more horsepower needed

[spook]

on my 325, im clueless when it comes to engines, my engines bog standard,so can you advise me on some basic upgrades that would give me swifter acceleration , im looking to spend around 200 quid
thanks spook

[march109]

big bore throttle body? cold air induction kit? should be a little over Ԛ£200

[maxfield]

zone chip

[march109]

Which would give the better gain for Ԛ£200 though? Anyone ever RR these to compare?

[d6dph]

Chip and bbtb is a damn good start. optimise what you have, then go seeking for more ponies!

[Ant]

Ԛ£200 to spend.....

1, Fit NGK ( only !! ) Spark plugs for a chromie car( up to 86 in catalogue)
2, Service car fully, oil, fuel and air filters, retain std airbox(for now)
3, Zone chip( I got your PM today BTW dude )
4, Zone BBTB.

OK, with the service items its over the target Ԛ£Ã”šÃ‚£ but its close enough, and a worthwhile investment dude

[d6dph]

Whats the difference with the late/early plugs Ant? Im running late ones in the turd, just curious if i should change to the early type?

[Ant]

Temp range is about all Dave, but NGK normal V grooved have done 10K on the turbo without any issues at all

NGK NGK NGK, no Bosch or chumpion wrongness, and save your Ԛ£Ã”šÃ‚£ on the iridium/whatever specials, leave those to the ricer market.

[d6dph]

We stock NGK hence i use them, cheap as chips to me fella.

I had iridium in my nissan as they cost me Ԛ£4.50 ea and have a supposed 60k life!

[JAFF]

hi i have a 320i h reg i have done a service apart from and oil change and have a K&N im looking at a zone chip but wot else can i do ,wot is BBTB ?and how difficult is it to get a bigger throtle body and fit i have already got the NGK plugs as well

[spook]

i also have a full dtm scorpion exhaust system on the car, ive read about the throttle body on the forum, which car do i source the t body from, is the chip kinda like plug and play, and whats a bbtb, and m y cars an 89 model are these plugs still ok, thanks for all of your advice, keep it coming,spook

[d6dph]

bbtb = big bore throttle body, chips available from the zoneshop or Ant, bbtb also from zone shop

[spook]

thanks, i can see some more dosh flying out of my wallet

[fuzzy]

thats gauranteed mate,and itll be flying out forever more in the never ending quest for power

[march109]

What the max sort of BHP that can be had out of a 2.5i?? Be interested to know N/A and Turbo figures.

[Turbo-Brown]

Bit of an unanswerable question really, possible power depends on how much skill and money's thrown at them.

Gather that 400bhp's easily achievable with the right turbo and management, think you'd struggle to top 200bhp running N/A to be honest though.

[march109]

pretty much what I thought turbo wise, a little surprised on the N/A front though, thought it would be nearer 230 tops, but would have thought 200 was pretty easily attanable with a decent rebuild and some tasty mods.

I know its a pretty hit or miss question just wondering based on what others have acheived.

Surprised the turbo could give a 100%+ increase though even on insane boost.

[maxfield]

You could build a 2.5 to 2.7 then possbly 230. Player6 is 2.8 and is pushing 260hp with alot of money planted init.
I think M20s take well to F/I

[Turbo-Brown]

200bhp from an N/A M20 is still 80bhp/litre which would be pretty respectable for a 2v engine!

The later M20s are low compression and can easily handle more than 1bar of boost, you should see a 100% power hike at a little less than 1bar. I got a 58% hike from just under 1/2 a bar

[Morat]

argh, I bought bosch for my facelift 325i. I guess thats what you get for going into Halfrauds before consulting the zone

[d6dph]

Thats just what you get for going to halfrauds in general

Im going to change my plugs today as it was popping and banging like a bitch last night. Will put the early ones in this time.

[he30]

Let me know what you decide on, i'd like in the regionof 200 brake,
cheers he30

[DRIFTBOY]

How about taking some weight out?

That way you get better acceleration, better brakes, better cornering and better fuel consumption!

Get rid of all unecessary gizmos and toys, soundproofing, junk you carry around, mudflaps, rear headrests etc. - whatever else you can do without.

Best of all - it doesn't cost a penny!

to get 200
youll be needing either a btb 6 branch or good cam

also big bore tb and a decent airfilter itg etc

this and good servicing should get you near 200

best bet is build a 27 tho
im about to do one for my car
should easily get over 200 with shedloads of torques

exhaust AND cam,200 isnt a dead cert .....youd be lucky to start off with 160-170 ,never mind the quoted new figure of 171.i bet if most of the stock b25s went onto rr -quite a lot of people would be dissappointed.

save up for a torque multiplier...lol,

[he30]

I like the sound of that daz mate but what sort of a beating is my wallet going to take for a 2.7 conversion, will i have to tell porkys to the missus again?
I hear your up for a trip to germany next year? i was contemplating it with a guy i work with (owns a new focus st) would be fun to see if we can get a few old e30's to spank him ha.

[chu346]

What's the model no. of the early NGK's?

[snoops]

NGK BPR6ES

[Morat]

boost it, you know it makes sense!
MS it first, save cash through better fuel consumption and put it in the cookie jar marked "Turbo Conversion"
