I was wondering if the stock 850 GLT has a turbo. Thanks

Nope. The 850 turbo, R , and T5-R had turbos. I believe the volvo S70 GLT had a low pressure turbo but not the 850 GLT.

Actually that's not quite accurate. The '93 and '94 Volvo 850 GLTs definitely were NA engines. I don't remember if it was 95 or 96 but the GLT became a light-pressure turbo a couple of years after introduction (I had a '94 850 Turbo and '98 S70 T5 around that period.)

Actually we were both sort of wrong. The 850 had the low pressure turbo only in 97. The name switched to S70 the next year. My dad had a 96 GLT and it had no turbo.

GLT no turbo. 97 yes...last year.

I have a 97 850 GLT and it is what the dealer call it Mini Turbo.

I've never heard it called a mini turbo before but the '97 GLT does indeed have a light-pressure turbo (from Mitsubishi.)

I believe the LPT (low pressure turbo) motor uses a 13g at around 5psi. Where as HPT (high pressure turbo) uses a 16T at about 10.3psi.

OK. So, does anyone know what the 850 GLT 190HP low psi turbo became in 1998 (V70, V90, etc)? How about the 850R for that matter? Thanks.

It became the S70 (GLT). The 850 wagon became the V70. The 850R was not continued in S/V series cars until the 2004 S60R / V70R came out in 2003 (both on the newer P2 platform that replaced the older 850/70 series platform.)

I have a 97 850 glt turbo well it is my wifes car but she wants a new one. I like this car and want to cean it up but can I improve the performane with a chip and such or is it a not very responsive to modifications

Go to the 850 forum at Swedespeed.com or Vvspy.com and you'll find MANY enthusiasts who have added TME/IPD's chip, Wetterauer's, SCT's, BSR's, etc.

The short answer is yes - a chip makes a big difference with turbo Volvos, even the low pressure ones like the GLT.
