My Major Project PrtII - Single turbo Conversion

[leeroy_25]

Thanks guy\'s,

MaLicE - That position I put in is for the stock probe that used to fit in the CAT?? So it\'s in the same place it used to be roughly.. Maybe I didn\'t need to put it back in at all without the CAT there? I am not too sure of it\'s exact roll when the CAT is in??

Certainly appreciate some more feedback/info on that..
To be honest I don\'t have that much equipment.. I have just invested wisely on specific stuff to get the job done and have some good contacts for stuff I cannot do myself like any machine work. That being said I machined the fuel rail myself! Which I am lucky to have use of a manual mill and lathe at work.

Cheers for the positive words.

oh i thought you had an aftermarket exhaust gas temp gauge...

as far as i know that stock probe is just to warn you if the cat gets too hot... as you dont have a cat i wouldnt of bothered lol!

[leeroy_25]

Hey.. I thought it was some kind of temp wanring sensor for the CAT but I wasn\'t sure which way it worked!! Anyway.. It\'s in there now!

Will try and post some more stuff soon.. Got a busy weekend away!

[leeroy_25]

Okay.. Time for a little more write-up.. Last couple of weeks and been hectic!
There were only a few more bits to make for the car before I could get is all back together.

I needed to hook up the new fuel pump..
I removed the stock pump assemly and offered up the new pump to it.. figured I could do a bit of cut and shut on the pipe work and use some jubilee clips to hold it all in place.



Initially I set the new pump up with a modified stock filter sock..



Later I found this would fold over in the bottom of the tank and restrict flow so I got a walbro one and modified that to fit instead:



With that done it was all fitted back up.

I then made a little pipe and flange for mounting my dump valve onto my tust pipework:



I sent this off for welding up as I can\'t yet weld ally!

That was it.. Ready for final fit up! This went pretty straight forward at this point.




Ready to roll!

Okay Guys I am going to wrap this thread up for now..
What are you all waiting to see is how she performed on the dyno!
Well here are a few pics and vids for you.







The sound quality on the vids does not do it justice the turbo has a crazy whistle and when the wastegate lets rip.. Holy crap! I nearly shat myself first time it got opened up on the rollers!





Well as you can see it made 304rwhp.
I expect you are all thinking that\'s disappointing!? Well I was a little but the reason is that was only running at 0.8bar wastegate pressure and we could not go any higher as the ignition was starting to break up at the top end! So it was a bit of a shame but it has a lot more grunt that when it was stock so I plan to drive it like that for a while and in the meantime keep my eye out for an ignition pack.
Geff said it pulled well and the turbo preformed very well.. His guess was it should comfortably make 360rwhp which was my initial aim. Hey no one told me I needed an ignition booster! All good though.

Turbo wise it is very driveable.. On stock ports I was expecting it to be too laggy for my liking but it start spooling up around 2000rpm and hits full boost before 3500rpm. So I wouldn\'t say that was too shabby..

Well hope you guys have liked the thread.

Until next time!

great project car looks awesome i love those wheels

[m1tch]

Wow thats amazing! It really is very good work there yeah you do need an ignition upgrade lol im getting a custom one made, perhaps you could relocate the battery into the boot and then put an MSD where the battery was?

That turbo does sound rather good at spooling at lower RPM, what boost controller is that?

Just noticed on the IC to TB run, the clips holding the silicone connector are rather close to the alternator pulley!

But seriously, well done, it looks and sounds awesome

What boost are you going to run it to? Well more to the point, what can the injectors manage? lol Im going to be running my T88 on 1.2 bar or so but only briefly

[leeroy_25]

Thanks guy\'s the wheels I think would be classed as Marmite wheels! I love them on this particular car but hated them when I first saw them on something else! LOL!

Mitch.. Don\'t worry about the pipe clips.. They look closer than they are! Loads of room.
I am running off wastegate spring pressure at the mo but have got an early HKS EVC boost controller.. EVC IV I think. On the 850 injectors Geff reckons it will stuggle much past 1.0bar but that is the most I want to run anyway.. There is no point in adding extra strain to the engine as it will only break!

I had looked into MSD units and HKS Twin power but as you point out they seem to take up a lot of room so without moving the battery where the hell do you fit one?! I would be interested to know about your custom one as it would be in keeping with the rest of my project! I like to find alternative/cheaper ways to do things instead of going and paying top dollar for a name. I have looked at some generic amplifiers but I have to say electronics is my weak point so I am not certain what I need or how to wire it up. I was wondering if you could run an amp off another car that has a better stock one? And use that cars coils if required? Please tell me more!

There is a link to that drag racing FD, it has 2 huge MSD amplifers mounted in the passenger footwell lol

The FC coils are awesome, unfortunatly they are connected to 80\'s technology, so I am getting a custom setup that uses the OEM coils, just with better electronics

[turbotoaster]

hey mitch, when you sort out which ones you need could you let me know, im gonna need some beefy igntion system for mine and i have a feeling that the twinpower might not keep up for what i want.

I like the look of the MSD stuff as ive seen them on a few big power ones in USA but i dont know what i would need to order

[leeroy_25]

Mitch keep me posted with you ignition set-up. I have some spare coils which I think might be FC ones in the shed! Is there an benefit just putting FC coils with an FD ignition module? Would it get me any more power for the time being?

[m1tch]

I seem to remember that the FC coils were beefier, at the moment I am running stock coils but uprated HT leads, are you running upgraded leads on yours?

[rbs14a]

this would have been ideal with fd coils, sold now and very hard to get hold of but you\'d want something similar

[leeroy_25]

That does look interesting .. Expensive by comparisoin to an HKS unit though?

I think my leads are uprated.. I am not 100% sure though. They are red and a lot thicker than the ones on my spare motor which definately look stock!

Cheers

buy cheap, buy twice :yes
