1st steps in Project R32

[Guest]

Okay, so I've got the coin to get myself an R32. I saw a couple in the paper and online for sale. Here's my dilema, and primarily why I came to you guys for help...

I dont need to drive the car daily, it's a project car.

I saw a couple for cheap, but had the RB20DET in them. And one had the badboy RB26DETT. And none with the RB25DET.

I personally do not like twin turbos. You get more boost, the way the RB26 runs is clearly nice and ballanced, but I just dont like the huge lag.

Would there be any loss of benefits if I bought one with a RB20 or SR20 in it, and swapped the motor for the RB25DET? Just about everyone on the net is running R32 with a RB26DETT, and I wonder why.

Anyways, can you please help me decide what to do? It's either buy the basic R32 and buy a JDM RB25DET RWD or go for the R32 GTR, which already is equipped with the RB26DETT.

Pros and cons, please =)

there is nothing wrong with the rb25 at all.
the reason eveyone likes rb26's is because they are a huge step up from an rb20.
with rb20's limited to what you can do with them and you reach the ceiling of potential alot faster unless you do some serious mods.

For an rb26, there is no reason why you couldnt ditch the twins and go for a single. it's all personal preference. although, i didnt know rb26dett's were all that laggy.
Have you driven one? if not i would do that first.

stock GTR laggy???? it has pos ceramics wheels for a reason

Before you decide which one you want you should probably do some extensive reading about the common problems associated with each on this site. Much of the information you should have before buying one will be in the stickys. Also make sure your have the money for the purchase price and then some. When these break repairs are extremely costly, look at the project build threads for info on the costs associated with parts/rebuilds.

Also there are plenty of Skylines for sale on this site which you should consider, often you can find plenty of info on the vehicle through build threads and searching.

Good luck finding your Skyline.

Thanks a lot for the info. I will definately do some reading here, seems like a great resource.

I didnt think the RB26 could be single turbo'd, because of the way it's setup. Each turbo powers 3 cylinders.

And I've driven a few twin turbo'd cars (93 RX7 Mugen edition, and 300Z 3.0L TwinTurbo) and both had some amazing lag on stock turbos.

Compared to a few single turbo civics I've driven, the lag was much longer. Apparently there's worse lol

I'll definately do some reading, thanks again.

Welcome to GTRC, and you need to do a lot more research.

Apples to oranges, please do not compare a single turbo civic to a TT like RB26DETT. WTF is a mugen editin RX-7? I think Mugen might take issue with their name being associated with a rotary engine (pssst! Mugen is a Honda brand).

Stock, the RB26's twin ceramic turbos show little to no appreciative lag. The problem with them is when you go to bigger hp applications the ceramic breaks.

I've driven a single turbo RB26 and it's fine, the size of the turbo makes a huge difference in how power comes on.

Always remember that just because you can afford to buy the car doesn't mean you can afford owning the car. Do your due diligence and read A LOT before jumping into a potential nightmare.

You'll do well here, lots of info on GTRC...search, read, digest, search again

it depends on 2 things really.

#1 your goal...

- if your goal is to get something that can do really big power, like more than 500 WHP, and you want to rebuild the engine, and change turbos to a big single... then it sounds like the RB26 is your engine.

- but if you want a car thats less expensive, but has less potential they top out around 400 whp on some of the best built RB20's....


#2 your budget...

- take it from me, its VERY easy spend upwards of $40,000.00 on a GTR... and it doesnt even get you to the top!

-------------
heres a perfect example of a single turbo conversion GTR: http://forums.gtrcanada.com/skylines...500-51104.html

you've got it backwards brother... the single turbo RB26's are the ones with lag... people who run twin Garrett GT2860R-5's or -7's will see full boost as early as 3,500 rpm! twins have very little lag.... big singles have lag, but when they kick in.. omg do they ever punch

that being said though, the engines are not the only differences... you need to do more research into what you want to use the car for first: theres 3 main cars, each good at different things:

a) Skyline GTS, GTS-T, - these have the RB20 and RB25 variants.. rear wheel drive only, and HICAS. theres also the GTS-4 which has AWD + RB20/25 these use hydraulic lifters in the head... really suited for drifting

b) skyline GTR - this has the 4 wheel drive, HICAS, twin turbo RB26 motor. these use solid lifters in the head. really suited for time attack, or lapping cause of the AWD.


all of them are inline 6 motors.

hope this helps u clear the air a little.

Did I really type Mugen... Doh I feel like an idiot, and more of one now that I cant remember the Mazada term lmfao.

1993 RX-7, 1.3L rotary with twin turbos and an awesome body kit. All stock from the factory, only available in Japan.

I am not looking to make rediculus horsepower. I am looking for a car that can be versitile, for short technical tracks like Shannonville. And something that I can open up at a large track.

1/4 mile is fun, but not my scene.

And drifting is fun as well, but I'm not interested in blowing wheel bearings, brakes, differentials and tires like they're free.

If I was cheap, and a bandwagoneer, I'd buy a Honda with a GSR and turbo it =)

single a RB26 and youll be laughing...T04 or T51 (thats what my goal is), youll have your lag but will build HUGE power higher in revs

+1 sounds to me also that you would best enjoy buying yourself a skyline GTR... possibly find one with a blown engine, or with an already built engine.... then put a single turbo on there like a HKS t51Kai or T04z etc.... all good stuff....

that setup will be perfect for the tracks you mentioned... a big single is a lot of fun on the straight aways, and make sure you get some well suited cams to help comepnsate for the bigger turbo lag.

most GTR's can be had these days around $16 k with a built motor.

RB20 is the most reliable and best for a DD IMO.
The rb25 is pretty reliable as far as I know, should be good for a DD with some maintenance.
RB26 is a beast, has the most potential to be modded. Can be reliable for a DD but requires more up keep.
Go for the 26 for a project car for sure.

I really don't mean to sound like an ass but you SERIOUSLY need to read up more on stuf about Skylines. Twin turbo is the least laggiest and produced less boost than a big ol single but less power. Single=Big power, Big Lag, Twin=Small-Medium Lag, Moderate power

[dscarps]

Yeah, you're right. I am a bit misinformed, and a noob to skyline building. Please dont shoot me for it =) I have a lot of homework to do, and have received a lot of great direction from this group.

In many other vehicles, it's not the case. I am now assuming the twin turbos on a skyline are run in tandem. If you run them individually (like on other vehicles in my limited specrum of understanding), they have a longer lag than one small turbo.

Are there stock colours on R32 skylines to be aware of? Maybe a particular bad year? Like Volkswagons from the early 90s, there were a few colours that predicted a troublesome future for the vehicle's body.

[flipridah17]

I think the earlier gtr's had oil pan issues but nothing too major.

Honestly man, you will be very happy with RB26DETT. I owned both RB20 and RB25 but nothing compares to RB26DETT.

Just my two cents. Good luck to you.

RB20 > ALL

Unless you have 20k to dump into a 26.
