gotta ask as to why??? the motor is so small u will need 2 very small turbos unless u plan on having one feed the other and that is hard and expensive to set up

Depends what sort of route you are planning on taking. Ie the Skyline GTR route, or the far superior Supra route. But i imagine spooling 2 turbos of any size at the same time would be a struggle for a 1.3. Someone i know tried the other way on a R5 GTT, having one feed the other, in the end he gave up and put a T3 back on it. I would think the only way that could work would be the sequential setup us used on the Supra, but this is highly complex and almost impossible to copy.

this is pointless, its a 1.3 engine, sure vw did it with a 1.4 but the amount of work involved for no more power, just a bit less lag is over the top methinks.

if you want to go down the big turbo with no lag route its variable vane turbo time. bout time someone tried it.

Twin Turbo is not worth it as you have 2 issue.
1. The motor displacement is too small, with 2 cylinder pushing a turbo mean you are only using about 650cc for each turbo.

2. The "pulse width" of 2 cylinder isn't ideal... you really need a minimum of 3 cylinder to drive a turbo.

vnt turbos have been done a fair few times on 5gt turbos (its like a tdo4 that spins up like a ct9) the only probs some people have had is controlling boost,this may have been solved now though???

i looked into this, i weas gonna have one turbo feeds the other but it came down to be very expensive and i think the boost would be very hard to controll so gave it a miss and buil a 300bhp one instead easier and more fun :rockon:

vnt's seem to suck top end tho IMO. i like the punch of a big turbo :)

i think twin sequential turbos could work nicely but it would be a lot of work as said!

In theory anythings possible if you have the money! I've seen a low cc car with 2 turbo's one very small one that spools quickly and when peak boost is reached it opens a valve which inturn spools the next bigger turbo!
