Post Turn the SVX int a Skyline GT-R

GT-R has 4-wheel steering. So does the SVX.
GT-R has AWD. So does the SVX.
GT-R has 6-speed BW transmisison. SVX has 4-speed Nissan transmission.
GT-R has distinctive styling. SVX has aerodynamics.

GT-R has 20% more hp than SVX. SVX weighs 4% more than GT-R.

Used GT-R: $40K-70K (in the USA)
Used SVX: $7K - $15K. And the steering wheel is on the correct side of the car.

What can be done to squeeze 50hp out of the EG33 without going turbo? BMW gets 320hp from a 3.2L. 280hp from a 3.3 should not be that hard.

Lets put transmission issues aside for the moment. (Our tranny is common with the Q-45 and 300ZX)

Ditch the stock exhaust system which is impressively queit, but probably quite restrictive. On a low production car like the SVX I think finding cams is out of the question. But we can hand polish the heads/valves and extrude-hone the intake. Headers, and perhaps an aftermarket computer. Total cost under $2000 I think.

How far off am I?

I brainstormed the idea, and the by going to a dual exhaust system with smaller less restrictive mufflers, and headwork and such, the SVX motor could make a bit more than 230 ponies. The big thing then would be a major diet...lose the weight, and it would greatly increase the performance.

CRZ_MSL,

I think you missed a couple of important details in your comparison of the Nissan Skyline GT-R and the Subaru SVX.

1) Skyline - Twin (ceramic) Turbo
SVX - Nope

2) Because of Japanese restrictions/taxes most manufacturers state that their car "only" makes 270-280 bhp when in reality they make much more. Skyline is probably well over 300 bhp.

50 extra horsepower in the Subaru SVX...

Kinetic Concepts Performance Muffler + Intake
10-12% over stock (23-25 bhp) according to KC

Unorthodox Racing Underdrive Pulley
5-12 hp over stock (say 8 hp) according to Unorthodox

Stebro Headers (unknown) but say 15-20 hp

Minimum: 43 hp
Maximum: 57 hp

Now...this all depends on if the products work like they say and my estimate of the headers is accurate.

Bingo...Merry Christmas.

Personally...I want FORCED INDUCTION!!!

I know about the turbos in the Skyline . But for reasons related to the effects of a high fiber, low fat diet I prefer non-turbo cars.

Oh my, am I about to use the replacement for displacement argument? NOT!

I went to the Stebro site, they have an exhaust system but no headers.

You are correct...the Stebro site does not list headers as an available product but RUMOR says one will be available...when, if, how much, etc...I don't think anyone can say.

In the SVX all modifications will both be expensive and hard to find. But I think in the long run...it would be cheaper/quicker to go with forced induction than to modify a n/a engine to the same potential.

I could be...probably am...wrong.
