R32.. Just Plain Slow.. Too Slow I'm Assuming

Hey, im trying to figure out what (if anything) is wrong with my old r32

Compared to the corolla i'm driving at the moment it's quick, but compared to almost everything else it's slow.

It's a R32 GTS-T with a hi flow cat, 3" exhaust with split dump, walbro fuel pump, R34 turbo, the ecu has been remapped, and it's running 14 psi. it got 163rwkw on a cold night (before split dump and cat) (133rwkw before 34 turbo and remap)

As an example, an s13 with a totally stock rb20, the only mod being a cat back, absolutely slaughters the r32 (i know it's about 100 kilo's lighter)

Anything with the letters SS (anything at all, including VN SS's) leaves it for dead, vl turboes laugh at it and swifts, gti's protons and tx3's give it a good run for it's money (which is about 5k more than most of the afore mentioned), all on the drag strip of course.

What i'm trying to figure out is whether this is because of A) a bad tune, B) a dead engine C) a dead clutch

I have had someone say before that the tune was a bit weird, so it is possibly this.. The tune was done before a split dump and a hi flow cat was put on, does anyone think the tune could be slowing it down this much?

Dead engine i'm too scared to check as it's not my car anymore and if it's down on compression i will feel guilty and probably buy him a new one.

The clutch is going i know for a fact, and it IS the standard one. Slam shifts can result in free revving (as in 7k rpm in 3rd while only going about 70kph) but will this seriously hamper performance in gear? For example if 2nd gear is slowly selected then the boot is put on, the clutch will be properly engaged correct?, or is there a chance that it could still be slipping and that be where im losing power?

I've actually posted this before ages ago when i was the owner, ended up deciding it was just the car, but now i am interested too hear any suggestions (after getting in that little s13 and feeling how much faster it is).

thx

clutch is slipping badly.. have it replaced..

the power figures tell u that it is making power and the engine is not dead (unless sumthin has happened recently)

so it has to be driveline related, gearbox, diff, etc. I am guessing its the clutch by reading ur post

Ah, ok i just wasn't sure if it could still be slipping while in gear (i.e. whilst in second gear, cruising). It fries the tyres coming onto boost in 1st too so i wasn't sure whether the clutch would/could be a problem in 1st. Guess it's time to look for a groupbuy on an exidy single plate or something..

MODS:

Can this get moved to the clutch/drivetrain/gearbox area, as i have a clutch related question and it will save me having to write up a new topic

yeah mate get your clutch changed. its definitely slipping. as for frying the tyres on boost in 1st, all that means is that the clutch is still good for 1st gear and as yet to slip in first. but by the sounds of it...it wont be too long now before you will start to experience slipping in first.

my clutch was slipping badly. firstly it would slip in 5th, 4th, 3rd then finally it started to slip in first, in which case i was pretty much crawling along. mine slipped even in when the car was in gear. changed the clutch to see it was worn down to the rivets. NOT good!

hope that helps!

goodluck mate,

:P

      That R31 was so cool. Only did Orange Park once. Scared the hell out of me.

      The alloy coolant reservoir has a sight glass, so as long as I can see coolant in the sight glass it's GTG, as for PS, it isn't anything catastrophic if it gets low, and as it hasn't lost a drop since I have owned the car I cannot see it being an issue, even after putting the "big block" 2.5 in....LOL The only time it gets slightly messy is at oil changes, as the oil filter sits above the frame, and I need to use a plastic bottle with its bottom cut off to catch the flow when loosening the filter

      Good on you for taking on the job, but it is a big one. Even if you have bolt on manifold and turbo, you will need: Post throttle pressure source to boost controller to wastegate (and FPR, and ECU/MAP sensor) Pre throttle pressure source to top of BOV(s) Oil feed - you can take that from the standard port in the middle of the block Oil return to block under the turbo - this is much trickier than it seems to route a decent/wide pipe past the manifold. You really can't use rubber hose because it is way too hot there, and also the oil out of the turbo core is a bit frothy so it needs to have a decent diameter Water feed - you can take that from the standard port in the rear of the block. Water return - mine runs to a T into the heater box return, just make sure you don't create a high point making bleeding hard. All of those lines should use 200 series style teflon braided hose with heat shielding because everything needs to be routed past the manifold. Also a turbo beanie is a really good idea to minimise the chance of the car catching fire (under bonnet lining in particular) You also need to decide a cam cover breathing solution as well, will you vent externally via a catch can (probably illegal) or return to the intake (plumbing required and can oil up everything over time) Keep in mind the intake and exhaust piping in the engine bay will be custom so you either need to be able to fab ally and steel or have someone you can get a car that isn't running to. Get the wideband fitting welded into the dump pipe at the same time. Also, just my opinion, a screamer pipe attracts attention and doesn't add power, I'd plumb it back if you want to be allowed to keep the car on the road. BTW do you know anything about how healthy the motor is, and what power you are targeting? Doubling or tripling the factory power on an unknown motor is a little risky. Also fuel system will need some attention (pumps, high current hanger, direct power and earth feed, injectors etc)
