1915 VW versus 2.5 V6 versus WRX motor

Baja Wes · 2002-08-27T07:06:52+00:00

Baja Wes -------------------------------------------------------------------------------- For those that wonder about the differences in power and performance of the three, check this out; http://www.offroadvw.net/bajawes/V6_baja/compare.html --------------------- blue74l -------------------------------------------------------------------------------- I dont understand Wes ???? I know a few 1915's (Greg Ward for one) and man....that puts a shitload more than 100 HP out. I know a few Rex's and NO-ONE runs ULP For MY taste i would have the sound of the Webered 1914 ANY day I would rather rebuild a VW motor over either the clips anyday ok...ok...just not my cup of tea.........maybe we need a "conversion perversion" section Have fun anyway ------------------------ Baja Wes -------------------------------------------------------------------------------- The HP curve for the 1915 was taken from a Hot VW's dyno test on a 1915 with unported Street Eliminator heads, twin 44IDF's and everything else very similar to my car. So the HP curve for the 1915 is about right. I know greg and CT have a lot more HP out of their 1915's, but they have spent a lot more than $2500 on them. The 1915 sounds good for a vw motor, but it has nothing compared to a nice high revving jap V6, or the growl of a wrx. The vw motor is 30's technology, it is now 2002 and it's about time we move forward and embrace todays engine technology I had learnt almost all there is to know about air-cooled engines, and my brain wanted a new challenge. Now I am learning everything about EFI engines and loving it. --------------------------------------- blue74l -------------------------------------------------------------------------------- Yep....cool.... ----------------------------------- Che Castro -------------------------------------------------------------------------------- yeah the type 1 and even type 4 engines are archaic, but i still think it's amazing how much power can be extracted from them ------------- Blown T three message deleted cos he is being very weird and acting in a criminal manner ----------------------------------------------------------------- -------------------------- Baja Wes -------------------------------------------------------------------------------- The VG30 is too big to legally put in a beetle/baja. The 13B has absolutely no torque down low, and would be way worse than the suby motor in the low down torque area. I was originally going to build a supercharged type 4, until I started costing everything and realised how expensive such an impractical engine would be. Even if you do it yourself it would cost silly amounts of money. You would be hard pressed getting the cost of the EFI below $2000. ------------- Blown T three message deleted cos he is being very weird and acting in a criminal manner ----------------------------------------------------------------- ------------------------------------ Baja Wes -------------------------------------------------------------------------------- yes but even if you get it to work you still only get a primitive form of fuel injection, and the computer still won't control the ignition which you need it to do if you want to get the most from EFI. The EFI on the dune-buggy site is pretty rough, I speak (by email) to Todd sometimes. He has alot of knowledge. Do you have a VAF/MAF or are you going to use a MAP? Either of those aren't cheap. You'll have to size and buy correct size injectors, I imagine the commodore ones will be too large. The EFI on a newer car's engine controls more than most people can imagine. If you go supercharged/turbo charged you would want a knock sensor and control in the ECU too. The mazda engine also has, climate control air con, decent heating, variable resonance intake system (gives the broad torque band), knock sensor / control, air temp correction, air pressure correction, 90 amp alternator, direct port injection, and other goodies I can't think of right now. It seems silly to me to try to modernise an ancient vw motor when you get so much more for so much less from a jap motor. But I would love to see your motor when your done. I would love to go for a drive in your car and I'd love to take you for a drive in mine so we can see the real world difference of the two styles of motor. each to their own ------------- Blown T three message deleted cos he is being very weird and acting in a criminal manner ----------------------------------------------------------------- ----------------------------------------- kruizinkombi2 -------------------------------------------------------------------------------- Very good page, Wes. Keep it coming. Its probably not my choice of engine, but your rationale is sound and your research is excellent. Colin Richards kruizinkombi@msn.com ------------------------ Bug racer -------------------------------------------------------------------------------- I would have put a VR6 motor there . Or an Audi motor , just as long as…

Im a little biased, but I would go with a mazda rotary. I got mine for $400 US from a wrecking yard and it puts out about 160hp with a weber 48IDA. It sounds really good and the competition will be blown away as you are blowin past them at 8500rpm! 😎

I had a green 67 full bodied beetle, with 1600 single port for 3 years, then put 1800 type 4 in it, then crashed it and put a 57 baja body on it, with the type 4, then put the 1600 single port back in it (wa hey, 85kmh in a head wind MAXIMUM 🙂 ), then sold it, then I had a 78 kombi with a 4.4L v8 in it, and now I have nearly finished my 73 1303 with 1835 and twin IDF's. I ENJOYED ALL OF THEM !!

My point is - vw motors are cool (anyone here ever driven an oval with 36 of the best hp ?) in all their forms. VW's with conversions are great fun (the kombi really used to turn some heads), an excellent way to get power cheapishly. Each to their own.

hehe personally i dont like the sound of a rotary, but i like the sound of a Subie EJ20... nice. I would really like to be able to have a modern engine that doesn't overheat, drop valves require so much maintainence. its just that i would prefer having an antique flat 4 aircooled engine because i want to be able to say it has a vw engine in the back.

some people dont care whats pushing the car and thats fine for them 🙂

The point i wan't to make is that if you think it is such a bad thing to put a non vw motor in any vw ,then you controdict yourself.My view is this,you cut the shit out of your vw to make it into a baja,you put non vw wheels an tyres on it ,maybe a fancy steering wheel,cd player.
As for end of discusion you would do all of us as well as wes a big favour if you just posted posative things not your biased opinion.
wes ,keep up the good work .
what a boring world it would be with out blokes like wes.

Heated topic ay...
Anyways, i've got a bug with a EA82 in it... it goes well and the turbo sounds like a treat when she flares up - then of course the wastegate kicks in and it sounds even better. The mods for the EA82 are minimal - cut a bit outta the fire wall and your set, it's not much wider that a bug's motor.
In regards to costs etc, an imported EA82 with computer, wires still attached etc will cost a little less than about $1200 which means if your budget was $2500, you could go for a bigger turbo 🙂 Plus the standard VW gearbox - I use an L Bug Box - can hold the EA82 power a lot better i'd say. I get 96kw at the wheels and it's enough to lift the front... do you really need more? 😉
an EJ20T ($1600 approx.) is alot bigger - which means more mods and space needs to be cutted out of the engine bay - my advice, buy the smaller engine - put an intercooler and a bigger turbo and your VW will fly anyways, for half the price and less hassles.

vdub2c, I would love to see some more info and possibly pics of your car. I wouldn't have thought you'd lift the front on street tyres. My baja and my old L bug would spin the wheels and didn't have the traction to lift the front.

PS: fill out your profile when you get a chance.

Hey Wes,
Yeah they didn't for a while, then i put 9 inch rear wheels on the thing (welded two guards together to get one fat one 😉 ) i had ten inches for a while, but they stuck out too far and the RTA had a hissy fit. As long as it's not i the wet it lifts about a foot. only did it twice though, i'm over catious about the gearbox, i don't like dropping the clutch at all... plus when it lifts - i shit myself 😉
As for photos, my camera is rooted at the moment, but as soon as it's up i'll be sure to get photos on the site - I'm selling the bug if you're interested! 😉

Keep Cruzin'
