R33GTS to R33GTS-T

[Kor'axis]

IF i got a stock turbo off a r33GTS-T would it be possible to mount it onto my r33GTS? I've read some threads on this sort of topic but nothing really like this... so if anyone can point me in the right direction (or give answer) it'd be much appreciated

Dont do it, there are quite a few things that are different in the engine to cope with forced induction on the det engine.

compression my friend.... its the compression that will kill ya.

If you want a turbo car buy that model, rather than trying to turbo the NA version.... it will cost you a heap more to turbo the NA version as there are so many differences in the engine (and brakes).

[doxximus]

either do a full engine, rear end, everything swap like i did (if you really love your car) or just sell and buy a turbo model

pm me if you want a list of parts and aproximate prices of what i payed about 3 years ago

[letemlaf]

i know a guy who changed a mk4 5 sp NA to a 6 sp twin turbo.

i dont know much about how he done it but it is very unstable.

besides for the price and reliability your better off just selling yours and buying a turbo from factory model.

[Kor'axis]

Well, i bought the car for a very low price so even if it costs me $3000 to get the turbo in i still get a turbo r33 for less than the average selling price...

turbo engines have oil squiters in them, NA doesnt.

so if you really wanna convert then its better to just swap engines,

coz you'd need to change to thicker metal head gasket, etc to turbo it safely.

Have you read what most of the people have been saying here? The rb25de engine runs much higher compression than the rb25det, this means if you bolt a turbo onto it it will more than likely ping due to the boost and high compression. It will cost more like $5k (to buy a rb25det and then install it) to do the conversion, plus you still need to change the brakes (well you dont have to but I would as the gts25-t came with better brakes than the gts25). Next you'll be asking about doing an auto to manual conversion... *laugh*

If you're willing to accept any possible misadventure go for it...I've been more than happy with my bolt-on....high-compression can be your friend if tuned right.

It's also true..the R33 N/A brakes are very ordinary 4-stud items...the R34 N/A are 5 stud with twin piston fronts instead of single, you also have vastly different cams to the turbo model.

Check out the N/A section..it's been covered a fair bit

[Kor'axis]

thanks guys i think i'm convinced that getting me a gts-t might be the thing i'm after!

haha i knew it davor!

just stick with what you have got mate, its still a bloody good car. and you just bought it like 1 month ago! and you are on your P's and its illegal to drive an R33GTS-T (if you do and crash it you may not be covered by insurance...)

just learn how to drive in this car properly and later on go and get more power...

There is plenty of information that can be found via a search on here.

But basically not worth doing. Cheaper, and more effective to sell off your old N/a (maybe get $1500 for it), and get an RB25DET (maybe $2500 for one).. and swap the whole engine over.

If you did turbo it, due to different compression, etc you would only be able to run fairly low boost levels (7psi or so). It would work, but if you got that far, you'd probably want to modify it, and then you may as well have got the RB25DET put in instead.

Are you sure about that? I thought you could self-engineer an engine swap if it was an engine present in the model range.

Edit: Here we go... from http://www.rta.nsw.gov.au/heavyvehicles/do...s/vsi/vsi06.pdf, hence NSW only:

Examples of minor (owner certified) modifications are:

• engine changes where the capacity increase is less than 15% above the maximum size engine available for the vehicle (providing no major structural modifications are necessary and where noise and/or exhaust emission ADRs apply, all standard equipment such as carburettors, exhaust systems, exhaust gas recirculating valves, oxygen sensors and catalytic convertors relating to noise and emission control are retained and operate correctly);

• the fitting of a proprietary sunroof (if the modifications are of a minor nature only);

• fitting a “package” available as optional equipment for the vehicle (eg front disc brakes, power steering, alternative transmission and bucket or bench seats);

• additional lighting eg: fog & driving lights;

• alternative wheels and tyres within the owner certified limits set by the Authority (see Vehicle Standards Information Sheet No. 9 Guidelines for Alternative Wheels & Tyres);

• fitting of handling enhancing suspension components such as roll stabiliser bars and up-rated shock absorbers.

Iwells your right, if the engine was offered by the manufactor in that model of car, eg skyline then you dont need an engineers, however you do need to upgrade the brakes to suite the engine specs from manufactor. Thats what i did on my 32.

It waz for future reference... to see if it would be better to buy a turbo or to get a conversion!

oh well... i'll have to wait a few more years...
