Would itb's with a plenum around them perform much better than an intake manifold with velocity stacks and just one big throttle body?

The plenum chamber or the throttles? Ideally you would have a selection of ram tubes that you could change on the dyno as i doubt there is any info out there as to what is "the best"
 
Plenum around throttles is easier to get right.

Hey Steve maybe you should build one of these engines instead. Insane!

Thanks Bud, but I cannot return to the turbo after the last few experiences. I think its a mad set up but not for me.
Mine will be the 3.5ish V6 with some tweeks which will be aiming for a 1.05ish time at Wakefield and a solid run in the 300km racing in future years. Quite achievable with the V6 or a 230kw 3SGTE.
When its running you will have to join us for a day of musical chairs.
For now, I have done nothing on the car aside from rebuild the 3SGTE ready for sale. Will provide some info once the build is under way.

The 2GR-FE has been stripped, cleaned, inspected and now ready for the machining.
The plan is for major head work. This will involve port and polish, increasing the exhaust flow, stronger valve springs and camshaft upgrade but the rest will be pretty standard. Head studs will be used with the bottom end staying in a pretty standard set up as its very good in this state.
The intake will be standard aside from a 75mm mechanically operated throttle body. After a few discussions with people who have worked on this engine, this is all that's required for my level of entertainment.
Power output? Hard to say an exact figure but anything from 200-250 rwkw.
I have received the Racepak dash and power module but have not started with the installation. Really need to get this up and running.
Still out on the ECU but at this stage I have enough to keep me busy.
Here is a video clip of the dismantling of the engine:

As I did not have the car ready for the Wakefield 300, I still managed a arrive and drive deal with Tampered Motorsport. They had a Nissan Pulsar Cup car available for the race. My co driver was a young go karting hot shot who had driven the car in the first round of the series a few weeks before the 300. The car was very poorly set up when we arrived but after a few hours work I managed to get the car to a decent set up the night before the race. While it was still in a poor set up (30mm toe out up front/15mm toe in at the rear/camber was steering the car off the track/car was too low with crappy roll centres) we went out in the rain where I qualified mid field.
On the race day, I started the race where I was held up at the start and then had to work to catch up and start having some fun. We were going well until the pit stop when it was discovered I had destroyed tyres! We had to take a tyre change/fuel and driver change. That hurt us a lot then my co driver went out and had a go. Unfortunately we suffered a clutch failure (all the pucks were stripped off) which ended our race.
One thing I can take away from the weekend was breaking the lap record for Pulsar Cup cars at Wakefield Park with a less than perfect set up against many teams who have been racing these cars for years with well developed cars.
 
It would be great to have a team of guys from the forum get together to campaign a car in the W300 2015. Ian and Pete have helped out in 2013 and hope we can do the same in 2015.
 
Here is some footage from my incar camera: I will sort out some better footage in coming weeks of some cleaner driving.

I lost mid-range torque though. You really need to rev the tits off an engine with throttle bodies to get the full benefit. Make sure you change the cams when you do the build.


Not competely true. Ive seen s2000s with ITBs which gain maybe 10hp in the top end but massive gains midrange. Its all about the length tuning (as trav mentioned before). Tune them for top end or you can tune them for mid range, as trav mentioned dynoing with a bunch of lengths to find the length for what you want to tune for is pretty much the key.

I just had a chat with someone who ran a simulation on the recently ported heads. His work is unquestionable at even the highest levels of motorsport.
With 12:1 comp/cam/exhaust/intake combination, the engine will make 475hp at 7400rpm. Impressive to say the least and a great goal to work for. I have requested a simulation on a boosted engine at 4 and 10lb for supercharged options. Not for me, but more on this soon.

Hi guys.........Can anyone give me some insight into "Autostyle" @ Hustville or a competitor that is doing it a little tougher to give a potential customer the courtesy of replying to my emails. I'm looking for someone to help me with exploring the next (probably another stupid) idea I have to getting myself a nice everyday SW20 hard top (cause sure as hell if I havent been able to buy one now - I never will). OK so what I propose is this - import an excellent whole late model HT GT as a "race car" - buy the cheapest piece of complianced crap I can find here - dismantle both - and build what I want here from scratch (like I mean from scratch!). Has anyone thought of this? Am I gonna face more barriers - like will it blow out beyond Lotus Evora costs - if I can even find anyone that will talk to me about it? If I'm sounding like an complete f___n idiot - please dont feel afraid to let me know what I already suspect!

Start a new thread on this forum asking specific questions about what you intend and the people here will help you. You aren't likely to get any responses to the very broad questions you have asked above.

Ahh, apart from starting your own thread as suggested, i think part of buying a car is not just making a few long phone calls and asking a lot of questions - but actually going to view the car you thought of buying. Asking someone to drive on a 180k or so round trip for you to 'inspect the car' is wishful thinking.

I don't understand the point in adding this comment to the thread. Also do not understand what you are looking to do. If you are looking to build a track car, look in the race/rally menu on the forum. There is enough info there to get you started. I know of a great hard top which is stripped down ready for a rebuild

Lol! Oh yeah, have been considering downsizing.
