1600 turbo engines

[BossHogg76]

After coming to the end of my 67 project, and now just sorting out a few niggles, I'm turning my attention to my '66.

This car will not be a no expense spared project, so I've shelved the idea of a lumpy 2276, and started to look what spares
I have collected and what I can put together (with the help of friends)

The long block is a 1600cc which has a knock. it was only built a 1000mile before developing it, so will wait and see what lurks inside.

Whilst it's apart I've got a CB performance crank and rods out of my 1915cc engine which have only done a 1000 miles to put in.
Carb I was looking at a one from a Renault 5 turbo, (Solex 32 DIS) though I have a 32/36 progressive carb on the shelf if this could be
used let me know, and mods would be required.

Cam, I've a C35 lying around, I think this isn't suitable for a turbo application, though if it is it would save a bit of cash. If not would a Engle 110 or 120 be ok?

Turbo, now I've not got one of these lying around, so after reading, a T25 was my first thought. Any bigger I guess would be laggy.

Rockers 1:1.25

Any pointers, help etc, gratefully received

If you're going to buy a cam then engle do turbo versions of the 110 / 120 called tcs 10 / 20

I ran a 1600 turbo for a while with the following spec:

Stock AS41 block full flowed
Mahle Stock size pistons, stock con rods 1584cc
JMR worked and built heads, including 3 angle valve job, stainless valves, dual valve springs.
Stock crank, 8 dowelled
lightened flywheel
CB Performance Header and Garrett T25 Turbo @ 6psi turbo was from a saab 9-3 150hp aero.
Dellorto DHLA40 Side draft
TCS20 Turbo Cam
Pertronix Billet Distributor
1.25 rockers
stage one kennedy with kush-lok disc

Fully Dynod and setup 106 wheel horsepower @ 6psi. Upped the boost towards the end and caused all kinds of hell I didn't know about, including twisting the dowels in the crank / blasting the piston rings to bit. Knocking is a killer.

Thanks for that, much appreciated

Any factory turbo on 1.6-1.8 would probably be about right for up to 10lbs. Any more boost on a blow-through is difficult to seal up on the carb so not much point.
If you go draw-through you'll need to get a turbo that can be carbon-sealed for vacuum, which limits you to either old '80s stuff that is nearly dead or new really expensive stuff from Garrett, Air-Research, etc. There's also Aerocharger which looks great.
Another cheap possible turbo option for blow-through is one of these......

If you go draw-through don't over-carb it, I've made 250rwhp on a bike using a simple Mikuni CV 40, a single SU 1.3/4" works well.

with all the left over 1915 parts I would go that route, you have reasonable heads & pistons/cylinders as well so makes sense to use them, along with that 69mm crank
& rods, get the 1600 case bored for the 94mm cylinders if its ok and have some fun with it

Aye i hear what you're saying Richie, however the heads and rockers have been sold already, an eager buyer with cash in hand was hard to turn away, and with the 66 due to be sat for a while i decided to move them on.

Was just looking to see what i could do with the rest. Was going to put the 1600 in with the 32/36 carb and manifold to get it MOT'd and registered, as it's been in the country for years and not registered. Then i was going to fanny about with it from there.

I need to think about the most cost efficient way to have some fun at York, and a little waste gate flutter and wooshes, appealed  

Modnrod, thanks for the input will have a look into that, from what  Ican see the K-03 is a bit smaller than the T25, so i'm guessing would spool earlier with less lag. I think they used the T25 on the later 2 litre Escort cosworths, and the T2 was on the 1.4 litre Renault 5's. So something that size would make sense i think.

Or i take both ideas, throw the budget out the window and do a 1915cc turbo.......never going to happen
