ta for that i might screw that idea and just run a low blow turbo setup lol i think it would be simpler

[Forg]

A turbo conversion probably isn't that much simpler; most people assume you're turbocharging when you talk about twin-cam conversions 'cos the factory twin-cam Volvo engines didn't offer much more power than the SOHC ones.
You're certainly more likely to get more power turbocharging though, you can get ~140hp just by mixing-and-matching cheap factory cams & heads in n/a form, then a low-blow turbo setup will simply add to that (that's versus the ~150hp the factory twin-cam engine had).

[newtobricks]

I just ordered a megasquirt kit and am going to look at a wrecked volvo wagon to get all the turbo bits i think thats the way i will go for now seems to save cracking open the motor anyway for the time being. until i get my other car on the road then i will prob rebuild the motor anyway sort the head out then.

yep, just read all the posts by Barry and do the opposite :)


do you have to deal with smog where you live?

[newtobricks]

here in Australia where i live, as long as u keep your registration on your car payed u Dont have to get Anythin checked cause they Dont to regular car inspections so its not a problem unless u have to get it registered so its pretty easy. u just make sure u pay it haha.

The 16 valve in N/A UK spec was 155 bhp, and feels quite brisk. It will burn relatively low octane fuel and there are NO issues with 95 RON.

The pre-89 turbos wanted 98 RON, and if you convert to turbo this may well become an issue.

The 16 valve just putting a little Volvo turbo on (and making the manifolds) I am told you can expect 230 bhp without significant extra work, if your ECU is clever enough, which (almost) rules out the Motronic and makes the 2.4 preferable unless you are near an engine management guru. I am told that if you have a good 16v engine (B234) you can pretty well bolt (apart from manifolds) an LPT turbo onto it (using stock pistons and rods) and be significantly over 200bhp - but I suggest that if you do that you will want good petrol available.

THE issue with the 16vs is that if the belt breaks or comes off you WILL need the head rebuilt with new valves, and the tensioner is said to be hard to get right.

I've never understood what the fuss is about this.

Sure, if the timing belt fails, you get lots of bent valves and, if you're really unlucky, flat spots on the big end bearings (only ever seen this once on a very heavily worn engine). But this is the case with 99% of OHC engines in existence. Yes, it's very nice having a non- interference engine, but change the belt and tensioner/idler every 30,000 miles or so and there's no problem.

This isn't a go at you, Rog, but more an oportunity to take this issue to task.

Personally, my 16v turbo will have the belt replaced every 5000 miles or so and the tnesioner too, but then I don't intend to do much more than 1500-3000 a year with it and also intend to rev the nuts of it, cam profiles allowing.

About 8psi of boost 3inch system (no intercooler) megasquirt ecu+msd ignition and water injection on 98 ron pump fuel.

i am pretty sure i can do all the tuneing myself and i hope for about 150hp :)

[BB-Q]

Why no intercooler? It's very high on the $/power ratio, expecially if you use a generic Ebay bar and plate one.

Water injection is an uneeded band aid at those boost levels, especially compared to an intercooler.

Remember, detonation will kill a turbo engine pretty quickly.

[newtobricks]

true i just like to be stupid and diffrent. lol while i am ripping into her i should just fit an intercooler i actully have one for a skyline i should be not so lazy and fit it i just hate long inlet tracts.

[rogerthechorister]

Have you 2.2 or motronic?

With any (non LPT) turbo on the 2.3 engine you should better 182 bhp - that was stock B230ET

If you have 2.2, don't pfaff about, put a whole B234 in and bolt an LPT setup onto it (manifolds is the fun bit). Intercooler vital. Result, about 230 bhp. Run 97 or 98 Ron.

No need for gizmos.

Next, decent exhaust and Freds chips (maybe bigger injectors) - 300 bhp - but you are at or beyond the limits of 9mm rods, so might as well get forged rods and lower compression pistons.

its a b230E

You must live in SA......you'd probably get defected if they had a look in NSW.

Took this 600 dollar volvo for a drive to the city and back 400km return run so well.

Since buying it last week i have serviced fixed 2 light builbs welded exaust and a waterpump total cost 200 bucks.

Now it runs like a dream very slow! right now but i love it so easy to work on nice to drive has character.

no don't you dare.

no don't you dare.

heeeee

[adrianpike]

no don't you dare.

Well you're just so approachable and love to share your wisdom, I figured "why not"? :e-shrug:

[newtobricks]

i am going on week end to get all the gear off a turbo sedan same year as mine its manual so i will take the manual box clutch ect.

[Forg]

its a b230E
If it's a 1987 & it's a B230E, then it's something fairly unusual in Australia.
Just thought it might've been worth pointing that out, to save potential headaches down the track; 1987 cars sold new in Oz were B230F's (and I'm pretty sure they ran Bosch LH-Jetronic 2.2).

[newtobricks]

i just did some looking ariund and it does have jetronic i made a mistake but the motor is a b230E

but it was changed about 50 000km ago so maybe they replaced an b230F with a B230E motor

is that possible?

[Forg]

It is possible, they sold B230E's here in 240's during 1985 (and maybe early 740's ... not sure on that though). The motor could also have come from a car sold in another country.

I hear the manuals arnt that strong...... I'd look into that, cos your engine may take it, but if your engine aren't atached to your wheels, then its a long push if your in the bush :P it'd be like having a holden lol

:hitit: are you seriouse :P I'm in sa, the cops here are corupt as hell, they've defected my friends 760turbo twice already :P they defect people for having slightly fraid seetbelts, even not having your window squirter bottle full :P. let me tell you what were alowed to do here before its a defect :P
- no chainging intake or exhaust manifolds, lol for some reason they then sed that you can have extractors :wtf: I thaught that was a monifold
- no changing cams, but can mod to give no more than 5% though
- no changing heads, but can mod to give no more than 5% though
- no changing ecu's (unless you do proper expencive testing, but they still dont let most people)
- alowed intercoolers, but can't stick out too far
- no adding turbos, or changing for better ones (or even worse technicaly)
- lower your car by no more than 2 inches (cant be choped or heated)
- pod filter
- exhaust, but under certain DB, has to have cats still ect

now, *some* things they will alow to be changed with a $3000 engineers report :P (for each mod) and if your desprat, probbaly bribe about 3 different people at transsa and not get caught :rofl:

lol or just have a sleeper.... by definition, somethign that looks like a volvo :cool:

*edit, you cant even have your sound systom to loud :P

True but unlikly. Chances are, it is from a 240.
What are the dates stamped on the head and block?
