Tiff's R32 Gtst Conversion To R32 Gts25t

[grim32]

Hey Tiff hows your car coming along? All well i hope.

I had some problems last time on the dyno but all fixed now and goes back on the 27th for another go.

[Squishy]

It's coming along nicely thanks!

Me and Nathan spent the whole day and night working on it... we got heaps done!!

JIC castor bars IN!!

Inner guards GONE!

S13 Steering rack IN!!

RB25 head OFF!!

We just have to sort out some new S13 rack ends (with longer threads to suit the magic washers), drilling and tapping a hole in the block for the turbo oil return line and the cometic head gasket (not quite sure on the thickness yet).

I thought the block would of had all the oil and water fittings already there, mine did, must of been lucky.

Have you decided on the comp ratio yet and what boost do you plan on running

You must be using the R32 RB25?? Mine is a R33 RB25.. and it has no turbo oil return line at all but inside the block you can see the indent where it is supposed to be..

We've decided to use the 2mm head gasket which should bring the comp. down to 8.4:1

[Cubes]

A 2mm headgasket drops the comp by ~1 point over the std 1mm h/g.

So given the R33 Rb25DE is 10:1 (I think or is it slightly higher) that drops the comp to ~9:1.

We are using a 1.8mm now so yep i am told it should be around that now.. still high comp but not too much higher than std rb25det comp..

This week me and Mark spent quite a bit of time degreasing EVERYTHING so it was all ready to go when the block was done.. we ended up deciding to rebuild the bottom end...

Yesterday we bought;

new piston ring set

timing belt

1.8mm thick 4 layer cometic head gasket

race series bearing set

conrod bearing set

RB25 power steering pump (non hicas)

I also sanded back the lower lip from my GTR front bar.. ready for repainting...

Today Cammo tapped and drilled the hole for turbo oil return line!!!

SO MONDAY IS THE DAY FOR ASSEMBLY!!

and yes it will be getting a tune ASAP.. hopefully in time for the Jan Drift Day in a few weeks at QR!!

Today the bottom end rebuild was completed!

Tomorrow the head goes back on!!

I still have to buy a manual spigot bush (from nissan?)

and the non hicas power steering lines should be arriving thurs/fri..

So we should have it all up and running this weekend!!

[gtst25]

Yep VL spigot bushes are the same and about 10 dollars

Cheers

OH NOES!!!

My cometic was about $200

[Cubes]

50,000km's and no issues with my cometic.

THe motor still has the same compression as it did when it was new. So.. Very happy as one would be.

yea but yours is almost N/A Joel

pump some boost into her and see how she holds up!

Its been running 1bar through the mid for some time now with my home bodgy tune. Just boost drops to 11psi odd by 4500rpm.

So 1bar from 2200rpm until 4500rpm.

Goes quite hard in the lower gears. Just 100km/h + it falls over.

Has no issues edging out a mates r32 rb30det gts4 gt35r making 270rwkw (17psi) through second gear on a rolling run, he passes in third once we are up over 120km/h. So the mid range is definitely not n/a like, just the top end. lol
