If the rod is out to far it will not allow fluid in either. 71's usually need it lenghted but with out pulling you MC back off there isn't a way to know. You should be able to do it with out taking the brake lines off again.

If your fuel pump cannot supply enough volume your pressure will drop at higher RPMs. I would T in a cheap ($5) gauge and watch it at WOT.

I have always used black 1200* paint from either Checker( I think it is Duplicolor) or VHT. They make a silver too.

Anyone know if they use the same bellhousing bolt pattern on the engine?

It seems that you don't have your wheels yet if you are deciding between 4 and 5 lug. I would look at your wheel options first. There are more 5 lug options without spending alot and you can run 17x 8(or 9)" fronts, 9" rears without going custom. If it's a street car 12.2 " is plenty.

Exhaust flow spools the turbo. Less timing = less power = less exhaust = slower spool.

Don't think so, helps reduce knock though. jtmny1999... At what rpm are you seeing 12 psi by? 3k?, 4k?

Alot of MKIV guys run twin pumps, run in parallel. Usually Walbros but you could run another Bosch.

Ya, that's the same one I found. Power seemed to drop off quite a bit for something with a 7k redline. I found a VK56 dyno too. http://www.pixagogo.com/Photos/Albums/Photo.aspx?id=S4efVzZhFCIo5cjj-KPBChelKY1uMXgiAk2ZqcxpiIp3AwPt!eFsO5Bw__

Nismo, HKS, Greddy injectors = Nippondenso. I hope they were atleast new.

Does any one have a dyno of a VH45/Q45? I've looked all over an only found 1.

I've been running mine for atleast a year, maybe longer. No problems.

Wow, what injectors are you running? I would think atleast 720's. That's going to be fast.

AZC Z kit fronts are Superlites, the rears are dynalites. You may have been looking at the SX kit.

Go with the stiffest one you can safetly if you plan to run higher boost with 100+ octane. If you run a 8 psi spring, and turn it up with a boost controller it will have a difficult time holding steady boost at higher rpms if you run over 18 psi. I tried it. I ended up running a 1.2 bar spring as I will never run less than 20 psi.

I run 35mm WG's on both my Z's. Turbonetics deltagate on the 71' and Stonemountain(Tial copy) Ebay special on the 73'.

You can alos use a press, that's what we have done on many but most are a mother to get out. Why not just let the CO sleeve set on the original weld bead on the strut tube after the perch is cut off? This is what I did on my cars.

Turbo pistons have P90 stamped on the tops.

Given that you you only want 450, I would assume crank HP and you want to do it on pump gas. A stock block L28 can do that with a full T4 turbo and enough fuel on pump gas. I know I did it. You could even run additonal injectors for fuel to keep it cheap. If you have a turbo L28 already I would run that. The trans is weak, I have broke one(5th gear) but they are only $100 at the local pick and pull. If you go the 7M route you will still need a larger turbo to make good power and a metal head gasket. Clutch and injectors are good for 400 rwhp. The 1JZ's stock turbos might make 450 crank, not sure. The can rev like a mo-fo though due to the short stroke just like the RB26. They also use the R154 trans like the 7M. I like the 2jz but they are double the cost of a 1jz. A vh45 with a lower CR and a T72 at 18 psi would be pure evil. I've seen them for $800-1300 on Ebay.

I went from 8.4:1 down to about 7.5:1 on my 7M. I didn't notice ANY difference in off boost power or lag. If octane wasn't an issue for me I might of run 8.0-8.4:1, but I like to make as much power as I can on pump gas. I can run about 20 psi on 91 octane with out H2O, 24-25 psi with H2O, up from about 14 psi with the 8.4:1. Stock L28T pistons can take 20+ psi all day long as long as you don't detonate, I do it everytime I roadrace with cast pistons, 1/2 hour at a time. Electramotives numbers aren't anything magical. Port a head, more cam duration and rev it to 7500 rpm. Electamotives would be about 470 rwhp. That kind of power could be made with 7.4 if the head flowed and the turbo was up to it, just like theres was. 20 psi from one turbo may only make 300 (stock or upgraded T3) while from another it will make 500 hp. Dapiper on this board made 450rwhp @ 20 psi, don't know his compression though but not far of from E motive made. The size of the turbo has to match the power you want to make. If it does more boost will = more HP. Boost and rpms are the only way to make more power form a given displacement. A T3/4 won't get the job done if power is your goal, it doesn't matter how big that compressor is it's the T3 side that will limit you. It will spool fast at 2500 rpms which seems to be important for most, that is until they realize they only make 250 rwhp at 15 psi, but atleast it spools fast.
