Most people are using GT series turbos to obtain that hp. What model is this engine going in?

 

The project in it's planning status now. I can pick up 9000 turbo engines from salvage yards. What model year should I buy? The engine will be from a SAAB 9000 CSE? (Full Pressure Turbo, not aero) 2,3L.
I know that people boost up their saabs with GT series but it's too expensive compared to the twin K03-s.

 

the b234r and b234l are the same mechanically except for a different turbo.

 

Thanks for the info. Are the stock pistons strong enough to cope with 400HP? What is the safety limit of the stock pistons?

What other modifications do I have to make to produce that power reliable?

 

Pistons and rods are fine for that amount of power.

If you go with a Borg Warner turbo expect to do some custom tuning as nobody that I know of has run a K series turbo. No one has done a twin turbo setup to my knowledge either.

You'll also need stiffer valve springs and solid lifters to replace the hydraulic lifters. I would suggest running with a GT3076 as its a proven turbo and would deffinitely make your exhaust work easier as well has hitting your power goal. I have a feeling that even if twin turbo'd by those k03 turbos that the k03 may be similar in flow to the t25, don't know without looking but there small to. The t25 can't flow the proper air flow as it'll be outrun by the motor. It wouldn't be able to do it in twin turbo either. 21psi from a t25 twin turbo or not isn't going to have anywhere near the airmass as 21 psi from a GT3076 and I would bet the same about k03's as well. Especially where your considering to run this motor in the rev range.

 

I've put up a K03 turbomap plotted for 2.3 16V (twin turbo option) http://sanyapower.atw.hu/K03-2072.jpg
The only reason that I decided Borg Warner because I can pick up the two K03-s less than 1000$ around 850 - 900$. On the other hand you are right, the exhaust work costs more than a single turbo option.
How much does a GT3076 costs?

In the afternoon I also plotted a K16 (twinturbo option). It charges later because it's much larger than the K03 but compress air much more (29-30psi) and also delivers more air into the engine. http://sanyapower.atw.hu/K16-2467.jpg 2900rpm - 6900rpm

 

Kaylan(aerodynamic) put something like 475whp on stock internals, but had some, still having? HG issues. You WILL need bigger injectors.

The real prob is between the clutch and the wheels. The transmissions are not that strong.

 

Yeah the tranny ... How much quarter mile races could it stand without problems?? The vehicle weight will be around 550 - 600kg without driver(mid engine-RWD).
The tires comes from Hoosier tires D.O.T. Dragradials 295/65 R15 size

 

Saabs arent really meant for 1/4 mile races. On the highway you wouldnt have a problem keeping up with the new corvette Z06, vipers, or other slow cars like them

 

You might try a bmw e30 transmission. Goran got them to line up.

 

Hmm .. a different transmission, I didn't think about it yet.
The only matter with the BMW tranny it's layout. It's designed for longitudinal engine alignment.
Maybe you are right if I think about it, the stock transmission isn't capable of that much power.
Longitudinal option ... I need to search for another chassis
The longitudinal engine alignment has a problem, Less weight on the driven wheels means easier wheel spin, slower 60feet, worse Quarter mile time

 

You say hybrid, what type of hybrid are you building, and what you say b234r, I haven't heard mention of what you're going to use for a vehicle... Any more info on this?

People are assuming you're using a Saab chassis for some reason, when you say hybrid drag vehicle, and getting a 9000 engine, it would seem you've got other plans.

 

You are right.
My plan is:
- pre 1989 Trabant chassis (weighs aroung 200kg!!!) (two stroke)
- Saab B234L powerplant
- Middle engine, rearwheel drive
- Lot of work to make them together

I intend to use a B234L engine from a saab 9000 with bottom end.
In the cylinder head need to change the lifters & spring for the higher rev limit.
Fuel rail & exhaust side plans mentioned above.

Whoa, this is a wicked cool project. I only ask of two things, Pics and Videos.

 

As soon as the project started pics&vids will come

 

out of curiousity, where would you be able to get mechanical lifters for a b204 and would there be any modifications needed besides camshafts and springs.

or, for $500, find a used holset and buy a 10cm^2 exhaust housing. decently low spool, but will still make big power

 

I have read the rules again, the drive shaft can go through in the passenger cell of the car if it's completely separated from the driver. . . so front engine RWD can be an option.
The only matter is the weight ratio. With battery relocation, fuel tank relocation its possible to put on more weight on the rear wheels. How else should I put more weight on the rear wheels? (Without put extra weight into the car)

 

Someone help me pls.

I found an E30 BMW with SAAB engine, but the forum is swedish, and I can't translate it
The vid. is on youtube.com

, the forum is www.cannonballforums.se

Need info on which tranny they are using, what modifications did they do in the tranny, how did they connected to the SAAB engine.

 

that would be goran...

here's his thread over here

http://saablink.net/forum/showthread.php?t=24247&highlight=bmw+saab+engine

 

The problem is thats no information on the gearbox type, only guesses
Goran only put up some pics of the ride, but didn't answer the questions.

 

I have often wondered if they would sell the solid lifters, but have never gotten as far as calling them. Do you know they sell those or just guessing?

I was thinking that might be a racing secret, but who knows...

John

 

If they were a racing secret why would they list them in there product section. I'm sure they are available for sale. Just gotta get a hold of them.

 

im guessing thats the only place to get the lifters and does anyone have any idea on the pricing? would there be any modifications needed to the head or would they just be r&r. swap em out and good to go. well in combination with the camshafts and valve springs of course

 

The price of those lifters is on that page. Its just listed in Sweedish Kronor. However I think thats the cost per lifter so take that * 16 to get your total price pre VAT.

 

yeah i saw the price and was wondering if someone could translate it for me. im sure its way to much but just curious

 

There is a Peugeot lifter that is compatible. I personally did not want that last 2/10s and like my self adjusting lifters.

 

What do you mean last 2/10s?, The last tolerence in the head? Not sure what you mean.

First thing to remember is that you would need a turbo and set-up that will make good power up that high in the rpm band.
