well it appears the bottom end may have gone now, just got it on the ramp and its knocking badly and the oil looks like it has fine glitter in it.
the one bit id hoped had been built properly obviously hadnt, it still has good oil pressure but theres a noise.
im at my all time lowest with it now, it seems it may be the best obtion to just break it at the moment, really dont know what to do but i do know its testing my patience.
this car has fought me all the way i think its just a looseing battle

 

TBH, there is a good chance it's due to the flywheel coming loose and the crank damper coming loose.
Loss of balance or damping due to these can shit the big ends.

Ive even seen engines that have had ultralight flywheels shit the big ends within a few hundred miles of fitting them.

 

well thats a shitter.
i know how it feels to have things always go wrong.
ive had the 5 6 years and its never been at its full potential for 1 reason or another.

just put it to one side for now and play in the gtr for a bit.
come back to the supra a bit later on.

 

i guess it could of done, ddint drive it much though cruised to tuner about 90 miles and saw oil leak so got aa lift home. i guess i just gotta get the lump out and see whats what in there.

 

can you just pull the sump off and take a look ?

 

yep at least i aint carless, i gotta get stuck in though mate make or break so to speak, trouble is i will probably start cutting the rape tommorrow so time is gonna be short for a while.

 

i cant get it off without either lifting the engine or dropping the frame, the ammount of glitter there is in the oil and the noise its gonna be terminal for sure, il just have to get stuck in.

the full brian crower 3.4 kit is Ł5000 all in uk supplied, i have a brand new fully worked head on the shelf ready to go, if i rebuild it i will be going for 1000 hp in mind.

 

Rebuild it to 1000bhp then let me have a go.

 

Not good you have put a lot of time into this car and not even really use it yet! I bet your gutted! Still every thing can be fixed just money and time

 

I no everyone says these supras do 900+hp with no trouble and they are reliable etc etc!!

I have worked alongside afr tunning for some time and know all the lads well and believe me when these supras are up there in the power theyre always falling apart!!

Jons (supra dude) has been apart more times that i no and it always the big ends going..he is on his 5th bottom end and thats just a drag car..

The 750 hp mark is about the safest limit imo and in thiers..

Hope you get it all sorted mate..good luck



cheers danny

 

You can never have too much power. You can only have too little grip.

 

What about Jamie P's? He's running nigh-on 1300bhp, rarely hear about him ever having problems, and that get's used a lot!


Gutted to hear this though pal, what would it be worth in bits? Would it be worth breaking it and shoving it into the GTR? I know it's kind of a step back to what you had, but it's an option!

 

My experiance with a Supra a few years ago 872hp at the hubs on a 3.4hks engine kept spining Con rod bearings where the 3lt never went wrong.
This was only one car and not a generalisation on them.

seriously gutted for you mate, you must be over 30k all in now? what would you get for it broken for parts as it is?

when you first posted about getting the car, i wasnt sure it was a good move because of TDI

 

Never nice but you know your shit and I'm sure you can sort it if needs be.
Any high power motor will have issues at some point no matter what anyone says.

 

Thats the thing..you never do hear about all the problems..

What do you think they drive them around like a normal road car doing 12k a year??lol

I see guys that work on them all day everyday and the only ones that seem to stay together are the ones under the 750 hp mark..

The quarter mile cars come and get the bottom end re built every season

And johns own car has had like i said 5 bottom end in it that i know of from the 3.0 to the 3.4 and theyve seen 1177 hp but it just falls apart..




cheers danny

 

well i havnt had time to look at the car at all yet, ive just got in i started harvest today cutting the oilseed rape.

i have spoke to owen developments today about checking the turbo as there is a small ammount of end float on the t51r, so that will be as new again and all set now it has the proper oil pressure.

ive also spoke to garage whifbitz and he supplies crower complete 3.4 bottom ends and will build me a bottom end if needs be, but i just gotta get it apart and get the crank and rods inspected just incase they are reusable, whatever happens if it gets rebuilt or a new engine i am going to have the crank balanced with the clutch and front pulley on there if possible so it doesnt happen again.

im sure the loose front pulley has been the cause of the clutch issues, and the strange idle issue i was having i would susspect is where the engine was just tightening up somewhere before the failure. it is an awesome car and i dont see it being realistically replaceable, but even with a knackered engine theres still lots to sell, id guess i could still return Ł20+k in parts, but if i do that i just gotta start again as i am going to have a 1000 hp car one way or the other .............

 

that is interesting mark, did the crank take a grind ok ?

 

I dont know if it was reground or new.

lol id like a go first

i am gutted but ive seen pod and done 4 or 5 runs, some road work aswell saw of an r1 right past its top speed, i admit ive had nowhere near as much life out of it as id hoped for but ive had some.

im not admiting defeat yet, the only thing swaying me is if 2jzs arent any more reliable than an rb26 then a 1000 hp gtr might be on the cards as i do love the 4x4, if i had the supra power in a gtr it would be epic 0 - 100 mph, especially on a sequential box that i can get for Ł6500.

i think around Ł20k+ but its all a guess, some good money there though the shell has to worth quit a bit just the kit and body mods cost over Ł7k ! and then it had a full respray ontop of that !

i paid my money and took my chance, living as dream is never cheap real tears lol

i may build it myself, i just wana get my head in there and take a look then go from there. theres lots of brank repair people ive seen online so gotta be worth a go, after what some comments have said here i may just go 3.0 if the whole bottom end is junk.

 

jamie p runs a stock crank still and is still on the cars original one !

 

Isnt his a stroker now ? He put a new engine in it a year or so ago.

 

bad luck dude. as i've said previously - you're doing lots of fixing but will be epic when done!!

 

Gutted probably doesn't come close to how your feeling right now. I'm sure it will be worth it in the end but its never going to be a cheap build.

I'll have to ask my mate what they are using as their expecting 2000hp + from one, I don't believe its a stroker but I might be wrong about that.

 

your not having much luck mate,but i think most of us on here have had a car a sometime or another thats given us grief ,im sure you will get it sorted,CHIN UP

 

couple of lads in Ilford have 8-900bhp motors in mk4`s and E30`s

lots of boost and years without problems, just bad luck matey

any model/engine can have bad luck, fuck it, crack on lad

 

chin up, anything worth having is worth working for.
shitter none the less and i think i have it bad with a few k in a zetec turbo setup

 

Gutted for you mate, but Im sure you will turn it around and get back out there

 

nope 3 litre and hes still on the cars original crank used in last rebuild !

hopefully, it hasnt lived up to my expectations yet ....

im looking at this now potentially


http://whifbitzperformancetuning.co....z-p-15063.html

and just give him my new big port head, my 272 cams, block, oil pump, water pump and sump and away we go again. i can then sell the salvageable out of my bottom end, even 6 pistons and 5 rods will fetch some ŁŁŁ

im trying to stick at it fella, the more i look at parts the more i want to get stuck in and get it repaired.

i dont think its bad luck, i think its a numpty not tightening up the front pulley thats caused all my issues that have now ruined a Ł15000 motor potentially ! owen developments are gonna check the turbo out aswell, its ok hasnt failed and is working fine but there is some shaft float im not happy with, they seemed hopefully being as its not failed it may be repairable or at least a new core from a gt4202r with my wheels and shaft should still then be a genuine hks t51r spl, again the turbo is just from a wrongly set up oil feed to the turbo !

but onwards and upwards is the plan and at least try and get past 800 hub hp and also have a 500 hp boost setting for some civilised driving so i need to change the wastegate springs from 1.7 bar.

 

I wouldnt suggest that.
Its a good idea in theory but if the front pulley/flywheel/clutch ever need to comr off get changed then the assembly would no longer be balanced.
Your better off getting each part balanced individually.

 

that's the spirit, onwards and upwards, i've got a smoking turbo, so thinking gtx now, spend it on the right parts is the moto.

 

well the engine is out, on my engine stand, cams out just gotta unbolt the head now.
il be honest though im looseing the spirit the more i strip it i dont think ive got a rebuild for it in me atm.

seen an r33 gtr 750 hp im tempted by aswell..........

 

well ive got it all stripped piston skirts have marks, crank is gone, at least 2 rods have failed, bores look crap, its all hks just looks oil starved, i guess that would explain needing no oil restrictor. i have genuinely lost all interest tbh im beyond gutted, to rebuild as a 3 litre is not something im prepared to do its supposed to be what it is a top end hks car, for that reason and the fact i want to smash the thing to pieces im breaking it for parts. il be honest i feel quite sick at the moment !
im in mid harvest been at work since 630 this morning, had quite a bit of interest in parts already so hopefully i can recoup a good bit of ŁŁŁŁ and start again with something else.

 

Sorry to hear that mate :-(

 

its cost me Ł30k so far and ive done 2500 miles in it !
totally gutted

 

Sorry to hear about this mate and i hope you have more luck with whatever you decide do next

 

Proper shit news!
Hope you can recoup some cash from it.

 

Oh dear, sorry to hear that mate

 

Thats a real shame.
Just be sure its 100% the right move before you start stripping/selling parts!

 

it is mate, its either sell it now or i will smash it up in my temper, ive had enough of it, not enjoyed the car enough as it is so gotta go.
