Criticize My Turbo Build Plan

[Northern]

1 - Late model coolant system conversion - moves the expansion tank to the left side, swaps the inlet/outlet sides of the rad so you can use E36 or Z3M radiators (and as far as I know these are easier to source). Downside is that you need to buy hoses, radiator, expansion tank, water pump (or blockoff the extra port on the early WP), crossover pipe (which is hard to source, and you need to find a way to mount it since the early timing belt cover doesn't have the mounting provisions), and move various electrical for coolant level sensor (and I think fan switch on the rad?) If you can find someone parting out a late car and rip everything off it, that would be the easiest way.

2 - No real opinion here. I had a 4-gauge pod in the center vent, but the Oil pressure and oil temp never worked. I eventually relocated AFR into the instrument cluster where the Check light used to be, and I just use my GFB boost controller as my boost gauge.

3 - I'd send it with the cheap BOV until you have a problem.

4 - No real opinion, in Canada and with AC deleted, I have been fine with a slim SPAL 16" pusher fan (I can't find the model number, I thought it was something like 1.85in thick so I assume the CFM are low) between FMIC and rad and the 88deg Mercedes fan switch.

Cheap BOVs are fine. I've been running ebay piston style BOVs on my E30 and E34 for years and they don't give me trouble. I see no reason to spend hundreds of dollars on a BOV, the consequences of it failing are a boost leak or compressor surge and while you don't want either, you can easily ID the problem and order another. You'd have to go through 3 or more of them to equal the price of turbosmart, tial, etc. Wastegates may be worth spending big money on, but I have a cheap ($100 price range) tial knockoff on my wagon and it works fine too and I'm not worried about it failing to open because I have overboost cut in my tunes. Fans though, always get the biggest fan you can fit and don't buy the cheap ones because they're crap. Buy the fan after you have everything else installed so you can measure up instead of guessing. I use a trick delta pag brushless fan as the pusher on my E34 since I needed something beefy to make up for the condenser -> 3" intercooler -> radiator stack. Expensive but man does it move air. I use an A pillar gauge pod that was sold as for an E30 M3 on my E30, the fit isn't 100% perfect but it works and I much prefer it to losing an AC vent or having to look down under the HVAC panel for my wideband and boost gauge. I put my oil pressure gauge where the OBC used to reside using a little panel I 3d printed.

Injectors - I ran deka 60s for a while and couldn't get the idle smooth. There are off-the-shelf 60lb-ish Bosch EV14s that IMO are better and not much more money.

Do you have a p/n for these by chance?

I think the one I was thinking of was 0280158123 off a 997 Turbo? It has the EV1/JPT connector. Downside is that I think it's shorter, and has a longboi tip - I think you can buy adapter/spacers for the bottom, but I think a lot of people just run them as they are, spacing the rail down or with an injector hat. I think 57lb/hr.

0 280 158 298 is also 57lb/hr but USCAR connector. Medium length/no longboi tip, like the 52lb (0280158117) I am running - I also have injector hats with filters in them to bring them to the same length as an EV1.

I also have 0280158040 bookmarked, which is 980cc/89lb/hr, I think off a Ford Falcon/Barra. EV1 connector, short length, longboi tip.

I think there are a ton of other options, just make sure they're not specifically for CNG or anything else non-gasoline, I know those were popular with the Sloppy Mechanics group for a while, but they start doing weird shit as temp changes. and buy from somewhere reputable for obvious reasons haha
