Next stage?

Recommended Posts

depending on the dosh you want to put out

 

1) brakes + ss lines/fluid

2) boost controller

3) an afc

4) an egt gauge

 

imo... always safety first. yourself, then engine ... then comes the fun! err, reliability too should come somewhere in there .. ie plan each mod stage, then get used to it, then next ... all the while ensuring engine/drivetrain/suspension all doing ok.

 

maybe a bit pedantic but just my 2p

*Some decent gauges, so you can see whats happening...

*New fuel pump & FSE, 'cause the one you have is old and can't keep up with 1.2, let alone 1.3 bar...

*S-AFC to assist the above in making sure the fuelling's alright + a couple of hours at THOR to set it up...

*New intercooler, either a CW side mount or decent FMIC

*UK Brakes, you do need to be able to stop...

*RLTC, to assist you in avoiding armco's in future ;)

*Suspension, to ease the back pain!

*Neon removal kit ;)

*Single turbo, massive injectors, high lift cams, stand alone ecu, totally new and uprated fuel system, new pistons, new rods, head work..

*Bank loan/re-mortgage

 

None of those are in any particular order....

 

Can't wait to see it finnished :D

mmmmmmm....... to be honest, in hindsight I wish I'd

fitted the Walbro FIRST, before spending on the UK Brakes ! !

it would have (probably) saved me ~£1,400 in the long run ! !

[which, by coincidence is approx the cost of complete UK

brakes ? ! ? !:conf: ]

 

IF you're NOT gonna use the 1.3 Bar... AT ALL... then Brakes.

IF you ARE gonna use the 1.3......... FUEL PUMP ! ! ! ! :(

 

FatS. (well...LeanS in this particular case!)

You MUST know mate ? ? :conf:

 

the "I Melted My Pistons" story ? ?

 

NO ?

 

Oh well, let me begin:

 

" It twer a bryte bryte sonny dayy in deepest dingiest

Elvington, when.....................................

 

I melted 2 pistons.

I RECKON, most likely cause was running very lean.

It was 6,000-6,500 revs @ ~150/155 MILES per hour

(OFF road ! !:D ! !)

I think the Crappy-Jappy pump couldn't supply what the ECU

was tryin' to inject ?!

PLUS, VERY VERY hot day / fairly poor con' I/C etc etc.

 

(...................plus, I could/possibly/maybe have turned the boost

up to ~1.4/1.5......JUST POSSIBLY you understand....by ACCIDENT !

:music: )

 

TOO hot,

TOO lean,

BYE BYE Aluminium (and spark plug tips!)

 

NOW, you go to sleep like a good little soldier....

...and NO NIGHTMARES ! !:(

 

FatS.

If as Matt said your fuel pump is poor, that and a FSE will cost approx. £250 + Fitting. SAFC nice but not essential at that stage.

 

Then if you cant afford UK brakes, Chris Wilson does some superb pads which will transform J spec brakes, if a little noisey.

 

FMIC would be nice if you have the £'s.

im looking into getting a walbro pump at the moment and get fueling checked

its a worry running higher boost with stock fueling.

 

would it be good to link 2 jap spec fuel pumps?

 

also what is a FSE?

 

got some uk brakes and goodridge hoses in shed from not las billing but billing before. seems a shame sat there doing nothing. not sure about fitting just uk front brakes

will keep an eye on this thread.

FSE's a replacement Fuel Pressure Regulator that's adjustable..

 

AND, supposed to be quicker at responding to high demands...

 

ie. if Jap reg' is ~35psi then you set FSE to ~40

AND

it still rises quicker....

 

only about £100, BUT, it needs setting up with a Pressure Guage

 

(next-ish on me list.......)

thought it might have been a manual boost mod or something.

 

trying to work out what fueling mods you can do on jap supra`s

 

1. bigger fuel pump walbro seems to be highly rated

2. FPR/FSE

3. PHR Fuel Pressure Pulsation Dampener Bypass

4. bigger injectors

 

 

PHR Fuel Pressure Pulsation Dampener Bypass. A must-have for all BPU Supras, the PHR Bypass consists of a large #6 Stainless Steel Braided hose with metric fittings to route from the factory fuel filter to the rear of the factory fuel rail. Installation is a breeze: 1) remove the factory rubber fuel line at the fuel filter using a 17mm wrench, 2) install the supplied metric fitting into the fuel filter while reusing factory crush washers, 3) attach the straight end of the #6 line to the metric fitting, 4) remove the factory fuel line at the rear of the fuel rail using a 17mm wrench and move it aside, 5) install supplied metric fitting into fuel rail while reusing the factory crush washer, 6) attach the 90 degree end of the #6 line, 7) tighten all fittings and check for leaks, and you are done! This completely bypasses the OEM pulsation dampener unit, a severe restriction in the factory fuel system. Installation of this unit allows you to maximize the factory fuel system with less risk of a lean condition. A must have for any Supra! Can also be supplied with an inline adapter to mount any electronic fuel pressure gauge sensor. Price: $95.00, With Fuel Pressure Adapter: $120.00

FSE is just a FPR that rises and an higher rate than 1:1. I would leave the static at the same pressure as stock, but you can increas it if you are short on fuel.

 

The PHR Fuel Pulsation mod is just a bit of -6 braided hose.

Terry, Mark, Steve and Dude - loads of info and thanks; no Dude can't do tomorrow family thing - well no - my children want the day with dad without the car so ..... in the contract sumswheres when you inpregnate?

 

New fuel pump & FSE for £250 sold - who wants to sell 'em 2 me? PaulE, DUDE and GAZ I will be intouch for types and costs and advice as per usual!! lol.

 

S-AFC to assist the above in making sure the fuelling's alright + a couple of hours at THOR to set it up...

 

How much - is it worth it at 1.3bar?

 

And I'm also up for the Apexi EGT or the Autometer version Dude rattled on about today for half the cost...LOL

 

Mark - want those breaks man and will gladly bid Dude out; he's to busy blinging the entire world to worry about stopping!!!! Errr well how much and are you ????? willing to let them go?

 

So £250 + £280 Apexi, plus fitting of ??????£

 

Steve - good god, 1.2 from now on!!!!

Mid, Paul E was selling the fuel pumps and FSE's cheap.

 

SAFC, like I said not essential. It will just allow you to fine tune the fueling whilst on boost with the FSE ( the FSE will act EXACTLY like stock FPR whilst off boost). You might make a little more power with it.

 

Brakes, seriously, try CW's pads for a while, unless you find a cheap set of UK's, and the put CW's pads in them!.

A big help this evening Terry mate. OK. PaulE are about to barter on said items. Sounds like SAFC is a waste right now.

 

I am also looking for an exhaust gauge. I here CW is great at this. Anyone - Geeza forgot sorry - know how much to fit said item, I just need the guage right and CW would do the rest.

 

Also - Terry - is it worth getting my first CAT removed? Still in and backing off 1.32 bar, butting running 1.2 norm and .9 for work?

 

errr £cost to fit EGT and items required - I like this upgrade thing! FUN LOL
