Default 93 Volvo 240 b230ft/T5 build

Hey all! Iím officially apart of turbobricks! Iíve scrolled around the forums for
Months now, googling and researching. I was in debate, on either a B230f + T with T5 swap or a B230ft with T5 swap. (t5 swap coming after motor). Originally, I planned to square in the suspension first. Whatís left, is coilovers, adjustable sway bar end links (BNE has the order, just waiting on them to get the bearings needed), BNE trailing arm bushings, and the adjustable torque rods by BNE. Itís already got the IPD sway bars, BNE adjustable pan hard bar, itís on cut springs (previous owners doing), and bilsteins all around. I decided to post pone the rest of the suspension temporarily, due to a solid deal on a 91 740 turbo that runs and drives for $1200! (itís been impossible to source to a FT block or full swap here in Oregon, still need to meet the local Volvo club however. Been told those guys have spare parts up the wazoo) So thatís the plan as of now, get the 740 turbo donor car. Thankfully the owners holding it for me, and wants another Volvo enthusiast to own it. Otherwise, itíd be a B230f + T. So general run down; and I know thereís loads of info on these builds all over. But w, people coming and going from the site. Or better parts, tunes, etc. I figured this would be the most direct way to go about it if I have questions. This is my parts list as of now, if you have opinions/advice/knowledge to share. Iím all ears.

B230ft Swap/Upgrades:
My NA already ready has Lh2.4, ECU # 0 986 262 713. Havenít checked for EZK yet. Iíve read to use the 740 turbo computers though, my question is, since itís an automatic. Will that be okay? I have a manual m47, and am doing the T5 swap shortly after this. Which, does anyone else think itíd be easier to swap in the b230ft and T5 already mated? Or separate? I have one sourced locally, just need to pull it.

* Volvo 740/940 turbo ecu/ekz/ecm from donor car. (Coming from a 91 740 turbo wagon)
* Extended MAF connection
* Block mounted distributor/intermediate shaft from my na b230
* Isuzu NPR intercooler upgrade
* 3in down pipe/exhaust. Hood dump?
* High impedance injectors, other options as well. Blue part number: 0280155830 - 33.3 lbs/hr - 350 cc/min - 20į *SPLIT BEAM* spray pattern with 12ohm resistance. Red part number: 0280155759 - 30 lbs/hr - 315.3 cc/min - 25į cone spray pattern with 15.95ohm resistance. Site: https://forums.tbforums.com/showthread.php?t=301784
* Upgraded rods/pistons (now or later, undecided. Ultimately for motor life span and conditioning)
* @Redblockpowered: stage 1 chip or better
* IPD Billet HD Turbo cam
* Cometic head gasket
* Freshened up head/potential porting
* Boost controller (Turbosmart), boost, wide band, and oil pressure gauges.
* Potential turbo rebuild, or minor upgrade. (Brand new t3 maxspeedingrods turbo is for sale locally for $100, unsure of turbo company quality though)

How are the stock head studs on the b230ft?

Will the stock Volvo 740 turbo manifold work? Or do I need to grab a 90+, or different manifold? If the donor car doesnít have a +90.
Im going to get it on the 28th.

If I missed anything I need, let me know! I appreciate everything everyone has shared in prior threads. Iím stoked to get this ball rolling!

Here’s some photos, and bit of a history on my car.
I had zero intention of buying it honestly, it wasn’t until I really saw it. That I fell for the ugly little thing. Guy I bought it from just gave up on it before he could even change the wheel color. Drove great, rides alright with the cut springs, and well. It’s fun. Previous previous owner and I got in touch though, because he had to write me a bill of sale. The seller I met, never did any of that stuff. Thankful for that however, because now me and the previous owner who wrote me a bill of sale, so I could title transfer. Is now a good buddy of mine. Haha

Update! I got the 740 turbo! Drove up to Portland, and drove it on home. And it did great, i
Took a leap of faith buying it without seeing it first. Luckily the seller was honest, almost to honest.

I got my new sway bar end links, thanks to BNE or Kaplhenke racing!
Got some new, un crusty blinkers too!

My dad and I were talking about forged rods, and brought up shot peening the stock rods to reinforce them. Has anyone done this with stock rods and had good results?

The issue with the stock rods is that they are heavier than the aftermarket maxspeeding rods. So while the stock rods will take the power they aren't adding to the performance of the engine. Shot peeing works very well to strengthen stock rods and it would be a good process if you don't want to spend the money on the aftermarket ones. Personally, I would prefer to save the weight if you can.

Thanks man! I really appreciate your input. Iíve got a lot of questions, regarding small odds and ends like that. Iím rebuilding the motor, so I figured I might as well throw the maxspeedingrods and pistons in. Itís only going to help me out anyways!

Fixed those photos that didn’t work! Sorry!

One other small question, since I’ll be using my NA harness. I will need to use high impedance injectors, due to using the NA harness without the resistors. Right? Well, unless I found the wrong info. I was right, high impedence is what I want.

Yes, you can use V70 turbo injectors. They are high impedance.

Right on! Thought so.
Got my chips ordered. My dad pulled the trigger on them, because he liked that the seller had a list of recommended parts for this tune. From redblocktuning. Which leaves me with other questions.. I had my injectors picked out, realistically I’m shooting for at least 250-300hp. Chips good for 300hp. Recommendation is 465cc injectors.. but with the ones I’ve picked out. Can those reach 300hp? Or should I just run the recommendation. I don’t want to dump to much fuel, etc.. just when you think “I got this figured out, I’m onto the next thing”

Thank you! I was hesitant on ordering some parts until I knew for certain.

Update: I ordered a #219 EZK from J_wattsperformance. Unsure if he’s on turbobricks. But he’s big on Instagram. He really came through, just a real “what are the odds” situation. So I sent him some mula today. And now im deciding what next.
Got my motor stand, $25 locally. Left me with an extra $50 towards parts.

Update to this post: Ended up getting a black box chippable EZK, might actually take up the reins soon enough. To make these lil baddies. I’ve got 2 EZKs that need chipping, so why not? Might as well make my non chippable gold box, chippable..

And I’m iso of a 19t turbo for a fair price. I nearly bought a cheapy ebay one, but I can’t allow the weak point of my build to be a turbo.. that’s where all the fun is supposed to be had. Gonna make a thread on the wanted ads too!

Edit/Update: Found a 19t, 3in downpipe, and some green giant injectors for $375. Huge thanks to the people of turbobricks, just saved me about $200-$300 bucks.

Just a small update, not much happening at the moment. Other than some rear inner fender work. Got rid of all the rubbing and it’s been so nice.

So after some thought, and looking at my goals, drive train, etc. I’ve decided to reassess my build. And I’m happy i did. I was trying to bite off more than my drive line could chew for what I’d like to use the car for. So I scaled it down a bit. So I’m going to call it my own personal. Stage 1.5. Lol. It’s my look at stage 1, along with getting prepared for stage 2.

Ecu: 9xx ecu, have 951. Could work, but causes “issues” some said. Need a turbo 9xx ecu
Ezk: Have black box ezk, with chip able daughter board.
Chip/sets: Stage 1 fuel/EZK chips. Have stage 2 on stand by.
Internals/Bottom end: Forged rods/pistons. Why - I want to be prepared for stage 2, once I get the T5 trans & 8.8 axle. And “endurance” reasons.
Cyl. Head: IPD cam/gear, or similar. Cometic head gasket. I’d love to do yoshifab beehive springs. But that’ll come later with porting. Going with new oem valve springs, etc.
Exhaust/DP: 2.5in DP or 3in DP, opinions? 3in straight pipe, to either flow master, or similar.
Friend has an apexi n1 he said we could throw on, don’t know how I feel about that though.
Turbo/IC pipe: rebuilt 13c, eBay kits any good? New kinugawa CBV/waste gate. Braided lines/AN fittings. Want to remove hard line from radiator. Fitting size? 2.5in exhaust pipe for IC. (It’s easier to weld on) I have a 19t, just don’t know how it’ll agree with these injectors, etc.
Injectors: Red #0280155759 Flow rates @ 43.5 psi / 3 bar
31.4 lb per hour
237 G per min. (N-Heptane)
330 cc per min
15.95 Ohm resistance
Spark plugs - NGK BPR7ES
Why - want to run high impedance injectors on the NA harness. I’m following the guidelines of some +t builds for simplicity. Have OEM green turbo injectors, and resistor pack on donor car just incase. Sending both for cleaning. Green giants, on stand by.
Amm/MAF: 016, and have 012 on standby. 3in intake/cone filter. Plus, extended maf/Amm connector.
Cooling system: NPR intercooler, bigger radiator from 92+ 940 n/a. If running 951 ecu, I’ll need a manual 2 speed electric fan switch.
Oil cooling: Can run oem oil cooler, or aftermarket alum oil cooler and relocation, braided lines. Location - behind grill maybe? 30 row I was loaned to see how it works. To big a cooler?
Gauges/Controllers: •Turbo smart manual boost controller/gauge. AEM Wideband, Or? Jegs Oil pressure gauge, or? And digital voltage gauge. Swap overs: block mounted distributor/intermediate shaft from my na b230
Clutch/Trans: M47, Sachs K70029-02
Driveline/mounts: Either ensure the 2 piece is functional 110% or go to a solid piece shaft. Ensure trans crossmember bolts are straight, maybe go up one bolt size *the rubber grommets ripped from prior owner not putting in washers. Little more rigid mounts possibly?


If anyone has suggestions, I’m all ears. Or corrections. I’m going to start some online tuning classes as well. I’d really love to be able to tune, and burn chips. And do it in a variety of ways to help contribute. So far the plan is to use ostrich/tunerpro. And they have a 2burn program so I can share the tune! From my understanding, that’d be the most user friendly. And good for starting. Until I need a stand alone.

Oh, and what is anyone’s opinion on td04 13c rebuild kits off eBay? I’ve seen a few decent looking ones.

Have an update, I’ll have to get back to that so stand by!
I do have a question, since swapping in a B230ft. And using an NA harness, all lh2.4. How necessary is it to wire in, and use the ATS, and the cold start injector.. how would I wire it in if so? And what happens if I don’t? I didn’t want to start a thread on this, when I can hopefully figure it out here. I’ve been looking on all the knowledge I can find for this. I have a turbo harness, I was just planning on using the NA one and treating it partly like a + T.

Thanks to any who may know or can help.

This one on Amazon has posts indicating it was used with Volvo/ Mitsubishi 13c

I'd use that as reference & look on eBay - should be available for less for name brand versions. I used Kinugawa in the past (15+ years ago), no idea if quality is still there on Kinugawa.

If you are rebuilding this yourself, read this step by step instruction guide (in my dropbox) - I got it about 15 years ago - it covers everything you need to be aware of.

If you are adding the CSV wiring for the B230FT from the 740 to the 240 harness, just follow the wiring diagram for the MY 740 - that will give you the ECU pin locations.

Example - you can see the CSV (#188) is wired into the injector feed wiring - the ground leg is the control - in this diagram it goes to pin 32 - this might be for my Regina setup, I didn't label the diagram. You need to make sure you are looking at an LH2.4 diagram is all



Only Regina/Rex cars have an Air Intake Temperature Sensor (#185) (is that what you are referring to as ATS?) - that, coupled with the MAP (#440), take the place of the MAF used on LH2.4, which incorporates the air temp, so no separate sensor for that on LH2.4

No worries about cold start valve. Just leave it disconnected. The turbo ecu provides fuel enrichment on cold starts.

Thank you for the input!
I was wondering about how the car would handle cold starts without it.
When does the cold start valve become necessary ?
And man, the red top injectors cleaned up nicely! Thank you again.

I am rebuilding it myself, I got a real genuine Mitsubishi rebuild kit! I found someone to potentially rebalance the 13c for $60 ish. Just need to send in the rotor assembly pretty much.

Even though itís a Regina chart, it gives me a baseline idea. So Iím thankful for that. Iíll look into it more, and see how things go. This is a knowledge Iíd like to know for that ďjust incaseĒ situation.

There is no need to rebalance the 13c. Larger turbos, sure, not the 13/15/16 sizing used by Volvo - IF you mark the existing locknut/shaft/wheel & put everything back EXACTLY as it was.

Areas that HAVE to be spotlessly cleaned:

Remove all coking from the shaft & housing

Thank you again! This I didnít know, I wondered about it though. It only makes sense that itís already pre balanced.
Iím going to hit the parts store tomorrow AM for some parts cleaner.
Iím currently looking for the rebuild specs/torque specs now.
Iíll get my photos uploaded to photo bucket too, for a good update.

So update, finally. I switched over to to another site for hosting my URLs. Hopefully it works better.
So far starts, I got the injectors cleaned and rebuild them myself with new screens/caps/O rings.

https://flic.kr/p/2mwEn9H
https://flic.kr/p/2mwEmye

short update, just making sure the photos work before continuing.

Well I guess leaving the URL will work for now.
So furthermore, I’ve got the motor out and tore down. Mostly, need to do the head tear down still. Here is a few photos, of the worst main bearing, cylinder, valves, and so on. Not all looked bad, but someone definitely let it sit with water in the cylinders. So im going to get my measurements, and see what size piston we will need. Anyone know how wiseco pistons sit with the cxracing rods? I got them in, along with just about everything else for the bottom end. Give or take a few things.
Worst main:
https://flic.kr/p/2mwFq4Q
Worst cylinder, by looks:
https://flic.kr/p/2mwFqgi
Bottom of head:
https://flic.kr/p/2mwAE5r
New rods, still need to double check dimensions:
https://flic.kr/p/2mwFq5X
I¬’ve got a few other things done too, like an10 oil lines, etc. But we have all seen, and read about those hahah.

Im more likely, while waiting on pistons once ordered. The plan is to do my abs delete, and dual rear caliper install. The abs unit is starting to have intermittent issues, so no better time to do an upgrade! I will share how that goes. My bosses have been really getting me some good hours, for the sake of this build. The hard work is paying off though!
