Sounds very promising, are we looking at a dyno run once its ran in?

what kind of money would/does something like this cost?

i am thinking about doing it to my cab (2.5 to 2.7)

"For those doing 2.7's properly"

(sorry everyone if this is too offensive!) but Sal, stop talking down your nose to people. It's tiring now.

I find that downright f*cking insulting.

I'd rather save myself Ԛ£3k and learn about what the hell is being done to my car, rather than let this garage do it.

As it happens, just picked up my donor car this morning, can't f*ckin wait to be quite honest pal.

BUT I'd also like to say, well done Quasar for going ahead and doing the conversion! Too much hot air round this place regarding this conversion.

OK guys - calm it down a bit!



Thanks sal for all the help so far

Jimbob - i hope it goes well for you - the engine worked out quite cheap for me - around 2k all in as i sourced a lot of parts second hand - inc. pistons, cam etc etc

The reason i got bexleys to make it was cause after working out costs for parts etc, i decided it would be better just paying someone to make it.

Also - as you say Jimbob, there was too much hot air with regards to this conversion that i didnt know which way to turn. The 320i head suggestions came out after i had already bought all parts.

Anyway - cant wait to get the chip and manifold on there - or to connect the kickdown switch back on it!

Good luck with ur conversion too.

Mail me if you think i can help in anyway!

Q

p.s. I have an early engine for sale if anyone needs it!

Just out of interest, when you say a big difference is this referring to the performance once the auto is moving or does the initial take off 0-60 massively improve too. I ask as I am quite happy with the overall performance of my 2.5 auto but just a little dissapointed with the automatics initial take off.
Cheers,
Andy.

I've been a 2.7 Auto driver for some 5 years. I think the extra torque really shows up on an auto. Before the conversion, there always seemed to be a delay with getting the power down on to the road, mostly at take off but all through the range really. The engine responded quickly with an impressive roar but not much happened! This is due to the torque converter soaking up the power and a fairly high gear and diff ratios.
After the conversion, the car is fantastic from standstill with very smooth power delivery and traction although I can still induce wheelspin if desired. Once rolling and with manual shifting and holding of the gears to match the power curven then it's a very fast and fun car. You can still enjoy the extra power even if you leave it in 'Drive'.
There is still a delay, however, as there will always be. I've had a MAF conversion done which has improved the throttle response which has reduced the delay to almost imperceptable levels.
I have never done an official 0-60 (which I must do). Not many beat me away from the lights though and of course you don't have to change into 3rd until you're doing 80!

OOOooooo - MAF -

So whats better - MAF or MBE which no one seems to be able to map properly??

I have a lambda sensor if that helps!

Also, Monsport, have you had your car rolling roaded - what output are you getting?

What spec is ur 2.7 and what else have you had done to it?

Finally, what sort of MPG are you getting?

Q

I really doubt that you will get close to 200bhp with just the block Sal, look at Karans car.

Yes if it has been stroked it will give more torque but it wont rev and it wont be progressive.

Andrew

240bhp on a auto box with no cam just the block MAF and Remap.

Edit: Plus gas flowed head and manifold with larger throttle Body.

Power at the flywheel after 5 hours on the dyno (very, very hot) was 237.6 and 213 ft lb torque.

Don't like posting figs usually as it usually starts a debate about autoboxes and dynos.
Quite happy with the MAF now. I don't seem to have the warm-up problems others experienced. Autos are difficult to map lower down the rev range but Bexley seem to have sorted it. That's not to say I wouldn't like it tweaked a bit more.
Average mpg about 27-28. 14 on track, 32 on a run.
I would like to put it back on the rollers now that the gearbox is working properly!
Andrew seems to have detailed my spec above. There's a little bit more going on around the pistons and compression tho!
Forgot to mention that mine was developed from a 2.3, so it was rebored.

Sounds like there's gonna be an army of 2.7's roaming the streets!

Just out of interest, what cam will you be using Quasar?

Well so far, the 2.7's I know for this year so far are:
Quaser (completed), myself, Templ8e30, tbmw.
And we haven't even made it out of January yet.
Do you know what cam Quaser is using?

Original Alpina cam by Schrick - 268/268 profile

Going for a standard cam for the time being, the power and torque increase from my 318iS is enough for me at the mo.

I currently don't have the Ԛ£Ã”šÃ‚£, but it's definately a planned upgrade - so if you could look for me that would be excellent. This and a 6-branch would probably the first major upgrades on the list, probably early summertime. I had so many problems with my iS that it would be a welcomed change to driving a van about, even if it's using it's full potential.

Thought I'd better set the record straight as far as 'slaughtering M3s' goes. I can give them a good run for their money down the straight and yes I've beaten a few but they'll always win on handling! An E30 M3 is very difficult to beat on track - that's what they're designed for. Unless of course you've got a stripped out racer. Wouldn't like to live with an M3 for everyday driving tho.

Monsport, nice reply thanks.
I have always wondered if that .2 litre made a difference. It is something i will now deffo consider and pester you about in the future, thanks again. At the mo a house renovation is gonna take all the cash.
When you say the 0-60 is improved greatly and not much takes you from the lights it sounds pretty impressive. A bloody manual escort si whopped the auto last year till around 70mph.
Andy.

Hi Lads, nice 2.7 topic, mine should be ready to go in by the end of feb, just waiting on some ARP con rod bolts and then its ready, any good tips on running it in, as ive heard you can ruin all the hard work done by running it in wrong, also as i run an MBE do i get it remaped after ive run it in, or is it a case of remapping it before and after. cheers lads

Have you ever been in a 2.7 and experienced this ?

I have heard people say this on a number of occasions, and it's just not true. My old 2.7 (now Karan's 2.7) revs just as well as any 2.5 - probably better with the MAF fitted.

Ian.

Ian im talking about the home made 2.7s not karans which has custom made lightened components.
I have experienced this, for me its like the difference between a 320i and a 325i. I feel like the 320i is smoother and revs better.

Edit: I have driven Karans Car.

Dale, where are you getting the work done? is it the guy who did your remap?

Ahh, didn't realise it was you

As for Karan's engine having lighter components, not sure where that came from. Karan's engine is the same as any other 2.7 using ETA crank and rods. The only slight unknown is the pistons. Les never did tell me what he uses, but I'm pretty sure there's nothing particularly light about them.

Ian.

Before I put my 2.8 together and fitted it into the car, people told me it would be torquey but wouldn't rev well, that's far from the truth, it soon shoots up through the revs with no problems at all.

Dale, where are you getting the work done? is it the guy who did your remap?

Hi Jim, no its not the same guy that done my remap, thou i will be taking it back to him to remap afterwards, i got lucky, this guy that i took all my bits to his machine shop to have done is also an engine rebuilder, i was going to do it myself, but after talking with this guy for a month he could soon tell that i know nothing so i think he took pitty on me and offered to rebuild it for Ԛ£250, , sounds a bargin and i hope it is, thou the proof will be in the driving afterwards, but he does seem to know his stuff, so finger crossed, keep you posted. cheers
