The Supras Single Install

And so it begins

Over the last year I have been saving my money and spending wisely in order to get my single turbo install underway. I decided that when my insurance ran out this year I would get cracking and go for it myself. Well... that day arrived on the 10th of August (yesterday) and I didn't mess about. This is the scariest and most exciting thing I have ever done with a car. Prior to owning the Supra the furthest I had taken a car regarding mechanics was a service. It's been a learn as I go project, and it's just went into overdrive. The aim by the end of all this is 700hp.

The Head

 I bought a head from the supra forum that had been freshly cleaned, skimmed and had new valve stem seals. I bought a set of titanium valve springs and retainers to replace the stock items. The main reason for this is that I want to run just over 7k RPM. The aftermarket springs & retainers just give that bit of cushion. Here it is after all the hard graft.




Before I started

Day 1

I started to strip down the turbo side of the engine. First I removed the bumper, lights, air filter, turbo pipes and intercooler pipes. I also removed the wheels, decats and exhaust.




Day 2

I concentrated on removing the turbos. It wasn't actually as hard a job as I thought it was going to be. Some of the fixings had me swearing at them but only because of how difficult it is to get torque on some of them. The hardest part was splitting the EGCV from the turbo assembly. It just didn't want to budge, I persuaded it eventually though.

Day 3

I concentrated on removing the timing belt, pulley wheel, water pump etc. Again I was lucky, everything came off reasonably easily. The only trouble I had was actually with the power steering pulley.....


After Which my hand looked like this....



Colour Coding

Decided to paint the intercooler as it was looking a little grubby. Got the water elbow done too.

Day 4

Made a good start on the intake side of the engine bay. The loom is an absolute PITA to work around. Think I'm just going to pull it right out the way so that I an get in about everything properly.

Intake, Fuel Rail, Lower Runners, Pressure tank, etc all off.

Day 5

Had an hour or 2 to work on the car today so managed to get the cams out. Once I had started I couldn't figure out why the caps had to be loosened over several passes. After 2 passes they were all finger loose. Of course I followed the manual anyway and just as I was getting ready to remove them the caps "BANG" the cam popped up and showed me why they were done a bit at a time and evenly. I absolutely crapped myself but thankfully everything was even so no harm done, I continued using the order in the manual and it came out with ease. I learned my lesson for the 2nd cam so I loosened them all a little bit, in order, then left it for a minute, this time I got a slight POP after a minute or so and then I continued with the order.

Phew, what a fun day

Found another spare hour so the head is off. I also ditched the charcoal canister while I was at it. Surprisingly no dramas at all removing the head. Very straight forward, gasket is off too. Once the head was off it was necessary to cover it so that no crap gets in.

Day 6

Got a fair bit done today. Managed to pull the loom through the firewall, I still have a couple of connections to disconnect in order to get it right off, the gearbox ones I'm really not looking forward to. I removed the front drivers side drop link (all being replaced) & suspension (for paint) and then stripped the rest of the drivers side of the engine bay. I then gave it a thorough clean & degrease then gave it a quick blow-over. Looking great in the flesh, will really come together once I've got the other side cleaned. I made a start by removing the PS reservoir and I took off the PS cooler.

Definitely adding a PS cooler to the list now, it is WAY past it's efficiency range.

Day 7

The easy part is almost over. Stripping the bay has been great fun, I'm now going to take my time so that I can delay trying to put it all back together. I've decided that I'm going to get rid of the fuse box as well. I know I don't have to but while I'm here I might as well. Need to get some heavy duty tape to protect the wire, will see what I can get in work.

Next on the list is a bloody good scrub, a degrease and a paint.

I then got cracking with the engine bay spruce. Finished off the bay and then set to work on the block. I've decided I'm just going to leave the head so I've left the oil pump. Will give everything a good degrease and I'll be good to go.
