Turbo? NOS? Engine Swap? High CR NA build? How would you modify your engine?

mclaren1885 · 22nd August 2007, 19:27

As the thread title mentions there are many ways of getting additional power. But what would you choose?

Turbo: One of the most exciting and complicated ways to get additional power. The turbo whine and the BOV whistle is to die for. The push you get away from the steering when the turbo kicks in is something I wanted all my life. Based on the boost, power increase may vary from 30bhp (8psi) to twice the stock power (@ 1 bar). Costs generally lie between 1.5L to 5L depending on requirement and engine specification.

NOS: One of the easier ways to achieve larger gains in BHP. Can be put to almost any car. Easy to install, provided you know the jet sizes and the maximum allowable shot on your engine. Its easy to overcook it and blow your engine otherwise. Engine internals will take a beating. Also, best bang for the buck going by the cost per bhp to rupee ratio. Though care has to be taken that the bottle temperatures are maintained.

Engine Swaps: A trend that goes back a number of years. Started off popularly with the swapping of esteem engines into zens. Now you can have e-zens, b-zens, zondas, OHC with B16s, Lancers with Mivec et all. But what about other cars which do not have an option for further engine upgrade? If you get a good engine, get it installed from a reputed tuner who knows how to fabricate custom mounts and to troubleshoot any kind of problems that may occur. The tremendous PTWR works wonders in such builds.

High Compression NA build: Involves bumping up of compression to get the additional power. Basically all the mods that can pull out every ounce of juice from your engine without going Forced Induction. Includes shaving of head, use of high compression pistons, cams and lots more. This will require the engine to run on a higher octane fuel.

All of the above mentioned will give you significant margins of BHP gains. They all are a stage above the regular intake/exhaust, port & polish mods. So given the chance what would you do to your engine?

Engine swap to 4G63 Turbo for me

.

n_aditya · 22nd August 2007, 20:04

Turbo was my most preferred option. But i voted for an engine swap. Why? so i can get the best of both worlds. First the engine swap and then a turbo on it. (considering i'll still have the esteem and will swap the engine for a suzuki GTi engine). Otherwise an engine swap which already has a turbo setup is my option.

Couldnt agree more.

NA built engine - Turbo/NOS are really not the way to go for small tight tracks such as *ahem* might be found in SCCA Solo competition.

My idea of a nice street/track NA engine build is:

cams with "serious street" type grind (typically below 280 degree duration)
highest compression afforded by 93 octane pump gas for this cam
4-2-1 header with freeflow muffler
IRTB's with a standalone ECU.

This should give enough competition to the turbo engines on the said tight tracks.

Buy an lp640

engine swap + big turbo ... I dont mind the turbo lag...
just love the sound of BOV going off..
..hopefully will catch up with the NA cars when my turbo kicks in

maybe use an ALS ..but then I get my turbo and exhaust screwed up..

vabs78 · 22nd August 2007, 23:01

I love the concept of turbo and how it uses wasted energy to increase power. With the advent of VGT, hopefully in future we won't have to worry about turbo lag.

No wonder you voted for i wont touch my engine, thank you.

I voted for Turbo, obvoius reasons, nothing can make you feel so good like a Turbo does, heck if your car is slower then a NA, the turbo just is so much fun.

dinar · 23rd August 2007, 12:10

engine swap first and than a turbo with boost control [over boost, read NOS].....he he he

mclaren1885 · 23rd August 2007, 12:45

All those of you voting for engine swap and turbo/nos kindly mention which car, what engine too please. It will only give us an indication of the popular choices.

B16 on an OHC (walking the beaten path, till I'm more familiar with the turf

)

I love turbos. But since I already have that, how about a remap?
