The 90Q (07k?)

Postby Afterthought » Fri Jul 17, 2020 11:36 am

I haven’t worked on this in quite a long time . I started looking at a couple things i should keep moving along on .
Added 3 vacuum/pressure ports on the intake manifold , and one to the turbo for the pressure port for wastegate control.

I think After I find a way to bolt down my fuel rail , and secure the throttle cable , then I should be done adding things to the intake manifold .
Image


For the water line to the turbo I’ll come off the Iabed engine mount block, then I was thinking of returning here, this metal pipe in the thermostat housing because it’s basically at the pump suction so I should have good flow . I would need to plug this anyways if I don’t use it .

Image


Before I make these lines one thing I need to figure out is this . The oil cooler fits best like this but I could probably flip it if I wanted . The only reason I can thing to do that is that if I leave it this way , when I change the oil I’ll have whatever volume of oil (0.3qts) that is held in this cooler trapped and not able to drain out .

In some mock up pics you had an oil cooler in front of the intercooler. Why not there or if there’s room behind it?? What if you filled the oil cooler up with ??? to see how much fluid is left in it. It’s not like all the oil completely drains out of the engine when changing the oil. I understand this is your pride and joy but engines don’t have feelings. A lil crud is not gonna kill it. It all goes through a filter.

It actually fits better the way it is in terms of hose routing , so I was leaning towards leaving it like this rather than flipping it upside down .

There is room in front of the cooler I just wanted to avoid preheating the air going into it If possible .

Battery box is done. I ended up using about a 19 foot cable for the positive .

Next up i think I’ll do fuel lines , maybe find a master cylinder and add some tie rods in the front .

Which fittings did you use on the hard line to AN?

Looks great!

Those are AN -6 to 5/16” fittings .
The fuel line measure 0.3145 and 5/16 is actually 0.3125 to so use these you do need to do a little polishing to the tube .

Awesome, thanks! I'm going to end up doing the same thing w/ the 20vt swap. Ordered a pair of 90* ones from racetronix, but I think I like what you did better.

I think * I’ve added the last few things to the intake manifold . The intake air temp sensor bung is on and now I think that the throttle cable that I have should work , just need to make a simple bracket for it .
Oil cooler lines done . Hate working with large size AN hoses .
Still need to figure lines and location for the catch can but I wanted the more important things to find their place first .

I also shortened this line and made a bracket for it so it can’t twist out of place

It doesn't get as cold down there, but I still default to the fundamentals. The best place for your CC is on the passenger firewall, above the turbo/DP. As high up as you can get it while still allowing the hood to close normally.

Ok. That makes sense . If I ever get it this one running I do usually drive my cars in the winter so that’s a good thought . Also I really need as much space on the other side as I can get, it’s already getting crowded over there .

Looking Amazing !!

So looking forward to seeing it done. You've been busy, I see turbo coolant lines an oil cooler lines done.

You're getting closer.

Keep up the great work :beer: :beer: :beer:
