V70XC 98 not fast enough!!

[Glencoeteen]

Did any of the Volvo's come with the 15G? would it be a bolt on? i was just thinking id have todo an IPD ECU its supposed to jump my power from 190 to 230hp so 40hp gain would be great. i don't want it to be a street racer i just want it not to be so sad when its full of people.

I agree about the 2.4 turbo is not as strong as the 2.3 when it comes to rods. I would go no bigger then a 15G get the ecu tuned set your cam timing, and a turbo back exhaust like OBX one. that could get you around 240hp, 250- 260tq at the crank.

all the 850s with a 2.3 came with a 15G. I think I have like 3 laying around. The tuner I use is pretty good. your tune would be $300 gets you 229HP and 250 -260 torque. and thats with no other mods. Hes located in Oregon. http://www.inmotionusa.com cheaper then IPD I believe. and I think its better. my car runs very well. 13.6 1/4 mile. sometimes I forget when i have 4 people in the car because the torque seems endless. advancing the cams makes a huge difference in low to mid range. the exhaust comes factory a couple degrees retarted. that needs to be corrected.

My 2000 XC has had a 15G turbo coupled with an angled exhaust housing from my original 13T, plus a 15 psi T5 tune from Speedtuning(had to send my ECU so that it could be rechipped). I am about 6 months and 4,000 miles into this setup and the car is my daily driver.

Several others on Volvospeed are running 15g/16t turbos on their LPT+T5 tunes without issues. Some advocate using T5 injectors, others have been successful with the original LPT fuel injectors.

I can see doing that, but it MUST be reprogrammed first before trying to drive it with the bigger turbo. The extra boost from the 15G opening the wastegate at low RPM's like the LPT engines are designed to would absolutely destroy connecting rods under 2000 rpms. At least that's my theory. I think at the higher end, the engines can handle quite a lot.

and there we have it. and how much quicker is it?

this is not at all true... there is a guy on volvospeed/swedespeed(a former volvo dealer tech at that) who has been running a 15G turbo on his 2000 s70 AWD with his stock ECU for months now while he is saving up for a tune. 2 others(including myself) ran 15g/16t turbos for a week or two with the stock ECU while arrangements were being made to have the ECU rechipped. my car was 100% driveable with no issues whatsoever.

as for how my car runs with the 15g+15 psi tune, i rarely ever have the need to go past 10-12 psi while driving sanely, but it's nice to know that the additional power is there.

The 2.4 L engine cannot handle the boost of a bigger turbo - Volvo already put the biggest turbo they could fit on it without bending rods.

There are a few things you can do to increase the HP (stage 0, K&N filter, fiddling with the wastegate, etc), but an XC is no race car. The R is heavy too - I can't really feel a whole lot of difference between my T5 and the R i have driven. It launches faster though

jablackburn-I'm picking on you because the board only lets me quote 1person at a time. No offense meant, just do your research next time:

1) YES the 2.4L, or "2.4t", the stock LPT engine CAN handle a bigger turbo! The 13t is no fun at all, at the very least use the 16t (which is the turbo found on the T5 series 01-04 vehicles), but you can also bolt on the 18t or 19t (found in the 04 R, 05-?? T5 series).

2) NOT ONLY can you make more power with a bigger turbo, but you will comparably make MORE power than the HPT series vehicles. I.E~ if you put in a 16T turbo into your vehicle, and chip the car, and you were to compare your dyno to a stock T5 with the stock 16t, also chipped, you will find you are making more power. Why? Read on.

3) Unless your goals are 300 or + whp, you have no worries about your rods*.

4) The rods in the 01-03 LPT and HPT are the same.

5) The compression ratio for the LPT is higher than that for the HPT. This basically means you get more torque, more power, and more low end then the HPT makes. It also means you can't run the same boost levels (stay below 20psi). NONE of this matters in the 01-03 cars, because the rods are going to start turning to spaghetti @ ~330whp, so both the LPT and the HPT are capped with stock internals at that number.

*NOTE ABOUT ROD BENDING: you can bend your rods with the stock turbo - it's been done. You need a proper tune, boost control, stage 0, proper gas, etc. in order to avoid rod bending.

So, to summarize, ignore what these people are saying. I have done this, and run it safely, and can point you to a dozen people that have done the same and had the same results.

/rant

my advice:
- upgrade turbo to 16t
- upgrade exhaust to 3" downpipe, minimum 2-1/2" catback
- tune (ipd, speedtuning, others...)
- upgrade suspension (springs, struts, sway bar, bushings, strut mounts, strut brace - all found at ipdusa)
- get performance tires and wheels
- stage 0

*IIRC your brakes are already 302mm, if not I would upgrade your brakes

Have fun.

OK, good to know for future reference

I usually stick to fixing things and don't comment on the whole tuning thing since I don't know much about it or have no interest in doing it to mine.

The general consensus I've heard from folks is that the older-series 2.4 N/A (and I assumed the 2.4 LPT) engines cannot handle a lot of boost, but I guess I've been proven wrong! I was going on the theory that since the compression ratios were already higher on those engines, more boost from a start would tear it apart. Mine's a 2.3, and I've never had any experience tuning any of the others.

yeah thats what i was thinking.. just installing a stock T-5 turbo from a 98. i can get one for 150... and i know about ipd its only a 30 min drive for me to get there. i got everything from them todo my stage 0. my main goal is just to make it more fun to drive in power aspects 190hp is in all terms lame for an awd. honestly 190 should have been the stock power. i would love to see around 240ish 250

Interesting. So a 16T would keep you under 300 hp? I definitely do not want to break anything but I would not mind a bit more juice. If you replace the turbo do you HAVE to do the exhaust at the same time? I can see why you would need to but I have to ask. So for a '98 you're saying 16T, exhaust, 93+ octane gas, and the other stuff you would expect to do? Also is the IPD ECU tune absolutely necessary or can it be postponed?

Thanks for the insight.
