Impressive !

Generally, at what mileage this B230 FT and FK can run before need to do engine overhaul ?

And for the overhaul, need top overhaul or full overhaul?

Thanks

Change all fluids, fix all leaks, replace worn suspension components. Replace soft engine and trans mounts and driveshaft support.

I didn't detect any bad vibrations after removing the frame weights.

Depending how often previous owners changed oil and amout of cold starts, but over 300 t miles is nothing special for Volvo.
Opened one B230F and piston ring gaps were in factory specs after 350000 miles. Cylinder walls were quite shiny, so new rings and honing was performed.

And of course, high mileage engines are often full of sludge and carbon so it doesn't hurt to open engine.

Yes, several sources, Skandix and most euro parts houses have them. The rods I took a look at, but could not find any clear markings, possibly they were volvo specific, many have ran chinese H-beam rods with succes here. The pistons are Mahle.

The original Mahles are getting harder to get. I had to order mine from Skandix just a few months ago, because they weren't available at the local volvo dealer nor the Mahle importer any more.

Kms for overhaul can vary greatly. I had to bore the block of my B230FK to OD at only 355tkm/220k miles. Then again, the last 130tkm (at least) have been on higher boost level, bigger turbo, occational track days and so on. Also, judging from the carbon deposits i the head I noticed after I got the car, I would guess service had been semi-neglected at some point. My B230FD seemed to be in a bit better shape with the same milage.

If you are planning to replace the pistons, I would suggest you have the block measured before you order new pistons (in case you have to go OD).

Thank you

about D088 intercooler, it's so expensive when it reach my door. currency exchange rate, shipping and tax. i understand do88 intercooler is good

can i use fmic, mounting the fmic at lower bumper air opening. at lower bumper fitting location, the fmic not blocking fresh air to aircond condenser and radiator.

the promblem with low fmic mount, the intercooler piping will be long, and i afraid of turbo lag. most aftermarket fmic have 2.5" in and out. can i tapper down the intercooler in and exit from 2.5" to 2.25" , so that air in intercooler system could easily fill up the smaller 2.25" piping...with hope the smaller fmic piping reduce turbo lag. Is this theory ok?

thank you

KL Racing Intercooler is almost half the price and while I haven't tried the do88 one personally, I don't think the upcharge is really worth it.

I'm not really following your thoughts about the piping or mounting, your car should have a stock intercooler anyway.
The aftermarket units just swap out with some minor work on the rubber mounting brackets.

KL carries both versions, AC and non-AC:

Also, I made a topic on it a while ago: http://forums.turbobricks.com/showthread.php?t=343520

A bit more road noise for sure in my experience, don't touch the one on the firewall, it will result in a lot more noise. The frame rail ones were acceptable for a daily to pull, the firewall, not so much
