Slowly putting together the HX-40 setup...

[ForceFed86]

Went with the slightly larger .63 T3 garret housing over the .55 BEP stuff. Few pics next to the 18cm holset housing.



Bought the cheapo 321 SS OBX manifold. Nice manifold for the money IMO, thick flanges, nice welds and the placement is similar to the ERL manifolds. I could have run the 18cm housing if I wanted to with no water pipe or block clearance issues.









HX-40 Pro 60mm 6 blade billit turbo with OBX t3 4 bolt 02 housing




Cheapo Ebay radiator/12” fan setup.


Had to fab up a 45* down pipe the old DP setup wouldn’t fit with the offset manifold. (Pay no attention to the fire hazard breaker box in the background) 





Also went with the 600hp rated jacks transmission build. It cost more than the whole damn car. I don’t like to talk about it…



Using Southbends feramic/Kevlar street disc with a new 2600PP.



Used some bendable 4” jointed HVAC tubing for an intake. Then fiberglassed the ends/joints for reinforcement. Came out good, light weight to boot!  Pics to come…

Looking good man. That thing should really lay it down.

Really nice setup you got going there man.  I loved that clutch setup when I was 5 speed btw.  I've had my eye on those turbo manifolds for a while now but I was too chicken to buy one.  Hopefully it works out good for you and I'll probably pick one up too and convert my setup to full T3 as well.  I was thinking about having my stock 12cm HX35 T3 housing machined for the HX40.. we'll see.

Nice work.  I run that same clutch setup and it works great, once I got it really hot at the track and it was slipping but was back to normal once it cooled off.  I hear that is pretty normal with the kevlar disk. 

On another note I am planning on jigging up and producing a twin scroll t3 manifold specifically for Holset combos.  Shooting for less then half the price of comparable units.  I might be looking for some capable test platforms for it in the near future.  The 12cm hx35 housing on the 40 sounds like an interesting combo, may be a bit small to max the compressor but still able to make decent power.

Thanks…

Did you run the two sided feramic/Kevlar clutch or the std Kevlar unit? I haven’t heard of anyone running the two sided disc yet. I’m curious if it will be to “grabby” for street driving.

 I always thought twin scrolls were a waste for the amount of money invested vs performance gained. Not that they don’t work well, but a small shot of nitrous will out spool any twin scroll. Of course, this is from a street/strip drag racing point of view. I’m sure they have their places elsewhere.  That being said, if they were made at a competitive prices, I’d be running one.

 I always thought it was strange there weren’t any affordable t3/t4 twin scrolls out there for DSM’s. There are a few out there for the Hondas. Honda runner placement isn’t very far off the 4g63. Actually some of the accord 4cyls run DSM manifolds with very slight bolt hole modifications. I’d think with some slight fab work you could swap a dsm flange on a t3 honda mani and go.

For a street car, twin scroll is the cats ass IMO.  If you were to make a manifold, it's not that much extra to do.  I would really like to see affordable options for a true twin scroll T3 manifold, not ones that aren't fully divided to the wastegate(if a single wastegate).

The feramic/kevlar disc is still plenty streetable I believe, and the vehicle I drive it in was 1600 lbs :p

I actually just picked up a 8 blade HX-40 with an 18cm housing I was thinking about going twin scroll but it seems that with the the 8 blade there is no point.  very nice setup you have going on there though I am interested to see how it spools with that manifold :-).

[ForceFed86]

Wow that things nutty! Is it an Atom variation, lotus? My MG midget weighs in approx the same, Although your toy looks like much more fun! What flywheel setup are you using on that? I’m having issues with my south bend setup. Streetability not being one of them. Feels like factory.  See new Thread here…

I agree if you have the means to make a manifold yourself and can do it reasonably I’m all for it. I seem to recall you stating it was a PITA and you wouldn’t want to do it again though…? But if I had to choose the biggest bang for my buck I think I’d go with a $300 (or less) nitrous kit. A 30 shot lasts a long time when it’s just used to spool up a turbo.   

[Mr Peepers]

I saw the clutch thread before this and posted up some fragmented ideas 

It's an SL-R, basically an Ariel Atom clone of sorts. 

The car was using a stock resurfaced flywheel with the Southbend xd-ss(?) PP.  It was a Wilwood master cylinder and there was no clutch drag whatsoever and plenty of travel(normal) at the clutch fork.  Harder to press than stock for sure, but about in-line with most 2600's. 

Yes, the manifold was a PITA but well worth it and satisfying in the end.  There are other factors that would make me not want to make another like having the car 30 minutes away in my dad's garage so I could use his welder before/after I work.
In a nutshell, not something I would want to put that much time and effort into if it wasn't my own car.

[red97rum]

Sucks you're having problems with that clutch.  I meant to respond that I was using the standard full kevlar disk from Southbend.

Was there any machining required to run the Garrett housing with the hx40? Also how far off was o2 housing flange from the stock location?

[ForceFed86]

Housing was purchased from timsturbos.com. It has no machine work. Same price as the .70ar BEP housing.($200) The 02 housing is about 30-45* off. I previously ran a 90* bend right off the DP flange, now I run a 45. They have a bolt on V band housings for the garrets. Or just go with the BEP.

 V-band flange would have made it much easier. But I think the .63 will be about perfect. Should have slightly better spool up than the .70 and not be as restrictive at the .55.

[ForceFed86]

After a boost leak check and another clutch adjustment I decided 400miles of riding the clutch was enough break in. Trans still isn't shifting perfect but that's a different topic.

So I did a few 3rd gear pulls. Worked my way up to 25-26psi. Spool-up is pretty bad. Although I left alot on the table with timing as you can see.  Also using a spring and ball type MBC, not a bleeder.

Feels strong up top once it finally kicks in. Much stronger than the 16g at 35+. I think my 1000cc injectors are about maxed though. Looking at some 1400's now. Trying to sell mine first.

 I'm happy with it, sure wish boost came in a little sooner though.

Video gone 

[Mr Peepers]

When is it really coming alive in 3rd?  Once you get the boost up a bit more the top end should compensate for the lag
