Turbo choice for streetable built redblock

[Westmees]

I’m in doubt between the following turbo’s: -TD04hl 22t, -Holset he221w with a HL housing, full blown HX35. Any thoughts?

The setup will be a b230fk with fresh pistons and beefy rods, bigger valved and ported 531 and a home made manifold(stock placement)
I am running a electronic boostcontroller whith boost by rpm.
Shooting for >300rwhp

Feedback is highly appreciated!

auto or manual?

For an auto with stock stall speed I'd want something faster spooling... definitely not the hx35… no experience with the other holset or the 22t

For a stick, whatever floats your boat. Hopefully you have a nice flywheel and not the exploding type.

 

[Westmees]

It’s a manual. Just ordered a KLracing lightweight replacement for my current dual mass flywheel.
I’m really leaning towards the he221w, but I’m affraid it’l spool so soon it’ll be impossible to tune.

 

[Swedbrick]

The he221w will be compatible to a 19t, so tuning shouldn't be a problem. It's basically a td04 turbine with a different compressor design that likes to make more pressure ratio.

Thanks! So I guess the spool would be roughly comparable to a 19t as well?

 

[Swedbrick]

Yeah judging by the compressor dimensions you can guesstimate the closest compressor td04 and work from there.

Any of the no-name off brand or brand name 62/62 turbos or around that range should be good. I'm happy with my authentic Mitsubishi td06 20g on my 16v, but I would have gone with something different if I was building it these days.

If the hx35 is a genuine unit, Id ran that.

 

[Westmees]

At what rpm can I expect boost to start with one of the smaller exhaust housings?

[Mogly]

With a 5speed h pattern, the moment you launch honestly. You won’t regret going with the bigger turbo.
Plus it’ll make 300hp easier with less boost pressure over the other units.

It ain't sexy, but real deal not made in china t3/t4 50 trim is still a solid choice. I'll die on the hill that for most folks on here - myself probably included - a 50 trim will do everything you want, be affordable, and super driveable day in day out.

I've heard really good things about the HE221W on redblocks and other lower displacement cars. Another option would be a G25-550. Pulsar makes a garret clone that a lot of guys run with great results.

I'm currently running a he221w on a freshly assembled b230, pistons from a turbo engine and a 531 head. Now I'm not exceed 3000rpm an not getting full power because I need to break in the engine.

The engine is managed by an ecumaster EMU

Driving impressions at the moment:

The turbo has a great spool, reaches 0.5 bar of boost at 2200 rpm. Car has no problem with acceleration on 4th or even 5th shift.

Don't worry about exceeding 3k rpm to break in. Taking it too easy on an engine can actually make it not break in properly.

I’m very curious what it’ll be like when you have it all set up!
My only fear is that it will be way more of a restriction at 5-7k rpm.

Looking forward to an update of yours!

I have all the parts ordered and hopefully will have the block in the machine shop next week.

I know it's a bit more cash, but the GT2871 or GTX2867 is a really nice paired turbo for that setup. With a .63 exhaust side, it's so smooth to spool up, but you'll have way more capacity down the road.

What type of boost controller do you use?

 

[Westmees]

I’m using a controller from LDperformance in the UK. I have no experience in other electronic boost controllers, but this is a complete, easy to use unit.

wasted spark or sequential? what kind of trigger wheel(s) are u using (cam/crank)?

 

[JW240]

At what rpm can I expect boost to start with one of the smaller exhaust housings?

On my 940, HY35w with 10cm2 housing and partly stock NA exhaust positive pressure at 2k rpm. No boost controller yet so WG opens soon after it spools so I don't know the possible boost at that rpm.
