mattysupra

thanks for that Chris. Most of the above is already done. But you have answered the missing bits for me. thanks again.

Someone is having you all on. That my friends is a used tea bag that has been photo shopped. Skwint your eyes and look again and i promise you it looks just like a used tea bag.

does anyone else have any thing to add to this? Like engine damper etc? Thanks

I would like August time if im welcome in my R34 GTR. I dont think the Supra will be back on the road in time.

i take it you dont want to find as you have not put any details up or Reg etc ? Cant really blame you as im not sure i would want my car back if it was ever stolen. What a bugger also that you normally block it in with other cars but you never while going on holiday. Hope you dont have issues with the insurance mate.

It was proven that mobile phone can not cause this. It has been proven that wearing clothes containing Nylon cause thi due to static discharge. Also there is a easy fix to this issue. Its called a earth on the pump handle.

Yes mate, its half the power. But if you do the maths on what the engine is been asked to do a Drag Car is given a much easier life engine wise. Lets presume this Drag car does 60 runs in that season at what ?? 8 seconds for that BHP? well that is actually under 1 minute of track time. Thats not even 1 lap of most tracks around the U.k. So lets say i want to do 60 laps on Donington for instance at 1 minute per lap, that is the same as 3'600 drag runs in comparison if my maths are correct. (which i dought as im Dyslexic!) Add into this the fact that i will be running high temps for maybe 1 hour and no oil changes etc. The drag car in compassion will maybe see high temps for maybe 3 seconds each run? I would also guess it would see 3-4 fresh oil changes over the season? Also regarding the crank bearings. im confused on the stock v ACL. If a bearing lets go/wears then the crank is going to be scrap what ever happens! End of the day a bearing should not let go unless its starved of oil. This is why im double questioning the stock oil setup of a supra, i have run bearings before due to lack of oil. Again going back to my Skyline i run wide ACL bearings with a baffled sump and a Accusump to protect the bottom end. To me the difference is massive between a track car and a drag car with what you ask the engine to do.

I was using my supra to tow my real track monster there. With the option of using the supra for the rest of the track day if the other car failed LOL. (well its a skyline so it desting to blow up) on a serious note. I really hate towing mate. I said never again after a incident with my Skyline on trailer last year. Lucky for me there was no crash but came very close. From now on i will drive my track toys there and if they break i will get them recovered. O and a set of slicks fits in both the skyline and the supra so no worries there.

Sorry i missed that! Better be safe than sorry mate. Great thread.

Is this a Drag car or a Track car. Im not dough-ting that the 'quickest' car on here is stock parts, but running around a track puts a hell of a lot more strain on the engine than a car that gets run for 8-10 seconds down a strip and then cooled etc at the end of it. I do presume your talking Drag car mate? if it is a track car making loads of power you are about to save me a lot of money LOL.

Yes mate, im trying to reduce weight. But as i remove weight i seem to be putting it back in with cages, bigger coolers etc. Still im sure i will weigh in less than stock but not by much. Also to my disavantage is im keeping the car road legal to drive to the track and nip to the shops in.

Hi Jamesy, had a look at your spec. I see you dont mention pistons or rods tho? is your 742 bhp at the flywheel or the wheels? Also i see you have = Injector Clinic 2150cc Injectors ?????? is that each i take it? what does it drive like at slow speeds and tick over? O and to ask everyone else. What can sort of power can the stock fuel system supply? i see on PHR website it suggests 500 RWHP. What size are the stock injectors then?

thankyou for your replies So to conclude, uprate pistons rods bearings/bolts (arp / acl???) billet tenstioner (tilton ?? ) Oil pump is o.k using stock? What make cambelt? is stock o.k? Headgasket is o.k using stock? What about things like harmonic dampeners? Again skylines can suffer with harmonics damaging the oil pump. Are we sure the sump will be o.k on a track car? sorry for double checking but im paranoid after owning a skyline! Also what is the max you should bore the block. I think i can get away with some 86.5mm pistons but i may need 87mm. Is 87mm pushing it on a high power track car?

Yes i did wonder that as i think i seen he had a electric pump on the engine. But im guessing he is going back to manual pump as im not sure how else he can send teh belt over to the supercharger? as in picture here - http://www.mkivsupra.net/vbb/attachment.php?attachmentid=128475&d=1300312596 Im sure david will be along soon to fill us in. Ps, if there is a electric pump for sale im looking for one at the moment

Hi all. Been a while since i posted on here. Still i see a lot of old names still floating around. Anyway, my old supra has come out of hiding and i have decided i want to turn it into a track car. The car has a good spec around the outside of the engine but now im going to concentrate on the insides. So what do i need internally inside the engine? Im looking at making around 600-700 rwhp. Dont forget this will be a track car running slick tyres etc so will be under a lot more force than a road supra. One of my bores has damage so i will be boring the block and running over sized forged pistons. Do i need rods? what bearings? What head bolts? What head gasket? What cambelt? Do i need a better oil pump? Do i need sump baffles or a extended sump? Should i be changing other parts aswell? I have tried searching but cant really find any solid information. found a nice bent rod pic tho out of Jamiep's car (very impressive) ! Thanks for any advice.

some great work there mate. I started reading last night and skimmed over the last few pages today. one thing i have noticed and im not sure if it has been covered already ....... the belt driving the supercharger, where it goes around the water pump it will be turning the water pump the wrong way will it not ? Obviously this will cause you issues. Just thought i would point it out to you mate before you cook the engine.

may i ask please, what conversation figure do you use to get flywheel BHP. obviously the DYNO you was on reads at the wheels but for some reason always gets converted to flywheel. Do you all know what your true wheel bhp is?

do we know what 4wd the Russian car was using? im going to guess maybe skyline or judging by engine it may even be Nissan Patrol?

Yes mate, but im woried about fitting silencers in. After all i need the car to meet DB limits. Im thinking of raising the floor drivers side to allow for clearence of teh exhaust and get a couple of silencers in. Now if i use bucket seats this is not a issue as i will simple mount them lower. But if i decide on keeping stock trim look then teh seats will sit to high. I think the car is going to have to be turned into a proper track animal.

I think thats the easy bit mate ! From what i can see i think i can do this, but not sure what to do with the exhaust!

If your pistons are sticking im afraid grease will not help. You need to remove the pistons from the calipers and clean them up as they must be corroded etc. Use some 800 grit wet + dry on them untill they are looking like new. Then refit them and all will work as it used to. Ideally you should change the seals at the same time.

Yes mate, i have found this - But they are not using a 2JZ engine from what i can see in the pics.

Does the 4wd gear just drop in or do you have to modify? i presume you have to modify or every one would be doing this ? I think im set on using the skyline running gear as i believe it is the best 4wd running gear out there and is proven in the skylines. However if some one can make my job easier by saying xxx will fit etc it will make my day. I don't think i will hear that tho!

I have been thinking, basically i went on to buy a R34 GTR due to the fact that i was facing traction issues with my supra. Yes if you could get grip the Supra was a weapon on the road but a little rain and the supra was trying to kill me at ever corner. But now i have a R34 GTR there is no way the supra will touch it down the country lanes and i can use full throttle in the wet without issue. O and my R34 is making 590bhp @ the 4 wheels! Now i must say that i believe the Supra engine is a better engine than the skylines RB26, i also think teh supra is a better looking car all tho more common. . This points to the ultimate road car for me would be my supra running GTR running gear. or should i say a Supra powering all 4 wheels. So i get thinking! I have been measuring up both cars. I think that with a bit of chopping and using a skyline tunnel i can get the R34 GTR gearbox to fit along with transfer box. I also think i can machine the Rb26 sump to fit the 2JZ. Along with using the skyline sub frame and front suspension and steering rack, hubs etc i think i can make the supra 4wd! Has anyone done this before? Is there a better donor car to use?

This Event has been cancelled Just to let you know that this event has had to be cancelled due to lack of numbers. Was hoping that a couple of you guys would fill the spaces but with short notice i know that was asking a lot. However MGT Racing still want to run a DYNO day so i will let you all know of any future dates.
