: I Think I'll Give Up
9th March 2004, 02:03 PM
I think I'll give up with the idea of fitting a MBC to '99 9-3se lpt.I've been told by Abbott that it cannot be done.I do not have a BPC as this is controlled by the ECU.All I can do is an ECU upgrade which they offered me 200 bhp for £250.
Thankyou for everyones help and input on this subject.You know who you are,Dead Centre,Boxman,Aero and Spatl.
Ray (Greeny) :cry: :cry: :cry: :cry: :cry: :idea I think I'll go and buy a Viggen

all you need is the ecu from a FPT and the BPC unit from a wrecker and you can install these easily. Its a very easy upgrade. Only thing that makes your LPT different from the 185HP version in the ECU and BPC solenoid.

No problem mate.
Sorry for not being around of late. 5 people were laid off at work last week. Nervous times ahead :roll:
To be honest I have not fitted my MBC due to the Boxman having bad times. I think i'll load it back on ebay and wait to get a Dawes or simillar.
Next job for me has to be the Konis and Eibachs that are sat in the shed. Just need new mounts and bearings for them.
I got a complete pair of 93 headlights for £35 of ebay the otherday :cheesy:
So thats this weekend soughted. Oh and I still have to fit that headgasket that Munki showed me how to do. Oh and yep there is still a list :lol:

You know, SQR-900T has a great point. The only difference is the two items. There is a saab junk yard here in ATL that you can check with or I could check for you. The website is
www.english-swedish.com you can give them a call as I know they have tons of ECU's laying around as well as BPC's. What I would not be familiar with is whether or not wiring needs to be run, but I can check with them as they are in my area. If you want me to check it out, I can talk to the Saab Doctor up there, his name is Chris and he will know what needs to happen. PM me if you're interested in me finding out. Obviously, the ecu would be easiest, but I still don't understand the deal here. I have fit many MBC's on LPT's in the past where the BPC was in there so your setup is different for some reason.
OKAY: Just got off the phone with Chris from english-swedish. Greeny...what car are you driving? is it a 9000? or a 900?
Some 9000s were equipped without a BPC and the turbo was connected straight to the wastegate. If you're running a 900 or 9-3, they all have BPC's. SO, if that is the case then someone has disconnected the BPC and bypassed it.
If it is a 9000, the information from Chris was that the car is prewired for a BPC (APC Solinoid), therefore you can add it if you'd like. He gave me a price of a BPC with all the hoses for $75. If you're interested, give him a call off the website.
BUT, with or without a BPC, you can do it. You would replace the existing hose coming off the turbo compressor with a longer hose connect your MBC and then another hose going to the WG. It can be done, definitely! End of story. Your game...

I'll go and buy a Viggen
As my 100th post here on Saab Central it is fitting to voice my philosphy to your final statement:
I say, better to build your own race car then to buy it!!!

Someone just let me know that English-Swedish Spares website is down at the moment so I figured that I'd post their Phone Number: 770-475-2662

greeny greeny greeny where has the dunkirk spirit gone :-?? dont give up now your on the home run, yes i had problems with my MBC but thanks to spatl that should be sorted soon, all the BPC valve does is control the amount of boost pressure the WGA sees :! all the MBC does is control the amount of boost pressure the WGA sees :! to fit a MBC you do away with the BPC sol any way so all you need to do is as spatl said and replace the hose from the turbo to the WGA with two longer pipes and fit the MBC in the middle and then the world is your oyster as they say :cheesy:

SPATL> Hes in the UK, they had a 150 HP LPT version of the 9.3 over there. We didnt get it on this side of the Atlantic but the idea is the same as the LPT 9000 we had.

hi greeny glad to see you've changed your mind if you need pipes i can probably find you some,if yoiu let me have your address i'll send you some i have 1or2 9000 apc pipes sets kicking around.
10th March 2004, 11:18 AM
Ahhh Thanks SQR-900T. That clears things up. Definitely still can be done, but gains will be smaller, but still worth it.
10th March 2004, 12:59 PM
does any one know the fuel cut pressure on a lpt :! i wonder if it is lower than the fpt
10th March 2004, 02:50 PM
I think its around 15.5 psi
10th March 2004, 04:19 PM
Can someone tell me which models had the 185 bhp fpt T5 engines in. :-??
11th March 2004, 04:50 AM
ng 900 94-98 9-3 98 and 99 stephs 98 9-3 is a 185bhp and they are pritty quick,even quicker when i get my dawes MBC fitted :cheesy:
11th March 2004, 10:40 AM
To add to Boxmans info, '99 9-3 base model and 9-3SE automatic trannys were 185,
11th March 2004, 10:43 AM
Yes, they couldnt make the 99 9-3 SE auto's HO now could they... :x
13th March 2004, 12:55 AM
What kind of idiot would drive an auto 99 9-3??? :cheesy: :cheesy: :cheesy:
No, I've always wondered how they handle turbo lag. I've heard some reviews state that Auto was the way to go to manage the Saab turbo lag. Others, of course, say "This car should only be driven in 5-speed form."
Ah, autos can be pretty convinient some times! Wait till you have kids Stalker!!!
