

As for clutches, both pressure plate (#lbs) and disk material and construction add to the harshness in my experience. Then again, I’am probably used to “race” clutches by now as my very experienced inspector stalled my car 5 times parking it on the lift 😆

[Steve C]

Thanks Wally, I love my Jap car, great cruiser and very comfortable. We never had them in Australia either, they are whats called a grey import from Japan, nice to have air conditioning in summer

My motor was so easy to stall with the old clutch, and it stunk with the slightest slip when parking etc

Hi

Just got the car back from the tuner, I was hoping for more but it looks like I may have reached the limit of the current setup. Its still scary fast.

Now I waiting for the drag strip to open so that I can have the approval on my cage ticked off.

Hi Steve,
Nice runs!
This is 319 KW at 30psi boost at the rear wheels, right?
That would be 480-ish crank hp then?
Not bad, but I agree, but I would have expected a little more as well at that boost level.
What limit do you or dyno guy think is holding it back?
