1600 TP Turbo Engine Toy

I finally dug out the 1600 TP I have siting around which will become my turbo play toy. Im going to fit this to my Formula Vee for clubdays and the occasional hillclimb. The engine is to remain stock apart from dry sump and ill just transfer most of the running gear from my F-Vee racing 1200 such as fan shrouds ignition and so-on. Im building a barrel 'box for it with some close ratio straight cut gears i came across and a 3.8:1 L-bug diff. The 3rd and 4th gears are quite close and very low. I would imagine they were in something like a sand rail or the like as 3rd is about 1.4 and 4th is 1. 2 something (from memory). Since the engine is stock and will only be revved fairly slowly, prolly around the 4500 to 5000 absolute maximum it will need a tall diff with those short 3rd and 4th gears to make any speed. I reckon it should be lots of fun and make the right noises at the circuit! I have a Garret T2 turbo (Pulsar turbo ET) for it pulling thru an 45mm HIF SU off a Mini Metro turbo. I had a tough 200 mm clutch built for it as well. With a low boost setup I imagine it should see happily around 100 RWHP which should make a day behind the wheel pretty interesting! 480 kilos and a hundred horsepower ATW ought to go quite well and pull like a bull from low down with the little T2 on about 6 Lb boost for tyre frying fun and games. I was doing a trial fitup of the flywheel and so-on and after bolting on the fly, there was a mile of radial play in the crank suggesting rooted bearings..........(I really hate that (sighs)) Closer inspection and frigging about revealed that the crank and bearings are prolly ok but the crancase is severely slogged out front and back....arrrgh! this things been given a flogging in its day. I stripped the engine this arvo and the front and rear bearing housing are completely slogged out and the rear housing is badly cracked. Glad I didnt try to fire this thing up! The bores, pistons, rings and other stuff are still in perfect condition indicating a relatively recent rebuild has been done to the engine. The crank is pristine and standard size journals. So out to the old engine parts pile and hunt thru the rubbish and dragged out an old twin relief case i knew I had there. Altho is been chucked around for many years, a few slightly bent studs and all the pistons are broken, the case appears to be ok with the correct cylinder spigot size so I whacked that onto the engine stand and stripped it. Its a shame really as the crank and rods are in quite good order apart from some surface rust but the middle main bearing has seen water and the journal was too badly rusted to consider so I cant really use that crank and the bearings that belong to it which are in really good order. The case will have to be hot tanked and given a really good blow out after tho as its got that evil smelling old mix of oil and leaves, grass clippings, spiders, wasps and so-on in there! So my cheap and nasty instant 1600 turbo engine is starting to rack up a bit of a bill now. Ill have to find some bearings for the thing, give it a quick hone. The lifter faces are pretty concave and the cam shows quite a bit of wear in the original engine but i should be able to ressurrect the cam out of the junk case as its in better order and the lifters are still pretty flat. Anyway, kinda ruined my afternoon really but you get that. More later once i get the engine screwed back together. l8tr E

Ive been pretty slack over new year. I started a new job as well with a lot more hours so work on the toy has stalled a bit.
Sadly, I cant take any pix this minute as my camera is in Sydney on holidays!

I have fitted the complete 1600 engine into the chassis now and done the clearancing for the 12v flywheel inside the bellhousing.

There was no real way that the T3 manifold stubs could be made to fit my chassis tho. Not easily enough anyway.
It would have required some pretty fancy cutting and shutting of the tubes to create the compound bends I need to kinda mimic the stock aluminium 1600 end castings sos to keep the throttle body in the stock carb position.

In the end, I cut the inlet runner tubes right down to short stubs and extended them straight up by 35mm using some 1 & 3/8" tube which sleeves onto the stock pipe nice and tight.

I used a length of 2" pipe and notched the 2 runners into this to create a small "plenum".
The plenum tucks neatly up under the chassis rails and into this I notched some 1 & 3"8 pipe which the stock inlet log connects to with a length of rubber tube and hose clamps.

Its reasonably cheap and nasty but this wont matter as this setup is not about max flow or horsepower. Im only pushing a 380 kilo car dun forget! Anything will go fast!
The engine will be hard cut at 5000rpm so just about anything withi reason will do.
particularly on a force fed engine.

I had even toyed with using a pair od single port heads and manifold that I have using a single injector each side........nah bugger it!

More later

Yeah M8, it has crossed my mind many times............... however................!

The other consideration is that the T3 injectors are a generic everyday Bosch hosetail injector and its a simple matter of removing the T3 injectors and replacing them with the Pulsar turbo 230cc injectors.

Since the EMS ecu is currently running my Pulsar turbo, its pretty much a matter of hitting the key and go have fun with perhaps some fine tuning for raggedy areas as opposed to a complete re-map of the fuel system to get it going with 2 larger squirters!!!

Take the easy road grasshopper, if you can LOL!

Would look tough tho!!
