Nissan 200SX Club - South Africa

See you soon then

Ok couldn't see the pipe that goes under cowling, makes sense now, thanks.

So here it is, just as I thought....it wouldn't just be a head skim and new head gasket...

DET like hell on cylinder 3, must be from the engines previous owner as when we were tuning it we were doing so with a knock box with no DET:




The gasket failure:



Some of the other cylinders also have DET and another section of the gasket was very close to giving up:





Don't have a clue how I am going to be able to pay for the rebuild....so if anyone has any ideas I'm all ears!

damn
sorry to hear man
what HG were you using?
all i can suggest is fresh import engine from mikes place in epping...
i hope you come right

I believe it's just a Nissan one, so not really designe dfo rth epower, and with the DET marks on the block, if it was replaced and the marks were left it was only a matter of time before it gave up.

I'm not going to get another second hand motor, this time I'm going to do a full rebuild so that I know exactly what is in my engine. Plus I might be getting a little temp skidder for now so that I can build it over time and properly.

Yo buddy, nice ride bru, hope u get the beast back on the road soon

Thanks bud, I also hope so!

This past Wednesday was the Wheels of Fury event and I was going to try just get the head a block skimmmed and a new head gasket fitted just so that I can go drift, but after pulling the block out and seeing some of the damage on the pistons I immediately determined that the engine was in need of more work.

So after much thought I gave the go ahead for the full rebuild, and thank goodness I did. After stripping the block we found a run main bearing, all pistons are pitted and damaged and the detonation damage all over:







And this is how the car stands now:


The rebuild is going to cost around R16K as the engine is going to be perfect! The head and custom headgasket are done. Just waiting for more funds then I'll do the rest step by step.

But not all is doom and gloom, got my hands on a V8 S13 that has recieved alot of bad reviews in the past and sat on Gumtree for sale for a long time as there were rumours going around about the chasis being skew, everyone warned me about this car. I personally knew this car and the driver, and after testing it was found that all it needed was a full alignment setup.

More details to follow in the new build thread for it but here is a sneak pic:

So this engine rebuild is taking a while as I do it in bits, as and when funds are available.

So far the head is done, the custom Redline 3mm indestructable headgasket is made, the custom pistons and rings have been purchased and the SR20DE throttle body has been purchased. I need to raise about another R10000.00 to finish it off including the new 900cc injectors, block engineering work, gaskets, bearings, setup of the head shims, oil pump, water pump, timing chain kit, consumables and a final map (I'm sure I'm missing some bits there).

The plan on the engine is to run a compression ratio of 8 or 7.8, run it on Avgas with the current turbo setup and 900cc injectors. We should be able to see 300kw out of it by the end.

In the meantime I have made up an a-frame for towing and had the car on show without the engine for some extra exposure at the Tekton car show in Wynburg on Monday night 30-04-2012.

(Excuse the front height, it's missing about 200kg's from it)

Another big change on the car that might happen is the GTR-D's are going and the fenders are going to be flared even more to fit in the following set of ROTA's in there:




Specs are as follows:
Front: ROTA MXR 18" 10J ET12 235 Flaken Tyres
Rear: ROTA MXR 18" 11J ET8 265 Falken Tyres

The only decision left to make is whether to go for the white centre with polished lip for a classy look or the flat black centre with gloss black lip to maintain the dark look of the car, thoughts?

Other plans for the car is to fit the rear lower arm polybushes from Driftworks, fit BC Coilovers and change the front bumper or fit a diffuser to the current one and clean it up (the body kit is still to be painted the same as the rest of the car).

I need this car going again....it's sad seeing the car sitting around not doing anything!

Why are you going to drop the compression that much, for the parts youll be fitting youd be much better off with the 8.5 atleast.

The lower the compression the more youll need to boost it to make power. We made 439whp on the Perfect power hub dyno with a T61 @ 1.4 bar boost on the stock Sr20det without any issues. (But the guys did a good job of tuning it)

As a safety and to allow me to run pump gas. The idea of dropping the compression ratio was that I was initially only going to run pump gas, it's only recently that I've taken a liking to Avgas The quality of Avgas also varies between different batches and is therefor safer to map the car for pump gas with a bit of a rich AFR to allow for the slightly leaner running Avgas.

The engine is being built to be safe and reliable with safety margins as I am not known for being soft with my engines when drifting.

The stock compression ratio is 8.5:1 and I was just starting to detonate on pump gas at 1 bar when we were tuning so we turned the boost down to 0.9 bar to be safe and adjusted the timing accordingly. This is all road tuned too for realistic conditions.

What fuel were you running for that power? I am also not interested in the slightest in running water meth or race fuel all the time.

I am also sticking with the GT2871R as I can't have more lag, but I may be changing the exhaust housing to a T25 one (.48) to reduce the lag even more provided we can get it to fit. We still need to look at this and see if it will work. Also looking at running 1.5 bar boost

Why dont you want to run water and meth?

Put simply, reliability. The whole car is being built around reliability. I'm not going to have my engines life or death dependant on one small pump that pumps the water meth.

I have stuck to using as much oem on this car as possible where it counts as nissan spent many hours of development on everything, why mess with that? Z32, standard ecu (nistune), knock sensor, two standard intercoolers in factory position, resized standard injectors, sr20de throttle body, standard cams, retaining vtc, hydraulic lifters with a properly shimmed head as per wsm, standard rods, etc...the list goes on. Taking nissans best, putting it together and fixing what won't work with twice the amount of power from factory.

I can see some logic in what you are doing.

I personally will not run that power without water and meth, Avgas is just as unreliable in octane levels (can see why your dropping the compression).

Water and Meth is very reliable, the pumps are made to last. Like all things, you just need to look after it.

But each to its own, I can respect your views about it.

If I had to go that route, I would run a race fuel mixture. I know of a few guys in the racing industry with race cars that run a race fuel mixture. More reliable than avgas.....

Any reason why you dont want to run race fuel?

Yeah I know but I just personally can't rely on one pump. If a fuel pump packs up the car stops running....it the water meth pump stops working or for some stupid reason you run out of the mixture...bye bye engine.

Race fuel just costs way too much. I wish I had the funds to run race fuel but I would have to run it 24/7 (as the car is stilll used on the road) and I just cant afford it. The route I am taking with big safety margins allows me to run with pump fuel on a daily basis at high power without much of a side effect, and allows me to run avgas for that little bit extra.

The engine is getting rebuilt anyway due to failure and needs new pistons so whilst I'm there I figured why not do it this way. We have done much thinking and talking about the setup with Redline and I think we are on to a winner. We like to do new things, try things so that people have alternatove routes to follow when we pull them off.
