well, sound system really, and fse gauge ect, but thinking bpt it?

**Posted:** Fri Jul 03, 2009 4:31 pm

probably an easier route bud. buy a half cut you'll pretty much have everything you need

injectors are in and i even stretched the wallet and got bailey dump valve for staggering £9 on ebay haha. turned fuel pressure down to 2.5 bar from 3 after installing new injectors. o2 gauge is constantly reading ratio of 11.5:1 aside from lifting foot off throttle it doesnt move?? any thoughts? standard injectors rated @ 3 bar is 161cc/min. mx5 injectors rate @ 3 bar 212cc/min. ive even turned them down to 2 bar. doesnt make any difference....yet thats less fuel than old ones that were turned up to 3 bar!!! right even i'm confused now.

old injectors back in.fuelling was all over the place. I expected ecuto throw a little wobbly but christ! managed to get apexi afc from japan for £20. so hopefully will be able to tune it up a little. anyone know the standing on side exit exhausts passing mot? easier route for me to take plus gotta be a bonus getting gasses out quicker

Dont take my word for gospel but if I remember right, as long as the tip doesnt protrude further than the skirt you should be ok (you will need a cat though for emissions) otherwise it should be ok I think? Anyone feel free to correct me here.

I used to have a renault r5, loads of fellow owners had side exits.

cheers mate.right the b*tch is going on.got one more weld to do tomorrow and i'll bolt it on.mot not til october so got few months of playtime at least

**Posted:** Mon Jul 13, 2009 11:09 pm

when ur mot expires pm, and i can do it for £40, would like to see ur car in acion

**Posted:** Tue Jul 14, 2009 2:35 pm

Mate, well done. I have just picked up on this thread and its great that someone has the imagination and skill to make there own conversion kit!

Garrett off a 9-3 wont boost till later but I bet it boosts all the way past redline.

Are you going to use a 5th injector with the piggyback and are you using a map sensor or just sticking with the MAF?

Also what boost you running on the standard internals? You staying under 6?

**Posted:** Tue Jul 14, 2009 7:06 pm

starts spooling @ 2000rpm in 3rd. gate's set at 7psi at the mo. got bigger injectors ready to go BACK in and am awaiting apexi safc from japan. hopefully will take it upto 10psi. from what i could find out. thats pretty much the maximum stock internals will take.still running on stock maf.it'll do the job.

anybody know why my ecu doesnt seem to follow any mazda pin layout? what I mean by this is I found 3 different ecu's that have 2 plugs. the first with 26pins the 2nd 22pins. according to these drawings the airflow sensor is in the same place....and mine isnt????? should be i think 5th pin from left on 1st plug. just an empty slot. I found mine. mines on bottom row nowhere near where it says it should be. my ecu says z5-b. anybody a guru when it comes to ecu's? doesnt bloody help when nothings following any drawings. how can it be working right if its all over the bloody shop....

**Posted:** Tue Jul 21, 2009 10:43 pm

Might be able to work out which type of ECU you have from your VIN number chap

**Posted:** Tue Jul 21, 2009 11:50 pm

Personally I have not understood half of what you've posted up, but just wanna poke me nose in and say fair fu**in shout for doing this and gettin it up and running (let alone even attempting it in the first place!)

**Posted:** Fri Jul 24, 2009 8:06 am

I dont understand alf that crap either.honestly.til this project id never lifted a bonnet.ever! if something fell off car id throw it at a mechanic.thats that.im biker.spent teen years tuning 2 strokes and ragging superbikes.my bike has been off the road for 2yrs.missing her now.so trying to get my thrills from this car lark.the lads go on about ball joints and track rods....i havent got clue what THEYRE on about.im used to a block engine in a bike frame or a blob of motor bolted to an altenator!

**Posted:** Fri Jul 24, 2009 8:15 am

Anybody can bolt turbo to their motor and it'll run.honestly.thats easy.it runs fine with stock everything.but as soon as you wanna drive like you normally do.it cries AHHHH YA B***ARD.WHAT YOU DO THAT FOR! The hard bit is getting fueling tuned so you can rag it. i havent finished this project but im getting ready for next.should be getting v6 in feb.top of list is twin turbo.gonna need miracle to get it all in.gonna give it a go.if that fails.go for easy supercharge

Ross/Weisco do ungraded internal parts for the Z5 engine, not got the link anymore but Mark T might have.

From memory, I think the kit costs over £500 but you can order seperate parts

Very, just very expensive too :

andy buddy. my vin number is JMZBA145201586236. Please tell you can give me a pin layout. mine just doesnt fit bloody anything. Its like a mixture of 4 different types. do you know of anyone whos tuned with apexi safc2?

**Posted:** Wed Mar 03, 2010 2:24 pm

Would be really interested in finding out the bhp after the turbo is added to see if it would be worth while trying. Price also has to be a factor

**Posted:** Fri Mar 05, 2010 12:29 am

More a torque gain then bhp. Cost was about £150, but then I did all the work myself. Do it bud. Learning curve at least. Damn fun if not extremely frustrating at times.

**Posted:** Wed Mar 24, 2010 3:14 am

well done evzee, hoping to do the same
just wondering where did u run the oil feed from/to???

**Posted:** Wed Mar 24, 2010 4:13 pm

take you existing oil pressure switch out. Its tucked right underneath your plenum chamber. b!stard to get at. stick in 1/8 t-piece in its place. thread your oil line onto t-piece then thread your oil switch back on - although your gonna want to get new one. You'll need oil pressure switch which has sender terminal for your gauge and switch terminal.

I was in a smack on sunday. incase they right my car off. all turbo gear off now.

miss it already. didn't realise how much poke I had since I've put it back to standard.

**Posted:** Wed Mar 24, 2010 10:14 pm

Damn dude, thats a real shame

Hats off to what must be the only sussessful known UK 1.5 turbo, hope it doesn't get written off, we've not had a chance to see it in the flesh yet and my apologies for not getting that pin layout for you, life has been a little hectic since I posted that
