Turbo conversion cost?

[Gunni]

What have people been spending on their turbo setups.

both bought ones and diy.

I´m talking all plumbing, ecu + tuning, engine conditioning if was needed. exhaust, exhaust manifold and basically the complete package
minus clutch.

When I mean bought I´m talking turn key drive away cost.

[Colonel Sanders]

im in around 10k at the moment and im still spending.
could have done it for alot less but i bought the best parts for everything to make sure nothing fails..

[Gunni]

Would you mind posting the parts and services you have bought and your current powerlevel.

[Colonel Sanders]

cant remember everything, but il try.

megasquirt in motronic box with wasted spark
3 msd blaster coils and msd coil wires
lc-1 wideband
holset hx40 16cm exhaust housing
equal length manifold with external wastegate provision, extra braced
tial 44mm wastegate
push fitting boost lines
boost controler
full engine rebuild, new shells, piston rings ect
weighted and balenced low comp pistons
weighted and balenced rods
balenced and polished crank
arp mains and rod studs
arp head studs
full head rebuild with cat cam turbo cam and all new parts
welded and oringed head
ppf adjustable vernier pully

50mm tial bov


there is loads and loads more, but il be here all day if iname everything i have bought, fixed, bought twice.
its all trial and error, and it costs a fortune...

More people??

the details of mine is pretty irrelevent on here but the cost is about £5G+ for the engine stuff before upgrading

[Phill172]

Even though I bought a complete engine/turbo set up, i have rebuilt it already with all new parts and had numerous machining done too.

Overall I have spent about 2.5k at the moment. But it depends how much power you want....

My list at the moment is.

Rebuilt bottem end with all new rod bolts and shells (2.5)
Turbo exhaust manifold (t3)
Decked pistons (7mm)
Welded head
Super T70 Turbo
Turbo cam & Vernier Pulley
Lifters and all other head components
Megasquirt V3.01
50mm external wastegate
Individual throttle bodies & plenum
Front mounted intercooler
Larger oil cooler
Remote mount oil filter

still have a few bits i need to decide and mainly injectors and clutch

Heres some photos
I know the wastegate as been attatched in a wierd way! But that will be changing...!

cost?

[daimlerman]

When I ordered my zone chip for my 2.7 build I spoke briefly to Ant on the 'phone.He commented that so many dream,but very few commit the cash....a high power engine costs big money,just rebuilding to standard spec. is costly.I would imagine that the cheapest turbo conversion is probably down to Toby Unna,but he is a very competent DiYer/engineer.

[e30_Turbo]

The initial "get boosted fund " was just £600, manifold, IC, Turbo, charge pipes + various odd bits.

To that I added MS, Injectors, WB and a few odd bits, all in all the first conversion cost me.....around £900/£1000

I've since spent many more ££ on many parts but the overall cost is less than £3k easy.....

I've also had two WB's, Two exhausts, Two Turbo's, Two IC's etc etc plus my boost gauge alone was over £200.

For someone who ' can do ' most themselves it's poss to do it very cheap, to pay someone else, say for 300/350bhp I would expect to see a bill for around £3000/£4000.

You could always ask Gadjit who much it cost him to get 383bhp @ 1 bar

[Gunni]

Ok, just wanted to see what the range is as I´m going to be building one engine that will make no less then 400hp
and then selling off as a package, i.e

rebuilt engine
turbo
manifolds
ecu
all of it basically.

basically a turn key setup fully mapped.
just needed a ball park to request for it when it´s all said and done.

[GrindCulture]

Chances are you wont get the cash you put into it back if you sell it once it's done.

[Gunni]

depends on the discounts you have where you buy your stuff ;)

There is not going to be 4k worth of parts in it, obviously selling for 4k would be sort of stupid if the cost is the same ?
Also 4k worth of parts would give ALOT more power that´s $8000, I´d expect no less then 700hp for that money

short list is
stock internals
ported head for improved efficiency
excellent exhaust manifold, split entry and equal lenght,
intake manifold if needed.
100% ideal turbo sized for 400hp and optimum spool.

the only reason I´m building and selling this is for research, experimentation along with paying for the research.
After my research I will posting as much info I can to better the community.

[Cloud]

Is the ported head really necessary?
Research is a good idea, and I think the turbo E30 will better the community for whoever buys it.

[Gunni]

the challenge is to try and create as an efficient engine as I can really.
that means port job and very possibly a cam.

The info from this will better the community I´m hoping and make people realize the potential a m20 has with the right mods and I´m not talking dyno queen dyno charts with no power below 3500rpm

[midnight]

well adding it up mine will have cost me about £5000, with a few great bargins ive picked up and thats prob gonna be a 450hp + build

[Phill172]

Have you checked out, E30tech? There is the biggest turbo section I have ever seen on there, so i mean you can always look state side for parts to if that makes it cheaper?

Also guys sorry dont want to be hijacking the thread. I was reading up on some articles and they quote 0-60's of 300rwhp to be under 4 seconds.....this right????
I mean thats serisuoly quick

If I was buying a complete rebuilt engine I would want some sort of warranty ! can you afford to rebuild it again at "your" cost if something goes wrong ?

Bimmerjim recorded a 0-60 of 3.2 secs when running 11.88 @ 110 mph.

That was with no more than 350bhp at the fly.

I'm well into the 5's with mine, so would imagine a setup with a smaller blower would do better as I get little boost in 1st, it waits till 2nd is engaged then rips my fucking head off! LOL

How would it be possible to claim a reason of a problem comes from the engine builder?

Obviously this would be fully mapped, dyno tuned and ready for use.
if nothing goes wrong in that process I can´t see anything going wrong from that point that can be blamed on the engine setup/tune.
Bad fuel and other issues obviously are not problems related to the engine setup.

Checked out e30tech? Yes I have alot.
I´m just seeing what this engine is going to sell for in the UK.

[daimlerman]

Without wishing to pee on your bonfire,where is your market? The type of guy who wants a motor of this sort is the type of guy posting,who is well capable of building his own,for whom at least half the fun is in the creating of a unique engine with more grunt than the last one. Could well be a market for a kit of tryed and tested components along the lines of A-techs supercharger kits...

Unfortunatley the person who has just spent "4k" on an engine may not see it the same way as you. If they did put "bad fuel" into it unknowingly and something went wrong, how would you tell ? If it wasn't sorted promptly, probably at your cost until the facts had been established, then you are likely to have gained a "bad reputation".

Serious??? I mean i was getting my head round all of this and thats Pagani Zonda quick!

I really dont know what to expect power wise with mine.....
just running a T70 T3 at around 1 bar.....maybe more if Ant lets me!

Issues with traction fozzy?

That would be with heated up drag slicks... I can't see many e30's if any on road tyres getting to 60 in under 4.5 seconds as there just wouldn't be enough grip.

Its not as if you can use your drag slicks on the road is it.

4k for 400hp engine is a damn bargain.
Tell me anybody in this country that will do

a complete rebuild
extract 400hp
engine management system
turbo
exhaust manifold
intercooler and plumbing
injectors
wastegate
and so on

for 4k.

to daimlerman.
There is no market, I´m just going to develop this one engine and then sell it of to cover cost. I have no interest in starting any retail business from this, This engine will create low rpm boost (1bar by 3k) and retain it upto revlimit(400hp).

Hope this explains things a bit

[oakey]

I'd be tempted if I had the money. I would without doubt want a warranty though.

[Gunni]

4k wouldn´t bring warranty, this would be considered a used engine, used without issues.

I used 4k as an example because it was a figure you had used in a previous post ! More K = bigger issues !

I'm not trying to pi$$ on your parade, just pointing out the drawbacks if it dosn't go quite to plan !

[Gunni]

Maybe I´ll buy a car to put it in and sell that, might be a better choice.

Jim was running a welded up 2.93 diff and slick tyres and having seen a few of his vids I bet my left bollock he warmed them right up!

What you all have to think about is he "only" did 11.88, there are a few e30's doing 9's so they MUST be doing under 3 secs 0-60 to make that sort of time. Street tires won't allow you do get anywhere near that as you would expect.

I did hear a zoner managed a 11.02 1/4 mile at the pod, away from zoners eyes, he must have hit a low 0-60 for that run!

Issues with traction fozzy?

Yes and No, If I want to have no traction I can, just press harder! There's no way I can have full chat in 1st, 2nd or 3rd without spinning up the wheels, 4th will spin up too but I need to provoke it. I'm only running 10.5psi and I can't see how I would want to go much faster really, I can't think quick enough as it is. When I get another daily to use the red ones getting stripped and boost wound right up, for nowI need it to get to work, hence why I'm such a wimp when it comes to things like the pod, I'd love to play but not at the cost of being car-less again.

Hi guy's

am new to E30's but have just got myself a very nice little 325i ....this one - http://www.e30zone.net/modules.php?name ... c&t=109585 Warren was planning on eventually turboing it and ive got the same intent.

im not after massive power just a low boost setup, for some sleeper fun but what are these engine capable of as standard? do i defo need to uprate headbolt's gaskets etc? or is forged the only way to go??

im used to Honda's and have put together turbo setup's for them built them etc etc so am capable of engineering a setup and fitting etc.

also does anyone have links to places for parts here or the states as i have ways of bringing in parts from the US of A aswell

mainly can it be done cheaply im in no rush and parts can be bought as and when they turn up i just need to know what parts etc im looking for

cheers for any help

[Gunni]

ARP head bolts and you can make your engine run 475whp in with stock internals.
Enjoy the read.
