What to Do ??? Turbo or 2.7???

[cliffybabe]

Guys

Im really confused, I want my cab to go quicker but im not sure what to do, turbo it or 2.7 it??

Whats better a 2.7 turbo or 2.5???

What do u guys think?? I really like the idea of a turbo noise witht he roof down but I like the grunt the 2.7 carry's likes oguz motor.

The thing that has inspired me is my bird has bought a vxr 2.0l turbo and i now want my bm to out run her.

I know i'd be talking to Ant either way i just wana get a feel or people's opions on what to do??

Or thye other long shot idea was to put a 3.5 M30 lump in her but i thought that maybe to heavy for a cab

Thanks
Neil

ikeep changing my mind on what i want to do with mine(after it goes on the road )

thought m52 2.8 after having an e36 328i sport for a short while. with the added benefit of a lighter engine(alloy block) but nikasil issues on early engines.

then went onto m54 3.0 but it turns out to be a sparkys nightmare.even brianmoooore has admitted temporary defeat on one of these (m54 but not 3.0).so ive kinda left that one alone

now im thinking of turbo m20 since i have a spare engine but to be honest i prefer the linear power you get with normally aspirated.

whichever way i go ive got at least around a year to make my mind up as its got to hit the road first.

never been too fussed about the m30 due to weight.hope this helps sort of.lol

tubby all the way....2.5 would be easier as theres obviously no 2.7 to put together (lowered compression) ..


mind you if thats your correct reg and you have early engine you probably need a cr drop for anything other than a lowish boost.

Mine is the later 2.5 lump, Would that be ok for the compression ratio?

What sor tof work is involed can u just bolt a turbo on, ie turn the log manifold upside etc??? Or does the engine have to juiced up ie re-built and specing up the lump???

What sort of power would u look at form a bog stnadard 2.5 with a decent turbo put on her wth MS??

What about a supercharger?

Neil, will take ya for a drive in mine next time we link mate! .. go turbo mate! if you have late low comp engine, you need nothing more than just the bits and management... mine is the log mani upside down, but will need to be re-ported to line up properly.... quick list is-
1.manifold to be re-ported
2.turbo
3.intercooler
4.management (megasquirt)
5.bigger injectors

Ant can do this for ya! im loving it mate, and the performance is amazing, you will however want more and more and more!! ... pop down if your close to Enfield 1 day.

I guess it comes down to how deep your pocket is! If you have a limited budget, then i'd go for the 2.7 as it could be done for reasonable money and if done properly, will last you for years, but if you have a nice wad, then go turbo. You wont stop smiling mate. On the other hand, cut corners on your turbo build and you wont stop crying. I've never agreed with the Champaign dinking with Lemonade pocket philosophy. In other words, simply do what your pocket allows you to do, but properly

Totally agreed Ben No sense chasing lots of HP with an empty wallet, best you'll achieve is a load of compromises

O/T you find a copy of PPC in the end ??

[Turbo-Brown]

Including an engine rebuild, uprated brakes, turbos, management, throttle bodies etc. etc. I did my Twin Turbo conversion for about £4500.

If you can do the majority of the mechanical work yourself and do it competently you can do a bang up job for not too much of the folding

EDIT> Should add that I probably didn't do a bang up job, but it seems to be hanging together!

[bootyman]

Yeah thanks. I liked the bit about my engine bay being nearly as tidy as PPC's own Toby

Mite get my Noz tapped in so it makes real 500bhp and not show figures

[Ant]

Can we get a vid of the beast on the rollers ?? the tyre roar must be rather on its own

[bootyman]

I will take my cam corder next time. I didn't know what to expect last time round cause it was my 1st time going to a RR andthe engine was also fresh and it was meant to be a base map, hence the standard injectors. Car just about fit on the roller! lol, but it was putting out over 200bhp and less than half throttle, with no noz and the noise was defening. It's also not a good idea to stand there watching the engine that you spent a years wage on screaming like a bitch

I nearly told Dave at one stage to take it easy At least i know what's involved for next time now.

As far as the question in hand goes, i've had a 2.7 that layed 210bhp on the roller and they reckoned it was loosing around 30bhp due to throttle bodies not being right and ristricted breathing, so that was a potential 240bhp, and ok, the turbo cost much more than that engine, but there is no comparison as far as fun factor goes. I let a couple of my mates take my car round the block and both couldnt stop grinning and both are considering going the forced induction route now. One took the car out 1st, but he came back after only 2 minutes and i knew he was so scared he didnt put his foot down, so i told him to take it out again and give it a little push. He was gone for over half hour whilst i sat outside his house worrying about receiving a call to say my car was in pieces. All of a sudden his usual bollocking me for having my engine done has turned into "How much was your engine again?, with a big grin"

[FlappySocks]

Why aren't superchargers more popular?

[bootyman]

A lot harder to do as it's still in the early stages of development for the E30, and wont give you as much power as a turbo would!!

[cliffybabe]

So its gonna be a turbo then

[cliffybabe]

Ok so regards to my engine I have a 325 i think it has a 8855 head, i think form when me and folwer done the inlet, is this lump any good or do i need a different 1???

[Demlotcrew]

What about getting a S14 and turbo that?

No other engine+ Turbo will even come close.

If you have the later facelift engine with the 8.8-1 C/R it is the ideal M20 to have/use.

You can use the earlier lump as Alex has and still get good results but with a lower limit on power.

Just need to buy all the other parts now...

I'd make a list in the wanted section and see who has what laying about, there was a BBR manifold in someones garage not so long ago.

HTH, Mark.

Guys

Im really confused, I want my cab to go quicker but im not sure what to do, turbo it or 2.7 it??

Whats better a 2.7 turbo or 2.5???

What do u guys think?? I really like the idea of a turbo noise witht he roof down but I like the grunt the 2.7 carry's likes oguz motor.

The thing that has inspired me is my bird has bought a vxr 2.0l turbo and i now want my bm to out run her.

I know i'd be talking to Ant either way i just wana get a feel or people's opions on what to do??

Or thye other long shot idea was to put a 3.5 M30 lump in her but i thought that maybe to heavy for a cab

Thanks
Neil
