i couldnt imagine a stock car like mine having an engine go bang without any mods

sure general maintenance will be required but after all, it is an old car

then again

you would expect a rb26 to be a tough motor

hence maybe i will take out the boost restrictor

but i should probs do an exhaust for this

It is tough but detonation will kill any motor

Give it the right conditions (shit fuel, clogged injectors, 18 year old fuel pump, 40 degree + days) and youre tempting fate

yeah the compression is pretty low, should be up to 160psi, and 120 is the low acceptable limit in the workshop manual.

but that assumes it was all done correctly:

engine warm

all plugs out

throttle open

good battery charge

and that your gauge is accurate.

generally, as long as the readings are fairly even (and those ones are) then the actual readings are less important.

Im with Duncan, compression numbers generally dont matter so long as they are all close. And they are, so i think its safe to assume your ok.

Its the same with dynos. Peak power doesnt mean a great deal as it varies from dyno to dyno. I tend to try stick to the one dyno and go for gains rather than peak.

For example, my old Integra Type R made 136fwkw with a cold air intake, stock everything else.

Later at a different dyno with the addition of Mugen 4-1 headers made 120fwkw... Then again, on the 2nd dyno shop with the addition of a Mugen Twinloop catback and de-cat it made 133fwkw.. gains FTW.

EDIT: That compression is shit too.

mate

i dont see what your basing this on

and im sure the proprietor of RE knows more about engine health.

along with the rest of the members on here who are actually writing useful information!

like some of the others have stated, get a full service done first (oils, timing belt, water pump etc) and put on a descent 3" cat back exhaust and high flow cat and pod air filters. these wont be putting too much strain on the engine (or turbos)

also how does ur intake plenum look? alot of paint flaking/missing ? or is it all completely black?

ps. congrats on the purchase, hopefully mine comes soon :|

yeah

that was something i was looking out for

the intake plenum has very minor paint flakes up near the back, as i said very minor tho

and no real indication to show it has been re painted

You don't sound convinced on mods. You obviously want a mild GT-R (which is still excellent!) so leave it at exhaust/intake/ECU and remove the boost restriction is my thought on that.

Otherwise i'd fork out some decent cash (like $1000+) on some heavy servicing because it's an old car. If you want to avoid a rebuild then spend the time/money to freshen up the engine, drivetrain fluids and other worn parts (oil/water pumps and things like brake rotors/lines, suspension, clutch, belts).

I'd spend big there before modding the car, if at all. The car will run better and do it for longer too.

Stronger car = safer mods

Have fun!

Another thing i could suggest is whilst doing the timing belt(and tensioners) is pull the oil pump off and loctite the bolts that hold the two halves together. I would do as you suggest and leave the boost down. When you want to turn it up, get some steel wheel turbos and a remap

    • I use the flattest and most level piece of concrete I have. And then I shim the tyres on the low side of that with sheets of plywood to level the car. The right amount is easily found with a 2m straight edge and a level or digital angle finder. I use both the spirit level and the same digital angle finder I use to measure the camber. Gives a zero check on the angle finder right at the start.
    • Hi guys,  I'm chasing a recommendation for a turbo charger to suit 600whp.  Engine is a RB25 series 2, with rebuilt forged internals with 8.5 comp ratio. Cams are 262/272. I was considering buying a Garrett G30 770 with 0.83 AR, would it be best to get a V band inlet and outlet to suit as I need to buy a 6 boost manifold as well? Thank you.
    • Hey Duncan,  What you did with the boot is mint, I'm going to do the same with my R33.  Do you no longer like the R-Chassis?
    • Just keep in mind (maybe too late now) that before you go crazy, most driveways aren't flat. This _can_ affect your dynamic camber and heights too. It is kinda funny but getting people to really align stuff right can be problematic for people with OCD. Consider a motorsport place if there's any around, and also consider you may have 'dynamically' altered your own camber after a visit to the track, which can happen too.    
    • So I got some fresh Kuhmo 275's on the back to replace the crap that came on this set of wheels and put them on with the front street'ers too. But man I was getting crazy rubbage on the rear passenger side which is odd as the previous crap was 275 also and was on there before I added my extra camber. The semi's are also a *fat* 265 and had no rubbing. I noticed that the camber left and right was pretty different. Very little on the passenger side. My magnetic camber tester on uneven ground showed roughly -1.75 on drivers side and less than -.5 on the passenger side.   It would have been like this on the track day. :( I adjusted the passenger arms to be as close to the drivers as I could get by eye. I then used my new fender roller to make some extra space but holy crap the folds on the guards are made from battleship steel! I couldn't get much rolled at all, they were so strong. My alignment is now off with a 30 degree turn in my steering wheel. I'll find a new alignment joint I think. Not only did the last place think my speed sensor cable zip tied to the camber arm was a brake line, they didn't zip tie them back after they aligned it which was pretty poor. Happy I noticed and did it before the track. Looks like they couldn't match left and right either.   Gave the old girl a bath and I'm always so happy with how she polishes up.
