T3 ? or go smaller
Turbo Mini Forums

Hi there guys

Names Sean, live in South Africa - I bought a few bits of some of guys on here.

BUT now its time to ask some advice.

I'm new to the whole Mini Turbo bit, but have got a self built 1600 16V GM motor in my other car, it's running 0.7 bar (10 PSI I think) with a TD04 giving me 200bhp at the wheels at 6000rpm, so not new to the whole Turbo bit.

Anyhoo, i just bought a complete metro Turbo set up of a guy locally who bought the lot 11 years ago in the UK, but never put it into the car and he is now going 1300 Toyota Starlet turbo so i picked up the whole lot.

Anyway, i'm looking at the T3 Turbo and it is a SHED load bigger than the TD04 i'm running on the 1600 Opel - would i be better off getting a smaller Turbo for the 1293 that would spin up quicker for the Mini ? and make a plan to fit it to the Metro exhaust manifold ?

nothing worse than Turbo lag, which i'm assuming will happen with the T3 (or am i wrong ?)

Thanks

Sean

A more modern, more appropriately sized turbo is definately a good idea for a turbo a-series but plenty of people still get great results with the T3.

It has however been proven that something modern like a GT1752, TD04 etc produce the goods and offer better tractability than the T3.

The main reason a lot of us still use the T3 is down to price, availability and ease of fitment.

If something is worth doing, it's worth doing half of.

the td04 is something i might try, the dodgy inlet flange means down the back of the block between that and the bulkhead might be tough though

Some TD04's have a T2 style flange I have been informed

Isn't the TD04 a bit on the large side?

They are readily available (compared with the gt17) so i had considered one for mine, but I was put off after a few discussions with other members.

To clarify, I'm talking about the TD04 as fitted to the Saab Aero's.

In the 13's at last!.. Just

someone on here has/did/does run A td04 with good results

Sean the GT1549 like Im using is a good choice and available brand spanking new Japan Auto trading in SA, the only problem is that the exhaust flange is triangular and not square.

The TD04 is also a good choice but I do remember that the Saab guys use it as an upgrade to the GT17.

Here is a pic showing the diff between the bigger T3 and the TD04H as fitted to my 1600 16V GM motor.



Also when i bought all the stuff i got a block that had been freshly bored to take these good used old stock pistons - they look OK and are fitted to GTS rods (Innocenti) with a deep dish.

Do you think they will be OK for low boost ?

Turns out the pistons are from our local 1275E circa 1980-1983 and ran a compression of 9.4-1.

I'm thinking of aiming for between 8.5 and 8.8-1 similar to my other car, would i end up with tooooo much lag with the T3 ?

Was considering moving it on and getting a T2.5 or similar, but there doesn't weem to be to much of a market for it locally, as most of the boy racers got t3/t4 hybrids.

Where will the boost come in with the T3 at 8.8-1 ?

Bin the T3.

1/4 Mile 14.3secs 96Mph Terminal 10psi of boost.

Sorry to drag a old thread up but how come you say to bin a T3 mike?

Just because of the lag it has?

I quite like the T3 on the van. It's a bit like:-

slow, slow, slow (few more revs) go, go, go!

I would probably like a modern turbo more though.

If something is worth doing, it's worth doing half of.

is anyone running a td04? other than the Saab item, where is best to pick them up? mitsubishi's?

impreza TD04 13T,
not running

someone is running a td04 but i dont know witch one, and dont think there likely to say

wolfhound are you still around?, could you tell me what car/engine that td04 is off? is it the saab?


edit, as a bonus the impreza td04 is water cooled, i dont think all the td04s are, all the parts look interchangeable (across the entire range) there seems to be 2 different compressor designs though which are not interchangeable

that person running a tdo4 didn't exactly do a very good job of keeping it a secret at avon last year, lol.

Nic then?

Sorry man, i picked it up 2nd hand for like 75 Quid in your monney, turns out it was nealry stuffed then spent another 300 quid getting it repaired as a new one was over 500 quid here.

On the 1600 its already on boost at 1700rpm. so practically no lag.

I've beed offered a T2.5 loacally but its like 600 quid and i would be lucky to get 200 quid for the T3 even though its fully re-conditioned.

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

I like the lag then off we go.

Understand what your saying about more modern turbos and less lag.
