New install

Post by Metalfab_101 » Wed Apr 14, 2010 3:28 am

While i'm dribbling I might as well mention a new install i'm working on. I have a few standard (Suzuki Sierra) engines at home and after seeing the difference a decent carb makes thought it would be interesting to see how it would respond with a set of extrators and individual throttle bodies. I found some cheap extractors locally and throttle bodies on eBay. I think they are a little big at 40mm (it's a 1300cc engine) :lol: but we'll see how she goes! I think i'll certainly need to run it on alpha-n though!!

often people use quad throttlebodies from the 20v 4age for the g13bb GTI motor, perhaps these would be better sized?

I have a g16b mpfi in my Sierra with extractors, plenty of torque.

Ha! I know you from AZ :lol: i'm "Damo" :D over there. I've got a 16v in my Sierra too, but the ITB's are for a R&D engine.

4a itb's are mega bucks usually, I got set from a CBR1000 including loom, airbox and the standoff injectors and fuel rail for $100 :yeah!:

Hey Damo,

Sounds like a good little project. If the TB's are too big you could always get some off a smaller GXSR 750. Should be a straight swap for the ones you have. Also the lastest MS2extra code has a new ITB mode that blends Alpa n and SD modes. I have nearly finished the itb setup on my toyota v8 but the rest of the hot rod still isn't finished.

Cheers

i used gsxr 600 on the escort. 38 mm id and you can spread them out if you prepared to make a new fuel rail. I found mine on US ebay, landed in oz for about $100 with wiring and tps for about $150. i've read some guys choke back the bigger bike stuff to suite, not sure if they make em or turn down carb chokes to suite. Had this in mind for my itb's considering a std 45mm weber has 36mm chokes, but it want an issue

Got my throttles, they're 42mm, off a CBR1000RR. Maybe a little big for a NA 1600 but we'll see. The injectors are about 320cc/min apparantly, but they they are a 12 hole type that have a GREAT spray pattern so i'm hoping that will make it a little easier to get a decent idle. I'll have some parts for the manifold laser cut next week and I can start piecing it together.

It's probably going to be a little tricky to tune, and from what i've read hybrid alpha-n is going to be the way to go.

Got myself an IAT sensor today, so that's one step closer.

I have also been chatting to the laser cutter about parts a manifold for the ITB conversion. Time to brush up on my CAD!
