R32 GTR Rebuild

[fsmout]

Hi everyone,

What are peoples thoughts on using shot peened standard rods or forged rods with forgged pistons if i want to run 1.5bar reliably?? I don’t really have the cash to go for the fogged rods, but I can afford to get my rods shot peened.

I will be getting the crank machined, engine blueprinted and and rebuilt with 87mm Arias Fogged pistons, shot peened rods, ARP rod bolts and new bearings along with sum baffles and new gaskets etc. I have Group A turbos, intercooler and bigger injectors. Apparently before i got the car it had dynoed over 300kw at the wheels, so i would like to achieve this aith the new setup.

History:

I just bought a R32 GTR 2 weeks ago and on my first night out piston 4 had a piece of metal come from somewhere (ring/detonation???) and F$#^*$ked my head!! So i have owned it for 2 weeks and the car has been in the garage for most of the time. :_(

It had been rebuilt 13,000kms ago by Unique MS in Sydney and i was aware that there had been some damage to the cylinder that failed cylinder as the compression was down to 90psi.

Cheers,

Im running basically the same setup. Upgraded bearings, standard rods shot peened with ARP rod bolts, Arias forged pistons, metal head gasket, o-ringed, balanced and blue printed. Used to run 1.5 bar on HKS GT2530's with standard camshafts, and now 1.25bar with Tomei poncams. Has been running for 15,000kms with no hiccups whats so ever (well at least in relation to the engine build).

I was told with the standard rods, keep to the factory rev limit and you wont have a problem 350awkw and under. We had part of my engine apart a few weeks ago and everything still looks as new.

EDIT: I as wactually told more than 350kw for the shot peened rods at factory rev limit, but 350kw is ample for what I want from the car.

As Amaru said,

Keep same revlimiter and they will be fine

They should have no problems running at 1.5bar. But if you go the aftermarket cams you can run lower boost at the same power level.

Having see what happens to shot peened rods after 450hp i would spend the extra dollars.It's much cheaper to do the job once v's doing a whole rebuild again because rods bent.

sounds like you bought doge GTR,do you mind i ask you how much you pay for the car?couse i just want to know,if you pay right price for GTR,you should get very good example GTR,they are very strong engine,

i think you should bring the car back to the guy who sold the car to you,

good luck mate,

yeah i did get ripped a little, but apart from the engine the car is super clean and has nice mags & good suspension. I thought i was getting a good deal for a R32 93 Vspec with the Brembo's etc but with the rebuild it will work out to be a little over market value. Thats the risk you take i guess.

Thanks for the comments above - i really want h beams but i cant afford them with the whole build, so i think i will have to settle for shot peened.

I will be getting a light port & polish, but once again i can afford to get cams at the moment.

[fsmout]

it was $27,000 with 98,000kms

would'nt you be better off putting the h beams in now, it's easier to put the cams in later than it is to pull it apart to put h beams in.

I agree. The $1600 extra you will spend now on rods will far outweigh the cost of a rebuild later on. Beg, borrow, steal (j/k) if you have to, but do the rods now.

[PurpleR32]

I also agree. Do it once, do it right. Just cut back on other expenses, girlfriend/wife, rent, food, water/electricity

or just wait and save

Trust the above few posts - once you've got the power bug, it bites hard. Especially so in an R as it get the power to the ground so well.

A year or so down the track when you're strapping on those high mount(s) you'll always have the thoughts of those std rods in the back of your mind. While your at it, check to make sure that the crankshaft/oil pump setup is of the later type.

hey mate,sounds very cheap for 93GTR V-spec,General V-spec GTR32 sell over 40k,you pay 27k+10 rebuilt,still cheap,make sure its General V-spec.

also do the rods once,extra money spend,but much stronger

[oh to dream]

do the rods and dont be p!ssed off about the buy, after the rebuild the engine will be bullet proof and the car will be proper market value for a 93 V SPEC!!! atleast this way you will know the capabilities of the engine, so consider the rods and the rebuild as cheap insurance for the engine/car and peace of mind.
