a.) 1990 R32 GTS - T turbo version RB20 DET Engine
b.) 1991 same specs and a 1992
c.) 1993 R33* GTS 25 T turbo version RB 25DET Engine
d.) 1989 same a B and A
2.What size motors are they? is the RB20 a 2.0 and a RB25 a 2.5?
3.What are the rules to driving on the road in Pennsylvania with a right
side driven car?
4.Where do you guys get your parts from?
5.any 1/4 mile times for these cars stock?
6.If you had to choose one of these cars in order which way would you choose them?

Please help me im getting ready to buying an used one to see if i like it and how much fun i can have. SO price is an option for right now so thats why i cant afford an GTR Thank you in advance for all of your help!

also what happens if you only want to drag this car? and not have it a a daily driveer? i just read the sticky and there was nothing in there. I have 2 other cars that i drive everyday this is just going to be my fun car and take to the track car. 5k miles is pushing it for this car?

1.A) RB20DET = Power: 160kW @ 6400rpm (auto 153kW @ 6400rpm) this is 215bhp @ 6500rpm.
B) should be same as above.
C) RB25DET = Power: 187kW @ 6400rpm, this is 250hp @ 6400rpm
D) If its a R31 running the rb20det it will be a bit less powerful than the R32 versions which run updated versions of the motor.

2. the rb20 is a 2.0 litre and the rb25 is, yes a 2.5 litre.
3. don't know, sorry.
4. don't know, sorry.

5. 1/4 mile for the R32 rb20det's is in the 15's and 1/4 mile for the RB25DET's is around 14.4 seconds, not bad at all.

6. Well, the r33 is bigger and heavier than the r32, but only by a bit. Its got newer technology and bigger engine capacity to begin with so an RB25DET would be my choice. But, I've seen sooooooo many r32 running in the 10's and 12's so I know they're not to be underestimated.

as for making it a drag car, well it depends what times you're aiming for and with which engine. tell us what time you're aiming for and I should be able to give you a rough estimate of how much modification you need.
There are tons and tons of RB20det's and rb25dets running in 12's and lower, just search for it and you'll find all you need to know.

D) is still an R32 and same as the other R32's.

3. Read the struck threads on legalization for road use.
4. All parts pretty much come from Japan with the exceptions of custom ones. Some pistons and conrods from the States.

1/4 times from what I've seen are pretty simular with the R33 being about .4 of a second quicker standard. Basiclly nothing in it.
