Just wondering what turbo's can actually be fitted to the ERST exhaust manifold?

I see things like ".60 A/R Compressor" and ".63 Compressor"

Also I see statements like "Internal Wastegate set at 12 Psi ", are they referring to the actuator? If I wanted to run more boost I would simply replace the actuator ?

Thanks for any help.

any advice ?

its all down to what your spec is and what you can run

get 1 of these built to flow 350bhp and no lag , internal waste gate





or 1 of these built to flow 420bhp and no lag using ext waste gate

Stuart,

1. Not everyone has got a spec suitable for a turbo/manfold like that.

2. NO lag? You sure?

ok minimal lag if u want to be perdantic about it

1st turbo was at full boost 2k earlier than a T34 so why is that not suitable for any engine spec if u want resonable power

T28 RST

What turbo is it

custom built gt25/30, made 2 bar of boost by 2.8k on my engine which runs a really wild cam so it would be even better on different cam

i love your car hows it coming on wernt you having more work done on it a few months back

I suppose I could re-phrase what I said, and put it into a question...

Will any old turbo fit the ERST exhaust manifold, or is it dependant on the A/R Compressor etc... ?

For example, could I fit a GT28 with a .60 A/R compressor to the ERST manifold?

Thanks.

No, the GT28's generally have a T28 style flange which is a different bolt pattern to the T3 flange.

The GT28 0.60A/R Compressor covers are slightly too big also. I had to carry out modifications to get it to fit.

So what options for turbo choice do you have if you want to retain the standard exhaust manifold?

It's back to the question of what you want and what spec you have?.......

Stuart - graphs please

graphs for wat its not about the power it made its the fact that when u drive the car it is some much less laggy and u get full boost so much earlier

Which is why he want's to see power graphs. So he can see how the power comes in.

there u go shows u nothin
it looks like the first 1 has loads of lag when in fact it was so much more responsive drove better and was so much faster

and the second 1 is with a t34 on and was crap boost a 4k

if it was still together i would let u drive it and u would no wat i mean

Stuart, without wanting to sound picky, neither of those graphs show anything that is unexpected. Both are laggy turbo's and both show that on the graph.

My GT28 (which is known in the Jap world as the 'Disco Potato', due to it's fast response) wasn't on boost that early.

My GT30 doesn't make full boost until after 4000rpm, even later with the bigger turbine housing.

The same turbo on a 200SX 2.0 16v engine isn't much different, so why should a turbo like that have 2-bar at 2800rpm on a tiny 1600cc engine??
