1988 GTX Restoration - Going To Be Fun!

Yes I am going to install the factory bungs (upper and lower) in this radiator.

i hope that is sufficient to keep your system cool. I cant say much for the b6t. but the BP & up runs hotter than hell it seems

I've tested this same set-up on my 323 GT B6T for 2 years and it runs flawlessly in the middle of summer in Houston traffic with the A\C on full blast. It is actually designed to support around 350+ hp.

I see a custom intercooler in your future.

Just how big are the stock intercoolers there?

Yes I have a new larger intercooler and piping that will be installed hopefully during Thanksgiving weekend (fingers crossed).

I 'll photograph the stock one next to it, for comparison purposes.

Even better would be a water/meth injection and keep the smaller intercooler thus keeping the charge system volume smaller...quicker and smoother throttle response.

[djcommie]

Charge volume isn't a particularly big metric on something with such small tubing and intercooler. I couldn't tell a single bit of difference with spool time, boost threshold or transient response with a Starion intercooler versus the stock unit, which used the stock rubber hoses and a 90deg elbow of the same diameter.

Looking at that new small radiator, maybe a Probe intercooler would fit perfectly next to it. They aren't the best design, but one with full airflow would likely support 180hp on a car with free-flowing intake and exhaust.

I have one of each of those intercoolers and what you say is true...but...I have a friend who has run a B6T with no intercooler and a water/meth injection.. and that is where you feel the difference and I have felt it..in the AZ desert in the summer time and the EGT's are perfect. Quick response and real linear..in a 140 mph Festiva. Around here the stock coolers heat soak quickly in the summer heat.

[slownrusty]

There is no question that meth or water injection would be cool, and maybe something to look into down the road for insurance and managing AFRs.

The stock intercooler is a dated design that is nearing 30 years old, newer more efficient cores and end tank designs (coupled with affordability) makes an intercooler upgrade the next logical thing to do, which I am planning in the next few weeks.

The new intercooler that I am using is significantly better than the MX6 / Probe GT design and is shown below:

nice parts pile!!! anxious to see that in the mix

Today was a good day. New rear brakes (rotors and pads) and new rear bearings installed and back together.

Broken rear pad spreader clip...luckily found a good substitute on eBay:


New rotors compared to the ones that came off the car:


I needed pads desperately:




Next to do is to tackle the rear bushings and the suspect front right wheel bearing.

Did you get a press?
