Hi Guys, I'm relatively new to the whole 340 tuning game. But i've researched a little and found that the "B14 4E" in my volvo is the same basic block/head as a renault 5 gt turbo. Now i have a friend who is majorly into his old renaults (5 turbos/ 19's / 21's etc) ...He has offered me a 212bhp (proven) 5 turbo engine that he built himself with strengthed bottom end, etc etc

I see a guy from sweeden? (anjo?) has fitted an R5 Turbo lump to his volvo. BUT i hear that being Left hand drive it will fit. Now obviously my car is RHD and i've heard that the turbo will foul on the brake servo etc.

Can anybody confirm this? I am an engineer by trade so making parts to get around this is possible. but I need to know what issues i will face before i buy the engine etc.

He has offered me the engine, clio alloys, clio clocks, clio exhaust etc for £200 (mates rates!)...Obviously the exhaust would need cutting and modifying and i will probably need a better gearbox than my 4-speed item. But if this can be made to fit it will give me the power i want in an awesome little car.

Thanks in advance for any help you can offer

Cheers Tom

As with all conversions in these (RHD) cars, the steering rack likes to get in the way of the exhaust downpipe routing. (Was the same when I built my 360 turbo.)

Unsure about the brake M/C being an issue on the 340's though.

I love R5 GTT's, and your mate sounds like he knows what he is doing to have extracted a healthy 200 BHP from one. [joke] Does it come with wingnuts on the head bolts? [/joke]

Best bet imo is seeing as you know the engien will physically fit without too much hassle, then just bolt it in and see what's what. Any issues you come across will not be major!

Haha, yeah he has told me the stories of problems with them, I guess I will need to make a custom downpipe then? It has an aet updated turbo on. If I custom made a downpipe to clear the rack would everything else work? Can I get a 1.4 5 speed box? Or do I use 1.7 5 speed box? Will wiring from the Renault match up to the 340 do you think?

Thanks for your help

Dunno much about 340's mate (or even my own 360 ) but I'll have a bash seeing as no-one else is here atm!

Definitley gonna need a custom downpipe. You will be able to route it away from any obstacles. All of the gearboxes are the same on both 340 and 360 as far as I know, well apart from the obvious 4 and 5 speed differences.

Dunno about the wiring, i assume you will be running the carb? There will only be a few wires. Ask Anjo? He no doubt will know what is and isn't needed and where to join the looms. Failing that, then it's wiring diagrams time. Just get a pinout for each engine and see what's what. No doubt I am telling you things you already know though mate!

Oh aye, bigger turbo's are always more fun! I will be interested to read the specs on this one. Will make your 340 into a nice little weapon!

^info in there. Though Anjos is LHD so youll have probs on top as you already know.

Nice plan though. Sounds cooler than the other side of the pillow.

That's excellent help mate thanks , in my local Scrapyard is a 340 1.7gl 5 speed. I can get the box and diff cheap and if that will mate to the engine will be excellent. A custom downpipe won't be a problem and wiring aside I hope it's that easy.

Don't like to sign up with a million questions like but I really want to get my 340 sorted before next show season, which is tricky as I'm also converting my Astra van to a bigger turbo and 150+bhp from a 1.7 turbo diesel

Thanks again for your help mate

Not an Isuzu 1.7 td surely?!

I've been reading anjos thread for a while, I must say it is gorgeous! If mine turns out to be 5% as good as that I will be a happy man! Cheers for the link

It's a 54 plate 1.7cdti isuzu yes, it's pushing 130bhp ATM but should be over 150 when I fit a Saab gt1752 turbo and a better front mount

Get in. I had one in a Cav with vauge dreams of tuning. Never got round to it though.
Good engine that.
Get some pics up. Sounds intresting.

He's new school Ben. This one don't do chip fat!

Yeah this is that same basic engine 1686cc but ferried by Vauxhall with a common rail injection system and a bit more refined, 81bhp out of the factory,

Made at Vauxhall, perfected in my workshop haha, I'll put some pics up when I'm at home on my computer, it's my pride and joy but I've always wanted a 340/360. My uncle has a 360 in grey with about 22k miles on it, won't sell it me though haha

oh yeah. its got letters on.
a C, a D, a T and an I.

Pics still warranted.

Hello Tom, welcome to this forum!
cheers for the compliments on my car, i can basically scetch out for you what needs to be done for a 200bhp engine in a RHD car

lets start with the clutch. i currently run lower boost than the setup is made for because the strengthened sinterplate clutch doesn't hold, my new plan was to bolt a renault 5GTT flywheel on with strengthened pressureplate and then again the sinterplate that fits the V340 spline pattern. that should hold to about 400/450Nm

biggest problem with this is that the starter teeth on the flywheel are on a different place compared to the 340's flywheel but a adaptorplate for the starter will solve that. then there's the smaller problem that the TDC sensor on the bellhousing is also on the wrong height (and i also believe that the TDC sensor on the r5's gearbox is straight up; TDC sensor in the volvo is about 20degr to the lh-side so another thing to account for though i personally thought that's nothing a custom bracket or trigger wheel on the crankshaftpulley wouldn't solve.)

then there's the exhaust; standard and uprated manifold's that fit the R5 are useless as they place the turbo behind the engine and there really is no place for it there. a custom exhaust manifold is the way to go; but this will be one of the most difficult things of the entire build due to the RHD, it is definatly worth while to get that right as a proper manifold definatly benefits the turbospool

wiring it's very simple, everything that's 340 can be used. just make sure you route the 2 wires to the starter different, so they don't melt from the exhaust pipework
on a very important notice you do have to swap the entire Renix unit for a R5GTT one (code 208 or 209) as a std B14.4 Renix isn't made with a boost-curve so you can potentially blow the engine to pieces. you can also bolt on a knock-detector from a phase2 R5TT and wire this to the renix aswell; that also saves you quite a bit of work!

i personally find a rev-limiter a big must for this engine as when i drive in the wet and when it starts to slip it'll rev to the limiter at 6500rpm in the blink of an eye. also i personally prefer to use the 340 front end of the B14, so B14 waterpump, alternator, brackets and pulley's. you will also have to make new engine mounts as a B14-T will rip any original mount to pieces in no-time

i might have forgotten some things but the most imporant bits are here, i frequently look here on this forum so feel free to ask

oh and my own B14-T is/should be making about 200bhp atm though i never dynoed it (tuned it to 1,1bar on my own AFR and EGT gauges; will dyno it after the injection-conversion is done) compared to other cars with likewise power it should be there, i can keep up with my mates STI Impreza and a standard B14 won't get you there i'm allways curious for a speclist on the engine he's build; got any pics/more info on that?

*Bows down sir*

Thank you for your advice mate. That is starting to clear things up nicely. Only thing i may struggle with is getting an exhaust manifold made...All the other bits don't sound too bad tbh.

No doubt i'll be picking your bain much more if you don't mind ...I'll get a full write up of the spec when i next go down and see him (possibly thursday) and i'll try get some pics from him then. I believe he had a few clutch related issues with it in his R5 (eventually the rot got in to it, so he stripped it and bought a lexus soarer drifter)
