how do I fit this Holset in my 244?

(1982 244 GLT+I)

I recently got the notion to put a huge Holset in my 244 (model # HY35W), I've got a guy who will give me a great deal one, but he sent me the dimensions and I don't see how I can get 11.5 inches of clearance where my stock turbo is- do I need a header to locate the turbo higher up? or is there a cheaper way I can go about this...

thanks

a better question you havent asked yet is "how am i going to control boost once i get it bolted up?" and it will pretty much just drop right on...

[taking8]

I won't be installing it right now... everythings still coming together- megasquirt, ignition, and I'm thinking an Apexi AVC-R electronic boost control

[stylngle2003]

right, but isnt that holset lacking an internal wastegate?

if so, you'll need to get an external WG

you can take all the AVC-Rs are EVC-Fconv Vspec2 bull**** and waste your money on them bc they will be useless without a wastegate, so figure out if it's internal or external first

[MattP]

HY have internal wastegates. Check out grebnut's homepage. Not an HY but a Holset of similar size. Make sure you get the inlet elbow and clamp. Dodge wants the mint for those pieces.

[taking8]

yeah I've been shopping around for wastegates- Turbonetics, Tial, HY,- anyone have a good experience with one of the brands? how do I determine the spring pressure that I need?

[The Aspirator]

MattP, I'm pretty certain that Grebnut's is an HY, and he's got it hooked up to a pre-90 manifold. It fits.

Get a Tial wastegate, all others suck. 38mm is what you need, with maybe a .5bar or .8 bar spring. Then use an EBC or MBC to control boost.

Put it this way, huge turbos are really fun, but they ARE laggy and you can't reach anywhere near their full potential on a stock motor. You'll end up breaking part after part. But they certainly are fuuuuuun:

holsets are fun. Do a search.

I'm amazed you guys could get those in the 200 engine bay. IMO it was quite a bitch just to pull/replace a regular T3 in a 200.

100x worse with a Holset. Its VERY VERY difficult. Even the header is bad. Thats why I kept saying "design it to fit a 240, it'll fit anything".

It's acutally not that hard to remove/replace it with a flat flange 90+ mani, just install the manifold first, then slide the turbo in from the front and bolt it up. It's snug though, that's for sure. I probably had less than an inch of clearance, really sloppy or broken engine mounts would make it touch.

what will I need to replace to get full potential from this thing? (est. cost?) new rods, forged pistons ?(I've heard there's some debate over the pistons) ported/polished head? I don't expect to be running 30psi, but I don't want to install it and then realize I'd have to spend 6 grand on engine modifications to get it to boost like I want it to. I was thinking it would be able to give me a good 15 psi boost on the stock engine I have, and give me the opportunity to work my way up as I modify things. correct me if I'm wrong. I expect it to sit around the garage for a few months while I get things together- I've just got an opportunity for a great deal.- on the other hand- should I spend my money on a more mid-size turbo? I can get this holset barely used for 250.00- help me out

thanks

a holset and 15 psi dont mix , so upgrade the rods with this chap

Who says? I ran 25-30psi from time to time I ran over 15psi for 2 years. All the pistons still come to the top of the deck.

[coldfusion21]

yea, i thik the problem is simply spooling it, not making the motor hold the power (atleast not at first) think fatty cam, big valves, and worked head to make it all come together. the head work is going to be bank. i would figure around a grand, min. (altho someone might have a hook-up for less) and i think a nice Sten head is closer to a few grand.

search for the pictures of Peter Lissen's head that he had sten make. he goes my the name "Yea, Right" on the board, also some might have been posted by Ole, who works at the V-Shop with peter, he goes by "310"

[Hank Scorpio]

Actually I think the keys are:

Atleast a K cam
Megasquirt and spark (loads of initial timing will make a world of difference)
HEADER + EXTERNAL WASTEGATE
Biggest exhaust you can fit

You will also really want to have:
oringed 21/23 or 90+230 block
somewhat to very worked head. Oversize valves would be very nice but I got along just fine with out them.

Setup right with a good motor, its pretty reasonable. If I had ANY exhaust leaks it changed the way my holset spooled. Went from very progressive and hard (almost felt like a LARGE displacement V8) to being hit in the face with a 2x4 (it just lagged an extra 500rpm then came in HARD).

Its in the supporting mods.

[taking8]

somebody help me out with this bit:
call me stupid (or more reasonably, 'inexperienced') but the following is all foreign to me, I've heard about it alot, but I don't really know the extent of how you're actually modifying the engine block (machining it or something correct?)

(sorry I hate to have you cover remedial stuff just so I can understand your posts- if there's an appropriate page/thread drop it to me)

But I gather the reworking bit is expensive.
Basically it boils down to this- i don't have a thousand bucks (or the time for my car to be out of commission) to rework my head, is the holset worth it for me? maybe I should go with a t3/t4 hybrid or other ?



thanks again for your help


Coldfusion- I saw the pics of the head awhile back, I can't find them now- but they were gorgeous- I wish I has that type of cash

(BTW- thanks for helping me out again doug)

[The Aspirator]

O-ringing is a quick machining process to the block that basically makes sure you won't blow headgaskets anymore. Plan on at LEAST $800 to rebuild a head with new larger valves, though it's not really a necessity as Doug pointed out.

I was actually quite content with the spool of my holset, and now that I know how to tune better I could have made that much nicer. It'll be back on soon enough, trust me . But I think this turbo is a little out of your range as far as what sort of supporting mods you've got plans (and money) for. I dunno, a T3/T4 sounds like it'll produce loads of power without needing stuff like a header, external wastegate, etc etc. Say your Holset is $250 (a GREAT price by the way) then another $250 for a Tial, then you'll need some fancy exhaust work to get the 4" turbine outlet down to 3" exhaust which I doubt you have yet. That's at least $600 just spent on a turbo that's slower to respond than a smaller one, and doesn't really come into it's efficiency range that often. So an upgraded garret of sorts might be your best bet here.

But hey, I'm not trying to stop you from tossin on a Holset. I love those turbos, can't wait to get mine back on caues they're fun as hell. Just trying to put things into perspective and rationalize for ya.

thanks john-
thats just what I was looking for.
It looks like I should be looking for something a little milder (at least for my use) - don't get me wrong -I'd love to throw that huge holset on there and have the baddest volvo in AK (not that it would be hard), but I'm afraid I wouldn't get it up to its optimum working levels - so maybe for the next project eh? its a shame though... such a great price. if anyone is interested PM me. the guys got more than one. I guess I should expect to spend quite a bit more on a good Garrett though ? I'll have to do some research... if anyone has any leads/ suggestions models, purchase places, etc. I'd appreciate it. back to the drawing board I suppose

thanks everyone

i dissagree. i am on a stock block small rod motor (just a fresh headgasket a hair overtorqued.) and have been running 14+ psi for the past month or so. highest spike was to 22.5psi according to the profec. and honestly, its not that much lag. i am even running a big 'ol cam and the turbo starts spooling at 3k. have fun. later,

ben

edit* i think the key to not blowing up motors is megasquirt, wideband, and biiiiiig mofo injectors. ive peaked out at like 60% duty cycle with 72lb injectors. (tuned for mass richness under high boost. mid 10's or so to 1.
